Abstract

A system for detecting if a hitch connecting a trailer and a vehicle is not secure. The system comprises a sensor, an output device, and electronic control unit. The electronic control unit receives information about the hitch connecting the trailer and the vehicle from the sensor. The electronic control unit detects if the hitch connecting the trailer and the vehicle is not secure. If the hitch connecting the trailer and the vehicle is not secure the electronic control unit generates a driver notification and controls the vehicle'"'"'s motion.

Claims

1. A system for detecting if a hitch connecting a trailer and a vehicle is not secure, the system comprising;

a sensor;

an output device; and

an electronic control unit configured to,

receive from the sensor, information about the hitch connecting the trailer and the vehicle;

detect if the hitch connecting the trailer and the vehicle is not secure;

generate a driver notification;

control a motion of the vehicle upon detecting the hitch connecting the trailer and the vehicle is not secure.

2. The system according to claim 1, wherein the electronic control unit is configured to detect if the hitch connecting the trailer and the vehicle is not secure by,

detecting if trailer chains are crossed and connected to the trailer and the vehicle,

detecting if a trailer coupler is in a latched position,

detecting if a trailer coupler latch pin is in place, and

detecting if a trailer jack or a trailer tongue wheel is retracted.

3. The system according to claim 2, wherein the electronic control unit detects if the hitch connecting the trailer and the vehicle is secure using neural network classifiers.

4. The system according to claim 3, wherein input received by the electronic control unit via a user interface is used to modify the neural network classifiers.

5. The system according to claim 2, wherein results of detecting if the hitch connecting the trailer and the vehicle is not secure are displayed via a user interface.

6. The system according to claim 1, wherein the driver notification is an audio or visual notification, such as a light on a heads up display or a beeping alarm.

7. The system according to claim 1, wherein the sensor is a video camera or an ultrasonic sensor.

8. A method for detecting if a hitch connecting a trailer and a vehicle is not secure, the method comprising;

receiving, from a sensor, information about the hitch connecting the trailer and the vehicle;

detecting, with an electronic control unit, if the hitch connecting the trailer and the vehicle is not secure;

generating, with the electronic control unit, a driver notification;

controlling, with the electronic control unit, a motion of the vehicle upon detecting the hitch connecting the trailer and the vehicle is not secure; and

outputting, with an output device, the driver notification.

9. The method according to claim 8, wherein detecting, with the electronic control unit, if the hitch connecting the trailer and the vehicle is not secure comprises,

detecting if trailer chains are crossed and connected to the trailer and the vehicle,

detecting if a trailer coupler is in a latched position,

detecting if a trailer coupler latch pin is in place, and

detecting if a trailer jack or a trailer tongue wheel is retracted.

10. The method according to claim 9, wherein the electronic control unit detects if the hitch connecting the trailer and the vehicle is secure using neural network classifiers.

11. The method according to claim 10, wherein input received via a user interface is used to improve the neural network classifiers.

12. The method according to claim 9, wherein results of detecting if the hitch connecting the trailer and the vehicle is not secure are displayed via a user interface.

13. The method according to claim 8, wherein the driver notification is an audio or visual notification, such as a light on a heads up display or a beeping alarm.

14. The method according to claim 8, wherein the sensor is a video camera or an ultrasonic sensor.
