Champ d’application

This standard specifies the general and special requirements, as well as testing methods for protective devices against unauthorized use (anti-theft devices) installed in Category M and Category N motor vehicles. It is specifically applicable to the immobilizers used in M1 vehicles and N1 vehicles with a maximum design total mass not exceeding 2000 kg. Manufacturers of passenger cars and light commercial vehicles must ensure their anti-theft systems comply with these regulations. The standard does not apply to vehicles outside these categories or to devices not intended to prevent the unauthorized starting of the engine or other primary power sources.

Exigences techniques

The standard outlines comprehensive technical requirements for various types of anti-theft devices, including mechanical, electro-mechanical, and electronic systems. It mandates that devices must prevent the normal starting of the vehicle's power system and disable steering, transmission, shifting, or braking functions when activated. Anti-theft devices must be designed to resist unauthorized opening using low-cost, easily concealed tools. For electronic and electro-mechanical systems, the standard introduces specific requirements to prevent network attacks and vulnerabilities. It also details requirements for digital keys, including binding to physical carriers, mutual authentication with the vehicle, and measures against replay attacks. Digital key unlocking requires detection within the vehicle or a 6-meter radius around it. The standard specifies stringent requirements for immobilizers, mandating that they must prevent the vehicle from moving under its own power. They must enter the set state automatically under certain conditions, such as when the ignition is turned off and a door is opened, or within 60 seconds of key removal. Immobilizers must also meet specific code variation requirements to prevent scanning attacks. Additionally, the standard includes general requirements for brake locking systems, ensuring that the release of the brake lock does not automatically contradict the driver's intention. It also covers auxiliary devices like acoustic and optical alarms, specifying their duration and activation methods.

Méthodes d’essai

The standard defines several key testing procedures to verify compliance. Wear cycle tests (Appendix A) evaluate the durability of locking systems for steering, transmission, shifting, and braking mechanisms through repeated locking cycles. Strength tests (Appendix B) assess the ability of steering and transmission locks to withstand specified static torques and the performance of brake locks on inclined surfaces. Environmental tests (Appendix C) verify the device's resilience to temperature variations, voltage changes, humidity, reverse voltage, short circuits, and vibrations. Electromagnetic compatibility (EMC) tests (Appendix D) ensure the devices are immune to electromagnetic radiation and electrostatic discharge, and that their radiation emissions are within specified limits, referencing standards like GB 34660-2017 and GB/T 19951.
