Abstract
In a method, a device, a computer program and a computer program product for operating an internal combustion engine having a starter: a first threshold value and a second threshold value are specified; a first variable and a second variable are determined, which characterize the operating state of the internal combustion engine; the first variable is compared to the specified first threshold value and the second variable is compared to the specified second threshold value; and the starter starting, or not starting, the internal combustion engine as a function of the comparison result.
Claims14
A method for operating an internal combustion engine having a starter, comprising:
- specifying a first threshold value and a second threshold value;
- determining a first variable and a second variable, which characterize an operating state of the internal combustion engine;
- at least one of (a) comparing the first variable to the specified first threshold value and (b) comparing the second variable to the specified second threshold value;
- and
- one of (a) starting and (b) not starting, by the starter, the internal combustion engine as a function of the comparison.
A device for operating an internal combustion engine having a starter, which is situated on a crankshaft of the internal combustion engine, comprising:
- a first setpoint selection device adapted to specify a first threshold value;
- a second setpoint selection device adapted to specify a second threshold value;
- a first determination device adapted to determine a first variable, which characterizes a run-down of the internal combustion engine;
- a second determination device adapted to determine a second variable, which characterizes a run-down of the internal combustion engine;
- a comparator adapted to compare at least of (a) the first variable to the specified first threshold value and (b) the second variable to the specified second threshold value;
- and
- a third setpoint selection device adapted to operate the starter by the crankshaft as a function of the comparison.
