The invention discloses a control method, device, equipment and system for vehicle reversing uphill, and the method comprises the steps: outputting a driving torque to a power assembly controller under the condition that a reversing uphill auxiliary function is activated and a brake pedal is detected to be released, controlling the vehicle to keep static or run backwards at a speed lower than a preset threshold value; under the condition that the brake pedal is completely released, a torque increment corresponding to the opening degree of an accelerator pedal is obtained, the torque increment is corrected, and a target increment is obtained; and target torque is obtained according to the target increment and the driving torque, and the target torque is output to the power assembly controller so as to control the backward running speed of the vehicle. According to the technical scheme provided by the invention, low-speed stable backing-up of the vehicle can be maintained according to the vehicle speed expected by a driver, and the driving and riding comfort is improved.

    本申请公开了一种车辆倒车上坡的控制方法、装置、设备及系统,其中,所述方法包括:在倒车上坡辅助功能激活并且检测到制动踏板被释放的情况下,向动力总成控制器输出驱动扭矩,以控制车辆保持静止或者以低于预设阈值的车速向后行驶;在所述制动踏板被完全释放的情况下,获取油门踏板的开度对应的扭矩增量,并对所述扭矩增量进行修正,得到目标增量;根据所述目标增量和所述驱动扭矩,得到目标扭矩,并向所述动力总成控制器输出所述目标扭矩,以控制所述车辆向后行驶的车速。通过本申请提供的技术方案能够实现车辆根据驾驶员预期的车速,维持低速平稳倒车,提升了驾乘舒适性。
