PURPOSE:To control speed surely and easily, by displaying a target speed pattern of vehicles by prescribing the distance from a reference point and the speed by two axes of a display and displaying the real traveling speed on the display in cross-reference to said pattern. CONSTITUTION:Preset speed of a vehicle and a traveling distance from station A are detected by a speed detection circuit 3 and a traveling distance detection circuit 4 from an output of an electric dynamo 1 in proportion to the speed of the vehicle. Further, said detected value is operated by a CPU2 putting together with various data stored in a memory circuit 6 and mutual relation is displayed on the face of a board of a display 9 through a bus line 8 and a display interface circuit 7. |
