基于道路驾驶技能考试的辅助制动策略探索与实践

Research on and Practice of Emergency Braking System Strategy in Road Driving Test

针对道路驾驶技能考试避险需求,本文利用辅助驾驶新技术,研究路考典型场景下的制动策略,并开展测试评价。基于考试员紧急踩副制动的常见情形,构建了3种典型路考场景;通过建立场景的运动学模型,解析制动安全边界范围及影响因素;试制辅助制动系统样机,并对制动性能开展功能测评,验证系统的有效性和安全性,从技术层面探索了路考辅助制动的新方法。

To address the risk avoidance demands during the road driving test,based on the common situation that examiners put on the brake in an emergency,three typical road test scenarios are constructed by using the new technology of assisted driving.By studying the kinematic model of the scene,the range of braking safety boundary and its infl uencing factors are analyzed.The prototype of the emergency braking system is produced as a trial,and the braking performance is evaluated to verify the effectiveness and safety of the system.A new method of road test assisted braking is explored at the technical level.
