Abstract

A trailer electronic braking system comprising a braking device capable of generating a braking force on a wheel on the trailer. The braking force is applied to the brake cylinders and is controllable by a braking ECU, which braking ECU is connected to a standards compliant communication bus on the trailer. The ECU is adapted to receive data inputs from sensors on the trailer. The system further includes an arrangement to interface to trailer electronics and a communications interface. In use, the arrangement transmits a request to the device for a driver to apply a predetermined condition to the trailer to enable control functions to be actuated from a remote device.

Claims

1. A trailer electronic braking system, comprising:

a braking device capable of generating a braking force on a wheel on the trailer, wherein a brake force into brake cylinders is controllable by a braking ECU, which braking ECU is connected to a standards compliant communication bus on the trailer and is adapted to receive data inputs from sensors on the trailer;

an interface arrangement to interface to trailer electronics and a communications interface, wherein to enable control functions to be actuated from a remote device, the interface arrangement transmits a request to the device for a driver to apply a predetermined condition to the trailer.

2. The trailer electronic braking system of claim 1, wherein the predetermined condition is a brake pressure to be applied by the driver.

3. The trailer electronic braking system of claim 1, where the trailer is first paired with the tractor prior to the request being transmitted.

4. The trailer electronic braking system of claim 1, wherein the interface arrangement includes a microcontroller.

5. The trailer electronic braking system of claim 1, further comprising:

a list of MAC addresses associated with at least one allowable further device, the braking system detecting the MAC address of the at least one allowable further device it detects such that it only pairs with an allowable MAC address.
