Claims

[Scope of Claim for Utility Model Registration] A hydraulic actuator that operates a test brake to generate torque, a torque setting device that sets the torque of the test brake, a torque detector that detects the torque of the test brake, and the aforementioned A pressure detector detects the operating pressure applied to the test brake from the hydraulic actuator, and the target operating pressure value of the hydraulic actuator is determined according to the deviation between the torque setting value and the detected value of the test brake, and this operating pressure target value and and a hydraulic control circuit that controls the operating pressure of the test brake by the hydraulic actuator according to the deviation from the detected operating pressure value, and performs feedback control of the torque of the test brake so that it matches the set value of the torque. In the torque control circuit of the brake tester, there is a memory that stores the relationship value between the detected torque value and the operating pressure when a desired operating pressure is applied to the test brake, and a memory that stores the relationship value between the detected torque value and the operating pressure when the desired operating pressure is applied to the test brake, and the A torque control correction circuit for a brake tester, comprising a calculation circuit that calculates a related value and a torque setting value and corrects the operating pressure applied from a hydraulic actuator to a test brake.
