Zusammenfassung:An electronic control device (1) for use in a motor vehicle has an electronic housing (2) for receiving an electronic component (3) comprising a circuit board (5), and a capacitive sensor (16). Wherein the capacitive sensor (16) comprises at least one capacitive sensor electrode (20) arranged inside the electronics housing (2) and a control unit (18); the control unit is designed to detect and evaluate a capacitance measurement quantity (C sensor) captured at the sensor electrode (20). The control unit (18) is configured to output a trigger signal when the detected capacitance measurement quantity (C sensor) or a deviation of the capacitance measurement quantity from a normal value satisfies a trigger criterion for characterizing the presence of water (22) or other electrically conductiveor insulating liquid in the electronics housing (2). 一种电子控制设备(1),其用于机动车中并且具有用于容纳包括电路板(5)的电子器件(3)的电子器件壳体(2)和电容式传感器(16)。电容式传感器(16)包括至少一个布置在电子器件壳体(2)内部的电容式传感器电极(20)以及控制单元(18),控制单元设立用于检测和评估在传感器电极(20)处截取的电容测量量(C)。控制单元(18)设立用于,在检测到
