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 ISO/IEC 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. ISO 17386 was prepared by Technical Committee ISO/TC 204, Intelligent transport systems.

Manoeuvring aids for low speed operation enhance safety and driver convenience during parking or manoeuvring situations at very low speed, e.g. in narrow passages. Drivers can avoid collisions with obstacles that cannot be seen but can be detected by the system and they can make more effective use of limited parking space. Manoeuvring Aids for Low Speed Operation (MALSO) are detection devices with non-contact sensors which assist the driver during low speed manoeuvring. MALSO systems indicate to the driver the presence of front, rear or corner objects when squeezing into small parking spaces or manoeuvring through narrow passages. They are regarded as an aid to drivers for use at speeds of up to 0,5 m/s, and they do not relieve drivers of their responsibility when driving the vehicle.

It specifies minimum functionality requirements which the driver can generally expect of the device; i.e., detection of and information on the presence of relevant obstacles within a defined (short) detection range. It defines 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. MALSO systems use object-detection devices (sensors) for ranging in order to provide the driver with information based on the distance to obstacles. The sensing technology is not addressed; however, technology affects the performance-test procedures set up in this International Standard (refer to Clause 7). The current test objects are defined based on systems using ultrasonic sensors, which reflect the most commonly used technology at the time of editing this International Standard. For other sensing technologies possibly coming up in the future, these test objects shall be checked and changed if required. Visibility-enhancement systems like video-camera aids without distance ranging and warning are not covered by this International Standard. Reversing aids and obstacle-detection devices on heavy commercial vehicles are not addressed by this International Standard; requirements for those systems are defined in ISO/TR 12155. 2 Normative references The following referenced documents are indispensable for the application of this document.

Visual information and warning may be used as a supplement. A standardized information strategy will be the basis for the development of both types of information components, as this makes the use in different vehicles easier and safer. The most relevant information for the driver is the distance, i.e. the clearance, between the vehicle boundary and an obstacle. The location of the obstacle relative to the vehicle may be indicated as additional information. Failures shall be indicated to the driver as well. A general information strategy cannot be established because of the following reasons. There are many different ways of coding the information. Each car manufacturer will integrate the manoeuvring aids into its driver-information system with its specific driver interface. The following subclauses may be regarded as guidance in the implementation of an information strategy.

The following basic code is recommended for the audible information channel. a) Distance shall be coded into at least two levels. These zones may be represented by different repetition rates, with the basic rule that a high repetition rate or a continuous sound corresponds to short distances. If a different or an additional code is used it should not interfere with the basic rule. b) The different areas may be represented by different carrier frequencies (e.g. high frequency for the front, low frequency for the back of the vehicle). In this case, not more than two different areas/carrier frequencies should be used. Synthesized or recorded voice messages may also be used. c) The activation/deactivation of the system and the indication of failure/disturbance may be presented by an audible signal, clearly distinguishable from the other signals. 5.2.3 Visual information The visual information shall be presented in accordance with ISO 15008. If the visual information channel is used as a supplement to the audible channel, the following basic code is recommended. a) The information shall be coded into at least two levels, represented by different colours: red for level 1 (imminent collision level) and yellow or green for level 2 (attention level). If a different code or an additional advisory level is used, it should not interfere with these basic code elements. The two levels may be subdivided by using more than one display element with the same colour, e.g. a bar-graph with three red and three yellow bars, allowing for six sub-levels. Figure 3 shows the warning levels for the rear monitoring range.

For example, it is recommended to place the display for the rear monitoring range in the rear part of the passenger compartment, because this allows drivers to watch the display while simultaneously looking through the rear mirror or over their shoulder directly through the rear window. For the same reason, it is recommended to locate the display for the front monitoring range in the dashboard. c) It is recommended to indicate the activation/deactivation and malfunction of the system by a telltale or a symbol in all active displays of the system. These symbols shall be in accordance with ISO 2575. 5.2.4 Combination of visual and audible information A combination of visual and audibl
