Abstract

Systems and methods for improving operation of a vehicle are presented. In one example, automatic engine stopping is inhibited in response to a driver communicating a desire to not automatically stop an engine. The driver communicates intentions to allow or inhibit automatic engine stopping via a brake pedal.

Description

FIELD

[0001] The present description relates to a system and methods for improving vehicle drivability and driver controls. The systems and methods may be particularly useful for engines that may be frequently stopped and restarted to conserve fuel.BACKGROUND AND SUMMARY

[0002] An engine of a vehicle may be automatically stopped without a driver providing input to a device that has a sole purpose or function of stopping engine rotation so that fuel may be conserved (e.g., engine stop / start devices). Fuel may be conserved when the engine is automatically stopped since the engine does not consume fuel when it is not operating. However, if the engine is restarted immediately after it is stopped, the fuel reduction may be less than desired. Further, the driver may be annoyed that the engine has stopped and is being restarted so quickly after being stopped. Thus, automatically stopping an engine may conserve fuel, but it may also be less than desirable during some driving conditions. Present...
