## Abstract

A system for automatically synchronizing window openings and closings of multiple windows of a vehicle. The system includes a first actuator and a second actuator configured to move a first window and a second window to respective closed positions. The system includes a window control unit configured to receive, at a first time, an indication to close the first window at a first closing rate. The window control unit is configured to receive, at a second time, an indication to close the second window at a second closing rate. The window control unit is configured to adjust at least one of the first closing rate or the second closing rate, from a standard rate to an adjusted rate, when the first time and the second time are within a threshold time, such that the first window and the second window achieve their respective closed positions simultaneously.

wherein the threshold time difference and the threshold window position difference are based on the user preference data.

### Claim 7 (depends on 1)

The system of claim 1, further comprising:
an air pressure sensor configured to detect air pressure data; and
an air control unit configured to:
detect, based on the air pressure data, a change in air pressure in response to the closing of the first window and the second window, and
adjust air pressure within the vehicle when the change in air pressure is detected.

### Claim 8

A vehicle having a first window and a second window, the vehicle comprising:
a first actuator configured to move the first window to a first window closed position;
