Predictive maintenance and diagnostics using modular condition monitoring

A computing system, comprising:

• a data storage device, the data storage device comprising damage accumulation information for a type of electronic module included in one or more autonomous vehicles;
• a processor;
• and
• one or more memory devices that store instructions that, when executed by the processor, cause the processor to perform acts comprising:
• defining a damage accumulation threshold for the type of electronic module based upon the damage accumulation information in the data storage device, wherein the damage accumulation threshold is an indicator of condition degradation that prompts servicing to the type of electronic module, wherein the damage accumulation information comprises at least logged vibrations to which electronic modules of the one or more autonomous vehicles have been exposed over time;
• receiving additional damage accumulation information from a data logger of a particular autonomous vehicle, the additional damage accumulation information being indicative of particular damage accumulation to a particular electronic module of the particular autonomous vehicle, the data logger being configured to monitor the particular damage accumulation to the particular electronic module of the particular autonomous vehicle;
• and
• modifying the damage accumulation threshold for the type of electronic module based upon the additional damage accumulation information from the data logger of the particular autonomous vehicle.

A computing system, comprising:

• a computer-readable storage medium that comprises instructions that, when executed by one or more processors, cause the one or more processors to perform acts comprising:
• receiving damage accumulation information from a data logger of an autonomous vehicle, the damage accumulation information being indicative of damage accumulation to an electronic module, the data logger being configured to monitor the electronic module, the data logger being at least one of attached to or included as part of the electronic module, the damage accumulation information comprising information specifying an amount of time that the electronic module has been exposed to one or more environmental conditions;
• identifying a type of the electronic module;
• identifying a damage accumulation threshold for the type of the electronic module, wherein the damage accumulation threshold for the type of the electronic module is based on fleet-wide damage accumulation information for the type of the electronic module from a plurality of autonomous vehicles in a fleet, wherein the fleet-wide damage accumulation information for the type of the electronic module comprises at least logged vibrations to which electronic modules of the plurality of autonomous vehicles in the fleet have been exposed over time, wherein the damage accumulation threshold for the type of the electronic module is modified over time as additional fleet-wide damage accumulation information for the type of the electronic module is received;
• generating a predicted maintenance schedule for the electronic module of the autonomous vehicle based upon the damage accumulation information from the data logger, the type of the electronic module, and the damage accumulation threshold for the type of the electronic module;
• and
• outputting the predicted maintenance schedule for the electronic module from the computing system.
