Abstract: A method of adaptively reconfiguring controller functions during a frame overrun. A frame overrun condition is detected. A respective task from a plurality of tasks is identified as a largest contributor to the frame overrun. A mode associated with the identified task is identified to correct the frame overrun. Functions are reallocated within the identified task to one or more other tasks until the frame overrun condition is corrected. Respective functions reallocated are identified as a function of the identified mode.

Abstract: A method of establishing traceability for embedded software systems. A design code database is provided for an embedded software system. A test suite database including a plurality of test cases is structured for testing design code of the embedded software system. The structuring of the test cases provides a correspondence from a respective test case to a respective portion of the design code. A processor receives a design code modification to the embedded software. An associated test case is identified for testing the modified design code being based on traceability data. The associated test case is revised to accommodate the modified design code. The modified test cases are integrated into the test suite. A traceability database establishes a one-to-one correspondence between the modified design coder and the modified test case is updated.

Abstract: An on-demand, feature focused data collection system of an automobile vehicle includes at least one data collection device provided with an automobile vehicle. A data collection unit receives data from the at least one data collection device in response to a data collection request submitted by a user. A data scene group combines portions of the data received by the data collection unit and stored in the data collection unit of the automobile vehicle or at a remote server. A control logic device receives the data collection request and activates collection of the data. The control logic device includes: a data collection strategy which differs if different types of the data are available; a reference algorithm loaded or deployed; a storage capacity allocated for the data; and a storage policy employed to save the data.

Abstract: A system for an attention-based perception includes a camera device configured to provide an image of an operating environment of a vehicle. The system further includes a computerized device monitoring the image, analyzing sensor data to identify a feature in the image as corresponding to an object in the operating environment and assign a score for the feature based upon an identification, a location, or a behavior of the object. The computerized device is further operable to define candidate regions of interest upon the image, correlate the score for the feature to the candidate regions of interest to accrue a total region score, select some of the candidate regions for analysis based upon the total region scores, and analyze the portion of the candidate regions to generate a path of travel output. The system further includes a device controlling the vehicle based upon the output.
