Drift Angle Calculator

Calculate the drift angle of a vehicle based on speed, road curvature and friction coefficient

Input Parameters

Calculation Results

Calculation Formula

Drift Angle (δ) = arctan(α - β)

Where:
α = Road Curvature × Speed² × Friction
β = Road Curvature × Speed²

Result

Drift Angle: 0.00°
Critical Speed: 0.00 km/h

Drift Angle Calculator Usage Guide

Learn how to use the Drift Angle Calculator and understand its working principles

How to Use This Calculator

  1. Enter the vehicle's current speed in km/h
  2. Input the road curvature in 1/m (e.g., 0.001 for 1/1000m radius)
  3. Specify the road friction coefficient (typically between 0.7 for dry roads and 0.4 for wet roads)
  4. Click the "Calculate" button to compute the drift angle and critical speed

Understanding the Results

The drift angle shows how much the vehicle is偏离ing from a straight path due to road curvature at the given speed. If the actual speed exceeds the critical speed, the vehicle will start to drift.

Working Principle

The calculator uses the following physics-based formula:

Drift Angle (δ) = arctan(α - β)

Where:
α = Road Curvature × Speed² × Friction
β = Road Curvature × Speed²

The critical speed is the speed at which the drift angle becomes zero, meaning the vehicle can follow the curve perfectly without drifting.

Practical Applications

This calculator is useful for:

  • Understanding vehicle dynamics on curved roads
  • Planning safe speeds for different road conditions
  • Driver training and education
  • Vehicle performance analysis
