FUZZY ADAPTIVE CONTROL SUSPENSION SYSTEM FOR A VEHICLE

摘要

The present invention further comprises a height sensor for detecting displacement of the vehicle damper, and adjusts the damping force of the variable damper according to the signal of the height sensor and the detection signals of the steering angle sensor, the TPS, the vehicle speed sensor, and the longitudinal acceleration sensor, thereby providing a ride comfort and The present invention relates to a fuzzy adaptive control suspension device for a vehicle capable of improving steering stability, comprising: a steering angle sensor for detecting a steering angular velocity of a vehicle, a TPS for detecting an engine throttle opening angle, a vehicle speed sensor for detecting a vehicle speed, and a vehicle A brake switch for detecting braking, a longitudinal acceleration sensor for detecting acceleration in the up and down direction of the vehicle, a garage sensor for detecting the displacement speed of the damper, a detection signal and a switching signal output from the sensor and the switch, and each wheel An electronic controller for outputting an actuator drive signal for appropriately adjusting the damping force of the variable damper of It consists of an actuator driven according to the drive signal output from the controller, in the electronic controller additionally configured to the height sensor, switch the drive mode of the actuator according to the detection signals of the steering angle sensor, TPS, vehicle speed sensor and longitudinal acceleration sensor and the garage sensor, According to the normal operation check function divided into the front wheel actuator and the rear wheel actuator, there is an effect of improving the riding comfort and steering stability of the vehicle.
