Title:
METHOD AND DEVICE FOR DETERMINING AN ENGAGEMENT POINT OF A HYBRID CLUTCH IN A HYBRID VEHICLE
Document Type and Number:
WIPO Patent Application WO/2015/188825
Kind Code:
A3
Abstract:
The invention relates to a method for determining an engagement point of a hybrid clutch (4) in a hybrid vehicle; said hybrid clutch (4) is actuated by a hydrostatic clutch actuator (12) and disconnects or connects an internal combustion engine (2) and an electric traction drive (3); the engagement point is determined by slowly actuating the clutch starting from a position in which the hybrid clutch (4) is in the non-actuated state, and monitoring a moment of the electric traction drive (3) when a defined increase in the momentum is detected. In a method in which engagement point adaptation is optimized, a current engagement point (tp) is adapted during operation of the hybrid vehicle using a commissioning routine, by means of which a first engagement point is determined when the hybrid vehicle is commissioned; the hybrid clutch (4) is moved close to a previously determined engagement point, and starting from said last determined engagement point, the hybrid clutch (4) is displaced further until the defined increase in the moment is detected.
