A shift map switching control unit includes a fuel level sensor 72 , plural shift maps for deriving the shift timing of an automatic transmission 1 b, and a controller 101 that selects one shift map out of the plural shift maps and controls the shift of the automatic transmission 1 b according to the selected shift map. The controller 101 switches a standard shift map 103 to a high fuel economy shift map 104 in which fuel consumption is reduced when it is sensed that the residual quantity of fuel is equal to or below a predetermined value. An operational mode display lamp 99 displays the selected shift map. As the residual quantity of fuel is sensed, based upon a mean value of output signals from the fuel level sensor 72 in predetermined time, the shift maps can be prevented from being frequently switched. |
