Title: Transmission controller for continuously variable transmission
Inventor: MINAGAWA YUSUKE
IPC: F16H61/10
Filed: 1996-06-20
Abstract: PROBLEM TO BE SOLVED: To suppress a transmission shock at the time of kick-down acceleration and so on, by changing a gear shifting speed according to relationship of magnitude between the present actual driving torque and a target driving torque according to a target transmission gear ratio. SOLUTION: When transmission control means 102 changes a target transmission gear ratio, a target driving torque on the basis of this target transmission gear ratio, and the actual driving torque are respectively calculated, and gear shifting speed changing means 105 varies and controls a gear shifting speed according to relationship of magnitude between the actual and target values of each driving torque. For example, in the case that a driver steps on an accelerator pedal so as to kick-down accelerate, the gear shifting speed is changed to a high level if difference between the target driving torque and the actual driving torque is large and changed to a low level if this difference is small, thereby rapid acceleration can be performed while suppressing a transmission shock due to the fluctuation of an inertia torque.  Hereby, the operativity of a vehicle equipped with a continuously variable transmission can be improved.
