    摘要: An injector driver fault detect and protection device for use with fuel injection systems that include at least one solenoid (17) for controlling a fuel injection valve, control means for providing a control signal, injector driver means (14) responsive to the control signal for providing a drive signal, and a current control switch (16) being responsive to the drive signal for selectively closing and opening a power line that includes the solenoid (17) to thereby control the fuel injection valve. The device includes a fault detect and protection unit that receives current sense information regarding the flow of current through the solenoid (17), control signals from the control unit (13), and engine rotation data in the form of CAM degrees from a CAM position sense unit (19). Based upon this information, the fault detect and protection unit (11) can provide a fault protect signal to a fault control switch (12) to open circuit the solenoid (17) under specific fault conditions, and to provide a fault data signal under other fault conditions, as appropriate.
