Abstract
This paper introduces a novel optimization tool designed to enhance sensor accuracy in automotive applications by determining the optimal dimensions and positioning of an axially magnetized cylindrical magnet used in magnetic linear sensors. Utilizing both the Finite Element Method and analytical equations, the study evaluates the impact of magnet properties on sensor performance, focusing on resolution and nonlinearity characteristics. Through comprehensive multivariate optimization, considering the constraints, optimal magnet configurations are identified, improving sensor accuracy and cost-effectiveness. The methodologies presented extend to various sensor types, offering a scalable approach to magnet design in e-mobility.
