Title:
無段変速機の変速制御装置
Document Type and Number:
Japanese Patent JP4270463
Kind Code:
B2
Abstract:
A transmission controller for a continuously variable transmission system steadily returns a gear ratio toward the low-ratio range during deceleration, even in a hybrid vehicle which stops an engine during deceleration. A control unit determines the return-start number of revolutions of a driving pulley and the duty ratio of an actuator and issues a control instruction to the actuator which changes the gear ratio by varying the groove width of the driving pulley. The control instruction is issued after an engine stop instruction from a drive control element and the return-start number of revolutions is set higher as the gear ratio is closer to the top-ratio range.
