Systems and methods for capturing fluid change history in a vehicle are provided. A method includes: detecting, by a computer device, a fill cap is removed from an inlet port of a fluid reservoir or a drain plug is removed from an outlet port of the fluid reservoir; activating, by the computer device and based on the detecting, one of a fill sensor and a drain sensor; obtaining, by the computer device, fluid characteristics data from one of the fill sensor and the drain sensor; determining, by the computer device, at least one fluid parameter based on the fluid characteristics data; and transmitting, by the computer device, the determined at least one fluid parameter to a remote system via a communication network that is external to the vehicle.

A method of determining wear of a seal element includes rotating a seal plate relative to the seal element and such that the seal plate and the seal element form a rotational sealing interface. The seal element includes an insert embedded in the seal element. A portion of the seal element is worn with a sealing face of the seal plate. The insert is contacted with the sealing face of the seal plate. A portion of the insert is worn to create a wear particle of the insert. The presence of the wear particle in a lubrication oil is sensed with an oil monitoring system.

A controller for a vehicle is configured to execute a lubricating oil degradation degree acquisition process that calculates a degradation degree of a lubricating oil that lubricates an internal combustion engine, a battery degradation degree acquisition process that calculates a degradation degree of a battery, and an oil change time calculation process that calculates an oil change time for the lubricating oil from the degradation degree of the lubricating oil and the degradation degree of the battery. The oil change time calculation process includes calculating the oil change time so as to become earlier as the degradation degree of the battery increases.

A method for providing the engine oil usage information may include determining, by a controller, a current engine driving state out of a plurality of predetermined driving states of an engine of the hybrid electric vehicle from driving information, determining, by the controller, a real-time cumulative distance value corresponding to the determined current engine driving state, updating, by the controller, an oil usage distance using the real-time cumulative distance value, determining, by the controller, an engine oil change time by comparing the updated oil usage distance with a predetermined engine oil change distance, and informing, by the controller, information related to the determined engine oil change time through a notification unit.

A fluid degradation monitoring system may detect a replacement of a fluid of a machine. The fluid degradation monitoring system may determine, after detecting the replacement of the fluid, a first degradation estimate of the fluid using a first technique based on characteristics relating to an operation of the machine. The fluid degradation monitoring system may detect a transition in a value of a dielectric constant of the fluid from a first phase to a second phase. The fluid degradation monitoring system may determine, after detecting the transition in the value of the dielectric constant, a second degradation estimate of the fluid using a second technique based on characteristics relating to the fluid.

Methods and systems for failure prediction using analysis of oil or other lubricant. Raw data about feature(s) of each of a plurality of particles filtered from a fluid sample are used to categorize each particle into one of a plurality of categories, each category being defined by one or more of: chemical composition, size and morphology. Particle physical characteristics in each category are quantified to obtain a set of categorized data. The categorized data are compared with historical data. Results of the comparing are evaluated to generate a prediction of any failure or mechanism of failure.

A vehicle system includes: at least one of: (a) a particulate matter sensor configured to measure an amount of particulate within a passenger cabin of a vehicle; and (b) a volatile organic compounds (VOC) sensor configured to measure an amount of VOCs within the passenger cabin of the vehicle; and a control module configured to, based on at least one of the amount of particulate and the amount of VOCs within the passenger cabin of the vehicle, diagnose at least one of: a characteristic of the vehicle; presence of a chemical in the passenger cabin of the vehicle; occurrence of an event within the passenger cabin of the vehicle; and a remaining life of engine oil of the vehicle.

A method for operating an internal combustion engine with a motor, having a moving machine part and at least one machine element which retains the moving machine part and is subject to wear, such as, for example, a supporting, sealing, guiding or the like retaining machine element that is subject to wear during operation relative to the moving machine part, which machine element, because of the wear, is service-life-limiting for the operation of the internal combustion engine, wherein—for the operation of the internal combustion engine, a service-life-limiting time interval until the next maintenance of the internal combustion engine is specified, and—the internal combustion engine has a number of service-life-limiting machine elements, wherein for the at least one service-life-limiting machine element a remaining service life is forecast and the service-life-limiting time interval is determined therefrom.
