Abstract
A method of selecting a location of a tracking point for a vehicle unit of a vehicle includes dynamically adapting the location of the tracking point based on a vehicle speed. In some examples, the location of the tracking point for a relatively high speed is located (along the vehicle unit) in front of the location of the tracking point for a relatively low speed. Also disclosed is a method of determining a reference location of the tracking point for a reference speed. The method comprises evaluating vehicle motion behavior for a plurality of candidate locations of the tracking point, and selecting one of the candidate locations as the reference location based on vehicle motion behavior metric values acquired through the evaluation.
Claims17
A computer system comprising processing circuitry configured to select a location of a tracking point for a vehicle unit of a vehicle by:
- dynamically adapting the location of the tracking point based on a vehicle speed,
- wherein the vehicle unit has a front end and a rear end, with a vehicle unit longitudinal direction defined from the rear end towards the front end, and wherein dynamically adapting the location of the tracking point based on the vehicle speed comprises:
- selecting a first location of the tracking point for a first vehicle speed and a second location of the tracking point for a second vehicle speed, wherein a direction from the second location towards the first location coincides with the vehicle unit longitudinal direction responsive to the first vehicle speed being higher than the second vehicle speed.
A computer system comprising processing circuitry configured to determine, for a reference speed, a reference location of a tracking point for a vehicle unit of a vehicle by:
- evaluating vehicle motion behavior to acquire vehicle motion behavior metric values for a plurality of candidate locations of the tracking point,
- selecting one of the candidate locations as the reference location based on the vehicle motion behavior metric values;
- and
- wherein the selected candidate location corresponds to a minimum or maximum vehicle motion behavior metric value among the candidate locations of the plurality.
A computer-implemented method of selecting a location of a tracking point for a vehicle unit of a vehicle, the method comprising:
- dynamically adapting, by processing circuitry of a computer system, the location of the tracking point based on a vehicle speed,
- wherein the vehicle unit has a front end and a rear end, with a vehicle unit longitudinal direction defined from the rear end towards the front end, and wherein dynamically adapting the location of the tracking point based on the vehicle speed comprises:
- selecting a first location of the tracking point for a first vehicle speed and a second location of the tracking point for a second vehicle speed, wherein a direction from the second location towards the first location coincides with the vehicle unit longitudinal direction responsive to the first vehicle speed being higher than the second vehicle speed.
A computer-implemented method of determining, for a reference speed, a reference location of a tracking point for a vehicle unit of a vehicle, the method comprising:
- evaluating vehicle motion behavior to acquire vehicle motion behavior metric values for a plurality of candidate locations of the tracking point,
- selecting one of the candidate locations as the reference location based on the vehicle motion behavior metric values;
- and
- wherein the selected candidate location corresponds to a minimum or maximum vehicle motion behavior metric value among the candidate locations of the plurality.
