If the amount of depression of the accelerator pedal is increased, the speed of the dump truck 2 is increased, and the amount of fuel consumption is increased accordingly. On the other hand, when performing constant speed operation or deceleration, fuel consumption can be saved.
- the dump truck 2 can save more fuel when operated at a constant speed than when it is repeatedly decelerated. Therefore, when the operator actually operates the dump truck 2 from the data shown in FIG. 5 by appropriately setting the constant speed operation section, the acceleration section and the deceleration section based on the terrain of the traveling road. In addition, fuel efficiency is high, and it is efficient, driving stability is ensured, and operation management with good operability can be performed.
