Title:

MOTOR VIBRATION DAMPING CONTROLLER FOR ELECTRIC VEHICLE

Document Type and Number:

Japanese Patent JP2015043669

Kind Code:

A

Abstract:

PROBLEM TO BE SOLVED: To reduce vibration at the time of releasing park lock.SOLUTION: A control block 48 outputs a second torque target value by applying a filter process to an output value of a subtracter 47, in other words, a value obtained by subtracting a second clause of a second torque target value from a first clause of the second torque target value. Here, a frequency characteristic of a transmission characteristic Gz(s) of the control block 48 has a frequency characteristic of which attenuation amount is smaller when compared with a case in which a wheel is in no-lock state, at the time when a park lock state is released.
