    • The invention relates to a brushless motor drive device that performs switching determination of energization modes of a three-phase brushless motor according to a sensorless method, and a drive method thereof. A pulse induced voltage induced in a non-energized phase of three phases by a pulse voltage is compared with a threshold to determine the switching timing of the energization modes. Here, by limiting a duty ratio of a voltage application to equal to or greater than a lower limit, a situation in which the pulse induced voltage is sampled while the pulse induced voltage is oscillating is avoided, and a situation in which the pulse induced voltage falls below a voltage detection resolution is avoided. As a result, determination of energization mode switching timing based on a pulse induced voltage can be performed more stably.

    • 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.
