Vehicle speed control method and device, medium and vehicle

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
