Elastic computing for in-vehicle computing systems

An in-vehicle system, comprising:

• one or more communication links configured to communicatively couple to a first local computing device, and to a second local computing device;
• and
• an elastic computing module communicatively configured to couple to the first local computing device and the second local computing device, the elastic computing module comprising one or more processors and a memory for holding executable instructions which, when executed, cause the one or more processors to:
• determine a first set of processing parameters of the first local computing device and a second set of processing parameters of the second local computing device;
• establish a demanded safety parameter of a software application for the vehicle, the demanded safety parameter including an Automotive Safety Integrity Level (ASIL) level;
• and
• dynamically allocate processing of the software application among the first local computing device and the second local computing device to meet the demanded safety parameter of the software application, based upon the first set of processing parameters and the second set of processing parameters, wherein the first set of processing parameters and the second set of processing parameters comprise computing capacities and memory capacities, and wherein the dynamic allocation is further based on load-balancing between a local load and a remote load, the dynamic allocation changing according to changes in processing demands of the software application, availability of local computing resources, and availability of remote computing devices resource, including:
• in response to a predetermined safety demand of the ASIL level,
• deallocate a computer processing resource including a processing core allocated to the software application,
• execute one or more on-device tests including a logic built-in self-test to determine whether the computer processing resource has any detectable issues, then,
• only if the computer processing resource has no detectable issues, re-allocate the computer processing resource to the software application, and
• execute the software application with the re-allocated computer processing resource,
• wherein a first processing partition handles processing related to one or more chassis capabilities, or one or more drivetrain capabilities, or both.
