System and method for implementing pre-cognition braking and/or avoiding or mitigation risks among platooning vehicles
First Claim
Patent Images
1. A system arranged to operate on a following vehicle in a platoon with a lead vehicle, the system configured to:
- receive a notice at the following vehicle from the lead vehicle of a braking event by the lead vehicle;
in response to the notice, coordinating deceleration between the following vehicle and the lead vehicle such that;
the following vehicle brakes before the lead vehicle decelerates; and
the following vehicle reduces velocity more than the lead vehicle,wherein the combination of the braking of the following vehicle before the lead vehicle and the following vehicle reducing velocity more than the lead vehicle results in an increase of a gap between the lead vehicle and the following vehicle.

Abstract
A system and method for mitigating or avoiding risks due to hazards encountered by platooning vehicles. The system and method involve interrogating, with one or more sensors, a space radially extending from a lead vehicle as the lead vehicle travels over the road surface, perceiving the environment within the space, ascertaining a hazard caused by an object in the space, and causing a following vehicle, operating in a platoon with the lead vehicle, to take a preemptive braking action to avoid or mitigate risks resulting from the hazard caused by the object in the space.

11. A system configured to operate on a following vehicle in a platoon behind a lead vehicle, the system configured to:
-
receive data generated by one or more sensors arranged to interrogate a space radially extending from the lead vehicle as the lead vehicle travels over a road surface; ascertain from the data a hazard caused by an object in the space; and coordinating preemptive action, in response to the ascertained hazard, between the lead vehicle and the following vehicle while operating in the platoon, the coordinated preemptive action causing the following vehicle to take a first preemptive action to avoid or mitigate a risk resulting from the hazard caused by the object in the space, the first preemptive action taken by the following vehicle coordinated to occur prior to the lead vehicle taking any second action to avoid or mitigate the risk resulting from the hazard caused by the object in the space. - View Dependent Claims (12, 13, 14, 15, 16, 17, 18, 19, 20, 21, 22, 23, 24, 25, 26, 27, 28, 29, 30, 31)

32. A system operating on a lead vehicle in a platoon with a following vehicle, the system configured to:
-
(a) ascertain a hazard caused by an object in a space adjacent the lead vehicle from data generated by one or more sensors on the lead vehicle; (b) determine a preemptive action for the following vehicle on the lead vehicle, the preemptive action for avoiding or mitigating a risk associated with the hazard; and (c) relay one or more commands to the following vehicle indicative of the determined preemptive action, wherein the following vehicle is arranged to implement the preemptive action in response to the relayed one or more commands.
