Abstract
A system and a method of generating a reliability prediction for components of a vehicle. The system and the method include implementing importance sampling in dynamic vehicle systems when the vehicle is subjected to time-dependent random terrain input. Alternatively, simulation data may be implemented. The system and the method include determining a decorrelation length, scaling up the standard deviation of white noise, and calculation of a likelihood ratio.
