Publication number: 20130278441Abstract: Device, system and method, in a vehicle communication system, to transmit wirelessly the position, heading and speed of a vehicle or other moving object. In a key embodiment the vehicle is other than the transmitting vehicle. Some embodiment use local sensors on a first vehicle, such as cameras, sonar, radar or LIDAR to identify the relative position, heading and speed of a second vehicle relative to the first, transmitting, vehicle. An embodiment uses the location of the vehicle whose information is being transmitted as the identification of the same vehicle. Embodiments also receive these messages.

Publication number: 20130279491Abstract: 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.Type: ApplicationFiled: March 28, 2013Publication date: October 24, 2013Applicant: ZETTA RESEARCH AND DEVELOPMENT LLC - FORC SERIESInventors: Kim T.

Methods are provided for limiting the number of duplicated transmissions. Methods are provided for limiting the scope of forwarded message. One embodiment uses the distance of the message originator to a first message forwarder to limit duplicate messages.

Publication number: 20130279392Abstract: 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.Type: ApplicationFiled: March 28, 2013Publication date: October 24, 2013Applicant: ZETTA RESEARCH AND DEVELOPMENT LLC - FORC SERIESInventors: Kim T.

Publication number: 20130279393Abstract: 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.
