Abstract
An apparatus comprising a sensor for sensing a signal indicative of vehicle travel, a reset button, a display, a computer controller coupled to the sensor, the reset button and the display, the computer controller including a memory, an input device for receiving the sensed signal, program control for updating and storing trip distance traveled responsive to the received signal, an input device for receiving a reset signal from the reset switch and program control for retroactively resetting the trip distance traveled to a value equal to distance travelled since a last vehicle ignition on responsive to the reset signal; and an output device for controlling the display to display the trip distance traveled.

3. A method of maintaining and indicating vehicle travel data comprising the steps of:
-
receiving a signal indicative of vehicle travel distance; responsive to the received signal, updating and determining a trip travel distance; receiving a signal from a reset button; and responsive to the signal received from the reset button, retroactively resetting the trip travel distance to a distance travelled since a previous point in time; and displaying the trip travel distance. - View Dependent Claims (4, 5)

6. A method of displaying information on a trip computer comprising the steps of:
-
responsive to a depression of a reset button and wherein the depression is for a depression time period less than a first time threshold, maintaining a present display of trip distance; responsive to the depression of the reset button and wherein the depression time period is greater than the first time threshold but less than a second time threshold that is greater than the first time threshold, resetting the present display of trip distance to zero; and responsive to the depression of the reset button and wherein the depression time period is greater than the second time threshold, retroactively resetting the present display of trip distance to a distance traveled since a previous point in time.
