GEAR CHANGE CONTROL DEVICE OF VEHICLE

Title:

GEAR CHANGE CONTROL DEVICE OF VEHICLE

Document Type and Number:

Japanese Patent JP2017198330

Kind Code:

A

Abstract:

PROBLEM TO BE SOLVED: To suppress an incongruity imparted to a driver due to a gear change shock or the like at a gear change of a mechanical stepped gear change part when a gear change control device has an electric stepless gear change part and the mechanical stepped gear change part.SOLUTION: At a simultaneous gear change at which the gear change control of a simulated gear stage is superimposed on the gear change control of a mechanical gear stage, a gear change command output of the simulated gear stage is delayed so that both the gear changes are synchronously performed, both the gear changes are thereby synchronously performed irrespective of a difference of gear change response times, and thus an incongruity imparted to a driver caused by a gear change shock or the like can be suppressed. Furthermore, when the simulated gear stage is singly gear-changed, since a gear change command is outputted after the lapse of a single gear change delay time DEL2, a gear change necessary time from gear change determination becomes substantially the same as a gear change necessary time at the simultaneous gear change, also becomes substantially the same irrespective of a single gear change or a simultaneous gear change of a gear change necessary time after a gear change requirement of a driver up to an inertia phase start at a manual gear change mode, and thus the incongruity imparted to the driver caused by the difference of the gear change necessary times can be suppressed.SELECTED DRAWING: Figure 10
