Trailer Electronic Braking System
First Claim
1. A trailer braking system for a vehicle having at least first and second trailers, the system comprising:
- a braking system of the first trailer comprising a brake capable of generating a brake force on an axle on the first trailer, the brake force being controllable by a first braking ECU in dependence on an output of a sensor adapted to detect at least one of lateral acceleration and wheel speed of the first trailer;
a second braking system of the second trailer comprising a brake capable of generating a brake force on an axle of the second trailer, the brake force being controllable by an ABS valve;
a communication interface being operatively configured such that the ABS valve is controllable by the first braking ECU; and
wherein, in an event that the sensor detects lateral acceleration and/or a wheel speed indicative of loss of stability, the sensor generates a signal for actuating stability control in the first trailer and the first braking ECU generates a signal to apply the brakes of the second trailer.

Abstract
A trailer electronic braking system for a road train includes a tractor and a plurality of trailers. The braking system includes a braking ECU on at least one trailer and an ABS system on a further trailer. A communication interface is provided so that the braking ECU on a first trailer and the ABS control unit on a second trailer are able to communicate with one another. In use, the braking ECU on the first trailer receives an input from a respective sensor on the first trailer adapted to detect lateral acceleration anchor wheel speed. In the event that the sensor detects lateral acceleration anchor a wheel speed indicative of a loss of stability, the sensor generates a signal for actuating stability control, which signal is passed via the communication interface to the ABS control unit on the other trailer, so that the other trailer can actuate the brakes on that trailer.

9. A method of operating a braking system of a motor vehicle having at least a first and a second trailer, the method comprising the acts of:
-
detecting in the first trailer, which is equipped with a braking ECU for controlling a brake force, a signal indicative of loss of stability; generating a signal for actuating stability control in the first trailer; and generating, by the braking ECU of the first trailer, a signal to apply brakes on the second trailer, which is equipped with an ABS valve for controlling a brake force of the second trailer. - View Dependent Claims (10, 11)
