  • Publication number: 20240092337
    Abstract: A vehicle control apparatus includes front-wheel and rear-wheel driving systems, and a control system. The front-wheel driving system includes a first travel motor mechanically coupled to a front wheel of a vehicle and a first accumulator electrically coupled to the first travel motor. The rear-wheel driving system includes a second travel motor mechanically coupled to a rear wheel of the vehicle and a second accumulator electrically coupled to the second travel motor. The control system includes one or more processors and one or more memories communicably coupled to the one or more processors, and controls the first and second travel motors. When a difference between an SOC of the first accumulator and an SOC of the second accumulator is greater than a threshold value, the one or more processors change a torque distribution ratio between the first and second travel motors from a reference distribution ratio.

  • Patent number: 6848449
    Abstract: A smoking article is manufactured through supplying a tobacco filler material onto a tobacco wrapping paper sheet that is transferred, wrapping the tobacco filler material supplied onto the tobacco wrapping paper sheet with the tobacco wrapping paper sheet so as to prepare a rod body, and cutting the rod body into a plurality of tobacco rods each having a prescribed length. The tobacco filler material contains at least 20% by weight of expanded tobacco material. The tobacco wrapping paper sheet is coated with the burn adjusting agent during transfer of the tobacco wrapping paper sheet.
