1. A vehicle monitoring system comprising:
- a. an accelerometer for detecting a lateral acceleration of the vehicle;
b. a speed reduction activation circuit; and
c. a control device, wherein the control device receives a signal from the accelerometer and sends a signal to the speed reduction activation circuit based upon the signal from the accelerometer, wherein the control device sends a signal to the speed reduction activation circuit to reduce a speed of the vehicle based on a heading of the vehicle and if the lateral acceleration is greater than a threshold value.

20. A vehicle monitoring system comprising:
-
a. an accelerometer for detecting a gross lateral acceleration of the vehicle; b. a speed reduction activation circuit; and c. a control device, wherein the control device receives a signal from the accelerometer based on the gross lateral acceleration of the vehicle, wherein the control device calculates the absolute lateral acceleration based upon the gross acceleration value and sends a signal to the speed reduction activation circuit based upon the gross acceleration value, wherein the control device sends a signal to the speed reduction activation circuit to reduce a speed of the vehicle based on a heading of the vehicle and if the gross lateral acceleration is greater than a threshold value. - View Dependent Claims (21, 22, 23, 24, 25, 26, 27)
