VEHICLE GEAR-SHIFTING CONTROL APPARATUS, AND VEHICLE
DRIVE
January 29, 2025
A vehicle gear-shifting control apparatus is equipped with an engine, a motor, an automatic transmission, a friction brake system, and a controller which executes, at least during deceleration of an automobile, regeneration control of imparting a regenerative braking torque to rear wheels by causing the motor to perform a regeneration operation and gear-shifting control of changing a shift stage of the automatic transmission in accordance with the rotation speed of an input shaft. The controller starts the gear-shifting control, triggered by the rotation speed of the input shaft dropping to a predetermined shift-down point, and during deceleration of the vehicle when it is determined that a road surface µ is lower than a predetermined threshold in the regeneration control, the controller sets the shift-down point lower than during deceleration of the vehicle when it is determined that the road surface µ is equal to or higher than the threshold.
