Abstract
A method is described for shutting off an internal combustion engine in a vehicle that comprises an internal combustion engine and an electrical machine, an electrical torque furnished by the electrical machine being adapted in such a way that a change per unit time in a total torque lies within a definable range, the total torque being made up at least of a torque of the internal combustion engine and the electrical torque.
Claims16
A method for shutting off an internal combustion engine in a vehicle that includes an internal combustion engine and an electrical machine, the method comprising:
- adapting an electrical torque furnished by the electrical machine in such a way that a change per unit time in a total torque lies within a definable range, wherein the total torque includes at least a torque of the internal combustion engine and the electrical torque.
A calculation unit, comprising:
- an arrangement for performing a method for shutting off an internal combustion engine in a vehicle that includes an internal combustion engine and an electrical machine, the method comprising:
- adapting an electrical torque furnished by the electrical machine in such a way that a change per unit time in a total torque lies within a definable range, wherein the total torque includes at least a torque of the internal combustion engine and the electrical torque.
A calculation unit, comprising one of:
- a first calculation unit;
- and
- a second calculation unit, wherein one of the first calculation unit and the second calculation unit performs a method for shutting off an internal combustion engine in a vehicle that includes an internal combustion engine and an electrical machine, the method comprising:
- adapting an electrical torque furnished by the electrical machine in such a way that a change per unit time in a total torque lies within a definable range, wherein the total torque includes at least a torque of the internal combustion engine and the electrical torque,
- calculating a target torque of the electrical machine, and
- causing the electrical machine to adjust the electrical torque in accordance with the target torque, wherein a time span of a transfer function of the electrical machine is taken into account in the calculation of the target torque of the electrical machine.
A computer program that causes a calculation unit to carry out a method for shutting off an internal combustion engine in a vehicle that includes an internal combustion engine and an electrical machine, the method comprising:
- adapting an electrical torque furnished by the electrical machine in such a way that a change per unit time in a total torque lies within a definable range, wherein the total torque includes at least a torque of the internal combustion engine and the electrical torque, wherein the computer program is executed on a calculation unit.
A computer program that causes a first calculation unit to carry out, together with another calculation, a method for shutting off an internal combustion engine in a vehicle that includes an internal combustion engine and an electrical machine, the method comprising:
- adapting an electrical torque furnished by the electrical machine in such a way that a change per unit time in a total torque lies within a definable range, wherein the total torque includes at least a torque of the internal combustion engine and the electrical torque.
A machine-readable storage medium having a computer program that causes a calculation unit to carry out a method for shutting off an internal combustion engine in a vehicle that includes an internal combustion engine and an electrical machine, the method comprising:
- adapting an electrical torque furnished by the electrical machine in such a way that a change per unit time in a total torque lies within a definable range, wherein the total torque includes at least a torque of the internal combustion engine and the electrical torque.
