Abstract

An autonomous vehicle, an overtake assessment arrangement, and an overtake assessment system are provided. The overtake assessment arrangement is configured to receive, from at least one external source, real time traffic information on one or more surrounding vehicles outside a sensor monitoring area, assess whether to overtake at least one preceding vehicle within the sensor monitoring area or not, based on the real time traffic information received via the communication unit, and provide a vehicle drive arrangement with input indicative of the assessment, such that the vehicle drive arrangement is able to control the host vehicle to overtake the at least one preceding vehicle or not in accordance with the input.

Claims

1. An overtake assessment arrangement configured to assess potential overtake scenarios during drive of an autonomous host vehicle, the host vehicle comprising at least one sensor arranged to monitor a sensor monitoring area of a vehicle surrounding, a vehicle drive arrangement configured to control steering and velocity of the host vehicle at least partly based on information received from the at least one sensor, and a communication unit, the overtake assessment arrangement comprising:

a processing unit configured to

receive via the communication unit, from at least one external source, real time traffic information on one or more surrounding vehicles outside the sensor monitoring area,

assess whether to overtake at least one preceding vehicle within the sensor monitoring area or not, based on the real time traffic information received via the communication unit, and

provide the vehicle drive arrangement with input indicative of the assessment;

wherein the overtake assessment arrangement is configured to provide input to the vehicle drive arrangement such that the vehicle drive arrangement is able to control the host vehicle to overtake the at least one preceding vehicle or not in accordance with the input.

2. The overtake assessment arrangement according to claim 1 wherein the overtake assessment arrangement via the communication unit is configured to receive, from at least one remote server, real time traffic information on at least one surrounding vehicle outside the sensor monitoring area, the real time traffic information being related to at least one of a velocity, lane selection and a heading of the at least one surrounding vehicle.

3. The overtake assessment arrangement according to claim 1 wherein the overtake assessment arrangement via the communication unit is configured to receive, from at least one surrounding vehicle or communication equipment associated with the at least one surrounding vehicle, real time traffic information on the at least one surrounding vehicle outside the sensor monitoring area, the real time traffic information being related to at least one of a velocity, lane selection and a heading of the at least one surrounding vehicle.

4. The overtake assessment arrangement according to claim 1 wherein the overtake assessment arrangement via the communication unit is configured to receive, from at least one roadside unit, real time traffic information on the at least one surrounding vehicle outside the sensor monitoring area, the real time traffic information being related to at least one of a velocity, lane selection and a heading of the at least one surrounding vehicle.

5. The overtake assessment arrangement according to claim 1 wherein the overtake assessment arrangement is connectable to a navigation system comprised in the host vehicle, to which navigation system a user is allowed to input a preferred host vehicle driving route, and that the overtake assessment arrangement via the communication unit is configured to receive real time traffic information related to at least one of a velocity, lane selection and a heading of at least one surrounding vehicle driving along the host vehicle driving route.

6. The overtake assessment arrangement according to claim 5 wherein the overtake assessment arrangement via the communication unit is configured to receive real time traffic information related to at least one of a velocity, lane selection and a heading of a plurality of surrounding vehicles driving along the host vehicle driving route, and that the processing unit is arranged to assess whether to overtake at least one preceding vehicle or not, by providing the drive arrangement with input indicative of a host vehicle lane selection.

7. The overtake assessment arrangement according to claim 1 wherein the overtake assessment arrangement via the communication unit is configured to send, to at least one external source, real time traffic information related to at least one of a velocity, lane selection and host vehicle driving route for the host vehicle.

8. The overtake assessment arrangement according to claim 1 wherein the overtake assessment arrangement via the communication unit is configured to receive, from at least one external source, real time traffic information gathered on a plurality of surrounding vehicles driving along the host vehicle driving route and that the processing unit is arranged to assess whether to overtake at least one preceding vehicle or not based on the real time traffic information received via the communication unit.

9. The overtake assessment arrangement according to claim 1 wherein the at least one sensor in the autonomous host vehicle is configured to detect a velocity of at least one preceding vehicle, the overtake assessment arrangement via the communication unit is configured to receive, from at least one external source, information on real time velocity for at least one surrounding vehicle outside the sensor monitoring area, and the processing unit is configured to provide the drive arrangement with input indicative of an overtake of the at least one preceding vehicle only if the velocity of the at least one surrounding vehicle outside the sensor monitoring area exceeds the velocity of the at least one preceding vehicle with a threshold velocity, such that the vehicle drive arrangement is able to, in a potential overtake scenario, control the host vehicle to overtake the at least one preceding vehicle in accordance with the input.

10. The overtake assessment arrangement according to claim 1 wherein the at least one sensor in the autonomous host vehicle is configured to detect a velocity of at least one preceding vehicle, the overtake assessment arrangement via the communication unit is configured to receive, from at least one external source, information on real time velocity for a plurality of surrounding vehicles outside the sensor monitoring area, and the processing unit is configured to provide the drive arrangement with input indicative of non-initiation of an overtake of the at least one preceding vehicle if a plurality of relative velocities between the at least one preceding vehicle and the plurality of surrounding vehicles outside the sensor monitoring area all are below a threshold velocity, such that the vehicle drive arrangement is able to, in a potential overtake scenario, control the host vehicle not to initiate an overtake of the at least one preceding vehicle in accordance with the input.

11. An autonomous vehicle comprising an overtake assessment arrangement according to claim 1.

12. An overtake assessment system comprising a plurality of autonomous vehicles, each vehicle equipped with an overtake assessment arrangement according to claim 1.
