GEM BCM Introduction

1 Outline

BCM is mainly used to control the body door lock module, window module,

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

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

functions, and support wireless remote control key, IMMO base station interface, tire

pressure detection, power distribution control and other functions, and integrated

keyless entry, one-button start, window controller and gateway function..

3 Technical performance

3.1 Main function

The main functions of the body controller are: central door lock control, remote

key control, wiper washing control, external light control, interior light control, tire

pressure detection, power distribution control, power saving mode, burglar alarm and

alarm control, wireless key remote control Receive function and CAN network

communication, LIN network communication, diagnosis, keyless entry, one-button

start, window controller and gateway function

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.

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.

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.

6 Installation requirements 6.1 Installation location In order to meet the BCM requirements for temperature, vibration and dustproof and waterproof, UAES recommends installing the BCM in the cockpit (do not install in the engine compartment). If the OEM wants to install the BCM in another location, the installation location should be evaluated by the UAES engineer and the OEM’s engineer.

. In order to protect the BCM and its harness from assembly and damage during assembly, the BCM and other components in the passenger compartment should have sufficient space; 7. Avoid installing BCM where oil, moisture and water droplets are easily spilled; 8. BCM harness should be fixed firmly to avoid supporting the harness through BCM. At the same time, the BCM harness shall be arranged to prevent and protect all the wires in the harness from damage due to wear and overheating; 9.

temperature measured at 2 cm from the front of the entire enclosure shall be such that the maximum permissible temperature limit (85 °C) and the minimum permissible temperature limit (-40 °C) shall not be exceeded under any extreme environmental conditions. 6.4 Vibration and shock requirements The fittings and mounting bolts used to assemble the BCM shall withstand the maximum vibration and shock that can be generated at the installation location.

Figure1 Angle of installation The installation angle recommended by UAES, in the vertical direction, allows the installation angle to be 20° to 90°, as shown in Figure 1. If the installation direction and angle are outside the recommended range, the UAES’s engineers and the OEM’s engineers will need to make an assessment.

to the BCM bottom plate. Otherwise, the sensitivity of the RKE will be affected. If the installation position is determined, Changes must be confirmed with the UESA engineer. If other materials are used, the customer must ensure that the BCM meets the requirements for vibration, heat dissipation, temperature, and EMC. If there is any deviation, it must be confirmed with UAES. 6.

exceed 2m, it is recommended to separate the line. If the customer chooses a wire harness connector other than the recommended one, it needs to negotiate with UAES to determine. 7.2 User guide BCM applications must meet the following requirements： In the process of vehicle assembly, sparks caused by static electricity may cause BCM damage.

the pulse peak and pulse width are large enough, it may cause damage to the BCM. Therefore, please confirm that the avalanche diode is installed inside the generator for protection, and the avalanche voltage is lower than 35 V. (1) Load Dump refers to the disconnection of the battery from the generator due to corrosion of the power line during the operation of the generator. 8 Fault analysis and elimination The fault diagnosis protocol is determined by the customer and the UAES.

package to avoid damage to the BCM. Care should be taken when unpacking to avoid scratching the BCM. Special care should be taken when transporting inside the plant to avoid damage and contamination of the BCM. 11.3 Content of check a) Check if the BCM label meets the requirements; b) Check the BCM housing for obvious physical damage; c) Check the BCM pins for physical damage.
