A method operates a brushed commutator motor of an adjusting drive in a motor vehicle, particularly a window lifter, having a rotor and having a stator. An angular position of the rotor with respect to the stator is determined. The angular position is used to determine a ripple within the torque, which ripple can be expected on the basis of the commutation. The motor current is adapted such that the amplitude of the ripple that can be expected remains below a determined limit value.

An electronic modular unit having electronics has a printed circuit board, a housing receiving the electronics and an electrical conductor. The conductor is in this connection directly soldered with a flat connection end to a contact surface of the printed circuit board. In order to simplify the soldering process, a spring element is arranged in the housing and presses the connection end of the conductor on the contact surface of the printed circuit board for the purpose of fixing the connection end during soldering. The modular unit is, in particular, a capacitive proximity sensor for a vehicle.

An electronic unit has an electronic assembly that comprises a circuit board, and also having a conductor that is connected to said electronic assembly and is provided with a flat connection end. At least one piercing contact protrudes down from the circuit board and connects the conductor electrically to the electronic assembly. The piercing contact penetrates the connection end of the conductor while forming an electrical connection with a conductor track of the conductor. The electronic component is particularly suited as a capacitive proximity sensor for a vehicle.

In the case of a collision protection method for a displaceable vehicle part of a vehicle, during the displacement of the vehicle part, a focused light beam is deflected by a light deflection unit along a predefined scanning path and reflected radiation of the same light beam is detected by a light-sensitive sensor to scan a travel path region upstream from the vehicle part. The presence or absence of an obstruction in the upstream travel path region is concluded on the basis of the reflected radiation, wherein the displacement is stopped or reversed if an obstruction is recognized in the upstream travel path region.

A method measures a capacitance. According to the method, a first detection measurement for the capacitance which is to be measured is detected by a first measurement method during a first measurement phase. In this case, a second measurement phase is started when the first detection measurement satisfies a transition criterion. A second detection measurement for the capacitance which is to be measured is detected during the second measurement phase by a second measurement method which differs from the first measurement method. The second measurement method has higher measurement accuracy than the first measurement method but also greater energy expenditure.

The invention relates to a drive arrangement for the motorized adjustment of a closure element of a motor vehicle, wherein the drive arrangement, in the installed state, is coupled in drive terms to the closure element. It is proposed for the drive arrangement to have at least one drive, which is intended for generating drive movements and in or on which is arranged an acoustic indicator for supplying acoustic feedback to the user.

The invention specifies an anti-trapping device, comprising a motor for driving a pivotable actuating element of a motor vehicle, a sensor for contactlessly identifying an obstacle in the way of the actuating element with an electrode, which has a plurality of segments for producing an external electrical field with respect to a mating electrode and a control unit. The electrode extends in a radial direction with respect to the pivotable actuating element and is split in the radial direction into the plurality of segments, which can each be evaluated separately for the purpose of generating an interference signal. The control unit is designed to drive the motor as a function of an interference signal from one of the segments. Such an anti-trapping device has particularly high flexibility when driving the pivotable actuating element if an obstacle in the way of the pivotable actuating element has been detected.
