Automobile electronic control system and automobile

Abstract

The invention discloses an automobile electronic control system and an automobile. The framework comprises a vehicle-mounted ethernet network, multiple sensors, multiple data concentration units and multiple domain controller processing units. The vehicle-mounted ethernet network comprises a backbone network bus arranged in an automobile body. The sensors are distributed at different positions ofthe automobile body. The data concentration units are each connected with the backbone network bus. Each data concentration unit is connected with at least one sensor. The multiple domain controller processing units are each connected with the backbone network bus. The multiple domain controller processing units conduct automatic drive movement control on the automobile body according to perception data of a sensor in the backbone network bus. Connection of the multiple sensors and wire harness arrangement of vehicles are simplified.

Description

technical field [0001] The present invention relates to the technical field of self-driving cars, and more specifically, to a car electronic control system and a car using the car electronic control system. Background technique [0002] At present, self-driving cars need to be connected to many different sensors. The amount of data that self-driving cars need to process is large, and the algorithms are also very complex. Therefore, the computing power of self-driving cars is very demanding. The safety level required by different functions is also different. For example, the related functions of the smart cockpit have little to do with the safe driving of the car. Therefore, the safety level of the smart cockpit is correspondingly lower; the related functions of automatic driving are very related to the safe driving of the car. The security level of software and hardware related to autonomous driving is much higher. The division of functional safety levels refers to the ISO2...
