  • Apparatus and method for advanced anti-skid brake and traction controls
    Patent number: 9796364
    Abstract: A disk brake system includes a magnetically encoded disk brake rotor having at least one magnetized section encoded therein and a disk brake caliper comprising a plurality of disk brake pads attached thereto, the disk brake pads positioned adjacently to the disk brake rotor and configured to frictionally engage the disk brake rotor upon operation of the disk brake caliper. The disk brake system further comprises a sensor assembly mounted proximately to the disk brake rotor and comprising at least one magnetic field sensor configured to detect the at least one magnetic field, and a controller configured to receive signals from the at least one magnetic field sensor. The controller is further configured to enable selective operation of the disk brake caliper based on the signals received from the at least one magnetic field sensor.
