The invention discloses an automatic driving vehicle driving safety degree quantification system which comprises a driving area environment risk quantification module, a surrounding traffic participant conflict interference quantification module, a vehicle behavior risk quantification module, a vehicle driving safety degree quantification module and a display module. Wherein outputs of the driving area environment risk quantification module, the surrounding traffic participant conflict interference quantification module and the self-vehicle behavior risk quantification module are finally synthesized to the vehicle driving safety degree quantification module, a vehicle driving real-time safety degree value is obtained through calculation, and the vehicle driving real-time safety degree value is displayed on the display module in different colors in a distinguished mode. And reminding a driver of the safety state of the automatic driving system. According to the system, environmental complexity, surrounding traffic participant interference and self behavior state factors which influence the safety degree of a human driver during driving are quantified, safety warnings of different degrees can be provided for an automatic driving vehicle system and the human driver in the automatic driving vehicle system, and the vehicle is restrained to be in a relatively stable driving state.
本发明公开了一种自动驾驶车辆驾驶安全度量化系统,包括驾驶区域环境风险量化模块、周围交通参与者冲突干扰量化模块、自车行为风险量化模块、车辆驾驶安全度量化模块、显示模块,其中驾驶区域环境风险量化模块、周围交通参与者冲突干扰量化模块和自车行为风险量化模块的输出最终合成至车辆驾驶安全度量化模块,计算得到车辆驾驶实时安全度值,采用不同颜色区别显示于显示模块,提示驾驶员自动驾驶系统的安全度状态。该系统将影响人类驾驶员在驾车时安全度的环境复杂度、周围交通参与者干扰、自身行为状态因素进行量化,可以对自动驾驶车辆系统及其中的人类驾驶员提供不同程度的安全警示,约束车辆使其处于一种相对稳定的行驶状态。
