The invention discloses a vehicle output torque control method. The control method comprises the following steps: obtaining the acceleration of vehicle driving; if the running acceleration of the vehicle is changed, judging whether a backlash exists between a driven transmission gear and a driving transmission gear or not, wherein the change of the acceleration refers to the change of the numerical value of the acceleration; if the backlash exists between the driven transmission gear and the driving transmission gear, controlling a vehicle power device to operate at a first preset torque slopeuntil the backlash is eliminated; and if the backlash between the driven transmission gear and the driving transmission gear is eliminated, controlling the vehicle power device to operate at a secondpreset torque slope until the target torque is reached. The invention further discloses a vehicle output torque control device and a storage medium. By the adoption of the method and device, when thebacklash exists in the vehicle, the vehicle can run according to the first preset torque slope so as to be prevented from shifting and impacting; and after the backlash is eliminated, a motor operates at a second preset torque slope, and the final target torque is rapidly achieved.
本发明公开了一种车辆输出扭矩的控制方法,包括:获取车辆行驶的加速度;若车辆行驶的加速度发生变化,则判断被动传动齿轮和主动传动齿轮之间是否存在齿间隙;加速度发生变化是指加速度的数值大小发生变化;若被动传动齿轮和主动传动齿轮之间存在齿间隙,则控制车辆动力装置以第一预设扭矩斜率运行直至齿间隙消除;若被动传动齿轮和主动传动齿轮之间的齿间隙消除,则控制车辆动力装置以第二预设扭矩斜率运行直至目标扭矩。本发明还公开了一种车辆输出扭矩的控制装置及存储介质。采用本发明,能够使得车辆在存在齿间隙时,便按照第一预设扭矩斜率运行以避免窜动和冲击;进而当间隙消除后,再以第二预设扭矩斜率运行,快速达到最终的目标扭矩。
