Real-World Use Case

Building a Distributed BCM with SmartWheels Mini

Each body subsystem runs its own dedicated SmartWheels Mini ECU — preconfigured with the right Stamp I/O for that actuator. All nodes communicate over a shared CAN bus, forming a distributed Body Control Module (BCM) architecture without a bulky centralised ECU.

Stamp Configuration

Right Stamps for Each Actuator

Each Mini ECU node picks the exact Stamp combination for its load type — no over-engineering, no unused pins.

ORVM & Power Windows
Stamp1 – Input
Mixed I/O — 4 Digital + 4 Analog
Mirror/window switch states (PNP/NPN)

H-Bridge Outputs (2ch × 4A)
Bi-directional motor drive for mirror tilt & window up/down
Overcurrent + shoot-through protection built in
Wiper Control
Stamp1 – Input
8 Digital Inputs (Pull-down)
Wiper stalk positions + park sensor
Stamp2 / Stamp3 – Output
Full H-Bridge (2ch × 4A) + PWM
Wiper motor speed via PWM duty cycle; reverse for park-home
Motor stall detection + thermal shutdown

High-Side Power Outputs (4A/ch)
Low/High beam, indicators, DRL + PWM levelling
Open-load, short-to-GND & short-to-VBAT detection
Hardware Protection

Full Load Protection on Every Output

Every output Stamp ships with automotive-grade protection — no external components required.

Overcurrent Protection
Per-channel current limiting; latch-off on sustained fault with auto-retry
Thermal Shutdown
Junction temperature monitoring; gate driver shuts off before damage
Short-to-GND / VBAT
Diagnostic flag on High-Side and H-Bridge outputs; status reported over CAN
Shoot-Through Guard
Dead-time insertion on H-Bridge half-bridges prevents simultaneous high/low conduction
Ready-Made Subsystem Kits

Don't want to build from scratch?
Pre-configured BCM kits are available.

ANCIT offers the complete Programmable Vehicle Subsystem Kit — each subsystem (ORVM, Power Windows, Wiper, Adaptive Headlight, Instrument Cluster) ships as a plug-and-play unit with its Mini ECU pre-flashed and Stamp-configured. Ideal for OEM validation, university labs, and R&D benches.
