Document Type and Number:
Japanese Patent JP4301211
Kind Code:
B2
Abstract:
To provide a controller for accurately learning the engagement pressure of an engagement device relative to the speed change of a change gear in a driving unit for a vehicle equipped with a differential mechanism and a second motor and a change gear installed on a power transmission path from the differential mechanism to a driven wheel.
When the input rotation speed NINof an automatic transmission part 20 is changed by using a first motor M1 and/or a second motor M2 by a hybrid control means 52 during the speed change of the automatic transmission part 20, the learning value of the engagement pressure of the engagement device is corrected on the basis of the variation of the input rotation speed NINby the hybrid control means 52 by an engagement pressure control means 80. Thus, it is possible to accurately learn the engagement pressure of an engagement device relative to the speed change of the transmission part 20, and to suppress change gear shock when the input rotation speed NINis changed according to the engagement pressure of the engagement device related to the speed change of the automatic transmission part 20, and in addition, even when the input rotation speed NINis changed by the hybrid control means 52.
