Claim Text:
1. A device for controlling an electric vehicle that is configured to set a motor torque instruction value based on vehicle information and control a torque of a motor connected to a drive wheel, the device comprising: a feedforward computation unit that is configured to input the motor torque instruction value without inputting a detection value of a sensor provided in the electric vehicle and compute a first torque target value by feedforward computation; and a motor torque control unit that is configured to control the motor torque according to the first torque target value, wherein the feedforward computation unit includes: a vehicle model which is configured to input the motor torque instruction value to model a characteristic from the motor torque to a drive shaft torsional angular velocity; and a drive shaft torsional angular velocity feedback model which is configured to feed back the drive shaft torsional angular velocity output from the vehicle model to the motor torque instruction value to compute the first torque target value.
