Choosing the method for determining angular motions of motor vehicle electromechanical subassemblies

Abstract

The most common methods and devices for determining the rotational angle of electromechanical subassemblies (RAEMSA) of motor vehicles were analyzed. The analysis showed that the incremental method proves to be the most favorable for automobiles involving a synchronization disk and a digital Hall sensor for mechanisms that make a full rotational movement, AMR sensors for mechanisms operating in a limited sector of the rotational angle. An algorithm for processing the sensor signals to expand the measuring range for the angle of the operating mechanism position has been developed. This algorithm allows doubling the measuring range for the angle of the working mechanism position.
