washing module, wiper module, interior light module, external light module, IMMO

base station interface module, wireless key remote control receiving module, tire

pressure detection module, power distribution control module, etc. Complete part of

communication and diagnostic functions, and integrate keyless entry, one-button

start, window controller and gateway function.

2 Operating principle

BCM collects various input signals (analog signals, digital signals, pulse signals,

etc.) and controls the output of loads such as door locks, windows, car washes,

wipers, interior lights and exterior lights according to the requirements of the body

GEM BCM Introduction

control function. Through CAN, LIN to complete communication and diagnostic

3.2 main technical parameters

3.2.1 Shape structure

The platform GEM housing material is plastic, and the outer surface of the housing

does not require special trimming and treatment.

The external structure of the platform GEM shell is installed as follows (excluding the

BCM connector female end):

Size：length ：222.2 mm±2 mm width：154.1 mm±2 mm height：76.7 mm±2 mm.

GEM The product identification label is attached to the upper right position of the BCM

cover. The label represents customer information, version index number, barcode, serial

number and other information.

3.2.2 Electrical characteristic parameter

a) Operating Voltage:

Full-function operating voltage range： 9 V ～16 V

Functionally limited voltage range： 6 V ～ 9 V,16 V ～ 24 V

Guaranteed diagnostic function voltage range： 9 V ～ 16 V

b) Overvoltage protection:

The BCM can withstand an overvoltage of 24 V ± 0.2 V for 60 seconds (ambient

temperature is 23 °C ± 5 °C, other connections are correct), and if the system returns

to normal operating voltage within 60 seconds, the BCM can still guarantee normal

operation.

c) System reverse voltage protection:

The BCM can withstand a reverse voltage of 14.0 V for 10 minutes (23 °C ±

5 °C). If the system returns to normal operating voltage within 10 minutes, BCM can

still guarantee normal operation.

d) Battery power line contact and Auxiliary battery jump start warning:

If you need an auxiliary battery to jump start the vehicle during use, follow the jump

start request: Connect the start voltage ≤24 V, time≤60 seconds.

3.2.3 Mechanical property parameter

a) Vibration Resistance Characteristics：：：：

Under wide-band random vibration conditions, BCM has the same magnitude of

vibration in the x, y, and z directions. The total average acceleration is 19.6 m/s, 27

hours per axis, and the temperature range is -40 °C to 85 °C.

b) Temperature characteristic parameter：：：：

Storage temperature： -40 ℃ ～ 90 ℃

Operating temperature： -40 ℃ ～ 85 ℃

c) Waterproof and dustproof grade：：：：

IP5K0 (DIN40050-9)

d) product quality：：：：

GEM LV2：Upper cover：163 g Bottom plate：135 g label：0.01 g PCBA：207g ,

total weight：505 g

4 ISO26262 functional safety requirements

ISO26262 functional safety is an international standard for passenger cars designed

to prevent the risk of potential electrical and electronic system failures. In general, the

functional safety requirements are defined by the development interface protocol DIA

（Development Interface Agreement）agreed between the customer and the UAES. If the

parties do not sign the agreement, the functional security definition is executed by default

according to the UAES standard.

Functional safety level of power distribution control,KL15-1(IGN1) and KL15-2(IGN2)

control level is ASIL B;KL50 control level is ASIL A.

The functional safety level of the brake light is ASIL B.

The functional safety level of the dipped headlamp is ASIL B.

The functional safety level of the wiper is ASIL A.

The functional safety level of the window controller is ASIL-A.
