Abstract
A scanner monitors a vehicle engine module's performance, such as, for example, a vehicle engine powertrain by creating and compiling performance data either in real time or based on a data post-processing schedule. A preventive maintenance or repair is suggested if the critical boundaries of a probable failure are reached.
Claims8
A method for determining reliability of a vehicle powertrain comprising:
- providing a vehicle powertrain comprising a vehicle power cylinder and an air/exhaust system, wherein the vehicle power cylinder comprises a first group of components and the air/exhaust system comprises a second group of components, wherein each component of the first and second groups of components comprises an associated monitor or sensor structured to monitor or sense performance data of each component associated therewith;
- providing a control module having a communications interface structured to communicate with each monitor or sensor associated with each component of the first and second groups of components to facilitate acquiring the performance data of each component of the first and second groups of components;
- providing a diagnostic tool and monitoring the first group of components of the vehicle power cylinder and the second group of components of the air/exhaust system using each associated monitor or sensor of each component of the first and second groups of components for reliability of each component of the first and second groups of components to capture the performance data of each component of the first and second groups of components;
- compiling the reliability performance data of each component of the first and second groups of components from the control module diagnostic tool into a database;
- providing a scanner and scanning the complied reliability performance data and monitoring the reliability of each component of the first and second groups of components, assigning an input parameter to each component of the first and second groups of components based on the reliability performance data, determining a reliability factor for each of the first and second groups of components based on the input parameter of each of the components within each of the groups being assigned a binary value of either one (1) if failure of the associated component is indicated and zero (0) if no failure is indicated, the number of components in the group, the identity of each component and the reliability of each component in each of the groups, determining a probability of failure of each of the first and second groups;
- multiplying the probability of failure of each of the first and second groups to determine the possibility of failure of the vehicle powertrain;
- and
- in response to the probability of failure being equal to or is greater than a threshold generating a notification for the necessity of preventative maintenance.
