  • Patent number: 8502656
    Abstract: A displacement diagnosis sensor of a brake pedal having a stop lamp switch function is provided. According to the present invention, one sensor performs both a function of a stop lamp switch and a function of diagnosing a rotational displacement of the brake pedal simultaneously to thereby save a manufacturing cost and reduce a weight.
    Type: Grant

  • Patent number: 7750258
    Abstract: A pedal device for adjusting pedal effort includes a housing fixed to a car body, a pedal arm that is hinged about the housing, an elastic member that is disposed between the housing and the pivot end of the pedal arm and provides a return force to the pedal arm, a pedal effort adjusting unit that is movably disposed in the housing and has a sloped portion for adjusting a pre-compression force to the elastic member, and a pre-compression force setting unit that sets a fixed position of the pedal effort adjusting unit with respect to the housing and keeps a pre-compression force applied to the elastic member at a predetermined level. With this configuration, the pedal device can adjust the reaction force applied to the driver pressing the pedal corresponding to the driver's driving propensity, thereby improving the operability and reducing the fatigue of the driver's ankle.

  • Publication number: 20080283372
    Abstract: An object of the present invention is to provide a pedal device that makes it possible to adjust the reaction force applied to the driver pressing the pedal to correspond to the driver's driving propensity by adjusting the pre-compression force against the return spring providing the return force to the pedal arm such that the operability is improved and the fatigue of the driver's ankle is reduced, and corresponds to the requirements of the driver by appropriately adjusting the reaction force.
