Definitions
- the invention relates to a method for determining the state of a wiper rubber of a wiper blade for a vehicle.
- Comparative wear element via an optical check of the surface structure of the wiper strip, via the wear of the wiper strip, via a comparison of the light beam reflection before and after the wiping process on the window, via a counter which records the number of wiping movements and a measuring device which measures the energy consumption for driving the wiper strip monitor.
- the monitoring of such influencing variables has either proven to be very complex, in particular through the use of additional components or sensors, or very inaccurate.
- the invention is therefore based on the object of proposing a method for determining the condition of a wiper blade of a wiper blade for a vehicle, in which the condition of the wiper blade can be exactly determined without using additional components or sensors.
- This object is achieved according to the invention in that the number of post-wiping cycles during interval wiping is monitored as an influencing variable for wear of the squeegee and is compared with stored comparison variables and that a message is issued when a predetermined constellation of monitored influencing variables and comparison variables is reached.
- a wiping cycle is understood to mean a back and forth movement of the windshield wiper.
- the invention is based on the principle that, depending on the condition of the squeegee, a corresponding number of wiping cycles are required when wiping the interval. With a certain degree of precipitation, especially with drizzle, a new, perfect squeegee wipes the window of the vehicle without a wiping cycle. For an older, worn squeegee, with the same level of rainfall, interval wiping cycles are required. The worse the condition of the squeegee, the more wiping cycles are required to remove the precipitate on the window of the vehicle.
- the message is sent, in particular to the vehicle driver, so that the driver receives an indication that a wiper blade change is necessary.
- the installation time of the wiper rubber and / or the number of total wiping cycles and / or the rubber friction on the pane, in particular via the wiper motor characteristic, and / or the temperature, is a further influencing variable. in particular temperature on the vehicle window is monitored.
- the other influencing variables mentioned can be monitored and provided with little effort, in particular in combination with the number of wiping cycles when wiping intervals, reliable information about the condition of the wiper rubber.
- the number of wiping cycles during interval wiping is monitored by means of a rain sensor monitoring the vehicle window.
- a rain sensor monitoring the vehicle window.
- Such rain sensors which monitor the degree of precipitation on the windshield of the vehicle and consequently determine the wiping speed of the wiper blades, are used as standard in modern vehicles. This means that no additional component or sensor is required to count the number of wiping cycles when wiping intervals. To determine the number of wiping cycles when wiping the intervals by means of the rain sensor, only one counter in the rain sensor control is required.
- the rain sensor monitors the degree of precipitation and the number of post-wiping cycles is stored as a comparison variable with a defined degree of precipitation. This means that there is always a clear assignment of the degree of precipitation and the number of permissible and planned wiping cycles when wiping the intervals. If the predetermined constellation of the monitored number of wiping cycles during interval wiping and the comparison variable, namely the stored permissible wiping cycles during interval wiping at a certain degree of Precipitation, the corresponding message is sent to the vehicle driver in particular.
- the message is sent to an optical and / or acoustic reproduction device for reproducing the condition of the squeegee, in particular to the vehicle driver. This ensures that the vehicle operator notices the message and can arrange for the wiper blade or wiper blade to be replaced.
- the message varies depending on the degree of the condition of the squeegee. It is conceivable that the state of the squeegee is subdivided into several sub-states, as a result of which the vehicle driver can always be informed about the current state of his squeegee. The driver can then predict in the long term when a squeegee replacement will be necessary.
- the time-variable influencing variables are reset when the wiper blade or the wiper rubber is replaced. It is conceivable that, for example, when the wiper blade or the wiper blade is replaced, the reset is carried out manually. Alternatively, when the wiper blade or wiper blade is replaced, an automatic wiper blade detection can take place by means of a corresponding sensor, which causes the corresponding influencing variables to be automatically reset.
- a particularly preferred exemplary embodiment of the invention monitors the wiping cycles when wiping the intervals, the installation time of the wiper blade and the number of total wiping cycles of the wiper blade since installation as influencing variables.
- the state of the wiper blade of the wiper blade for the vehicle can be determined very reliably, in particular, from these three influencing variables.
