Abstract
A system for adaptive control of an audio unit associated with a vehicle includes an electronic key fob, wherein the electronic key fob includes a sensor adapted to detect a motion event imposed on the electronic key fob by a user and a controller coupled to the sensor and configured to produce a control signal in response to the motion event. The system further includes a receiver installed in the vehicle and adapted to receive the control signal and another controller installed in the vehicle and interconnected between the receiver and the audio unit. The vehicle-based controller utilizes the control signal to adjust a volume of a sound produced by the audio unit.
Claims20
An electronic key fob for use with a vehicle comprising:
- a sensor configured to detect a motion event imposed on said electronic key fob by a user;
- and
- a controller coupled to said sensor and configured to produce a control signal in response to said motion event, said control signal being used to control an output of an audio unit associated with said vehicle.
A system for adaptive control of an audio unit associated with a vehicle comprising:
- electronic key fob for use with said vehicle, said electronic key fob including a sensor adapted to detect a motion event imposed on said electronic key fob by a user, a first controller coupled to said sensor and configured to produce a control signal in response to said motion event, and a transmitter coupled to said first controller for outputting said control signal;
- a receiver installed in said vehicle and adapted to receive said control signal;
- and
- a second controller installed in said vehicle and interconnected between said receiver and said audio unit, wherein said control signal is communicated from said receiver to said second controller and said second controller uses said control signal to adjust an output of said audio unit.
A method for adaptive control of an audio unit associated with a vehicle comprising:
- detecting a motion event imposed on an electronic key fob associated with said vehicle by a user;
- producing a control signal in response to said motion event;
- and
- adjusting an output of said audio unit in response to said control signal.
