摘要： Method for estimating the position and the speed of an actuator body in an electromagnetic actuator for controlling a valve of an engine, according to which, starting from a known value for the position and a first moment, a value is calculated at the first moment of the magnetic flux passing through a magnetic circuit constituted by an electromagnet and by the actuator body, the value for the speed at the first moment is estimated as a function of the magnetic flux and the position at the first moment, and the value is calculated at a second moment following the first moment and separated from said first moment by an interval of time determined by adding to the value of the position at the first moment the product of the speed at the first moment for the interval of time.

摘要： An engine has cylinders, a fuel injection unit with a valve operable in response to a valve control signal to cause fuel to be injected into the cylinders, and a control unit which generates the valve control signal. A method of controlling the valve includes sensing a time associated with movement of the valve corresponding to start of a fuel injection event, and modifying the valve control signal as a function of the sensed time. The method further includes determining a rise time of the valve control signal, determining a valve operation delay time as a function of the rise time, determining a difference time representing a difference between a desired valve operation time and the sensed time, comparing the valve operation delay time to the difference time, and adjusting timing of the valve control signal as a function of the comparison. The method, also, as a function of the comparison, varies individual valve control signal parameter values, each associated with a particular cylinder of the engine, generates a sum value SUM representing a sum of the individual parameter values for all the cylinders, generates an average parameter AVE by dividing the SUM value by the number of cylinders, generates updated individual parameter values by subtracting the AVE value from previous individual parameter values, and modifies the valve control signal as a function of the updated individual parameter values.

摘要： A switch monitoring system for measuring closure time of a switch in a vehicle when the vehicle ignition switch is off. The switch monitoring system includes an application specific integrated circuit, a low powered stand-by voltage source, and external interface circuitry connected to the switch, The switch monitoring system uses very little current to operate the time base and switches off completely after switch closure has been captured, thus preventing excessive battery drain. The microprocessor software can obtain the time to closure at the next vehicle power-up sequence.

摘要： A second operation mode without a hold period is used for starting up an engine when the ambient temperature is extremely low so that an electromagnetic coil remains fed with the current until the valve opening is completed, thus ensuring elimination of an injection valve cling up. A full opening of the injection valve is recognized by detecting a decrease of a coil current in the electromagnetic coil. The lower the temperature where the cling up is hardly eliminated in a short period, the longer the energizing period for the coil is provided. Consequently, such an event as failing to eliminate the cling up due to too short of the energizing period will be prevented.
