Title:
CONTROL DEVICE FOR STEPLESS SPEED CHANGE DEVICE
Document Type and Number:
Japanese Patent JP2016102566
Kind Code:
A
Abstract:
PROBLEM TO BE SOLVED: To provide a control device for a stepless speed change device capable of restricting occurrence of lack of driving power at the time of travelling of a vehicle under manual shift mode.SOLUTION: Under a manual shift mode, a change gear ratio is changed in a range of 1 to 7 speed stages in response to a shift operation. Under the manual shift mode, inertia travel of a vehicle is continued while a shift operation is not carried out by a driver. When a primary rotation is decreased down to the minimum engine speed guard lines L1, L2, the change gear ratio is increased continuously or in a stepwise manner in such a way that the primary rotation may not become below the minimum engine speed guard lines L1, L2. In addition, when a request for acceleration for accelerating a vehicle is inputted, a correction for increasing the minimum engine speed guard line L1 up to the minimum engine speed guard line L2 is performed.SELECTED DRAWING: Figure 3
