Method and device for preventing continuous collision of multiple sliding vehicles on ramp and vehicle

The invention relates to a ramp multi-vehicle sliding continuous collision prevention method and device and a vehicle. The method comprises the steps that running parameters of a current vehicle and a front vehicle on a ramp, a first distance between the current vehicle and the front vehicle and a second distance between the current vehicle and a rear vehicle are collected through a vehicle-mounted detection sensor; according to the running parameters of the front vehicle on the ramp and the first distance between the current vehicle and the front vehicle, first running safety time and the predicted collision speed of the front vehicle on the ramp and the current vehicle are calculated; judging whether the collision speed is smaller than a preset safety speed or not; if the collision speed is smaller than the preset safety speed, the current vehicle runs backwards at the braking speed, and after the two vehicles collide and make contact with each other, the current vehicle is braked until the current vehicle
