The invention discloses an automatic aligning and hinging device and method for a whole-section steel truss girder. The device comprises a main cable transverse opposite-pulling system, a monitoring system, a hoisting system, a local aligning auxiliary tool, an adjusting control system, a temporary hinging device and a fine adjusting device. The monitoring system collects data such as spatial positions and attitude angles of the steel truss girder sections in real time and feeds back information to the adjusting control system; the adjusting control system generates a control instruction based on the information, coordinates the hoisting system to adjust the overall posture and position of the steel truss girder, controls the temporary hinge device to realize flexible connection of the upper chord, and controls the fine adjustment device at the lower chord interface to automatically adjust the longitudinal position and the vertical elevation to ensure accurate closure; the local alignment auxiliary tool is used for solving the problem of difficulty in butt joint of individual rod pieces; the main cable transverse opposite-pulling system dynamically adjusts transverse deviation of the main cable, the stable structure in the hoisting process is guaranteed, all the systems work cooperatively, and efficient, safe and full-automatic alignment and hinging of the whole section of steel truss girder are achieved.

This application relates to a method and apparatus for measuring the lateral offset of a vehicle after a collision test. The method includes: folding and cutting test paper to obtain a first cut paper and a second cut paper to construct an offset measuring device; fixing the offset measuring device to the ground in the reverse direction of the left front wheel of the vehicle under test, and obtaining the pre-collision wheel imprint in the first cut paper during the reverse process; folding up the first cut paper and folding back the second cut paper to obtain the post-collision wheel imprint in the second cut paper after the collision test; and calculating the lateral offset of the vehicle under test after the collision test based on the pre-collision and post-collision wheel imprints. This application eliminates the need to place the measuring device in the collision deformation area. By comparing the actual collision test position with the theoretical collision position, the specific value of the offset at the collision position can be accurately measured, greatly reducing measurement costs and improving measurement efficiency.

A path planning system that calculates a laterally offset path based on a maximum allowable in-track lateral offset with respect to the center of a vehicle's host lane includes one or more controllers, which contain one or more processors that execute instructions to monitor perception data collected by multiple perception sensors until an offset event is detected that requires the vehicle to deviate from an original path. In response to the detection of the offset event, the one or more controllers calculate a non-linear error component of the maximum allowable in-track lateral offset.The one or more controllers update the vehicle's laterally offset path with the maximum permissible in-track lateral offset and apply a rate limiter to the maximum permissible in-track lateral offset in real time, while instructing the vehicle to travel along the laterally offset path.

Method (300) in a control unit (210) of a vehicle (101) for maintaining a formation (100) comprising a plurality of laterally offset vehicles (101, 102) to carry out a common mission on a surface, wherein the method (300) comprises the following steps: Determine (301) a lateral offset distance (150) of at least one other vehicle (102) in the formation (100) relative to the vehicle (101) using a sensor (140); and Adjusting (302) the lateral position of the vehicle (101) in relation to the other vehicle (102) when the specified (301) lateral offset distance (150) is outside a transverse threshold interval (160, 170).

Determining positioning of a sensor system associated with a vehicle involves: (i) identifying a given time when the vehicle was driving in a lane having substantially-straight lane geometry, (ii) inferring that, because the lane had substantially-straight lane geometry at the given time, the vehicle was laterally positioned in alignment with a lateral centerline of the lane at the given time, (iii) detecting a lane boundary of the lane in which the vehicle was driving at the given time, (iv) determining, at the given time, a first lateral distance between the lane boundary and the vehicle's associated sensor system and a second lateral distance between the lane boundary and the lateral centerline of the lane, and (v) based on the first and second lateral distances, determining a given measure of a lateral offset between the vehicle's associated sensor system and the lateral center of the vehicle for the given time.
