  • Trailer brake system
    Patent number: 10894534
    Abstract: The disclosure provides a trailer brake system that includes a sensor system and a brake control unit. The sensor system is supported by a trailer and includes at least one wheel speed sensor associated with each wheel of the trailer. The brake control unit is supported by the trailer and is in communication with a tow vehicle configured to tow the trailer. The brake control unit is configured to: receive sensor data from the sensor system, and receive a brake signal from the tow vehicle indicative of a driver pressing a brake pedal of the tow vehicle. The brake control unit is also configured to: determine, for each brake, a hydraulic pressure based on the sensor data and the brake signal; and apply pressure by way of brake lines to the brake associated with each wheel, based on the hydraulic pressure.
