The invention discloses a control method for an electric wheel dump truck under an idle downhill working condition. When the electric wheel dump truck is in the idle working condition, preset brakingtorque is applied to the electric wheel dump truck so as to increase the intermediate voltage of a main circuit when the electric wheel dump truck runs on a bumpy downhill road section, and the stability of the intermediate voltage is maintained through a chopper circuit of the main circuit of the electric wheel dump truck; or when the electric wheel dump truck is in the idle working condition, the preset traction moment is applied to the electric wheel dump truck so as to counteract the braking energy of the electric wheel dump truck when the electric wheel dump truck runs on a bumpy downhillroad section, and the stability of the intermediate voltage of the main circuit is maintained. The control method of the electric wheel dump truck under the idle downhill working condition has the advantages of being easy and convenient to operate, stable in intermediate voltage, safe and reliable in whole truck running and the like.
本发明公开了一种电动轮自卸车惰行下坡工况下的控制方法,在电动轮自卸车处于惰行工况时,对电动轮自卸车施加预设制动力矩,以抬升电动轮自卸车在崎岖不平的下坡路段行驶时主电路的中间电压,并通过电动轮自卸车主电路的斩波电路维持中间电压的稳定性;或者在电动轮自卸车处于惰行工况时,对电动轮自卸车施加预设牵引力矩,以抵消电动轮自卸车在崎岖不平的下坡路段行驶时的制动能量,维持主电路的中间电压的稳定性。本发明的电动轮自卸车惰行下坡工况下的控制方法具有操作简便、中间电压稳定、整车运行安全可靠等优点。
