Embodiment Construction

[0028] The present invention generally relates to monitoring contaminants in a lubrication system within a vehicle. In some examples, the vehicle enters maintenance mode in response to detecting contamination within the lubrication system. The maintenance mode may include starting the internal combustion engine.

[0029] Such as figure 1 As shown, a plug-in hybrid electric vehicle (PHEV) drivetrain 10 includes a traction battery 14 having a battery unit 18 . The powertrain 10 also includes an internal combustion engine 20 , a motor 22 and a generator 24 . Motor 22 and generator 24 are types of electric machines. Motor 22 and generator 24 may be separate or in the form of a combined motor-generator.

[0030] In this embodiment, the powertrain 10 is a power split powertrain employing a first drive system and a second drive system. The first and second drive systems generate torque to drive one or more sets of vehicle drive wheels 28 . The first drive system includes a comb...

Abstract

An exemplary monitoring assembly includes a sensor that provides a first output when a lubricant reservoir holds a first amount of contamination, and a different first output when the lubricant reservoir holds a second, different amount of contamination. Two outputs. A lubrication system monitoring controller is operatively connected to the sensor and configured to initiate a maintenance mode in response to the second output.

Description

technical field [0001] The present invention relates generally to monitoring lubrication systems within vehicles, and more particularly to monitoring lubrication systems for contamination. Background technique [0002] Electric vehicles differ from conventional motor vehicles in that electric vehicles are selectively propelled using one or more electric machines powered by traction batteries. The electric machine can drive the electric vehicle instead of or in addition to the internal combustion engine. Example electric vehicles include hybrid electric vehicles (HEV), plug-in hybrid electric vehicles (PHEV), fuel cell vehicles (FCV), and battery electric vehicles (BEV). [0003] Both electric vehicles and conventional motor vehicles may utilize lubrication systems that circulate lubricant, such as oil, through the internal combustion engine and other areas. Operating an internal combustion engine can inhibit the undesired accumulation of water and other contaminants within...
