Abstract: A sound modification system and a method of managing sound in a vehicle. The system includes an active noise reduction (ANR) controller, an engine sound enhancement (ESE) controller and a sound modification controller. When the vehicle is in a steady state driving condition, the sound modification controller activates the ANR controller and deactivates the ESE controller. In contrast, when the vehicle is in a non-steady state driving condition, the sound modification controller activates the ESE controller and deactivates the ANR controller. Preferably, when the vehicle switches between the steady state and non-steady state driving conditions, the sound modification controller activates and deactivates the ANR and ESE controllers at a rate that is not noticeable to a human. In summary, the system utilizes the ANR and ESE controllers to achieve an optimal passenger cabin experience for the driver during any driving condition.

Abstract: A vehicle impact sensing system for detecting impact events to a vehicle, and allowing deployment decisions of passive restraint devices based on information gathered and relayed regarding such impact events. The sensing system includes one or more sensor elements capable of directly detecting vehicle deformation occurring as a consequence of the impact event. The sensor elements generate an output that varies upon deformation of the element. The sensor elements are in communication with a restraints control module. Upon deformation of the sensor element, the control module receives impact signals from the sensor elements based upon the altered output, and discriminates between impact events that warrant deployment of a passive restraint, such as a side air bag, and those that do not. The control module utilizes information gathered from the sensor elements to make deployment decisions, such as which restraint to deploy and the appropriate degree of deployment.
