Abstract: PROBLEM TO BE SOLVED: To provide a control device of a hybrid vehicle, which enables charging to be conducted by operating an engine in a fuel-efficient operating range, when charging is required during traveling in torque amplifying mode. SOLUTION: When it is decided during the traveling of the vehicle that charging is required in the torque amplifying mode, an engine control means 108 makes the output torque of the engine 14 increased up to a value TEC during a request for the charging, and a part of the output torque of the engine 14 makes a starter motor generator(SMG) 70 generate electricity. Accordingly, since the output torque of the engine 14 is partially consumed by making the SMG 70 generate the electricity, without increasing speed NE of revolution of the engine 14, the charging can be performed, without making the speed NE increase so much; and the charging can be performed by operating the engine 14 in the fuel-efficient low-engine-speed high-torque operating range, when the charging is required during the traveling in the torque amplifying mode.

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 reduce shock during the transient period when a load operation state for generation changes into a no-load operation state including idling or motoring in a hybrid vehicle. SOLUTION: With regard to a hybrid power outputting device comprising an engine and a generator connected mechanically, the output torque of the generator is controlled so that it may not change suddenly during the transient period when the load operation state shifts to the no-load operation state. As a means, the minimum revolutions of an internal combustion engine under the load operation state is set to the revolutions by about 200 rpm larger than those under the no-load operation state. This setting makes the revolutions of the engine change smoothly during the period from the load operation state to the no-load operation state. Because the sudden change of torque of the generator under the PI-control based on the revolutions of the engine can be suppressed, the shock to be caused by the sudden change of torque can be reduced.

Abstract: PROBLEM TO BE SOLVED: To improve drivability of a vehicle by reducing unnatural feeling and unpleasant feeling imparted to a driver by start/stop of an engine when the vehicle is driven. SOLUTION: In a stop/start control device for engine adapted in a vehicle in which an engine is stopped when a prescribed stop condition is formed and the engine is started when a prescribed starting condition is formed also when a shift position is a traveling position, the shift position of the vehicle is detected and the engine starting condition is changed to a side for making the engine difficult to be started when the shift portion is the traveling position. By this constitution, engine starting speed at the time of the traveling position is rationally distributed to a non-traveling position time side.
