Patent ID: 8436723

Claim:
A vehicle monitoring system comprising: a plurality of noise and vibration level sensors for determining noise and vibration levels in various locations in a vehicle during operation of the vehicle and generating output signals indicative of the noise and vibration levels, at least one of said noise or vibration level sensors located in the passenger compartment of the vehicle; a control unit coupled with said noise and vibration level sensors for receiving said output signal from said noise and vibration level sensors, wherein said control unit is capable of receiving said output signals and comparing said output signals from said noise and vibration level sensors with a predetermined value and storing information from said noise and vibration level sensors when a predetermined value is exceeded and for storing information from said noise and vibration level sensors at a predetermined interval; an engine control unit coupled with said control unit wherein said control unit coordinating the output signal of from the noise and vibration level sensors with information from said engine control unit to thereby build a database of the noise and vibration levels coordinated with the information from said engine control unit of the vehicle over time.
