Abstract
Methods and systems for operating a hybrid vehicle that includes an internal combustion engine, an electric machine, and a transmission are described. In one example, various vehicle operating modes may be entered from a baseline vehicle operating mode and the vehicle operating modes may revert back to the baseline vehicle operating mode in a plurality of stages so that returning to the baseline operating mode may be less noticeable to vehicle occupants.
Claims19
A vehicle operating method, comprising:
- substantially simultaneously activating a plurality of vehicle control parameter staging groups via a controller and operating a vehicle responsive to the plurality of vehicle control parameter staging groups in response to a vehicle mode being selected;
- and
- via the controller, deactivating the plurality of vehicle control parameter staging groups asynchronously and operating the vehicle responsive to baseline control parameters responsive to one or more conditions being met while operating in the vehicle mode,
- where the one or more conditions being met include one or more conditions being met to deactivate the plurality of staging groups, and where a second staging group is deactivated a predetermined time after a first staging group is deactivated, and where vehicle control parameters within the first staging group are ramped at a predetermined rate in response to the first staging group being deactivated,
- wherein the plurality of staging groups are activated asynchronously according to noise levels related to the plurality of staging groups.

A vehicle operating method, comprising:
- via a controller, grouping more than one vehicle control parameter limits into a plurality of staging groups included in a vehicle mode, the vehicle mode included in a plurality of vehicle modes including a performance mode and a track mode;
- via the controller, substantially simultaneously activating the plurality of staging groups and operating a vehicle responsive to a vehicle mode being selected;
- and
- via the controller, deactivating the plurality of staging groups asynchronously according to a predetermined order of staging group deactivation responsive to one or more conditions being met to deactivate the plurality of staging groups,
- where the predetermined order of staging group deactivation first deactivates a higher noise staging group of the plurality of staging groups and then deactivates a lower noise staging group in the plurality of staging groups.
2 more elements
A system, comprising:
- an engine;
- an electric energy storage device;
- a motor/generator;
- and
- a controller including executable instructions stored in non-transitory memory to operate the engine, electric energy storage device, and motor/generator responsive to a plurality of staging groups that are activated at a substantially same time and deactivated asynchronously, and deactivate the plurality of staging groups asynchronously according to noise levels related to the plurality of staging groups.
