Abstract: A method is provided for driving a half bridge circuit that includes a first transistor and a second transistor that are switched in a complementary manner. The method includes generating an off-current during a plurality of turn-off switching events to control a gate voltage of the second transistor; measuring a transistor parameter of the second transistor during a first turn-off switching event during which the second transistor is transitioned to an off state, wherein the transistor parameter is indicative of an oscillation at the first transistor during a corresponding turn-on switching event during which the first transistor is transitioned to an on state; and activating a portion of the off-current for the second turn-off switching event, including regulating an interval length of the second portion for the second turn-off switching event based on the measured transistor parameter measured during the first turn-off switching event.

Abstract: A method to a computer program containing instructions and to a module for monitoring a component of a control system for a transport. In a first step, a function call is sent to the component to execute a function used by the component using defined input data. Then a response from the component to the function call is received. The response is subsequently compared with an expected response. Finally, an action is performed in response to a result of the comparison.

Abstract: A method for locating a portable radio unit (TF) within a predetermined area (AB, IB) of a vehicle (FZ) has the following steps. A first radio signal (FS1) is transmitted from a vehicle-based position (PO1) outside the vehicle. Further, a second radio signal (FS2) is transmitted from a vehicle-based position (PO2) inside the vehicle. Values (R1, R2) of the respective measured reception field strengths of the first and second radio signals at the location (OF) of the portable radio unit or a value derived therefrom is/are received. Finally, the location (OF) of the portable radio unit is ascertained on the basis of a comparison of the values of the respective measured reception field strengths. In this manner, a simple and reliable way of locating a portable radio unit is also made possible using radio-frequency radio signals.

Abstract: The invention relates to a method for verifying a prescribed maximum physical distance (MAX) of a radio key (11) in relation to a motor vehicle (10), wherein a control apparatus (26) uses a radio device (21) of the motor vehicle (10) to transmit at least one electromagnetic radio signal to the radio key (11) and subsequently receives a respective electromagnetic response signal and, for each radio signal, takes the radio signal and the associated response signal as a basis in each case for using a signal propagation delay measurement to ascertain a respective signal propagation delay and checks whether the signal propagation delay fails to satisfy a predetermined propagation delay criterion (27), and signals a transgression above the propagation delay (28) when the propagation delay criterion (27) is not satisfied.

Abstract: An apparatus and a method for locating a mobile terminal, in particular a mobile radio terminal for a cellular mobile radio network by way of an apparatus of a motor vehicle. The mobile terminal sets up a connection to at least one first receiver, while the mobile terminal does not set up a connection to the at least one further one of the receivers at least for this locating operation. Both the at least one first receiver and at least one of the further ones of the receivers each determine a field strength of at least one radio signal transmitted by the mobile terminal or a first receiver. The field strengths thus determined are used to locate to locate the mobile terminal.

The steering column may further comprise fastening elements for fastening the steering column on the vehicle body. The steering column may include a pivot bearing for height adjustment of the steering column. The pivot bearing may be provided on a region of the steering column that is remote from the steering wheel. Further, the pivot bearing may be disposed or formed in a supporting element that is fastened non-releasably on the casing tube.

Abstract: A steering column may comprise a casing tube and a steering spindle that is mounted in the casing tube so as to be rotatable about a longitudinal axis of the casing tube. Because the casing tube may be an outer casing tube that has a non-circular inner cross section and because an adaptor may be manufactured from metal as an extruded part and may comprise an outer circumferential configuration that is compatible with an inner cross section of the casing tube and an interior annular bearing seat, the adaptor can be inserted into the outer casing tube and can be fastened there.

The method may involve, amongst other steps, manufacturing at least one single blank of the outer steering column tube and/or of the inner steering column tube using an extrusion process.

Abstract: A keyless access system for a motor vehicle, which includes a portable signal generator for access to one or more doors or flaps of the motor vehicle, wherein the signal generator transmits an enable signal to a receiver unit, mounted on the motor vehicle, by a short-range radio link. The receiver unit permits access to one or more doors or flaps if it is determined that the enable signal is valid and a distance criterion which represents a distance between the signal generator and the motor vehicle is satisfied. The distance criterion results from a comparison of a weighted reception field strength of the short-range radio link between the signal generator and the receiver unit with a threshold value.
