Active Engine Management Sensors for Power Train Efficiency

Abstract

“Clean performance”- the challenge with regard to improved driving performance and at the same time lower fuel consumption goes on. In addition to this lower exhaust limits are set by law. This bears the need for even more advanced engine management systems in future. These challenging targets result in higher requirements to engine management sensors with respect to accuracy, electromagnetic compatibility (EMC) and optimum operation with an increasing variety of applications. The development of a brand-new active engine management sensor generation based on giant magnetoresistance (GMR) has just been finished. The unique features of this new technology are high accuracy (repeatability), fast start-up calibration and high EMC robustness.
