Abstract:
1. A vehicle, comprising: a driving source; a transmission coupled to said driving source and capable of changing a gear ratio by shift; and a control apparatus, wherein said transmission performs the shift by changing a friction engagement element to be in an engaged state, and said control apparatus is configured to: perform damping control by which said driving source is controlled to output torque for reducing up-and-down vibrations of the vehicle, determine whether or not to perform the shift of said transmission, interrupt said damping control when determining to perform the shift of said transmission, predict a time when the output torque of said driving source stabilizes after said damping control is interrupted and magnitude of the output torque of said driving source from when said damping control is interrupted to when the output torque of said driving source stabilizes, control said transmission to delay a start of the shift until the output torque of said driving source stabilizes after said damping control is interrupted, in a case where the output torque of said driving source stabilizes within a predetermined time period after said damping control is interrupted, and control said transmission to delay the start of the shift until said predetermined time period elapses since said damping control is interrupted, and controls engagement force of said friction engagement element during the shift of said transmission in accordance with the predicted magnitude of the output torque of said driving source, in a case where the output torque of said driving source does not stabilize within said predetermined time period after said damping control is interrupted.
