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 redundant computing architecture includes a first control unit, a second control unit, and a switch. The first control unit is configured to provide a first control signal in response to a sensory input and is further configured to provide a health status indicator that is indicative of a fault condition within the first control unit. Additionally, the second control unit is configured to provide a second control signal in response to the sensory input. Each of the first and second control signals is respectively operative to control an actuator. The switch is configured to: receive the health status indicator, the first control signal, and second control signal; provide the first control signal to the actuator if this health status indicator does not indicate a fault: and provide the second control signal to the actuator if this health status indicator does indicate a fault.

Abstract: A system for determining a representative vehicle software configuration for a subset vehicles that are part of a group of vehicles. The system includes one or more processors and a memory coupled to the one or more processors, where the memory stores data comprising a database and program code that, when executed by the one or more processors, causes the system to select a module configuration that is part of a set of combined module configurations as the representative vehicle software configuration based on at least one predefined criteria.
