    Abstract: PROBLEM TO BE SOLVED: To enable an internal combustion engine right after start to stably operate at idling speed. SOLUTION: A learning error Er is calculated by subtracting a sum of a friction torque base value Tb estimated from cooling water temperature THW of the engine at the time and friction torque learning collection value Gf which is precious value (Tc-Tb) under a temperature condition roughly same as cooling water temperature THW from cranking torqye Tc at a time of start of the engine(S106), water temperature learning flow rate Qthw as temperature dependent flow rate depending on cooling water temperature THW in idling rotation retaining flow rate Qisc is renewed (S112-S120) by the learning error Er, and ISCV opening is adjusted by adding the water temperature learning floe rate Qthw to a target idling rotation retaining quantity Qisc* (S122-S126). Consequently, a device can appropriately cope with a case that friction varies right after start of the engine with depending on type of filled lubricating oil, the engine can be stabilized at idling speed.

    Abstract: PROBLEM TO BE SOLVED: To make effective use of the regenerative power of a motor and enhance the energy efficiency of an entire vehicle in an automobile provided with the motor capable of generating power by power from an axle. SOLUTION: The automobile is provided with the motor MG2 connected with driving wheels 39a and 39b. When the regenerative power of the motor MG2 exceeds a limit value on the power with which a battery 50 can be charged, the excess power is consumed at an electric heater 66 and is stored as heat in a heat accumulation tank 65. When a request is made to start an engine 22, the setting of a three-way valve 68 is changed so that the heat exchange medium in the heat accumulation tank 65 is supplied to the engine 22 until the engine water temperature becomes equal to or higher than a predetermined temperature. Thus, the regenerative power of the motor MG2 can be utilized without wastage as required, and the energy efficiency of the vehicle can be further enhanced. COPYRIGHT: (C)2005,JPO&NCIPI

    Abstract: PROBLEM TO BE SOLVED: To perform continuity of exhaust gas for HC desorption to an HC adsorbing material layer when starting an engine in an engine warming-up state. SOLUTION: This device is provided with an exhaust system including an HC adsorbing material layer and an exhaust gas purifying catalyst layer having an oxygen holding function. By passing the exhaust gas through the HC adsorbing material layer when starting a cold temperature of the engine, the HC absorbing material layer is made to adsorb HC in the exhaust gas. By passing exhaust gas through the HC adsorbing material layer after warming-up of the engine and the exhaust system, HC adsorbed by the HC adsorbing material layer is desorbed. An HC eliminating operation for the engine exhaust device for a wheel for discharging the desorbed HC by being converted into H2O and CO2 by oxygen held in the exhaust gas purifying catalyst layer is ensured and generation of NOx is suppressed by the exhaust gas purifying catalyst layer when starting the engine after warming-up of the engine.

    Abstract: PROBLEM TO BE SOLVED: To further improve an atmospheric environment conservation characteristic by suppressing exhaustion of hazardous gas components following temporary stop and restart of an engine in an economy running car or a hybrid car. SOLUTION: A vehicle has an exhaust purifying catalyst having a function for reserving oxygen in an exhaust system of an internal combustion engine, temporarily stops the engine when a predetermined temporary stop condition of the engine is satisfied, and temporarily increases fuel for reduction treatment of the exhaust purifying catalyst in restarting the engine. When the reserved oxygen amount of the exhaust purifying catalyst in restarting the engine is not estimated to be within a predetermined range in a fuel cut-off operation, a fuel increasing operation, or the like, fuel increase in the reduction treatment of the catalyst is inaccurate and hazardous gas components may be exhausted in restarting the engine, so that the temporary stop of the engine is prohibited.
