Title:
SPEED CHANGE CONTROL DEVICE FOR CONTINUOUSLY VARIABLE TRANSMISSION
Document Type and Number:
Japanese Patent JP3267135
Kind Code:
B2
Abstract:
PROBLEM TO BE SOLVED: To ensure a start acceleration function while restraining variation in target engine rotational speed.
SOLUTION: A speed change control device comprises a target control value setting means 62 for setting a target input speed ne* of a continuous variable transmission 60 in accordance with a vehicle speed VSP and an opening degree TVO of an accelerator pedal, a speed change ratio variation limiting means 63 for restraining variation in the target input speed Ne*, a speed change control means 61 for setting a speed change ratio of the transmission 60 in accordance with the target input speed Ne*, an input speed comparing means 64 for comparing a difference between the target input speed Ne* set by the target control value setting means 62 and an actual input speed Ne, with a predetermined value e0, and a means 65 for inhibiting the restraint to the said variation in speed if the result of the comparison shows that the difference is smaller than the predetermined value e0.
