<p>PURPOSE:To run a body with a speed corresponding to the operational amount of an accelerator lever or the like by regulating power supply to a motor in the direction for reducing the difference between a set speed and an actual traveling speed when a difference higher than a set value is detected through comparison. CONSTITUTION:Upon driving of a motor 7, traveling speed is determined based on a signal provided from a sensor 16 and a judgment is made whether the difference between thus determined traveling speed and a target speed is higher than a set value. If the difference is higher than the set value, a parameter corresponding to the difference is set. The operation is repeated until it is reset. Consequently, if the load increases to cause speed drop in case of hill climbing, for example, the value of parameter increases to increase power to be fed to the motor 7.</p> |
