Fuel quantity display device
First Claim
1. A fuel quantity display device comprising:
- engine start detection means for detecting an engine start;
fuel quantity detection means for detecting a quantity of a remaining fuel in a fuel tank; and
fuel quantity display means for displaying the remaining fuel quantity on the basis of the quantity detected by the fuel quantity detection means, wherein the remaining fuel quantity is detected by the fuel quantity detection means after the detection of the engine start by the engine start detection means.

Abstract
A meter microcomputer provided in the fuel quantity display device is connected to a battery through an ignition switch. The meter microcomputer obtains an ON/OFF signal for an accessory terminal and an ignition terminal so as to detect an engine start based on the result. Thereafter, the meter microcomputer compares the remaining fuel quantity detected by fuel quantity detection devices and the remaining fuel quantity stored immediately before the previous turn-OFF operation of the ignition terminal. Based on the result of comparison, the meter microcomputer determines whether the fuel is fed or not. In addition, the meter microcomputer determines a gradient based on an estimated gradient value detected by an AT control microcomputer, and calculates a value indicating the remaining fuel quantity, based on the result of determination for fueling and the determination result of a gradient so as to display it on the display meter.
