Abstract
Systems and methods for operating a power take off of a vehicle are described. In one example, operation of the power take off may be maintained even when slip of a power take off clutch is detected. In particular, the power take off may be operated at a lower output until the power take off may handle larger loads.
Claims20
A method for operating a power take off of a vehicle gearbox, comprising:
- maintaining or increasing a closing force applied to a clutch of the power take off and reducing torque output of an electric machine in response to slip of the clutch exceeding a threshold.
A system, comprising:
- a power source;
- a driveline including a gearbox and a power take off coupled to the gearbox, the power take off including a clutch;
- and
- a controller including executable instructions stored in non-transitory memory that cause the controller to maintain or increase a closing force that is applied to the clutch and adjust a torque of the power source in response to a vibration level of the power take off.
1 more element
A method for operating a power take off of a vehicle gearbox, comprising:
- increasing a speed of an electric machine in response to a temperature of a power take off after reducing torque output of the electric machine in response to slip of a clutch of the power take off exceeding a threshold.
