DRIVING ASSISTANCE FOR PARAPLEGIC PEOPLE - BRAKE ON HANDWHEEL COUPLED TO THE STEERING-BY-WIRE SYSTEM

摘要

This paper deals with a new solution for driving assistance, dedicated to the paraplegic people. This one consists to the development of a new braking device, coupled to the steering-by-wire system. This work represents a part of activities of a competitiveness pole in France, named MOVEO; it deals with the problematic of the Handicap and Mobility. The originality of this device is in the braking tool, which is the handwheel. The braking action is obtained by exerting a press force on the handwheel. For safety reasons, the movement of the handwheel will be released only when we actuate a braking start module using the inches. This device will allow the driver to brake and to accelerate while keeping the hands on the handwheel; this offers the advantage of an important gain in braking time and driving will become more flexible and more comfortable. A modeling of the dynamic's behavior of the driver bust was carried out, and a study on the operation mode and the applications of the x-by-wire technology in the automotive and its steering system.
