A shift map switching control unit includes a fuel level sensor 72, 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 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.

1. A shift map switching control unit for controlling a shift timing of an automatic transmission of a vehicle, comprising: a plurality of shift maps for deriving the shift timing of the automatic transmission;a fuel sensor that senses a residual quantity of fuel in a fuel tank of the vehicle;a controller for selecting one of said plurality of shift maps for switching control of a shift of the automatic transmission, at least based partly upon an input received from said fuel sensor; anda display for displaying a condition in which the shift map of the high fuel economy type is selected,wherein, when said controller receives an input from said fuel sensor representing the state that a residual quantity of fuel in the fuel tank is equal to or below a predetermined value, said controller selects a shift map of a high fuel economy type in which fuel consumption is reduced,wherein the residual quantity of fuel in the fuel tank is sensed based upon a mean value of output signals from said fuel sensor in a predetermined period of time, andwherein when said controller switches to the shift map of the high fuel economy type, the display is flickered before the shift map switching is initiated. 2. The shift map switching control unit of claim 1, wherein said display includes a first lamp and a second lamp, said first lamp being illuminated when a shift map of a standard fuel economy type is selected and said second lamp being illuminated when the shift map of the high fuel economy type is selected, andwherein when said controller switches to the shift map of the high fuel economy type, the second lamp is flickered before the shift map switching is initiated.
