Abstract
A vehicle including a chassis, a lift axle coupled to the chassis and including a tractive element, a lift actuator coupled to the lift axle, a location sensor configured to provide location data indicating a location of the vehicle, and a controller operatively coupled to the lift actuator and the location sensor and configured to control the lift actuator to reposition the lift axle based on the location data.
Claims11
A vehicle, comprising:
- a chassis;
- a mixing drum rotatably coupled to the chassis;
- a fill level sensor configured to provide a signal indicative of a fill level of a material within the mixing drum;
- an axle assembly coupled to the chassis and including a first tractive element;
- a suspension actuator coupled to the axle assembly and configured to apply a biasing force that forces the first tractive element into engagement with a ground surface;
- a lift axle coupled to the chassis and including a second tractive element;
- a lift actuator coupled to the lift axle;
- a location sensor configured to provide location data indicating a location of the vehicle;
- and
- a controller operatively coupled to the fill level sensor, the suspension actuator, the lift actuator, and the location sensor and configured to:
- calculate a target weight to be supported by the first tractive element;
- control the suspension actuator to vary the biasing force based on the fill level of the material within the mixing drum and the target weight;
- and
- control the lift actuator to reposition the lift axle based on the location data.
