Title: CONCEPT OF COORDINATING AN EMERGENCY BRAKING OF A PLATOON OF COMMUNICATIVELY COUPLED VEHICLES
Abstract: The present disclosure provides a concept for coordinating an emergency braking of a platoon (100) of communicatively coupled vehicles (110). In response to an emergency situation (120), individual braking control settings are centrally determined (230) for one or more vehicles (110) of the platoon (100) by a managing entity (110-3) managing the platoon (100). The individual braking control settings are communicated (240) from the managing entity (110-3) to the one or more vehicles (110) of the platoon (100). The one or more vehicles (110) of the platoon (100) brake (250) in accordance with its respective individual braking control settings received from the managing entity (110-3).
IPC codes: G05D   1/    02            A I
Claims: number: 1
text: A method (200) for coordinating an emergency braking of a platoon (100) of communicatively coupled vehicles (110), the method comprising:
number: 2
text: The method (200) of claim 1, further comprising
detecting (210) the emergency situation (120) by a vehicle (110-1) of the platoon; and
in response to detecting the emergency situation (120), broadcasting (220) an emergency message from the vehicle (110-1) to other vehicles (110-2; 110-3) of the platoon.
number: 3
text: The method (200) of claim 2, further comprising:
number: 4
text: The method (200) of any one of the previous claims, wherein the individual braking control settings are indicative of a respective braking power to be applied.
number: 5
text: The method (200) of any one of the previous claims, further comprising informing the managing entity (110-3) about individual characteristics and/or a current state of each vehicle of the platoon (100).
number: 6
text: The method (200) of claim 5, wherein determining the individual braking control settings of a vehicle (110) is based on the individual characteristics and/or the current state of the respective vehicle.
number: 7
text: The method (200) of claim 5 or 6, wherein the individual characteristics and/or the current state comprise at least one of weight, braking power, inter-vehicle-distance, speed, tire condition.
number: 8
text: The method (200) of any one of the previous claims, wherein the plurality of vehicles (110) of the platoon (100) are autonomous or at least partially autonomous vehicles, respectively.
number: 9
text: The method (200) of any one of the previous claims, wherein the plurality of vehicles (110) of the platoon communicate via a vehicle-to-vehicle communication system.
number: 10
text: The method (200) of any one of the previous claims, wherein the managing entity (110-3) is a vehicle of the platoon (100) acting as a master vehicle for other vehicles of the platoon acting a slave vehicles.
number: 11
text: A system (100) of a plurality of communicatively coupled vehicles (110), comprising
a first vehicle (110-1) configured to detect an emergency situation and, in response to the detected emergency situation, to broadcast an emergency message to other vehicles;
a second vehicle (110-3) configured to determine, in response to the emergency message, respective braking control parameters for a respective vehicle and to send the respective individual braking control parameters to the respective vehicle; and
a third vehicle (110-2) configured to adjust its braking settings in accordance with its respective individual braking control parameters.
number: 12
text: A vehicle (110-3), comprising:
