Zusammenfassung:	PROBLEM TO BE SOLVED: To climb over a level difference without causing a driver to increase an accelerator angle when a vehicle approaches the level difference by supplying a motor an amount of current larger than the amount of current at the time of normal operation to when the driving speed of the vehicle is equal to or less than a reference value in spite of operation of an accelerator. SOLUTION: A drive control mechanism 1 decelerates the speed of a vehicle although a fork lift approaches a level difference and a driver keeps stepping on an accelerator 2. The speed is stored at a ROM 11 and the amount of motor current automatically increases when the speed is equal to or more than a preset reference value, thus causing the motor current to immediately increase when the fork lift approaches the level difference and cannot move and hence eliminating the need for the driver to deeply step on the accelerator 2 and enabling the form lift to climb over the level difference.
