Fuel remaining quantity alarming device

Abstract

Abstract PURPOSE:To omit an exclusive sensor, etc. for an alarm, by detecting the storage quantity of fuel analogically, executing its digital-conversion, displaying it on a bar graph gauge, and also outputting the minimum remaining quantity to a deciding part, and issuing an alarm. CONSTITUTION:The storage quantity of a vehicle fuel tank 1 is detected by a float 2, is digitally converted, and a position of the float 2 is calculated by a decoder 6. Subsequently, it is transmitted to a driving circuit 7 provided with a matrix circuit, and is displayed by a bar graph gauge 8 which has generated plural signals. On the other hand, a signal inputted to low-rank display elements 9, 10 is inputted to an OR gate 14, a transistor 16 is operated, and an alarm lamp 18 is turned on. Accordingly, an alarm in case when the remaining quantity of fuel has become very little, and display of the bar graph gauge 8 can be interlocked, and an exclusive sensor for an alarm is not required, therefore, the device can be simplified.
