Embodiment 1
[0065] like figure 1 and 2 As shown, the embodiments of this specification provide a chassis control method based on a chassis control domain system, the chassis control domain system is used to coordinately control the actuators of the vehicle chassis to adjust the operating conditions of the vehicle, wherein the actuators include a motor , a braking system, a steering system, a suspension system and an active headlight system, the method comprising:
[0066] S100: Receive request information from the advanced driving assistance system;
[0067] In this embodiment, a chassis control domain system based on the advanced assisted driving function is established, which can also be called a lower-layer control domain system. By receiving different function requests with upper-layer control information sent by ADAS, the chassis control domain system is unified and coordinated to control it. As the lower control domain system of the advanced assisted driving domain system, it unif...

The invention relates to a chassis control method and system based on a chassis control domain system. The method comprises the steps that request information of an advanced driving assistance system is received; acquiring current vehicle state information; obtaining vehicle state adjustment information according to the request information and the vehicle state information; determining a corresponding target control algorithm according to the vehicle state adjustment information, wherein the target control algorithm comprises a longitudinal control algorithm, a transverse control algorithm and a vertical control algorithm; obtaining a corresponding target function control request based on the target control algorithm according to the vehicle state adjustment information; and sending the target function control request to a target actuator of the vehicle chassis to control the target actuator to adjust the operation condition of the vehicle. Different target control algorithms are adopted according to different function requests, control over different actuators is achieved, and the reaction efficiency of the actuators is improved; the technical problem that the control effects of a plurality of actuators of a chassis in the prior art are not easy to effectively unify and coordinate is solved.
Description
technical field [0001] The present invention relates to the technical field of chassis, in particular to a chassis control method and system based on a chassis control domain system. Background technique [0002] At present, advanced assisted driving functions, such as ACC (adaptive cruise), APA (automatic parking) and other advanced assisted driving functions, are perceived by the upper layer of ADAS (advanced driver assistance system) according to the environment, vehicle status, vision, radar sensors, etc. Decision-making and planning, and finally, according to different functions, send relevant acceleration, deceleration, steering and other commands to each actuator of the lower chassis, such as sending corner commands to the steering system, and sending acceleration / deceleration to the VCU (vehicle controller), VCU receives the Corresponding acceleration / deceleration, after receiving the acceleration through different functions, different algorithms calculate the requir...
