The invention provides a vehicle lane changing prompting method and system, terminal equipment and a storage medium, and belongs to the technical field of vehicle safety, and the method comprises the following steps: obtaining real-time vehicle speeds of a target vehicle and a first reference vehicle, the first reference vehicle being a vehicle driving in a to-be-changed lane of the target vehicle and closest to the tail of the target vehicle; a first vehicle speed difference is calculated, when it is judged that the absolute value of the first vehicle speed difference is larger than or equal to a first speed threshold value, a first adjusting amount is obtained according to the first vehicle speed difference, the first critical line is moved, a first updated critical line is obtained, and then a first updated alarm area is obtained; when it is judged that the head of the first reference vehicle crosses the first updating critical line, an early warning signal is sent out; when it is judged that the first reference vehicle enters the first updated alarm area, an alarm signal is sent out. According to the scheme, corresponding reminding is given to the target vehicle based on the first updated alarm area, effective indication is provided for a user of the vehicle waiting for lane changing, and vehicle and personal safety is guaranteed.
本申请提供一种车辆变道的提示方法、系统、终端设备及存储介质,属于车辆安全技术领域,该方法包括以下步骤:获取目标车辆和第一参照车辆的实时车速,第一参照车辆为行驶在目标车辆的待变车道内、距目标车辆尾部最近的车辆;计算第一车速差,判断第一车速差的绝对值大于或等于第一速度阈值时,根据所述第一车速差得到第一调节量,移动第一临界线,得到第一更新临界线,进而得到第一更新后报警区域;判断第一参照车辆的头部越过第一更新临界线时,发出预警信号;判断第一参照车辆驶入第一更新后报警区域时,发出报警信号。该方案基于第一更新后报警区域对目标车辆给予对应的提醒,为待变道车辆的用户提供有效指示,保障车辆和人身安全。
