摘要： The invention relates to a system and method for detecting a closing of a solenoid. The system includes a capacitive charge circuit electrically coupled to the solenoid. The capacitive charge circuit conditions the current flow through the solenoid to increase the current in response to the closing of the solenoid. The invention also relates to a system and method that includes detecting a current through the solenoid and determining a current slope characteristic. The current slope characteristic is a function of the current and time. The method also includes conditioning an electrical characteristic of the solenoid such that the conditioning is in response to a current slope parameter. The current slope parameter defines a change in the current after removal of an electrical charge to the solenoid.

摘要： In a vehicle fuel-injection system, additional voltage is applied to an otherwise current-controlled valve solenoid so as to increase the time window over which freewheeling current in the solenoid decreases from a pull-in level to a hold level. The time during which the Beginning of Injection Pulse (BIP) signal is detected is thereby increased.
