ISO 16787:2017涵盖了轻型车辆的辅助停车系统（APS），例如乘用车、皮卡车、轻型货车和配备此类辅助停车系统的运动型多用途车（摩托车除外）。本文件规定了驾驶员对系统的最低功能要求，如检测合适的停车位、计算轨迹和车辆横向控制。此类系统的功能还包括有关车辆行驶路径中是否存在相关障碍物的信息。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泊车辅助功能。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（如喷漆线），评估计算停车轨迹所需的信息，并向转向系统的电子接口发送转向命令，以便在停车操纵期间对车辆进行横向控制。 APS的基本功能是在驻车操控期间协助驾驶员对车辆进行横向控制。 作为可选扩展，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。 ISO 16787:2017包含APS横向控制能力的要求。它不涉及纵向控制。 在驻车操纵过程中，驾驶员可以随时控制车辆移动，并对驻车操纵负全部责任。 APS使用目标检测设备进行检测和测距，以便在环境中搜索合适的停车场。这种设备可以是具有距离信息或视觉的传感器- 基于网络的系统。此外，传感器或计数器以及车辆网络（如CAN）上可用的相关数据可用于计算车辆相对于停车区的位置。 APS是系统的扩展，用于告知驾驶员停车操作中的障碍物（例如ISO 17386和ISO 22840）。 ISO 16787:2017不包括重型商用车或带拖车的车辆上使用的辅助停车系统、倒车辅助装置和障碍物检测装置。

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.
