3、 Multimedia configuration test link

In terms of USB interfaces in the car, the evaluation car is equipped with 4 USB interfaces. The front row has two USB Type-C interfaces, and the rear row has one USB Type-A and one USB Type-C interface. At the same time, two 12V power interfaces are provided in the car, which are located below the front central channel and on the right side of the rear compartment.

In addition, we tested the voltage and current of the USB interface. The two USB Type-C interfaces in the front row are divided into charging interface and data interface. The former can reach about 9V voltage and 0.7A current; The voltage of the latter is about 5V, and the current is about 1.5A, which is basically the same as the data of the rear charging interface.

With the increasing popularity of intelligent car machines, more and more cars are equipped with intelligent voice assistants. For "intelligent voice system", we will judge the performance of voice interaction system in terms of voice recognition rate, response speed and controllable functions through the following four fixed scripts.

1. I'm a little cold/I'm a little hot

2. Open the window/open the driver's window/open the sunroof

3. I want to listen to "XXXX" (song name)

4. I'm going to Lunyang Mansion

After actual measurement, when you say "Hello smart", the intelligent voice system will wake up, and all the above commands can be recognized and completed. It should be noted that the system only supports the control of double sound zones in the front row, and the music APP requires a login member to play songs on demand normally.
