智能运输系统. 驻车辅助系统(APS). 性能要求和试验规程

[中文适用范围]： 本文件涵盖了轻型车辆的辅助停车系统（APS），例如配备此类 APS 的客车、皮卡车、轻型货车和运动型多功能车（摩托车除外）。 该文件规定了驾驶员对系统的最低功能要求，例如检测合适的停车位、计算轨迹和车辆的横向控制。 有关车辆行驶路径中相关障碍物存在的信息也可以包含在此类系统的功能中。 本文件还规定了故障指示和性能测试程序的最低要求。 它包括一般信息策略的规则，但不限制信息或显示系统的种类。 APS 旨在为驾驶员提供自动停车辅助功能。 APS 在车辆附近的环境中搜索其他停放车辆之间的合适停车区域或道路上的标记（例如画线），评估所需信息以计算停车轨迹，并将转向命令发送到转向系统的电子接口以进行横向控制停车操作期间车辆的情况。 APS 的基本功能是在停车操作期间协助驾驶员对车辆进行横向控制。 作为可选的扩展，APS 还可以对车辆运动提供有限的纵向控制，例如在驶入停车位时提供制动辅助。 本文件包含对APS横向控制能力的要求。 它不涉及纵向控制。 停车操纵过程中，驾驶员可以随时接管车辆运动的控制权，并对停车操纵负全部责任。 APS 使用物体检测设备进行检测和测距，以便在环境中搜索合适的停车区域。 此类设备可以是具有距离信息的传感器或基于视觉的系统。 此外，传感器或计数器以及车辆网络（例如CAN）上可用的相关数据可用于计算车辆相对于停车区域的位置。 APS 是在停车操作中通知驾驶员有关障碍物的系统的扩展（例如，本文件不包括用于重型商用车辆或拖车的辅助停车系统、倒车辅助装置和障碍物检测装置。 [外文原描述]： ISO 16787:2017 covers the assisted parking system (APS) for light-duty vehicles, e.g. passenger cars, pick-up trucks, light vans and sport utility vehicles (motorcycles excluded) equipped with such APS. This document establishes minimum functionality requirements that the driver can expect of the system, such as the detection of suitable parking spaces, calculation of trajectories and lateral control of the vehicle. Information on the presence of relevant obstacles in the driving path of the vehicle can also be included in the functionality of such systems. This document also sets minimum requirements for failure indication as well as performance test procedures. It includes rules for the general information strategy, but does not restrict the kind of information or display system. APS is intended to provide automated parking assistance functionality to the driver. The APS searches the environment adjacent to the vehicle for suitable parking areas between other parked vehicles or markings on the road such as painted lines, evaluates the required information to calculate parking trajectories and sends steering commands to an electronic interface of the steering system for lateral control of the vehicle during the parking manoeuvre. The basic APS function is to assist the driver with lateral control of the vehicle during parking manoeuvres. As an optional extension, APS can also offer limited longitudinal control of the vehicle movement, e.g. braking assistance while manoeuvring into the parking slot. ISO 16787:2017 contains requirements for the lateral control capability of APS. It does not address longitudinal control. During the parking manoeuvre, the driver can take over the control of the vehicle movement at any time and is also fully responsible for the parking manoeuvre. APS uses object-detection devices for detection and ranging in order to search the environment for suitable parking areas. Such devices can be sensors with distance information or vision-based systems. In addition, sensors or counters, as well as relevant data available on the vehicle network (e.g. CAN), may be used to calculate the position of the vehicle relative to the parking area. APS is an extension of systems which inform the driver about obstacles in parking manoeuvres (e.g. ISO 17386 and ISO 22840). ISO 16787:2017 does not include assisted parking systems, reversing aids and obstacle-detection devices for use on heavy commercial vehicles or on vehicles with trailers.
