Common heavy trucks are pneumatically controlled to brake, and most of heavy trucks have air cylinders driven by engines to supply air to the air cylinders, so that the braking effect is achieved. Generally, an air compressor is directly connected with an engine and works synchronously with the engine, and when the engine runs, the air compressor also runs and can only be opened or closed according to the state of the engine, so that the oil consumption of a vehicle is high, and the fuel economy of the engine is not facilitated.

By adding judgment of the running state of the vehicle, when the vehicle is accelerated (the opening degree of an accelerator is larger than 0), the gas consumption of the vehicle is small (no braking requirement), the gas pumping can be stopped when the pressure reaches 11.5Bar, and the air compressor stops running to save fuel; when the vehicle is not accelerated (the opening degree of an accelerator is equal to 0), the air consumption of the vehicle is large (the vehicle has a braking requirement), and when the pressure is lower than 11.5Bar, the air is immediately pumped to 12.5Bar to ensure sufficient air consumption and brake performance.
In one embodiment, an electromagnetic clutch is additionally arranged on the air compressor, the operation of the air compressor is controlled by controlling the actuation and the disconnection of the electromagnetic clutch through an electric control dryer, and it should be noted that the electromagnetic clutch is engaged by default, the air compressor is disconnected when the electromagnetic clutch is actuated in an electrified mode, and the air compressor is engaged when the electromagnetic clutch is disconnected in a power-off mode, so that the air compressor can still operate when the electromagnetism fails.
