The present disclosure relates to a control system for selectively controlling a vehicle, ensuring high integrity of decisions taken by the control system when controlling the vehicle. The present disclosure also relates to a corresponding computer implemented method and to a computer program product.

Control system for a vehicle

The present disclosure relates to a computer implemented method for operating an autonomous vehicle based on sensor data representative of an area in a driving direction of and in the vicinity of the vehicle. The vehicle is equipped with a control unit adapted to determine if a plurality of detailed actions to be performed by the vehicle successfully may be used for fulfilling a desired general action plan for the vehicle. The present disclosure also relates to a corresponding control system and to a computer program product.

Method for operating an autonomous vehicle

A method for planning a driving trajectory defining a travelling path for a vehicle, wherein the driving trajectory is intended to be followed by executing one or more vehicle manoeuvres and wherein the vehicle comprises at least one environment perception sensor having a sensor field of view he method includes planning the driving trajectory from a first point to a second point, by including at least one additional vehicle manoeuvre resulting in a deviation from an otherwise expected travelling path from the first point to the second point, so that each section of an area which the vehicle is intended to pass from the first point to the second point is covered in the sensor field of view at least one time during driving from the first point to the second point and at least before passing each respective section.

Method for planning a driving trajectory defining a travelling path for a vehicle

The present disclosure relates to a computer implemented method for determining a reliability level of data received by an ego vehicle from a target vehicle being different from the ego vehicle. The present disclosure also relates to a corresponding control system and to a computer program product.

Method for determining reliability of received data

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

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

The invention relates to a method for diagnosing error of at least one of an ego vehicle () and a surrounding vehicle (), which method comprises the steps of: the ego vehicle () receiving (S) sensor data about the surrounding vehicle () from an on-board sensor () of the ego vehicle () and vehicle to vehicle data from the surrounding vehicle (); the ego vehicle () comparing (S) the received sensor data and the received vehicle to vehicle data; and the ego vehicle () detecting (S) a difference between the received sensor data and the received vehicle to vehicle data, whereby the ego vehicle (): stops (S) receiving vehicle to vehicle data from the surrounding vehicle (); registers (S) a potential error of the ego vehicle (); and reports (S) a potential error of the surrounding vehicle () to at least one of the surrounding vehicle () and a remote server (). The invention also concerns a method for diagnosing error of a surrounding vehicle ().

Methods for diagnosing error of an ego vehicle and/or a surrounding vehicle

The invention relates to a method for a string comprising a plurality of vehicles platooning by means of vehicle-to-vehicle (V2V) communication, comprising collecting (S) from a plurality of sources () values (OP-OP) of operational parameters related to the operation of a first () of the vehicles, characterized by determining (S) based on the operational parameter values (OP-OP) a plurality of values (AP-AP) of an acceleration parameter indicative of an acceleration of the first vehicle, and selecting (S) from the acceleration parameter values (AP-AP) an extreme value (AP) indicative of the lowest acceleration of the first vehicle ().

Method for controlling the braking of a following vehicle of a string comprising a plurality of platooning vehicles

The invention relates to a method for controlling a subject vehicle () travelling along a road behind a vehicle transmitting wireless signals representative of at least one parameter affecting the velocity and/or acceleration of the transmitting vehicle (), the method comprising&#x2014;receiving said wireless signals from the transmitting vehicle (), &#x2014;controlling (S) the velocity and/or acceleration of the subject vehicle () in dependence on the received signals, &#x2014;during said control (S) in dependence on the received signals, monitoring (S) by means () other than means for wireless communication a distance (DSF) between the subject vehicle () and a further vehicle () travelling between the subject vehicle () and the transmitting vehicle (), &#x2014;and determining in dependence on the monitoring of the distance (DSF) between the subject vehicle () and the further vehicle () whether or not to control (S) the velocity and/or acceleration of the subject vehicle () in dependence on the monitored distance (DSF).

Method for controlling a vehicle

A method is provided for vehicle identification, which method includes the steps of: an ego vehicle detecting a communicating vehicle by wireless vehicle to vehicle communication; the ego vehicle detecting a nearby vehicle by a sensor onboard the ego vehicle; the ego vehicle sending an identification request to the communicating vehicle by wireless vehicle to vehicle communication, wherein the identification request instructs the communicating vehicle to perform an action; the ego vehicle determining whether or not the nearby vehicle performed the action based at least on data from the sensor; and if the ego vehicle determines that the nearby vehicle performed the action, the ego vehicle determining that the communicating vehicle and the nearby vehicle are the same vehicle.
