Title:
CONTROL FOR STEPLESS SPEED CHANGE GEAR FOR CAR
Document Type and Number:
Japanese Patent JPS59217047
Kind Code:
A
Abstract:
PURPOSE:To improve acceleration performance and fuel consumption efficiency by making the gear-change speed of a stepless speed change gear to be the increasing function of the difference between an aimed engine speed and an actual engine speed. CONSTITUTION:The gear-change speed (e) of CVT is made to be the increasing function of the difference Ne'-Ne between an aimed engine speed Ne' and an actual engine speed Ne. Therefore, when the value Ne'-Ne is large, namely when large acceleration is needed, the gear-change speed (e) increases, and large acceleration is realized. When Ne'-Ne is small, namely when large acceleration is not needed, the gear-change speed (e) becomes small, and fuel consumption efficiency is improved.
