A control device for a travel motor mounted to a vehicle has a resolver which works as a rotation-angle sensor. The control device has a RDC which calculates a rotation-angle output value φ based on rotation detection signals Sa, Sb transferred from the resolver. The control device supplies electric power to the travel motor based on the rotation angle output value φ. The RDC calculates “sin(θ−φ)” as an error deviation ε based on the signals Sa and Sb and the rotation-angle output value φ. The RDC calculates an angular acceleration by multiplying the error deviation ε with a gain (=Ka·Kb), and integrates the angular acceleration two times in order to obtain a next rotation-angle output value. A gain control part of the RDC decreases the gain when the judgment means judges that the travel motor rotates at a constant rotation speed.

A traction control system that combines torque sensors with wheel speed sensors and a transmission gear with vehicle speed to help sustain maximum traction. The torque sensors generate torque value as output and the speed sensors detect the wheel speed with respect to each wheel of the vehicle. An electronic control module can be utilized to detect traction loss by analyzing the torque and the speed signals and recording the applied torque value when the traction is lost. The torque value can then be limited to a value that is immediately below the recorded torque value in order to prevent further traction loss. The system monitors traction until the speed attains a steady state in order to allow maximum torque and, therefore, maximum acceleration.
