Open source based peripherals for automotive electronic control unit

Abstract

The aim was to develop an embedded system for educational purposes with functions of emulation of some peripherals which are intended for automotive electronic stability control unit (ESC ECU). Emulators of two key ECU peripherals were developed: one for four wheel speed sensors (both two and three current levels types) and second for electronic parking break (EPB) switch based on LIN bus. As real-time processors the Arduino Micro platform was chosen. The up level information system architecture is based on the web server (Raspberry Pi 3 platform) and web browser client and programming was done with JavaScript language for the client (AngularJS framework) and also for server (Node.js).
