自适应节能控制方法、装置、设备、系统及车辆

The application provides a self-adaptive energy-saving control method, device, equipment and system and a vehicle, and relates to the technical field of vehicle control. The method comprises the steps of detecting the trailer connection state of a tractor if a new energy vehicle is in a parking mode, controlling an air circuit electromagnetic valve arranged on a main air circuit pipeline between the tractor and the trailer to be opened and starting an inflating pump to inflate the pressure of a trailer air storage cylinder on the tractor to a preset initial pressure maintaining threshold value if the tractor is connected with the trailer, controlling the inflating pump to stop working and monitoring the pressure of the trailer air storage cylinder after the pressure reaches the preset initial pressure maintaining threshold value to obtain a monitored pressure value of the trailer air storage cylinder, determining the leakage level of a trailer braking loop according to the monitored pressure value, and correspondingly controlling the air circuit electromagnetic valve and the inflating pump according to the leakage level. The application can avoid frequent awakening of the air pump in the parking process, reduce energy consumption and noise, and improve the driving range, rest comfort and service life of the air pump of the whole vehicle.
