VEHICLE MONITORING SYSTEM AND VEHICLE MONITORING METHOD

摘要

A vehicle monitoring system includes a positioning module, a gravity acceleration sensor, and a position determining module. The positioning module receives data transmitted from a global positioning system satellite to obtain a position of a vehicle or of a device which is co-positional with the vehicle. The gravity acceleration sensor senses acceleration of the vehicle. When the gravity acceleration of the vehicle is zero, the position determining module determines the last received position data as position of the vehicle. When the gravity acceleration of the vehicle is not zero, the position determining module can be used to form a relationship between current position and a speed limit applicable to the present position of the vehicle and issue warnings as appropriate. A vehicle monitoring method is also provided.

1. A vehicle monitoring system comprising:
a positioning module configured to receive data transmitted from a global positioning system satellite to obtain a position; an acceleration sensor configured to sense acceleration of the vehicle; and a position determining module configured to, when the gravity acceleration of the vehicle is zero, determine the last received position of the vehicle to obtain the present position of the vehicle and when the gravity acceleration of the vehicle is not zero, determine currently received position data as position of the vehicle to obtain the present position of the vehicle.
