Lift arm assembly for a front end loading refuse vehicle

A refuse vehicle comprising:

• a chassis;
• a body coupled to the chassis;
• a cab coupled to the chassis and positioned in front of the body;
• a lift assembly coupled to at least one of the chassis or the body, the lift assembly including:
• a first arm;
• a second arm;
• an implement coupled to the first arm and the second arm;
• and
• an actuator positioned to pivot the first arm and the second arm to facilitate repositioning the lift assembly between a plurality of positions including a stowed position where the implement is positioned above the body, a working position where the implement is positioned in front of the cab, and a transit position between the stowed position and the working position, wherein repositioning the lift assembly between the transit position and the working position causes the implement to move past a windshield of the cab;
• and
• a control system configured to:
• acquire environment data from a GPS system regarding an environment ahead of the vehicle;
• acquire position data regarding a current position of the lift assembly;
• identify a low clearance environment and that the current position is the transit position based on the environment data and the position data;
• and
• automatically reposition the lift assembly closer to the working position from the transit position prior to the refuse vehicle encountering the low clearance environment in response to the position data indicating that the lift assembly needs to be repositioned to accommodate the low clearance environment.

• a user interface including a display screen;
• and
• a control system configured to:
• control the display screen to provide a graphical user interface displaying (i) a first visual indication including a graphical representation of the refuse vehicle indicating a current position of the lift assembly relative to the cab and the body and (ii) a second visual indication indicating a current maximum height of the lift assembly at the current position;
• in response to a speed threshold being reached while the lift assembly is not in the transit position, (i) limit a speed of the refuse vehicle and (ii) provide a notification via the user interface requesting operator approval to reposition the lift assembly to the transit position to permit further acceleration;
• acquire environment data from a GPS system regarding an upcoming low clearance environment;
• and
• automatically reposition the lift assembly closer to the working position from the transit position based on the environment data without requiring operator intervention to accommodate a low clearance environment prior to the refuse vehicle encountering the low clearance environment.
