  • Rotating electrical machine control system and vehicle drive system
    Patent number: 8125169
    Abstract: A rotating electrical machine control system includes a frequency converting portion that is interposed between a rotating electrical machine for driving a vehicle and a DC power source for supplying electric power to the rotating electrical machine, and that converts an output of the DC power source to an AC output at least during powering operation of the rotating electrical machine; a voltage converting portion that is interposed between the DC power source and the frequency converting portion, and that boosts the output of the DC power source based on a boost command value which is set according to a target torque and a rotational speed of the rotating electrical machine; and a control portion for controlling the frequency converting portion and the voltage converting portion.
    Type: Grant
    Filed: July 1, 2009
    Date of Patent: February 28, 2012
    Assignee: Aisin AW Co., Ltd.
    Inventors: Daisuke Ogino, Takashi Yoshida, Subrata Saha, Jin Izawa, Norio Tomiya

  • Vehicle drive control apparatus, vehicle drive control method and program therefor
    Patent number: 6968260
    Abstract: A vehicle drive control apparatus includes buffers, as a recording portion, set for each of a plurality of storage items, each of the plurality of storage items having a different sampling cycle, and a controller that samples variable quantities, that indicate a status of a vehicle that changes with a running of the vehicle, at a sampling cycle set for each of the plurality of storage items and records the variable quantities in each of the buffers as storage data.
