To provide a shift map switching control unit that switches a shift map of an automatic transmission to a shift map for reducing fuel consumption according to residual quantity in a fuel tank. A fuel level sensor (72) that senses residual quantity in a fuel tank (71), plural shift maps for deriving the shift timing of an automatic transmission (1b) and a controller (101) that selects one shift map out of the plural shift maps and controls the shift of the automatic transmission (1b) according to the one shift map are provided. The controller (101) switches a standard shift map (103) to a high fuel economy shift map (104) in which fuel consumption s 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) is arranged in a meter init (90) and the selected shift map is displayed. 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. |
