Abstract
A method includes receiving, by a processing device of a vehicle, one or more measurements related to a component of the vehicle. The method also includes determining, by the processing device, based on the one or more measurements, a failure rate and a mean time to failure (MTTF) for the vehicle component. The method also includes transmitting, by the processing device using a communication interface, the failure rate and the MTTF to one or more destination systems. The method also includes implementing, by the processing device based on a determination of a failure rate increase for the vehicle component, one or more actions to increase an operation lifetime of the vehicle component.
Claims22
A method, comprising:
- receiving, by a processing device of a vehicle, one or more measurements related to a vehicle component of the vehicle;
- determining, by the processing device, based on the one or more measurements, a failure rate and a mean time to failure (MTTF) for the vehicle component;
- transmitting, by the processing device using a communication interface, the failure rate and the MTTF to one or more destination systems;
- and
- implementing, by the processing device based on a determination of a failure rate increase for the vehicle component, one or more actions to increase an operation lifetime of the vehicle component.
An electric vehicle, comprising:
- a memory;
- a communication interface;
- and
- a processing device communicatively connected to the memory, the communication interface, and a vehicle component of the electric vehicle, wherein the processing device is configured to:
- receive one or more measurements related to the vehicle component;
- determine, based on the one or more measurements, a failure rate and a mean time to failure (MTTF) for the vehicle component;
- transmit, using the communication interface, the failure rate and the MTTF to one or more destination systems;
- and
- implement, based on a determination of a failure rate increase for the vehicle component, one or more actions to increase an operation lifetime of the vehicle component.
