Abstract: An active accelerator pedal for a vehicle includes a pedal unit and an actuator unit. The pedal unit includes a pedal that is pivotable about a pivot axis. The actuator unit includes an electrical device and a worm gear positioned between the electrical drive and the pedal unit. The worm gear includes a worm and a driven worm element. The actuator unit is configured to apply a counterforce in a direction opposite to a pedal force exerted on the pedal.

Abstract: The invention relates to an air conditioning compressor (1) for a vehicle (24), in particular a motor vehicle (25), having a compression chamber (18) having an inlet (7) for a cooling medium to be compressed and an outlet (8) for the compressed cooling medium, wherein a wall of the compression chamber (18) is formed at least in sections by a translationally displaceable piston (3). According to the invention, the end of the piston (3) facing away from the compression chamber forms at least one wall region of a control pressure chamber (19). The invention further relates to a vehicle having an air conditioning apparatus.

Abstract: The fuel injection device for an internal combustion engine comprises a feed pump which has an electric drive, by which feed pump fuel is fed from a fuel storage tank into a low-pressure region to the suction side of at least one high-pressure pump. The high-pressure pump pumps fuel into a high-pressure region in which at least one injector is provided to inject the fuel into the internal combustion engine. The fuel injection is controlled by an electric control device. Arranged in the low-pressure region is a pressure sensor which is connected to the control device. The electric drive of the feed pump is activated by the control device in order to set a feed quantity of the feed pump which is variable as a function of at least one operating parameter of the internal combustion engine and/or of the high-pressure pump.

Abstract: The invention relates to a mobile hydraulic system for a hybrid vehicle, comprising a hydraulic accumulator device (22), which comprises a high-pressure accumulator chamber (34) and a low-pressure accumulator chamber (35), between which a hydraulic drive unit is connected, wherein the hydraulic drive unit is used to convey an incompressible fluid from the low-pressure accumulator chamber (35) into the high-pressure accumulator chamber (34) in an accumulator operating state, wherein the incompressible fluid can be discharged from the high-pressure accumulator chamber into the low-pressure accumulator chamber (35) in a drive operating state in order to hydraulically drive the hydraulic drive unit.

Abstract: The invention relates to a hybrid drive system comprising an internal combustion engine (11) which is operated using fuel (21) from a fuel tank (20), and comprising a hydraulic machine (12) which interacts with a hydraulic energy store (38). In order to provide a hybrid drive system which requires less installation space than conventional hybrid drive systems, the hydraulic machine (12) is operated with the same fuel (21) with which the internal combustion engine (11) is also operated.
