    • The invention is intended to provide a downhill speed control system which employs a method of setting a target vehicle speed in advance, thereby improving controllability when a vehicle runs down a slope, and giving an operator improved operability in setting of the target vehicle speed. Brakes are controlled so that, when the vehicle runs down the slope, an actual vehicle speed is matched with a target speed set by a switch which can set the target speed by selectively or continuously changing plural preset speeds. Also, control constants for PID control are modified depending on settings of a downslope gradient setting switch and a load setting switch. When an acceleration computed from the actual vehicle speed is larger than a target acceleration, the strength of applied brake is increased.
    • 本发明旨在提供一种采用预先设定目标车速的方法的下坡速度控制系统,从而提高了当车辆向下坡度时的可控性,并且提高了操作者在设定目标车速方面的可操作性。 制动器被控制,使得当车辆沿着斜坡行驶时,实际车辆速度与由开关设置的目标速度相匹配,该开关可以通过选择性地或连续地改变多个预设速度来设定目标速度。 此外,PID控制的控制常数根据下坡梯度设置开关和负载设置开关的设置进行修改。 当从实际车速计算的加速度大于目标加速度时,施加制动器的强度增加。
