Body Control Modules:

Our Customer has a cap on the number of full time in-house specialists it can use at each location. Having reached it at a time of strong demand for Body Control Modules (BCM) software, the only alternative they were left with was to outsource some of the work. A BCM handles communication between Electronic Control Units (ECU) and operates all the required vehicle body functions such as windshield wiper control, exterior and interior light control, central door locking control, and car access.

AROBS Approach:

The BCMs for which the remote team approach was considered needed additional functionality. AROBS was commissioned the task of expanding existing BCMs after a successful pilot project in which 3 AROBS specialists performed mainly testing tasks the different Controls. The team allocated to the customer reached 10 specialists, which are split in groups of 1 to 2 and develop and test software for CAN / LIN communication and control for Wipers, interior heating, exterior lights, centralized locking, alarm. In addition, our specialists performed static analysis on existing code developed by the customer. Some of the features we have been implementing are Safety Critical and consequently undergo intensive testing. The Safety Critical level is assigned to components that can cause human fatalities (e.g. Electronic Steering Column Lock). The code we have been developing for this project is Autosar compliant. For these assignments we have done Ansi C and Model Based Development in MathLab, Simulink, Targetlink, Rhapsody, and Statemate.

Benefits and impact

The components developed by AROBS are already included in car models distributed throughout the world. The acceptance testing performed by the customer and the feedback from car owners are excellent, attesting to the high quality of our services.
