The work of preparing International Standards is 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 part 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 isonEC Directives Part 2 The main task of technical committees is to prepare 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 that some of the elements of this document may be the subject of patent rights. ISo shall not be held responsible for identifying any or all such patent rights so 15622 was prepared by technical committee iso/Tc 204 Intelligent transport systems This second edition cancels and replaces the first edition(Iso 15622: 2002)which has been technically revised O Iso 2010-All rights reserved so15622:2010(E) Introduction 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 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 sends status information to the driver Subject vehicl motion determination Acquisition of driver commands Detection and ranging ACC of forward vehicles control strategy Actuators for Driver in formation longi tudinal control Environment Vehicle Driver Figure 1- Functional ACC elements The goal of ACC is 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 detailed 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 O Iso 2010-All rights reserved INTERNATIONAL STANDARD So15622:2010(E Intelligent transport systems- Adaptive Cruise Control systems- Performance requirements and test procedures s coDe This International Standard contains the basic control strategy, minimum functionality 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 travelling 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 of this document. For dated references, only the edition cited applies.

an electrical brake(when the forces are generated by electro-magnetic action between two parts of the vehicle moving relatively but not in contact with one another); a fluid brake(when the forces are generated by the action of a fluid situated between two parts of the vehicle moving relatively to one another ) an engine brake( when the forces are derived from an artificial increase in the braking action, transmitted to the wheels, of the engine) Iso 2010-All rights reserved so15622:2010(E) NOTE 2 Adapted from UN ECE Regulation No. 13-H: 1998, definition 2.6 NoTE 3 For the purposes of this International Standard transmission control devices are not considered as brakes 34 clearance distance from the forward vehicle's trailing surface to the subject vehicle's leading surface 3.5 Conventional cruise contro system capable of controlling the speed of a vehicle as set by the driver 3.6 forward vehicle vehicle in front of and moving in the same direction and travelling on the same roadway as the subject vehicle 3.7 free-flowing traffic smooth-flowing and heavy traffic excluding stop and go and emergency braking situations 38 time gap value calculated from vehicle speed v and clearance c by: t=chi C 3.9 set speed desired travel speed, set either by the driver or by some control system that is external to the Acc system NoTE The set speed is the maximum desired speed of the vehicle while under ACc control 3.10 steady state condition whereby the value of the described parameter does not change with respect to time, distance, etc 3.11 subject vehicle vehicle equipped with the system in question and related to the topic of discussion 3.12 ACC system states For the purposes of this International Standard, three system states are distinguished (see Figure 2) 3.12.1 ACC off state state in which direct access for activation of "acc active state" is disabled 3.12.2 AcC stand-by state state in which there is no longitudinal control by ACC system and the system is ready for activation by the driver O Iso 2010-All rights reserved so15622:2010(E) 3.12.3 ACC active state state in which the system controls speed and/or clearance 3.12.3.1 ACC speed control sub state state in which the system controls the speed according to the set speed 3.12.3.2 ACC following control sub-state state in which the system controls the clearance to the target vehicle according to the selected time gap 3.13 target vehicle vehicle that the subject vehicle follows 3.14 stationary object object in front of the subject vehicle which is stationary 4 Symbols and abbreviated terms 4.1 Symbols See Table 1 Table 1- symbols and meanings Symbol Meaning A Utilized area, general for area Illuminated surface alateral max Maximum allowed lateral acceleration in curves min Minimum allowed longitudinal acceleration maximum allowed longitudinal deceleration Maximum allowed longitudinal acceleration Maximum allowed acceleration during curve test vehicle max Maximum possible deceleration capability during manual driving Clearance, inter-vehicle distance Distance between object and sensor, general for distance Distance below which detection of a target vehicle is not required Distance below which neither distance measurement nor determination of relative speed is required Distance for measurement purpose dA Distance between source and projected plane A Maximum detection range on straight roads max curve Maximum detection range on curves E Intensity of irradiation out of transmitter 10 Radiated intensity ref Radiated intensity in a given direction Length of a side of a radar test reflector Iso 2010-All rights reserved so15622:2010(E) Table 1(continued) Symbol Meanin g Circle radius, curve radius R circle Actual radius of curve r Minimum curve radius Brake max Minimum time to achieve maximum deceleration Time. start test o42 Time. start manoeuvre Time end manoeuvre t Time. end test True subject vehicle speed over ground Circle Maximum speed on a curve for a given lateral acceleration alateral max v Vehicle speed as it enters a curve of radius R Minimum speed at which automatic acceleration is allowed Vehicle set speed set max Maximum selectable set speed set min Minimum selectable set speed vehicle end Vehicle speed at the end of a test Vehicle max Maximum vehicle speed Vehicle start Vehicle speed at the start of a test Width of fov measured from the centreline at d curve C Half angle of field of view Wavelength of radar wave Time gap between vehicles Emax(v) Maximum possible steady-state time gap at a given speed v max Maximum selectable time gap Minimum steady-state time gap at speed mIn Minimum selectable time gap Radiated power 2 Solid angle Solid angle(of the source) Illuminated solid angle 4.2 Abbreviated terms CTT coefficient for test target for infrared reflectors FOV field of view HDA horizontal detection area Rcs radar cross-section O Iso 2010-All rights reserved 【实例截图】

感谢您为本站写下的评论,您的评论对其它用户来说具有重要的参考价值,所以请认真填写。
- 类似“顶”、“沙发”之类没有营养的文字,对勤劳贡献的楼主来说是令人沮丧的反馈信息。
- 相信您也不想看到一排文字/表情墙,所以请不要反馈意义不大的重复字符,也请尽量不要纯表情的回复。
- 提问之前请再仔细看一遍楼主的说明,或许是您遗漏了。
- 请勿到处挖坑绊人、招贴广告。既占空间让人厌烦,又没人会搭理,于人于己都无利。
