Title:
無段変速機の変速比調整系
Document Type and Number:
Japanese Patent JP3974216
Kind Code:
B2
Abstract:
A system for adjusting the gear ratio of a transmission is continuously adjusted with respect to its gear ratio and mounted downstream of the vehicle motor. Furthermore, downhill travel is detected and the adjustment of the gear ratio of the transmission is made in dependence upon the detected downhill travel. The system is are provided for adjusting the gear ratio in reaction to the detected downhill travel in such a manner that the transmission input rpm and/or the engine rpm increases in a pregiven manner. The advantage of the system is that the transition from normal operation (no downhill travel) to the downhill travel function of the system takes place at first unnoticeable for the driver because the engine rpm increases in a manner not unexpected for the driver.
