Embodiment Construction

[0019] figure 1 A vehicle 90 with a computing unit 10 according to the invention is shown schematically. The vehicle also has a sensor 50 arranged on the outer contour of the vehicle 90 and a washing device 30 for the sensor 50 . In connection with this, a data link 351 between computing unit 10 and cleaning device 30 is shown, via which data link the computing unit 10 can transmit a first control signal to cleaning device 30 . Optionally, the vehicle 90 also has a first sensing unit 5a and / or 5b for sensing at least one movement of the wiper arm 80a and / or 80b of the vehicle 90 and a first sensing unit 5a and / or 5b for sensing at least one operating parameter of the vehicle 90 The second sensing unit 15 . Here, the wiper arm 80a represents the wiper arm of the front wiper, and the wiper arm 80b represents the wiper arm of the rear wiper. in the figure 1 Among them, the second sensing unit 15 is a rotational speed sensing unit for the wheel 16 a of the vehicle 90 . Also s...

Abstract

The invention relates to a method for controlling at least one washing device of at least one sensor arranged on an outer contour of a vehicle, in which method firstly an implemented vehicle-washing process of the outer contour of the vehicle is identified (140). Here, "sensors" mean e.g. distance sensors which detect the surroundings of a vehicle and are arranged for this purpose on the outer bodywork of the vehicle. An implemented vehicle-washing process leads to the externally attached sensors being cleaned as well and after a vehicle-washing process it can be accordingly assumed that saidsensors are now free of soiling. According to the invention, first control signals for actuating the at least one washing device of the at least one sensor are generated (150) on the basis of an identified vehicle-washing process, which was carried out e.g. in a car wash.

Description

technical field [0001] The invention relates to a method, a computing unit and a vehicle for controlling at least one washing device of at least one sensor arranged on the outer contour of a vehicle. Background technique [0002] Cleaning devices for sensors are known from the prior art. For example, DE 10 2010 055 113 A1 describes a cleaning device having a spray nozzle whose spray area is directed towards an ambient sensor. Such a cleaning device is very important, since soiling of the sensor can lead to a considerable loss of sensor accuracy. For example, a dirty membrane of an ultrasonic sensor can lead to poor vibrations of the membrane. A dirty camera lens can cause the camera to produce inaccurate shots. [0003] Methods for identifying performed vehicle washes are also known from the prior art. This detection is to prevent, for example, automatic switching on of the windshield wipers when the vehicle is in the washer. For example, DE 698 09 508 T2 describes how ...
