Abstract
Methods and systems are provided for a vehicle having a plurality of axles and a lift mechanism configured to dynamically transfer weight from one axle to another. In one example, the method comprises, responding to an operating condition by adjusting the lift mechanism to provide a determined amount of lift, and in response to vehicle braking, a vehicle stall risk, poor infrastructure conditions, and/or a high vehicle penalty, reducing the determined amount of lift.
Claims23
A method for a vehicle having a plurality of axles and a lift mechanism configured to dynamically transfer weight from one axle to another, the method comprising:
- responding to an operating condition by adjusting the lift mechanism to provide a determined amount of lift;
- and
- in response to vehicle braking, reducing the determined amount of lift.
A method for a vehicle having a plurality of axles and a lift mechanism configured to dynamically transfer weight from one axle to another, the method comprising:
- responding to an operating condition by adjusting the lift mechanism to provide a determined amount of lift;
- and
- in response to identification of a vehicle stall risk, increasing the determined amount of lift.
A method for a vehicle having a plurality of axles and a lift mechanism configured to dynamically transfer weight from one axle to another, the method comprising:
- responding to an operating condition by adjusting the lift mechanism to provide a determined amount of lift;
- and
- in response to an infrastructure condition, reducing the determined amount of lift.
A vehicle system, comprising:
- a truck with a plurality of axles and a lift mechanism configured to dynamically transfer weight from one axle to another;
- and
- a control system with a computer readable storage medium and instructions for,
- responding to an operating condition by adjusting the lift mechanism to provide a determined amount of lift;
- determining a vehicle penalty based at least on lift mechanism component stress, locomotive component stress, wheel slip, vehicle stall risk, fuel level, and lift mechanism actuator forces;
- and
- limiting the determined amount of lift based on the determined vehicle penalty.
