    Abstract: A method for determining a state of health (SOH) value for an electric power steering (EPS) system in a vehicle includes estimating a first Self-Aligning Torque (SAT) value using a tire dynamics model, which includes modeled dynamics in the linear region of a lateral force acting on the vehicle tires. The method also includes estimating a second SAT value using an extended state observer and nominal parameters for the EPS system, and calculating a variance between the first and second SAT values. The controller monitors a progression of the calculated variance over a calibrated interval using the controller to thereby determine the SOH value, and automatically executes a control action using the SOH value. An EPS system for a vehicle includes a steering wheel, torque and angle sensors, a rack and pinion assembly, a steering motor, and the controller. A vehicle is also disclosed having the same controller.

    Abstract: A method for allocating forces among the corners of a vehicle having a redundant actuator suite includes determining a set of desired forces at the center of gravity of the vehicle, and allocating the set of desired forces among the corners of the vehicle as virtual control commands using a controller. The method also includes mapping the virtual control commands at the corners to actual or true control commands at the corners, and controlling a plurality of actuators at the corners using the actual or true control commands. The actuators may include friction brakes and wheel motors. Mapping the virtual control commands may include using a Least Squares formulation. Control of the actuators may be prioritized with respect to each other using weighting matrices. A vehicle includes a controller having actuators and a controller configured for executing the above method.

    Abstract: A control system for warning a following vehicle of a potential collision with a leading vehicle. The leading vehicle includes a detection system for detecting the presence and velocity of the following vehicle. The control system determines a desired distance between the leading vehicle and the following vehicle based on the speed of the leading vehicle. The control system subtracts the desired distance from the actual distance to generate a distance error signal, and compares the distance error signal to a threshold. If the error signal is greater than the threshold, the control system may provide one or more operations, such as flashing hazard lights to warn the following vehicle, or taking other course of action in the event of an imminent collision, such as pre-tensioning seat belts and closing windows of the leading vehicle.
