The invention provides a vehicle speed control method and device, equipment and a computer readable medium. The method comprises the following steps: S1, obtaining a maximum vehicle speed value, a current vehicle speed, a current gear signal and a current accelerator pedal opening signal when a vehicle is in a state of limiting the maximum vehicle speed; S2, obtaining a target torque limit value meeting the highest vehicle speed through calculation according to the highest vehicle speed value, the current vehicle speed and the current gear signal, and obtaining a torque value required by a driver through calculation according to the current vehicle speed and the current accelerator pedal opening degree signal; and S3, obtaining a final torque output value according to the target torque limit value and the driver demand torque value, and controlling to output the final torque output value. Compared with the prior art, the vehicle speed can be stabilized more quickly, obvious fluctuationof the vehicle speed is avoided when the vehicle has an over-temperature risk, and more excellent driving feeling can be brought to customers on the premise of ensuring safety.

    本发明提供一种车辆速度的控制方法、装置、设备及计算机可读介质,其中,该方法包括如下步骤:S1、当车辆处于限制最高车速状态时,获取最高车速值、车辆当前车速、当前档位信号以及当前油门踏板开度信号;S2、根据最高车速值、车辆当前车速和当前档位信号计算获得满足最高车速的目标扭矩限制值,以及根据车辆当前车速和当前油门踏板开度信号计算获得驾驶员需求扭矩值;S3、根据目标扭矩限制值和所述驾驶员需求扭矩值获得最终扭矩输出值,并控制输出最终扭矩输出值。本发明相较于其它现有技术能更快地实现车速的稳定,在车辆发生过温风险时避免车速明显波动,在保证安全的前提下能带给客户更优越的驾驶感受。
