Remote motor vehicle access control unit e.g. electronic badge, localization assisting method for motor vehicle, involves controlling identification code verification and alarm unit activation upon reception of localization request signal

摘要

The method involves controlling the transmission of a localization request signal comprising an identification code and a specific localization request, by utilizing a processing unit (4) or an electronic badge (B). A verification of the identification code is controlled and activation of an audible alarm unit (8) of the electronic badge is controlled, upon reception of the localization request signal. An independent claim is also included for a system for access to a motor vehicle and implementing a method for assisting the localization of a remote motor vehicle access control unit.
