IPC: F16H61/16
Filed: 1997-11-27
Abstract: PROBLEM TO BE SOLVED: To prevent a shock and abnormal sound at coast down shift time, without deteriorating fuel consumption. SOLUTION: In a coast condition, for instance, when a speed change command of a down shift from a 3-speed to 2-speed is generated, a car speed at speed change ending time is estimated, and based on an engine speed at idle time, a car speed range, such that drive force at speed change ending time is a drive, is determined as an inhibition region. When the estimated car speed is in the inhibition region, that is, in the point of time P ending a speed change, when drive force is positive, the concerned coast down shift is inhibited till a speed change command to the next low speed shift. In this way, with the lapse of time, when a transfer is to a speed change of 1-speed shift, the concerned speed change is ended during the time in a condition of drive force 0, and a shock and abnormal sound are prevented in a drive system one-way clutch.
