Development Strategy for Modular Design of Steering Column Based on ESSA Architecture

Steering column system main performance requirements are fully analyzed especially the structure performance, ergonomics performance etc. These dimensions are analyzed by deriving trends through simplifying algorithm, optimizing comfort range through statistical method, and puts forward concrete suggestions on quantitative target respectively. On this basis, torque fluctuation and ergonomics comfort issues in MPV under ESSA architecture are solved, and the modular development strategy of all four different types of vehicles under ESSA architecture is implemented, which ensures that the steering column system can not only meet the requirements of main performance, but also achieve the predetermined goal of maximum universality.
