Download in .pdf format Download in .docx format

Proposal to allow for the use of the maximum operable steering wheel angle of a steering system’s design in cases where the normalized angle as calculated under the regulation cannot meet the fixed values of the regulation (i.e., between 270 and 300 degrees). The intention is to enable approval of eventual systems (e.g., steer-by-wire) that may use low steering gear ratios.
