  • Patent number: 9487191
    Abstract: The brake control device applied to a hydraulic pressure braking force generating device having a driving hydraulic pressure generating device and a pilot hydraulic pressure generating device. The brake control device includes a judging portion which judges whether or not an operating amount of a brake operating member is equal to or less than a predetermined value and a pilot hydraulic pressure control portion which controls the pilot hydraulic pressure generating device to generate a preparatory hydraulic pressure in the pilot hydraulic pressure chamber which is larger than an atmospheric pressure set to a value so that a hydraulic pressure in the wheel cylinder is kept substantially to an atmospheric pressure level when the judging portion judges that the operating amount of the brake operating member is equal to or less than the predetermined value to suppress occurrence of brake dragging during non-braking operation with keeping the braking force responsiveness.

  • Patent number: 9381899
    Abstract: An apparatus and method for protecting an intact portion of a service brake system from a failed wheel end of a vehicle is provided. A failure in a wheel end is detected by determining an operation state of each of the wheel ends by monitoring parameters including the pressure in a parking brake air supply line. When it is determined that a failed wheel end is present in the service brake system, an antilock braking modulator or a service brake isolation valve is switched to a state in which the failed wheel end is isolated from the rest of the brake system. The service brake of the failed wheel end is disabled, while the service brakes of the other wheel ends are enabled for normal operation including antilock braking. And the parking brake of the failed wheel end is enabled, while the parking brakes of the other wheel ends are disabled to prevent immobilization of the vehicle.
