Title:
METHOD FOR INCREASING THE AVAILABILITY OF A HYBRID SEPARATING CLUTCH IN A HYBRID DRIVE TRAIN OF A MOTOR VEHICLE
Document Type and Number:
WIPO Patent Application WO/2015/090307
Kind Code:
A3
Abstract:
The invention relates to a method for increasing the availability of a hybrid separating clutch in a hybrid drive train of a motor vehicle, wherein the hybrid separating clutch is disposed between an internal combustion engine and an electric traction drive. In a method where even in the event of a fault the motor vehicle continues to be driven, the hybrid separating clutch is controlled by means of a hydrostatic actuator, wherein when a malfunction of the hydrostatic actuator is detected, for actuation of the hybrid separating clutch which is engaged in the non-actuated state, the last state of the hydrostatic actuator detected by a control mechanism is used for estimation of a minimum clutch torque which can be transmitted.
