Abstract: A method of partitioning tasks on a multi-core ECU. A signal list of a link map file is extracted in a memory. Memory access traces relating to executed tasks are obtained from the ECU. A number of times each task accesses a memory location is identified. A correlation graph between the each task and each accessed memory location is generated. The correlation graph identifies a degree of linking relationship between each task and each memory location. The correlation graph is re-ordered so that the respective tasks and associated memory locations having greater degrees of linking relationships are adjacent to one another. The tasks are partitioned into a respective number of cores on the ECU. Allocating tasks and memory locations among the respective number of cores is performed as a function of substantially balancing workloads with minimum cross-core communication among the respective cores.

Abstract: A method and architecture of reconfiguring software mode management for a system. A prior status mode of a subsystem is identified. The primary controller includes a primary software algorithm for maintaining operations of the subsystem. A mode determination logic function is retrieved in a table for determining whether a mode change occurred. The mode determination logic function associated with the prior mode is executed. A current mode is determined from the table based on results from the execution of the mode determination logic function. An action list associated with the identified current mode in the table is identified. The action list identifies functions for transitioning the nodes from the prior mode to the current node. An action list associated with the current mode including a list of action functions for transitioning the previous mode to the current mode is executed. The table is independently modifiable from the primary software mode management algorithm.

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.
