Abstract: A method for adaptive real-time optimization of a power or torque split in a vehicle having first and second propulsion sources and a reinforcement-learning-based split controller for controlling a power or torque distribution between the propulsion sources. The method includes: initializing an optimal power or torque split matrix and a learning feedback variable; obtaining a vehicle power or torque setpoint; calculating first and second optimal power or torque setpoint respectively for the propulsion sources based on a power split value derived from optimal power or torque split matrix and the vehicle power setpoint or torque setpoint; controlling the first propulsion source using the first optimal power or torque setpoint, and controlling the second propulsion source using the second optimal power or torque setpoint; using a machine learning algorithm of the controller for calculating a learning feedback variable based on measured or estimated power or torque output feedback.

Abstract: This invention relates to a method of cooling an engine for an automobile, in particular to a method of operating a cooling system having a variable coolant flow control valve. The cooling system is operated in dependence upon the difference between a desired operating temperature and a measured operating temperature. If this difference falls within a first and a second predetermined threshold, the temperature control is effected by operation of the valve in dependence upon the difference. The method also includes operation of a variable speed fan and a variable speed pump, in dependence upon the difference between a desired operating temperature and a measured operating temperature.

Abstract: The present invention relates to an electronically driven pressure boosting system that is used to boost the torque output of an internal combustion engine. The system comprises an electrically driven pressure charging device, an electrical supply system for providing electrical power to drive the pressure charging device including a battery and an engine-driven battery recharger, and an electronic control system for controlling the operation of the pressure charging device and the electrical supply system. The electronic control system determines one or more allowable operating limits to the operation of the pressure charging device based on the state of the electrical supply system, and drives the pressure charging device using the engine-driven battery recharger when the state of the electrical supply system is within an acceptable range.
