Title:
CONTROLLER OF DRIVING GEAR FOR VEHICLE
Document Type and Number:
WIPO Patent Application WO/2005/106290
Kind Code:
A1
Abstract:
A controller of a driving gear for a vehicle, wherein since the reduction gear ratio of a continuously variable transmission part (11) is changed so that the stepwise change of the reduction gear ratio can be suppressed by a hybrid control means (52) even if the reduction gear ratio of a stepped transmission part (20) is changed stepwise in the gear shift control of the stepped transmission part (20), the total reduction gear ratio &gammad T of a transmission mechanism (10) formed based on the reduction gear ratio of the continuously variable transmission part (11) and the reduction gear ratio of the stepped transmission part (20) is continuously changed. As a result, the stepwise change of the rotating speed NE of an engine is suppressed before and after the gear shift control of the stepped transmission part (20) to suppress a shock caused by the gear shift operation. Also, the overall transmission mechanism (10) is allowed to function as the continuously variable transmission, fuel economy can be improved.
