摘要： A device is provided for determining a steering torque in a motor vehicle. The device includes a first shaft a second shaft, a twistable means of connection, a stator means, a multi-pole magnetic means, and a first sensor means and a second sensor means. The first shaft is connected to the second shaft via the twistable means of connection, and the magnetic means is fixed to the first shaft. The stator means is fixed to the second shaft, and the first sensor means is designed for measuring, in the case of a relative rotary movement of the magnetic means relative to the stator means, a first magnetic flux density in a first direction. The second sensor means is designed for measuring, in the case of the relative rotary movement of the magnetic means relative to the stator means, a second magnetic flux density in a second direction. The second direction is opposite to the first direction, and the second sensor means is arranged to be rotationally offset by more than 90° relative to the first sensor means.

摘要： A pedal emulator (20, 100) is provided. The pedal emulator includes an emulator piston (28, 102) coupled to a damper (46, D1) that is contained within a housing (22, 104). The damper is surrounded by first (34, S1) and second (38, S2) springs that are carried by a lower spring seat (114), the lower spring seat being upwardly biased by a third spring (S3), for example a wave spring. The first and second springs and the third spring cooperate to provide a counter-force that is tailored to the desired feel of the pedal. First and second sensors measure travel (72, 74) and force in response to downward compression of the emulator piston, and the damper provides hysteresis upon return travel of the emulator piston. A method comprising: providing a brake pedal emulator (100) including an emulator piston (102), the emulator piston (102) being operatively coupled to a brake pedal, wherein the brake pedal emulator (100) is adapted to provide a first force response during a first portion of travel of the emulator piston (102) and a second force response during a second portion of travel of the emulator piston (102); detecting a sequence of actuations of the brake pedal using the brake pedal emulator (100) for conversion into a selected driver input command; and providing vibratory feedback to the brake pedal using a haptic actuator, the vibratory feedback being in response to the selection of a driver input command.

摘要： A device, a system, a configuration process, and an operating procedure are provided for the electric control of at least one real electric consumer of a motor vehicle. In order to design in a more flexible manner the electric control of at least one electric consumer of a motor vehicle, the device is implemented as a configurable device. Correlations between a plurality of actions and operating settings of a plurality of hypothetical electric consumers are stored. At least one action is selectable depending on the at least one input signal (I), and the at least one electric output of the device allocable to the at least one real electric consumer can be activated depending on the operating setting of the at least one hypothetical electric consumer allocated to the selected action.

摘要： A system having a cover for a motor vehicle, in particular a fuel cap or a charging port cover, an electromotive actuator with an output and an electric motor, and an electric motor controller, wherein the electric motor of the actuator can be controlled via the motor controller as a function of an electric actuation signal such that the output of the actuator transfers the cover to an open position or a closed position. In order to realize the automatic opening or closing of a cover for a motor vehicle using simple circuit technology, it is proposed that the actuation signal can be generated by an external movement of the output. Furthermore, a method for automatically actuating a cover is provided.

摘要： An improved method for zero-voltage switching (ZVS) of a voltage-fed half-bridge using a variable dead band is provided. The duration of the dead band is determined dynamically and is precisely long enough to ensure the absence of shoot-through events while also minimizing or eliminating switching losses and reverse conduction losses. The method generally includes: (a) calculating the equivalent capacitance as seen by the current source charging the midpoint of the half-bridge; (b) calculating the ZVS charge requirement based on the link voltage and the equivalent capacitance; (c) calculating the charge delivered by the current source over time during a dead band vector, equating the result to the ZVS charge requirement, and solving for the ZVS time requirement at each commutation point over the switching cycle; and (d) updating the dead bands for each commutation of each half-bridge in the switched-mode power converter.
