The invention discloses a threshold adjustment method and system for a vehicle active safety early warning system, and the method comprises the steps: collecting vehicle driving data, driving environment data, driver state data and active safety early warning data in real time; the method comprises the following steps: constructing a vehicle driving safety early warning data set and a driver abnormal state early warning data set of early warning mode categories coupled with different driving road scenes and driving weather environments, respectively establishing early warning lag and early warning advance early warning threshold evaluation indexes for different early warning categories, and adjusting and judging early warning thresholds based on the evaluation indexes. And adjusting the early warning threshold according to the evaluation result. According to the invention, the early warning threshold value of the active safety system can be continuously quantitatively evaluated and adjusted based on the early warning system and the early warning data collected in real time in the vehicle driving process, and the reliability and robustness of the active safety early warning system are further improved.

    本发明公开了一种车辆主动安全预警系统阈值调整方法及系统,通过实时采集到的车辆行驶数据、驾驶环境数据、驾驶人状态数据和主动安全预警数据,构建不同驾驶道路场景与驾驶天气环境耦合的预警模式类别的车辆行驶安全预警数据集和驾驶人异常状态预警数据集,分别针对不同预警类别下建立预警滞后和预警提前预警阈值评估指标,基于评估指标对预警阈值进行调整判别,根据评价结果对预警阈值进行调整。本发明能够基于预警系统与车辆行驶过程中实时采集的预警数据不断量化评估并调整主动安全系统的预警阈值,进一步提高主动安全预警系统的可靠度和稳健性。
