Method and system for controlling electrical systems of vehicles
First Claim
1. A method for controlling an electrical system of a vehicle using first data for a first path of calculations and second data for a second path of calculations, the first path comprising a first plurality of calculations of generating a value of a parameter pertaining to the electrical system, the second path comprising a second plurality of calculations of monitoring the electrical system with respect to the first path, and the method comprising the steps of:
- determining whether the first data is ready for processing along the first path using a processor;
performing calculations of the first path using the first data and the processor;
performing calculations of the second path using the processor and the second data if the first data is not ready for processing along the first path,wherein;
the step of performing calculations of the first path comprises performing the calculations of the first path via time sampling at a first rate via the processor; and
the step of performing calculations of the second path comprises performing calculations of the second path via time sampling at a second rate via the processor, the second rate being different from the first rate.

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.

10. A method for controlling an electrical system of a vehicle using control data for a control path of a first plurality of calculations of the electrical system and monitoring data for a monitoring path of a second plurality of calculations for monitoring the control path, the method comprising the steps of:
-
determining whether a plurality of data frozen flags are active using a processor, each of the plurality of data frozen flags corresponding to a respective one of the first plurality of calculations of the first path and a respective one of the second plurality of calculations of the second path; performing those of the first plurality of calculations for which the corresponding data frozen flag is inactive using the processor; performing those of the second plurality of calculations for which the corresponding data frozen flag is active using the processor; storing results of the second plurality of calculations upon completion of the second plurality of calculations; and setting the data frozen flag to inactive using the processor upon completion of the second plurality of calculations. - View Dependent Claims (11, 12, 13)
