A method of controlling an electronic driving motor for driving a vehicle by controlling the force between a drive wheel and a rail on which the vehicle travels comprising the steps of: (a) monitoring the relative velocity of the periphery of said drive wheel with respect to the velocity of said vehicle and generating a first signal representative of said relative velocity; (b) generating a second signal representative of the rate of change of said relative velocity as represented by said first signal; (c) monitoring the rate of change of force acting between said driving wheel and said rail and generating a third signal representative thereof; (d) in response to the polarity of the rate of change of relative velocity as represented by said second signal differing from the polarity of the rate of change of force acting between said driving wheel and said rail as represented by said third signal, generating a fourth signal for decreasing the force between said driving wheel and said rail. A method of controlling an electric driving motor in a vehicle for driving rolling stock having first means for controlling the force acting between a wheel and a rail in accordance with a current reference signal generated on the basis of an instruction, second means for detecting the difference between a peripheral velocity of the wheel and vehicle velocity, third means for discriminating an unallowable nonadhesive state of running of the wheel when the velocity difference detected by the second means exceeds a certain value to generate a compensating signal for decreasing the value of the current reference signal applied to the first means so that the force acting between the wheel and the rail is reduced; wherein the compensating signal is obtained by the following steps: calculating the rate of change of the velocity difference with respect to time; calculating the rate of change of the force acting between the wheel and the rail with respect to time; and generating said compensating signal for decreasing the current reference when the polarity of the rate of change of the relative velocity is different from that of the rate of change of the force acting between the wheel and the rail.
