A method for programming a wiper system for operating a vehicle windscreen wiper where a wiper module on the driver's side is programmed as a master module and a wiper module on the passenger's side is programmed as a slave module. The wiper modules include a reversing motor, a gear, a holder, and a control. A program sequence, vehicle-specific characteristic data and data for the operation of the wiper module as master or slave module are stored in the control. The wiper module on the driver's side is connected via an on-board wiring system interface and a first data communication line with a vehicle control unit. Provision is made that before the activation of the wiper module on the driver's side via the first data communication line in its control the wiper module is defined or respectively pre-programmed neither as master module nor as slave module.

Method for programming a wiper system for vehicle windscreens and wiper system

A method for the activation of a windscreen wiper motor is disclosed, in which the motor is connected to a wiper blade by a drive shaft, which moves the wiper blade between two reversal points of a wiping field in differing movement direction, where the rotation speed and direction of the motor, or the speed of the wiper blade, is detected by a sensor device and is supplied to a control device as an input value. The motor, before reaching the respective reversal point, is switched off, whereupon the drive shaft continues to rotate further by a castor angle up to a standstill, and the wiper blade moves further by a trailing distance. The actual speed of the wiper blade is compared at the switch-off time with a nominal speed, and the motor is operated further for a period of time when the comparison results in a difference in values.

The invention relates to a method for programming a wiper system () for vehicle windscreens, in which for operating respectively a windscreen wiper () a wiper module () on the driver's side is programmed as master module () and a wiper module () on the passenger's side is programmed as slave module (), wherein the wiper modules () consist of a reversing motor (), if applicable a gear (), a holder () for fastening to the body of a vehicle, and a control (), wherein in the control () at least data for a program sequence (), vehicle-specific characteristic data () and data for the operation of the wiper module () as master module () or respectively as slave module () are stored, wherein at least the wiper module () on the driver's side is connected via an on-board wiring system interface () and a first data communication line () with a vehicle control unit (). According to the invention, provision is made that before the activation of the wiper module () on the driver's side via the first data communication line () in its control () the wiper module () is defined or respectively pre-programmed neither as master module () nor as slave module ().

The invention relates to a rotation angle measuring device for an electrical machine. To provide a simple and compact measuring device of this kind, the invention provides for the commutator of the machine to be magnetized and for the magnetic field which rotates with the commutator to be evaluated by means of a suitable sensor. Advantageous improvements relate to a suitable structure for the commutator.
