The invention provides a vehicle anti-collision device and method, a vehicle, electronic equipment and a medium, and the vehicle anti-collision method comprises the steps: obtaining a relative speed and a vehicle distance; establishing a relation function of the relative speed with respect to time, and determining that the derivative of the relation function at the current moment is the relative acceleration of the vehicle and the rear vehicle; determining a collision risk level of the vehicle according to the relative speed and the relative acceleration; when the collision risk grade is larger than or equal to a first threshold value and the vehicle distance is smaller than or equal to a second threshold value, the airbag is controlled to be opened, and the driving device is controlled to drive the supporting structure to be switched to the unfolded state. The collision risk of the vehicle and the rear vehicle can be automatically detected, the air bag is automatically opened and the supporting structure is unfolded when the collision risk is large, the buffering effect can be achieved, impact on a driver of the rear vehicle is reduced, and the safety of the driver is guaranteed.
本发明提供一种车辆防碰撞装置、方法、车辆、电子设备及介质,其中,车辆防碰撞方法包括:获取相对速度和车距;建立相对速度关于时间的关系函数,确定关系函数在当前时刻的导数为本车与后方车辆的相对加速度;根据相对速度与相对加速度确定车辆的碰撞风险等级;根据碰撞风险等级大于或等于第一阈值且车距小于或等于第二阈值,控制气囊打开,并控制驱动装置带动支撑结构切换至展开状态。本发明能够自动检测本车与后方车辆的碰撞风险,并在碰撞风险较大时自动开启气囊并展开支撑结构,可以起到缓冲作用,减少对后方车辆驾驶员的冲击,保证驾驶员安全。
