Measurement of gas fuel amount

摘要

A control unit 40 acquires acceleration alpha sensed by an acceleration sensor 31, and if the control unit 40 determines that acceleration alpha does not equal zero, the control unit 40 again acquires acceleration alpha. In the event that the control unit 40 decides that acceleration alpha equals zero, the control unit 40 acquires the weight M sensed by the weight sensor 30. The control unit 40 continues sampling of weight M until a predetermined sampling period has elapsed. Once the sampling period has elapsed, the control unit 40 calculates the average of weight M obtained through sampling, and uses the calculated average and a map to determine hydrogen amount.
