The dimensions of the vehicle are used to sense impending rollover of the vehicle. The
suspension properties or oscillation frequency detail is used to estimate the current load of the
vehicle. As the load of the vehicle is increased, the centre of gravity point will also increase
correspondingly. There are three methods used to estimate the height of the centre of gravity
point:
C.g. Calc. Method
Description
Mixed Freight
It is assumed that 70% of the payload is located at the
bottom half of the vehicle, and 30% of the payload is
located in the top half. The maximum height of c.g.
point is therefore around 40% of the maximum height of
the payload.
Uniform Density
The height of the c.g. point rises linearly with payload.
The maximum height of the c.g. point is reached to the
maximum height of the vehicle when the payload is at
maximum.
Fixed c.g. height
The c.g. point defined by the user and always remains
constant. Changes in vehicle mass will not change the
value of c.g. height.

The reference chassis value is used to calculate the rating of shock absorbers.
