本SAE推荐实施规程的目的是为自动车速控制的设计提供一系列工程指南，并定义设备必须提供的最低控制性能，以便将其归类为自动车速控制。自动车速控制装置是一种能够在不断变化的道路负载条件下保持选定车速的装置。本SAE推荐规程仅适用于自动车速控制的设计。其目的不是鼓励或阻止在任何类别的车辆上安装自动车速控制装置，也不是为了影响发动机调速器的要求。

The purpose of this SAE Recommended Practice is to provide a series of engineering guidelines for the design of an automatic vehicle speed control, and to define the minimum control performance which a device must provide in order to be classified an automatic vehicle speed control. An automatic vehicle speed control is a device capable of maintaining selected vehicle speeds in the presence of changing road load conditions. This SAE Recommended Practice is intended to apply only to the design of an automatic vehicle speed control. It is not intended to encourage or discourage the installation of automatic vehicle speed controls on any class of vehicles, nor is it intended to influence the requirements of engine speed governors.
