About g-force
Gravitational force (g-force) is a measure of acceleration and deacceleration based on the values for the x, y, and z axes. When a vehicle accelerates quickly or turns suddenly, more g-force is felt. A higher g-force can indicate risky driving.
There are three g-force events
- G-sensor regular - the g-force of the vehicle is higher than it should be
- G-sensor high - the g-force of the vehicle is higher than it should be, and is even higher than the level that triggers a g-sensor normal event
- Possible accident - the g-force of the vehicle is very high, indicating a possible collision
The thresholds for these events are described in the following table
Event | Vehicle | X-axis value | Y-axis value | Z-axis value |
G-sensor regular | Private vehicle | 750 | 750 | 2000 |
Van | 950 | 950 | 2000 | |
Trailer | 1150 | 1150 | 2000 | |
G-sensor high | Private vehicle | 1050 | 1050 | 2300 |
Van | 1200 | 1200 | 2300 | |
Trailer | 1450 | 1450 | 2000 | |
Possible accident | Private vehicle, van, trailer | 2500 | 2500 | 2500 |
The X, Y, and Z-axes values represent the following measurements
Axis | Positive value | Negative value |
X | Acceleration | Deceleration |
Y | Left | Right |
Z | Up | Down |
