METHOD AND APPARATUS FOR CONTROLLING FUEL RAIL PRESSURE USING FUEL PRESSURE SENSOR ERROR |
摘要 |
A control system and method for controlling a fuel system of an engine includes a steady state determination module determining the engine is operating at a steady state and a memory storing a first fuel correction. A fuel pump control module commands a predetermined fuel rail pressure change. The memory stores a second fuel correction after the predetermined fuel rail pressure change. A sensor error correction module determines a fuel rail pressure sensor error based on the first fuel correction and the second fuel correction and determines a fuel rail pressure in response to the sensor error.
