Description
Technical Field
[0001] The present invention relates to a glass wiper device according to the preamble of the independent claim. Background Art
[0002] Some glass wiper devices for motor vehicles are known, which include a drive mechanism, a control mechanism for controlling the drive mechanism, and a wiper blade. Summary of the Invention
[0003] Advantages of the Invention
[0004] The glass wiper device according to the invention, having the features of the independent claim, has the advantage that an evaluation device for detecting environmental conditions is provided. Thereby, the glass wiper device can be optimally adjusted according to the existing environmental conditions in order to improve the wiping result.
[0005] Furthermore, by the measures recited in the dependent claims, advantageous developments and improvements of the features described in the independent claim are produced.
[0006] In a simple, low-cost and thus advantageous embodiment, the drive mechanism includes an electric motor, and the evaluation device evaluates the motor data of the electric motor.
[0007] Particularly advantageously, the current consumption and / or voltage curve and / or phase shift are set as the motor data. The environmental conditions can be particularly easily inferred from these data.
[0008] The particularly good detection of the environmental conditions is advantageously achieved by a sensor for detecting the environmental conditions.
[0009] In a simple, low-cost and thus advantageous embodiment, the sensor is configured as an acceleration sensor and / or as an environmental parameter sensor, in particular a temperature sensor, an air humidity sensor and / or a solar radiation sensor.
[0010] Here, it is particularly advantageous that the sensor is arranged in the wiper blade.
[0011] In a particularly advantageous embodiment, one of the environmental conditions is the current vehicle data, in particular the vehicle speed and / or vehicle acceleration.
[0012] Furthermore, it can be considered advantageous that a transmission unit for transmitting the parameters of the environmental conditions to a server unit is provided. Brief Description of the Drawings
[0013] An embodiment of the present invention is shown in the drawings and is explained in detail in the following description. Figure 1The glass wiper device according to the present invention is shown schematically. Detailed Description
[0014] Figure 1 The glass wiper device 10 according to the present invention and the glass 12 to be wiped are shown schematically.
[0015] The glass wiper device 10 according to the present invention includes a drive mechanism 14 connected to a control mechanism 16.
[0016] The drive mechanism 14 is connected to and drives a wiper blade 18 to wipe dirt and rainwater from the glass 12.
[0017] The drive mechanism 14 is controlled by the control mechanism 16.
[0018] In addition, an evaluation device 20 is provided, which is arranged in the control mechanism 16. The evaluation device 20 is used to detect the environmental conditions. For this purpose, the evaluation device 20 evaluates the motor data transmitted through a connection line 22 between the drive mechanism 14 and the control mechanism 16.
[0019] As the motor data, the current consumption of an electric motor is used here, and the electric motor is part of the drive mechanism 14. As an alternative, it is also possible to use a voltage curve, a phase shift or other motor characteristic parameters.
[0020] As an alternative or supplement, a sensor 24 is provided, which detects the environmental conditions. The sensor 24 is configured as an acceleration sensor, but it can also detect other environmental parameters, such as temperature, air humidity or solar radiation.
[0021] In an alternative embodiment, the sensor 24 can also be arranged in the wiper blade 18. It is also possible to provide another sensor in the control mechanism 16 in addition to the sensor 24 in the wiper blade 18.
[0022] The environmental conditions can be formed here by each environmental parameter that takes the environment into account. Here, for example, the weather represented by weather data can be considered, and other data, especially vehicle-related data, can also be considered. For example, the vehicle speed and / or vehicle acceleration can be detected. In this way, for example, the state, slow-moving traffic, stop-and-go or other traffic conditions can be detected. Similarly, for example, when using an acoustic sensor 24, an approaching ambulance or police car can be identified.
[0023] Based on the data representing all these environmental conditions, the drive mechanism 14 and thus the wiping operation of the wiper blade 18 can be optimally controlled.
[0024] The control mechanism 16 further includes a transmission unit 26 in this embodiment.
[0025] The transmission unit 26 transmits environmental conditions or environmental parameters to the server unit 28, which is arranged remotely from the glass wiper device 10 and communicates with the glass wiper device via a wireless connection 30, such as via a wireless mobile communication network.
[0026] Likewise, the server unit 28 can transmit information to the control mechanism 16 via the transmission unit 26, and the information is taken into account, for example, when controlling the drive mechanism 14.
[0027] The server mechanism 16 can also transmit this information to other vehicles and, for example, correspondingly control the glass wiper devices 10 of other vehicles, or evaluate and use the information in other ways.
[0028] As environmental conditions, information about the state and / or performance of the glass wiper device 10, such as its wear or anomalies, such as vibrations, can also be recognized and the drive mechanism 14 can be controlled accordingly.
[0029] If, for example, the evaluation device 20 determines via an acceleration sensor serving as the sensor 24 in the wiper blade 18 that the wiper blade 18 is stopped at the edge of the glass, this information can be used and the control mechanism 16 can control the movement of the wiper blade 18 caused by the drive mechanism 14 differently, such as reducing the swing angle, or when determining the vibration of the wiper blade 18, control the drive mechanism 14 in such a way that the vibration is prevented.
[0030] If the sensor 24 detects smoke or air pollution at a certain location, for example, the recirculation air valve of the vehicle can be switched to recirculation air operation. This can also be done via the transmission unit 26 and the server unit 28 in the case of a vehicle that is still remote and approaching the location.
