The invention relates to the technical field of new energy vehicles, in particular to a vehicle torque adjusting method and device, a vehicle and computer equipment. The vehicle torque adjusting method comprises the steps that the driving state of a vehicle is obtained, and whether the vehicle meets smooth adjusting conditions or not is judged based on the driving state; in response to the vehicle meeting the smooth adjustment condition, calculating a target acceleration of the vehicle in combination with the state parameter combination of the vehicle and the driving gradient; comparing the target acceleration with the expected acceleration to obtain a difference parameter, and analyzing the difference parameter to obtain a torque smoothing factor; wherein the state parameter combination comprises expected acceleration; and limiting the target torque of the driving motor by using the torque smoothing factor to form a motor request torque, and sending the motor request torque to a motor control module. By the adoption of the method, the torque can be controlled in combination with the driving gradient, and the smoothness and the dynamic property of the vehicle can be guaranteed at the same time through closed-loop control over the acceleration and the torque.

    本申请涉及新能源汽车技术领域,特别是涉及一种车辆扭矩的调节方法、装置、车辆以及计算机设备。车辆扭矩的调节方法包括:获取车辆的行驶状态,基于行驶状态判断车辆是否符合平顺调节条件;响应于车辆符合平顺调节条件,结合车辆的状态参数组合以及行驶坡度计算车辆的目标加速度;比对目标加速度与期望加速度二者,得到差异参数,解析与差异参数获取扭矩平滑因子;其中,状态参数组合包括期望加速度;利用扭矩平滑因子限制驱动电机的目标扭矩,形成电机请求扭矩,向电机控制模块发送电机请求扭矩。采用本方法能够结合行驶坡度对扭矩进行控制,通过加速度与扭矩的闭环控制,有利于同时保证车辆的平顺性以及动力性。
