ABSTRACT:
In a remaining fuel amount measuring apparatus, a CPU captures remaining fuel amount data detected by a fuel sender unit at prescribed periods through a voltage conversion circuit and A/D conversion circuit, compiles the captured remaining fuel amount data into blocks each composed of a prescribed number of data samples to be successively stored in a RAM. The CPU reads the block data as necessary and subjects the read data to data processing such as simple averaging, weighted averaging or removal of abnormal values. The CPU displays the remaining fuel amount after the data processing on a fuel meter.
