With a Samsara Vehicle Gateway (VG) comes the ability to monitor harsh events that occur to all vehicles in a fleet.
How does a VG determine a harsh event?
The VG determines a harsh event using a built-in accelerometer that monitors for harsh braking, acceleration, and cornering. The harsh event parameters are different for different vehicle type. By default, the vehicle type is inferred by the VG, but can also be set manually from the vehicle settings in the dashboard.
For more information about the harsh event parameter, view the Change Harsh Event Sensitivity article.
A harsh event is triggered by a handful of different sensors, but a simplification of its triggers can be described by discussing gravitational force (g) thresholds, as follows:
- Passenger Car: ~0.6 g (Least sensitive)
- Light Truck: ~0.4 g
- Heavy Duty: ~0.35 g (Most sensitive)
What happens when a harsh event occurs?
When a harsh event occurs, the VG records the time, driver, vehicle, and location of the event as well as additional data about speed, direction, and other interesting data points.
The event can then be found in the:
- Safety Report
- Harsh Event Alert
- If a Samsara camera is also installed, it will automatically upload a 20-second video of the harsh event that can be reviewed in the Safety Inbox.
