Title:
ベルト式自動変速機のベルト交換時期報知装置
Document Type and Number:
Japanese Patent JP4067769
Kind Code:
B2
Abstract:
The invention improves the maintainability of the vehicle by identifying the wear conditions of the endless belt correctly and informing the driver of the right timing of belt replacement clearly in the belt-type automatic transmission mounted on the vehicle. To achieve this, the belt replacement timing annunciator of the belt-type automatic transmission in which the radii of the endless belt wound around the drive pulley and around the driven pulley vary to shift the change gear ratio comprises operating conditions detecting means S4, S5 for detecting a specific operating condition of the vehicle, change gear ratio detecting means S6 for detecting the actual change gear ratio R of the automatic transmission, determination means S7-S10 for determining that the endless belt is at the right timing to be replaced when the state in which the change gear ratio R exceeds the reference change gear ratio Ro set to the value larger than the predetermined change gear ratio has continued for a predetermined time period to, and display means for displaying the result of determination.
