1. A system comprising:
a time-of-flight sensor configured to sense a plurality of objects in a field;
a processor, operatively coupled to the sensor, configured to:
track position of a sensed approaching object of the plurality of sensed objects as the sensed approaching object closes,
determine a size and a configuration of the closing object, and
in response to the tracked position and the determined configuration,
calculate a probability of an imminent collision with the closing object before any collision occurs, and
predict a severity of the imminent collision based on at least the size of the closing object; and
at least one countermeasure operatively coupled to the processor,
wherein the processor is further configured to issue a command signal controlling the at least one countermeasure conditioned on the calculated probability and the predicted severity of an imminent collision.
