摘要： A vehicle vibration suppression control device includes: a first torque target value calculation unit that inputs a motor torque instruction value and that uses a previously modeled transmission characteristic of the vehicle to calculate a first torque target value; a second torque target value calculation unit that includes a filter having a characteristic of a model H(s)/Gp(s) formed with a model Gp(s) of a transmission characteristic of a torque input to the vehicle and a motor angular velocity and a bandpass filter H(s) in which a frequency in the vicinity of a torsional vibration frequency in the vehicle is a center frequency, that inputs a deviation between a detection value of the vehicle state amount and an estimation value of the vehicle state amount and that calculates a second torque target value; and a motor torque control unit that controls a motor torque according to a final torque target value obtained by adding the first torque target value and the second torque target value. The vehicle state amount is estimated based on the first torque target value on which the lag processing has been performed and the second torque target value.

摘要： The control device for the electric vehicle determines whether or not the starting operation of the vehicle has been performed by the driver, calculates the disturbance torque estimated value Td necessary for maintaining the vehicle stop state corresponding to the disturbance acting on the vehicle, and performs a control such that the driving torque of the motor converges to the disturbance torque estimated value Td when the vehicle is determined to be just before stop of the vehicle during running or determined to have undergone the starting operation. Then, the control device for the electric vehicle controls the responsiveness of the driving torque to the disturbance acting on the vehicle, and increases the responsiveness of the driving torque of the motor compared with the responsiveness of the driving torque just before stop of the vehicle when the starting operation is determined to have been performed.
