3 Terms and Definitions
For the purposes of this document, the terms and definitions given in GB/T 29259—2012 and the following apply.
3.1
electrical/electronic sub-assembly (ESA)
An electrical/electronic device or assembly with associated electrical connections that performs one or more specified functions.
3.2
wiring harness
The power supply cables, bus system (e.g., CAN) cables, signal or active antenna cables installed in a vehicle.
3.3
immunity related functions
Functions related to vehicle safety that are affected by electromagnetic disturbances, mainly including the following:
a) Functions directly controlling the vehicle:
Causing performance degradation or change of certain devices/systems (e.g., engine, drive motor, transmission, braking system, suspension system, steering system, speed limitation device, combined driver assistance systems, and automated driving systems);
Affecting the driver's position (e.g., seat or steering wheel positioning);
Affecting the driver's field of vision (e.g., low beam headlights, wipers, indirect vision devices, forward field of vision assistance systems).
b) Functions protecting the driver, passengers, and other road users (e.g., airbags, safety restraint systems, and emergency call systems).
c) Functions that, after being subjected to electromagnetic disturbances, could cause misinterpretation by the driver or other road users:
Visual signals: such as malfunction of turn signals, brake lights, front position lamps, rear position lamps, hazard warning signal indicators, and false information on warning indicators, signal lights, or displays directly observed by the driver concerning certain functions listed in a) or b);
Audible signals: such as malfunction of anti-theft alarms, horns, etc.
d) Functions related to the vehicle data bus, such as affecting the transmission of data concerning the safety functions of relevant nodes.
e) Functions related to important vehicle indications and recorded data after being subjected to electromagnetic disturbances, such as speedometers, odometers, tachographs, and on-board video driving recording systems.
NOTE: The above content is not exhaustive; immunity related functions are adjusted according to vehicle/technology evolution.
4 Requirements
