LANE CHANGE CONTROL ARRANGEMENT, A VEHICLE COMPRISING SUCH ARRANGEMENT AND A METHOD FOR CONTROLLING LANE CHANGES
First Claim
1. A lane change control arrangement for controlling lane changes for a host vehicle when the host vehicle drives in a first road lane of a road having two or more lanes, wherein the host vehicle includes at least one remote sensor arranged to determine whether a vehicle is present in a detectable zone of a second road lane adjacent to the first road lane, and a vehicle drive arrangement arranged to control at least one of steering and velocity of the host vehicle, the lane change control arrangement operable to:
- adjust, via the vehicle drive arrangement, the host vehicle velocity in accordance with a first velocity profile to expand the detectable zone to cover a previously undetectable zone of the second road lane;
detect, via the at least one sensor, whether a vehicle is present in the previously undetectable zone;
determine that a lane changeis possible using the second road lane upon having detected that no vehicle is present in the previously undetectable zone, oris unsuitable using the second road lane upon having detected that a vehicle is present in the previously undetectable zone and issue a control signal to the vehicle drive arrangement to adjust the host vehicle velocity in accordance with a second velocity profile until a safety distance is established between the host vehicle and the detected vehicle; and
issue a control signal to the vehicle drive arrangement to perform the lane change.

Abstract
A lane change control arrangement, vehicle, and method are described. The lane change control arrangement is arranged to adjust a host vehicle velocity in accordance with a first velocity profile to expand a detectable zone to cover a previously undetectable zone of a second road lane, detect whether a vehicle is present in the previously undetectable zone, determine that a lane change is possible, or determine that a lane change is unsuitable using the second road lane and issue a control signal to the vehicle drive arrangement to adjust the host vehicle velocity until a safety distance is established between the host vehicle and the detected vehicle, and issue a control signal to the vehicle drive arrangement to perform the lane change.

11. A method for controlling lane changes of a host vehicle having a lane change control arrangement arranged to control lane changes for the host vehicle when the host vehicle drives in a first road lane of a road having two or more lanes, wherein the host vehicle includes at least one remote sensor arranged to determine whether a vehicle is present in a detectable zone of a second road lane adjacent to the first road lane, and a vehicle drive arrangement arranged to control at least one of steering and velocity of the host vehicle, the method comprising:
-
adjusting, via the vehicle drive arrangement, the host vehicle velocity in accordance with a first velocity profile to expand the detectable zone to cover a previously undetectable zone of the second road lane; detecting, via the at least one sensor, whether a vehicle is present in the previously undetectable zone, determining that a lane change is possible using the second road lane upon having detected that no vehicle is present in the previously undetectable zone, or is unsuitable using the second road lane upon having detected that a vehicle is present in the previously undetectable zone and issuing a control signal to the vehicle drive arrangement to adjust the host vehicle velocity in accordance with a second velocity profile until a safety distance is established between the host vehicle and the detected vehicle; and issuing a control signal to the vehicle drive arrangement to perform the lane change.
