Abstract: PROBLEM TO BE SOLVED: To output driving force from a generator to a drive shaft by stably operating an internal combustion engine at a target rotation speed and using reaction force on an engine side. SOLUTION: In an automobile wherein the internal combustion engine, the generator and the drive shaft are connected through a planetary gear mechanism and an electric motor is connected to the drive shaft, when the electric motor becomes a state impossible to drive, a basic throttle opening degree is set based on a differential between the target rotation speed and a present rotation speed of the engine by a relational expression in feedback control, a compensation opening degree for canceling a variation of torque acting on the engine side by a variation of negative torque from the generator is set based on torque acting on the engine side from the generator and on present and previous values of rotation speed of the engine and the target throttle opening degree is set by a sum of both the opening degrees. Quick response can be made to the negative torque variation of the generator at the time of outputting positive torque to the drive shaft by outputting the negative torque from the generator with use of the reaction force of the engine and the engine can be stably operated at the target rotation speed.

Abstract: PROBLEM TO BE SOLVED: To suppress frequent start and stop of an internal combustion engine during a cold state in a power output device provided with the internal combustion engine capable of intermittently operate. SOLUTION: When power output from an engine is greater than set demand power due to high air density during cold state, engine speed is increased by a motor with throttle opening TH held to make power output from the engine agree with demand power (in embodiment, change from point A to point B). Consequently, battery charge by power larger than assumed power is suppressed and frequent stop and start of the engine caused by large fluctuation of battery remaining capacity (SOC) is suppressed.

Abstract: PROBLEM TO BE SOLVED: To suppress the speed change shock at the time of switching the speed change stage of a transmission. SOLUTION: In an automobile where the first motor, to the sun gear of a planetary gear mechanism, an engine, to a carrier, and a drive shaft, to a ring gear, are attached respectively, and the second motor is attached via a transmission to the drive shaft, this device switches (S120-S170) the speed change stage after changing a motor operation mode into an engine/motor operation mode, if positive torque (driving force) is requested for the drive shaft when a request for speed change of the transmission is made amid the running in the motor operation mode. Since it can make the magnitude of the torque to be outputted from a motor MG2 smaller than that in the motor operation mode, by making the directly transmitted torque from the engine act upon the drive shaft in the engine/motor operation mode, it can suppress the speed change torque at switching of the speed change stage.

Abstract: PROBLEM TO BE SOLVED: To further improve acceleration performance when accelerating a vehicle, by releasing only a brake pedal from a state of stepping both an accelerator pedal and the brake pedal. SOLUTION: When both the accelerator pedal 83 and the brake pedal 85 are stepped in stopping, engine request power to be outputted from an engine 22 is set by the sum of an absolute value of input restriction Win of a battery 50 and a Loss. Among operation points capable of outputting the preset engine request power, an operation point of an engine speed higher than an engine speed in an intersection between the engine request power and an operation line for fuel economy, is set as an operation point for taking preference of acceleration over the fuel economy, to control the engine 22. Since a travel resistance quantity by rotational inertial weight of the engine 22 can be reduced in acceleration when releasing the brake pedal 85 thereafter by holding the engine 22 in a high engine speed, the acceleration performance can be further improved.

Abstract: PROBLEM TO BE SOLVED: To make the control simple even when there are a plurality of elements which should be prepared for starting up an internal combustion engine. SOLUTION: A delay time Tset in a normal state is set to a predetermined time Ts1 based on an engine coolant temperature Tw and a state of an air conditioner switch. The predetermined time Tsl is determined based on a time necessary for completing preheating of an engine 22 by a preheating device, preparations of sensors such as an air/fuel ratio sensor, and warming-up of an exhaust gas clean-up device (S100, S110). When it is determined that the vehicle can run using a motor based on a required torque Td*, a required power P* and the remaining capacity (SOC) of a battery (S120 to S150); the engine is started after the delay time Tset has elapsed. As a result, it is possible to efficiently perform start of the engine and operation immediately after the engine starts, and to make control at the time of starting the engine simple compared with the case where the engine is started after making determinations as to whether various preparations have been completed.

Abstract: PROBLEM TO BE SOLVED: To solve a problem that it may be impossible to effectively collect warm water in a heat storage system for an internal combustion engine.
SOLUTION: When an ECU refers to a hysteresis of an accelerator opening, and determines that the accelerator opening (S10a) is small, it is supposed that a peak value and a mean value in the temperature of cooling water for the internal combustion engine are low, and lowers a warm water collection starting temperature from an initial value (S12). When it is supposed that the accelerator opening is in an average (S10b), a collection starting temperature is left to be the initial value (S14) as it is. When it is supposed that the acceleration opening is great (S10c), a warm water collection starting temperature is raised from the initial value (S16).

Abstract: PROBLEM TO BE SOLVED: To prevent lowering of heater performance during stopping of an internal combustion engine, in a vehicle such as a hybrid automobile wherein the internal combustion engine is temporary stopped.
SOLUTION: If a heater is in operation (Y of S10), ECU determines whether the internal combustion engine stops (S12). When the internal combustion engine is stopped (Y of S12), the ECU confirms that the temperature of cooling water is not less than a specified value (Y of S14), and compares the temperature of the cooling water with the temperature of hot water in a thermal storage tank. When the temperature of the hot water in the thermal storage tank is higher than that of the cooling water (Y of S16), the ECU controls a three-way switching valve to supply the hot water in the thermal storage tank to the heater (S18).
