The invention discloses a collision detection method and device, electronic equipment and a readable storage medium. The method comprises the steps that the current vehicle speed and the current acceleration of a vehicle are obtained, a collision acceleration threshold value corresponding to the current vehicle speed is determined according to a preset historical collision fitting curve, and two coordinate axes of the historical collision fitting curve are the vehicle speed threshold value and the collision acceleration threshold value respectively; the preset historical collision fitting curve is obtained after historical vehicle speed and historical collision acceleration in the historical collision data are analyzed, the absolute value of the current acceleration is compared with a collision acceleration threshold value, and if the absolute value of the current acceleration is larger than the collision acceleration threshold value, behavior data of the driver are obtained; and judging whether the vehicle collides according to the behavior data. Whether the vehicle is collided or not can be judged according to the current speed and the current acceleration of the vehicle, the judgment result is further verified according to the data of the behaviors of the driver, and vehicle collision misjudgment can be effectively reduced.
本申请公开一种碰撞检测方法、装置、电子设备和可读存储介质。方法包括:获取车辆的当前车速和当前加速度,根据预设的历史碰撞拟合曲线,确定与当前车速对应的碰撞加速度阈值,其中,历史碰撞拟合曲线的两个坐标轴分别为:车速和碰撞加速度阈值,预设的历史碰撞拟合曲线是对历史碰撞数据中的历史车速和历史碰撞加速度进行分析后得到的,将当前加速度的绝对值与碰撞加速度阈值进行比较,若当前加速度的绝对值大于碰撞加速度阈值,则获取驾驶员的行为数据,通过行为数据判断车辆是否发生碰撞。本申请可以通过车辆的当前车速和当前加速度判断车辆是否发生碰撞,并进一步通过驾驶员已发生行为数据对判断结果进行验证,可以有效减小发生车辆碰撞误判。
