The invention relates to a method for a string comprising a plurality of vehicles, including a lead vehicle and at least one follower vehicle, comprising the follower vehicle following, by means of vehicle-to-vehicle communication, the lead vehicle in a follower trajectory. The method comprises generating surroundings data, regarding the surroundings of at least a part of the string, generating, using the surroundings data, a backup trajectory, which is different from the follower trajectory, wherein the generated backup trajectory, or the surroundings data, is received by at least one of the at least one follower vehicle, wherein the receiving follower vehicle follows the generated backup trajectory, upon a determination of a predetermined condition for following the generated backup trajectory.

Method for controlling a string of vehicles

Embodiments of the invention pertain to a method of controlling a remotely operated vehicle operated from a remote operation station via a communication link, the method comprising: monitoring a latency (L) of the communication link, requesting (S) an emergency stop maneuver in response to the latency exceeding a predetermined threshold (T), and cancelling (S) the requested emergency stop maneuver, in response to the communication link being recovered within a brake reaction time (A). Embodiments of the invention also relate to a remotely operated vehicle having a control unit configured to: monitor a latency (L) of a communication link between the vehicle and a remote operation station, request an emergency stop maneuver in response to the latency exceeding a predetermined threshold (T), and cancel the requested emergency stop maneuver, in response to the communication link being recovered within a brake reaction time period (A).

Method for controlling a remotely operated vehicle

The present disclosure relates to an electronic arrangement (), generally adapted to determine a movement. Specifically, the electronic arrangement is arranged to determine and handle an error drift related to signals received from plurality of satellites () arranged in communication with the electronic arrangement, and to determine a thereto related error corrected movement. The present disclosure also relates to a corresponding method and to a computer program product.

Electronic arrangement for determining a movement

A method for estimating the attitude of a vehicle by using a global navigation satellite system having a plurality of satellites, wherein the vehicle comprises at least a first antenna and a second antenna having a separation to each other, comprising the steps of: detecting an outage of said global navigation satellite system; starting a dead-reckoning algorithm in order to extrapolate a change in attitude during the outage of said global navigation satellite system obtaining a dead-reckoned attitude; detecting that said global navigation satellite system has recovered, in particular via the availability of carrier phase observables and calculating a new attitude using the recovered global navigation satellite system by incorporating the obtained dead-reckoned attitude as a starting condition.

Method for estimating the attitude of a vehicle

The invention relates to a method for a follower vehicle () following a lead vehicle, comprising&#x2014;determining a position (PL) and a heading (HL) of the lead vehicle (), &#x2014;determining a position (PF) and a heading (HF) of the follower vehicle (), &#x2014;subsequently establishing a path for the follower vehicle () by fitting a curve (C) to said positions (PL, PF) and said headings (HL, HF), &#x2014;and controlling the follower vehicle () so as to move along the established path.

Method for establishing a path for a vehicle

A method for a follower vehicle following a lead vehicle, comprising establishing, in a first control mode of the follower vehicle, a path for the follower vehicle to follow the lead vehicle, characterized by
