Abstract
A method and system for operating a powertrain that includes a transmission with two power take-off outputs and transmission output shaft is described. In one example, the powertrain is operated in a speed control mode whereby vehicle speed is controlled so that powertrain control may be simplified when a vehicle is moving and a power take-off is supplying power to an external device.
Claims20
A powertrain, comprising:
- a transmission including a power take-off and an output shaft that delivers torque to vehicle wheels, where the power take-off is coupled to the output shaft via a planetary gear set;
- and
- a controller including executable instructions that cause the controller to operate the powertrain in a first speed control mode where an output shaft rotational speed is controlled via the controller in response to a vehicle that includes the powertrain traveling with rotating wheels while delivering power to the power take-off.
A method for operating a powertrain, comprising:
- operating the powertrain in a speed control mode where a speed of a vehicle speed is controlled to a requested vehicle speed via a controller and in response to a power take-off supplying power to a device external to a transmission and a vehicle that includes the transmission traveling with rotating wheels.
A powertrain, comprising:
- a transmission including a first power take-off port including a power take-off shaft that rotates at a multiple of a rotational rate of a first shaft, the first shaft coupled to a ring gear of first planetary gear set, a second shaft configured to deliver power to vehicle wheels, the second shaft coupled to carrier planetary gears of the first planetary gear set;
- and a second power take-off port, the second power take-off port coupled to a sun gear of the first planetary gear set, the first power take-off port and the second power take-off port not configured to be coupled to the second shaft, except via the first planetary gear set;
- and
- a controller including executable instructions that cause the controller to operate the powertrain in a speed control mode in response to a vehicle that includes the powertrain traveling with rotating wheels while delivering power to the second power take-off port.
