Harsh Braking & Acceleration (G-Force)
What is it?
Harsh braking and harsh acceleration refer to aggressive driving maneuvers that generate high G-forces. A G-force is a measure of acceleration or deceleration relative to the force of gravity.
How it works
Telematics systems measure these events using accelerometers. When you slam on the brakes or floor the accelerator, the vehicle experiences a sudden spike in G-force. These events are flagged as "harsh" because they indicate inefficient, potentially unsafe driving that wastes energy and puts excessive strain on the vehicle's components.
Why it matters
Harsh acceleration requires a massive surge of power, draining the battery rapidly. Harsh braking means you are converting kinetic energy into useless heat via the brake pads, rather than recovering it smoothly through regenerative braking. Minimizing these events is crucial for extending range and reducing maintenance costs.
The Aximote Advantage
Because Aximote runs natively in the car, it has access to highly accurate, high-frequency telemetry data. It detects harsh braking and acceleration events with precision, without the false positives common in smartphone apps (which can be triggered simply by the phone moving in its holder). Aximote highlights these events in your trip logs, helping you identify and eliminate energy-wasting habits.
