摘要： When a request for re-start of an engine or a request for start occurs during inertial revolution of the engine by fuel cut at the time of request for idle stop, an operation of starting by re-start of fuel injection and an operation of driving the starter overlap, and a problem is likely to occur in wear resistance and durability of a ring gear and a pinion gear. Further, since collision torque becomes large, a collision sound of the ring gear and the pinion gear and a mesh sound which occurs at the instant of connection are likely to occur. The present invention changes a method of starter drive based on a behavior of engine revolution after a request for re-start of the engine or a request for start occurs during inertial revolution of the engine by fuel cut at the time of request for idle stop, and combustion recovery is implemented by an engine combustion recovery function, or an engine state or the like at the time of occurrence of change of mind, in a controller of a vehicle having an idle stop function.

摘要： When cranking starts by turning on a starter switch 14, the ignition timing is first corrected to a fixed value on a retard side. When an IACV 6 reaches a fully opened position, the ignition timing is corrected to the retard side once, and thereafter corrected to an advance side. The correction to the advance side is performed in accordance with a difference between the number of idling target steps and the current number of steps, and the amount of advance correction is reduced as the difference is reduced. Upon completion of the initialization of the IACV 6, the ignition timing correction amount is then restored to the initial value by increasing the amount of advance by a predetermined amount in a stepwise manner.

摘要： Embodiments of the invention provide that an ignition is retarded when continuously occurring knocks are detected, while an ignition is not retarded when a singly occurring knock is detected.By detecting the number of occurrences of detection data pieces from a knock sensor 9 stored in a storage unit 14 in a predetermined time period, a distribution of the detection data pieces is created. When one detection data piece having a value not less than a knock determination value is inputted from the knock sensor 9, the distribution of the detection data pieces is checked. For example, when the detection data pieces spread in a wide range, or the knock level voltage of the total detection data pieces is not less than a predetermined value, a retard instruction is outputted.

摘要： An electronic throttle control system and method are provided. The system includes a throttle valve, a motor configured to drive the throttle valve, and a throttle position sensor configured to detect an angle of the throttle valve. The system further includes an engine rotating speed detector, and a controller. The controller is configured to drive the motor to control the angle of the throttle valve. The controller is configured to initially set a lower limit value of the angle to an angle which is greater than a full closure angle of the throttle valve by a predetermined amount. The controller is further configured to, when a rise in an engine rotating speed is detected, re-set the lower limit value to reduce it by a predetermined amount to control the engine rotating speed to within a predetermined value from the preset idle speed.

摘要： An engine rotational speed display device includes a rotational speed sensor and a pulse rotor. An engine rotational speed calculating unit is configured to calculate an engine rotational speed by a moving average of a detected value of a crankshaft rotational speed pulse. A display unit is configured to display the engine rotational speed on a meter by electrical processing. When the crankshaft rotational speed pulse is not detected in a detection time equal to or more than a predetermined value, the engine rotational speed calculating unit determines that the engine rotational speed is “0,” and the engine rotational speed of “0” is displayed on the meter.

摘要： An engine control apparatus includes a control unit configured to perform a feedback control based on a second amount of intake air until a engine speed reaches a target idle speed. The engine control apparatus then regulates the amount of intake air to an amount smaller than a predetermined second amount of intake air for a predetermined period when the engine speed exceeds the target idle speed, and then performs a feedback control based on a first amount of intake air. Such engine control apparatus minimizes variation in engine speed by reducing a convergence time of the engine speed to a target idle speed in switching control of the amount of intake air in a case where engine friction at a low temperature is high.
