SYSTEMS AND METHODS FOR CRITICAL DATA SAVE IN ELECTRONIC CONTROL MODULES

A controller for a vehicle includes at least one processor and at least one memory storing instructions that, when executed by the processor, cause the controller to perform various operations. The operations include determining that a power loss to the controller has occurred. In response to the determination that the power loss has occurred, the operations are structured to determine whether a key switch associated with an engine of the vehicle is on; and, when the key switch is on, save operating data to a ferroelectric random access memory (TRAM) coupled to the controller.
