    摘要: A hybrid vehicle is provided with an engine (2), a first motor (1) for starting the engine (2), a generator (1) for driving the engine (2), drive wheels (8) connected to the engine (2) via a clutch (3), and a second motor (4) for driving the drive wheels (8). A battery (15) connected to the first motor (1), second motor (4) and generator (1) is further provided. A control device which controls the engine startup by the first motor (1) comprises a sensor (27) which detects a rotation speed of the engine (2), a sensor (26) which detects the charge amount of the battery (15), a power controller (11) which varies the current supplied to the first motor (1) from the battery (15) according to a signal, and a microprocessor (16) which outputs the signal. The microprocessor (16) calculates a target output torque of the first motor (1) according to the charge amount of the battery (15). When the rotation speed of the engine (2) is less than a predetermined target rotation speed, the signal is set so that the output torque of the first motor (1) coincides with a predetermined output torque, and after the rotation speed of the engine (2) reaches the predetermined target rotation speed, the signal is set so that the rotation speed of the engine (2) is maintained at the predetermined target rotation speed.

    摘要: This invention relates to a valve timing control device for a vehicle engine (2) which performs combustion stop in a predetermined vehicle running condition. The predetermined vehicle running condition comprises, for example, engine startup, and combustion stop is performed by stopping fuel supply to the engine (2) or stopping ignition of the supplied fuel. The device comprises an actuator (51A, 52, 55, 61) which varies the timing of an intake valve of the engine (2) according to an input signal, and a microprocessor (16, 31) which outputs the signal to the actuator (51A, 52, 55, 61). The microprocessor (16, 31) is programmed to determine whether or not combustion has stopped (S80), and when combustion has stopped, control the signal so that the open/close timing of the intake valve is retarded compared to the case when combustion has not stopped (S94).

    摘要: The present invention is proposed to avoid the generation of shocks when the output of an engine is switched with that of an electric motor connected by a clutch. The invention comprises a first electric motor connected mechanically to an engine and a second electrical motor connected mechanically through a clutch to an engine. The drive force is transmitted to the drive wheel through a transmission from the second electric motor. It is decided whether or not to connect the clutch on the basis of driving conditions. When it is decided to connect the clutch, the engine is controlled so that the output of the engine meets the required force. The first electric motor functions as an electric generator so that the rotation speed of the engine reaches a target rotation speed. When the engine is rotating at a target rotation speed, the clutch is connected. In this way, shocks are avoided when the clutch is connected and improved driving performance is realized.
