Abstract
There are provided techniques including a system, method, and computer-readable medium for clock drift monitoring and correction for autonomous vehicles. The method may include the steps of: determining that at least one of a first component associated with a first clock or a second component associated with a second clock of a vehicle is unable to synchronize with a common master clock of the vehicle according to a clock synchronization protocol; operating the first component or the second component without synchronization of the first clock or the second clock with the master clock; determining a first value indicating a relative clock drift between the first clock and the second clock; determining that the first value exceeds a first threshold value; and operating the vehicle in a degraded state or performing a mitigating action based at least in part on determining that the first value exceeds a first threshold value.
