The invention relates to a windshield wiper device () comprising a driving means () and a control unit () for the driving means (). An operating characteristic map () is provided, in which a maximum torque to be output by the driving means () and a minimum rotational speed of the driving means () are stored.

Windshield wiper device

A system for determining if a tire of a vehicle is improperly inflated. The system includes a radar, a wheel speed sensor, and a controller. The radar is configured to emit a signal to detect a reflection of the signal off of an object positioned perpendicular to the vehicle, and to output an indication of a speed of the vehicle. The wheel speed sensor is configured to sense a speed of a wheel of the vehicle. The controller is configured to receive the indication of the speed of the vehicle from the radar, to calculate a speed of the vehicle based on the sensed speed of the wheel, and to determine a tire of the wheel is improperly inflated when the speed of the vehicle calculated using the wheel speed sensor varies by more than a predetermined amount from the speed of the vehicle determined using the radar signal.

Method for performing closed-loop and/or open-loop control of a windshield wiper device, computer program product, control device and windshield wiper device

Operation of a windshield wiper system for cleaning a windshield of a motor vehicle includes driving at least one wiper by an electric drive motor so that the at least one wiper shifted between two terminal positions, processing by a control unit as the input variable the output signals of a rain quantity and the switching signals of a manually controllable switch mechanism, and processing as the output variable a supply voltage of the electric drive motor so as to control the wiper speed, operating the at least one wiper ( ) with variable intermittent interval times and at variable wiper speeds, as a function of a rain quantity detected by the rain sensor ( ), so that the precisely one wiper speed and precisely one intermittent interval time are associated with each measured rain quantity, and moving the at least one wiper ( ) in an intermittent mode with a lower speed than in a continuous mode.

Windshield wiper system

The invention relates to a windshield wiper drive unit having a drive motor ( ) and a gear ( ) for transmitting a rotary motion of the motor ( ) to the shaft of a windshield wiper, having at least one sensor ( ) for detecting a position of the shaft, and having a control circuit ( ), which receives a detection signal of the sensor ( ) and has one or more inputs ( ) for receiving operating signals that define a desired operating state of the windshield wiper and is arranged to control a sequence of motions of the shaft as a function of the operating signal received, in which the control circuit ( ) is combined with the drive motor ( ) and the at least one sensor to make an integral component unit.

A windshield wiper drive device for driving a windshield wiper ( ) in an alternating motion in a range of motion ( ) between two turning point positions (A, C) includes a motor ( ) for moving the windshield wiper ( ), a detector ( ) for detecting a time at which the windshield wiper ( ) moves past a given position (A, C) in the range of motion ( ), a control circuit ( ) for reversing the direction of motion of the motor ( ) at each turning point position (B, D), and an incremental transducer for detecting the distance traveled by the windshield wiper ( ) from the given position (A, C). The control circuit ( ) reverses the direction of motion of the motor ( ) as soon as it is detected that the windshield wiper ( ) has traveled a defined distance.

Windshield wiper drive device

A windshield wiper mechanism has an electric motor which, subject to a trigger signal of a control circuit, drives a wiping system having at least one wiping space. A consistent wiping sweep is obtained due to the control circuit having a control stage for changing the trigger signal as a function of a wind load.
