Title:
CONTROL DEVICE FOR ELECTRIC VEHICLE
Document Type and Number:
Japanese Patent JP3831264
Kind Code:
B2
Abstract:
PROBLEM TO BE SOLVED: To obtain a sufficient vibration control effect, even if the resonance frequency of a drive system is near the cut-off frequency of a motor-current control system.
SOLUTION: Advance compensation is conducted for compensating the response delay of the motor-current control system for vibration compensating torque that controls the resonance of the drive system of an automobile, and the vibration compensating torque, after the advance compensation, is added to a motor-torque command value, to correct the command value. A motor- current command value, corresponding to the motor-torque command value after the compensation, is then calculated, and current control is performed so that the current flowing to a motor matches the motor-current command value.
