The shift execution portion operates the shift actuator to control the connecting portion in an engaged state engaged with the idler gear of a present gear stage to disengage from the idler gear of the present gear stage while gradually decreasing the engine torque while the clutch is still engaged, when a shift operation from the present gear stage to a subsequent gear stage is executed.

Abstract: A vehicle control apparatus of embodiments includes a regeneration control portion, a judgment portion, a driving control portion and a discharge control portion. The regeneration control portion performs a regeneration control by the motor generator. The judgment portion determines whether or not the regeneration control by the motor generator is under execution and determining whether or not a state quantity of a battery exceeds a predetermined threshold value in a case where the regeneration control is under execution. The driving control portion disconnects between a driving shaft of the vehicle and the motor generator in a case where the regeneration control is under execution and the state quantity of the battery exceeds the predetermined threshold value. The discharge control portion discharges the battery by controlling the motor generator to perform a power operation in a state where the driving shaft and the motor generator are disconnected.
