ISO 22078-2020 pdf free.Intelligent transport systems — Bicyclist detection and collisionmitigation systems (BDCMS) — Performance requirements and testprocedures.
1.This document specifies the concept of operation, minimum functionality, system requirements, systeminterfaces, and test procedures for bicyclist detection and collision mitigation systems (BDCMS).It alsodefines the system test criteria necessary to verify that a given implementation meets the requirementsof this document.Implementation choices are left to system designers, wherever possible.
BDCMS are fundamentally intended to provide emergency braking(EB) of equipped vehicles in orderto mitigate collision severity between the subject vehicle (SV) and a bicyclist. BDCMS detect bicyclistsforward of the SV, determine if the detected bicyclists are in a hazardous situation with respect to theSV, and initiate EB if a hazardous situation exists and a collision is imminent. Systems that include othercountermeasures such as evasive steering are outside the scope of this document.
This document defines two types of BDCMS (based on operation in different ambient illuminance) andtwo classes of BDCMS (based on operation on different vehicle size classes), as depicted in Table 1.Thisdocument does not apply to motorcycles. The operational design domain is public roads.BDCMS is notintended for off-road use.
2.Normative references:The following documents are referred to in the text in such a way that some or all of their contentconstitutes requirements of this document. For dated references,only the edition cited applies.Forundated references, the latest edition of the referenced document (including any amendments) applies.
3.bicyclist:human-vehicle combination consisting of a human riding on top of a two-wheel frame (bicycle) with asteering mechanism, brakes, two pedals for propulsion (optionally with motor-assisted pedalling) thatdoes not require a licence for use on public roads.
No countermeasures are performed in the BDCMS off state. Upon turning the ignition to the offposition, BDCMS shall transition to the BDCMS off state. Whenever the self-test function determinesthat BDCMS are not able to deliver adequate performance, or when the driver manually turns off theBDCMS (optional), it shall transition to the BDCMS off state. BDCMS may be in the BDCMS off state whenthe vehicle is on.In the BDCMS inactive state, BDCMS shall monitor vehicle speed and determine if it is appropriate toactivate the system.ISO 22078 pdf download.
