Abstract: Systems, methods, and computer-readable media for providing feedback to a driver are provided herein. Vehicle speed or acceleration data can be received for a location on a route. A current acceleration value for the location is derived using the received vehicle speed or acceleration data. A preferred acceleration value for the location is determined based on a preferred speed or acceleration profile that is specific to the route. An indication of a correspondence between the preferred acceleration value for the location and the current acceleration value for the location is then provided. The indication can be, for example, a graphic comparing the preferred and current acceleration values. Based on the indication, a driver can adjust acceleration to conform to the preferred acceleration value.

Abstract: A system and method for real-time, self-learning characterization of fuel injector performance during engine operation. The system includes an algorithm for an engine controller which allows the controller to learn the correlation between the fuel mass and pulse width for each injector in the engine in real time while the engine is running. The controller progressively perceives those pulse widths that achieve the desired fuel mass, while it can continuously adapt what it has learned based on various input variations, such as temperature and fuel rail pressure. The controller then uses the learned actual performance of each injector to command the pulse width required to achieve the desired quantity of fuel for each cylinder on each cycle.

Abstract: Method, control apparatus and powertrain system controller are provided for real-time, self-learning control based on individual operating style. The method calibrates powertrain system performance in a passenger vehicle in real-time based on individual operating style. The method includes powering the vehicle with the system and generating a sequence of system operating point transitions based on an operating style of an operator of the vehicle during the step of powering. The method further includes learning a set of optimum values of controllable system variables in real-time during the steps of powering and generating based on the sequence of system operating point transitions and predetermined performance criteria for the system. The method still further includes generating control signals based on the set of optimum values to control operation of the system.
