The invention relates to the field of electric vehicles, in particular to a crawling control method for a pure electric heavy truck with high adaptability. According to the method, after the pure electric heavy truck enters a crawling function, P-item dynamic proportional control is carried out, and P-item dynamic proportional control torque is obtained; performing I-item dynamic integral proportional closed-loop control to obtain an I-item dynamic proportional integral closed-loop regulation control torque; gradient feed-forward torque compensation control is carried out, and gradient compensation torque is obtained; vehicle weight feed-forward torque compensation control is carried out, and vehicle weight compensation torque is obtained; and the P-item dynamic proportional control torque, the I-item dynamic proportional integral closed-loop adjustment control torque, the slope compensation torque and the vehicle weight compensation torque are added together to obtain a crawling closed-loop adjustment control torque, fixed limit value processing is conducted on the crawling closed-loop adjustment control torque, and the situation that abnormal torque is output due to closed-loop adjustment is prevented. By means of the method, stable crawling speed control over the pure electric heavy truck can be achieved under the conditions of no hanging, hanging, no load, full load and different slopes.
本发明涉及电动车领域，涉及一种具有高适应性的纯电动重卡蠕行控制方法。该方法在纯电动重卡车辆进入蠕行功能后，进行P项动态比例控制，获得P项动态比例控制扭矩；进行I项动态积分比例闭环控制，获得I项动态比例积分闭环调节控制扭矩；进行坡度前馈扭矩补偿控制，获得坡度补偿扭矩；进行车重前馈扭矩补偿控制，获得车重补偿扭矩；将P项动态比例控制扭矩、I项动态比例积分闭环调节控制扭矩、坡度补偿扭矩、车重补偿扭矩相加，得到蠕行闭环调节控制扭矩，对蠕行闭环调节控制扭矩进行固定限值处理，防止闭环调节导致输出异常扭矩。通过本发明方法，纯电动重卡车辆未带挂、带挂、空载、满载以及处于不同坡度条件下都能实现稳定的蠕行车速控制。
