Abstract
A method for operating a vehicle electronic stability control ('ESC') system utilizing values for a variable obtained from a primary source and a redundant source includes the steps of receiving a first value for the variable from the primary source, receiving a second value for the variable from the redundant source, generating a normalized value as a function of the first value and the second value, determining whether the primary source is operating correctly, utilizing the first value for operation of the vehicle ESC system if the primary source is operating correctly, and utilizing the second value for operation of the vehicle ESC system if the primary source is not operating correctly and the second value is not greater in absolute value than the normalized value.
