Abstract: A system for controlling turbocharger shaft speed for an internal combustion engine (ICE) includes sensors and actuators and control modules in communication with the sensors and actuators. The control modules store and execute control logic that generates a predicted shaft speed from turbocharger shaft speed data. A shaft speed control algorithm (SSCA) is selectively initialized. The SSCA generates lower and upper limits to turbocharger flow corrections applied via the actuators. Closed loop control outputs are applied selectively to the actuators to control a mass flow through a compressor of the turbocharger. The SSCA selectively determines the shaft speed has exceeded a threshold, and the actuators alter a pressure ratio of the ICE. The SSCA operates the turbocharger stably within predefined hardware limits at an optimum shaft speed while maintaining constant flow across a range of pressure ratios. A long-term memory learning process trims turbocharger performance.

Abstract: A system for controlling a transmission state of a vehicle includes a controller connected to a first drive system and a first transmission including a gear system, a first clutch and a second clutch. The controller is configured to receive a request to change from an initial transmission state to a target transmission state when a propulsion torque is applied to the vehicle. The controller is configured to distribute the propulsion torque such that all of the propulsion torque is applied by a second drive system and the first drive system does not provide any propulsion torque to the vehicle, fully release an off-going clutch from the gear system, control a motor speed based on a rotational speed relation of the target transmission state to reduce a slip speed of the on-going clutch, and fully engage an on-coming clutch to put the first drive system in the target transmission state.

Abstract: A graphics projector for use in a vehicle includes a light source module. The light source module may include an LED array configured to produce a source light. The light source module further includes an optical filter in optical communication with the led array. The optical filter is configured to receive the source light and transmit a filtered light. The light source module further includes a focusing lens in optical communication with the optical filter. The focusing lens is configured to receive the filtered light and transmit a narrow-beam light. The graphics projector also includes an optical collimator in optical communication with the light source module. The optical collimator is configured to receive the narrow-beam light and transmit a collimated light. The graphics projector also includes an optoelectrical mirror in optical communication with the optical collimator. The optoelectrical mirror is configured to direct the collimated light to form a graphic.

Abstract: A system in a vehicle includes a controller to implement a neural network to provide current commands based on inputs. The inputs include a torque input. The system also includes a current controller to provide a three-phase voltage through an inverter based on the current commands from the controller. An electric traction motor provides drive power to a transmission of the vehicle based on injection of the three-phase voltage. The current commands resulting from implementation of the neural network are corrected based on estimated torque resulting from the injection of the three-phase voltage to the electric traction motor.
