System and method for use of pattern recognition in assessing or monitoring vehicle status or operator driving behavior
A system and method which uses pattern recognition in assessing or monitoring a vehicle status and/or an operator's driving behavior. A vehicle, for use by an operator or driver, can be equipped with a data collection and assessment system. The system can comprise one or more data collection devices, e.g., accelerometers, which can be used to capture data and information, or otherwise measure vehicle actions. A pattern recognition module is configured with one or more defined operating patterns, each of which operating patterns reflects either a known change in vehicle status corresponding to, e.g., when a passenger has embarked or disembarked the vehicle, or a known vehicle operating or driving behavior. Information collected as events describing a current vehicle status or a current driving behavior can be compared with the known operating patterns.
1. A computer-implemented, in-vehicle system for determining stationary vehicle status and vehicle operator driving actions, comprising:
a three perpendicular component accelerometer located in the vehicle and configured to generate vehicle acceleration data representing changes in acceleration acting on the vehicle;
a memory containing predefined acceleration patterns representing motion of the vehicle responsive to accelerations acting on the vehicle, said predefined acceleration patterns including—
patterns representing vehicle motion responsive to vehicle occupant entry and exit events with respect to a stationary vehicle,
patterns representing vehicle motion responsive to vehicle accidents with respect to a stationary vehicle, and
patterns representing operator-based driving actions with respect to an operated vehicle,
wherein the predefined acceleration patterns are specific to one or more of an individual operator and a type of vehicle;
a microprocessor programmed to receive said vehicle acceleration data from the accelerometer and to compare, using pattern recognition, the predefined acceleration patterns to the vehicle acceleration data and, upon finding one or more pattern matches, to make determination of stationary vehicle status and vehicle operator driving actions corresponding to matched acceleration patterns; and
a telecommunications device disposed in the vehicle in communication with the microprocessor wherein, in the event of an emergency, determined vehicle status can be automatically communicated to a remote party.
2. The system of claim 1 , wherein said memory and microprocessor comprise a vehicle telematics system disposed within the vehicle.
3. The system of claim 1 , wherein said memory and microprocessor are remotely located external to the vehicle.
