1.17 From mid to high-end in car infotainment systems
Leiditech recommends protective devices and solutions for in car infotainment systems
Vehicle interface processor: mainly responsible for power management, network, starting the Application Processor, monitoring the stable operation of the system (including temperature monitoring and voltage monitoring), fault diagnosis information, offline detection, etc.
The in car infotainment system mainly consists of three parts: vehicle interface processor, application processor, and remote information processor.
The remote information processor, the onboard T-BOX, communicates with the host through canbus to transmit instructions and information, including vehicle status information, button status information, control instructions, etc; Through audio connection, both parties can share microphone and speaker output.
The application processor is mainly responsible for the entertainment system part, body part function control, body information display, driving safety monitoring, etc.
Industry hotspots:The Vehicle-to-everything is the future development trend of the on-board information and entertainment system. The Vehicle-to-everything needs to obtain data in the internal and external communication channels of the vehicle, access and collect messages from the communication network, so as to improve the on-board Big data system. At present, the vehicle communication network includes Ethernet, CAN bus, LIN bus, and flexray bus.
