Claim 0:
1. A control method of an electric vehicle using one or a plurality of motors as a traveling drive source, comprising:
a motor torque command value calculating step comprising calculating a motor torque command value;
an angular velocity detecting step comprising detecting an angular velocity correlating with a rotation speed of a drive shaft which transmits a drive force of the motor to a drive wheel;
a disturbance torque estimating step comprising estimating 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;
a limiting torque setting step comprising setting 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
a motor torque limiting step comprising limiting the motor torque command value using the limiting torque.
