<p>PROBLEM TO BE SOLVED: To provide a method for drive control of a vehicle motor which can manage both a sufficient braking force and smooth stop performance on a slope and on a level ground and has high safeness. SOLUTION: When an operation force is not detected for a prescribed time or an operator is not detected, a road surface state is decided by a road surface inclination deciding means (first step). If the road surface is decided to be a level ground in the first step, a road surface inclination deciding action is switched to a speed feedback control action with a zero speed command (second step). After the second step, when a motor revolution reaches a value not larger than a prescribed revolution, the action is switched to a dynamic braking action. Or, even if the motor revolution is not smaller than the prescribed revolution, the action is switched to the dynamic braking action after a lapse of a certain time (third step). Further, a mechanical brake is put into action after a lapse of a prescribed time (fourth step).</p> |
