Title:
VEHICLE TRANSMISSION CONTROL DEVICE
Document Type and Number:
WIPO Patent Application WO/2014/147918
Kind Code:
A1
Abstract:
The purpose of the present invention is to provide a vehicle transmission control device that detects the relationship of the transmission torque to the pressing force of a joining element when rotation rate control is performed in a motor, enabling learning of the relationship of the transmission torque to the pressing force. The vehicle transmission control device is characterized in that, during learning control by a learning control unit for learning the relationship between the transmission torque and the pressing force in the engagement clutch (83) which acts as a joining element in an automatic transmission (3), a gear change controller (21) for controlling gear changes in the automatic transmission (3) is provided with a differential rotation control unit (configuration for executing the processing in fig. 5) for controlling a rotation rate, when the engagement clutch (83) is joined, using an input rotation rate of the engagement clutch (83) with a pre-set learning differential rotation (dNmo2) applied as a target rotation rate (tNmo2) of a motor generator (MG) for the post-gear-change motor rotation rate (afNmo2) serving as the output rotation rate after the gear change of the engagement clutch (83).
