Abstract

The present invention comprises a brake release system for a towed vehicle. The towed vehicle has a braking device that is positioned within the towed vehicle and is configured to depress a brake pedal of the towed vehicle. The braking device includes a brake actuator that is configured to controllably press on the towed vehicle'"'"'s brake pedal. The brake release system is in communication with the brake actuator. The brake release system is configured to monitor when the brake pedal has been depressed for a predetermined period of time and when the brake release system determines that the predetermined period of time has been exceeded; the brake release system deactivates the brake actuator.

Claims

1. A braking device for a towed vehicle, the braking device being configured to be positioned within the towed vehicle, the braking device further being configured to depress a brake pedal of the towed vehicle, the braking device comprising:

(A) a brake actuator, the brake actuator configured to controllably press on the towed vehicle'"'"'s brake pedal, the brake actuator comprising a brake pedal attachment device, the brake pedal attachment device being removably attached to the brake pedal;

(B) a brake release system in communication with the brake actuator, the brake release system being configured to monitor when the brake pedal has been depressed for a predetermined period of time and wherein when the brake release system determines that the predetermined period of time has been exceeded, the brake release system deactivates the brake actuator.

2. The braking device of claim 1, further comprising a controller in communication with the brake release system and the brake actuator, the controller being configured to control the brake actuator.

3. The braking device of claim 1, wherein the brake release system further comprises:

(A) a timing circuit in communication with a brake light switch, the timing circuit configured to determine if the brake pedal has been depressed for the predetermined period of time;

(B) a relay circuit in communication with a power supply and the timing circuit, the relay circuit configured to disconnect the power supply circuit, if the predetermined period of time has been exceeded.

4. The braking device of claim 1, wherein the brake release system further comprises:

(A) a timing circuit in communication with a brake light switch, the timing circuit configured to determine if the brake pedal has been depressed for the predetermined period of time;

(B) a switching circuit in communication with an air release valve and the timing circuit, the switching circuit configured to open the air release valve, if the predetermined period of time has been exceeded.

5. The braking device of claim 1, wherein the brake release system is further in communication with a breakaway device, wherein if the breakaway device is activated, the brake release system is deactivated.

6. The braking device of claim 1, wherein the brake release system is further in communication with a test button for testing the brake release system.

7. The braking device of claim 1, wherein the predetermined period of time is about 17 seconds.

8. The braking device of claim 1, wherein the brake release system is further in communication with a pressure switch.

9. A braking system for a towed vehicle comprising:

(A) braking means for depressing a brake pedal of the towed vehicle;

(B) brake release means for deactivating the braking means, the brake release means in communication with the braking means, the brake release means being configured to monitor when the brake pedal has been depressed for the predetermined period of time and to deactivate the braking means after the predetermined period of time has transpired.

10. The braking system of claim 9, further comprising a controller in communication with the brake release means and the braking means.

11. The braking system of claim 9, wherein the brake release means further comprises:

(A) a timing circuit in communication with a brake light switch, the timing circuit configured to determine if the brake pedal has been depressed for the predetermined period of time;

(B) a relay circuit in communication with a power supply and the timing circuit, the relay circuit configured to disconnect the power supply circuit, if the predetermined period of time has been exceeded.

12. The braking system of claim 9, wherein the brake release means further comprises:

(A) a timing circuit in communication with a brake light switch, the timing circuit configured to determine if the brake pedal has been depressed for the predetermined period of time;

(B) a switching circuit in communication with an air release valve and the timing circuit, the switching circuit configured to open the air release valve, if the predetermined period of time has been exceeded.

13. The braking system of claim 9, wherein the brake release means is further in communication with a breakaway device, wherein if the breakaway device is activated, the brake release means is deactivated.

14. The braking system of claim 9, wherein the brake release means is further in communication with a test button for testing the braking system.

15. The braking system of claim 9, wherein the predetermined period of time is approximately 17 seconds.

16. The braking system of claim 9, wherein the brake release means is further in communication with a pressure switch.

17. The braking system of claim 9, wherein a display means is in communication with the brake release means, the display means being adapted to communicate that braking means have been deactivated.

18. A method of monitoring a braking system of a towed vehicle, the braking system being configured to brake the towed vehicle, the method comprising:

(A) sensing the application of braking to the towed vehicle;

(B) measuring a period of time that the brakes are applied;

(C) deactivating the braking system, if the period of time that the brakes are applied is greater than a predetermined period of time.

19. The method of claim 18, wherein the braking system is activated if a breakaway condition occurs.

20. The method of claim 18, wherein the braking system is deactivated by removing power to the braking system.

21. The method of claim 18, wherein the braking system is deactivated by removing air pressure from the braking system.

22. The method of claim 18, further comprising displaying that the braking system is deactivated.
