The work of preparing International Standards i
14、s normally carried out through ISO technical committees. Each member body interested in a subject for which a technical committee has been established has the right to be represented on that committee. International organizations, governmental and non-governmental, in liaison with ISO, also take par
15、t in the work. ISO collaborates closely with the International Electrotechnical Commission (IEC) on all matters of electrotechnical standardization. International Standards are drafted in accordance with the rules given in the ISO/IEC Directives, Part 2. The main task of technical committees is to p
16、repare International Standards. Draft International Standards adopted by the technical committees are circulated to the member bodies for voting. Publication as an International Standard requires approval by at least 75 % of the member bodies casting a vote. Attention is drawn to the possibility tha

BS ISO 15622:2010ISO 15622:2010(E) ISO 2010 All rights reserved vIntroduction The main system function of Adaptive Cruise Control is to control vehicle speed adaptively to a forward vehicle by using information about: (1) ranging to forward
19、vehicles, (2) the motion of the subject (ACC equipped) vehicle and (3) driver commands (see Figure 1). Based upon the information acquired, the controller (identified as “ACC control strategy” in Figure 1) sends commands to actuators for carrying out its longitudinal control strategy and it also sen
20、ds status information to the driver. ACC control strategy Driver information Detection and ranging of forward vehiclesAcquisition of driver commands Subject vehicle motion determination Actuators for longitudinal control Environment Vehicle Driver Figure 1 Functional ACC elements The goal of ACC is
21、a partial automation of the longitudinal vehicle control and the reduction of the workload of the driver with the aim of supporting and relieving the driver in a convenient manner. This International Standard can be used as a system level standard by other standards, which extend the ACC to a more d
22、etailed standard, e.g. for specific detection and ranging sensor concepts or higher level of functionality. Therefore, issues like specific requirements for the detection and ranging sensor function and performance or communication links for co-operative solutions will not be considered here. BS ISO

24、 requirements, basic driver interface elements, minimum requirements for diagnostics and reaction to failure, and performance test procedures for Adaptive Cruise Control (ACC) systems. Adaptive cruise control is fundamentally intended to provide longitudinal control of equipped vehicles while travel
25、ling on highways (roads where non-motorized vehicles and pedestrians are prohibited) under free-flowing traffic conditions. ACC can be augmented with other capabilities, such as forward obstacle warning. 2 Normative references The following referenced documents are indispensable for the application
