The embodiment of the invention provides a vehicle overtaking prompting method and device, and the method comprises the steps: obtaining image data behind a user vehicle shot by a camera device, and detecting the acceleration and distance of a rear vehicle through the image data when a preset distance of the user vehicle in the image data contains a vehicle; acquiring the acceleration of the user vehicle, calculating the acceleration difference between the two vehicles when the acceleration of the rear vehicle is greater than the acceleration of the user vehicle, and calculating the overtaking time of the rear vehicle according to the acceleration difference and the distance between the rear vehicle; when the overtaking time exceeds the preset duration, the deceleration corresponding to the user vehicle is calculated according to the overtaking time, and the deceleration is used for adjusting the acceleration of the user vehicle so that the overtaking time does not exceed the preset duration; and generating a deceleration scheme, and sending deceleration information to a driver of the user vehicle through the human-vehicle interaction device. By adopting the method, when the overtaking time of the rear vehicle is too long, the front vehicle is reminded to decelerate, so that the overtaking action of the rear vehicle is quickly completed, and dangerous accidents during overtaking are avoided.

    本发明实施例提供一种车辆被超车提示方法及装置,所述方法包括:获取摄像装置拍摄的用户车辆后方的图像数据,并当图像数据中用户车辆的预设距离内包含车辆时,通过图像数据检测后车加速度及后车距离;获取用户车辆加速度,当后车加速度大于用户车辆加速度时,计算两车的加速度差,根据加速度差及后车距离计算后车的超车用时;当超车用时超过预设时长时,根据超车用时计算用户车辆对应的减速度,减速度用于调整用户车辆的加速度使超车用时不超过预设时长;生成减速方案,并通过人车交互装置向用户车辆的驾驶员发送减速信息。采用本方法能够在后车超车时长过长时,提醒前车减速使得后车超车动作快速完成,进而避免超车时危险事故的发生。
