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： A motor rotation angle detection device includes a resolver which detects a rotation angle of a motor generating an assist torque for steering road wheels. The resolver includes an annular rotor disposed inside an annular stator with an air gap interposed in between an outer circumferential surface of the rotor and an inner circumferential surface of the stator, so that the stator and the rotor are rotatable relative to each other. A rotor supporting member is connected to a rotary shaft of the motor, and the rotor extends out from an axial end portion of the rotor supporting member so as to surround an outer periphery of the rotary shaft. With the described motor rotation angle detection device, it is possible to stabilize the magnetic permeability of the rotor, and accordingly to increase an accuracy with which the rotation angle of the motor is detected.

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.
