Lightweight, non-invasive collection of steering wheel angles and pedal positions

This paper presents a unit to measure steering wheel angles and pedal positions in cars where internal sensors cannot be installed or accessed. It provides the necessary information to build a version of the unit, to customize it for a given application and to understand its behavior. Circuit board layouts and CAD files for 3D printing are also provided online. The paper is mainly aimed at research institutions needing to collect this data in proving ground scenarios at a limited budged without requiring access to manufacturer's IP. The measurement uncertainty of steering wheel angles is shown to be in the order of 2 ° at a rate of about 5 Hz, but can be improved in individual applications.
