Abstract
An automatic pressure regulating valve for multiple levels of driving automation of a commercial vehicle includes an upper valve body, a lower valve body, a piston, a main valve core assembly, a switching valve, a quick-acting intake valve, and a quick-acting exhaust valve. The switching valve, the quick-acting intake valve and the quick-acting exhaust valve are all mounted at an upper end of the upper valve body. The piston is located in a chamber formed by the upper valve body and the lower valve body to divide the chamber into an upper control chamber and a lower chamber. The main valve core assembly is mounted in the lower valve body. The automatic pressure regulating valve is applicable to a commercial vehicle allowing for multiple levels of driving automation.
