摘要： When the variation of the KCS learning value is large, an ISC learning control is performed in a learning acceleration mode in which the amount of the ISC learning update is large and the ISC learning is performed at high speed. By thus performing the ISC learning control in the learning acceleration mode in which the ISC learning is performed at high speed, the ISC learning control can quickly follow up a great variation of the KCS learning value, and the time required for the ISC control value to converge to the most suitable one can be shortened. With this, the ISC learning control performed during idling of a hybrid car can be completed in a short time, and the fuel consumption enhancement effect by idling stop can be heightened.

摘要： In a hybrid vehicle equipped with an engine and a motor that are connected to a driveshaft linked to an axle via a gear mechanism, on condition that a torque demand Tr* required for the driveshaft is lower than a preset reference torque level Tref (step S220) and that a vehicle speed V is lower than a preset reference speed level Vref (step S230), the drive control of the invention idles the engine (step S240) regardless of a stop request of the engine (steps S120 and S210). This arrangement effectively reduces the potential for backlash or gear rattle in the gear mechanism. On condition that the vehicle speed V is not lower than the preset reference speed level Vref (step S220), on the other hand, the drive control of the invention stops the operation of the engine (step S250) in response to the stop request of the engine (steps S120 and S210) even under the torque demand Tr* of lower than the preset reference torque level Tref (step S230). This arrangement desirably enhances the energy efficiency of the hybrid vehicle.

摘要： A hybrid vehicle can be driven using both of respective driving forces from an engine and a motor. A heating mechanism of an air conditioning apparatus uses thermal energy from cooling water of the engine to heat the interior of a passenger compartment. An ECU takes into consideration engine efficiency from the standpoint of fuel economy enhancement to primarily determine the driving force share ratio between the engine and the motor. Further, the ECU calculates a preset temperature corresponding to a cooling water temperature necessary for desired heating as well as a control target temperature in which the preset temperature is reflected, and corrects the primarily determined driving force share ratio to increase the share of the driving force of the engine by an amount according to a deviation between the cooling water temperature measured by a water temperature sensor and the control target temperature. Heating performance can thus be ensured promptly without deterioration of fuel economy.

摘要： In a hybrid vehicle equipped with an engine and a motor that are connected to a driveshaft linked to an axle via a gear mechanism, on condition that an output torque of the motor (previous Tm2*) is not lower than a preset reference output torque Tm2ref (step S190) at a moment of a start requirement of the engine (steps S130 and S180), the drive control of the invention starts the engine (step S220). On conditions that the output torque of the motor (previous Tm2*) is lower than the preset reference output torque Tm2ref (step S190), that a torque demand Tr* is lower than a preset reference torque level Tref (step S200), and that a state of charge SOC of a battery is not lower than a preset reference charge level Sref (step S210), the drive control keeps the engine at a stop (step S140), regardless of the start requirement. This arrangement effectively reduces the potential for backlash or gear rattle in the gear mechanism due to a torque pulsation applied to the driveshaft at a start of the engine.

摘要： When the variation of the knock control system learning value is large, an idle speed learning control is performed in a learning acceleration mode. In this mode, the idle speed learning update increases and idle speed learning is performed at a high speed. By performing the idle speed learning in the learning acceleration mode, the idle speed learning can immediately follow large variations of the knock control system learning value. Accordingly, the idle speed learning control performed during idling of a hybrid car can be completed in a short time, and fuel consumption during idling can be reduced.
