Zusammenfassung:Embodiments provide an oil pan that includes an oil pan having a reservoir configured to hold oil and defined by one or more oil pan walls and an oil pan bottom. The oil pan includes one or more capacitance sensors coupled to a portion of the oil pan walls and configured to sense a capacitance. The oil pan includes a capacitance measuring unit electrically connected to the one or more sensors via one or more conductors and configured to receive each of the sensed capacitances via the one or more conductors and determine capacitance values for each of the sensed capacitances. The oil pan also includes a processor configured to receive the capacitance values and determine the oil level in the oil pan based on the capacitance values. 实施方式提供种油盘,包括油盘,具有被配置成保存油并由个或多个油盘壁和油盘底限定的油箱。油盘包括耦合到油盘壁的部分并被配置成感测电容的个或多个电容传感器。油盘包括经由个或多个导体电连接到个或多个传感器的电容测量单元,且电容测量单元被配置成经由个或多个导体接收所感测的电容的每个电容,并确定所感测的电容的每个电容的电容值。油盘还包括处理器,其被配置成接收电容值并基于电容值来确定油盘中的油位。
