An electric arrangement which, for controlling at least two electric motors, has at least one first H-bridge arrangement and a second H-bridge arrangement, is provided. The electric arrangement comprises a first electric motor, which is electrically connected to a first switching element, a second switching element, a third switching element and a fourth switching element in the first H-bridge arrangement. The electric arrangement furthermore comprises a second electric motor, which is arranged in a second bridge branch of the second H-bridge arrangement) and is connected to a third half-bridge via a third motor contact, wherein the third half-bridge comprises a fifth switching element and a sixth switching element.

Electric arrangement and method for controlling of at least two electric motors

A method for operating the electrical system of a motor vehicle having a control unit with an operating mode and an energy-saving standby mode is described. A wake-up operator control event is detected by a sensor and has an associated time interval from the preceding wake-up operator control event. The time interval is ascertained when a wake-up operator control event is detected, and the control unit is woken up or not woken up. Each wake-up operator control event has an associated switch-off indicator which is ascertained each time a wake-up operator control event is detected, and the control unit is woken up or not woken up as a function of the level of the switch-off indicator with reference to a switch-off threshold. A change in the current switch-off indicator relative to the preceding switch-off indicator is all the greater the smaller the current time interval.

Method for operating the on-board electrical power system of a motor vehicle

An electric window lifter of a vehicle with a vehicle door having a frameless window is actuated according to a novel, low-wear actuation method. An entry signal is acquired that allows a conclusion to be drawn about whether a person has entered through this vehicle door. In this case, the window pane that is associated with the window of this given vehicle door is lowered by a short stroke by way of the window lifter in response to a central exit signal only when the entry signal was first identified. The window lifter or power window assembly includes an associated actuation unit with a query module that is configured for automatically carrying out the method.

Actuation method for an electric window lifter, and actuation unit

In order to determine the actuation position of a motor-driven adjusting element of a motor vehicle, a Hall-effect sensor is located in a rotatable magnetic field, wherein a periodic change in the magnetic flux density sensed by the Hall-effect sensor is converted into a binary pulse train in that a pulse transition takes place when an upper switching threshold is positively exceeded and when a lower switching threshold separated from the upper switching threshold by a hysteresis is negatively exceeded. The hysteresis is reduced following an inactive phase of the Hall-effect sensor during which the magnetic field was stationary and/or the Hall-effect sensor was deactivated, if the magnetic flux density at the start of the inactive phase has exceeded the upper switching threshold by no more than a predefined tolerance range.
