The invention provides an adjusting system, a pump type retarder and a vehicle, and relates to the technical field of automobile retarders, the adjusting system is used for the pump type retarder and comprises a main body and a rotor, a working cavity is formed in the main body, the rotor is arranged in the working cavity and divides the working cavity into a high-pressure area and a low-pressure area, and the high-pressure area is communicated with the low-pressure area. The adjusting system comprises a variable pump, an oil storage expansion cavity, an unloading valve, a flow control valve, a first control valve, a second control valve, a third control valve, a first oil way and a second oil way. The unloading valve is arranged between the high-pressure area and the low-pressure area, and the flow control valve is arranged between the oil outlet and the oil storage expansion cavity; the first oil way is arranged between the oil storage expansion cavity and the oil inlet, the first control valve, the variable pump, the second control valve and the third control valve are arranged on the first oil way, and the variable pump controls the opening degree of the unloading valve. The second oil way is arranged between the oil supplementing opening and the third control valve. By arranging the adjusting system, closed-loop control is carried out on the pressure in the working cavity, the torque of the rotor can be controlled in real time, the reaction speed is high, and the efficiency is high.
