  • Patent number: 8116958
    Abstract: The present invention provides a system and method for controlling a driving force of a hybrid electric vehicle which can reduce clutch engagement shock generated during transition from an electric operation mode to an internal combustion engine running mode. For this purpose, the present invention provides a driving force control system of a hybrid electric vehicle including an engine, a motor-generator and a clutch, in which at least one starter-generator directly connected to the engine. The output torques of the engine and the starter-generator are controlled so as to make a difference between the rotational speed of the engine and the rotational speed of the motor-generator reach a predetermined threshold value, and the clutch is engaged when the difference between the rotational speeds reach the value.

  • Patent number: 7786886
    Abstract: A display system for a steering wheel includes: a vehicle information acquiring unit for acquiring vehicle information; an irradiation unit mounted to the steering column such that the irradiation unit is stationary during rotation of the steering wheel; a display device mounted to the steering wheel; and a display controller for controlling display content based on the vehicle information. A method includes: acquiring vehicle information; detecting a steering direction and/or a steering amount of the steering wheel; calculating a display range and/or a display speed to be displayed based on the steering information; controlling display content, based on information acquired by the vehicle information acquiring unit and a result calculated by the display portion calculating unit; and displaying the steering direction, the steering amount, and/or the steering time at a position on the steering wheel that is stationary during rotation of the steering wheel.
