Lightweight in-vehicle critical scenario extraction system

An automated data logging system for of a vehicle, the system comprising:

• volatile memory to host sensing data of an environment in a vicinity of the vehicle, the sensing data produced during autonomous operation of the vehicle from at least one sensor device associated with the vehicle;
• non-volatile memory to host extracted data, the extracted data being a subset of the sensing data captured from the at least one sensor device associated with the vehicle;
• and
• processing circuitry configured to:
• detect a critical scenario during the autonomous operation of the host vehicle in the sensing data, wherein the critical scenario is detected based on a comparison of the operation of the vehicle to at least one requirement specified by a vehicle operation safety model;
• perform data extraction on the sensing data, in response to detecting the critical scenario, the data extraction to obtain data indictive of movement details of the operation of the vehicle, wherein the extracted data provides information for reconstruction of the critical scenario in a simulation;
• and
• output the extracted data.

At least one non-transitory machine-readable storage medium comprising instructions that, when executed by at least one processor, cause the at least one processor to perform operations for automated data logging in a host vehicle comprising:

• obtaining data from at least one sensor, the data produced during autonomous operation of the host vehicle;
• detecting a critical scenario during the autonomous operation of the host vehicle in the data obtained from the at least one sensor, wherein the critical scenario is detected based on a comparison of the operation of the host vehicle to at least one requirement specified by a vehicle operation safety model;
• performing data extraction on the data obtained from the at least one sensor, in response to detecting the critical scenario, the data extraction to obtain data indictive of movement details of the operation of the host vehicle, wherein the extracted data provides information for reconstruction of the critical scenario in a simulation;
• and
• outputting the extracted data.
