The invention discloses a collision early warning method and device, and belongs to the field of intelligent control. The method comprises the following steps: acquiring state information, inputting the state information into a collision early warning model, and outputting action information corresponding to the state information; when the action information indicates alarming, performing alarming; when a target instruction is received within a target time period after alarming, obtaining a time difference between a receiving time point and an alarming time point of the target instruction andthe speed information of a vehicle; and updating the collision early warning model according to the time difference and the speed information of the vehicle. According to the invention, the driving habit of a driver is considered, the model is updated according to the feedback of the driver to the alarm, so that an output result of the model, namely the alarm opportunity, more accords with the expectation of the driver, and the accuracy of collision early warning is improved.

    本发明公开了一种碰撞预警方法及装置,属于智能控制领域。方法包括:获取状态信息,将状态信息输入碰撞预警模型,输出状态信息对应的动作信息;当动作信息指示报警时,则进行报警;当在报警后的目标时间段内接收到目标指令时,获取目标指令的接收时间点和报警时间点之间的时间差以及车辆的速度信息;根据时间差以及车辆的速度信息,更新碰撞预警模型。本发明考虑了驾驶员的驾驶习惯,根据驾驶员对本次报警的反馈来更新模型,使得模型的输出结果,也即是报警时机更符合驾驶员的期望,提高了碰撞预警的准确性。
