PROBLEM TO BE SOLVED: To provide an injection amount measurement device and method, capable of performing proper signal processing related to an injection amount of fuel, in interruption for sampling at high speed.SOLUTION: An injection amount measurement device 10 generates interruption in each predetermined time (for example, 5 micro seconds); regards each generated interruption as one state; performs processing different in each state, the processing containing processing of inputting a signal, processing of performing FIR (Finite Impulse Response) calculation for each channel, and processing of performing differential calculation for calculating an injection rate of fuel; makes signal processing of one cycle by processing of combining processing of plural states; and performs processing of measuring a fuel injection amount on the basis of the signal processing.SELECTED DRAWING: Figure 1 |
