AI Technical Summary

Technical Problem

In existing commercial vehicle braking systems, when semi-trailer tractors use electromechanical braking, the trailer's air pressure braking system suffers from numerous parts, complex pipelines, high noise, and slow updates, making it difficult to coordinate braking performance control.

Method used

The vehicle-trailer braking control system, which combines electromechanical braking with pneumatic braking, achieves precise control of the tractor's electric braking and the semi-trailer's pneumatic braking through the coordinated operation of components such as a brake signal generator, EPB switch, EMB controller, wheel-side brakes, and trailer controller.

Benefits of technology

The system configuration has been simplified, control precision and response speed have been improved, and the overall vehicle braking safety and comfort have been enhanced. At the same time, the trailer can use mature air pressure braking technology without modification, enabling rapid market promotion.
