Abstract
A method for starting an internal combustion engine using a starter generator to which the engine is connected via a belt drive, the belt drive including a belt pulley of the starter generator, a belt pulley of the internal combustion engine, and a belt connecting the belt pulleys in a torque-transmitting manner, includes operating the starter generator such that its drive torque output to the belt pulley of the starter generator is according to a drive torque curve by which an output torque generated temporarily on the belt pulley of the internal combustion engine exceeds the drive torque of the starter generator, taking a gear ratio of the belt drive into consideration.

A method for starting an internal combustion engine using a starter generator to which the engine is connected via a belt pulley of the starter generator, a belt pulley of the internal combustion engine, and a belt connecting the belt pulleys in a torque-transmitting manner, the method comprising:
- the starter generator operating such that its drive torque output to the belt pulley of the starter generator is according to drive torque curve by which, taking a gear ratio of the belt drive into consideration, an output torque generated temporarily on the belt pulley of the internal combustion engine exceeds the drive torque of the starter generator.
A device comprising:
- processing circuitry;
- and
- an interface to an engine-generator system that includes a starter generator to which an internal combustion engine is connected via (a) a belt pulley of the starter generator, (b) a belt pulley of the internal combustion engine, and (c) a belt connecting the belt pulleys in a torque-transmitting manner;
- wherein the processing circuitry is configured to generate, and output to the engine-generator system, control output that operates the starter generator such that its drive torque output to the belt pulley of the starter generator is according to drive torque curve by which, taking a gear ratio of the belt drive into consideration, an output torque generated temporarily on the belt pulley of the internal combustion engine exceeds the drive torque of the starter generator.
A non-transitory computer-readable medium on which are stored instructions that are executable by a processor, the instructions which, when executed by the processor, cause the processor to perform a method for starting an internal combustion engine using a starter generator to which the engine is connected via a belt pulley of the starter generator, a belt pulley of the internal combustion engine, and a belt connecting the belt pulleys in a torque-transmitting manner, the method comprising:
- operating the starter generator such that its drive torque output to the belt pulley of the starter generator is according to drive torque curve by which, taking a gear ratio of the belt drive into consideration, an output torque generated temporarily on the belt pulley of the internal combustion engine exceeds the drive torque of the starter generator.
