Abstract
Systems and methods for improving operation of a hybrid vehicle are presented. In one example, driveline operating modes may be manually selected to improve hybrid driveline operation during off road conditions. The approaches may improve vehicle drivability and reduce driveline degradation.
Claims20
A method of adjusting operation of a hybrid vehicle driveline, comprising:
- providing a manual driver input for a driveline operating mode parameter;
- and
- adjusting engaging of a driveline disconnect clutch positioned between an engine and a motor in response to the driveline operating mode parameter and further in response to an accelerator pedal input, where a prompting of a driver occurs in response to the driver selecting a four wheel drive mode of operation.
A method of adjusting operation of a hybrid vehicle driveline, comprising:
- providing a manual driver input for a driveline operating mode parameter comprising providing motive power via solely by an engine, solely by a motor, or by a combination of the engine and the motor in response to a request for a four wheel drive mode of operation;
- and
- adjusting activation of a driveline integrated electric machine in response to the driveline operating mode parameter.
A method of adjusting operation of a hybrid vehicle driveline, comprising:
- providing a manual hill descent control input for a driver;
- and
- providing a manual driver input for adjusting activation of a driveline disconnect clutch in response to a state of the hill descent control input.
