Problems solved by technology

One solution is to spray a lot of liquid onto the optical surface of the detection module in question and then let the optical surface dry, but this solution can be expensive in terms of cleaning fluid or water, especially for autonomous vehicles Thus, in an autonomous vehicle, many detection modules are employed around the vehicle
[0004] Also, since they are located outside the vehicle, these detection modules may be damaged in the event of a collision
Even at low speeds, such collisions can cause irreversible damage to these detection modules

Embodiment Construction

[0038] In the remainder of the description, the terms "longitudinal", "transverse" and "vertical" refer to the orientation when the driver assistance system 100 of the present invention is integrated into a vehicle. Thus, the term "longitudinal" corresponds to the direction parallel to the longitudinal axis L of the trihedron L, V, T shown in the figure, and the term "transverse" corresponds to the direction parallel to the transverse axis T of the trihedron, which is perpendicular to With regard to the longitudinal axis L, the term "perpendicular" corresponds to a direction parallel to the vertical axis V of the trihedron, which is perpendicular to the longitudinal axis L and the transverse axis T. Cross section refers to sections taken in longitudinal and transverse planes, ie planes containing the longitudinal axis L and transverse axis T of the L, V, T trihedron shown.

Abstract

The invention relates to a motor vehicle driver assistance system (100) comprising at least one detection module (101) and one cleaning system (120), the detection module comprising at least one driver assistance sensor (110, 130) and at least one protective glass pane (140) closing the detection module (101) and protecting the at least one driver assistance sensor (110, 130), the cleaning device (120) being configured to clean the protective glass pane (140), and the cleaning device (120) comprising at least one wiper blade (121) in contact with the protective glass pane (140) and movable along a main direction (D) of rectilinear movement.

Description

technical field [0001] The invention relates to a driver assistance system of a motor vehicle, and more particularly to a cleaning device associated with a detection module of such a driver assistance system. Background technique [0002] Vehicles, in particular motor vehicles, increasingly comprise automated systems, in particular driver assistance systems. Such a driver assistance system comprises in particular one or more modules for detecting the surroundings of the vehicle and external parameters of the vehicle, and also comprises at least one control unit configured to interpret the information thus collected and Make the decisions that need to be made based on that information. [0003] It will therefore be understood that it is particularly important to check that these detection modules are functioning properly throughout the life of the vehicle. In particular, these detection modules are usually arranged on the outside of the vehicle, for example carried on the b...
