Provided is a pressure regulating method in a vehicle, comprising the following steps: S1, detecting a pressure value P in a vehicle compartment; and S2, regulating and correcting the angle of a waste exhaust valve by a control apparatus according to a starting command until target requirements are met. A pressure regulating apparatus in a vehicle for realizing the pressure regulating method is further comprised. The pressure in a vehicle compartment is regulated by regulating the angle of an exhaust valve, so that the pressure in the vehicle compartment is always controlled within a reasonable range, and the problem of pressure change in a vehicle during the operation of the vehicle is solved; meanwhile, comfort of sitting in the vehicle is achieved, and the cost of testing is lowered.
