摘要
人车混合是我国道路交通的普遍特点,由于行人等弱势道路使用者与汽车相互间没有察觉到对方的交通意图而导致事故的情况时有发生.车外提示音相关标准的制定和实施能给弱势道路使用者以有效的安全提醒,减少伤亡事故的发生。本文重点分析并介绍了我国已经出台的电动汽车低速行驶提示音、车辆右转弯提示音要求和试验方法和正在制定中的车辆倒车提示音要求和试验方法三项国家标准的背景意义、技术要求及指标确定原则,为国内汽车相关企业和科研院所开展车外提示音标准的研究提供参考。
People-vehicle mixed situation is the general character of China’s road traffic. Accidents occur frequently because of the unawareness of the traffic intention between pedestrians and vehicles. The development and implementation of external vehicle alert standards give vulnerable road users effective safety warnings, thus decreasing the occurrence of the traffic accident. Current standard"Acoustic vehicle alerting system of electric vehicles running at low speed"and "Requirements and test methods of alert for vehicle turning right"and "Alert for Vehicle Reversing and Testing Method"under development are introduced and analyzed in this paper. The background,technical requirements and principle of index determination of three standards are given and reference is provided to related automobile enterprises and research institutes to conduct research on external vehicle alert standards.
