Title:
TRANSMISSION CONTROL DEVICE AND TRANSMISSION CONTROL METHOD
Document Type and Number:
Japanese Patent JP2017116031
Kind Code:
A
Abstract:
PROBLEM TO BE SOLVED: To protect synchronization mechanisms of both a main transmission mechanism and a range type transmission mechanism.SOLUTION: A control device for a manual transmission 20 with a main transmission mechanism 30 arranged at an input side and a range type transmission mechanism 60 arranged at an output side comprises: an input shaft rotation speed sensor 90; an output shaft rotation speed sensor 91; and a TCU 100 which prohibits switching operation of the range type transmission mechanism 60 when a synchro rotation speed difference at a side of the main transmission mechanism 30, which can be calculated from an input shaft rotation speed detected by the input shaft rotation speed sensor 90 and an output shaft rotation speed detected by the output shaft rotation speed sensor 91 on the assumption that a range is switched, is not less than a first threshold.SELECTED DRAWING: Figure 2
