Abstract: When a trailer is pulled by a tow vehicle where the trailer begins to sway to the left and right of the tow vehicle a large sway can result in loss of control of the trailer and or tow vehicle. The field of the present invention is a system and method of controlling a trailer sway which comprises determining the sway of the trailer utilizing an electronic sensor and independently applying the left or right trailer brakes at varying levels to reduce trailer sway. The traditional single braking signal power from the tow vehicle is separated into two independent braking signals for each of the left and right brakes. All brakes are applied whenever the traditional braking signal goes active where trailer battery power is utilized to independently activate the left and or right brakes during trailer sway.

Abstract: An electric-hydraulic antilock braking system (ABS) installed in a trailer is coupled with a tow vehicle to facilitate controlled braking of the trailer. A trailer in-cab controller (TIC) monitors vehicle networks for diagnostic information used in determining appropriate braking actions to be taken. A communication network can interconnect the TIC, a trailer actuator controller (TAC), and an ABS controller. The ABS controller receives current tow vehicle speeds and current trailer wheel speeds, and dynamically adjusts the brakes based on the differences in the speeds. A three-way solenoid valve or an equivalent valve structure thereto allows for the ABS system to be quickly activated and deactivated.

Abstract: An anti-lock braking system includes a sensor apparatus that includes a sensor body. In a first position, the sensor body is positioned such that a desired gap is maintained between the sensor body and a reference point located on a tone ring, which is rotatably coupled to a corresponding wheel hub. In the first position, a spring-loaded plunger holds the sensor body in place. When the sensor body is moved to a second position, a plunger pin is displaced within the plunger, putting tension on an internal spring. The tension in the spring returns the sensor body to the first position.

Abstract: An apparatus and method for binary communication between a vehicle and a trailer transmits high voltage and low voltage signals detectable as high bits and low bits aggregated into messages. A controller in the vehicle and trailer subsystems each include transceivers for transmitting messages across the vehicle's powerbus that are detectable when current flows across the powerbus. The apparatus and method are useful for controlling trailer brakes via a blue wire interface.
