Abstract
An efficiency gauge from a vehicle information display may incorporate vehicle range information in addition to an efficiency indicator. The range information may be displayed as an area on the efficiency gauge indicating a safe operating region for average driving in order for the vehicle to reach a target destination entered by a driver before an on-board energy source is depleted. By maintaining a vehicle'"'"'s average trip efficiency within the safe operating region through driving behavior, the display may convey that the vehicle will be able to make it to the target destination. Over the course of a trip, the safe operating region may be constantly updated to reflect the current state of the battery and the remaining distance to the target destination. If no target information is received, a default target distance value based on an initial distance to empty estimation may be used.

21. An information display system comprising:
-
an information display including an energy consumption gauge having a threshold and an efficiency indicator; and a controller in communication with the information display and configured to; receive a target distance, calculate a threshold value associated with the threshold based upon a battery state and the target distance, calculate an efficiency value associated with the efficiency indicator, and transmit signals causing the information display to adjust the threshold based on the threshold value and the efficiency indicator based upon the efficiency value. - View Dependent Claims (22, 23, 24, 25, 26, 27, 28)
