  • Patent number: 12240493
    Abstract: A vehicle includes a sideslip preventing function of preventing a sideslip of the vehicle by separately adjusting a longitudinal force applied to each of the wheels. A controller controls the vehicle based on requests input from a driver assistance device, thereby causing the vehicle to travel autonomously. The controller calculates wheel lateral force request values based on the requests input from the driver assistance device. The wheel lateral force request values are request values of lateral forces acting on the respective wheels. The controller, when a behavior of the vehicle is in an oversteer state in a case in which the sideslip preventing function is failing, limits the wheel lateral force request values for the front wheels to values less than or equal to a first lateral force limit value, which is a limit value of the lateral force that can act on the rear wheels.

  • Publication number: 20130278100
    Abstract: A wind power generator includes: an input rotor provided so as to be rotatable together with an output shaft of a speed increaser; an output rotor provided so as to be rotatable together with a drive shaft of a generator; and a one-way clutch arranged between the input and output rotors. The one-way clutch connects the input rotor to the output rotor such that the input rotor and the output rotor are rotatable together with each other when a rotation speed of the input rotor exceeds a rotation speed of the output rotor, and that disconnects the input rotor from the output rotor when the rotation speed of the input rotor falls below the rotation speed of the output rotor. The one-way clutch has a rotation speed limiter that disconnects the input rotor from the output rotor when the rotation speed of the output shaft exceeds a predetermined value.

  • Publication number: 20090068049
    Abstract: An oil pump has: a base part having a working chamber; and a rotor provided rotatably in the working chamber. The base part is configured by a plurality of split bodies. At least one of the plurality of split bodies is made of aluminum alloy, and on which an opposed sliding surface made of a ceramic film is formed. The ceramic film of the opposed sliding surface has a hardness of approximately Hv 500 to 1100 and a surface roughness of approximately 2 to 8 micrometers, and contains ?-alumina and zirconia.
