Trailer with a trailer brake control device therein
First Claim
1. A trailer brake control device arranged in a trailer for controlling a brake which provides force on at least one wheel of the trailer, the trailer brake control device comprising:
- a sway detecting sensor arranged in the trailer for detecting the sway of the trailer;
a signal sensor for detecting a brake signal generated by a brake switch of a vehicle which tows the trailer and for detecting a control signal generated by a brake controller in the vehicle; and
a processor, electrically connected to the sway detecting sensor, the signal sensor and the brake, for controlling the brake based on an output of the sway detecting sensor and an output of the signal sensor;
wherein the processor compares the brake signal and the control signal and determines whether the brake controller functions or malfunctions based on whether the brake signal and the control signal are compatible or incompatible.
