As it turned out 2 1, which shows an example realization possibility for detecting a gear position information of the vehicle as well as an environment information, the step optionally includes the following:

• S21: detecting gear position information of the vehicle,
• - S22: Determine if the gear position information indicates the P position, proceed to step S23 when the gear position information indicates the P position, and inhibiting the execution of subsequent process steps when the gear position information indicates a position other than the P position and thus it is determined that the vehicle is in driving.
• - S23: capture environment information.

• - S12: Empfangen eines Türschloss-Steuersignals. Das Türschloss-Steuersignal kann ein Verriegelungssignal sowie ein Entriegelungssignal umfassen. Nach Empfangen eines Verriegelungssignals befindet sich das Türschloss in verriegeltem Zustand, während nach Empfangen eines Entriegelungssignals das Türschloss sich in entriegeltem Zustand befindet.
• - S13: Steuern des Betriebszustands des Scheibenwischers in Abhängigkeit der Gangstellungsinformation, der Umgebungsinformation und des Türschloss-Steuersignals.

In the above embodiment, an environment information is detected when the gear position information of the vehicle indicates the P position. A gear position information of the vehicle indicating a position other than the P position indicates that the vehicle is in running, in which case the control method for a windshield wiper is similar to the control method in the prior art, wherein a repetition is omitted here , With the above configuration, the environment information is detected only when the selector lever is in the P position, thereby effectively avoiding waste of resources and optimizing the flow of the control process.

• - S12: receiving a door lock control signal. The door lock control signal may include a lock signal and an unlock signal. After receiving a lock signal, the door lock is in the locked state, while after receiving an unlock signal, the door lock is in the unlocked state.
• - S13: controlling the operating state of the windscreen wiper depending on the gear position information, the environment information and the door lock control signal.

In this case, the operating state of the windscreen wiper may include a vertical state, a wiping state and an initial state. After determining the operating state of the windshield wiper in response to the gear position information, the environmental information and the door lock control signal, the windshield wiper is set in a corresponding operating state by controlling the windshield wiper electric motor.

With the above configuration, the vehicle is allowed to automatically control the operating state of the wiper based on the gear position information, the environment information, and the door lock control signal, thus effectively reducing the risk of freezing the wiper, satisfying the user's usage request, and improving the user experience of use ,

• - Umschaltung des Betriebszustands des Scheibenwischers in einen vertikalen Zustand beim Empfangen eines Verriegelungssignals, wenn die Gangstellungsinformation die P-Stellung angibt, die aktuelle Umgebungstemperatur gleich oder niedriger als eine erste vorbestimmte Temperatur beträgt und die aktuelle Wetterinformation auf aktuellen Regenfall oder Schneefall hinweist.

Optionally, the environmental information includes the current ambient temperature and the current weather information, the door lock control signal a lock signal and the operating state of the windscreen wiper a vertical state, wherein the control of the operating state of the windscreen wiper in dependence of the gear position information, the environment information and the door lock control signal comprises:

• - Switching the operating state of the windscreen wiper in a vertical state upon receiving a lock signal when the gear position information indicates the P position, the current ambient temperature is equal to or lower than a first predetermined temperature and the current weather information indicates current rainfall or snowfall.

• - S31: Feststellen, ob ein Verriegelungssignal empfangen wird, wenn die Gangstellungsinformation die P-Stellung angibt, die aktuelle Umgebungstemperatur gleich oder niedriger als eine erste vorbestimmte Temperatur beträgt und die aktuelle Wetterinformation auf aktuellen Regenfall oder Schneefall hinweist; Fortfahren mit S32, wenn ein Verriegelungssignal empfangen wird; Fortfahren mit S33, wenn kein Verriegelungssignal empfangen wird.

3 shows the control method for a windshield wiper according to another embodiment of the present invention in a flowchart. How out 3 can be seen, the procedure includes on the basis of 1 furthermore:

• S31: determining whether a lock signal is received when the gear position information indicates the P position, the current ambient temperature is equal to or lower than a first predetermined temperature, and the current weather information indicates current rainfall or snowfall; Proceed to S32 when a lock signal is received; Continue with S33 if no interlock signal is received.

In this case, the current weather information can be transmitted via an environment information Detecting device are detected. By way of example, the ambient information detection device comprises a temperature sensor, a sunlight rain sensor and a camera, etc. By way of example, the temperature sensor detects the current ambient temperature, if it is raining via the sunlight rain sensor, and images of the surroundings of the vehicle are recorded via the camera , so that it can be determined from such pictures, whether it is snowing now.

In this step, for example, first the gear position information can be determined, wherein subsequent method steps are not performed when the gear position information indicates a position other than the P position, which indicates moving vehicle. Since the windscreen wiper and the windscreen could freeze only at low temperature, in a gear position information indicating the P position, it is determined whether the current ambient temperature is equal to or lower than a first predetermined temperature, which first predetermined temperature, for example, to 5 ° C is set and can be set concretely depending on the environmental condition of the vehicle, with no limitation in the present invention. Upon determination that the current temperature is equal to or lower than the first predetermined temperature, it is then determined whether the current weather information is indicative of current rush or rainfall, with the windscreen wiper and windshield being subject to the risk of freezing, if so is. Therefore, upon receiving a lock signal indicative of user departure from the vehicle, the windshield wiper should be placed in a vertical position to avoid freezing of the windshield wiper on the windshield.

• - S32: Umschaltung des Betriebszustands des Scheibenwischers in einen vertikalen Zustand.

It is to be noted that the above exemplary order represents only an example realization possibility of this step, and by no means limits the present invention, wherein the execution order of the step is not limited thereto.

• - S32: Switching the operating state of the windscreen wiper to a vertical state.

In the above embodiment, when the selector lever is in the P position, that is, when parking the vehicle by detecting the current ambient temperature and the current weather information, it is determined whether the vehicle should bring the wiper into a vertical position. At the same time, upon receiving a lock signal, the operating state of the windscreen wiper is switched to a vertical state while no operation of the windscreen wiper occurs when no lock signal is received. With the above configuration, the intention of the user can be automatically determined so that only upon receiving a lock signal, the wiper is brought into a vertical position and thus the control method is better adapted to the user's use requirement, thereby impairing the view of the user forward through standing in a vertical position windshield wiper is avoided when temporarily stopping the vehicle, which in addition to preventing frozen windshield wiper on the windscreen driving safety for users is ensured.

• - Umschaltung des Betriebszustands des Scheibenwischers in einen abwischenden Zustand vor Empfangen eines Verriegelungssignals, wenn die Gangstellungsinformation die P-Stellung angibt, die aktuelle Umgebungstemperatur gleich oder niedriger als eine erste vorbestimmte Temperatur beträgt und die aktuelle Wetterinformation auf aktuellen Regenfall oder Schneefall hinweist.

Optionally, the operating condition of the windscreen wiper further comprises a wiping condition,
wherein the control of the operating state of the windshield wiper according to the gear position information, the environment information and the door lock control signal further comprises:

• - Switching the operating state of the windscreen wiper in a wiping state before receiving a lock signal when the gear position information indicates the P position, the current ambient temperature is equal to or lower than a first predetermined temperature and the current weather information indicates current rainfall or snowfall.

• - S33: Umschaltung des Betriebszustands des Scheibenwischers in einen abwischenden Zustand.

How out 3 it can be seen, for example, in S31 With S33 continued if no interlock signal is received.

• - S33: switching the operating state of the windscreen wiper to a wiping state.

In the above example, when the gear position information of the vehicle indicates the P position and no interlock signal is received, it can be considered that the vehicle is in temporary halt. In this case, the operating state of the windscreen wiper is switched to a wiping state when the windshield wiper does not start to operate while the current operating state of the windscreen wiper is maintained when the windshield wiper is already in wiping condition. Upon receiving a lock signal indicative of a possible long-term stop of the vehicle or leaving the user of the vehicle, the operating state of the windscreen wiper is then switched to a vertical state to prevent the windscreen wiper from freezing on the windscreen.

In the above embodiment, the operating state of the windscreen wiper is switched to a wiping state when the wiper is exposed to the risk of freezing the wiper and no interlock signal is received. With the above configuration, the risk of freezing the windshield wiper can be effectively reduced on the one hand when the vehicle is parked. On the other hand, when the vehicle is stopped for a short time, the operating state of the windscreen wiper is switched to a wiping state, thereby effectively preventing forward visibility of the user from snowfall or rainfall, and providing a clear view to users upon starting the vehicle after a short stop, which is too secure Driving safety for users contributes.

• - S42: Umschaltung des Betriebszustands des Scheibenwischers in einen vertikalen Zustand, wenn die Wettervoraussageninformation auf zukünftigen Schneefall oder Regenfall innerhalb eines ersten vorbestimmten Zeitraums hindeutet.

In this step, for example, first the gear position information can be determined, wherein subsequent method steps are not performed when the gear position information indicates a position other than the P position, which indicates moving vehicle. Since the windscreen wiper and the windscreen could freeze only at low temperature, in a gear position information indicating the P position, it is determined whether the current ambient temperature is equal to or lower than a first predetermined temperature, which first predetermined temperature, for example, to 5 ° C is set and can be set concretely depending on the environmental condition of the vehicle, with no limitation in the present invention. Upon determination that the current temperature is equal to or lower than the first predetermined temperature, it is then determined whether the current weather information is indicative of current rush or rainfall, and then it is determined whether a lock signal is received, that is, if the user leave the vehicle if the current weather information indicates no recent snowfall or rainfall.

• - S42: switching the operating state of the windscreen wiper in a vertical state when the weather forecast information indicates future snowfall or rainfall within a first predetermined period.

Here, the surrounding information acquiring means may further include weather forecast information acquiring means having internet access for obtaining weather forecast information based on the weather forecast, wherein the weather forecast information may be acquired on the vehicle via, for example, a T-box network. The first predetermined period of time may vary depending on the characteristics of the environment of the vehicle, e.g. the ambient temperature and the climate are set. For example, the first predetermined time period may be set at 2 hours for stable weather change regions and at 1 hour for drastic weather change regions.

In the case of current weather information, which does not indicate any current snowfall or rainfall, it is assumed that the windscreen wiper is currently not subject to any risk of freezing. Upon receiving a lock signal, it is assumed that the user could now leave the vehicle. Although the current weather information does not indicate any recent snowfall or rainfall, due to the low current ambient temperature, the weather forecast information is to be collected to determine if snowfall or rainfall is to be expected within a future time period, ie if the windshield wiper is within a future period of time Freezing on the windscreen is subject. If the weather forecast information on future snowfall or rainfall within the indicates the first predetermined period of time, the operating state of the windscreen wiper is switched to a vertical state.

In the above embodiment, by detecting weather forecast information, it is determined whether snowfall or rainfall is expected within a future period, with the operating state of the windscreen wiper being switched to a vertical state, if this is the case. With the above configuration, a comprehensive prediction of possible scenarios in which the windshield wiper could freeze is enabled, and the operating state of the windshield wiper is switched to a vertical state when the windshield wiper is at risk of freezing, thus effectively freezing the windshield wiper at the windshield prevent and improve the usage experience for users.

5 shows the control method for a windshield wiper according to another embodiment of the present invention in a flowchart. How out 5 can be seen, the procedure includes on the basis of 2 For example:

• S51: determining whether the current ambient temperature is equal to or lower than the first predetermined temperature, proceeding to S52 if so, and proceeding to S56 if the current ambient temperature is higher than the first predetermined temperature.

• - S52: Feststellen, ob die aktuelle Wetterinformation auf aktuellen Schneefall oder Regenfall hinweist, Ausführen des Verfahrensschritte nach 3, wenn dies der Fall ist, und Fortfahren mit S53, wenn die aktuelle Wetterinformation auf keinen aktuellen Schneefall oder Regenfall hinweist.

The first predetermined temperature may be set to, for example, 5 ° C.

In this case, it is assumed that the windshield wiper could currently freeze in a current weather information, which indicates current snowfall or rainfall. Now, the windscreen wiper according to the method steps after 3 to be controlled. If the current weather information does not indicate any current snowfall or rainfall, ie no risk of freezing the windscreen wiper, then a determination is made on the basis of other conditions.

• - S53: Determine if a lock signal is received, proceed to S54 if so, and wait for a lock signal if no lock signal is received.
• S54: determining whether the weather forecast information indicates future snowfall or rainfall within a first predetermined time period, proceeding to S55 if this is not the case, and switching the operating state of the windscreen wiper to a vertical state if this is the case.

• - S55: Feststellen, ob ein Entriegelungssignal innerhalb des ersten vorbestimmten Zeitraums empfangen wird, Fortfahren mit S21, wenn dies der Fall ist, und Fortfahren mit S23, wenn innerhalb des ersten vorbestimmten Zeitraums kein Entriegelungssignal empfangen wird.

In this case, after receiving a lock information, a determination is made as to whether a snowfall or rainfall is to be expected within the first predetermined period, ie a determination based on the weather forecast information after leaving the user of the vehicle, so that the visibility of the user from the front through vertical position wipers can be avoided when briefly stopping the vehicle. By thus controlling the windshield wiper in consideration of the user's intention, that is, by not putting the windscreen wiper in a vertical position before receiving a lock signal, the control method is better adapted to the usage habit of the user, thus improving the usage experience for users.

• S55: determining whether an unlock signal is received within the first predetermined time period, proceeding with S21 if so, and proceeding to S23 if no unlock signal is received within the first predetermined time period.

• - S56: Feststellen, ob sich das Türschloss aktuell in verriegeltem Zustand befindet, Fortfahren mit S57, wenn dies der Fall ist, und Fortfahren mit S21, wenn dies nicht der Fall ist.
• - S57: Feststellen, ob die aktuelle Umgebungstemperatur höher als eine zweite vorbestimmte Temperatur liegt, Fortfahren mit S59, wenn dies der Fall ist, und Fortfahren mit S58, wenn dies nicht der Fall ist.

For example, the first predetermined period may be set to 2 hours. If determined by weather forecast information that snowfall or rainfall is not expected within 2 hours, it is assumed that the windscreen wiper will not be subject to any risk of freezing within 2 hours. Thereafter, a determination is made as to whether an unlock signal is received within 2 hours, upon receipt of an unlock signal assuming that the user is likely to restart the vehicle, in which case it returns to step detecting gear position information of the vehicle to determine whether the user has started the vehicle while returning to step detecting environment information to determine whether the environment information has changed when no unlock signal is received, indicating that the vehicle is still in a parked state.

• - S56: Check if the door lock is currently locked, continue with S57 if so, and continue with S21 if this is not the case.
• - S57: Determine if the current ambient temperature is higher than a second predetermined temperature, proceed with S59 if so, and continue with S58 if this is not the case.

• - S58: Feststellen, ob ein Entriegelungssignal innerhalb eines zweiten vorbestimmten Zeitraums empfangen wird, Fortfahren mit S21, wenn dies der Fall ist, und Fortfahren mit S23, wenn innerhalb des zweiten vorbestimmten Zeitraums kein Entriegelungssignal empfangen wird.
• - S59: Feststellen, ob ein Entriegelungssignal innerhalb eines dritten vorbestimmten Zeitraums empfangen wird, Fortfahren mit S21, wenn dies der Fall ist, und Fortfahren mit S23, wenn innerhalb des dritten vorbestimmten Zeitraums kein Entriegelungssignal empfangen wird.

In this case, the first predetermined temperature is lower than the second predetermined temperature. For example, the first predetermined temperature may be set to 5 ° C and the second predetermined temperature may be set to 10 ° C.

• - S58: Determine if an unlock signal is received within a second predetermined time period, proceed with S21 if so, and continue with S23 if no unlock signal is received within the second predetermined time period.
• - S59: determining whether an unlock signal is received within a third predetermined period, proceeding with S21 if so, and continue with S23 if no unlock signal is received within the third predetermined time period.

At this time, the second predetermined period is shorter than the third predetermined period. Since the risk of freezing the windshield wiper decreases with the increase of the ambient temperature, the period for monitoring the reception of an unlocking signal can be set to a longer value, so that a lower risk of freezing at a higher ambient temperature corresponds. For example, at a first predetermined temperature of 5 ° C and a second predetermined temperature of 10 ° C, the second predetermined period may be set to 2 hours and the third predetermined period may be set to 4 hours.

For example, at a current ambient temperature of 6 ° C, which is higher than the first predetermined temperature of 5 ° C and lower than the second predetermined temperature of 10 ° C, a determination is made whether within 2 Hours an unlock signal is received. Upon receiving the unlock signal indicative of likely starting of the vehicle by the user, a step of detecting a gear position information of the vehicle is returned to see if the user has started the vehicle while returning to the step of detecting an environment information to determine whether the environment information has changed when no unlock signal is received, indicating that the vehicle is still parked. For example, at a current ambient temperature of 12 ° C, which is higher than 10 ° C, a determination is made whether an unlocking signal is received within 4 hours, the subsequent determination steps can be taken from the above description and is omitted here a repetition ,

• - Ansteuern einer Zurückstellung des Scheibenwischers in den Anfangszustand, wenn ein Entriegelungssignal empfangen wird und die Gangstellungsinformation eine andere Stellung als die P-Stellung angibt.

Optionally, controlling the operating state of the windshield wiper according to the gear position information, the environment information and the door lock control signal after switching the operating state of the windscreen wiper to a vertical state further comprises:

• - Actuating a deferral of the windscreen wiper in the initial state when an unlock signal is received and the gear position information indicates a position other than the P position.

For example, it is assumed that the user will now start the vehicle when, after switching the operating state of the windscreen wiper to the vertical state, the unlock signal is received and the gear position information indicates a position other than the P position. Since the windshield wiper is now in a vertical position and could obstruct the user's vision during vehicle driving, the operating state of the windscreen wiper is to be switched to the initial state, at which initial state the windscreen wiper is in an off position.

In the above embodiment, upon receiving the unlock signal from the gear position information of the vehicle, it is determined whether the select lever is in the P position, and the operating state of the windshield wiper is changed to the initial state when the current gear position information of the vehicle is in a position other than the P position. Indicates position. Thus, in favor of the driving safety for users, an automatic reset of the windscreen wiper in the initial state can take place if, after moving the windscreen wiper into a vertical position, the user wishes to start the vehicle.

In addition, in the present invention, the vehicle is additionally provided with a switch for setting the windscreen wiper in a vertical position, which includes an automatic switching position for placing the windscreen wiper in a vertical position. When the switch for setting the wiper to the vertical position in the automatic shift position and the wiper automatic switch is in an automatic position, the above-described control method for a windshield wiper is executed.

Optionally, the switch for setting the windshield wiper in vertical position may further comprise a vertical shift position and a return shift position. Upon manual setting of the switch in the vertical position by the user, the operating state of the windscreen wiper is switched to a vertical state, while manually set the switch in the reset switching position by the user, the operating state of the windscreen wiper is reset to the initial state. Thus, via the switch for setting the windscreen wiper in a vertical position, the user can manually set or reset the windscreen wiper to meet the user's use requirement. It should be noted that when controlling the windscreen wiper, the user takes precedence over the control unit.
