PURPOSE:To prevent a motor driving level from becoming unstable at the time of starting a motor-driven vehicle. CONSTITUTION:The driver for a motor-driven vehicle of the type for outputting a drive duty signal to drive a motor only when the duty signal exceeds a certain predetermined value sets the predetermined value to a level of an upper limit predetermined value 22 when the signal is in a rising step and to a level of a lower limit predetermined value 23 when the signal is in a falling step. Accordingly, since hysteresis can be set to a predetermined value, even if the signal is varied within a hysteresis region 24, a motor does not repeat starting, slipping, etc. |
