Abstract

The invention relates to a dryer belonging to the field of automobiles, and specifically discloses an electrically controlled dryer assembly with an ECU (Electronic Control Unit) controller and a control method. The electrically controlled dryer assembly with the ECU controller has a protection function, namely when the pressure value of the dryer assembly is less than unloading pressure for a long time and reaches a set forced unloading pressure value for a period of time exceeding set time, the ECU controller controls an unloading electromagnetic valve assembly to be started to realize forced unloading and back flushing to protect the regeneration effect of a drying tank molecular sieve, and the service life of a dryer is greatly prolonged.

Description

Technical field [0001] The invention relates to a dryer used in the automotive field, in particular to an electronically controlled dryer assembly with an ECU controller and a control method. Background technique [0002] In the traditional dryer used in the automotive field, the air compressor has no start-stop function, which has poor energy-saving effect, and the use of the drying tank cannot be monitored. With the advancement of science and technology, the most commonly used dryers now include solenoid valves to realize electrical control. However, the controller and pressure sensor of this type of dryer need to be connected externally, which makes the circuit layout complicated and restricts the control logic and input and output signals. The most important thing is that the dryers currently in use usually only realize the functions of unloading and backflushing after the pressure reaches the unloading pressure. If the dryer is under a certain pressure (less than the unload...
