Set Acceleration Thresholds
Use the Set Accelerations Thresholds dialog box to enter the rates of acceleration that define hard acceleration
and extreme acceleration. These thresholds help you monitor how hard the vehicle is being accelerated. Any
time the car’s acceleration exceeds these set limits, the event is logged in the Trip Report.
To set acceleration thresholds:
1. Choose Set Acceleration Thresholds... from the CarChip menu. The CarChip / Set Acceleration
Thresholds dialog box appears.
2. Enter your desired hard and extreme acceleration thresholds.
3. Select Default to use the software default threshold settings. The Default acceleration thresholds are:
0.28 and 0.48 G (US & Metric) and 2.8 and 4.7 m/s2 (S.I.).
4. Choose OK to save the new settings. Choose Cancel to exit the dialog box and retain the previous
settings.
Hard Acceleration Threshold
This is the lower of two acceleration thresholds you can set in CarChip.
The default hard acceleration threshold is:
U.S. = 0.28 G
Metric = 0.28 G
I.S. = 2.8 m/s
2
Extreme Acceleration Threshold
This is the acceleration rate which defines extreme acceleration. Set this rate at a level which you would not
expect a vehicle to exceed except during an emergency.
The default extreme acceleration threshold is:
U.S. = 0.48 G
Metric = 0.48 G
S.I. = 4.7 m/s
