    摘要： A device for use in, and system for, a vehicle-to-vehicle (V2V) communication and safety system that uses a hybrid combination of TDMA and CSMA protocols. The synchronized TDMA frame is partitioned into three prioritized time interval classes with differing priorities and dynamically changing sizes based on demand of higher-priority messages. The TDMA portions of a repeating time interval uses self-assigned dense time slots for high-priority safety messages, with one portion for emergency vehicles and road-side units. The CSMA protocol uses remaining available time for lower-priority and overflow messages. The higher-priority time interval classes change size dynamically based on the number of current transmissions. Modulation schemes, but not data link formats, use existing Standards. Embodiments include optimized traffic flow and signal timing.

    摘要： A transceiver in a vehicle-to-vehicle (V2V) communication and safety system that regularly broadcasts safety messages, comprising location, heading and speed, of a subject vehicle, that are free of MAC and IP addresses. The V2V system uses the location of the subject vehicle for vehicle identification, in place of a pre-assigned vehicle ID. Some embodiments broadcast safety message in self-assigned time slots in a synchronized TDMA broadcast architecture, with unusually short inter-message gaps and unusually short messages. The TDMA frame is partitioned into three prioritized time interval classes with differing priorities and dynamically changing sizes based on demand of higher-priority messages. Time slot selection uses weighted algorithms. Selected time slots are held until either a message collision or a timeout occurs. A transceiver equipped vehicle may proxy a different subject vehicle. Embodiments include optimized traffic flow and signal timing.

    摘要： A device and vehicle for use in, and system for, a vehicle-to-vehicle (V2V) communication and safety system that uses TDMA communication architecture with a self-synchronized TDMA time base. The time base starts with a GPS and internal clock, then fine-tunes by averaging the time bases of all vehicles within radio range. In the described algorithms, all vehicles within a communication range rapidly converge on a common time base to high precision. The regularly broadcast safety messages themselves are used for time base synchronizing, eliminating the need for separate time stamps or transmissions. A range group of vehicles, first converges itself, then converges the group on a UTC time via GPS. Embodiments include use of vehicle distances in time computations. Applications anti-collision systems, optimized traffic flow and signal timing.
