CPC G06F 17/00 (2013.01) [G07C 5/008 (2013.01); G07C 5/0808 (2013.01)] | 15 Claims |
1. A computer-implemented, in-vehicle system for determining status of a stationary vehicle, comprising:
a three perpendicular component accelerometer located in the vehicle and configured to generate vehicle acceleration data representing changes in acceleration acting on the stationary vehicle;
a memory containing predefined acceleration patterns representing motion of the vehicle responsive to accelerations acting on the vehicle, including accelerations acting on the vehicle while stationary;
and 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 a determination of stationary vehicle status corresponding to the matched acceleration pattern, and
a telecommunications device in communication with the microprocessor wherein, in the event of an emergency, a number of vehicle entry and exit is automatically communicated to a rescue or emergency service; and
wherein said predefined vehicle acceleration patterns stored in memory for accelerations acting on the stationary vehicle comprise patterns representing motion of the vehicle responsive to vehicle entry and exit events.
