This project was done in support of a project the university was doing converting
a mini to an EV. The project involved writing software and creating a protocol
for can bus to create a car auto wiper system and create a foundation for other
electronic systems in a car. The scope of the project was to create a test bed
simulating outputs and inputs from a simulated weather sensor and user interface
to a controller to the wiper motor controller.
The image shows the testbed bord where each microcontroller represents a node in
the can control system of the car. The buttons simulate inputs and the LEDs and
led show outputs.
A big part of this project was testing and validation. The image on the left
shows the test bord hooked up to 150m of ethernet cable to simulate the log cable
runs that you would expect in the body of a car. Another part of the project was
the software testing where all input combinations were tested to validate that
they produced the expected output.
The findings of my project are presented here:
