Abstract: A method for characterizing a stiction condition in a manual steering gear includes transmitting a steering input control signal to a rotary actuator, and rotating a steering shaft with constant acceleration, via the rotary actuator, in response to the steering input control signal. A steering output torque is determined while rotating the steering shaft with the constant acceleration, receiving the steering output torque via the controller, and executing a control action when a rate of the received steering output torque exceeds a threshold rate indicative of the stiction condition. A system includes a rotary actuator, a manual steering gear having a steering shaft connected to the rotary actuator, a torque transducer for measuring a steering output torque imparted to the steering shaft by the actuator, and a controller programmed as set forth above.

Abstract: A split vehicle closure assembly for a vehicle utilizes a novel seal assembly, latching mechanism and hinges, all of which cooperate to permit the vehicle closure assembly to selectively seal an opening to a vehicle compartment, preventing, dirt, liquid and fumes from entering through the vehicle closure assembly, or to be opened partially or fully to provide various configurations for access to the compartment through the opening.

Abstract: A method directed to improving the stability of a motor vehicle having front and rear steering capabilities includes determining a coefficient of friction of the road surface with which the motor vehicle is engaged and adjusting a phase gain function of a rear steering mechanism to compensate for the steerability of the motor vehicle over the road surface. A system for improving the stability of a motor vehicle having front and rear steering capabilities includes a control unit, a front steering mechanism in informational communication with the control unit, and a rear steering mechanism in informational communication with the control unit. The rear steering mechanism is responsive through the control unit to road conditions of the road surface.
