Abstract
A method for operating a belt-driven starter generator of an internal combustion engine, in which a time interval between an onset of a rotary motion of the belt-driven starter generator and an onset of a rotary motion of the internal combustion engine is determined, the determined time interval is compared to a reference value, and the structural change of a belt of the belt-driven starter generator is inferred therefrom, and a torque of the belt-driven starter generator and/or a torque of a component connected to the belt is restricted as a function of the structural change of the belt.
Claims12
A method for operating a belt-driven starter generator of an internal combustion engine, comprising:
- determining a time interval between an onset of a rotary motion of the belt-driven starter generator and an onset of a rotary motion of the internal combustion engine;
- comparing the determined time interval to a reference value and inferring a structural change of a belt of the belt-driven starter generator from the comparison;
- and
- restricting, as a function of the structural change of the belt, at least one of:
- (i) a torque of the belt-driven starter generator, and (ii) a torque of a component connected to the belt.
An arithmetic unit, designed to operate a belt-driven starter generator of an internal combustion engine, the arithmetic unit designed to:
- determine a time interval between an onset of a rotary motion of the belt-driven starter generator and an onset of a rotary motion of the internal combustion engine;
- compare the determined time interval to a reference value and inferring a structural change of a belt of the belt-driven starter generator from the comparison;
- and
- restrict, as a function of the structural change of the belt, at least one of:
- (i) a torque of the belt-driven starter generator, and (ii) a torque of a component connected to the belt.
A non-transitory machine-readable storage medium on which is stored a computer program having program code for operating a belt-driven starter generator of an internal combustion engine, the computer program, when executed by a processor, causing the processor to perform:
- determining a time interval between an onset of a rotary motion of the belt-driven starter generator and an onset of a rotary motion of the internal combustion engine;
- comparing the determined time interval to a reference value and inferring a structural change of a belt of the belt-driven starter generator from the comparison;
- and
- restricting, as a function of the structural change of the belt, at least one of:
- (i) a torque of the belt-driven starter generator, and (ii) a torque of a component connected to the belt.
