MULTI-PIECE DASH MOUNT BRAKE CONTROLLER
A brake control unit includes an under dash unit and a dash mount unit. The dash mount unit is mounted to a dashboard of a vehicle and includes an accelerometer. The dash mount unit also includes a display and an input device. The under dash unit is positioned in another location of the vehicle and is communicatively coupled to the dash mount unit.
1 . A brake control unit for controlling brakes of a towed vehicle comprising:
a dash mount unit comprising:
a body comprising an accelerometer and a processor;
an input device extending from the body; and
a display device disposed within the input device; and
an under dash mount unit communicatively coupled to the dash mount unit and comprising a main control board,
wherein the under dash mount unit is separate from the body of the dash mount unit.
2 . The brake control unit of claim 1 , wherein the input device comprise a hollow shaft potentiometer.
3 . The brake control unit of claim 2 , wherein the input device further comprise the hollow shaft potentiometer and a control knob, and wherein the hollow shaft potentiometer is mounted with the control knob.
4 . The brake control unit of claim 3 , wherein the display device is positioned within the control knob.
5 . The brake control unit of claim 4 , wherein the display device comprises a dual 7-segment display.
6 . The brake control unit of claim 4 , wherein the control knob comprises a lens positioned in front of the display device.
7 . The brake control unit of claim 3 , wherein the control knob comprises a sensor that operatively detects a push of the control knob representing input from a user.
8 . The brake control unit of claim 3 , wherein the control knob comprises a sensor that operatively detects a turn of the control knob representing input from a user.
9 . The brake control unit of claim 1 , wherein the dash mount unit comprises a dash mount circuit board, and wherein the accelerometer, the processor, the display, and the input device are coupled to the dash mount circuit board.
10 . The brake control unit of claim 1 , wherein the dash mount unit is coupled to the under dash mount unit via at least one of a serial peripheral interface bus or an Inter-Integrated Circuit bus.
11 . The brake control unit of claim 1 , wherein the dash mount unit and the under dash mount unit communicate via an encoded pulse width modulated signal.
12 . The brake control unit of claim 1 , wherein the main control board comprises a power circuit that operatively sends power to trailer brakes.
13 . The brake control unit of claim 12 , wherein the power circuit comprises a main MOSFET and a power MOSFET in series with the main MOSFET.
14 . The brake control unit of claim 13 , wherein the power MOSFET is switched to an off condition in response to detection of a short, improper connection, or improper gate voltage.
15 . A brake control unit comprising:
a dash mount unit comprising:
a body comprising an accelerometer and a processor;
an input device comprising a hollow shaft potentiometer and a control knob extending from the body, wherein the control knob is rotatable; and
a display device disposed within the control knob; and
an under dash mount unit communicatively coupled to the dash mount unit and comprising a main control board,
wherein the under dash mount unit is separate from the body of the dash mount unit, and
wherein the display device maintains its orientation while the control knob is operatively rotated.
16 . The brake control unit of claim 15 , wherein the under dash mount unit is operatively installable in any orientation.
17 . A brake control unit comprising:
a dash mount unit comprising:
a body comprising an accelerometer and a processor;
an input device comprising a hollow shaft potentiometer and a control knob extending from the body, wherein the control knob is rotatable; and
a display device disposed within the control knob; and
an under dash mount unit communicatively coupled to the dash mount unit and comprising a main control board,
wherein the main control board comprises a power circuit that operatively sends a control signal to brakes of a towed vehicle, and wherein the main control board determines whether the main control board and the body are in operative communication.
18 . The brake controller of claim 17 , wherein the main control board sends the control signal is a proportional control signal when the main control board determines that the main control board and the body are in operative communication.
19 . The brake controller of claim 17 , wherein the main control board sends the control signal is a predetermined ramping control signal when the main control board determines that the main control board and the body are not in operative communication.
20 . The brake controller of claim 17 , wherein at least one of the dash mount unit or under dash mount unit operatively enter a sleep mode in response to at least one of a passage of time where manual braking is not activated, gain adjustments are not activated, boost adjustments are not activated, a stoplight is not activated, or an accelerometer readings is inactive.
21 . The brake controller of claim 20 , wherein at least one of the dash mount unit or under dash mount unit operatively exits the sleep mode upon activation of manual braking, gain adjustments, boost adjustments, stoplight activation, or accelerometer readings.
