Driver behaviour monitoring uses accelerometer data and speed readings to detect specific driving events: harsh braking, rapid acceleration, sharp cornering, and excessive speeding. Each event is logged with timestamp, location, and severity – and combined into a per-driver safety score.
Fleet managers use DBM data in three ways: real-time in-cab alerts (a buzzer when a harsh event is detected), post-trip coaching (reviewing score history with the driver), and trend reporting (tracking whether scores improve after coaching).
- Harsh braking – deceleration above a configurable G threshold
- Rapid acceleration – acceleration above threshold, linked to fuel waste
- Cornering – lateral G above threshold, linked to tyre wear and rollover risk
- Speeding – actual speed vs posted limit where map data is available
- Idling – engine running with vehicle stationary beyond a time threshold
