HITCH ANGLE WARNING SYSTEM AND METHOD |
摘要 |
A hitch angle warning system includes a camera-based hitch angle sensor that senses a hitch angle between a vehicle and a trailer. The hitch angle warning system also includes a controller that estimates an amount of time for the hitch angle to reach a threshold angle based on a rate of change of the hitch angle. The threshold angle may be set to a maximum hitch angle controllable by the vehicle based on a length of the trailer. The controller thereby generates a warning signal when the amount of time is less than a threshold time, which is configured to be greater or equal to than a response time of a driver of the vehicle to make a corrective action. The warning signal may be deactivated when the amount of time is greater than a second time that is greater than the threshold time. |

1. A hitch angle warning system, comprising:
a hitch angle sensor sensing a current hitch angle between a vehicle and a trailer; and a controller determining a future position of the trailer at a set time based on the current hitch angle and a speed of the vehicle and generating a warning signal when the future position exceeds a hitch angle threshold. |
