摘要:
A method of operating a drive-train comprising an auxiliary output on the engine side that can be coupled to the combustion engine via a continuously variable transmission and a generator such that when the engine is running, the generator can be driven at a constant rotational speed regardless of the speed of the engine, such that a condition parameter of the auxiliary output is regulated between a pair of limit values. The condition parameter is regulated as a function of its current actual value, the limit values of the condition parameter and also as a function of a current and/or anticipated driving situation such that parameters are determined, in the regulator, for the energy input into the auxiliary output as a function of these input data, and hence for a corresponding energy uptake from the engine.

摘要:
A method for driving a parallel hybrid drive train of a motor vehicle with at least one internal combustion engine, one electric motor and an output. The electric motor is arranged in the drive train between the output and the internal combustion engine. A shifting element is arranged between the internal combustion engine and the electric motor. A hydrodynamic torque converter is arranged between the electric motor and the output. A target output torque applied at the output is subject to the slip hydrodynamic torque converter, is produced by at least the internal combustion engine and the electric motor, and is determined with reference to at least the required target output torque, an actual turbine speed of the hydrodynamic torque converter, or a an equivalent speed of the parallel hybrid drive train, and the actual speed of the electric motor.
摘要:
A method of operating a drive-train of a motor vehicle having a hybrid drive with an internal combustion engine and an electric machine, an electrical energy accumulator that can be charged when the electric machine operates as a generator and discharged when the electric machine operates as a motor, a transmission connected between the hybrid drive and a drive output, and at least one auxiliary power takeoff on either the transmission or the hybrid drive side such that the auxiliary power takeoff can be operated with variable energy demand within functional capability limits that depend on the auxiliary power takeoff. Depending on the current operating status of the hybrid drive unit, the electrical energy accumulator and/or the auxiliary power takeoff, energy available in the drive-train, but not required at the drive output, can bypass the electrical energy accumulator and be stored in the auxiliary power takeoff.
摘要:
A method of operating a drivetrain of a motor vehicle. The drivetrain comprises a drive aggregate formed as a hybrid drive with a combustion engine and an electric machine, and a transmission connected between the drive aggregate and a drive output. The drivetrain also comprises a pressure reservoir system with at least one pressure reservoir and at least one pressure generator by the combustion engine in order to fill the pressure reservoir. A pressure in the pressure reservoir of the pressure reservoir system is measured and a value of the actual pressure, in the pressure reservoir system, is compared with at least one threshold value. When the actual pressure value is higher than a threshold value, stopping of the combustion engine is permitted, whereas if the actual pressure value is lower than the threshold value, stopping of the combustion engine is not permitted.
