System and method for controlling an electric aspirator of an air intake system for a work vehicle

A system for controlling an air intake system for a work vehicle, the system comprising:

• a filter assembly including a pre-cleaner configured to separate particulates from air received by the filter assembly, the pre-cleaner defining a pre-cleaner outlet;
• an electric aspirator in fluid communication with the pre-cleaner outlet, the electric aspirator including a motor configured to rotate a fan so as to create a vacuum for scavenging the particulates separated from the air within the pre-cleaner;
• and
• a controller communicatively coupled to the electric aspirator, the controller being configured to determine an air intake flow into an engine of the work vehicle, the controller being further configured to vary a rotational speed of the motor based on changes in the air intake flow,
• wherein the rotational speed of the motor is varied such that a predetermined percentage of the air intake flow is scavenged from the pre-cleaner, and
• wherein the predetermined percentage ranges from about 5% to about 15% of the air intake flow into the engine.

• a particulate sensor communicatively coupled to the controller, the particulate sensor being configured to detect the presence of particulates contained within the air received by the filter assembly,
• wherein the rotational speed of the motor is varied such that a predetermined percentage of the air intake flow is scavenged from the pre-cleaner.

A method for controlling an air intake system for a work vehicle, the air intake system including a filter assembly having a pre-cleaner and an electric aspirator in fluid communication with the pre-cleaner, the method comprising:

• applying a vacuum via the electric aspirator to a pre-cleaner outlet of the pre-cleaner for scavenging particulates separated from air within the pre-cleaner;
• monitoring a load-based parameter of the work vehicle;
• varying a rotational speed of a motor of the electric aspirator based on changes in the load-based parameter;
• and
• monitoring the presence of particulates contained within the air received by the filter assembly.
