The invention discloses a vehicle and a control method thereof, a storage medium, an electronic device, and the method comprises the steps: obtaining first BSM information of the vehicle and second BSM information of a front vehicle, the first BSM information comprising a first vehicle speed, a first position and a first acceleration, and the second BSM information comprising a second vehicle speed, a second position and a second acceleration; when the first vehicle speed is larger than a low-speed threshold value, the vehicle distance between the vehicle and the front vehicle is obtained according to the first position and the second position; when the vehicle distance is smaller than the vehicle distance threshold value, the collision time of the vehicle and the front vehicle is calculated according to the first vehicle speed, the second vehicle speed, the first acceleration, the second acceleration and the vehicle distance; according to the forward collision time threshold empirical value, the first vehicle speed and the relative acceleration, a forward collision time threshold is obtained; and when the collision time is smaller than the forward collision time threshold value, the vehicle is controlled to give forward collision early warning. Therefore, collision judgment is carried out by adopting the collision time threshold value obtained in the self-adaptive mode, and the collision risk can be better reduced.
本发明公开了一种车辆及其控制方法、存储介质和电子和设备,方法包括:获取本车的第一BSM信息和前车的第二BSM信息,第一BSM信息包括第一车速、第一位置和第一加速度,第二BSM信息包括第二车速、第二位置和第二加速度;当第一车速大于低速阈值时,根据第一位置和第二位置得到本车与前车的车间距;当车间距小于车间距阈值时,根据第一车速、第二车速、第一加速度、第二加速度和车间距,计算本车与前车的碰撞时间;根据前向碰撞时间阈值经验值、第一车速和相对加速度,得到前向碰撞时间阈值;当碰撞时间小于前向碰撞时间阈值时,控制本车发出前向碰撞预警。由此,采用自适应方式得到的碰撞时间阈值进行碰撞判断,可更好地减少碰撞风险。
