PROBLEM TO BE SOLVED: To provide a travel control technology which can correct the speed difference between the left and right wheels, which is caused by an internal factor produced by the road surface state and caused by human factors produced by braking, only when corrections are necessary, while normal forward moving, reverse moving and left and right revolving operations are maintained. SOLUTION: Revolutions of the left and right electric motors are controlled equal to each other, only when the opening rates of left and right brakes are identical or approximately equal to each other by carrying out steps ST12-ST21. With such a constitution, the forward traveling performance of a motor-driven vehicle will not be influenced by a road surface state, etc., and can be improved. Since higher revolution is adjusted to the lower revolution, even if one side driving wheel runs on the unevenness of a road surface, a slope, etc., a body can be stabilized more by lowering the speed. |
