The highly complex electrical and electronic architecture results in the complexity and high cost of the entire vehicle today. Even the insecurity of the car is at stake. After the popularization of intelligence in the foreseeable future, the requirements of the domain controller for data transmission will fully Ethernet the next generation of vehicles, optimize the wiring harness connection of actuators, sensors and controllers, and reduce the length and usage of wiring harnesses. Among them, the new energy pure electric vehicle represented by Tesla, through the practice of integrating the controller, promotes the concept of using the Zone Control area controller, reduces the number of functional controllers and actuators, and optimizes the connection between the controller and the actuator. , the amount of wires in the whole vehicle will be drastically reduced, the cost of the wiring harness will be greatly reduced, and the wire length of the whole vehicle is only about 2400m on the new-generation Model Y model. The length of the wire harness of the class car is as high as 6000m, and the lightweight effect of the wire is obvious. Figure 1 shows the evolution trend of the automotive electronic and electrical architecture divided by Bosch.
