3 Terms and definitions
For the purposes of this document, the terms and definitions given in GB/T 29259 and GB/T 39267 and the following apply.
3.1
protective function
function of preventing the unauthorized use of a vehicle or function of tracing positioning information when the unauthorized movement of a vehicle occurs
3.2
protective device
device designed to prevent the unauthorized use or movement of a vehicle, in the following two forms:
——locking device;
——locking device and positioning device
3.2.1
locking device
device installed on a vehicle for locking the steering or the transmission mechanism of the vehicle
3.2.2
positioning device
device installed inside a vehicle to collect and report the positioning information of the vehicle and to realize the protective function in case of the unauthorized use or movement of the vehicle
3.3
steering
steering control mechanism (handlebar or steering wheel), steering column, steering link plate, and all steering components that directly affect the effectiveness of the protective device
3.4
combination
various combinations of specially designed and manufactured locking systems
3.5
mechanical key
mechanical component used for locking and unlocking only one or more locking systems on the same vehicle
3.6
electronic key
component used for communicating with one or more terminals on a vehicle, where the communication results can directly or indirectly lock and unlock one or more locking systems on the same vehicle through the control module
Note: Only applicable to the manufacturer's onboard components when the vehicle leaves the factory for the first time.
3.7
positioning
process and technique for determining the location of a user using measurement information
[Source: GB/T 39267-2020, 2.1.2]
3.8
circular error probable; CEP
radius that includes 50% of the two-dimensional scattered points, with the true value as the center in a certain plane
[Source: GB/T 39267-2020, 5.1.17]
3.9

electromagnetic phenomenon that vehicles, electrical and electronic systems/components resist electromagnetic disturbance and avoid performance degradation
[Source: GB/T 29259-2012, 3.8]
3.10
reporting function
function of reporting positioning information at a fixed cycle according to an established protocol
3.11
elevation mask angle
minimum elevation angle threshold of a satellite set by the receiver for signal reception or navigation solution
[Source: GB/T 39267-2020, 5.3.37]
3.12
original component
components that are installed on the vehicle as it leaves the factory
4 Classification of locking devices
Locking devices are classified into four categories.
——Class I: Those that only lock the steering.
——Class II: Those that can lock the steering and prevent the engine or motor from starting.
——Class III: Those that preload to lock the steering and prevent the engine or motor from starting.
——Class IV: Those that lock the transmission mechanism.
