Title:
CONTROL METHOD FOR ELECTRIC VEHICLE AND CONTROLLER
Document Type and Number:
Japanese Patent JP2019103249
Kind Code:
A
Abstract:
To suppress output of an excess vibration suppression compensation value from an F/B compensator, even when a drive brake force is input individually from each motors respectively provided on left and right drive wheels.SOLUTION: A vibration control is executed to each of a plurality of motors. In the vibration control, a filter for estimating a rotation angle speed of the motor using a vehicle model simulating transfer characteristics from an input of a torque command value to the motor to rotation angle speed of the motor, the filter being formed of a reverse characteristic of a vehicle model and band pass filter, is used. When a drive brake torque of the second motor is input to the vehicle, a filter of a transfer function from input of the drive brake torque of the second motor to rotation angle speed of the first motor is used for correcting an estimated value of the rotation angle speed of the first motor.SELECTED DRAWING: Figure 1
