The invention belongs to the technical field automobile trailer circuits, and particularly relates to a trailer steering lamp control system and a control method. The trailer steering lamp control system comprises a vehicle body controller, an ignition lock ON gear switch, a pressure sensor, a trailer steering lamp, a main vehicle steering lamp and a steering lamp switch, wherein the ignition lock ON gear switch is electrically connected with the vehicle body controller; the pressure sensor, the trailer steering lamp, the main vehicle steering lamp and the steering lamp switch are electrically connected with the vehicle controller respectively; the pressure sensor is arranged on a traction disk of a main vehicle frame, and is used for detecting pressure carried by a frame; the vehicle body controller determines whether a vehicle steers or not by detecting a steering lamp switch signal and an ignition lock ON gear switch signal, acquires a pressure signal of the pressure sensor after determining that the vehicle steers, and controls the main vehicle steering lamp and / or the trailer steering lamp to be turned on according to the pressure signal. By adopting the trailer steering lamp control system and the control method, the indication accuracy of the trailer steering lamp is increased.
Description
technical field [0001] The invention belongs to the technical field of automobile trailer circuits, and in particular relates to a trailer turn signal control system and a control method. Background technique [0002] In the current technology, the tractor will hang one or more trailers, and it is necessary to frequently unload or add trailers. The GB4785 document approved by the National Standardization Management Committee clearly stipulates that when the turn signal fails, the turn signal will flash twice and the sound frequency should be synchronized. Therefore, when the trailer does not exist, the flasher of the main vehicle cannot accurately determine the status of the trailer's turn signal, and there is a risk of false alarm failure. [0003] Specifically, in the prior art, the flasher of the main vehicle controls the turn signal of the main vehicle and the turn signal of the trailer. When the switch of the turn signal of the main vehicle is detected to be effective,...
