Abstract
A method of generating vehicle noise includes recognizing a geographic location requiring a minimum operating noise level of the vehicle, and notifying the telematics unit operatively associated with the vehicle that a then-current location of the vehicle coincides with the recognized geographic location. When the telematics unit is notified, the method further includes triggering a noise generator to generate an amount of noise external to the vehicle, where the generated noise is sufficient to reach the minimum operating noise level.
Claims24
A method of generating vehicle noise, the method comprising:
- via a call center, recognizing a geographic location requiring a minimum operating noise level of the vehicle;
- notifying a telematics unit operatively associated with the vehicle that a then-current location of the vehicle coincides with the recognized geographic location, the telematics unit being in selective and operative communication with the call center;
- and
- when the telematics unit is notified, triggering, via the telematics unit, a noise generator to generate an amount of noise external to the vehicle, the generated noise sufficient to reach the minimum operating noise level.

A method of generating vehicle noise, comprising:
- recognizing a geographic location requiring a minimum operating noise level of the vehicle by determining, at a call center, the recognized geographic location using data collected from at least one other vehicle;
- transmitting, from the call center to the telematics unit, the recognized geographic location based on the collected data;
- notifying a telematics unit operatively associated with the vehicle that a then-current location of the vehicle coincides with the recognized geographic location;
- and
- when the telematics unit is notified, triggering, via the telematics unit, a noise generator to generate an amount of noise external to the vehicle, the generated noise sufficient to reach the minimum operating noise level.

A noise generating system for a vehicle, the system comprising:
- a call center;
- a telematics unit in selective and operative communication with the call center, the telematics unit to receive, from the call center, one of i) a recognized geographic location retrieved from a database at the call center or ii) a planned route including the recognized geographic location, the recognized geographic location requiring a minimum operating noise level of the vehicle;
- and
- a noise generator in selective and operative communication with the telematics unit, the noise generator configured to generate an amount of noise external to the vehicle when the telematics unit is notified that the then-current location of the vehicle coincides with the recognized geographic location, wherein the generated noise is sufficient to reach the minimum operating noise level.

A method of generating vehicle noise, comprising:
- recognizing a geographic location by an other vehicle, the recognized geographic location requiring a minimum operating noise level of the vehicle;
- broadcasting the recognized geographic location to the vehicle;
- storing the broadcasted recognized geographic location in a memory operatively associated with a telematics unit operatively associated with the vehicle;
- identifying, via the telematics unit, when a then-current location of the vehicle coincides with the recognized geographic location by comparing the then-current location of the vehicle with the broadcasted recognized geographic location, thereby notifying the telematics unit that the then-current location of the vehicle coincides with the recognized geographic location;
- and
- when the telematics unit is notified, triggering, via the telematics unit, a noise generator to generate an amount of noise external to the vehicle, the generated noise sufficient to reach the minimum operating noise level.

A noise generating system for a vehicle, the system comprising:
- a call center;
- a telematics unit in selective and operative communication with the call center;
- a noise generator in selective and operative communication with the telematics unit, the noise generator configured to generate an amount of noise external to the vehicle when the telematics unit is notified that a then-current location of the vehicle coincides with a recognized geographic location requiring a minimum operating noise level of the vehicle, wherein the generated noise is sufficient to reach the minimum operating noise level;
- and
- at least one other vehicle configured to obtain data related to at least one geographic location, wherein the at least one geographic location is the recognized geographic location or an other geographic location;
- wherein the call center is in selective and operative communication with the other vehicle and with the telematics unit, the call center being configured to i) collect the data obtained by the at least one other vehicle, ii) determine that the at least one geographic location is a recognized geographic location using the collected data, and iii) determine the minimum operating noise level corresponding to the recognized geographic location;
- and wherein the telematics unit is further configured to receive a transmission of the recognized geographic location and the minimum operating noise level from the call center.
