PURPOSE:To secure good shift feeling by providing a shift shock judging means, a shift time judging means, and an accumulator pressure correction quantity learning means correcting an accumulator based on the length of the shift time when a shift shock occurs. CONSTITUTION:For shift control, a vehicle speed V is D/A-converted, acceleration alpha is calculated by differentiating the vehicle speed V, the peak value alphap of acceleration and target acceleration alphad are compared, and it is judged that a shift shock occurs if alphap>alphad. The shift time is judged by comparing the shift time Ts until the shift shock occurs after the shift start and the target shift time Td. If Ts<Td at a quick shift, the accumulator pressure is decreased by the correction quantity - P, the engagement of a shift clutch 1 is delayed, and the shift shock is corrected to a low shift shock. If Ts<=Td at a slow shift, the pressure of an accumulator 10 is increased by the correction quantity P, the coupling of the clutch 1 is accelerated, and the shock is reduced. |
