[0046] Specifically, the MCU 11 is used to send configuration word information to the first SOC 12, the first SOC 12 is used to parse the configuration word information to generate attribute information, the first SOC 12 determines that the peripheral device corresponding to the attribute information is the automatic parking system 3, the first SOC 12 controls the deserializer 15 to load the driver configuration of the automatic parking system 3, the deserializer 15 is used to load the driver configuration of the automatic parking system 3, and sends a handshake signal to the second serializer 31 corresponding to the automatic parking system 3 to establish communication between the vehicle computer 1 and the automatic parking system 3, so as to facilitate the automatic parking system 3 and the vehicle computer 1 to transmit information of data flow and control flow.

[0047] Specifically, the MCU 11 is used to send configuration word information to the first SOC 12, the first SOC 12 is used to parse the configuration word information to generate attribute information, the first SOC 12 determines that the peripheral device corresponding to the attribute information is the reversing image camera 2, the first SOC 12 controls the deserializer 15 to load the driver configuration of the reversing image camera 2, the deserializer 15 is used to load the driver configuration of the reversing image camera 2, and sends a handshake signal to the first serializer 21 corresponding to the reversing image camera 2 to establish communication between the vehicle computer 1 and the reversing image camera 2, so as to facilitate the reversing image camera 2 and the vehicle computer 1 to transmit information of data stream and control stream.

The deserializer is connected to the male terminal, and the male terminal is connected to the female terminal through GMSL (the pin 1-ANT of the male terminal is connected to the 1-ANT of the female terminal. For the car machine, the 1-ANT of the female terminal is the input IN of the GMSL), and the female terminal is connected to the second serializer. Among them, the male terminal is the one on the car machine, and the female terminal can be on the APA or on the RVC.

At this time, the vehicle computer does not need to power the device, and the COAX terminal 1 pin (pin 1-ANT of the male terminal is connected to 1-ANT of the female terminal. For the vehicle computer, 1-ANT of the female terminal is the input IN of GMSL) on the vehicle computer side can be directly connected to the IN sent by APA. However, when the peripheral device is RVC, the second video stream of the RVC camera needs to be transmitted to the vehicle computer through COAX, but at the same time the camera needs COAX to power it. At this time, the vehicle computer provides the 8V power required by the camera. The circuit is filtered by the series inductor component, and the three capacitors also play a filtering role to filter out the high-frequency noise and interference in the power supply transmitted by APA and RVC, which is given from pin 1-ANT of the COAX terminal, while receiving the IN signal sent by RVC.

In the technical solution provided by the embodiment of the present invention, the same deserializer and vehicle computer interface can adapt to a variety of peripheral devices, reducing the material cost of the vehicle computer interface.

[0054] Based on the above vehicle control system, an embodiment of the present invention provides a vehicle control method. Figure 6 A flow chart of a vehicle control method provided by an embodiment of the present invention, such as Figure 6 As shown, the method includes:

In the technical solution provided by the embodiment of the present invention, the same deserializer and vehicle computer interface can adapt to a variety of peripheral devices, reducing the material cost of the vehicle computer interface.

[0067] The technical solution provided in the embodiment of the present invention solves the problem that RVC and APA need to be separately accumulated to adapt to different vehicle configurations in the design of the vehicle computer hardware module, and realizes a module design that can couple two functions to adapt to different vehicle models, saving the circuit board space of the vehicle computer and the cost of the vehicle computer's components such as deserializers and terminals, thereby generating positive benefits for the company in reducing costs and increasing efficiency.
