  • Publication number: 20210122341
    Abstract: A braking control device of a vehicle in which a braking force generator is connected to a differential mechanism to which a plurality of wheels is connected, and a friction brake is provided for each of the wheels includes a controller configured to control braking forces of the braking force generator and the friction brake. The controller is configured to: detect the wheel having a tendency of locking in which a slip ratio is larger than a predetermined determination value in a state where the braking force is transmitted to each of the wheels from the braking force generator via the differential mechanism; and reduce the tendency of locking by changing the braking force of the friction brake that is provided for the other wheel connected to the differential mechanism.

  • Patent number: 10886084
    Abstract: A pressure switch includes an airtight metallic pressure vessel. A contact mechanism is normally in a closed state and assumes an open state when a pressing force acts thereon. An airtight terminal, provided through an end surface section of the pressure vessel, is connected to the contact mechanism. A metallic first diaphragm is secured to a surface section at one end of the pressure vessel, is moved by a first moving pressure, and is reset by a reset pressure that is lower than the first moving pressure. A first plunger causes the contact mechanism to switch the open state. A metallic second diaphragm is secured to pressure vessel, is moved by a second moving pressure that is higher than the first moving pressure, and is not reset under at least an atmospheric pressure. A second plunger causes the contact mechanism to switch to the open state.
