ISO 17386:2004 for Manoeuvring Aids for Low Speed Operation addresses light-duty vehicles, e.g. passenger cars, pick-up trucks, light vans and sport utility vehicles (motorcycles excluded) equipped with such MALSO systems. 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. The current test objects are defined based on systems using ultrasonic sensors, which reflect the most commonly used available technology.
Visibility-enhancement systems like video-camera aids without distance ranging and warning and reversing aids and obstacle-detection devices on heavy commercial vehicles are not covered by ISO 17386:2004.
