Embodiment Construction

[0043] The applicant has proposed various vehicle formation systems in which a second vehicle and potentially additional vehicles are automatically or semi-automatically controlled to closely follow the lead vehicle in a safe manner. For example, US Application Nos. 13 / 542,622, 13 / 542,627, and 14 / 292,583; US Provisional Application Nos. 61 / 505,076, 62 / 249,898, 62 / 343,819, 62 / 377,970; and PCT / US2014 / 030770 PCT applications No. , PCT / US2016 / 049143 and PCT / US2016 / 060167 describe various vehicle formation systems in which following vehicles are at least partially automatically controlled to closely follow a designated lead vehicle. Each of these earlier applications is incorporated herein by reference.

[0044] One of the goals of formation is often to maintain a desired longitudinal distance between formation vehicles, which is often referred to herein as the "desired clearance". That is, it is desirable for a following vehicle (eg, a following truck) to maintain a specified cle...

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 unitsand 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.

Description

[0001] CROSS-REFERENCE TO RELATED APPLICATIONS [0002] This application claims priority to US Application Nos. 15 / 590,715 and 15 / 590,803, filed May 9, 2017, and PCT Application No. PCT / US2016 / 060167, filed November 2, 2016, each of which is incorporated by reference Incorporated herein in its entirety. technical field [0003] The present invention generally relates to systems and methods for enabling vehicles to safely follow each other closely using automatic or partially automatic control. Background technique [0004] Significant progress has been made in the field of autonomous and semi-autonomous vehicles in recent years. One part of vehicle automation involves vehicle escort systems that enable vehicles to follow closely together in a safe, efficient and convenient manner. Following closely behind another vehicle has significant fuel saving benefits, but is generally unsafe when done manually by the driver. One type of vehicle escort system is sometimes referred ...
