1. What Is The Threshold Speed Formula?

The Threshold Speed under Normal Braking Mode formula calculates the maximum speed at which a vehicle can decelerate to a complete stop without activating the anti-lock braking system, based on the distance required for transition from main gear touchdown.

2. How Does The Calculator Work?

The calculator uses the formula:

Where:

• \( V_{th} \) — Threshold Speed under Normal Braking Mode (m/s)
• \( S_2 \) — Distance for Transition from Main Gear Touchdown (m)

Explanation: This formula establishes a relationship between the transition distance and the maximum safe braking speed, ensuring the vehicle can stop without engaging ABS.

3. Importance Of Threshold Speed Calculation

Details: Accurate threshold speed calculation is crucial for vehicle safety systems design, braking performance evaluation, and ensuring optimal stopping distances under normal braking conditions.

4. Using The Calculator

Tips: Enter the distance for transition from main gear touchdown in meters. The value must be valid (distance > 0).

5. Frequently Asked Questions (FAQ)
