A gear shift control device of an automobile including a driving motor, a relay clutch capable of disconnecting an engine, includes memory storing a gear shift map for determining the switching start timing of the gear position, a transmission control unit that switches the gear position based on the gear shift map, a regeneration control unit, and a relay clutch control unit. The gear shift map includes a cooperative regeneration map and non-cooperative regeneration maps that define the thresholds of relatively low revolutions. The threshold of a predetermined low gear shift point is defined to be smaller than the thresholds of the gear shift points higher than the predetermined low gear shift point on the downshift side in the non-cooperative regeneration maps, and is defined to be smaller than the threshold of the predetermined low gear shift point on the downshift side in the cooperative regeneration map.

Gear shift control device of vehicle

A gear shift control device of an automobile includes memory storing a gear shift map that defines, for each of gear shift points, thresholds of the number of revolutions to determine a switching start timing of each of the gear positions, a transmission control unit that performs switching between the gear positions based on the gear shift map, and a regeneration control unit that controls regeneration. The gear shift map includes a non-cooperative regeneration map that defines the thresholds of revolutions lower than the thresholds in a cooperative request map used in cooperative regeneration, and the non-cooperative regeneration map includes a combustion request map that defines the thresholds of low revolutions and is used when an accelerator is not used, and a travel request map that defines the thresholds of relatively higher revolutions and is used when the accelerator is used.

A shift control system for an automatic transmission is provided. The system includes a shift switch through which a manual transmission command for arbitrarily changing a gear stage of the automatic transmission can be inputted in a manual transmission mode. The manual transmission mode includes a first manual mode in which the gear stage is changed and maintained by inputting the manual transmission command using the shift switch, and a second manual mode in which an automatic transmission mode is resumed by satisfying a resuming condition after the gear stage is changed. The system includes a mode input device configured to select in advance one of the first manual mode and the second manual mode to be set, the mode input device setting to the automatic transmission mode by the selected mode being changed from the first manual mode to the second manual mode, or vice versa.

Shift control system for automatic transmission

A shift control system for an automatic transmission is provided, which is mounted on a vehicle configured to be started by an ignition switch being turned on, where an automatic transmission mode or a manual transmission mode is selectively set. The system includes a shift switch through which a manual transmission command for arbitrarily changing a gear stage of the automatic transmission can be inputted in the manual transmission mode, and a controller. The manual transmission mode includes a first manual mode in which the gear stage is changed and maintained by inputting the manual transmission command using the shift switch, and a second manual mode in which the automatic transmission mode is resumed by satisfying a resuming condition after the gear stage is changed. When the ignition switch is turned on, the controller selects in advance the second mode to be set to the automatic transmission.
