Abstract
Systems and methods for predictively detecting vehicle failure based on diagnostic trouble codes are provided. In one example, a method is provided, comprising determining a probability of failure of a vehicle based on one or more diagnostic trouble codes (DTCs); and indicating to an operator of the vehicle that failure is likely in response to the probability exceeding a threshold.
Claims20
A method, comprising
- determining a probability of failure of a vehicle based on one or more diagnostic trouble codes (DTCs);
- and
- indicating to an operator of the vehicle that failure is likely in response to the probability exceeding a threshold.
A system, comprising
- a vehicle;
- a plurality of vehicle subsystems;
- a controller with machine-readable instructions stored in non-transitory memory, for:
- receiving one or more diagnostic trouble codes (DTCs) from the vehicle subsystems,
- generating a probability of failure of the vehicle by comparing the one or more DTCs to one or more trained model objects, and
- indicating to an operator of the vehicle that failure is likely if the probability exceeds a threshold.
3 more elements
A method, comprising
- receiving a diagnostic trouble code (DTC) and an engine operating parameter;
- comparing the DTC and engine operating parameter to a trained model object to generate a probability of failure of a vehicle and an instruction;
- and
- in response to the probability of failure being greater than a threshold, displaying the instruction to an operator of the vehicle on a screen.
