The invention relates to a vehicle collision early warning sensitivity adjusting method and device. The method comprises the steps that the transverse acceleration of a current vehicle and the real-time vehicle following distance and the relative speed between the current vehicle and a forward vehicle are obtained; according to the real-time vehicle following distance and the relative speed, the remaining duration of the collision accident between the current vehicle and the forward vehicle is determined; under the condition that the residual duration and the transverse acceleration both meet the preset collision early warning condition, collision early warning prompt information is sent; obtaining obstacle avoidance operation data returned based on the collision early warning prompt information, wherein the obstacle avoidance operation data comprises an obstacle avoidance operation type and an obstacle avoidance interval duration between the moment of sending the collision early warning prompt information and the moment of obtaining the obstacle avoidance operation data; and adjusting a preset collision early warning condition according to the obstacle avoidance operation type and the obstacle avoidance interval duration. By adopting the method, the driving style of the driver can be identified in real time in the vehicle driving process, and the early warning sensitivity is adjusted according to the driving style.

    本申请涉及一种车辆碰撞预警灵敏度调节方法及装置。方法包括:获取当前车辆的横向加速度、以及当前车辆与前向车辆之间的实时跟车距离和相对速度;根据实时跟车距离和相对速度,确定当前车辆和前向车辆之间发生碰撞事故的剩余时长;在剩余时长和横向加速度均满足预设碰撞预警条件的情况下,发送碰撞预警提示信息;获取基于碰撞预警提示信息返回的避障操作数据,避障操作数据包括避障操作类型、以及发送碰撞预警提示信息的时刻与获取避障操作数据的时刻之间的避障间隔时长;根据避障操作类型和避障间隔时长,调节预设碰撞预警条件。采用本方法能够在车辆行驶过程中实时鉴别驾驶员的驾驶风格,来根据驾驶风格调节预警灵敏度。
