Title (EN) STEERING WHEEL HANDS ON/OFF DETECTION SYSTEM
(FR) SYSTÈME DE DÉTECTION DE MAINS SUR UN VOLANT DE DIRECTION
Abstract:
(EN) It is disclosed a system (1) and a method for detecting the presence or the absence of a hand on a steering wheel (9), the steering wheel being provided with one or more conductive wires (2, 2a, 2b, 3), said system (1) comprising a detection device (5) comprising an input circuit (6) for providing an input signal (11) to at least one conductive wire (2, 2a) of said one or more conductive wires (2, 2a, 2b, 3), said input signal (11) being an electrical signal having a frequency comprised in the RF range, and an output circuit (7) configured for sensing the impedance of said at least one conductive wire (2) or for sensing the inductive coupling between said at least one conductive wire (2a) and at least one second conductive wire (2b) in response to said input signal. The detection device (5) is configured for detecting a change in value of the impedance of said at least one conductive wire (2, 2b) or for detecting a change in value of said inductive coupling between said at least one conductive wire (2a) and said at least one second conductive wire (2b), that is indicative of the presence or the absence of a hand on said steering wheel (9).
(FR) L'invention concerne un système (1) et un procédé qui permettent de détecter la présence ou l'absence d'une main sur un volant de direction (9), le volant de direction étant pourvu d'un ou de plusieurs fils conducteurs (2, 2a, 2b, 3), ledit système (1) comprenant un dispositif de détection (5) comprenant un circuit d'entrée (6) afin de fournir un signal d'entrée (11) à au moins un fil conducteur (2, 2a) dudit ou desdits fils conducteurs (2, 2a, 2b, 3), ledit signal d'entrée (11) étant un signal électrique ayant une fréquence comprise dans la plage RF, et un circuit de sortie (7) configuré de sorte à détecter l'impédance dudit ou desdits fils conducteurs (2) ou pour détecter le couplage inductif entre ledit ou lesdits fils conducteurs (2a) et au moins un second fil conducteur (2b) en réponse audit signal d'entrée. Le dispositif de détection (5) est configuré de sorte à détecter un changement de valeur de l'impédance dudit ou desdits fils conducteurs (2, 2b) ou pour détecter un changement de valeur dudit couplage inductif entre ledit ou lesdits fils conducteurs (2a) et ledit ou lesdits seconds fils conducteurs (2b), qui indique la présence ou l'absence d'une main sur ledit volant de direction (9).
