METHOD FOR DIAGNOSING A HYDRAULIC SYSTEM OF A MOTOR VEHICLE

The invention relates to a method for diagnosing a hydraulic system of a motor vehicle, wherein the hydraulic system forms a cooling loop. The cooling loop is provided with at least one to-be-cooled component, particularly a clutch, double clutches, a transmission or a motor. In a first step, the cooling loop is configured for injecting a first cooling flow to the to-be-cooled component and afterwards determining reaction of the to-be-cooled component. In the second step, the cooling loop is configured to injecting a second cooling flow to the to-be-cooled component, wherein the second coolingflow is higher than the first cooling flow; and afterwards determining the reaction of the to-be-cooled component, wherein the relation between the two reactions is determined for confirming the state of the cooling loop and furthermore confirming the state of the hydraulic system. 本发明涉及一种用于诊断机动车的液压系统的方法，其中液压系统形成冷却回路，其中在冷却回路中设置有至少一个待冷却的部件，尤其离合器、双离合器、变速器或电动机，其中在第一步骤中，将冷却回路配置成，以第一冷却流量流向待冷却的部件；随后确定待冷却的部件的反应；在第二步骤中，将冷却回路配置成，
