1. An on-board computer system for logging sensor data for an autonomous vehicle, the on-board computer system comprising:
- a plurality of sensors for monitoring sensor data regarding operation of the autonomous vehicle and an environment in which the autonomous vehicle is present;
a processor for analyzing the sensor data; and
a first memory in which the monitored data is stored to log the sensor data received from the plurality of sensors of the autonomous vehicle,wherein the processor assesses criticality of a current situation for the autonomous vehicle by analyzing the sensor data and determines processing capability of the processor based on the assessment of criticality of the current situation, andwherein the processor determines whether to log sensor data in the first memory or to, instead, hold sensor data in a second memory until a future time to be determined, wherein the determination to store or hold is based on the determined criticality of the current situation to reduce the load on processing capability of the processor, wherein the first memory is a hard drive and the second memory is a RAM.

Abstract
An on-board computing system for determining an opportune time to log data into a first memory. A sensor system collects data of a vehicle'"'"'s environment. A controller of the on-board computing system logs the data to a first memory when it determines an opportune time to log data to the first memory. The controller holds data in a second memory if it determines it is not an opportune time to log data into the first memory. The controller resumes logging data to the first memory when an opportune time presents itself.
