  • Patent number: 6429613
    Abstract: A generation control device of a hybrid electric vehicle is able to satisfactorily generate power with an excellent responsiveness with respect to a high output requirement from a motor. If a charge level SOC sensed by a charge level sensing device is not greater than a generation start value SOCsta, a generator starts a normal output generation (P(G)=P1). The normal output generation is continued until the charge level SOC reaches a generation end value SOCend larger than the generation start value SOCsta. If a required power consumption Pm of a traction motor sensed by a required power consumption sensing device is not less than Ph, a high output generation (P(G)=P2) with a higher output than the normal output generation is executed instead of the normal output generation.

  • Patent number: 6318487
    Abstract: A regeneration control device of a hybrid electric vehicle can sufficiently charge a battery with power regenerated as a result of the regenerative braking and effectively perform the regenerative braking, and which can also ease the burden of a friction brake. If chargeable power set by a chargeable power setting device according to an actual level of the battery becomes lower than regenerated power computed by a regenerated power computing unit during the regenerating operation of a motor, the power regenerated by the motor is supplied to a generator. This drives the generator to cause an engine to run an engine brake without the supply of fuel.

  • Publication number: 20010013702
    Abstract: The invention provides a warm-up control device of a hybrid electric vehicle, which warms up an engine for generator while extending the life of the engine and improves the quietness. If an engine temperature is not greater than a set temperature after the start of the engine for generator, the warm-up control device controls a load of the generator and controls an engine output in accordance with the load of the generator so as to maintain an engine revolution speed at a predetermined low revolution speed.

  • Patent number: 5349370
    Abstract: In a signal processing circuit for a pointing device comprising first, second, third, and fourth pressure detection elements corresponding to the movement of a cursor in an X-axis plus direction, an X-axis minus direction, a Y-axis plus direction, and a Y-axis minus direction, respectively, a first processing circuit processes a first pressure detection signal from the first pressure detection element to produce a first move signal representative of a cursor moving value in the X-axis plus direction. A second processing circuit processes a second pressure detection signal from the second pressure detection element to produce a second move signal representative of a cursor moving value in the X-axis minus direction. A third processing circuit processes a third pressure detection signal from the third pressure detection element to produce a third move signal representative of a cursor moving value in the Y-axis plus direction.

  • Patent number: 5349263
    Abstract: A pointing device for use in moving a cursor displayed on a display, includes a pressure sensing sheet including first through fourth pressure detection elements and a base member mounted on the pressure sensing sheet. The base member is provided with first through fourth protrusions formed on its under surface opposite to the pressure sensing sheet in facing relation to the first through fourth pressure detection elements, respectively. The base member is provided with an operation shaft formed on an upper surface of the base member which projects upwardly therefrom. The device further comprises a cap member coupled to the operation shaft of the base member.
