    Abstract: PURPOSE:To raise the responsiveness of a device, by raising the pulse rate when the timing is delayed, in the system which controlls the timing through varying the phase-difference between a driving shaft and a cam shaft by a step motor. CONSTITUTION:Slits which cross with each other, are formed in an outer sleeve which is driven by an engine and an inner sleeve which is connected to a cam shaft, respectively. The valve timing is controlled through moving a slider in these slits by a step motor. Whether the number of steps is increased in order to advance the timing, or the number of steps is decreased in order to delay the timing, is decided by a discriminative means 5 based on output signals from an intake air quantity sensor 2 and an engine speed sensor 3. Then, in case of delaying the timing pulse is fed to the step motor 4 at high pulse rate from a driving means 6. IN case of a small motor load, the motor 4 is rotated at high pulse rate, so a rapid response can be got.

    Abstract: PURPOSE:To prevent hunting by allowing each standard value of the number of revolution and the load in case when the valve timing is switched to be provided with hysteresis characteristic. CONSTITUTION:Since the output-side potential of an operation amplifier 66 is added into the standard level of said amplifier 66 by a feedback resistance R3, the standard level is varied in each case where the number of revolution which is input from a revolution number sensor 64 is increased or reduced, and the number of revolution in each case of switching the valve timing from Low to High or from High to Low is made different. As for the load, a load sensor 69 is operated through a load delay valve, and the load in each case of switching is made different similarly. By such hysteresis characteristic, hunting is prevented, and the torque variation is suppressed, and the comfortable drivability is secured.

    Abstract: PROBLEM TO BE SOLVED: To suitably control valve timing of an internal combustion engine.SOLUTION: An engine 11 includes a variable valve timing control device 18 which transmits rotational force generated by supply of electric power to a motor 26 via a motor drive circuit 31 to the side of a camshaft 16, and thereby changes rotational phases of the camshaft 16 relative to a crankshaft 12. An ECU 30 cools a motor device (the motor 26 and motor drive circuit 31) when stop or almost stop of the change of the rotational phase (locked state) during the changing of the rotational phase of the camshaft 16 to a target value is detected after the engine 11 is at a stop. The motor drive circuit 31 drives the motor 26 after the motor device is cooled to eliminate the locked state.
