A kind of pure electric automobile eliminates the control method of vehicle shake

A kind of pure electric automobile eliminates the control method of vehicle shake, and entire car controller, by gathering accelerator pedal signal, gear signal and brake pedal signal, parses the real driving intention of driver, thus calculates operator demand's torque T qDrvReq；Electric machine controller feeds back to the motor actual speed signal MotSpd of entire car controller, and MotSpd is filtered obtaining MotSpdFil by entire car controller.By the difference of MotSpdFil Yu MotSpd, calculate correction torque T qCorr with pid algorithm, operator demand's moment of torsion is modified.Passing through, superposing of TqDrvReq with TqCorr obtains final demand torque TqReq, sends it to electric machine controller, allows it perform this moment of torsion.This method can eliminate the shake of vehicle, compared with reducing gear clearance and optimize the traditional approach of drive mechanism, has low cost, implements simple, easily checking and the advantage such as effective.
