Title:
CONTROLLING METHOD OF AUTOMATIC TRANSMISSION
Document Type and Number:
Japanese Patent JPS6011754
Kind Code:
A
Abstract:
PURPOSE:To reduce synchronous load prior to synchronous operation prevent the occurrence of undersynchronization, by detecting size of the synchronous load during transmission gearing, and when the load is too much against the capacity of a synchronizer, making it perform double clutch operations. CONSTITUTION:In a processor 9a, an absolute value of a difference between an output shaft speed N1 and an input shaft speed N0 detected by a car speed sensor 8b and an input shaft speed sensor 8a is set down as synchronous load M, and this synchronous load M is compared with a prestored setting synchronous load value DELTAN. And, when M>=DELTAN, that is, the synchronous load is discriminated to be exessiveness, the processor 9a transmits a clutch driving signal CDV to a clutch actuator 3 via an output port 9c, making a clutch 2 into engagement. With this constitution, an engine 1 and a transmission 6 are connected with each other, thus the synchronous load is reduced.
