Abstract

A display system is a display system which is installed in a vehicle and includes a liquid crystal display unit which outputs information representing a deviation amount of the current running speed of the vehicle from a speed limit set for an area where the vehicle is currently running.

Claims

1. A display system installed in a vehicle, comprising:

a display unit for displaying a deviation amount of a current running speed of the vehicle from a speed limit set for an area where the vehicle is currently being driven, wherein

the display unit outputs a value of the deviation amount as a ratio of a speed difference to the speed limit on a scale display in which a point where the ratio is zero is used as an origin, with a scale division indicating a predetermined range of values of the deviation amount, where the speed difference is the speed limit subtracted from the current running speed, and wherein

the display unit has a running speed display area which outputs information representing the current running speed of the vehicle and a deviation amount display area which outputs the deviation amount juxtaposed with the running speed display area.
