Classification: CPC B  Y | IPC B

Claim 7:
8. A control device of an electric vehicle using one or a plurality of motors as a traveling drive source, comprising a controller programmed to:
calculate a motor torque command value;
detect an angular velocity correlating with a rotation speed of a drive shaft which transmits a drive force of the motor to a drive wheel;
estimate a disturbance torque acting on the motor according to a difference between a first motor torque estimation value based on the angular velocity and a second motor torque estimation value based on the motor torque command value;
set a limiting torque corresponding to the disturbance torque in a manner that a slipping rate of the drive wheel does not exceed a first predetermined value; and
limit the motor torque command value using the limiting torque.
