I、Summary

（I）Summary of Safety Auxiliary System

Generally, auxiliary restriction system indicates whole safety airbag system, and there are “SRS” marks on trim cover of
airbag or where there are airbags;

1、Driver Airbag - DAB：Directly protect driver’s upper body when serious front collision happened, and it can stop

driver from moving forward in some extent. Usually this kind of airbag is installed inside steering wheel, and trim cover of DAB

is horn cover on steering wheel;

2、Passenger Airbag - PAB：Directly protect passenger’s upper body when serious front collision happened, and it can

stop driver from moving forward in some extent. Usually this kind of airbag is installed inside dashboard of front passenger’s

side, and there are visible type and hidden type;

3、Side Airbag - SAB：Mainly supply extra protection to front driver and passenger. Protect chest of front driver and

passenger and hip of person in vehicle collision side.

△

Caution When driving, please fasten safety belt as required. Protection effect will not be obvious when only using

airbag, and in some sense, using airbag without main restriction system (safety belt) will cause passenger more
harm. Safety airbag is auxiliary device of safety belt, and can’t replace safety belt.

（II）Principle of Airbag System

Operation Condition of Airbag

30°

30°

Front impact with enough strong impact force happened in the area of 30°range of vehicle centerline can make airbag work.

Operating Principle of Airbag System

When vehicle happened collision, collision between vehicle and obstruction is called first collision, which can cause vehicle

speed decrease suddenly; collision between passenger and inner structure of vehicle is called second collision. Before passenger in
vehicle and structure component of vehicle happened second collision, rapidly insert airbag full of air between passenger and inner
structure component of vehicle, and absorb kinetic energy of passenger by airbag breathability and exhausting throttling effect, and
this can slow down violent impact and separate passenger and inner structure component to protect passenger.

Airbag, seat and safety belt constitute vehicle restriction system.

（II）Function Requirement

Wiper System

1. Front Wiper Control

BCM controls wiper motor and water spraying pump by monitoring state of wiper switch and combination switch, and

realizes all working mode of wiper system: front wiper low speed working, front wiper high speed working, front wiper
intermittence working, front wiper closed, front windshield spraying water etc..

1) When ignition switch to “ON”, front wiper controlling switch connects to high speed/low speed/intermittence position,

namely corresponding switch on, thus front wiper performs corresponding action.

2) When wiper switch is in intermittence position, Intermittence regulating time has 5 gears. Intermittence regulating time

shown as below:

When vehicle speed is higher than 60km/h (can equipped with 60km/h or 100km/h, default 60km/h), if use intermittence

mode, reduce 4s on the set time.

Vehicle speed treatment: received signal on network is 15 bits, valid value range is 0x0-0x14D5, ratio coefficient is

0.05625.

3) Wiper high/low speed control: when switch connects to low speed position, low speed relay actuated, motor works in

low speed. If switch connects to high speed, high speed relay actuated, motor works in high speed.

4) When inching switch works, low speed always works.

5) Front spraying water is less than 400ms, wiper not works; when more than 400ms, wiper always work with spraying

water, and then wiping three times after water spraying stopping.

6) Front wiper resetting control: After switch is off, when motor is not running to initial position, BCM not receives

resetting position signal, high speed relay cut off, low speed relay not cut off, and motor continues to work; when motor runs to
initial position, resetting switch is actuated, BCM receives resetting position signal, low speed relay cuts off, and motor stops
running.

84

7) When in intermittence position, water spraying is prior.

8) Wiper high speed running period is 1s, and low speed running period is 4/3s.

Emergency strategy When running, if detecting front wiper resetting switch not change for 18s, it can judge that motor

gets stuck, and close output. At the same time only when ignition switch one circulation of ON-OFF-
ON or wiper switch connect to other switch position from OFF, it can restart wiper.

2. Rear Wiper Control

BCM controls wiper motor and water spraying pump by monitoring state of wiper switch and combination switch, and

realizes all working mode of wiper system: rear wiper and rear wiper spraying water etc..

Rear wiper can be configured to be there is or not by diagnosis, default is open rear wiper.

1）There are only “ON” and “OFF” in rear wiper, and it always wipes in low speed when in “ON”;

2）Rear wiper doesn’t work after rear water spraying switch is on for less than 600ms, rear wiper works a wiper period at

least after the switch is on for 600ms;

3）When spraying water time is more 3s than a wiper period, it wipes a period.

Light Control

1. Keyhole Illumination Light Control

Keyhole illumination is mainly to be convenient to insert key for customer. When key not inserting ignition switch, driver’s

side door is open, keyhole illumination light is on; when turning ignition switch to “ON”, keyhole illumination light will be off,
and after door is closed, keyhole illumination light is on for 10s and then off.

2、Any door is open;

2) When satisfying one of the following conditions, interior light will be off gradually:

1、After undefended successfully, interior light will be on for 30s and then off gradually;

2、When open vehicle door from closed state, interior will be on for 30s, and then off gradually;

3) When satisfying the following conditions, interior light will be off immediately:

1、When open vehicle door from closed state, interior is on continuously, if door is open for more than 15min, interior

will be off immediately;

2、When defended successfully, interior top light will be off immediately, immediately off after defended successfully

is prior to interior light working 30s and then off gradually after undefended successfully;

3、When four doors are closed, ignition switch is in “ON”, interior light will be off immediately;

4) Collision signal detonates interior light on:

1、 When collision signal is effective, interior will be on immediately;

2、After collision signal detonating interior light on, if ignition switch is turned from “OFF” to “ON”, interior light will

be off immediately. Interior light gradually off time is 5.5±0.5s.

3. Day Driving Light Control

Day driving light is to warning when driving in daylight. Day driving light can be configured to be there is or not by

diagnosis, default is open day driving light. Used to enable control of day driving light:

1）When turning ignition switch to “ON”, put down manual brake, position light has no output, then day driving light

will be on;

2）When ignition switch is not in “ON”/ “ST” or manual brake is not pulled up or position light has output, day driving

light will be off;

4. Position Light Control

Position light is to shown width and indicating. Position light has high and low configuration.

Low Configuration:

When ignition switch is in any position, position light switch input is effective or automatic light requesting position light
on, position light, license plate light and backlight output is on; when position light switch input is ineffective and automatic
light requesting position light off, position light, license light and backlight output is off.

When position light switch input is still effective, if left front door is open, pull out key, small light will be off immediately;
if left front door is closed, pull out key, small light will not be off; left front door open, small light will be off, and it will be
on when key inserted.

High configuration (with PEPS) :

When ignition switch is not in OFF, position light switch input is effective or automatic light requesting position light on,
position light, license plate light and backlight output is on; when position light switch input is ineffective and automatic
light requesting position light off or ignition switch is in OFF, position light, license plate light and backlight output is
closed.

5. Rear Fog Light Control

Rear fog light is mainly to warning in foggy weather. Rear fog light will be on when satisfying the following conditions:

Open Condition:

Ignition switch is in “ON”, at least one of front fog light, low beam light or high beam light is on, and rear fog light

(transient state) is effective.

Closed condition:

1）When position light is off or rear fog light switch is off, rear fog light is off;

2）Ignition switch is turned to other position except “ON”;

4. Emergency Strategy

States of rear fog light are the same before and after starting.

6. Front Fog Light Control

Front fog light is mainly to warning in foggy weather. Front fog light can be configured to be there is or not by diagnosis,

default is open front fog light.

1） When ignition switch is in “ON” and position light is on, press front fog light switch to open front fog light. Front

fog light switch is normal state switch;

2） When position light is off or front fog light switch is closed or ignition switch is turned to other position except
“ON”, front fog light will be off.

7. High Beam Light Control

High beam light is mainly to illuminate distance in night.

To BCM, overtaking light and high beam light uses one input, in which overtaking light can mechanism automatically

return. High beam light function description are shown as below:

1) When ignition switch is in ‘ON”, and low beam light switch is on or [automatic light switch is on and BCM judging it

is night through value of sunshine sensor] (even low beam light is not on), BCM output high beam light enable low
effective signal, the signal connect back to high beam light switch through wiring harness;

2) When ignition switch is in “ON”, and high beam light enable signal is effective, open high beam light switch, high

beam light is on;

3) When high beam light switch is closed, or ignition switch is not in “ON”, or high beam light enable signal is
ineffective, high beam light is off;

4) Anytime, when high beam light is on, low beam light is on at the same time. Whether high/low beam light is on at the

same time can be decided by configuration, default is high/low beam light on at the same time.

8. Low Beam Light Control

Low beam light is mainly to illuminate vicinity in night. Front headlight mechanism structure is: when turning to low beam

light, position light switch is on.

BCM Device

BCM Device

86

Low beam light function is described as below:

1) When ignition switch is in “ON”, and BCM detecting low beam light switch input is effective, low beam light is on.

2) When ignition switch is in “ON”, and BCM detecting low beam light switch input is effective and automatic light
requesting headlight on, low beam light is on.

3) When ignition switch is in “OFF”, overtaking light switch turned from “ON” to “OFF” denotes the function of

“taking me home”, one ignition circulation denotes one “taking me home” function, enable the function of “taking
me home” again when ignition state turned to “OFF” next time, low beam light is continuously on for 30s.

4) When ignition switch is in “ON”, and low beam light switch is on or [automatic light switch is on and BCM judges

it is night by value of sunshine sensor] (even low beam light is not on), BCM output high beam light to enable
effective signal, the signal connects to high beam light switch by wiring harness.

When in the condition 1 above, low beam light is closed when detecting corresponding low beam light switch is closed.

When in the condition 2 above, low beam light is closed when automatic light switch is closed or request signal is valid.

When in the condition 3 above, low beam light is closed when time is up or ignition switch is turned to “OFF”.

Note: Automatic light request signal is valid indicates light “AUTO” is valid, sunshine signal gets up to light threshold value
requirement. For automatic light strategy please refer to “automatic light”.

9. Automatic Light Control

Function of automatic light is to lit position light and low beam light when light outside is dark and light control switch is in

automatic position. Automatic light function gets to know outside condition by sunshine sensor.

Two EEPROM can be equipped with threshold

AutolampDay_Cfg: range is 0-5V, initial value is 1.8V (specific corresponding initial threshold is supplied by sensor),
AutolampNight_Cfg: range is 0-5V, initial value is 1.2V (specific corresponding initial threshold is supplied by sensor).

1. When BCM power on to initialization, default the night;

2. When input voltage of automatic light sensor is higher than AutolampDay_Cfg, judge it is daytime;

3. When input voltage of automatic light sensor is lower than AutolampDay_Cfg, judge it is nighttime;

10. Brake Light Control

Brake light is mainly to lit the light when braking. When ignition state is in any position, braking switch is valid or braking

request on network is valid, thus open brake light and high position brake light, brake light and high position brake light are
controlled partly.

When in normal mode, brake light and high position brake light can both open through MCU control or brake switch

control.

When in limphome mode, brake light and high position brake light should can be controlled by brake switch.

11. Turning light and Hazard Warning Light

Turning light mainly consists of left front turning light, left side turning light, left rear turning light, left turning indicating

light, right front turning light, right side turning light, right rear turning light, right turning indicating light. When working,
turning light twinkles with the frequency of 90±10 times per minute. Time of on and off are the same. Left front turning light, left
side turning light and left rear turning light merge one way output, right front turning light, right side turning light and right rear
turning light merge one way output, and left turning indicating light and right turning indicating light transmit to meter by CAN.

1） When ignition switch is in “ON”, turning switch is connected or disconnected, thus corresponding turning light twinkle

or closed, and at the same time denotes or connect to tell-tail light on dashboard and flashlight relay twinkle and tweet in the
same frequency;

2） When turning light switch is turned to left or right, BCM drive corresponding turning light to activate to twinkle 3

times at least;

3） When turning light is closed after activating, turning light will be closed after completing its incipient minimum three

times twinkle periods.

4） When turn turning light switch from left to right after left turning light is activated, left side turning light will be off,

and right side turning light will be on.

5） When turn turning light switch from right to left after right turning light is activated, right side turning light will be off,

and left side turning light will be on.

6） Hazard warning light includes two side turning light, key in any position all can drive these turning lights to warning,

corresponding switch is self-lock switch.

BCM Device

BCM Device

87

7） When ignition switch is in “ON”, warning light is prior to turning light, specified instruction are shown as below: if

turning light is on, open warning light switch, then warning light is on instead of turning light, and system gets back to
turning light on state until warning light switch is off; if warning light is on, turn turning light switch to left or right, then
turning light is on instead of warning light, and system gets back to warning light on state until turning light output is closed
or ignition switch is turned from “ON” to “OFF”.

8） If receive collision signal, all lights work at least 5s in warning light state, and pressing warning light switch again after

5s will close warning light, which is to prevent warning light switch being pressed due to collision; when detecting ignition
switch is turned from “ON”-“OFF”-“ON”, collision is removed, warning light recover to normal work.

9） When turning light reports fault due to short circuit to grounding or overload, short circuit state will be recorded to

memory through relevant DTC, and disconnect the side turning light high side drive core immediately, turning indicating
light on combination meter will be off; if turning light is on again and don’t carry out corresponding operation during this
time ignition circulation, must restart ignition switch once (ignition switch ON-OFF-ON), thus output can recover to normal.

10） When working in turning light working mode, some side turning light reports fault due to open circuit or short circuit

to power supply, open circuit state will be recorded in memory through relevant DTC, and the side turning light will twinkle
with double frequency, turning indicating light on combination meter will twinkle with double frequency. Must restart
ignition switch once (ignition switch ON-OFF-ON), thus output can recover to normal; or open circuit fault is removed
during this time ignition circulation, which can recover to twinkle with normal frequency.

Note: Parts marked red indicate that it can close warning light signal after collision signal happened 5s.

12. Power Saving Control

It is mainly to save battery power.

1）If detecting any signal change when BCM is in “OFF”, connect power saving relay immediately, and recover supplying

power:

· Any door state signal of four doors

· Remote control unlock signal

· Central control unlock signal

· Ignition state signal

· Mechanism key unlock signal

2）After connecting power saving relay, all signals above don’t change, thus close power saving relay after 15 min.

3）After connecting power saving relay, detecting any signal above changing again, thus start 15 min timing again.

4）When ignition switch is in “ON”, “ACC”, “START”, power saving relay is always actuated.

5）After BCM getting into dormancy, close power saving relay.
