| 摘要 | In a method for leak testing in an automated electrohydraulic clutch system in a motor vehicle, in which an electromechanical actuator controls the clutch travel of a clutch via a hydraulic piping system, in order that a defective system is detected reliably and rapidly, the leak in the clutch system is detected using a pressure measurement in the electromechanical actuator and compared to a characteristic clutch curve. | ||

| 主权项 | 1. A method for leak testing in an automated electrohydraulic clutch system in a motor vehicle, comprising: controlling a clutch travel of a clutch by an electromechanical actuator via a hydraulic piping system; detecting a leak in the clutch system using a pressure measurement in the electromechanical actuators; ascertaining a maximum pressure of the electrohydraulic clutch system; determining a starting pressure point for pressure measurement based on the maximum pressure; measuring a pressure change over a predetermined time; comparing the pressure change to a threshold value; and detecting a leak in response to the threshold value being exceeded. | ||
