An Intelligent, Auxiliary Controller for Offroad Vehicles

Jeep Accessories | Projects 0 No Comments

Control up to five auxiliary accessories in the vehicle (up to 15A each, or 45A total) using standard, replaceable Bosch-style relays.  Control via remote control interface (Linux) over RS485 or via standard switches.  Atmega328p processor and custom bootloader makes it possible to program via Arduino IDE over RS-485 bus.  Uses the MoCoBus libraries I developed for Dynamic Perception for rapid protocol development.  GUI written in Qt.  Will release all files and code open-source when done.

Additional Features:

  • Battery Voltage Monitoring
  • Self-Regulating Temperature with DC fan control
  • Optical isolation between relays and CPU
  • Fail-safe aux control with mechanical switches
  • All relays in off-state during power-up
