Abstract: A method of controlling a vehicle includes determining a current operating situation of the vehicle, and identifying a subset of a plurality of sensors of the vehicle needed to provide data to enable a vehicle control function for the current operating situation of the vehicle. A remainder of the plurality of sensors is disengaged to reduce electric energy usage by the vehicle while the vehicle is operating in the current operating situation of the vehicle. A sampling rate for the selected subset of sensors may be reduced to further reduce energy usage of the vehicle. Additionally, an energy reduction processing strategy may be implemented to reduce a processor frequency or a voltage of a computing device used to provide the vehicle control function to further reduce energy usage of the vehicle.

Abstract: Methods and systems are provided for controlling a temperature of a processor of a controller. In one embodiment, a method includes: identifying a status of at least one task of a plurality of software tasks performed on a first processor to be a hot task based on the software task's contribution to a temperature of the first processor; and selectively controlling the temperature of the first processor based on the identified status.

Abstract: A method of ordering memory access by an instruction cache of a central processing unit on a global memory device. A signal list of a link map file is extracted in the global memory device. Memory access traces relating to executed tasks are accessed from the signal list. Memory locations accessed in the global memory device from the access traces are identified. A correlation value for each pair of memory locations accessed in the global memory device is determined. Correlation values of the pairs of memory locations are determined, wherein the correlation values are computed based on a proximity of executable instructions utilizing the respective pair of memory locations. Accessed memory locations within the global memory device are reordered as a function of the determined correlation values. An executable file accessing the global memory device is modified.

Abstract: A lane centering fusion system including a primary controller determining whether a vehicle is centered within a lane of travel. The primary controller includes a primary lane fusion unit for fusing lane sensed data for identifying a lane center position. A secondary controller determines whether a vehicle is centered within a lane of travel. The secondary controller includes a secondary lane fusion unit for fusing lane sensed data for identifying the lane center position. The primary controller and secondary controller are asynchronous controllers. A lane centering control unit maintains the vehicle centered within the lane of travel. The lane centering control unit utilizes fusion data output from the primary controller for maintaining lane centering control. The lane centering control unit utilizes fusion data output from the secondary controller in response to a detection of a fault with respect to the primary controller.

Abstract: A system and method for scheduling the execution of multiple mixed-criticality software applications on the same processor. The method separates higher critical, but lower operational rate, software applications into multiple segments so that the separated segments cause the lower rate applications to have a higher rate so that they operate before the lower critical software applications. Alternately, the method increases the length of a lower critical, but higher frequency, software application so that the software application has a lower frequency than the more critical application so that the more critical application has a higher priority.
