A system for controlling a lateral trajectory of an aircraft includes a rudder bar. Each pedal of the rudder bar is movable between a neutral position (p.sub.n) and an end-of-travel position (p.sub.f) along a unique travel. A movement of the pedal between the neutral position (p.sub.n) and an activation position (p.sub.act) commands a lateral movement by actuating a lateral movement device of a first set including a nose gear wheel, the different braking of the aircraft being nonactive. A movement of the pedal from the activation position (p.sub.act) to the end-of-travel position (p.sub.f) commands a lateral movement by actuating a device of the first set and the differential braking. A haptic feedback generator applies a first haptic profile to each pedal between the neutral position (p.sub.n) and the activation position (p.sub.act) and a second haptic profile from the activation position (p.sub.act) toward the end-of-travel position (p.sub.f).

A method of controlling and optimizing braking and directional control of a vehicle operated on a contaminated, compliant, or non-compliant surface. The method includes steps of: collecting data from a plurality of sensors, the data being indicative of a condition of the contaminated, compliant, or non-compliant surface; sending the data to a neural controller having an algorithm configured to process the data. The algorithm includes: determining optimum braking and directional control instructions for the vehicle, generating warnings and alerts based on the calculated optimum braking and directional control instructions, and sending the optimum braking and directional control instructions to a braking and steering system of the vehicle and the warnings and alerts to an alert and warning system of the vehicle. The method further includes adjusting the steering and directional control of the braking and steering system in accordance with the optimum braking and directional control instructions provided by the neural controller.

A method for controlling brakes includes receiving, by a controller, a first wheel speed from a first wheel speed sensor of a first wheel arrangement, receiving, by the controller, a second wheel speed from a second wheel speed sensor of a second wheel arrangement, calculating, by the controller, a pressure correction, and adjusting, by the controller, a pressure command for at least one of the first wheel arrangement and the second wheel arrangement.

A system, apparatus and method provide emergency differential braking for effecting braked steering of an aircraft. A brake input device is provided that not only allows for emergency and parking brake functions, but also enables differential braking. The brake input device (e.g., a parking and/or emergency brake lever, pedal, handle, etc.) can be used in a brake system including a brake system control unit (BSCU), one or more electro-mechanical actuator controllers (EMACs) and a brake assembly including one or more electrical actuators. Each EMAC is electrically coupled to one or more of the actuators so as to provide electrical power for driving the actuators. Each EMAC is also communicatively coupled to the BSCU so as to receive braking data therefrom. In an emergency, the input device sends braking signals directly to the brake actuators.
