Abstract:
1. A vehicle comprising: an automatic transmission mounted in said vehicle; and a control device programmed to control said automatic transmission, wherein said control device having a plurality of control modes selected in accordance with running conditions of said vehicle, sets a target value of an input shaft revolution speed of said automatic transmission in accordance with the selected control mode, when said control mode is changed in accordance with a change of said running conditions, a constant used for defining the input shaft revolution speed of said automatic transmission during change of the control mode from said target value set in the control mode before change to said target value set in the control mode after change is determined for each of said plurality of control modes, said control device is further programmed to: select a constant determined for a control mode that is higher in predetermined priority among said control mode before change and said control mode after change, when said control mode is changed, set at least one of a time constant of a first-order lag system, an upper limit value of a change rate of said target value and a lower limit value of the change rate of said target value based on a map and said selected constant, and control, based on at least one of said time constant, said upper limit value or said lower limit value that have been set, the input shaft revolution speed of said automatic transmission when said control mode is changed.
