  • Publication number: 20220340111
    Abstract: A brake system for a trailer has first and second pneumatic circuits for supplying air pressure to the wheel ends on the trailer. The air pressure to brake devices at the wheel ends is controllable via a first brake ECU. First and second pressure control valves control pressure from the pneumatic circuits to the respective wheel ends. The system further has a second ECU adapted to electrically control the actuation of the pressure control valves.

  • Publication number: 20220219663
    Abstract: A brake system is provided for a trailer vehicle having a plurality of axles, each of which has a wheel end on a respective side of the vehicle, the brake system including first and second pneumatic circuits for supplying air pressure to brake devices at the wheel ends. The system includes a spring brake modulator valve arrangement adapted to control pressure to spring brakes on the vehicle, which modulator valve arrangement receives an input from at least one of the pneumatic circuits and a control pressure from the trailer brake module. Flow of air to the brakes is controllable either by the trailer brake module or by the spring brake modulator valve arrangement to provide redundancy.

  • Patent number: 9260078
    Abstract: A trailer electronic braking system includes a braking device capable of generating a braking force on a wheel on the trailer, a brake force into the brake cylinders being controllable by a braking ECU. The braking ECU is connected to a standards compliant communication bus on said trailer and is adapted to receive data inputs from sensors on the trailer. An interface to trailer electronics and a communications interface are also provided. The brake system is further adapted to transmit a trailer identifier such as an SSID, such that the trailer identifier can be paired with a further device, such as a mobile telephone associated with a tractor driver, the further device having previously been provided with the trailer identifier.

An access point adapted to receive inputs from further sensors on the trailer and/or to read the inputs from sensors received by the braking ECU such that data received from the sensors can be rendered in standards compliant manner and wirelessly transmitted to a further device such as a mobile telephone remote or distinct from the trailer. The further device is adapted to display information so received using a standards compliant client such as with a web browser.
