The invention discloses a crawling torque control method, device and equipment for a vehicle, and the method comprises the steps: determining the basic crawling torque of the vehicle according to the obtained current speed of the vehicle and the slope of a road surface where the vehicle is located; the current brake pressure of a brake pedal is obtained; if the current brake pressure is within a target brake pressure range, the basic crawling torque is attenuated according to a first attenuation strategy, otherwise, the basic crawling torque is attenuated according to a second attenuation strategy, the target brake pressure range represents that the deviation between the forward resistance of the vehicle and the crawling torque of the vehicle is smaller than a preset deviation threshold value, and the target brake pressure range represents that the deviation between the forward resistance of the vehicle and the crawling torque of the vehicle is smaller than the preset deviation threshold value. The torque attenuation amount correspondingly generated by the second attenuation strategy is smaller than the torque attenuation amount correspondingly generated by the first attenuation strategy. The technical problem that the shaking time of vehicle starting is long is solved.
本发明公开了一种车辆的蠕行扭矩控制方法、装置及设备,该方法包括:根据获取的车辆的当前车速和所在路面坡度,确定车辆的基础蠕行扭矩;获取制动踏板的当前制动压力;若当前制动压力处于目标制动压力范围,按照第一衰减策略对基础蠕行扭矩进行衰减,否则,按照第二衰减策略对基础蠕行扭矩进行衰减,目标制动压力范围表征车辆的前进阻力和车辆的蠕行扭矩的偏差小于预设偏差阈值,第二衰减策略对应产生的扭矩衰减量小于第一衰减策略对应产生的扭矩衰减量。通过本发明解决了车辆起步的抖动时间长的技术问题。
