Abstract
A method includes automatically operating an electrified vehicle in a noise reduction mode, via a control system of the electrified vehicle, if, based at least on noise restriction information and driver history information received by the control system, a current time and a current location of the electrified vehicle are appropriate for invoking the noise reduction mode.
Claims19
A method, comprising:
- automatically operating an electrified vehicle in a noise reduction mode, via a control system of the electrified vehicle, when, based at least on noise restriction information and driver history information received by the control system, a current time and a current location of the electrified vehicle are appropriate for invoking the noise reduction mode,
- wherein the driver history information is obtained from a driver history database.
A method, comprising:
- automatically operating an electrified vehicle in a noise reduction mode, via a control system of the electrified vehicle, when, based at least on noise restriction information and driver history information received by the control system, a current time and a current location of the electrified vehicle are appropriate for invoking the noise reduction mode,
- wherein automatically operating the electrified vehicle in the noise reduction mode is further based on environmental information,
- wherein the environmental information includes ambient temperatures or a presence of nearby pedestrians or objects.
An electrified vehicle, comprising:
- a drive wheel;
- an engine;
- an electric machine, wherein both the engine and the electric machine are adapted to selectively supply torque for powering the drive wheel;
- and
- a smart noise reduction control system configured to control the electrified vehicle in a noise reduction mode based at least on a current time, a current location, noise restriction information, and driver history information,
- wherein the driver history information is obtained from a driver history database.
