1. A method for electronic stability control of a wheeled tactical vehicle and a trailer coupled to the wheeled tactical vehicle, the electronic stability control method comprising:
- receiving substantially in real time at a state estimator of a vehicle arbiter controller, signals associated with current vehicle operating conditions, the current vehicle operating conditions signals including three or more of a wheel speed signal, a velocity signal, a height signal, a steering signal, a throttle signal, a roll/pitch/yaw signal, an acceleration signal, a brake pedal signal, and an active damper signal;
receiving substantially in real time at the state estimator of the vehicle arbiter controller, signals associated with current trailer operating conditions, the current trailer operating conditions signals including three or more of a wheel speed signal, a velocity signal, a height signal, a roll/pitch/yaw signal, and a tongue angle signal;
receiving at the state estimator of the vehicle arbiter controller a signal associated with a mobility traction control system including a mobility keypad, the signal from the mobility traction control system being indicative of a traction mode of the wheeled tactical vehicle selected by a user via the mobility keypad;
providing a brake-based stability control subsystem, a torque-based stability control subsystem, and a drivetrain-based stability control subsystem;
selecting one of the brake-based stability control subsystem, the torque-based stability control subsystem, and the drivetrain-based stability control subsystem as the dominant stability control system for the wheeled tactical vehicle based on the three or more received signals associated with current vehicle operating conditions, the three or more received signals associated with current trailer operating conditions, and the received signal associated with the mobility traction control system; and
providing stability control of the wheeled tactical vehicle and for the trailer coupled to the wheeled tactical vehicle based on the selected dominant stability control subsystem, while disabling the stability control subsystems not selected as dominant.

Abstract
A system and method for stability control of a vehicle and a trailer. The system and method can receive vehicle and trailer operating data or signals and define one of a brake-based stability control subsystem and a torque management-based stability control subsystem as the dominant stability control system. Based on the stability control subsystem defined as the dominant stability control system, the system and method provide stability control for the vehicle and the trailer.

5. A system for stability control of a tactical vehicle and a trailer physically and electrically coupled thereto, the system comprising:
-
first receiving means for receiving three or more of a velocity signal of the tactical vehicle, speed signals from each wheel of the tactical vehicle, a height signal associated with the tactical vehicle, a steering signal associated with the tactical vehicle, a throttle signal associated with the tactical vehicle, a roll/pitch/yaw signal associated with the tactical vehicle, a brake pedal signal, an active damping signal, and at least one signal associated with a current driving condition of the tactical vehicle; second receiving means for receiving a signal from a traction control system, the signal from the traction control system being indicative of a traction mode of the tactical vehicle selected by a user; third receiving means for receiving three or more of a wheel speed of the trailer, a velocity signal of the trailer, a height signal of the trailer, a roll/pitch/yaw signal of the trailer, a trailer tongue angle, and at least one signal associated with current driving condition of the trailer; processing means for defining one of a brake-based stability control subsystem and a torque management-based stability control subsystem as the dominant stability control system of the tactical vehicle based on the signals received by said first, second, and third receiving means; and controlling means for providing stability control of the tactical vehicle and of the trailer based on the defined dominant stability control system. - View Dependent Claims (6, 7, 8, 9)
