Abstract

Methods and systems are provided for controlling an electrical system of a vehicle. Sensors are used to obtain first data for a first path of calculations and second data for a second path of calculations. The first path comprises a first plurality of calculations of generating a value of a parameter pertaining to the electrical system, and the second path comprises a second plurality of calculations of monitoring the electrical system with respect to the first path. A processor is coupled to the plurality of sensors, and is configured to determine whether a data frozen flag is active, perform the first plurality of calculations of the first path using the first data if the first data flag is inactive, and perform the second plurality of calculations of the second path if the first data flag is active.
