A method and system controls active shock absorbers in an off road vehicle. X- Y- and Z-signals from at least one accelerometer sensor are received and analyzed in an ECU to make a vehicle travel status assessment. A recent history of Y-signals is analyzed to determine a vibration frequency of the vehicle relative to its natural suspension frequency. By using either a) two 3-axis accelerometer sensors are positioned high on the frame along a centerline of the vehicle, or b) a single accelerometer sensor is positioned just underneath the driver's seat, the cost of implementation is reduced while protecting the accelerometer sensor(s) from damage. In addition to vibration frequency, the ECU can determine the onset and conclusion an acceleration event, a deceleration event, a cornering event, or a jumping event, outputting signals used to adjust the damping coefficient of each of the active shock absorbers.
