Gear shift control device of vehicle

A gear shift control device of a vehicle including an engine and a motor installed as driving sources, and an automatic transmission provided between the driving sources and drive wheels, the automatic transmission performing a gear shift by switching between high and low gear positions through hydraulic control, the gear shift control device comprising:

• memory storing a gear shift map that defines, for each of a plurality of gear shift points, thresholds of a number of revolutions on a downshift side and on an upshift side to determine a switching start timing of each of the gear positions;
• a transmission control unit that switches between the high and low gear positions based on the gear shift map;
• and
• a regeneration control unit that controls regeneration by the motor,
• wherein the gear shift map includes a cooperative regeneration map used in cooperative regeneration that cooperates with a brake, and a non-cooperative regeneration map used in other than cooperative regeneration, the non-cooperative regeneration map defining the thresholds of revolutions lower than the thresholds in the cooperative regeneration map, and
• wherein the non-cooperative regeneration map includes a first map that defines the thresholds of relatively low revolutions and is used when an accelerator is not used, and a second map that defines the thresholds of relatively higher revolutions and is used when the accelerator is used.
