A method performed by a control unit for operating an autonomous vehicle is provided. The control unit is arranged to communicate via at least one antenna. The control unit obtains, based on a signal from the at least one antenna, information relating to at least one geographical zone associated with a transponder as the autonomous vehicle moves in proximity of the transponder. Also, the control unit determines an autonomous operating mode of the autonomous vehicle based on the obtained information relating to the at least one geographical zone associated with the transponder. The control unit further operates the autonomous vehicle in accordance with the determined autonomous operating mode.

Control unit and method therein for operating an autonomous vehicle

A method of verifying a position of a vehicle using a vehicle-mounted device, the method including generating first position data for the vehicle-mounted device responsive to receiving data from a transponder-based localization system, generating second position data for the vehicle-mounted device responsive to receiving data from another localization system; and reporting verified vehicle position data for the vehicle, based on a comparison of the data from the other localization system with the data from the transponder-based localization system for the vehicle-mounted device.

Vehicle localization system

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 assessing reliability of a brake assembly of a vehicle. The brake assembly comprises brake system, nominal automation system and safety system. The brake system is adapted to receive a brake request individually from each one of the nominal automation system and the safety system and in response, initiate a braking operation. The method comprises determining an actual braking operation density, the actual braking operation density determined on the basis of at least a subset of occurrences per unit time when a braking operation is initiated by the brake system; in response to detecting that the actual braking operation density is lower than a braking operation reference density, issuing a brake request from the safety system; detecting a response of the brake system to the signal issued from the safety system, and on the basis of at least the detected response, assessing the reliability of the brake assembly.

A method performed by a central unit for evaluating a performance of an obstacle detection system comprised in a first object within a set of two or more objects at a confined area. The first object is a vehicle. The central unit obtains pose data from each object in the set and obstacle detection data from at least the first object. The central unit determines a relative pose of the objects using the pose data from each object. The central unit the obstacle detection data from each object in the set to the determined relative pose of the objects. Based on the comparison, the central unit evaluates the performance of the obstacle detection system of the first object.

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.
