Problems solved by technology

[0005] However, these known systems do not know exactly how many fingers are actively touching the steering wheel; nor do these known systems detect whether the driver's hands are not touching the steering wheel (not holding the steering wheel)
A system that detects a force couple applied to the steering wheel cannot distinguish whether the force couple is applied by a hand or another part of the body, such as a knee, or whether the hand is only resting on the steering wheel without applying force

Embodiment Construction

[0037] figure 1 A general schematic view of a steering wheel 2 of a motor vehicle is shown. The figure shows the steering wheel of the vehicle, which is connected to the steering system of the vehicle through the steering column with axis X. The steering wheel 2 includes a detection device 3 whose main purpose is to detect the quality of the driver's grip on the steering wheel, but it can also detect that the driver is not gripping the steering wheel.

[0038] The steering wheel 2 comprises a middle part 61, called a hub, and also a rim 25, which in the example shown is connected to the hub by three branches, but the number of branches could also be four or even two, Or the steering wheel may be a single branch type steering wheel.

[0039] The detection device 3 comprises a plurality of sensors 7 arranged on the rim 25 of the steering wheel 2 . exist Figure 2A , it can be seen that hand 4 (left hand 4G, right hand 4D) grips steering wheel 2 in a grip position called "9h1...

Abstract

A system for a motor vehicle comprises a steering wheel (2) connected to the steering system of the vehicle, the steering wheel comprising a plurality of optical sensors (7) arranged on the rim (25) of the steering wheel and configured to detect the presence of at least one finger (5) of at least one hand of the driver near or in contact with the rim of the steering wheel, by means of which the system is able to determine the number of fingers near or in contact with the rim of the steering wheel and their positions with respect to the rim. The invention covers a method associated with the device.

Description

technical field [0001] The present invention relates to a system and method allowing detection of the presence of one or more fingers and / or hand(s) near the steering wheel of a motor vehicle. [0002] More precisely, it relates to the extent to which the driver of the vehicle is holding the steering wheel in an active and forceful manner, and this information is transmitted to driver alert monitoring systems and / or driver assistance systems, or even automated driving systems. Background technique [0003] It is known to measure the force couple exerted by the driver's hands on the steering wheel, for example in electrically assisted steering systems. [0004] It is also known from document US 2014 054 880 A1 to arrange a plurality of sensors inside the steering wheel rim of a vehicle in order to detect the strong pressure exerted by the driver's fingers and hands, for example in order to control an airbag protection system. [0005] However, these known systems cannot clea...
