Abstract

The invention discloses a multifunctional automobile control system which comprises a control unit. The signal input end of the control unit is connected with a wheel speed sensor, a steering wheel rotating angle sensor, a transverse deflection rate sensor, an ignition switch, a brake switch and an ASR / ESP switch. The first control output end of the control unit is connected with an engine control unit through a CAN bus and used for controlling an electronic throttle through the engine control unit. The second control output end of the control unit is connected with a hydraulic control unit and controls all electromagnetic valves and an oil return pump in the hydraulic control unit. The multifunctional automobile control system integrates the functions of systems such as the ABS, the ASR and the ESP, the braking performance and running stability and safety of an automobile can be greatly improved, the structure and the control principle are simple, the integration of execution elements is high, and the cost is low.

Description

technical field [0001] The invention relates to a multifunctional vehicle control system. Background technique [0002] Automotive ABS is an active safety device, which can prevent the wheels from locking up during emergency braking, shorten the braking distance, improve the directional stability and steering control ability of the vehicle during braking, and improve the driving safety of the vehicle. Automobile ASR can prevent the driving wheels from slipping during the acceleration process, so as to maintain the best driving force of the car and the stability and maneuverability of the driving direction. Car ESP can improve the driving performance of the car, it is the functional extension of ABS and ASR system. At present, automobile ABS has become the standard configuration of cars and buses, while automobile ASR and ESP are widely used in high-end cars. However, the structure and control principle of traditional automobiles are complex, and the integration of actuator...
