Scope and Goals

Over the past decade, much of the hands-on connected and probe vehicle educational opportunities have been concentrated at universities and companies with large research efforts and specialized instrumented fleets. As connected and autonomous vehicle implementation moves forward, it is critical to develop educational laboratory facilities that are broadly accessible to all universities, and perhaps STEM oriented pre-university classes.

Most modern vehicles are now equipped with an extensive suite of sensors that are accessible via an on-board CAN network (https://en.wikipedia.org/wiki/On-board_diagnostics ). This CAN network provides access to important sensors such as three-axis accelerometers, brake pedal pressure, windshield wiper status, turn signal indicators, defroster, traction control, anti-lock brakes, and many other parameters. Examples youtube videos illustrating these sensors can be seen at: https://tinyurl.com/can-bus-demo.

Topics of Interest

• Critical connected and probe vehicle concepts needed for integration of active learning modules into educational curriculum at both the pre-college and college level.
• Identifying appropriate OBD data items (https://en.wikipedia.org/wiki/OBD-II_PIDs ) for illustrating these concepts. Although SAE J/1979 defines several important ones, it is often the manufacturer specific ones that are most useful for connected vehicle and engineering laboratory exercises. The workshop will discuss how to access those PIDs and compare/contrast their use by two different vehicle manufacturers.
• Hands on connected and probe vehicle laboratory exercises integrated into Purdue University course curriculum.
