摘要： A power drive control device is provided, in which, even if drive of a synchronous motor becomes impossible due to abnormalities of a control circuit for controlling the synchronous motor, it is possible to perform the drive control of the synchronous motor concerned easily with a simple configuration as emergency action. Failure of one of a first controller and a second controller is recovered by configuration of the other. Here, the first controller performs rotational drive control and regenerative control of a synchronous motor, based on a current signal of a fixed winding of the synchronous motor and a sense output from a rotation angle sensor of the synchronous motor, and the second controller performs power generation control of a synchronous generator based on a current signal of a fixed winding of the synchronous generator and a sense output from a rotation angle sensor of the synchronous generator. The drive control and the regenerative control (power generation control) which are performed by the first controller for controlling the synchronous motor and the second controller for controlling the synchronous generator are inextricably linked control.

摘要： A fuel injection control apparatus for an internal combustion engine is provided. A controller directs a fuel injector to spray a learning injection quantity of fuel and determines a resulting increase in speed of the engine. The controller determines the quantity of the fuel actually sprayed from the fuel injector based on the increase in speed of the engine and calculates a correction factor which compensates for a difference between the learning injection quantity and the actual injection quantity. The controller also determines a variation in load acting on a driving member of a torque transmission mechanism. When such a variation is great undesirably, the controller stops spraying the learning injection quantity. The controller may determine the increase in speed of the engine based on the degree of the variation in load. This ensures the accuracy in calculating the correction factor regardless of the variation in load.

摘要： A fuel injection controller calculates a difference between a rotation speed fluctuation amount of an engine in the case where an injection for learning is performed and the rotation speed fluctuation amount in the case where the injection for the learning is not performed as a rotation speed increase amount. The controller calculates an actual injection amount actually injected from an injector based on a rotation state of the engine. The controller calculates a difference between the actual injection amount and a command injection amount outputted to the injector as a characteristic deviation and corrects the command injection amount to reduce the characteristic deviation. The controller prohibits the correction of the command injection amount when a variation in the rotation speed increase amount is equal to or greater than a specified value.

摘要： If a user presses a clutch pedal to perform gear-shifting operation while a vehicle is traveling, a clutch disc, which has been engaged with a flywheel rotating with an engine, is brought to partial clutch engagement and slides on an end surface of the flywheel to generate friction. Thus, a first phenomenon in which a decreasing rate of the engine rotation speed rapidly increases occurs. Then, a second phenomenon in which the clutch disc is completely disengaged from the flywheel to eliminate the friction and the decreasing rate of the engine rotation speed returns to an original state occurs. If the first and second phenomena are detected successively when neither an engine side nor a power transmission system side transmits power for varying an engine rotation speed, it is determined that the clutch disc is disengaged.

摘要： An electronic control unit (ECU) of an injection control system of an internal combustion engine measures an engine rotation speed in a period from a time point when an exhaust valve opens to a time point when a top dead center of a next cylinder is detected after a single injection is performed. The ECU calculates a rotation speed fluctuation caused by the single injection based on the engine rotation speed. The engine rotation speed provided immediately after the single injection is measured after a cylinder pressure increased by the single injection decreases to substantially the same level as the cylinder pressure provided in the case where the single injection is not performed. Therefore, the rotation speed fluctuation corresponding to torque generated by the single injection can be measured accurately.

摘要： A fuel injection control device of a diesel engine performs a learning injection during a no-injection period, in which a command injection quantity is zero or under. A difference between a variation in the engine rotation speed in the case where the learning injection is performed and a variation in the engine rotation speed in the case where the learning injection is not performed is calculated as a rotation speed increase. A torque proportional quantity is calculated by multiplying the rotation speed increase by the engine rotation speed at the time when the learning injection is performed. An injection correction value is calculated from a deviation between the actual injection quantity, which is estimated from the torque proportional quantity, and the command injection quantity. The command injection quantity is corrected based on the injection correction value.

摘要： An electronic control unit (ECU) of an engine calculates a first modification value for decreasing a correction value of an injection period when a state variation of the engine caused by a single injection is greater than a target value. The ECU calculates a second modification value for increasing the correction value when the state variation is less than the target value. The second modification value is greater than the first modification value. Thus, a period necessary to converge the correction value can be shortened when the correction value is increased. The first modification value is increased if a difference between the state variation and the target value exceeds a permissible value when the correction value is decreased. Thus, the injection quantity is decreased quickly to prevent excessive fuel injection.
