    摘要: Systems and methods for coordinating and controlling vehicles, for example heavy trucks, to follow closely behind each other, or linking, 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. Additional safety features in at least some embodiments include providing each driver with one or more visual displays of forward and rearward looking cameras. Long-range communications are provided for coordinating vehicles for linking, and for communicating analytics to fleet managers or others.

    摘要: Systems and methods for causing a vehicle to avoid an adverse action are described. In one aspect, a sensor on first vehicle may determine the existence and location of lane markers or objects, and use that information to cause a second vehicle to avoid exiting its lane or colliding with an object. Data transmitted from a first vehicle to a second vehicle may be used to determine a path for the second vehicle, such that it avoids an adverse action. This data may include information used to determine a pose of the second vehicle, kinematics of the second vehicle, determine dimensions of the second vehicle, and potential adverse actions. This data may be transmitted while the vehicles are platooning.

    摘要: Systems and methods for platooning vehicles are described. In some aspects, vehicles use sensors to determine a gap between each other. In response to the gap increasing beyond a threshold amount, and a threshold amount of torque being commanded by each of the vehicles, reducing the amount of torque being commanded by the front vehicle. The gap may be determined at least in part by sensors such as a radar, a lidar, and/or a camera. These sensors may be mounted on either a rear vehicle in the platoon, or a front vehicle in the platoon.

    摘要: Systems and methods for increasing the safety of vehicle platooning systems are described. In one aspect, a determination is made as to how many trailers are connected to a tractor, and whether those trailers and any dollies are equipped with an Anti-Lock Braking System. For example, multiple processes for determining whether an Anti-Lock Braking System is operating correctly may be employed to prevent false positives and false negatives. Such processes may determine rates of messages received from Anti-Lock Braking System units, types of messages received from Anti-Lock Braking System units, and/or amounts of types of messages received from Anti-Lock Braking System units.

    摘要: Systems and methods are described for coordinating and controlling vehicles, for example heavy trucks, to follow closely to behind each other, or linking to form a platoon. In one aspect, on-board controllers in each vehicle interact with vehicle sensors to monitor and control, for example, gross vehicle weight, axle loads, and stopping distance. In some aspects, two vehicles can determine information associated with their gross weight and axle load, and apply that information to assist with determining a bounding box indicating which vehicle will take longer to stop. Based on which vehicle will take longer to stop, an order of vehicles in a potential platoon is determined.

    摘要: The present invention relates to a method and system for enabling vehicles to closely follow one another through partial automation. Following closely behind another vehicle can have significant fuel savings benefits, but is unsafe when done manually by the driver. By directly commanding the engine torque and braking of the following vehicle while controlling the gap between vehicles using a sensor system, and additionally using a communication link between vehicles that allows information about vehicle actions, such as braking events, to be anticipated by the following vehicle, a Semi-Autonomous Vehicular Convoying System that enables vehicles to follow closely together in a safe, efficient and convenient manner may be achieved.
