Abstract
A vehicle having, in a power transmission path, a continuously variable transmission mechanism and a clutch mechanism, whose torque capacity is smaller than that of the continuously variable transmission mechanism. The vehicle also has a control system to prevent a large torque capacity difference with the continuously variable transmission mechanism and clutch mechanism and to prevent an unnecessary slip of the clutch mechanism by setting an engagement force of the clutch mechanism based on the torque capacity of the continuously variable transmission mechanism. There is also avoided a decline of the learning accuracy of the clutch mechanism by prohibiting a learning control of the clutch mechanism when an engagement force of the clutch mechanism is set based on the torque capacity of the continuously variable transmission mechanism.
