1. A communication system for enabling communication between vehicles in a platoon, the system comprising:
- a first emitter and a first receiver, configured to be directed in a forward direction of a vehicle;
a second emitter and a second receiver, configured to be directed in a backward direction of the vehicle; and
a controller in communication with the emitters and the receivers, the controller configured to;
during an initialization phase, determine a position of the vehicle within the platoon and the identity of each vehicle in the platoon, based on signals detected by the first and/or second receivers; and
during a data transmission phase, participate in a token-based data transmission by evaluating a signal received by one of the first or second receivers and causing the emission of a signal either by the corresponding one of the first or second emitters that received the signal should the vehicle be the first or last vehicle in the platoon, or by the other one of the first or second emitters should the vehicle not be the first or last vehicle in the platoon.

Abstract
A system and method are provided for communication between vehicles within a platoon of vehicles. In one embodiment, each vehicle is equipped with forward and backward directed optical emitters and receivers in operable communication with a controller. In an initialization phase, each vehicle determines its position within the platoon and the identification of all vehicles of the platoon. In a data transmission phase, each vehicle takes part in a token-based data transmission.

12. A method of communication between vehicles in a platoon, the method comprising:
-
providing a first emitter and a first receiver directed in the forward direction of a vehicle; providing a second emitter and a second receiver directed in the backward direction of the vehicle; during an initialization phase, determining a position of the vehicle within the platoon and the identity of all vehicles in the platoon, based on signals detected by the first and/or second receivers; and during a data transmission phase, participating in a token-based data transmission by evaluating a signal received by one of the first or second receivers and causing the emission of a signal either by the corresponding one of the first or second emitters that received the signal should the determined position of the vehicle be the first or last vehicle in the platoon, or by the other one of the first or second emitters should the determined position of the vehicle not be the first or last vehicle in the platoon. - View Dependent Claims (13, 14, 15, 16, 17, 18, 19, 20)
