Abstract
A method and control unit in a vehicle for estimating a stretch of a road based on a set of tracks of another vehicle, when driving the vehicle along the road in a driving direction to a destination. The method comprises: detecting a set of tracks of the other vehicle, on the road; estimating the geographical position of the detected set of tracks; comparing the estimated geographical position of the detected set of tracks with map data; rejecting the detected set of tracks when it exits the road or when situated in a driving lane in a direction opposite to the driving direction; and otherwise estimating the stretch of the road based on the set of tracks.
Claims11
A method for operation in a vehicle for estimating a stretch of a road based on a set of tracks of another vehicle, when driving the vehicle along a road in a driving direction to a destination, said method comprising:
- detecting a set of tracks of the other vehicle, on the road;
- estimating a geographical position of the detected set of tracks;
- comparing the estimated geographical position of the detected set of tracks with map data;
- rejecting the detected set of tracks when it exits the road or when situated in a driving lane in a direction opposite to the driving direction;
- and
- otherwise estimating the stretch of the road based on the detected set of tracks of the other vehicle.
A control unit in a vehicle for estimating a stretch of a road based on a set of tracks of another vehicle when driving the vehicle along the road in a driving direction to a destination, wherein the control unit is configured to:
- detect the set of tracks of another vehicle on the road via a sensor;
- estimate a geographical position of the detected set of tracks;
- compare the estimated geographical position of the detected set of tracks with map data;
- reject the detected set of tracks when it exits the road or when situated in a driving lane in a direction opposite to the driving direction;
- and
- otherwise estimate the stretch of the road based on the detected set of tracks of the other vehicle.
A computer program product comprising program code stored on a non-transitory computer-readable medium, said computer program product for estimating a stretch of a road based on a set of tracks of another vehicle, when driving a vehicle along a road in a driving direction to a destination, wherein said computer program code comprises computer instructions to cause said at least one control unit to perform the following operations:
- detecting a set of tracks of the other vehicle on the road;
- estimating a geographical position of the detected set of tracks;
- comparing the estimated geographical position of the detected set of tracks with map data;
- rejecting the detected set of tracks when it exits the road or when situated in a driving lane in a direction opposite to the driving direction;
- and
- otherwise estimating the stretch of the road based on the detected set of tracks of the other vehicle.
A system for estimating a stretch of a road, based on a set of tracks of another vehicle when driving a vehicle along the road in a driving direction to a destination, wherein the system comprises:
- a sensor arranged on the vehicle;
- a positioning device for estimating the geographical position of the vehicle;
- a database comprising map data;
- and
- a control unit configured to:
- detecting a set of tracks of the other vehicle on the road;
- estimating a geographical position of the detected set of tracks;
- comparing the estimated geographical position of the detected set of tracks with map data;
- rejecting the detected set of tracks when it exits the road or when situated in a driving lane in a direction opposite to the driving direction;
- and
- otherwise estimating the stretch of the road based on the detected set of tracks of the other vehicle.
