Chassis domain controller, system and method of automobile

Abstract

The invention provides a chassis domain controller, system and method of an automobile. The chassis domain controller is used for obtaining automobile state parameters detected by a plurality of sensors of an automobile, generating a control instruction according to the automobile state parameters and sending the automobile state parameters and the control instruction to corresponding electronic control units in the function control units connected with the sensors so as to adjust the state of the automobile. In this manner, the chassis domain controller can uniformly obtain automobile state parameters; according to requirements of each electronic control unit in the function control unit, the corresponding automobile state parameters and the generated control instruction are sent to the corresponding electronic control unit; the problem that when multiple electronic control units in the function control unit independently adjust the state of the automobile, the automobile state parameters are repeatedly obtained, the corresponding states of the automobile are resolved, and consequently computing resources are wasted is solved, and a large number of resources can be saved under thecondition that the control precision and the control effect of the automobile are guaranteed.

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
