Title:
CONTACT POINT DETERMINATION
Document Type and Number:
WIPO Patent Application WO/2015/086013
Kind Code:
A3
Abstract:
The invention relates to a transmission comprising an input shaft, a transmission shaft, a clutch for connecting the input shaft with the transmission shaft, an output shaft, a pair of gear wheels for torque-transmitting coupling of the transmission shaft to the output shaft, and an electric motor which is connected to the transmission shaft. A method for determining a contact point of the clutch comprises steps of releasing the clutch, deactivating the torque-transmitting coupling of the pair of gear wheels to the transmission shaft or to the output shaft, determining a first speed gradient of the transmission shaft in a first phase, partially engaging the clutch, determining a second speed gradient of the transmission shaft in a second phase, and determining a probe point of the clutch on the basis of the two gradients. To this end the electric motor is activated during both phases in order to transmit a predetermined torque to the transmission shaft.
