Abstract

In-vehicle display apparatus includes a unit for detecting an acceleration of a vehicle and outputting an acceleration detection signal, a display control unit for outputting a display control signal to perform a graphic display of the acceleration of the vehicle in a mode according to the change therein, and a display unit for graphic display. The acceleration information is detected by the acceleration detecting unit as points, and the points are added up at predetermined time intervals. The added-up data as stored in a memory unit so as to display it graphically on the display unit. The in-vehicle device stores multiple pieces of the data added up in the past in the memory unit, and graphically displays them in series on the display unit.
