3、 Multimedia configuration test link

In terms of USB interface in the car, the front row of the evaluation car is equipped with two USB Type-C interfaces, both located in front of the front armrest box; The rear row is also equipped with two USB Type-C interfaces, which are located below the air outlet of the air conditioner. The vehicle is equipped with a 12V power interface, which is located in front of the front armrest box. In addition, we tested the voltage and current of USB interface. Although the test results fluctuated slightly, all interfaces could reach about 5V and 1.9A.

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

According to the actual measurement, the intelligent voice system of the evaluation car can recognize "I'm a little cold/I'm a little hot", "I want to listen to 'XXXX' (song name)" and "I want to go to Lunyang Building", and operate the above functions, but can not achieve the operation of "open the window/open the driver's window/open the sunroof". At the same time, the driver can wake up just by saying "Hello, Volkswagen". The car engine system also supports user-defined wake-up words. In addition, there are keys on the right side of the steering wheel, which can also wake up the voice system.
