Description

Title of the invention: Vehicle windshield wiper device FIELD OF THE INVENTION

[0001] The present invention relates to a vehicle windscreen wiper device comprising a drive unit controlled by a control installation and a windscreen wiper blade. STATE OF THE ART

[0002] Such vehicle windshield wiper devices are already known.

[0003] DISCLOSURE AND ADVANTAGES OF THE INVENTION

[0004] The present invention relates to a windscreen wiper device for a motor vehicle comprising a drive installation, a control installation for controlling the drive installation and a windscreen wiper blade, this device being characterized in that it comprises an operating means for capturing the state of the environment.

[0005] The windshield wiper device according to the invention has the advantage of having an operating means for capturing the state of the environment. This makes it possible to adjust the wiping device to improve the wiping result optimally according to the corresponding state of the environment.

[0006] According to a simple, economical and advantageous development, the drive installation comprises an electric motor and the operating unit uses the data from the electric motor.

[0007] Particularly advantageously, the motor data are the current intake and / or the voltage curve and / or the phase shift. From such data, conclusions can be drawn regarding the state of the environment captured by a sensor.

[0008] According to a simple and economical, and therefore advantageous, embodiment, the sensor is an acceleration sensor and / or an environmental parameter sensor, in particular a temperature, air humidity or solar radiation sensor. This results in a particular advantage if the sensor is integrated into the windscreen wiper blade.

[0009] According to a particularly advantageous development, the environmental state is that of the current vehicle data, in particular, the vehicle speed and / or its acceleration.

[0010] It is further advantageous to provide a unit for transmitting the parameters of the environment state to a server.

[0011] BRIEF DESCRIPTION OF THE DRAWING

[0012] The present invention will be described below in more detail with the aid of the attached drawing in which:

[0013] [Fig-1] Schematic view of an embodiment of the invention showing a windshield wiper device applied to the window.

[0014] DESCRIPTION OF THE EMBODIMENT OF THE INVENTION

[0015] [Fig.l] shows a windscreen wiper device 10 according to the invention as well as a schematic representation of the window 12 to be wiped.

[0016] The windshield wiper device 10 according to the invention comprises a drive installation 14 connected to a control installation 16. The drive installation 14 is connected to the windshield wiper blade 18, driving the latter to wipe dirt and rain from the window 12.

[0017] The drive installation 14 is controlled by the control installation 16.

[0018] An operating means 20 is also provided in the control installation. 16. The evaluation means 20 serves to record environmental situations. For this purpose, the evaluation means 20 uses the engine data transmitted via a connecting line 22 connecting the drive system 14 and the control system 16.

[0019] The motor data here is the electrical power consumed by the electric motor which is part of the drive installation 14. Alternatively, the voltage curve, the phase shift or any other parameter of the motor can also be used.

[0020] Alternatively or additionally, a sensor 24 is provided which captures the state of the environment. The sensor 24 is an acceleration sensor, but it can also capture other parameters of the environment, for example, temperature, air humidity or solar radiation.

[0021] According to an alternative embodiment, the sensor 24 is integrated in the windshield wiper blade 18. It is also possible to have another sensor in the control installation 16 next to the sensor 24 in the windshield wiper 18.

[0022] The state of the environment is represented by any parameter of the environment. This includes, for example, the weather conditions represented by the weather data and also other data, in particular data relating to the vehicle. For example, the vehicle speed and / or its acceleration can be recorded. In this way, for example, traffic jams, heavy traffic, start / stop operation or other traffic conditions can be recorded. In the same way, for example, with an acoustic sensor 24, the arrival of an emergency vehicle or a police vehicle can be detected.

[0023] With the data representing the environmental states, the drive system 14 and the operation of the wiper blade 18 will be optimally controlled.

[0024] The control installation 16 of the present embodiment also comprises a transmission unit 26.

[0025] The transmission unit 26 transmits the state of the environment or the parameters of the environment to a server 28 remote from the windshield wiper device 10 and with which it communicates via a wireless link 30, for example, via a mobile telephone network.

[0026] The server 28 can also transmit information via the transmission unit 26 to the control system 16; this information is, for example, taken into account for controlling the drive system 14.

[0027] The server 16 can also transmit this information to other vehicles and, for example, whose windshield wiper device 10 is controlled correspondingly or the information which will be used in another way.

[0028] With the information concerning the state and / or behavior of the windshield wiper device 10, it is possible, for example, to detect wear or defects such as clicking as an environmental condition and to control the drive system 14 accordingly.

[0029] For example, the operating means 20 detects, by the acceleration sensor which is the sensor 24 integrated in the windshield wiper 18 that the windshield wiper 18 comes to abut against the edge of the window, this information can be used to control the control installation 16 for the movement of the windshield wiper blade 18 on the drive installation 14 in a different way, for example, to reduce the angle of the pendulum movement or by detecting the clicking noise of the windshield wiper blade 18, to control the drive installation 14 to avoid this noise.

[0030] If the sensor 24 detects, for example, smoke or air pollution at a certain position, it can switch the air intake flap of the vehicle to the circulation mode. The transmission unit 26 and the server 28 can also have this information in vehicles that are still far away and that are approaching this position.
