4.13 Before unlocking the device to prevent unauthorized use, the drive

system of the vehicle cannot be started in the normal way.

4.15 For the device to prevent unauthorized use equipped with driver warning

system, when the side door of driver is open, if the device to prevent

unauthorized use does not work or the key is not pulled out, the warning system

shall be triggered immediately.

5.1 Device to prevent unauthorized use acting on steering

5.1.1 The device to prevent unauthorized use acting on steering shall be able

to disable the steering. Before the engine starts, the normal steering function

shall be recovered.

5.1.6 If the component fails when a torque specified in 5.1.4 is applied and

the steering system remains locked, the system shall meet the requirements.

5.2 Device to prevent unauthorized use acting on driving or on braking

5.2.1 The device to prevent unauthorized use acting on driving shall be able

to stop the steering of vehicle drive wheel.

5.2.5 The device to prevent unauthorized use shall be designed and

manufactured so that it shall be still fully effective after it is subjected to 2,500

cycles of locking wear test at each direction. For the device to prevent

unauthorized use acting on braking, the electronic or mechanical sub-parts of

the device shall also meet the requirements. The device to prevent

unauthorized use shall be designed and manufactured so that it shall be still

fully effective after it is subjected to 2,500 cycles of locking wear at each

direction.

5.2.6 If the key of the device to prevent unauthorized use is pulled out of a

position other than the drivetrain lock or brake lock position, it is designed so

that the manual override can reach this position and the key removal shall not

be effected unconsciously.

5.3 Device to prevent unauthorized use acting on shifting

5.3.1 The device to prevent unauthorized use acting on shifting shall not

prevent any change on shift.

5.3.2 For manual transmission, lock the shift lever in the reverse gear position

and also allow the shift lever to be locked in the neutral position.

7.1 The VAS shall signal an alarm when the vehicle is intruded or

unauthorized used. Alarm signal shall be audible signal. In addition, it shall also

include visual warning signaling device or wireless warning device, or the

combination of these devices.

7.4 The installation of VAS in the vehicle shall not affect the performance of

the vehicle (in the unset state) or its normal operation.

7.5 The VAS and its components shall not be accidentally triggered,

especially when the engine is running.

7.6 VAS malfunction or power failure shall not affect the operational safety of

the vehicle.

7.7 VAS, its components as well as the controlled parts shall be designed,

manufactured and installed to stop immediate, accident failure by unauthorized

personnel to the maximum extent, or damage by tools that are cheap, easily

hidden, carried and manufactured by public.

7.10 VAS may include immobilizer. The immobilizer shall meet the

requirements of Clause 15, Clause 16, Clause 17.

8.1 Protection scope

8.1.1 Requirements

VAS shall be able to detect at least any of the doors, bonnet, trunk, and issue

an alarm signal. Failure or shutdown of a light source (such as a passenger

compartment light) shall not affect the control operation. To prevent

unnecessary alarm sounds (false alarm, see 8.1.2), additional information

sensor or display may be used, for example.

8.1.2 Safety measures to prevent false alarms

8.1.2.1 Through appropriate measures, for example.

8.2 Audible alarm signal

8.2.1 General requirements

The alarm signal shall be legible and distinct from the acoustic signals used in

other road traffic. In addition to the original audible alarm, a separate audible

alarm can be installed in the VAS-controlled area of the vehicle to prevent

personnel from entering the vehicle easily and quickly. If the destruction of a

standard audible alarm (which is usually easier to access) does not affect the

operation of an additional audible alarm, the original standard audible alarm

may be additionally activated by the VAS when using the separate audible

alarm required by 8.2.3.1.

8.3 Visual alarm signal (optional)

8.3.1 General requirements

If the vehicle is intruded or unauthorized used, the device shall issue visual

signals as specified in 8.3.2 and 8.3.3.

8.3.2 Duration of visual signal

After the alarm is activated, the visual alarm signal shall last for 25s ~ 300s.

Unset the system alert shall immediately cut off the signal.

8.11 Optional function requirements

8.11.1 Self-test / fault automatic indication

When the VAS is in the set state of warning, the self-test system (fuzzy control)

shall recognize and make an indication of abnormal conditions (for example,

opening of doors, etc.).

9.1 Operating parameters

All parts of the VAS shall work flawlessly under the following conditions.

9.1.3 Weather resistance

It shall be 7 days required by GB/T 2423.4-1993.

min.

9.2 Test conditions

9.2.1 Test running

9.2.2.4 VAS, in setting and unset state, shall withstand (18±0.2)V over-voltage
