ABSTRACT:
According to the present invention, there is provided a method and system for providing brake control, autobrake and antiskid brake functionality by recognizing that the only difference between the three functions is the amount of deceleration they allow. Unlike a conventional system where the pedals represent brake pressure, the present invention interprets pedal commands as desired deceleration. The method and system involve controlling acceleration of a wheel reference speed and setting a desired slip based on autobrake settings, pedal positions, and various parameters. A proportional/integral/derivative algorithm controls wheel speed and is monitored for normal operation. Abnormal operation generates control parameters which are used to alter the wheel reference speed and its deceleration. Additionally, vehicles using the invention will benefit from improved yaw stability, even brake temperatures and differential braking during antiskid operation.
