Abstract: Methods and systems for performing automatic speed-based audio control. One method includes receiving, with an electronic control unit included in a vehicle, a speed of the vehicle and receiving, with the electronic control unit, an audio signal. The method also includes accessing, with the electronic control unit, a plurality of equalization curves based on the speed of the vehicle, each of the plurality of equalization curves associated with the speed of the vehicle and each of the plurality of equalization curves defining a gain adjustment for one of a plurality of frequencies, and, for each curve of the plurality of equalization curves, applying the gain adjustment defined by the curve to one of the plurality of frequencies of the audio signal.

Abstract: Methods and systems for providing multi-zone climate control for a vehicle. One system includes a power source, a plurality of switches, a first zone heating/cooling device, a second zone heating/cooling device, and an electronic controller. The electronic controller is configured to operate the plurality of switches to supply current bi-directionally through the first zone heating/cooling device, bi-directionally through the second zone heating/cooling device, or bi-directionally through a series connection of the first zone heating/cooling device and the second zone heating/cooling device.
