针对视线受阻导致 AEB 无法及时触发的问题,提出 V2X 触发部分制动、车载传感器触发 AEB 的两阶段制动方案,并在交叉路口用例中评估避撞率与伤害减轻效益。
摘要:
如果两辆车之间即将发生碰撞,自动紧急制动(AEB)会被启动,以避免或减轻事故。然而,AEB 的触发机制依赖车辆的车载传感器,例如雷达和摄像头,这些传感器需要视线才能检测到碰撞对象。如果视线受损,例如因恶劣天气或障碍物而受阻,AEB 就无法及时启动以避免碰撞。为应对这些情况,本文提出一种两阶段制动系统:第一阶段包括由车用无线通信技术(Vehicle-to-everything,V2X)触发的部分制动;第二阶段由标准 AEB 组成,且该 AEB 仅由车载传感器检测触发。本文在受阻的交叉路口用例中分析这种 V2X 增强型两阶段制动系统的性能,并将结果与仅使用 AEB 的系统进行比较。其效益通过确定碰撞避免率进行定量评估;如果碰撞无法避免,则通过估计碰撞严重程度的缓解程度进行评估。
英文摘要:
If a crash between two vehicles is imminent, an Automatic Emergency Brake (AEB) is activated to avoid or mitigate the accident. However, the trigger mechanism of the AEB relies on the vehicle's onboard sensors, such as radar and cameras, that require a line of sight to detect the crash opponent. If the line of sight is impaired, for example by bad weather or an obstruction, the AEB cannot be activated in time to avoid the crash. To deal with these cases, a 2-stage braking system is proposed, where the first stage consists of a partial brake that is triggered by Vehicle-to-everything (V2X) communication. The second stage is composed of the standard AEB that is triggered exclusively by an onboard sensor detection. The performance of this V2X-enhanced 2-stage braking system is analysed in obstructed crossing use cases and the results are compared against the use of an AEB-only system. The benefit is quantitatively assessed by determination of the crash avoidance rate and, if the crash cannot be avoided, by estimation of the crash severity mitigation.
