摘要： A device for controlling the D.C. drive motor of a battery powered motor vehicle having an on-board storage battery, which motor has an armature and a separately excited field winding. This control device includes means for sensing the current flow (122) through the armature, means for creating an armature current signal indicative of the sensed armature current (124), means for creating a reference signal indicative of a desired speed of the vehicle (110), comparison means for creating an error signal indicative of the relationship between the armature current signal and the reference signal (120), means for controlling the voltage applied across the armature in accordance with the error signal (140) and means responsive to the error signal for varying the voltage across the field winding in accordance with the error signal when the error signal exceeds a preselected value (172). In this device there is provided an improvement including means for controlling the voltage across the field winding in accordance with the reference signal at least during a period that the error signal is below a preselected value. In this manner, the voltage applied across the field winding of the control device is controlled by the reference signal such as created by the position of the acceleration pedal in the motor vehicle.
