摘要:
The invention relates to a method for operating a drive device (1), which for the purpose of providing a driving torque comprises an internal combustion engine having a plurality of cylinders (10, 11, 12, 13) that, during normal operation, supply a respective torque contribution, and at least one electric motor (3) operatively connected to said engine. To this end, in a diagnostic mode a cylinder-selective measurement of at least one characteristic operating variable is carried out, for which purpose in the diagnostic mode only the cylinder (10, 11, 12, 13) to be measured is operated and the torque contributions of the remaining cylinders (10, 11, 12, 13) are simulated by the electric motor (3).

摘要:
A method and a device for controlling a drive unit of a vehicle are provided in which, starting from the comparison of a first acceleration variable, which is calculated at least from the operating state of the drive unit, and a second acceleration variable, an error is detected. The second acceleration variable includes a first component, in the direction of the vehicle longitudinal axis, and a second component, perpendicular to the vehicle longitudinal axis.
摘要:
A method for controlling a vehicle, including determining a speed curve on a coasting route, in order to let the vehicle on the coasting route coast from an actual speed to a setpoint speed, detecting an additional vehicle approaching the vehicle from behind on the coasting route, and raising the speed of the vehicle compared to the determined speed behavior on the coasting route, in order to produce a predetermined threshold distance from the additional vehicle.
摘要:
A device for cooling components, comprising a housing in which a cavity is formed, in which a phase-change material is accommodated, the housing having at least one surface, which is able to be brought into contact with the component to be cooled, and at least one heat-dissipating surface. The cavity accommodating the phase-change material is enclosed by at least one coil, and the phase-change material includes ferromagnetic or magnetizable particles. Furthermore a method for cooling a component using the device is described.

摘要:
A fuel injection device of an internal combustion engine includes a piezoelectric actuator and a valve element that are coupled to one another. The valve element has a pressure stage. An increase in the force acting on the piezoelectric actuator is interpreted as an actual opening of the valve element, and/or a decrease in the force acting on the piezoelectric actuator is interpreted as an actual closing of the valve element, and that these be taken into account at least part of the time in the controlling of the piezoelectric actuator.
摘要:
A method of calculating the voltage setpoint of a piezoelectric element as a function of a rail pressure is provided, in which a corrected voltage setpoint is formed by, among other adjustments, using a multiplier as a function of a temperature of the piezoelectric element. Additional adjustments for forming the corrected voltage setpoint includes adjusting the setpoint control voltage by multiplication by at least one correction value (multiplier) and/or by addition of at least one correction value (addend).
摘要:
A method of charging or discharging a piezoelectric element, in which electric charge carriers are transported back and forth between a supply voltage of a direct voltage source and a piezoelectric element in order to transmit an elastic deflection of the piezoelectric element to an actuator. An actuating movement of the actuator is modified as a function of the level of a voltage being applied to the piezoelectric element, a reduction of the level of the applied voltage being compensated for by at least one additional transmission of electric charge carriers during a holding phase of the piezoelectric element.
