The invention discloses a drive-by-wire chassis domain control system which comprises a sensing planning unit, a chassis domain controller and an execution unit. The sensing planning unit and the execution unit are both connected with the chassis domain controller; the sensing planning unit comprises an unmanned driving domain controller, a state sensing unit and a USERCAN module; wherein the state sensing unit is used for collecting road state information and sending the road state information to the unmanned driving domain controller; the chassis domain controller carries out CAN bus communication with the unmanned driving domain controller through the USERCAN module, and then the chassis domain controller carries out unified processing and recoding and then issues the information to the execution unit; according to the invention, cooperative control, control parameter redefinition and meticulous safety verification mechanism setting are carried out on parts such as drive-by-wire, brake-by-wire, steering-by-wire and gear-by-wire of the automobile chassis, so that the safety and scene expansibility of the drive-by-wire chassis domain control system are greatly improved.
本发明公开了一种线控底盘域控系统,包括感知规划单元、底盘域控制器及执行单元;感知规划单元和执行单元均与底盘域控制器连接;感知规划单元包括无人驾驶域控制器、状态感知单元和USERCAN模块;其中,状态感知单元用于采集道路状态信息并发送给无人驾驶域控制器;底盘域控制器通过USERCAN模块与无人驾驶域控制器进行CAN总线通信,再经过统一处理重新编码后下发到执行单元;本发明针对汽车底盘的线控驱动、线控制动、线控转向、线控挡位等部件进行协同控制、控制参数重定义和设立缜密的安全校验机制,大大提升了线控底盘域控系统的安全性和场景拓展性。
