发明名称 Fuel Control for Direct Injection Fuel System
摘要 A method for controlling a direct injection fuel system of a vehicle, the method comprising generating fuel pressure via an electronically controlled lift pump and a second pump, the electronically controlled lift pump actuated responsive to a command during an initial start-up duration, translating the fuel pump command via a first mapping to drive the fuel pump, where the first mapping includes mapping a default signal to active pump operation and after the initial start-up duration, translating the fuel pump command via a second mapping to drive the fuel pump where the second mapping includes mapping the default signal to pump deactivation. This method may achieve near immediate lift pump actuation upon system power-up while preserving favorable degradation modes and maintaining a simple, cost-effective inter-module communication scheme.
