The embodiment of the invention provides a vehicle speed control method, a controller, a vehicle and a storage medium, and belongs to the technical field of vehicle motion control. The method comprises the steps of firstly obtaining the current vehicle speed of a target vehicle, then obtaining speed error data by calculating an error between the current vehicle speed and a preset target vehicle speed, then determining a vehicle speed variation according to the current vehicle speed and a preset time period, and then performing differential increment calculation by using the current vehicle speed variation and a preset differential gain coefficient to obtain a differential increment value; and an acceleration control signal is obtained. Then, performing signal integration calculation according to the speed error data, a preset integral gain coefficient, a preset proportional gain coefficient and the acceleration control signal to obtain a target acceleration increment signal; and finally, the vehicle is controlled according to the target acceleration increment signal, so that the vehicle runs at the target vehicle speed. The embodiment of the invention can control the vehicle to quickly reach the expected speed and keep running at the expected speed.
本申请实施例提供了一种车速控制方法、控制器、车辆及存储介质,属于汽车运动控制技术领域。该方法包括:首先获取目标车辆的当前车速,然后通过计算当前车速与预设目标车速之间的误差,得到速度误差数据,接着,根据当前车速和预设时段确定车速变化量,然后利用当前车速变化量和预设微分增益系数进行微分增量计算,得到加速度控制信号。然后,根据速度误差数据、预设积分增益系数、预设比例增益系数和加速度控制信号进行信号整合计算,得到目标加速度增量信号。最后,根据目标加速度增量信号对车辆进行控制,使其以目标车速行驶。本申请实施例可以控制车辆快速达到预期速度并保持以预期速度行驶。
