Abstract
PURPOSE:To securely prevent a drive wheel from freely rotating by comparing a detected signal of a drive wheel rpm of a vehicle with a detected signal of a relative speed of the vehicle signal respect to the ground and by controlling a drive motor so that the drive wheel is brought into traction contact with a rail based on the comparison signal. CONSTITUTION:Employing a wheel shaft rpm detector 7 for detecting the rpm of a drive wheel 3 and a speed detector 10 of the Doppler type or the like for detecting the relative speed of a vehicle 2 with respect to the ground 11, output signals from those detectors are inputted to a processing circuit 9. When the drive wheel 3 starts to freely rotate as a result of running acceleration, etc. and a frequency difference between the rotation-detected and speed-detected signals goes beyond a certain level, the processing circuit determines that free rotation has occurred. In that case, current to a drive motor 5 is controlled to be reduced via a motor control circuit 6. This causes the drive torque of the drive motor 5 to be reduced to bring the drive wheel 3 again into traction contact with a rail 1 and to prevent free rotation.
