Systems and methods for managing communications between vehicles
First Claim
1. A method for managing platoonable vehicles comprising:
- establishing a wireless link between a first vehicle and a second vehicle;
attempting to start a draw-in portion of a platooning engagement between the first vehicle and the second vehicle;
in response to receiving at least a threshold amount of packets per a period of time over the wireless link;
(1) causing the first vehicle and the second vehicle to start the draw-in portion of the platooning engagement;
or(2) continuing a steady state portion of the platooning engagement;
in response to receiving less than the threshold amount of packets per a period of time over the wireless link;
(1) causing the first vehicle and the second vehicle to not start the draw-in portion of the platooning engagement;
or(2) starting the dissolve portion of the platooning engagement; and
wherein the threshold amount of packets is based at least in part on a distance between the first vehicle and the second vehicle, and wherein the packets are safety critical.

Abstract
Systems and methods for increasing the efficiency of vehicle platooning systems are described. In one aspect, drivers are more likely to enjoy a system if it begins platooning as desired and does not accidently end platoons. When a certain amount of data packets sent between vehicles are dropped, systems typically will either not engage in a platoon or end a current platoon. When a platoon has a very small gap between vehicles, the platoon should end—or not start, when a certain amount of packets are dropped. However, if a gap is large enough to provide a driver with more time to react, a system may accept a greater amount of dropped packets before it refuses to start a platoon or causes the end of a platoon.

1. A method for managing platoonable vehicles comprising:
-
establishing a wireless link between a first vehicle and a second vehicle; attempting to start a draw-in portion of a platooning engagement between the first vehicle and the second vehicle; in response to receiving at least a threshold amount of packets per a period of time over the wireless link; (1) causing the first vehicle and the second vehicle to start the draw-in portion of the platooning engagement;
or(2) continuing a steady state portion of the platooning engagement; in response to receiving less than the threshold amount of packets per a period of time over the wireless link; (1) causing the first vehicle and the second vehicle to not start the draw-in portion of the platooning engagement;
or(2) starting the dissolve portion of the platooning engagement; and
wherein the threshold amount of packets is based at least in part on a distance between the first vehicle and the second vehicle, and wherein the packets are safety critical. - View Dependent Claims (2, 3)

4. A method for managing platoonable vehicles comprising:
-
transmitting data packets over a wireless link between a first vehicle and a second vehicle; and performing an action in response to receiving;
(1) less than a threshold amount of data packets per an amount of time over the wireless link;
(2) data packets at a rate below a threshold rate over the wireless link;
or (3) data packets with a latency below a threshold latency over the wireless link, wherein the threshold amount of packets and the threshold rate are based at least in part on a distance between the first vehicle and the second vehicle, and wherein the packets are safety critical. - View Dependent Claims (5, 6, 7)

8. A method for managing platoonable vehicles comprising:
-
establishing a wireless link between a first vehicle and a second vehicle; attempting to start a draw-in portion of a platooning engagement between the first vehicle and the second vehicle; in response to receiving a first amount of packets per an amount of time over the wireless link at a first location, causing a first action to occur including; (1) causing the first vehicle and the second vehicle to start the draw-in portion of the platooning engagement; (2) continuing a steady state portion of the platooning engagement; (3) causing the first vehicle and the second vehicle to not start the draw-in portion of the platooning engagement;
or(4) starting a dissolve portion of the platooning engagement; in response to receiving a second amount of packets per an amount of time over the wireless link at a second location, causing a second action to occur including; (1) causing the first vehicle and the second vehicle to start the draw-in portion of the platooning engagement; (2) continuing a steady state portion of the platooning engagement; (3) causing the first vehicle and the second vehicle to not start the draw-in period of the platooning engagement;
or(4) starting the dissolve portion of the platooning engagement; and
wherein the first and second amounts of packets are based at least in part on a distance between the first vehicle and the second vehicle, and wherein the packets are safety critical. - View Dependent Claims (9, 10, 11, 12, 13, 14)
