1. A vehicle monitoring device for performing a method of monitoring the operation of a vehicle, the method comprising:
- monitoring one or more forces applied to a vehicle along one or more axes during operation of the vehicle;
monitoring observed vehicle movement in response to the one or more forces;
comparing the observed vehicle movement to a profile of expected vehicle movement; and
identifying variations between the observed vehicle movement and the expected vehicle movement.

10. One or more computer-readable media having computer-usable instructions stored thereon for performing a method of monitoring the operation of a vehicle, the method comprising:
-
establishing a baseline profile of the operation of a vehicle, the baseline profile comprising one or more ranges of vehicle movement along or about at least one axis; monitoring movement of the vehicle in response to forces acting upon the vehicle after a baseline period; and identifying deviations between the vehicle movement and the baseline profile after the baseline period. - View Dependent Claims (11, 12, 13, 14, 15, 16, 17, 18)

19. A method for identifying a vehicle maintenance problem, comprising:
-
observing, by a vehicle monitoring device, vertical oscillations of a vehicle; comparing the vertical oscillations to thresholds in a vehicle performance profile; identifying occurrences of vertical oscillations that exceed the thresholds; and using one or more of a number of oscillation cycles, a range of vertical oscillations, and a damping of the vertical oscillations to identify the vehicle maintenance problem. - View Dependent Claims (20)

21. A method for identifying vehicle maintenance problems, comprising:
-
observing, by a vehicle monitoring device, rolling movement of a vehicle during turns; comparing the rolling movement to thresholds in a vehicle performance profile; identifying occurrences of rolling movement that exceed the thresholds; and identifying vehicle maintenance problems based upon the rolling movement that exceeds the thresholds. - View Dependent Claims (22)

23. A driver alerting device comprising:
-
a vehicle monitoring device; an output interface; and a processor in communication with the vehicle monitoring device and the output interface, such that the processor is operable to obtain vehicle movement information in at least one direction in response to a force applied to the vehicle, to compare the vehicle movement information to a threshold, and to alert the driver when the vehicle acceleration information exceeds the threshold using the output interface. - View Dependent Claims (24, 25, 26, 27, 28, 29, 30, 31, 32, 33, 34, 35, 36)
