Abstract

An automotive vehicle includes a first movable window selectively covering a first cabin opening and a second movable window selectively covering a second cabin opening. A first actuator is configuredto selectively actuate the first movable window and a second actuator is configured to selectively actuate the second movable window. A controller is in communication with a sensor disposed in the cabin and with an HMI configured to receive a window open request from an operator. The controller is configured to, in response to the window open request, control the first actuator to actuate the first movable window from a closed position to an open position, and in response to a signal from the sensor indicating pressure variations exceeding a predefined threshold with the first movable windowin the first open position, automatically control the second actuator to actuate the second movable window in an open direction.

Description

technical field [0001] The present disclosure relates to motor vehicles, and more particularly, to window assemblies for motor vehicles. Background technique [0002] Motor vehicles generally have a cabin in which occupants can reside. Such compartments typically have one or more windows that can be raised and lowered by the occupant. However, lowering the windows while the vehicle is in motion may cause chattering or Helmholtz resonance effects within the vehicle. As shown in FIG. 1 , as the air passes through an opening, such as an open side window, a vortex is formed. When a vortex hits the trailing edge of an opening, such as the B-pillar in Figure 1, the vortex induces a pressure wave in the cabin of the vehicle. The rate at which these pressure waves occur is based on the speed of the vehicle relative to the air. Therefore, the pressure wave may be close to the resonance point at some vehicle speeds. The intensity of sound and pressure near such resonance points m...
