1. A method for self-driving vehicle collision avoidance, the method comprising:
receiving, with a control system of a self-driving vehicle, at least one vehicle dynamics attribute pertaining to the self-driving vehicle, and a velocity of the self-driving vehicle;
determine a safety field for the self-driving vehicle based on the at least one vehicle dynamics attribute and the velocity of the self-driving vehicle;
control at least one sensor of the self-driving vehicle according to the safety field, wherein the at least one sensor is operated to monitor the safety field during operation of the self-driving vehicle; and
determining a safe stopping distance based on the at least one vehicle dynamics attribute and the velocity of the self-driving vehicle, and determining the safety field based on the safe stopping distance.
