Automotive chassis domain controller, system and method

Abstract

The present application provides an automobile chassis domain controller, system and method. The chassis domain controller is used to obtain vehicle state parameters detected by multiple sensors of the automobile, generate control instructions according to the automobile state parameters, and combine the automobile state parameters and control instructions Send it to each corresponding electronic control unit in the functional control unit connected with the sensor to adjust the state of the car. In this way, the chassis domain controller can uniformly obtain vehicle state parameters, and send the corresponding vehicle state parameters and generated control instructions to the corresponding electronic control units according to the needs of each electronic control unit in the functional control unit, avoiding functional control When multiple electronic control units in the unit independently adjust the state of the car, the problem of waste of computing resources caused by repeatedly obtaining the state parameters of the car and solving the corresponding state of the car respectively can ensure the control accuracy and control effect of the car. conditions, saving a lot of resources.

Description

technical field [0001] The present application relates to the field of automobile control, in particular, to an automobile chassis domain controller, system and method. Background technique [0002] The rapid development of self-driving cars has increasingly stringent requirements for its chassis electronic control system. In order to achieve more accurate and intelligent vehicle posture monitoring and regulation, many sensors such as wheel speed sensors are integrated in the chassis domain of the car. The chassis domain controller of the self-driving car will process the raw data collected by the sensors in the chassis domain, so that it can be applied to various advanced automatic driving functions such as the lane keeping system and the automatic parking system, and contribute to the automatic driving The underlying actuators of the car issue corresponding instructions to control the self-driving car to reach the optimal driving state at the current node.

AI Technical Summary

Problems solved by technology

After the existing chassis controllers have more and more electronic control functions in the chassis of self-driving cars and the number of ECUs increases, the cost of the corresponding controllers will increase, and each electronic control system may repeatedly read and use the same signal, and separate them in their respective ECUs. Perform vehicle state calculation and estimation, which will increase the calculation load of each underlying ECU and waste existing hardware resources
