Abstract:
The control method for an electric vehicle sets a motor torque command value based on vehicle information and controls torque of a first motor connected to a first drive wheel which is one of a front drive wheel and a rear drive wheel. The control method for an electric vehicle calculates a first torque command value by a feedforward computation based on the motor torque command value, detects a rotation angular velocity of the first motor, and estimates a rotation angular velocity of the first motor based on the first torque command value by using a vehicle model Gp(s) that simulates a transfer characteristic from a torque input to the first drive wheel to a rotation angular velocity of the first motor.
