Abstract: A method for determining, in real-time, an electronic limited-slip differential (eLSD) clutch torque includes receiving vehicle data in real-time, wherein the vehicle data includes a torque request, determining a preliminary eLSD clutch torque using a neural network and the vehicle data, determining clutch torque bounds of the eLSD using a physics-based model, determining whether the preliminary eLSD clutch torque is outside the clutch torque bounds of the eLSD, adjusting the preliminary eLSD clutch torque using clutch torque bounds to determine a final clutch torque of the eLSD in response to determining that the preliminary eLSD clutch torque is outside the clutch torque bounds of the eLSD, and commanding, in real-time, the eLSD to apply the final clutch torque to a clutch of the eLSD.

Abstract: A system for adaptive tire force prediction in a motor vehicle includes a control module that executes program code portions that receive real-time static and dynamic data from motor vehicle sensors, that model forces at each tire of the motor vehicle at one or more incremental time steps, that estimate actual forces at each tire of the motor vehicle at each of the one or more incremental time steps, that adaptively predict tire forces at each tire of the motor vehicle at each of the one or more incremental time steps, that generate one or more control commands for actuators of the motor vehicle, that capture discrepancies between real-time force estimations and nominal force calculations at each tire of the motor vehicle, and that apply compensation parameters to reduce tracking errors in the one or more control commands to the one or more actuators of the motor vehicle.

Abstract: A system for estimating a lateral velocity and a longitudinal velocity of a vehicle includes a plurality of sensors for monitoring data indicative of a travel state of the vehicle and one or more controllers in electronic communication with the plurality of sensors. The one or more controllers executes instructions to receive the data indicative of the travel state of the vehicle from the plurality of sensors. The one or more controllers estimate at least one initial estimated state of the vehicle based on the data indicative of the travel state of the vehicle. The one or more controllers fuse together the data indicative of the travel state of the vehicle with the at least one initial estimated state of the vehicle to determine the lateral velocity and a longitudinal velocity of the vehicle based on a single state estimation scheme.
