Vehicle anomalous behavior detection

A method comprising:

• receiving, at a device from a first sensor, first sensor data indicative of an operational status of a system, the system of a specified system type;
• receiving, at the device from a second sensor, second sensor data associated with an adaptive performance metric adjustment criterion;
• determining, at the device, whether the second sensor data satisfies the adaptive performance metric adjustment criterion;
• based on determining that the second sensor data satisfies the adaptive performance metric adjustment criterion, selectively determining an adaptive performance metric based on the second sensor data;
• comparing, at the device, the first sensor data to the adaptive performance metric to identify anomalous behavior of the system;
• and
• generating a maintenance alert at the device based on determining that the first sensor data fails to satisfy the adaptive performance metric.

• receiving, from a first sensor, first sensor data indicative of an operational status of a system, the system of a specified system type;
• receiving, from a second sensor, second sensor data associated with an adaptive performance metric adjustment criterion;
• determining whether the second sensor data satisfies the adaptive performance metric adjustment criterion;
• based on determining that the second sensor data satisfies the adaptive performance metric adjustment criterion, selectively determining an adaptive performance metric based on the second sensor data;
• comparing the first sensor data to the adaptive performance metric to identify anomalous behavior of the system;
• and
• generating a maintenance alert based on determining that the first sensor data fails to satisfy the adaptive performance metric.
