Embodiment Construction

[0036] exist figure 1 A device 100 with an internal combustion engine 110 and an electric machine 120 is schematically shown, with which the method according to the invention can be carried out. Internal combustion engine 110 is designed as an exemplary internal combustion engine with cylinders 111 and crankshaft 115 .

[0037] Electric machine 120 is torque-transmittingly coupled to crankshaft 115 and thus also torque-transmittingly coupled to internal combustion engine 110 . Furthermore, the electric machine 120 is electrically connected to an energy store 130 , which can be a battery, for example, ie electrical energy can flow from the electric machine 120 to the energy store 130 and vice versa. Furthermore, the vehicle electrical system can be electrically connected to energy storage device 130 .

[0038] By means of the computing unit 140 designed as a controller, the electric machine 120 can be controlled accordingly, that is to say a torque-absorbing or generator-like...

Abstract

The invention relates to a method for operating a device having an internal combustion engine and a motor. The internal combustion engine has a crankshaft and the electric machine is coupled to the crankshaft in a torque-transmitting manner, the motor is electrically connected with the energy accumulator. The motor is actuated in such a way. The internal combustion engine is designed such that anacceleration torque is applied to the crankshaft by the internal combustion engine in a first range of a working cycle of the internal combustion engine, and a torque which acts more strongly on the crankshaft than in a second range of the working cycle is applied to the crankshaft by the electric machine.

Description

technical field [0001] The invention relates to a method for operating a device having an internal combustion engine and an electric machine, wherein the internal combustion engine has a crankshaft and the electric machine is torque-transmittingly coupled to the crankshaft, the electric machine is electrically connected to an energy store, and the present invention The invention relates to a computing unit and a computer program for carrying out the method. Background technique [0002] In internal combustion engines, the rotational speed is increased by the kinetic energy generated during the working stroke, and the rotational speed is reduced by the subsequent exhaust stroke, intake stroke and compression stroke. This also produces certain rotational speed fluctuations within the working cycle of the cylinders of the internal combustion engine. [0003] The higher the number of cylinders of the internal combustion engine for which the working strokes are also offset relat...
