Abstract
Systems and methods for improving operation of a hybrid vehicle are presented. In one example, driveline operation may be adjusted in response to operating the hybrid vehicle in a four wheel drivel low gear range. The approaches may improve vehicle drivability and reduce driveline degradation.
Claims18
A method of adjusting operation of a hybrid vehicle, comprising:
- automatically restarting an engine in response to a first condition while the hybrid vehicle is operating in a four wheel drive low gear range;
- and
- automatically restarting the engine in response to a second condition other than the first condition while the hybrid vehicle is not operating in the four wheel drive low gear range.
A method of adjusting operation of a hybrid vehicle, comprising:
- automatically restarting an engine in response to release of a vehicle brake while the hybrid vehicle is operating in a four wheel drive low gear range;
- and
- commanding a torque to a torque converter impeller while the hybrid vehicle is operated in the four wheel drive low gear range that is different than a torque supplied to the torque converter impeller during similar operating conditions while the hybrid vehicle is operated in a two wheel drive mode.
15-20. (canceled)
A method of adjusting operation of a hybrid vehicle, comprising:
- automatically restarting a stopped engine in response to a driver selecting a four wheel drive range.
