The invention relates to a vehicle early warning method and device, a vehicle and a storage medium, and the method comprises the steps: obtaining a first position measurement value corresponding to a target obstacle detected at a current moment when the vehicle is in a target mode, and obtaining a first position estimation value corresponding to a target obstacle detected at a previous moment of the current moment, the target mode is used for representing that surrounding obstacles are detected when the vehicle stops; processing the first position measurement value and the first position estimation value by using a Kalman filtering algorithm to determine a second position estimation value corresponding to the target obstacle at the current moment; performing weighted average processing on the first position estimation value and the second position estimation value to obtain a target position corresponding to the target obstacle at the current moment; and performing early warning on the vehicle according to the target position. The accuracy of early warning of the vehicle according to the obstacles around the vehicle is improved.
本申请涉及一种车辆预警方法、装置、车辆及存储介质,方法包括:在车辆处于目标模式时,获取当前时刻所检测到的目标障碍物对应的第一位置测量值及获取当前时刻的上一时刻所检测到的目标障碍物对应的第一位置估计值,目标模式用于表征车辆在停止时对周围的障碍物进行检测;利用卡尔曼滤波算法对第一位置测量值和第一位置估计值进行处理,以确定当前时刻目标障碍物对应的第二位置估计值;对第一位置估计值和第二位置估计值进行加权平均处理,以得到当前时刻目标障碍物对应的目标位置;根据目标位置,对车辆进行预警。本申请提高了根据车辆周围的障碍物对车辆进行预警的准确性。
