Abstract
Two motor sensors are disposed at two different angular positions of the motor to generate two pulse signals of different phases. The motor rotational speed and direction can be detected on the basis of these two pulse signals. The detected motor rotational direction is checked as to whether it is the same or opposite to that determined by the shift lever. If opposite, the battery car is determined to be being caused to move down on a sloping road, and the motor torque is corrected so that the battery car can be once stopped on condition that the accelerator pedal is slightly depressed. After that, when the accelerator pedal is further depressed and the accelerator pedal stroke reaches a stroke enough to generate a motor torque for starting the battery car on a sloping road, the ordinary drive control is executed. Therefore, the start and slow speed drive on a sloping road can be facilitated, without any skill, thus lightening the burden on the driver that the driver must depress both the accelerator and brake pedals frequently.
