Embodiment Construction

[0015] figure 1 Schematically shows a motor vehicle drive train with an internal combustion engine 1, a shock absorber 3 connected to the crankshaft 2 of the internal combustion engine 1, an overrunning clutch 5 and a separating clutch 6, and a stator 8 and a rotor 7 with an electric drive Hybrid module 4, transmission 9, differential 10 and wheels not shown in detail. Two parallel torque transmission systems are arranged between the internal combustion engine 1 and the transmission 9. The first torque transmission system includes the disconnect clutch 6 and the second torque transmission system includes the overrunning clutch 5. The overrunning clutch 5 transmits when torque is transmitted from the internal combustion engine 1 to the transmission 9 and opens when the torque flows from the transmission 9 to the internal combustion engine 1. With the clutch closed, the torque from the transmission 9 to the internal combustion engine 1 can be transmitted. This particularly rela...

Abstract

The invention relates to a method for avoiding unsafe actuation of a disconnect clutch in a hybrid module of a drive train of a motor vehicle, wherein the hybrid module acts between an internal combustion engine and a transmission and has an electric drive, a disconnect clutch and overrunning clutches, and the separating clutch is used to start the internal combustion engine in such a way that the torque provided by the electric drive or drive train is transmitted through a force-locking connection with the electric drive or drive train, or is used for purely electric driving Disconnect the internal combustion engine from the drive train. In a method for avoiding a safety-threatening actuation of a separation clutch in a hybrid module, wherein the safety-threatening driving state is reliably inhibited, the separation clutch is adjusted in dependence on ambient conditions and / or vehicle boundary conditions of the motor vehicle The critical disturbance torque is used to adjust the safety distance to be retained of the open separation clutch.

Description

Technical field [0001] The present invention relates to a method for avoiding safety-endangering operation of a disconnect clutch in a hybrid power module of a drive train of a motor vehicle, wherein the hybrid power module functions between an internal combustion engine and a transmission and has an electric drive, a disconnect clutch And the overrunning clutch, and the separating clutch is used to start the internal combustion engine by means of a force-locked connection with the electric drive or drive train to transmit the torque provided by the electric drive or drive train, or used for pure electric driving. Disconnect the internal combustion engine from the drive train. Background technique [0002] The document DE 10 2012 206 680 A1 discloses a hybrid power module for the drive train of a vehicle. The hybrid power module is arranged between the internal combustion engine and the transmission and has an electric drive, a disconnect clutch and an overrunning clutch, wherei...
