The invention discloses a driving risk quantification method, system and equipment based on driver perception. The driving risk quantification method comprises the following steps: acquiring a risk perception factor of a vehicle; based on the risk perception factor, a driving risk value representing the driving risk is obtained through a driving risk quantification expression; wherein the risk perception factor of the vehicle is represented by the instantaneous acceleration of the vehicle. Compared with the prior art, the driving risk quantification method provided by the invention starts from the perspective of driver perception and takes the acceleration taken by the driver as a risk factor perceived by the driver; according to the driving risk quantification method based on the risk factor, the influence of other traffic vehicles on the driving safety of the vehicle in the environment can be expressed from the perception perspective of a driver, so that early potential safety hazards of the vehicle can be found, and a basis can be provided for a driving early warning mechanism; and the driving risk possibly faced by the automatic driving vehicle during execution of a certain strategy can be quantified from the perspective of driver perception, and a reference basis is provided for decision making of the automatic driving vehicle.
本发明公开了一种基于驾驶人感知的行车风险量化方法、系统及设备,其中行车风险量化方法包括如下步骤:获取自车的风险感知因子;基于风险感知因子,通过行车风险量化表达式,得到表征行车风险的行车风险值;其中,自车的风险感知因子通过自车的瞬时加速度表征。与现有技术相比,本发明的行车风险量化方法从驾驶人感知角度出发,以驾驶人所采取的加速度作为驾驶人感知的风险因子,基于该风险因子的行车风险量化方法可以从驾驶人的感知角度来表达环境中其它交通车对自车行车安全的影响,利于车辆发现早期安全隐患,可以为行车预警机制提供依据,也可以从驾驶人感知角度量化自动驾驶车辆在执行某个策略时可能面临的行车风险,为其决策提供参考依据。
