Title:
SHIFT CONTROL DEVICE FOR CONTINUOUS VARIABLE TRANSMISSION
Document Type and Number:
Japanese Patent JPH0681943
Kind Code:
A
Abstract:

PURPOSE: To stabilize behavior of a vehicle with a continuously variable transmission during running on a corner.

CONSTITUTION: The shift speeds Vi of primary and secondary pulleys 26 and 28 are controlled. The change speed DTh of a throttle valve based on drive information of a vehicle, a throttle operation mode responding to the change speed DTh of a throttle valve and the rotation change speed DNp of the primary pulley, a control gain correction amount C responding to a throttle operation mode and the degree Wd of bending, the target number Npo of revolutions of primary pulley responding to a throttle opening, and the deviation number E1 of revolutions being a deviation between the target number Npo of revolutions of primary pulley and the actual number Np of evolutions of primary pulley are determined. A correction control gain GC obtained by multiplying a fundamental control gain responding to the deviation number of revolutions and the control gain correction amount CG, a shift speed Vi based on the deviation number E1 of revolutions and the control gain correction amount CG, and a shift control oil pressure Pc equivalent to the shift speed are calculated, in the order, by a CVTECU being a control means, and the CVTECU is operated to control a hydraulic actuator.
