A method for controlling brakes may comprise receiving, by a controller, a yaw rate from an inertial sensor, calculating, by the controller, a force correction, calculating, by the controller, a pressure correction, and adjusting, by the controller, a pressure command for a brake control device.

This electric braking device for a vehicle imparts to the wheels of the vehicle a braking torque in accordance with the output of an electric motor. A vehicle body-side electronic control unit calculates a command value for the output of the electric motor on the basis of the amount of operation performed on a braking operation member. A wheel-side electronic control unit adjusts the output of the electric motor on the basis of the command value. The vehicle body-side electronic control unit calculates the vehicle body speed on the basis of the wheel speed. The wheel-side electronic control unit adjusts the output of the electric motor so as to prevent an increase in slippage of the wheels on the basis of the vehicle body speed and the wheel speed.

A system and method of adjusting a vehicle anti-lock brake or collision mitigation system includes multiple tire-based sensors mounted to a vehicle tire to generate tire-derivative information. An adaptive tire model processes the tire-derivative information to continuously generate in real-time revisions to multiple tire-specific performance parameters affecting the performance of a vehicle control system. The vehicle control system receives and applies in real-time the tire-sensor based revisions to the tire-specific performance parameters optimize control system performance.

An electric brake for a wheel rotor having a brake pad includes a housing with a passage. A piston assembly in the passage includes a spindle and a piston. The spindle is rotatable to cause the piston to move axially relative to the brake pad. A drive assembly includes a motor. A gear train is connected to the motor and the spindle. A coupling mechanism is coupled to the gear train and has a first condition enabling torque transmission from the motor to the spindle to axially move the piston to apply braking force to the brake pad. The coupling mechanism has a second condition disabling torque transmission from the motor to the spindle is prevented which permits the piston to retract and reduce the braking force on the brake pad without stopping or reversing the motor.
