BCM

Body Control Module

Engineered by T-Engineering AB, this robust solution offers a pre-configured, high-performance control unit with our in-house developed Autosar platform. It eliminates the need for ground-up development while maintaining the flexibility to scale as your vehicle’s features grow.

 

It represents a low-cost solution while still offering an exceptional range of body functionality.

 

By choosing T-Engineering’s standard BCM, you gain a production-ready integration node equipped with a secure bootloader. Moving directly to a production-capable ECU,  with minimal extra effort, allows you to focus your resources on the vehicle’s unique identity rather than basic electrical architecture.

BCM Functions (Basic)

The Standard Configuration provides a comprehensive suite of “Basic” functions essential for vehicle operation:

 

  • Centralized Intelligence: Acts as a CAN Gateway (x6), manages Vehicle Mode Management and Vehicle Network Management.

  • Secure Vehicle Access: Integrated Remote Keyless Entry (RKE) and Authentication/IMMO using high-security protocols.

  • Exterior & Interior Lighting: Complete control over drive lights, hazard/turn signals, and high-side driven LED or bulb configurations for everything from low beams to license plate markers.

  • Total Visibility: Intelligent management of front wiper control, washer pumps, and heated windows/mirrors.

BCM Function Selection & Scalable Integration

The system is highly flexible; for instance a single BCM can control four power windows and one 4-way seat, or two power windows and two 3-way seats.

Since internal relays drive windows and seat motors, you can choose a configuration that best fits your vehicle’s interior layout. Here are three standard ways to utilize a single BCM:

Easy BCM ECU Configuration with Apptool

 

With a few simple key strokes, Apptool transforms our ‘Off the Shelf’ hardware into your Custom Solution. It bridges the gap between Tier1 reliability and the agility required by low-volume innovators.

Apptool ensures Instant Function Allocation that effortlessly configures the BCM’s 233-pin interface to match your specific hardware layout, whether you are running a two-window/two-seat setup or a four-window utility configuration.

Apptool quickly set parameters for enabling functions (e.g. Anti-Theft triggers and Post-Crash Unlock) ensuring your vehicle meets global vehicle standards.
