Abstract
A system is described, as well as methods of using the system. The method includes: determining an error within the vehicle driveline system; following the error, determining that a state of a power take-off unit (PTU) within the system is determinable; and then transferring a normal torque from the PTU to a secondary drive unit (SDU) during the error.
Claims21
A method for controlling a vehicle driveline system, comprising:
- determining an error within the system;
- following the error, determining that a state of a power take-off unit (PTU) within the system is determinable, wherein determining that the state of the PTU is determinable comprises determining whether to trust any received electrical data associated with identifying the state of the PTU;
- and then
- transferring a torque from the PTU to a secondary drive unit (SDU) during the error.

A system for controlling a vehicle driveline, comprising:
- a computer, comprising a processor and memory storing instructions executable by the processor, the instructions comprising, to:
- determine an error within the system;
- and
- following the error, determine that a state of a power take-off unit (PTU) is determinable;
- and then,
- transfer a torque from the PTU to a secondary drive unit (SDU) during the error, wherein determining that the state of the PTU is determinable comprises determining whether to trust any received electrical data associated with identifying the state of the PTU.
3 more elements
A vehicle driveline system, comprising:
- a secondary drive unit (SDU);
- and
- a computer, comprising a processor and memory storing instructions executable by the processor, the instructions comprising, to:
- determine an origin of an error in the vehicle driveline system;
- when the origin of the error occurs in a power take-off unit (PTU), then determine that a state of the PTU is determinable, wherein determining that the state of the PTU is determinable comprises determining whether to trust any received electrical data associated with identifying the state of the PTU;
- and
- when the state of the PTU is determinable, then transfer a torque from the PTU to the SDU during the error.
