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, and sensitivity can be changed as follows:
- Passenger Car (Least sensitive)
- Light Truck
- Heavy Duty (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.
Adding and Removing Harsh Event Labels
An accurate and detailed Safety Inbox is important to productive safety review and driver coaching. To that aim, fleet administrators can add and remove automated labels on events in their Safety Inbox.
Removing automated labels or adding custom labels helps improve Samsara’s automatic detection of these types of harsh events.
To add or remove a label, navigate to the Safety Inbox: Fleet > Reports > Safety Inbox and select any event.
Labels are listed below the event’s footage and adjacent to the date. You can remove a label from the event by clicking on the X.
You can add a label to the event by clicking “Add” and selecting an option from the dropdown.
Each harsh event can only be associated with one of the following labels: Harsh Acceleration, Harsh Brake, Harsh Turn, or Crash.
Distracted can be used in conjunction with the other labels.
Commenting on Harsh Events
As a Fleet Administrator, you can add comments to a harsh event in your Safety Inbox. The comment section will allow you to leave notes for a later follow-up or clarification on the harsh event.
Users must have full admin permissions with Dash Cam access in order to write comments. Full and read-only admins with Dash Cam access will also be able to view previously made comments.
Navigate to the Safety Inbox: Fleet > Reports > Safety Inbox and select any harsh event report.
Below the video and details of the harsh event, you will find an Activity section in which you will be able to leave comments.
The most recent comments will be displayed at the top of the thread.
