摘要： A failure detection apparatus for preventing erroneous detection due to a degradation of a sensor and thereby accurately performing failure detection of a variable valve timing and lift control system is provided. The detection apparatus detects a failure of a variable valve timing and lift control system in an engine. The detection apparatus detects a vibration inside an engine cylinder, extracts the component of seating sound of the valve from the output signal of the sensor, determines an actual seating time of said valve from the component of seating sound, and calculates a target seating time of said valve based on at least one of a requested lift amount, a requested advance angle, and a requested open angle depending on the operating conditions. The detecting apparatus corrects the actual seating time for a stationary deviation between the actual seating time and the target seating time caused by degradation or unevenness of the sensor. The detecting apparatus determines a failure of the variable valve timing and lift control system by comparing the corrected actual seating time with the target seating time.

摘要： A method and system for providing data representing crankshaft position. For each rising edge of the crankshaft signal, a position value and a factor value are stored in a look-up table. Cam and crankshaft signals are used to locate an initial crankshaft position. This initial position value is used as a pointer to the look-up table, and incremented with each rising pulse of the crankshaft signal. Data from the table is used to extrapolate crankshaft position from crankshaft signal values to a desired resolution in degree angle units.

摘要： If, when a valve lift adjustment is triggered in an inlet valve of an internal combustion engine, no valve lift adjustment actually takes place due to a defect in the adjustment mechanism, the air/fuel ratio (lambda) or even a different operating parameter for example the engine speed and torque changes in an unintended manner. By monitoring this operating parameter the operation control device can deduce a defect in the adjustment mechanism.

摘要： To provide a control device capable of calculating a cam phase equal to an actual cam angle even when a corresponding cam angle signal detection range is exceeded by changing a cam phase by a variable valve mechanism. In addition to the conventional cam angle measuring function, a cam angle measuring means for advancing or retarding beyond a cam angle measurement reference position, and a means for determining that the cam angle signal advances or retards beyond the cam angle measurement reference position are provided. By switching the cam angle measuring function according to a determination result as to whether the cam angle signal exceeds the cam angle measurement reference position, it is possible to improve the time resolution of the angle measurement while maintaining the cam phase change amount at the same wide angle as the conventional one.

摘要： A valve opening and closing timing control device includes a driving-side rotating body, a driven-side rotating body, a stopper configured to determine a mechanical limit of a displacement region of a relative rotation phase, a phase control mechanism configured to change the relative rotation phase, and a control unit configured to control the electric motor so as to displace the actual phase detected by a phase sensor. A limit phase at which the stopper reaches an abutting state is set in advance when rotation of the electric motor is stopped while the internal combustion engine operates. Upon executing stop control of stopping the internal combustion engine, except when the actual phase is already the limit phase, the control unit executes braking control of limiting the rotation of the electric motor by controlling an electric current to be supplied to the electric motor.

摘要： A continuously variable valve duration (CVVD) system includes an electronic control unit (ECU) configured to output a command for adjusting an actuator and a controller configured to determine a operation range of a control shaft of the actuator and adjust the control shaft in the determined operation range based on the command of the ECU. The controller positions the control shaft at a predetermined target phase and determines a control state of each target phase based on a target phase value transmitted from the actuator when the control shaft is positioned at the target phase.

摘要： A drive circuit (203) of an actuator (2) calculates an actual working angle from an actual operation quantity with reference to a reference table used to calculate a target operation quantity, and transmits the actual working angle and the actual operation quantity to a command unit (4). The command unit (4) determines whether or not the received values of the actual working angle and the operation quantity correspond to the valve working angle and the operation quantity of the reference table stored in the command unit (4), to detect a discrepancy between the operation modes of the actuator (2) and the command unit (4).

摘要： A control device has two modes as control modes of an electric power supply to an electromagnetic solenoid, which are used when a first determining unit determines that a difference between a sensed value of a phase and a target value of the phase exceeds a permissible range. One of the modes is a special mode that is used when a second determining unit determines that the sensed value of the phase reaches a threshold value. Another one of the modes is a normal mode that is used when the second determining unit determines that the sensed value of the phase does not reach the threshold value. In the special mode, the control device controls supply of the electric power to the electromagnetic solenoid in such a manner that an opening degree of an advancing port is larger than the opening degree of the advancing port in the normal mode.
