With the growing maturity of mobile intelligent platforms, many products have also put on the cloak of "intelligent hardware", and use mobile phones as the "command and remote control center" around them. Among these products, there are only a few who can make up for the number. Although few of them are good at "color and art", they also have their own characteristics. Among them, the automobile industry has been rising in recent years, and its ownership has already "flown into the homes of ordinary people". Although most cars have built-in "smart navigation" or directly attach smart phones, it is not convenient to operate, and it also affects normal driving when driving, with poor safety. If there is an intelligent hardware, it can be connected to the intelligent platform and conveniently hung between the steering wheels. Whether it is navigation, music, phone or voice, it doesn't need to click back and forth with the arm, just move the finger gently. Its convenience goes without saying. This is the case with the main character of this article, Yilian Fangkong Intelligent Safe Driving Assistant. Let's take a look at its performance:

The package is very small, and the product effect picture in the front and middle of the white background is quite conspicuous.

As can be seen from the back of the packaging box, its hardware adopts the most common and power saving Bluetooth 4.0, and has a button battery for power supply (it can be used continuously for half a year/press 100 keys per day). At the same time, it supports IOS (above iPhone 4S) and Android (above Android 4.3) platforms, and is attached with downloadable APP and public account QR code.

After opening the package, you can see the product body, instructions and the attached button battery.

It is worth mentioning that the product evaluated this time is an engineering prototype (written in the manual), and the front of the entire product is a round rectangle five dimensional key. Different versions can be distinguished according to the color of the outermost circle (I am red, and there is a blue version). There are blue, green, red and yellow dots on the corners of the four keys, but they are printed, not indicators. The key feedback is good, but because the key logic has different functions in different applications (music, navigation, phone, etc.), you need to play/operate repeatedly for the first time.

The battery is a Panasonic CR2032 button battery, which should be easy to buy.

It is very convenient to open the battery. You just need to pull out the battery compartment cover at the back clamping position. However, during installation, remember to place the positive pole of the battery downward in the battery slot, and then fasten the snap.

There are anti-skid grooves on the inner side of the strap, and there are many buttonholes, which can be firmly fastened to the steering wheel. Let's take a picture (my model is a picture of Hyundai):

Next, we will focus on the compatibility of the connection between the safety driving assistant and the smart phone, and the perfection and functional practicability of the APP. My mobile phone is Le MAX (customized version of Android 5.0). After downloading the APP, I will automatically turn on Bluetooth, click "Hardware Connection", and search in N seconds. When you open it for the first time, you can see its function introduction: 1 second song cut, phone call, navigation, road condition check:

The main interface is a horizontal screen, and its function modules are displayed in a grid way, which is roughly similar to the general navigation software. To save traffic, you can download offline maps in advance, sign in (give points), and check the mileage (my footprint):

The three function items on the left side of the interface are function main interface, music/navigation interface and voice query interface. Let's take a look at them:

The music/navigation interface can be very intuitive to view the current driving section, and can set common addresses (such as home, company, etc.), control the music (with the hardware side), and make calls (turning pages, looking for contacts, etc.).

The navigation can set common addresses such as home address, company address, and history query:

This app also has a simple interactive ranking function, such as viewing the ranking of users' driving mileage.

The built-in voice assistant can voice find the corresponding location, call someone, and control the playing of music. Recognition is just so so. During the use of APP, there is no flash back, restart and other phenomena. The compatibility is acceptable, and the interface is relatively simple and generous. The hardware control is also quite good.

Conclusion: Judging from the use in recent years, Yilian Fangkong Intelligent Safe Driving Assistant is generally satisfactory, which can alleviate the dependence on mobile phones in driving to a certain extent, and improve driving safety and convenience. However, since it is its first product, it needs more polishing in details, such as improving the accuracy of speech recognition, adding key indicators, optimizing function logic, and making it easier for users to control. In a word, flaws do not cover up weaknesses. If you need a simple and easy to use little assistant, it is a good choice.
