Zusammenfassung:	PROBLEM TO BE SOLVED: To reduce detection error of fuel pressure in a common rail and to suppress occurrence of inconvenience caused by the detection error occurred. SOLUTION: Two common rail pressure sensors 16, 17 are provided in the common rail 12 and detection signal of the sensors 16, 17 is acquired by ECU 20 respectively. The ECU 20 averages pressure detection value based on the detection signal, and offsets the averaged results in a range of sensor individual body characteristic dispersion. Common rail pressure is calculated based on pressure detection value after the offset. COPYRIGHT: (C)2007,JPO&INPIT
