The invention relates to a method for determining the wiping use of a wiper blade (14) pertaining to a wiper system (10) used to wipe a window pane (12) of a motor vehicle, with a view to replacing said wiper blade once it exceeds a determined wear threshold, the wiper blade carrier (16) being movable between a position of use, called a service position, and a maintenance position, said method being characterised in that it successively comprises: a step a) of acquiring at least one data element representing the presence of the wiper blade (14) in the maintenance position; a step b) of determining the replacement of the wiper blade with a new wiper blade; and a step (c) of estimating the wiping use of the new wiper blade.

A wiper blade rubber strip and a method for manufacturing the same are disclosed. The wiper blade rubber strip includes a rubber strip body made of a first rubber material and a blade portion made of a second rubber material. The blade portion is integrally formed with the rubber strip body by co-extrusion. The rubber strip body and the blade portion are made of different materials to meet their respective performance requirements of the rubber strip body and the blade portion.

The invention relates to a wiping device (1) for a motor vehicle window (30), comprising a windscreen wiper frame (10) and a piezoelectric film (2), said piezoelectric film (2) being mounted on the windscreen wiper frame (10) such as to produce an electric current. The invention also relates to a warning method and a spray control method for such a wiping device (1).

Computing systems for vehicle diagnostics are provided. In accordance with some aspects, a computing system may receive, from a vehicle (e.g., from a computing device installed in and/or at the vehicle), a diagnostic code generated by an on-board diagnostic (OBD) system of the vehicle. The computing system may determine an issue with the vehicle based on the diagnostic code and may determine, based on the issue, a remedial action for addressing the issue and a timeframe for performing the remedial action. The computing system may store data identifying the issue, the remedial action, and the timeframe in a record associated with the vehicle.

Method and apparatus are disclosed for accelerometer-based windshield wiper monitoring. A vehicle includes an accelerometer affixed to a vehicle window, a windshield wiper to actuate across the vehicle window, and a processor. The processor is configured to determine an acoustic profile corresponding to the windshield wiper based on structure-borne audio data received from the accelerometer, determine whether a bandlimited decibel level of the acoustic profile exceeds a threshold, and responsively provide an alert via a vehicle display.

A system includes a computer including a processor and a memory, the memory storing instructions executable by the processor to actuate a windshield wiper on a vehicle, collect amplitude data and frequency data from a sound of the windshield wiper, and, upon determining that the amplitude data meets a first predetermined threshold and the frequency data meets a second predetermined threshold, actuate a vehicle component to move the vehicle to a specified location.

A wiper blade connector for connecting a wiper blade to a wiper arm, has: an adaptor secured to an end of the wiper arm; a base secured to the wiper blade; a locking member operatively mounted to one of the adaptor and the base and movable relative to the one of the adaptor and the base between a locked position and an unlocked position, the adaptor secured to the base via the locking member in the locked position, the adaptor detachable from the base in the unlocked position; a user-engageable member operatively connected to the locking member, the user-engageable member movable to move the locking member from the locked position to the unlocked position to detach the adaptor from the base.

The present invention relates to a composition (1) which makes it possible to show the wiping defects (3) of a wiper blade (5), in particular for a motor vehicle (7), in order to determine the state of wear of the wiper blade (5), the said composition (1) which makes it possible to show the wiping defects (3) being intended to be deposited as a layer on a windscreen (9) of the said motor vehicle (7), characterized in that the composition (1) which makes it possible to show the wiping defects (3) comprises a tracer compound (11) which makes it possible to bring to light the wiping defects (3) of the wiper blade (5) and exhibits: a density of between 0.75 and 1.25 at 20 C., and a viscosity of between 0.001 and 1.5 Pa.Math.s at 20 C.

The present invention relates to a method for estimating a state of wear of a wiper strip of a wiper blade for a wiper system of a motor vehicle. The method is implemented by a mobile command terminal. The method includes activating the mobile communication terminal by communicating information to it via a human-machine interface, determining a geographical position of the motor vehicle, evaluating the state of wear of the wiper strip on the basis of the activation step and the geographical position, and generating an alert when the state of wear reaches a threshold level.
