Recently, Google successfully applied for a patent for "bus detection". In fact, the application submission date of the patent is 2014, and it is only these days that Google has been granted the patent. The patent can accurately judge the volume and color of the bus through special image recognition technology, so as to avoid the bus.

After the crash, the person in charge of Google Unmanned Vehicles said that buses are an important means of transportation for the society. They have many passengers, including many students. It is a terrible thing to collide with a bus. Therefore, after the crash, Google's driverless department repeatedly conducted 3500 tests to detect buses.
