Recently, I have been using the cloud mirror of "driving to ask", and I feel a lot, so I will talk about the equipment related to driving safety. In other words, no matter old or new drivers, there are three treasures in driving: tachograph, navigation (with reversing image) and electronic dog, which occupy the top of the windshield and the middle upper part of the center console. After we buy a new car, we will basically upgrade and refit around Sanbao, which is of great importance in driving safety.

In the current car modification market, a product called "Cloud Mirror" is selling well. In short, cloud mirror is a large collection of functions of the three driving treasures. It adopts the appearance of the rear-view mirror, replaces the original rear-view mirror, and operates independently from the mobile phone APP. This solves the problems such as messy and complicated routing, easy to block or offset the driving line of sight. At the very least, the power supply of the cloud mirror is directly concealed from the safety in the car, and the cigarette lighter is finally not occupied by the tachograph and electronic dog as before. The figure below shows that both the DASH CAM and the electronic dog need to take power from the cigarette lighter, which is too heavy.

However, many cloud mirrors still have drawbacks on the operational level. Although the concept of "one button" is mostly promoted, it is actually listed based on the functions on the screen. In practice, complex operations can only open the page with one button, and a series of "pointers" are needed later. The difference is that the solution of the intelligent voice rear-view mirror for driving under Wister is very clear. It depends on voice. This scheme is not new. Many cloud mirrors on the market also use voice function, but there are few scenes, slow response and other problems, which are just like chicken ribs. However, it was found in the use of "driving to ask" that the whole operation can be realized by voice, and the interaction logic is clear and direct, the voice command response speed is fast, the recognition accuracy is very high, and the degree of intelligence is also good, which ensures that the interaction is more practical, convenient, and safe. Next, I will talk about why I feel good about several experience points. I will display the indicators first, so that I don't have to mention them all the time.

"Experience of appearance and installation details"

The advantage of cloud mirror is that the original position of rear view mirror will not occupy too much sight space. Therefore, the volume of the cloud mirror must not be ignored. It is not the bigger the better. If the volume is too large, it will inevitably block the front line of vision, especially when turning right, the impact will be more obvious. Search Baidu for "Inside Rearview Mirror Blocking Sight", and there will be 800000 search results. The first is that the owner's sight is blocked after refitting the interior rear-view mirror.

Back to "Drive to ask", its volume is relatively moderate in the cloud mirror. The following figure is a comparison between "Drive to ask" and the original rear-view mirror of my colleague Ford Forrest, which is slightly larger. On my old Hyundai Sonata, the volume is basically the same, and the vision of the original rear-view mirror is almost the same.

The following figure is a comparison between the self installation and other brands. It can be seen that the number of friends is too large. Maybe what they focus on is the mentality of "buying big with the same money and making a profit". It is conceivable that the situation of blocking the vision is just a blink of an eye. In addition, although cloud mirrors of other brands are large in size, some display screens only have a small area. In contrast, the 6.86 inch display area of "driving to ask" is luxury. In addition, the 2.5D glass and all metal frame you asked about are really tall.

Cloud mirror products involve power supply, reversing image, GPS and other circuit and wiring problems, which need to be installed in professional stores. The installation service of "driving to ask" was undertaken by Mr. Quick Repair. He received the message of installation service information when he received the machine. At the same time, other local installation stores can also be found through the network, which can be re selected and determined according to the location, store level and other requirements, which is more humanistic and intelligent.

In the installation store, the installation master works quickly, and the installation and commissioning are completed in about 40 minutes. During the chat, the teacher said that "driving to ask" is the fastest voice response in the market cloud mirror. They are cooperative installation stores, and there are many agent brands, which is still credible. Here is a suggestion, which can be added to the after-sales scoring system, so that users can comprehensively evaluate whether the store installation is professional, whether the process is reasonable, and whether the service is good, as a basis for the rating of cooperative stores.

During the installation, I paid attention to the details of the bracket of "driving to ask". After all, I experienced the shocking moment when the DASH CAM fell down during driving. According to the different models, the "driving inquiry" is equipped with different brackets, which are made of metal and adopt the gland type rotating fulcrum processing method. The rear-view mirror adjustment is relatively stable. In addition, the connection between the fuselage and the bracket is made of integrated steel plate, which is firm after being fastened with four screws. It seems that the quality of the connection between the two does not need to be worried.

On the power line of "Drive to ask", we saw an unusual fuse, which can effectively protect the machine and on-board equipment. In addition, the battery is powered from the fuse box, and there is also a low-voltage protection device, which can effectively prevent the overload of the battery. Safety considerations are in place.

"Experience of UI, reaction speed and voice interaction"

"Ask by car" benefits from the flat "full window", with clear UI layout and obvious partitions. Common function and status labels are placed on the first screen. Sliding down is the application list, sliding up is the shortcut menu, and sliding left is the second screen and the third screen of the home page, which are convenient for some users who like to touch.

From the setting page, we can see that the UI of "driving to ask" is deeply customized and developed based on Android. From the perspective of touch alone, due to the power of the hardware, the UI responds quickly, and there will be no problems of touch insensitivity and slow response after a long time of use.

"Drive to ask" is not completely closed after the car is turned off, but is in a sleep mode with extremely low power consumption to deal with vehicle vibration monitoring and other situations. In this way, every time you start your car, you can immediately light up the screen and enter the home page by asking. The online functions are activated in an orderly manner, and there is basically no need to wait to use them. In the specific test, five or six seconds after the car starts, the Bluetooth connection, GPS positioning and online data update can be basically completed. I feel that the positioning speed is fast. On the one hand, it is directly activated from the sleep state. On the other hand, it is also the quality of the external pull GPS antenna, and it can be assisted by the Unicom card, so the positioning speed is ideal.

"Ask when you drive" has no built-in battery. It is safer for vehicles to get electricity. After all, no matter how good the built-in battery is, it may have safety problems when exposed to high temperature in summer. Therefore, when purchasing vehicle mounted equipment, try not to choose one with battery.

The whole process voice intelligent control is the most important thing that attracts me to "ask when driving". In particular, the common functions can avoid wake-up, directly say voice commands to ask and then execute, as well as interruptible human-computer interaction, which greatly reduces the cost of voice use. For example, the closing and opening of the screen, the entry and return of the homepage navigation music and other function pages, the volume adjustment and mute, the use of photography, WeChat and other functions, these global wake-up free instructions cover daily operations. For another example, voice commands can also be used to search and operate the navigation, and direct voice operations can also be used to play, pause and cut music without wake-up. For the operation on function settings, you need to wake up with "Hello", and then you can switch WiFi, Bluetooth, electronic dog, driving record, brightness, etc. The following video shows the process of interaction with "driving to ask" by voice. It can be seen that voice recognition and response speed are really good.

Ask that there are only two physical keys on the body, namely, the power key and the photo key. They are more used as spare tires, which are rarely used in practice. Between the two buttons are TF card and SIM card slots.

"About functional experience of DASH CAM"

The camera of the DASH CAM for "driving and asking" is located at the back of the car body, almost in the middle of the car body, and can take care of the blind area of the left and right visual angles as much as possible. The camera can be adjusted 360 degrees, and the damping is large, so that whether it is an SUV or a car, it can find the best stable angle.

The quality of driving video recording is fundamental. The front camera pixels asked are 15 million and 170 degrees wide. On the function page, you can switch between 1080P and 720P, control the length of each video segment, and preview the front and rear cameras.

The measured video recording quality is fairly good under different light conditions. The following picture shows the screenshots and videos in the morning. The color restoration is relatively accurate. The distortion of the wide-angle close shot is well controlled, and the distant view is no problem. The license plates dozens of meters away can also be identified. After uploading the video to a third-party platform, the image quality is damaged, and the actual performance is better.

The following figure shows the screenshots and videos of driving at night. Street lights and opposite lights have more interference, and the distance of license plate recognition has been shortened. It is still possible to see objects and people clearly. The wide angle is enough to maximize the shooting of objects and people on both sides of the vehicle.

Each video and image can be directly viewed on the query, and the videos of dangerous actions such as sudden braking can also be seen clearly. The query will be automatically locked and will not be overwritten in the cycle recording. In case of an accident, it is very convenient to obtain evidence afterwards.

"Experience of reversing image"

I call myself an old driver and prefer to use the reversing image more for the convenience of observing the blind spot in the rear-view mirror - the lower part of the boot. There have been many reports of accidents in this blind spot.

In this part of the experience, I first pay attention to the starting speed of the reversing image of "driving to ask". Thanks to the parking standby mode, the screen can be switched from the home page to the reversing image when you get on the car and start up, then shift to reverse gear. In addition, when reversing is required during driving, if the screen is off, reversing will automatically activate the screen, which is qualified.

The following figure shows the quality of reversing image in daytime. Everything is clear, and the picture has its own distance prompt line, which is a reference.

The following figure shows the reversing image quality at night. It was slightly dark at that time, and there were no lights in the parking lot. With the reversing lights and LED bulbs of the rear camera, it was no problem to see the ground clearly.

"About the professional experience of rear-view mirror"

Although "driving to ask" is an intelligent rear-view mirror, you can't ignore your job, that is, does the screen affect your rear-view? The logic of the question is that when you do not send any command within a few minutes, the screen will automatically turn off and only show a few key touch buttons and time. The background navigation, music and other functions are still operating normally.

In the daytime, when the screen lights up, it is no problem to see clearly the screen and the situation behind the car. Because people's eyes will focus according to the point of interest. The focus is in the rear. In the eyes, the screen is the blurred foreground. On the contrary, the focus is in the screen. In the eyes, the rear is the blurred background. If you use voice to "turn off the screen", ask to turn off the screen completely. This is no different from the original rearview mirror.

In the evening, it is recommended to turn off the screen to make it safer. Ask your own electronic anti dazzle device. Don't worry about turning off the lights when you drive far behind.

"Experience of electronic dog, navigation, lane departure, distance warning and other safety functions"

The electronic dog of "driving to ask" is a combination of hardware and software. It has imported ANW radar and real-time data update. The fixed probe and interval speed measurement in its own city have no secret. Although no mobile speed measurement has been encountered, some radio road detection probes with the same principle can receive radar waves and voice prompts such as K band, Ka band, X band, etc.

There are many options for setting the electronic dog, which can set the electronic eye early warning, real-time road conditions, radar and other switches respectively. Moreover, because there are many radar waves of the road detection probe in the city, a higher starting speed can be set, so that the use in the urban area will not be too noisy, and running at a high speed can also give a safe reminder. Of course, the electronic dog is only an auxiliary function, and driving without speeding is an important factor for safe driving.

I am road blind and rely on navigation. "Drive to ask" is equipped with a mirror version of Gaud map. There is no doubt about the quality of Gaud in terms of map details, route planning, automatic switching between day and night modes, and route tips, which will not be repeated here. Navigation focuses on two aspects. The first is the situation of satellite search and positioning. The signal is strong and stable. There are about 11 stars in daily use.

The second is voice control. After activating with "Hello Ask", you can tell it where to go or what to do, and ask to activate navigation. Then you can directly use voice for high-speed priority, congestion avoidance, price sorting, map zooming... and other navigation operations. The experience quality is satisfactory, and the security risks brought by traditional touch operations are avoided. Next, we will use video to show voice operated navigation.

ADAS lane departure and distance early warning system is equipped on some medium and high-end models, giving a tall feeling. I am not very clear about the principle. It should be based on the front camera and radar to collect and analyze the road conditions in real time. In the actual measurement, as long as nearly half of the car body exceeds the lane line, or is too close to the car in front, the corresponding voice prompt will be given when asking, which is very useful to prevent drowsiness when running at high speed. It is suggested to add a short warning tone similar to "DidDidi" before voice prompt deviation or vehicle distance, so that the prompt effect will be more obvious.

"Experience of music, WeChat, information, telephone and other entertainment functions"

"Drive to ask" has a built-in Kuwo music player, which can not only play the music library online, but also play the local music, copy the lossless music to the TF card, and play it without obstacles. The common formats are all inclusive, and the whole process voice control is also available.

If the car audio itself supports Bluetooth, you can connect the two with Bluetooth, so that voice prompts and music can be played through the car audio, with better audio quality. My old car doesn't have Bluetooth, so I used the FM transmission function. In the test, the connection between the two is relatively stable, without noise, and the effect is also good.

We can't live without WeChat. "Drive to ask" is equipped with on-board WeChat, which can be activated by scanning the QR code on the mobile phone. Of course, the idea of using WeChat on the car is still voice. If a friend sends a message, asking will automatically broadcast the content. When replying to the content, you use voice to tell and ask, and ask will turn voice into text and send it to friends. The success rate of conversion has a lot to do with the environment in the car at that time and whether the pronunciation is standard.

When you are bored, you can also chat with "ask by car" and ask for information, such as weather, stock market, road conditions, gas stations, restaurants and other information. Intelligent speech recognition is relatively powerful, which can really realize intelligent travel.

Ask if there is dual-mode Bluetooth, which can be connected to the mobile phone Bluetooth while connecting to the car audio. When making and answering calls, there are detailed voice prompts for each step of asking, and the whole process of voice operation is enough. For example, if you want to call * * (the name in the mobile phone address book), or directly report the phone number, ask for confirmation and then dial it directly. The voice call quality is also good.

In addition, the WeChat one touch function is also practical and convenient. Friends share their addresses on WeChat, so we can directly voice navigate to them and easily receive friends.

"About the function experience that cannot be known by the wife"

"Drive to ask" is not as smart as some smart products. It requires an APP to be smart. Questioning has its own system. After binding devices in WeChat official account, it can realize location track query, monitoring, receiving, violation query, real-time traffic, picture and video browsing and other extension functions.

Among them, the position query can query the current vehicle's position, speed, and last running time. Because the GPS data is collected, it is very accurate. The track query supports viewing the driving records of vehicles within three months. There is really no place to hide, you know.

The monitoring function is to send a text message using the WeChat official account on the mobile phone, and then ask the driver to read it aloud. To extract photos and video commands, ask for instant photos or record 10 second videos, upload them to the user platform, and then extract them from the mobile WeChat terminal. Personally, I think this function can monitor the running status of the vehicle on the one hand, and also has the auxiliary function of anti-theft recovery.

The image browsing function allows offline query of the latest 50 photos uploaded to the user platform by "driving to ask", and video browsing allows you to view up to 10 short videos extracted from the query.

The vehicle license needs to be bound for violation inquiry. If you feel that you have violated the rules, you can go to inquire about it and deal with it in time to avoid the trouble of vehicle review. Real time traffic is also the map information of Gaud, which is convenient to adjust the driving plan according to the traffic flow.

At the same time, the "driving inquiry" has the parking monitoring function, and there are four levels of settings: medium, low, low and minimum. The reality of the default medium sensitivity is that when you get out of the car and close the door with a little more effort, your WeChat will receive the vehicle alarm notice, and send instant photos taken to help you judge the cause of vehicle vibration and obtain evidence, which is also an important role of asking about sleep. I suddenly thought, if the car shakes, will the mobile phone receive an alarm notification that there is no power???

Speaking of this, you can see why I call this part "functional experience that my wife cannot know". You told your wife to work overtime, but you drove to the bar to hang out with friends. The track, monitoring, pictures and videos you asked for were all recorded···

In short, the use of "driving to ask" during this period has brought me many surprises and convenience. In appearance, the design and material are excellent, the workmanship and details are good, the screen is clear, and the volume control is ideal, which will not block the driving line of sight. In terms of installation, there are many third-party cooperative stores, which can be replaced by themselves. The installation service is up to standard and considerate. In terms of functions, there are not only conventional three treasures of driving, such as tachograph, electronic dog and Gaode navigation, but also entertainment functions such as music, WeChat, telephone, inquiry and consultation, as well as black technologies such as lane departure and distance early warning, and security functions such as vehicle location, driving track, parking monitoring, remote control, etc. In particular, all these functions can be realized through voice, The accuracy and response speed of speech recognition is also the best among many brands.

Technology really changes the world. I'm looking forward to the future journey of automatic driving when I get on the bus and say "destination".
