Description

technical field [0001] The present invention relates to an integrated control system of an automobile, and more particularly relates to an integrated control system of an electric automobile. Background technique [0002] The control system of the car mainly includes the front wheel steering system and the braking system. At present, the car uses a mechanical steering system and a hydraulic or pneumatic braking system. The mechanical steering system uses a mechanical connection device to connect the steering wheel with the steering wheel. When turning, the driver turns the steering wheel, and the mechanical connection device transmits the angle information of the steering wheel to the steering wheel. Because the angular transmission ratio of the mechanical steering system is fixed, and the steering characteristics of the car show a strong nonlinear time-varying characteristic with the change of vehicle speed and lateral acceleration, the control effect of the control system ...
