Embodiment Construction

[0016] Embodiments include methods of measuring the oil level of oil-containing containers (e.g., oil pans) in different types of motor vehicles, such as automobiles (cars), trucks, buses, motorcycles, watercraft (e.g., boats and boats), and aircraft and system. However, for simplicity of illustration, the embodiments described herein include methods and systems for measuring the oil level of a fuel container in an automobile 100 .

[0017] figure 1 is a system block diagram of an exemplary oil level measurement system 100 . Such as figure 1 As shown, the example oil level measurement system 100 may include an oil pan 102 and one or more sensors 104 . Oil pans can include power supplies such as figure 1 The battery shown in 106. The oil pan may also include a processor 108 , a capacitance measurement unit 109 , a transmitter 110 , a receiver 112 , a computer 114 and a user interface 116 . In some implementations, transmitter 110 and receiver 112 may be integrated into a ...

Abstract

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.

Description

[0001] Cross References to Related Applications [0002] This application claims the benefit of U.S. Provisional Patent Application No. 62 / 114,857, filed February 11, 2015, and U.S. Nonprovisional Patent Application No. 14 / 946,441, filed November 19, 2015, which are hereby incorporated by reference as if fully set forth in this application. technical field [0003] The present disclosure relates to motor vehicle oil pans, and in particular to motor vehicle oil pans with integrated capacitive sensors for measuring oil level. Background technique [0004] Oil plays an important role in motor vehicles by providing lubrication that can reduce wear and damage to components during operation of the motor vehicle. The oil reduces the heat caused by friction when components rub against each other during operation. When the oil is not being utilized, it is typically stored in an oil pan within the body of the vehicle. As the oil is consumed during operation, the oil's ability to pe...
