The invention discloses a vehicle cruise stabilization method, device and equipment and a computer readable storage medium, and the method comprises the steps: judging whether a current vehicle longitudinal acceleration value is a beneficial value or a harmful value based on a vehicle longitudinal acceleration value measured by an inertia sensor in unit time and the change condition of a compression rate value of a vehicle suspension; if yes, the current vehicle longitudinal acceleration value is used for calculating the vehicle longitudinal control torque, and the calculated vehicle longitudinal control torque is used for controlling the vehicle to run; if yes, the vehicle longitudinal control torque of the last cycle is used for controlling the vehicle to run. If yes, the calculated vehicle longitudinal control torque is used for controlling the vehicle to run, and it is ensured that the vehicle speed is kept stable when the vehicle goes up and down the ramp. If the value is the harmful value, the vehicle longitudinal control torque of the last cycle is used for controlling vehicle running, the influence of a bumpy road on vehicle longitudinal control torque control is ignored, and vehicle speed fluctuation caused by vehicle longitudinal control torque fluctuation is avoided.

    一种车辆巡航稳定方法、装置、设备及计算机可读存储介质,所述车辆巡航稳定方法包括:基于单位时间内惯量传感器测量的车辆纵向加速度值和车辆悬架的压缩速率值变化情况,判断当前的车辆纵向加速度值是有益值还是有害值;若是有益值,使用当前的车辆纵向加速度值进行车辆纵向控制力矩计算,并使用计算后的车辆纵向控制力矩控制车辆行驶;若是有害值,使用上一个循环的车辆纵向控制力矩控制车辆行驶。若是有益值,使用计算后的车辆纵向控制力矩控制车辆行驶,确保车辆上下坡道时车速维持稳定。若是有害值,使用上一个循环的车辆纵向控制力矩控制车辆行驶,忽略颠簸路面对车辆纵向控制力矩控制的影响,避免车辆纵向控制力矩波动导致车速波动。
