Abstract
Systems, methods and apparatuses are provided for detecting faults. The system includes a fault diagnostic computer in an autonomous vehicle configured to, via at least a first platform and a second platform, receive parameter data for processing simultaneously the parameter data in each platform wherein the first and second platforms are redundant configurations of each other wherein the parameter data includes a characteristic of a data; a check platform, coupled to the first and second platforms, for performing a method for checking the parameter data processed by both platforms using a collision test, the method includes: detecting, by applications of the collision test to one or more corresponding data found on each platform, collisions of the data within a tolerance prescribed by the collision test; and determining faults, in either the first platform, the second platform or both, based on results of comparisons of parameter data of the detected collisions.
