The invention relates to the technical field of automatic driving, in particular to a vehicle speed control method and device, a medium and a vehicle. The method comprises the following steps: determining a speed regulation coefficient according to a vehicle speed and a target vehicle speed; the target vehicle is a cut-in vehicle between the own vehicle and the front vehicle; determining an initial acceleration according to the actual distance between the vehicle and the target vehicle, the speed of the vehicle, the obtained maximum acceleration and a preset minimum acceleration; determining a target acceleration of the vehicle according to the initial acceleration and the speed regulation coefficient; and advancing according to the target acceleration. Therefore, the problems that the safety of the vehicle is reduced, the comfort is poor and the like due to the fact that an existing ACC brakes violently when facing other vehicles are cut in can be effectively solved.
本申请涉及自动驾驶技术领域,尤其涉及一种车辆速度控制方法、装置、介质及车辆。该方法包括:根据自身车辆速度和目标车辆速度确定速度调节系数;所述目标车辆为所述自身车辆与前车之间的切入车辆;根据所述自身车辆与所述目标车辆的实际车距、所述自身车辆速度、获取的最大加速度以及预设的最小加速度,确定初始加速度;根据所述初始加速度和所述速度调节系数,确定所述自身车辆的目标加速度;根据所述目标加速度行进。由此,本申请可以有效解决现有ACC在面临他车切入时进行剧烈刹车,导致车辆安全性降低、舒适感差的问题等。
