About

Advanced BCMs with integrated gateway for optimized energy efficiency

In addition to the classic BCM design, there is a trend towards integrating a gateway function, particularly in the C to F vehicle segments, i.e., from lower-medium to luxury cars.

Infineon enhances the energy efficiency of automotive body control modules with an integrated gateway by replacing relays and fuses with high-side and low-side power ICs, implementing half-bridge ICs for motor control, and utilizing LED drivers. Additionally, supply ICs, system basic chips (SBC), as well as high- and low-speed CAN transceivers minimize current consumption. The Traveo™ T2G microcontroller family provides standby controller capabilities.

Ensuring safety in automotive BCM designs with AURIX™ microcontrollers

Ensuring safety is paramount in the design and implementation of body control modules, as they play a critical role in managing and controlling various vehicle systems. Infineon's AURIX™ TC2xx and TC3xx microcontroller families include a hardware security module (HSM) for enhanced safety. Pressure sensors in tire pressure monitoring systems (TPMS) further contribute to safety.

BCM with integrated gateway for increased connectivity and security

To guarantee the integrity and confidentiality of data transmitted through the gateway, strict security measures need to be implemented.

Infineon's transceivers, receivers, and security controllers are utilized in remote keyless entry (RKE) and passive keyless entry (PKE) systems. For car access, Infineon offers the CC EAL6+ high-certified security controller family SLI37CMxxx, recommended by the Car Connectivity Consortium (CCC).
