The client is a global manufacturer of automotive components, a Tier 1 supplier to major OEMs around the world. They were entrusted with developing numerous modules within the major ECU’s of an OEM’s set of new generation vehicles. The main ECUs involved were the Body control module (BCM) and Enhanced lighting module (ELM) of the vehicle. 

BCM is the master module which handles the major cabin controls of the vehicle whereas ELM controls mainly the lighting of the vehicle. A BCM in automotive can perform a wide range of functions such as Passive Entry Passive Start (PEPS), Remote Keyless Entry (RKE), Climate Control System, Power Windows etc 

We got on board the project due to our extensive experience in Vehicle Electronics. Our team of experts extended their support in designing, developing, and testing the Complex Device Drivers for their Body control ECMs. 

We worked on the device driver layer and the Hardware abstraction layer (HAL) of these ECUs. The Hardware abstraction layer (HAL) acts as an interfacing layer between the hardware and the rest of the ECU software.  ADC, CAN, DIO, FLS, GCL, ICU, LIN, MCU, PORT, PWM, SPI, WDG are some of the modules that we develop.   

In Turn, the application layer, which is responsible to use the released work products, was developed by the OEM.
