Abstract: A method for controlling a permanently excited synchronous motor, in particular a brushless direct-current motor, having a permanently magnetized rotor and a number of stationary Stator windings to which an alternating voltage of predetermined amplitude and frequency is applied, wherein the frequency of the alternating voltage is determined by the speed of the motor and a phase difference results between the alternating voltage and the alternating current for each Stator winding. Accordingly, current is applied to the Stator windings in such a way that between alternating voltage (UPhase) and alternating current (IPhase) arises a phase angle (?Target, ??Target), which is selected according to speed (?), motor inductance (L), and the power received by the motor.

Abstract: In a radiator module for a motor vehicle, a detachable connection is required between a housing of an electric motor and a retaining structure, which connection allows economic and secure assembly and cannot be loosened or detached by alternating reaction forces at the electric motor. To achieve this, an arrangement is proposed of a retaining structure and detachably connected therewith a housing for an electric motor, in which the housing has a number of radiating protruding tabs on the base side which can be inserted by successive tilt and shift movements in corresponding recesses of the retaining structure. Furthermore various methods for assembly are proposed.

This is achieved by virtue of there being channels provided for air circulation in an interior of the optical system on the basis of the heating of air in the housing by operation of the image sensor, with the channels channeling air around lenses of the optical system. The channels may be along an internal wall of a lens frame of the optical system, and the channels may extend from an end portion of the lens frame at or near the image sensor to an internal space within the lens frame and between two adjacent lens elements of the optical system.

Abstract: A sensor module is mounted at a windshield of a vehicle. The sensor module can be connected, via a fastening section that is arranged on a module housing, to an element that is fixed to the vehicle body or to an element which is connected to a part that is fixed to the vehicle body. A sensor is accommodated in the module housing and is retained such that it can be displaced and/or pivoted from a first starting position into a second end position in order to rest against the windscreen. The adjusting movement can be initiated by an adjusting element which can be preloaded in the direction of the end position by means of a spring element and can be blocked in the starting position by means of a blocking element. Also, a delaying element is provided that can influence a parameter of the adjusting movement.

Abstract: A method for producing a time sequence of images of motor vehicle surroundings from a virtual elevated central perspective on a display wherein several cameras are used to record time sequences of subimage data records from a plurality of real perspectives differently offset and tilted with respect to the virtual perspective. Then, parameterized transformations are applied for obtaining sequences of transformed subimage data records and overall image data for an overall image from the virtual perspective is assembled. Finally, the sequence of the overall image data is displayed as an overall image. To compensate for positional and/or orientation deviations in the recording cameras a selection unit is proposed to recurrently apply a selection criterion for selecting a subimage data record from the sequence and to take this as a basis for redetermining the parameters of the transformations by an optimization method under a quality criterion for the overall image.
