    Abstract: PROBLEM TO BE SOLVED: To efficiently charge a battery while suppressing the discharge of smoke in a diesel hybrid vehicle. SOLUTION: In case that the amount of battery charge SOC drops under a specified tolerance (positive in step S10), a stepped automatic transmission is shifted down from its stationary travelling at a maximum gear change stage to a low-speed stage which is lower by one stage (S11), and then even in case that it enters a shift up region to a maximum gear change stage by reacceleration, the shift up to the maximum gear change stage is inhibited (positive in step S12 and step S13), and the high-rotation operation of a diesel engine is executed to activate a motor-generator as a generator thereby charging the battery. When the battery is charged and the amount of charge SOC reaches a specified tolerance or over (negative in step S10), the speed is changed according to a usual schedule (step S14).

    Abstract: PROBLEM TO BE SOLVED: To suppress the shortage of torque assistance to a request for acceleration even if the charged amount of a battery lowers to a specified value or below. SOLUTION: This hybrid vehicle 10 comprises an engine 11, a step type transmission 12, a motor generator 17, an electric supercharging system formed of a motor-assisted turbo-supercharger, an assist amount calculation means calculating a torque assist amount based on a deviation between a driver requesting torque and an actual engine torque, a charged amount detection means detecting the charged amount SOC of a battery 20, and a torque assist control means assisting the torque assist amount calculated by the assist amount calculation means by using one or both of a motor generator 17 and the electric supercharging system according to the detected charged amount SOC. When the charged amount SOC is small, torque assist is performed by the electric supercharging system, and when the charged amount SOC is large, the torque assist is performed by a motor generator.

    Abstract: PROBLEM TO BE SOLVED: To provide a method for reducing toothing noise of a drive system gear device of a hybrid vehicle, in which the toothing noise of the drive system gear device is reduced by controlling a motor generator. SOLUTION: If a toothing noise occurs with the drive system gear device provided to a motor generator 17, the motor generator 17 is controlled to be put in powering side to suppress the output of an diesel engine 11 when a battery 20 has a sufficient remaining capacity. The motor generator 17 is controlled to be put in regenerative side to raise the output of the diesel engine 11 when the battery 20 has not sufficient remaining capacity. These controls are performed in a prescribed range of revolutions where the toothing noise occurs. COPYRIGHT: (C)2005,JPO&NCIPI

    Abstract: PROBLEM TO BE SOLVED: To avoid to make a driver uncomfortable or uneasy by preventing a wheel, connected to a drive shaft in assist, from slipping when assisting by the other drive source is carried out as one power is not transmitted to the drive shaft, in a hybrid vehicle comprising two kinds of drive sources. SOLUTION: The hybrid vehicle is provided with an engine, a motor, a transmission which is connected to or disconnected from an engine through a clutch, a front wheel to which the power outputted from the engine is transmitted through the transmission, and a rear wheel to which a second power outputted from the motor is transmitted. A control means is provided where a torque rate limit value TRM and a torque output limit value TM are provided according to the level of a road surface transmission drive force which the front wheel and the rear wheel receive (or, the level of friction factor of a road surface on which they contact), during gear shifting operation on the transmission, and which changes the output of a motor (see R1 in figure) according to a limit value.
