Problems solved by technology

These depth and height adjustments are generally controlled manually and the adjustment position cannot be known electronically
As a result, camera-based devices capable of detecting finger movements can often only give a vague interpretation of the driver's expressed intentions

Embodiment Construction

[0037] figure 1 The central area of ​​the driver's seat is shown from the driver's point of view (in the case of straight driving). In the cockpit facing the driver, there is an instrument cluster 9 , a ("driving") steering wheel 8 for maneuvering the vehicle, which in this case includes (one or more) (LCD or pixelated) digital Display area 19 , steering wheel 8 is mounted for rotation about axis X (movement denoted variable θ) and includes rim 82 . The instrument cluster 9 forms a display device, which may also comprise various indicator lights, signal lamps, dials, as known per se.

[0038] In addition, there are other display devices and other control devices in the driver's general field of vision. The driver can be guided to interact with various systems on board the vehicle, such as, for example, the car radio, the multimedia system, the air conditioning system, the distance control system, and the like.

[0039] In the application shown here, the steering wheel 8 and...

Abstract

System for detecting the position of a steering wheel (8) of an automotive vehicle, the system comprising a matrix optical detection device with three-dimensional detection (1), known in English as a"Time-of-Flight Camera", with an infrared light source (11) and a matrix optical sensor (12), optical tagging elements (2) arranged on the rim (82) of the steering wheel, on the opposite side to the driver, the matrix optical detection device being arranged in an instrument console (9) of the vehicle, and being configured to detect the optical tagging elements on the steering wheel, and deduce therefrom the position of adjustment of the steering wheel at least in terms of depth.

Description

technical field [0001] The present invention relates to systems and methods for optically detecting the position of a steering wheel in a motor vehicle. Background technique [0002] It is known to arrange control buttons in the branches of the steering wheel connecting the central part to the rim of the steering wheel, eg in order to control communication and / or audio functions or even speed limiting / regulating functions. [0003] However, in the context of increasingly elaborate human-machine interfaces, this solution is not flexible, since buttons are often dedicated. Touch areas are also provided on one or more spokes of the steering wheel as an alternative to control buttons. [0004] Driving safety dictates keeping hands on or close to the steering wheel. [0005] It has also been proposed to use a camera to detect certain gestures made by the driver's fingers when the driver's hands are around the steering wheel. However, the accuracy of this detection needs to be ...
