Abstract
An overview of the field of contactless potentiometers in the automotive sector is presented. First, the main automotive systems that require the use of these devices are described. Then, the different sensors that can be employed to implement them are reviewed. Finally, a contactless potentiometer developed by the authors for automotive applications is described as a case study. It is based on a GMR Wheatstone bridge, is digitally configurable, and achieves maximum errors within +0.5° in an angular range of more than 100°.
