Abstract:
Systems and methods for coordinating and controlling vehicles, for example heavy trucks, to follow closely behind each other, or linking to form a platoon, in a convenient, safe manner and thus to save significant amounts of fuel while increasing safety. In an embodiment, on-board controllers in each vehicle interact with vehicular sensors to monitor and control, for example, relative distance, relative acceleration/deceleration, and speed. Various data is supplied by the vehicle's onboard systems to a Network Operations Center. The data generated locally from the vehicle's onboard sensors is combined in some embodiments to provide multiple modalities for identifying partner vehicles as well as managing operation of vehicles in close proximity to one another. Various techniques for improving relative position data are also disclosed.
Abstract:
Systems and methods for coordinating and controlling vehicles, for example heavy trucks, to follow closely behind each other, or linking to form a platoon. In one aspect, on-board controllers in each vehicle interact with vehicular sensors to monitor and control, for example, relative distance, relative acceleration or deceleration, and speed. In some aspects, a lead vehicle can wirelessly transmit information from various electronic control units (ECUs) to ECUs in a rear vehicle. A rear vehicle can then apply transformations to the information to account for a desired following distance and a time offset. ECUs onboard the rear vehicle may then be controlled based on the ECUs of the lead vehicle, the desired following distance, and the time offset.
Abstract:
Systems, methods, controllers and algorithms for controlling a vehicle to closely follow another vehicle safely using automatic or partially automatic control are described. The described control schemes are well suited for use in vehicle platooning and/or vehicle convoying applications, including truck platooning and convoying controllers. In one aspect, methods of initiating a platoon between a host vehicle and a platoon partner are described. In another aspect, a number of specific checks are described for determining whether a platoon controller is ready to initiate platoon control of the host vehicle. In another aspect, a platoon controller that includes a state machine that determines the state of the platoon controller is described. In another aspect, methods for generating braking alerts to a driver of a vehicle while the vehicle is being at least semi-automatically controlled by a platoon controller are described.
Abstract:
A system with one or more transceiver antenna assemblies for installation in vehicle side-view mirrors to enable communication with nearby vehicles. Each transceiver antenna assembly may have one or two antenna arrays implemented on a single printed circuit board, protected by an antenna housing to mount the transceiver antenna inside the mirror assembly. Each antenna array in a dual-channel transceiver antenna may transmit and receive data over one of two DSRC channels. One channel may be used to transmit and receive vehicle data only and the other channel may be used to transmit and receive both vehicle data and audio/video (A/V) data. Each antenna array is connected to a vehicle radio that processes received signals and prepares signals for transmission. Such a transceiver antenna system, particularly when mounted within the side view mirror assembly of a truck, may be especially useful for communication in truck platooning.
Abstract:
A system and method for mitigating or avoiding risks due to hazards encountered by platooning vehicles. The system and method involve interrogating, with one or more sensors, a space radially extending from a lead vehicle as the lead vehicle travels over the road surface, perceiving the environment within the space, ascertaining a hazard caused by an object in the space, and causing a following vehicle, operating in a platoon with the lead vehicle, to take a preemptive braking action to avoid or mitigate risks resulting from the hazard caused by the object in the space.

Abstract:
Disclosed herein are a method and apparatus for automated following behind a lead vehicle. The lead vehicle navigates a path from a starting point to a destination. The lead vehicle and the following vehicle are connected via V2V communication, allowing one or more following vehicles to detect the path taken by the lead vehicle. A computerized control system on the following vehicle (a Follow-the-Leader, or FTL, system) allows the following vehicle to mimic the behavior of the lead vehicle, with the FTL system controlling steering to guide the following vehicle along the path previously navigated by the lead vehicle. In some embodiments, the lead vehicle and following vehicle may both use Global Navigation Satellite System (GNSS) position coordinates. In some embodiments, the following vehicle may also have a system of sensors to maintain a gap between the following and lead vehicles.
Abstract:
A variety of methods, controllers and algorithms are described for identifying the back of a particular vehicle (e.g., a platoon partner) in a set of distance measurement scenes and/or for tracking the back of such a vehicle. The described techniques can be used in conjunction with a variety of different distance measuring technologies including radar, LIDAR, camera based distance measuring units and others. The described approaches are well suited for use in vehicle platooning and/or vehicle convoying systems including tractor-trailer truck platooning applications. In another aspect, technique are described for fusing sensor data obtained from different vehicles for use in the at least partial automatic control of a particular vehicle. The described techniques are well suited for use in conjunction with a variety of different vehicle control applications including platooning, convoying and other connected driving applications including tractor-trailer truck platooning applications.
Abstract:
A variety of controllers, control architectures, systems, methods and algorithms are described for controlling a host vehicle's participation in a platoon. In various embodiments, a vehicle platooning control system includes at least two of (i) a platoon controller, (ii) a gateway processor, and (iii) a vehicle interface controller. The platoon controller is configured to determine torque and braking requests for at least partially automatically controlling the host vehicle to platoon with a platoon partner. The gateway processor coordinates communications between a host vehicle and the platoon partner. The vehicle interface controller manages communications between the platoon controller and one or more host vehicle control units. The vehicle interface controller may also include a safety monitor that includes one or more safety monitoring algorithms that verify that platooning is safe.
