    Abstract: PROBLEM TO BE SOLVED: To improve fuel consumption of a hybrid vehicle during an EV travel. SOLUTION: A speed control method for a hybrid vehicle is provided. The hybrid vehicle comprises a diesel engine, a multi-mode transmission, a clutch for connecting or disconnecting the power transmission between the diesel engine and the multi-mode transmission, and a motor generator for assisting power generation by an engine output or an engine output by a battery power. The hybrid vehicle can be driven only by either one of the diesel engine or the motor generator. During the EV travel driven only by the motor generator, a gear position of the multi-mode transmission is controlled into a neutral position (step S10 yes, step S11). COPYRIGHT: (C)2005,JPO&NCIPI

    Abstract: PROBLEM TO BE SOLVED: To provide an operation environment comfortable for a user, by reducing the number of occurrence of vibrations or the like caused by shift between two kinds of power sources or changing shifts in a transmission, in a power output device provided with two kinds of the power sources and the transmission. SOLUTION: The power output device comprises: the transmission connected or disconnected to an engine through a clutch; a driving shaft to which rotating power is transmitted through the transmission; and a motor connected to the transmission to drive the driving shaft. The driving shaft is driven by a first mode or second mode where the driving shaft is driven by the engine or motor, and by a third mode where the driving shaft is driven by the engine and motor. A control means controls the engine, motor, and transmission so as to perform transmission operation in the transmission simultaneously with at least one mode shift operation out of shift operations among the first mode, second mode, and third mode.

    Abstract: PROBLEM TO BE SOLVED: To provide a traveling support device capable of suppressing deterioration of a fuel consumption rate by vehicle speed fluctuation and maintaining an optimum fuel consumption rate.
    SOLUTION: In this traveling support device 1, optimum traveling speed to produce the optimum fuel consumption rate is displayed on a display part 16 when it is decided that a traveling state of one's own vehicle is a steady traveling state. A driver therefore drives the vehicle, independently of the optimum traveling speed, in cases other than the steady state. As a result, braking operations by the driver due to adjusting to the optimum speed are reduced and speed fluctuation caused by an increase of the number of times of speed reduction is suppressed, to prevent deterioration of fuel consumption. In this way, the fuel consumption rate is improved by displaying the optimum traveling speed to produce the optimum fuel consumption rate in the steady traveling state, the deterioration of the fuel consumption rate is prevented since the optimum traveling speed is not displayed in traveling states except the steady traveling state, and thereby the optimum fuel consumption rate can be maintained.

    Abstract: PROBLEM TO BE SOLVED: To provide a vehicle control technique capable of suppressing operation of an internal combustion engine in an operation state with a high fuel consumption rate even when a vehicle start cornering during acceleration and coasting travel.
    SOLUTION: An HVECU 100 makes a vehicle 1 perform acceleration and coasting travel by repeating acceleration travel in which an internal combustion engine 10 is brought into an operation state to drive the vehicle 1 by driving force and coasting travel in which the engine 10 is brought into an non-operation state to drive the vehicle 1 by coasting force between preset upper and lower limit vehicle speeds. When determining that the vehicle 1 is cornering during acceleration travel, the HVECU 100 stops the acceleration travel, lowers the driving force in comparison to the case where the acceleration travel is not stopped in the cornering, and also makes a motor MG1 operate as a power generator to convert kinetic energy by the lowering of the driving force into charging electric power.

    Abstract: PROBLEM TO BE SOLVED: To provide a power output device suppressing vibration caused by engagement of a clutch while supplying hydraulic pressure necessary for the engagement to the clutch. SOLUTION: This power output device 3 has: a motor 50 and an internal combustion engine 5 as motors; and first and second transmission mechanisms 30, 40 changing a speed of mechanical power from transmission mechanisms thereof. The second transmission mechanism 40 receives the mechanical power from a rotor 52 and an engine output shaft 8 by a second input shaft 28. The second clutch 22 is enabled by receiving the hydraulic pressure of minimum operating pressure. An oil pump 90 supplies the hydraulic pressure generated according to a rotor rotational speed of the motor 50 to the second clutch 22. An ECU 100 increases the rotor rotational speed such that the hydraulic pressure detected by a hydraulic pressure sensor 96 becomes the minimum operating pressure or above, and thereafter reduces the rotor rotational speed as compared to the rotor rotational speed when reaching the minimum operating pressure to engage the second clutch 22.
