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.

Claims

1. A trailer electronic braking system, comprising:

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 an electropneumatic braking pressure control module, wherein the electropneumatic braking pressure control module is connected to a standards compliant communication bus on the trailer and is adapted to receive data inputs from sensors on the trailer; and

an interface arrangement to interface trailer electronics and a communications interface, the communications interface having a wireless device configured to transmit a trailer identifier, which includes a service set identifier (SSID), for enabling pairing with a further device receiving the trailer identifier.

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

3. The trailer electronic braking system of claim 1, wherein the wireless card includes an 802.11 wireless card, which is adapted to transmit the SSID, the trailer identifier including the SSID.

4. The trailer electronic braking system of claim 1, wherein the trailer electronic braking system is provided with a list of MAC addresses associated with allowable further devices, and wherein the braking system detects the MAC address of any further devices it detects such that it only pairs with an allowable MAC address.

5. The trailer electronic braking system of claim 1, wherein the further device is provided with parking brake releases codes, which codes can be transmitted to the electropneumatic braking pressure control module after pairing to release the parking brake.

6. The trailer electronic braking system of claim 1, wherein the road train includes two or more trailers, at least two of which trailers are adapted to transmit the trailer identifier for each of the trailers, wherein a first trailer for connection to a tractor or prime mover is adapted to request or detect the trailer identifier of another trailer, wherein if the trailer identifier is associated with the road train, and wherein the first trailer instructs the second trailer to stop transmitting the trailer identifier of the second trailer.
