AI Technical Summary

Technical Problem

In the event of an electrical failure, the performance of the trailer brake system is difficult to maintain, which may lead to loss of braking function and vehicle safety risks.

Method used

By introducing a second ECU into the trailer brake system, receiving sensor data and communicating with the trailer brake module and the trailer truck, braking pressure is adjusted to achieve redundant braking control, enabling the main system to function as a relay valve.

Benefits of technology

In the event of an electrical fault, electronically controlled braking, load-related braking and stability functions are provided to ensure that the vehicle still has fully staged braking and stability functions in the event of a failure.

Abstract

A trailer braking system. A method of controlling brake pressure in a trailer brake system that includes a trailer brake module for controlling pressure to generate braking force on one or more wheels of a trailer. The brake system includes a second ECU configured to receive sensor input from a sensor on the trailer, and configured to communicate with the trailer brake module and with the towing vehicle. If the second ECU determines that the pressure should increase or decrease, the second ECU can control the input pressure of the trailer brake module and / or one or more brake pressures on the output side of the trailer brake module.
