摘要： Acceleration detecting sensor (60) is provided in a sprung structure (50), while a vibration model comprising the sprung mass of a vehicle, the spring, and the shock absorber is previously stored in control unit (58). The deviation of the detected acceleration from the estimated vertical acceleration of the sprung structure is computed by a control unit (58) and then amplified. The vertical acceleration of the sprung structure and the relative velocity between sprung and unsprung structures are estimated by a control unit (58) according to the amplified deviation and the vibration model. The stored vibration model has one degree of freedom and a simple structure.

摘要： It is determined that a periodic zero current stagnation state is reached to correct a voltage command of a smoothing capacitor downward by a predetermined voltage when a state where a current (reactor current) flowing through a coil in a dead time when switching elements are both off immediately after the switching element (upper arm) is turned off from on stagnates at a value of 0 occurs at switching periods of the switching elements. This can prevent a voltage of the smoothing capacitor from becoming unexpectedly higher than the voltage command in the current stagnation state, prevent the smoothing capacitor from being damaged by an overvoltage and prevent excessive torque from being output from motors.

摘要： Two inverters (INV1, INV2) supply phase currents to three-phase coils (Y1, Y2). Although two phase currents must conventionally be measured and four current sensors are thus required, according to the present invention, the number of phase currents to be measured is reduced as a result of use of an observer for phase current estimation.

摘要： An idle speed control apparatus for an internal combustion engine is provided which, when the internal combustion engine is started in a cold mode, provides ignition timing engine speed control (m1) such that ignition timing in which said ignition driving device performs ignition in the internal combustion engine is retarded and the engine speed of the internal combustion engine is controlled to the target engine speed, and then provides intake air quantity engine speed control (m2) such that the engine speed of the internal combustion engine is feedback-controlled to the target engine speed by controlling the intake air quantity of the internal combustion engine. As a result, it is possible to prevent the exhaust gas temperature from being increased insufficiently due to a deficiency in retard angle, and to prevent the activation of a catalytic converter from being delayed.
