Currently, vehicles are often equipped with active safety systems to reduce the risk of accidents, most of which occur in urban environments. The most prominent include Antilock Braking Systems (ABS), Traction Control and Stability Control. All these systems use different kinds of sensors to constantly monitor the conditions of the vehicle, and act in an emergency. In this paper the use of ultrasonic sensors in active safety systems for urban traffic is proposed, and the advantages and disadvantages when compared to other sensors are discussed. Adaptive Cruise Control (ACC) for urban traffic based on ultrasounds is presented as an application example. The proposed system has been implemented in a fully-automated prototype vehicle and has been tested under real traffic conditions. The results confirm the good performance of ultrasonic sensors in these systems.
目前，车辆通常配备有主动安全系统以降低事故风险，其中大多数事故发生在城市环境中。最突出的包括防抱死制动系统 (ABS)、牵引力控制和稳定性控制。所有这些系统都使用不同类型的传感器来不断监测车辆的状况，并在紧急情况下采取行动。本文提出了在城市交通中的主动安全系统中使用超声波传感器，并讨论了与其他传感器相比的优缺点。提出了基于超声波的城市交通自适应巡航控制 (ACC) 作为应用实例。所提出的系统已在全自动原型车辆中实现，并在实际交通条件下进行了测试。结果证实了超声波传感器在这些系统中的良好性能。
