    摘要： A fault sensing device for a vehicle includes a time measuring section functioning as a sleep mode while power to a controller is off. The time measuring section can measure a stop time of an engine, and can transmit information on the stop time to the controller when power to the controller is on. When the controller determines that a stop time of the engine is a predetermined time, the controller performs fault sensing for an oil pressure switch.

    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： A stroke detection apparatus performs a stroke detection of 4-cycle engine based on a rotary engine speed when a throttle opening is large. A first crank-pulse time interval between a crank pulse inputted before a top dead center by 30°, and a crank pulse of the top dead center is measured by a pulse-interval calculation unit, and at the same time, a second crank-pulse time interval between a crank pulse inputted after the top dead center by 60° and a crank pulse inputted after the top dead center 90° is measured. An interval difference calculation unit calculates time-interval difference by subtracting the second crank-pulse time interval from the first crank-pulse time interval, for two continuous top dead centers. A stroke detection unit determines whether two top dead centers are a compression top dead center or an exhaust top dead center based on magnitudes of the time-interval differences.

    摘要： A shift controller for a motor vehicle includes an electric motor configured to rotate a shift drum associated with a transmission. An oil temperature sensor is configured to detect temperature of lubricating oil for the transmission. A controller is configured to control the electric motor. The controller controls the electric motor to operate in a preset first motor duty until a first predetermined time elapses after operation of the electric motor is started when the shift drum is turned from a first predetermined position to a second predetermined position. The controller is also configured to operate the electric motor in a second motor duty calculated based upon oil temperature after the first predetermined time elapses.

    摘要： The present invention provides an intake air amount control apparatus for an engine and a control method of an intake air amount of an engine, in which, when the atmospheric pressure exceeds a threshold value, a target lift amount of an intake valve is determined based on a target intake air amount and an electronically controlled throttle is controlled to generate a target boost pressure. On the other hand, when the atmospheric pressure does not exceed the threshold value because of a vehicle traveling at a high altitude, the target lift amount of the intake valve is fixed to a maximum lift amount and the opening angle of the electronically controlled throttle is determined in response to the target intake air amount. Consequently, an actual intake air amount is controlled to be brought to the target intake air amount thereby generating negative pressure necessary for exhaust gas recirculation.
