Scalable and flexible automotive qualified products allow you to quickly change your scope to meet new design requirements and follow trends.
While there are occasional enhancements and improvements, body applications for driver and passenger comfort and convenience tend to not change rapidly. The biggest challenge: finding solutions that are highly scalable and flexible. Products with these characteristics can easily accommodate low and high levels of functions in a broad range of vehicles. What’s more, scalable and flexible products allow you to quickly change your scope to meet new requirements and follow trends. Cost-effective solutions are also warmly welcomed – so long as they perform and are of high quality. Functional safety is another aspect to always bear in mind.
The Body Control Module, also known as BCM, is an Electronic Control Unit (ECU) specialized for actuating, monitoring, and controlling the vehicle body functions and related ECUs. The BCM communicates with other car functions via the vehicle bus system and can include a Gateway function.
The most common classical vehicle body functions where the BCM plays an important role are:
- Exterior and interior lighting
- Cabin comforts like air conditioning and seat comfort
- Front and rear window wiper and defrost
- Auxiliary Heating like PTC Heater and park heating
- Window lift, power doors, sunroof, rooftop, power lift-gate, and trunk opener
- Car access, central locking, and immobilizer
Body Control Module complexity has increased significantly over the years based on the new features and functions being added. In some vehicles, there are more than 100 loads to actuate, monitor, and control resulting in splitting the BCM functionality into two or more modules such as a front and rear BCM.
To reduce the vehicle BCM and wire harness complexity, functions in the same area of the car have been combined into dedicated Electronic Control Units supplied, monitored, and controlled by the BCM. Examples are LED Modules, HVAC (Heating, Ventilation, and Air Conditioning) Module, Seat Module, Door Module, and Car Access and Immobilizer Module. This kind of body control modularization is often called decentralized body control architecture, and it can include a part of the power distribution and in-vehicle network functions.
