Abstract
A system and method of detecting a vehicle trailer. The method includes sensing a first vehicle condition that indicates a movement of the vehicle, and sensing a second vehicle condition that indicates an angle of the vehicle. The method also includes determining a disturbance from the movement and the angle of the vehicle, and detecting a trailer presence when the determined disturbance is above a threshold.
Claims36
A method of detecting a vehicle trailer adapted to be connected at a hitch of a towing vehicle, the method comprising:
- sensing a first vehicle condition indicative of a movement of the towing vehicle;
- sensing a second vehicle condition indicative of an angle of the towing vehicle;
- determining a disturbance at the hitch based on data including at least the movement of the vehicle and the angle of the vehicle;
- and
- detecting a trailer presence when the determined disturbance at the hitch is above a threshold.
A system for detecting a vehicle trailer adapted to be connected at a hitch of a towing vehicle, the system comprising:
- a plurality of sensors configured to sense respective vehicle conditions, the conditions including a movement and a speed of the towing vehicle;
- an estimator configured to estimate a disturbance at the hitch based on data including at least the movement of the towing vehicle and the speed of the towing vehicle;
- and
- a detector configured to detect a trailer presence when the estimated disturbance at the hitch is above a threshold.
A method of detecting a vehicle trailer adapted to be connected at a hitch of a towing vehicle, the method comprising:
- modeling a plurality of dynamics of the towing vehicle;
- determining a plurality of hitch force values from the modeled dynamics of the towing vehicle;
- summing the determined hitch force values;
- and
- detecting a trailer presence when the sum of the hitch force values exceeds a threshold.
A system for detecting a vehicle trailer adapted to be connected at a hitch of a towing vehicle, the system comprising:
- means for modeling a plurality of dynamics of the towing vehicle;
- means for determining a plurality of hitch force values based at least in part on the modeled dynamics;
- means for determining a sum of the determined hitch force values;
- and
- means for detecting a trailer presence when the sum exceeds a threshold.
