<p>PURPOSE:To eliminate the overrunning of a motor even if an accelerator is fully opened on a descent road by controlling to divide the accelerator voltage when the accelerator is fully open and the motor has no load. CONSTITUTION:When an accelerator 1 is not fully opened, a comparator 7 becomes a low level, and when a load of the prescribed value or higher is applied to a motor M as on an ascent or flat road, a comparator 6 becomes a low level. When the comparator 6 or 7 is the low level, the output of an inverter In2 becomes a high level, and the accelerator voltage is applied to a comparator 3 as it is. When the accelerator 1 is fully opened and the motor has no load, the output of the inverter In2 becomes the low level, the output voltage of the accelerator 1 is divided by resistors r1, r2, and inputted to the comparator 3.</p> |
