Trailer electronic braking system
First Claim
1. A trailer electronic braking system for a motor vehicle having at least first and second trailers, the trailer electronic braking system comprising:
- a first braking ECU on the first trailer;
a second braking ECU on the second trailer, the first and second braking ECUs being operatively configured to control a brake force into a brake;
a communication interface coupling the first braking ECU on the first trailer and the second braking ECU on the second trailer so that the first and second braking ECUs are able to communicate with one another;
a first sensor associated with the first trailer being adapted to detect at least one of lateral acceleration and wheel speed;
a second sensor associated with the second trailer being adapted to detect at least one of lateral acceleration and wheel speed;
wherein the respective braking ECUs on the first trailer and the second trailer receive an input from a corresponding to one of the sensors on the first trailer and the second trailer; and
wherein, in an event that one of the first and second sensors detects lateral acceleration and/or wheel speed indicative of a loss of stability, said sensor generates a signal for actuating stability control, which signal is passed via the communication interface to the braking ECU on the other trailer in order for the other trailer to actuate stability control.

Abstract
A trailer electronic braking system is provided for a road train having a tractor and a plurality of trailers. The braking system includes a braking ECU on each trailer and a communication interface being provided so that the braking ECU on a first trailer and the braking ECU on a second trailer are able to communicate with one another. In use, the respective braking ECU on the first and second trailer receive an input from a respective sensor on the first and second trailer adapted to detect lateral acceleration and/or wheel speed. In the event that one of the sensors detects lateral acceleration and/or 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 braking ECU on the other trailer, so that the other trailer can actuate stability control.
