Method for operating hybrid drive system of hybrid vehicle and control device

Abstract

The invention relates to a method for operating the hybrid drive system of a hybrid vehicle and a control device (20). According to at least one signal provided by one part of a hybrid vehicle (34), the start of the hybrid vehicle (34), which is static before the identification or prediction. During the operation period of the driving motor (14) of the hybrid drive system, through the rotation orlinkage of a crankshaft (12), the crankshaft (12) of the burning motor (10) of the hybrid drive system rotates to an initial position of the crankshaft (12) relative to the burning motor (10); from the moment when the crankshaft (12) exists on the initial position, the ejection valve an the ignition coil of the burning motor (10) can be controlled by the electronic device of the hybrid drive system to burn the burning motor (10); and after the hybrid vehicle (34) is started, the crankshaft (12) is rotated to the initial position.

Description

technical field

[0001] The invention relates to a method for operating a hybrid drive system of a hybrid vehicle. Furthermore, the invention relates to a control device for a hybrid drive system of a hybrid vehicle and a hybrid drive system for a hybrid vehicle. Background technique

[0002] EP 0 939 859 B1 describes a motor vehicle drive comprising a combustion motor and an electric machine. In order to start the combustion motor, the crankshaft and the camshaft, which is mechanically fixed to the crankshaft, are started to rotate by means of an electric motor, which is mechanically connected to the crankshaft. Not only on the crankshaft, but also on the camshaft are gear wheels with a special tooth profile, which are evaluated by sensors. At certain rotational angles, the crankshaft and camshaft reach positions in which a specific position can be determined by means of a special pattern on the corresponding sensor wheel. The injection and ignition of fuel can only be re...
