Towed vehicle braking apparatus
View Patent ↗An auxiliary braking system and method of controlling the braking a towed vehicle is provided that includes a remote control that is in selective communication with an auxiliary braking unit positioned in a towing vehicle. More specifically, it is often desirable for the operator of the towing vehicle to assess the performance of the auxiliary braking apparatus positioned in a towed vehicle. In addition, it is often advantageous for the operator to perform real time adjustments to the performance parameters of the auxiliary braking apparatus positioned in the towing vehicle without having to cease driving and physically access the auxiliary braking device.
1. An auxiliary braking system, comprising:
a circuit;
an actuator operably interconnected and controlled by the circuit;
a mechanism interconnected to the actuator and adapted for interconnection to a brake pedal of a towed vehicle; and
an activator when used only once causes the actuator to move more than once to deplete the vacuum reservoir of a braking system of the towed vehicle.
2. The auxiliary braking apparatus of claim 1 , wherein the actuator is a piston operably associated with a fluid reservoir.
3. The auxiliary braking system of claim 1 , further comprising an emergency braking switch that activates the actuator when the towing vehicle is spaced a predetermined distance from the towed vehicle, the auxiliary braking apparatus being inoperable if the emergency braking switch is not operatively associated with the auxiliary braking apparatus.
4. The auxiliary braking system of claim 1 , wherein the remote device includes at least one of a braking indicator, a brake sensitivity indicator, an indicator related to the status of the auxiliary braking apparatus, an indicator related to the position of the towed vehicle in relation to the towing vehicle, and an indicator related to the power level of the remote device.
5. The auxiliary braking system of claim 1 , wherein the auxiliary braking apparatus includes at least one of a normal operation indicator, low battery indicator, a compressor runtime indicator, an indication of an extension of the actuator, a reminder to bleed the brakes of the towed vehicle, an air pressure display, and a braking sensitivity indication.
6. The auxiliary braking system of claim 5 , wherein the at least one indicator is at least one of visual and audio.
7. The system of claim 1 , wherein depleting the vacuum reservoir of a braking system of the towed vehicle is automatic.
8. The system of claim 1 , wherein the activator is a start button wherein depressing the start button directs the actuator to selectively depresses the brake pedal of the towed vehicle a prerequisite amount of times to exhaust the brake vacuum in the towed vehicle.
9. The auxiliary braking system of claim 1 , wherein said auxiliary braking system does not operate unless the vacuum reservoir of the braking system is depleted.
10. The auxiliary braking system of claim 1 , wherein said auxiliary braking system does not operate unless the activator has been used.
11. The auxiliary braking system of claim 1 , wherein the circuit is capable of controlling selective braking logic and further comprising a remote device for positioning within a towing vehicle, the remote device having at least one indicator related to the performance of the auxiliary braking apparatus and the remote device being capable of selectively altering the braking logic.
12. The auxiliary braking system of claim 11 , wherein the braking logic is related to proportional braking and non-proportional braking and the remote device allows an operator to selectively switch from proportional braking, non-proportional braking, or a combination thereof.
13. The auxiliary braking system of claim 11 , wherein the braking logic is related to the sensitivity of the actuator.
14. A system for braking a towed vehicle comprising:
an actuating means adapted for interconnection to a brake pedal of the towed vehicle;
a control means in the towed vehicle operably interconnected to the actuating means; and
a manual system preparation interface in communication with the control means, the manual system preparation interface being activated once to direct the control means to selectively move the actuating means more than once.
15. The system of claim 14 , wherein the actuating means has an extension side and a retraction side that are in communication with one or more sensors.
16. The system of claim 14 , wherein the actuating means further comprises a compressor in fluidic communication with a reservoir.
17. The system of claim 14 , further comprising a means for releasing pressure in communication with the reservoir that is activated by at least one of automatically and manually.
18. The system of claim 14 , wherein the communicating means sends a signal to the control means for selectively positioning between proportional braking and non-proportional braking of the towed vehicle.
19. The system of claim 14 , wherein the system for braking a towed vehicle does not operate unless the manual preparation interface has been activated.
20. A system for braking a towed vehicle comprising:
an actuating means adapted for interconnection to a brake pedal of the towed vehicle;
a control means in the towed vehicle operably interconnected to the actuating means and for selectively operating the actuating means; and
an activator that moves the actuating means more than one times to deplete the vacuum reservoir of a braking system of the towed vehicle, and wherein said system for braking a towed vehicle does not operate unless the vacuum reservoir of the braking system is depleted.
21. The system of claim 20 wherein the activator actuates the actuating means a preselected number of times after a notification is sent that the vacuum reservoir of the towed vehicle's braking system has been recharged.
22. The system of claim 20 wherein the activator actuates the actuating means a preselected number of times when the vacuum reservoir of the towed vehicle's braking system has been recharged.
23. The system of claim 20 wherein the activator uses a preselected or varied input.
24. The system of claim 23 wherein the input is at least one of pressure, speed and timing.
25. The system of claim 20 , wherein the activator is a start button wherein depressing the start button directs the actuator means to selectively depresses the brake pedal of the towed vehicle a prerequisite amount of times to exhaust the brake vacuum in the towed vehicle.
26. The system of claim 20 , wherein depleting the vacuum reservoir of a braking system of the towed vehicle is automatic.
