Embodiment Construction

[0045] now refer to figure 1 , which (schematically and partially) represents a motor vehicle 2 according to a second embodiment of the invention. The front of the vehicle emerges from the position of the headlights 4 and the steering wheel 6 and these elements are represented in top view so that the position of the vehicle is clearly discerned.

[0046] The vehicle comprises a front axle unit (also called a front axle unit) consisting of two front wheels with two front tires 8 and 10, typically (when the vehicle is moving in a straight line) in The transverse axis 12 (referred to as the front axle unit axis) is the center.

[0047] The horizontal longitudinal axis 14 of the vehicle 2 is the horizontal longitudinal center axis of the vehicle, which is conventionally arranged at the same height with respect to the ground as the axis 12 of the front axle unit. The vertical plane passing through this axis 14 is the vertical mid-longitudinal plane of the vehicle. This plane is ...

Abstract

This motor vehicle (2) comprises a rear bumper (22), defining an inner cavity open toward the front of the vehicle, and at least one microphone (24) comprising a sound capture member, intended to acquire a sound signal generated by at least one tire (8, 10, 16, 18) typically comprising at least one sound wear indicator. The sound capture member of the microphone (24) is fastened to a wall of the rear bumper (22), at a transverse level situated between the rear tires (16, 18), preferably in the inner cavity. The invention also relates to a rear bumper (22) thus equipped with a microphone (24).

Description

technical field [0001] The present invention relates to the technical field of detecting noise produced by a tire or tires, especially for motor vehicles (such as individual passenger vehicles or collective passenger vehicles) or utility vehicles (such as trucks or heavy vehicles, or tricycles, etc. Wait). Background technique [0002] Methods are known in the art for receiving in real time the sound signal emitted by a tire or tires while the vehicle is in motion, in particular for obtaining information about the condition of the road surface (eg how smooth it is) or the condition of tire wear Information. [0003] For example from patent application FR 0958586, it is also known to use at least one tire comprising one or more acoustic wear indicators, which thereby generate an acoustic fingerprint related to the wear condition of the tire and allow real-time detection of the wear condition of the tire. [0004] In particular, it is possible to use a microphone to receive ...
