A translatable assist handle system for a vehicle includes a guide track having a first end, a second end, and an intermediate portion having a guide surface that extends around at least a portion of a vehicle opening between the first end and the second end. A translatable assist handle including a guide element is disposed in the guide track. The translatable assist handle is selectively positionable along the guide track providing an adjustable hand hold aiding a passenger to ingress and egress from the vehicle.

Translatable assist handle for a vehicle

A vehicle has an electric drive mode, a body defining a vehicle interior, a first and second set of audio speakers positioned outside and inside of the interior, respectively, and a controller. The controller generates an acoustic signal, broadcasts the acoustic signal via the first set of speakers during an electric drive mode, and generates and broadcasts a cancelling signal via the second set of speakers. The broadcasts are coordinated to substantially cancel an attenuated portion of the acoustic signal resulting from propagation of the acoustic signal into the interior. A method cancels a synthesized sound within a vehicle interior by collecting vehicle operating values, generating an acoustic signal as the synthesized sound during an electric drive mode, and processing the acoustic signal to generate a modified acoustic signal approximating an attenuated portion of the acoustic signal propagating into the vehicle interior.
