The invention relates to a vehicle longitudinal control method and device, a vehicle and a storage medium. The method comprises the following steps: receiving a longitudinal control request for a vehicle, wherein the longitudinal control request comprises an input control quantity; determining a first output torque according to the input control quantity; acquiring the resistance torque of the vehicle; compensating the first output torque according to the resistance torque to obtain a second output torque; and controlling motor operation of the vehicle according to the second output torque so as to perform longitudinal control on the vehicle. The method comprises the steps of obtaining a first output torque through a longitudinal control request, then obtaining a resistance torque of a vehicle, compensating the first output torque according to the resistance torque of the vehicle to obtain a second output torque, controlling a motor of the vehicle to operate according to the second output torque, and carrying out longitudinal control on the vehicle. The influence of the resistance borne by the vehicle in the running process on the longitudinal movement of the vehicle can be compensated, so that the second output torque can be accurately and rapidly obtained, and the longitudinal control effect of the vehicle is improved.
本公开涉及一种车辆纵向控制方法、装置、车辆及存储介质。该方法包括:接收到针对车辆的纵向控制请求,纵向控制请求包括输入控制量;根据输入控制量,确定第一输出扭矩;获取车辆的阻力扭矩;根据阻力扭矩对第一输出扭矩进行补偿,得到第二输出扭矩;根据第二输出扭矩控制车辆的电机运行,以对车辆进行纵向控制。通过纵向控制请求获得第一输出扭矩,然后,获取车辆的阻力扭矩,并根据车辆的阻力扭矩对第一输出扭矩进行补偿,得到第二输出扭矩,根据第二输出扭矩控制车辆的电机运行,对车辆进行纵向控制,这样,能够补偿车辆在行驶过程中受到的阻力对车辆纵向运动的影响,从而能够准确、快速地获取到第二输出扭矩,提升车辆纵向控制的效果。
