The invention discloses a self-vehicle driving risk quantification method and system considering road constraints, and the method comprises the following steps: obtaining driving information which comprises vehicle data of a self-vehicle and road data of a driving road where the self-vehicle is located; based on the driving information, obtaining a lane departure risk amount and an overspeed risk amount of the vehicle; and based on the vehicle lane departure risk amount and the vehicle overspeed risk amount, obtaining a first driving risk value representing the vehicle driving risk of the road constraint angle. According to the method, aiming at the bad driving risk of the vehicle under the constraint of the road traffic rule, the vehicle lane departure risk amount considering the transverse constraint and the vehicle overspeed risk amount considering the longitudinal constraint are obtained in the transverse direction and the longitudinal direction respectively, so that the vehicle can know the risk degree of the driving state of the vehicle in time; the driving safety is ensured by timely adjusting the state.
本发明公开了一种考虑道路约束的自车行车风险量化方法及系统,包括以下步骤:获取行车信息,所述行车信息包括自车的车辆数据以及自车所在行驶道路的道路数据;基于所述行车信息,得到自车车道偏离风险量和自车超速风险量;基于所述自车车道偏离风险量和自车超速风险量,得到表征道路约束角度的自车行车风险的第一行车风险值。本发明的方法,针对自车在道路交通规则约束下的不良驾驶风险,以横、纵两个方向分别得到考虑横向约束的自车车道偏离风险量与考虑纵向约束的自车超速风险量,有助于车辆及时获知自车驾驶状态的风险程度,及时调整状态保障行车安全。
