The invention relates to the technical field of vehicle collision early warning, and provides a method and device for adjusting the collision early warning sensitivity of a vehicle. The method comprises the steps that face recognition data of a driver and control data of the driver for a steering wheel are obtained, the face recognition data are used for indicating the attention of eyes of the driver to a road, and the control data are used for indicating the control degree of the driver to a vehicle; determining a target attention score of the driver driving the vehicle according to the face recognition data and the control data; determining a target sensitivity corresponding to the target attention score according to a preset corresponding relationship between the attention score and the sensitivity of collision early warning; and adjusting the sensitivity of the collision early warning of the vehicle to the target sensitivity. The technical problem that in the prior art, a vehicle collision early warning system is low in sensitivity and accuracy is solved.

    本申请涉及车辆碰撞预警技术领域,提供了一种调节车辆的碰撞预警灵敏度的方法及装置。该方法包括:获取驾驶员的面部识别数据和驾驶员针对方向盘的控制数据,其中面部识别数据用于指示驾驶员眼部对道路的注意度,控制数据用于指示驾驶员对车辆的控制度;根据面部识别数据和控制数据,确定驾驶员驾驶车辆的目标注意力评分;根据预先设置的注意力评分与碰撞预警的灵敏度之间的对应关系,确定目标注意力评分对应的目标灵敏度;将车辆的碰撞预警的灵敏度调整为目标灵敏度。本申请解决了现有技术中车辆碰撞预警系统的灵敏度准确性低的技术问题。
