摘要： PROBLEM TO BE SOLVED: To provide a battery power distribution control device capable of smoothly performing the start of an engine by restricting the drive of an auxiliary unit in accordance with the residual capacity of power in the power supply of a vehicle. SOLUTION: The SOC, voltage, temperature, etc., of a battery are fed to a limit value calculation part 30, and the allowable battery output or battery voltage is grasped as the residual capacity of power of the battery. In accordance with the allowable battery output or battery voltage, the limit value calculation part 30 calculates the limit value of an oil pump motor 22, and the obtained value is fed to an oil pump motor control part 28. The oil pump motor control part 28 limits the torque or revolving speed of the oil pump motor 22 in accordance with the limit value. This allows securing the power supplied to a cranking motor 10, which allows the engine 12 to be started smoothly.

摘要： PROBLEM TO BE SOLVED: To improve detecting accuracy of misfire by certainly avoiding mis- detection of misfire of an internal combustion engine in a hybrid vehicle. SOLUTION: An operation state of a motor of the hybrid vehicle is detected, and a driving condition of the vehicle is detected. The motor is connected to an axle, so that the driving condition of the vehicle can be accurately detected. Based on the detected driving condition, whether or not the hybrid vehicle is driven is discriminated under a predetermined mis-detection assuming condition that may satisfy a miss detection condition of the misfire of the internal combustion engine. When the driving under the mis-detection assuming condition is determined, a misfire detecting process is suppressed or stopped. Thus, the condition that may cause mis-detection of the misfire is detected, and the misfire detecting process is suppressed or stopped before satisfying of the misfire condition, thereby certainly avoiding mis-detection of the misfire. When the mis- detection of the misfire can be certainly avoided, detection sensitivity of the misfire can be improved and slight misfire can be accurately detected.

摘要： PROBLEM TO BE SOLVED: To improve reliability of idling control in the case where rotating speed of an internal combustion engine is controlled by the idling control and control requirement other than the idling control in the internal combustion engine. SOLUTION: When an acceleration operation in terminal at a time t0, fuel injection is cut, and rotating speed of an engine 150 is reducing-controlled by a motor MG1. When rotating speed of the engine 150 attains a prescribed value (1500 rpm) (at a time t1) while rotation of the engine 150 is controlled by the motor MG1, an ISC calculation demand is outputted. A changing process is performed to gradually reduce an engine target rotating speed calculation value t-ntcal (Step 330), and its changing process result is set to an engine target rotating speed entcal (Step 320). A deviation (an effective deviation ΔH) for calculating a valve opening is gradually reduced comparing with a case where the gradual change processing is not performed, and thereby, excessive valve closing driving is avoided.

摘要： PROBLEM TO BE SOLVED: To reduce the generation of NOx and vibration when restarting an engine. SOLUTION: In automatically stopping the engine, the rotational phase of an intake side camshaft is changed to the maximum delay angle (S3), and fuel cut-off is executed after completing the change to the maximum delay angle, (S6) to stop the rotation of the engine. The combustion of the engine is thereby continued even during the change of the rotational phase to suppress the generation of NOx at the restart caused by an oxygen storage effect due to the decrease of the oxygen supply quantity to a catalyst provided in an exhaust pipe. Prior to restarting the engine (S13), a crankshaft is rotated twice in a normal direction (S12) to rotate the intake side and exhaust side camshafts respectively by one round. The intake side camshaft is thereby positioned on the most delay side, and air in all the cylinders is changed to reduce rotational resistance caused by pressure in the cylinders. Engine speed is thereby increased rapidly passing through a resonance area when starting.

摘要： PROBLEM TO BE SOLVED: To provide a rotation speed control device for an internal combustion engine favorably controlling the rotation speed, even if performing a feedback control of the rotation speed of the internal combustion engine in a condition directly connected to a driving wheel. SOLUTION: In a driving system of a hybrid vehicle, a crankshaft 10a of the internal combustion engine 10 is directly connected to the driving wheel 15 via a power division mechanism 13. An ECU 16 performs the feedback control of the rotation speed by regulating the throttle opening using a feedback correction term eqi calculated according to a deviation between the actual rotation speed ene and the target rotation speed entcal of the internal combustion engine 10. Wherein the ECU 16 finds feedback correction terms eqi1-eqi3 for every three operation regions divided according to the car speed so as to control the rotation speed using the feedback correction term in the operation region corresponding to the car speed at that time.

摘要： PROBLEM TO BE SOLVED: To provide an engine speed control system for a hybrid vehicle capable of preventing deterioration of drivability without effect of a battery condition and preventing restriction of battery use even if gasoline of low octane number. SOLUTION: This system compensates torque reduction from knocking control by controlling a generator 11 with an inverter to increase speed or driving force of an electric motor 12 according to a torque reduction amount TQlo. Torque reduction thereby can be compensated without changing output force of an engine 10 or a load on a battery 42. Engine output therefore can be provided as desired without effect of a condition of the battery 42 such as remaining capacity and temperature of the battery 42.

摘要： PROBLEM TO BE SOLVED: To prevent the generation of an unnatural behavior of a vehicle and generation of an excessive load applied to a power transmitting system, when fuel is used up in an internal combustion engine, in the vehicle provided with an internal combustion engine and a rotating electric machine. SOLUTION: A residual amount of fuel stored in a fuel tank 36 is detected by a fuel sensor 38. When the residual amount of the fuel is decreased to a prescribed value or smaller, a control part 34 sets limits to a charge performed by the rotating electric machine 14 for front wheels. In this way, the torque generated by the charge prevents a vehicle from rapidly decelerating. The control part 34 inhibits the power running control of the rotating electric machine 16 for rear wheels. In this way, when the fuel runs short, the direction of torque is set opposed to each other by applying a brake force to the front wheels and a drive force to the rear wheels, the vehicle is prevented from generating the unnatural behavior and generating a rapid torque change in the power transmitting system.

摘要： PROBLEM TO BE SOLVED: To prevent the generation of a wheel hitting sound in a gear mechanism in the prime mover stopping time, without reducing the efficiency as a power output device. SOLUTION: When an ignition switch 179 is turned off and an engine 150 is stopped, in a hybrid vehicle with an engine being operated in the stopping condition, the throttle valve 166 of the engine 150 is fully closed, or the valve overlapping is reduced by an opening and closing timing conversion mechanism 153, so as to increase the pumping work of the engine 150, and a load is connected to one shaft of a planetary gear 120. As a result, the load to reduce the rotation frequency is to be applied continuously to one shaft of the planetary gear 120, and the wheel hitting sound by the speed difference between the wheels of the planetary gear 120 is suppressed, so as to reduce the wheel hitting sound.
