Motorcycle Lean Angle Calculation

In summary, the conversation discusses the calculation of motorcycle lean angle using various inputs such as wheel speed, a sensor fixed near the COG, and gyro readings. The issue of gyro drift is mentioned and a potential solution involving the road slope angle is proposed. The need for the barycenter, radius, and speed is also mentioned, along with the suggestion to draw a force diagram. The angle can affect the barycenter and friction.

I would like to calculate motorcycle lean angle. I have various inputs available including front and rear wheel speed, 3 axis of G form a sensor fixed near the COG of the bike, gyro in 3 planes. The gyro drifts as all gyros do so a simple integration of the gyro rate of change is unsatisfactory. A second interesting additional calculation would be to include the road slope angle in the equation so that the angle of the bike is directly in relation to the slope of the road. Any help would be greatly appreciated.

You need the barycenter, radius and speed. Then draw a force diagram with gravitational, possibly frictional, centrifugal, and centripetal force. The angle basically lowers the barycenter and changes friction.
 

Related to Motorcycle Lean Angle Calculation

1. What is motorcycle lean angle calculation?

Motorcycle lean angle calculation is a method used to determine the angle at which a motorcycle is leaning while in motion. It takes into account the speed, acceleration, and weight distribution of the bike to calculate the angle.

2. Why is motorcycle lean angle calculation important?

Motorcycle lean angle calculation is important because it can help riders understand their bike's handling and performance. It can also be used to analyze and improve riding techniques for better control and safety.

3. How is motorcycle lean angle calculated?

Motorcycle lean angle is calculated using the formula: tanθ = (v^2/r)/g, where θ is the lean angle, v is the velocity of the motorcycle, r is the radius of the turn, and g is the gravitational acceleration.

4. What factors can affect motorcycle lean angle?

The main factors that can affect motorcycle lean angle include speed, acceleration, weight distribution, road conditions, and the rider's skill and technique. Wind and other external forces can also impact the bike's lean angle.

5. Is there a maximum safe lean angle for motorcycles?

There is no specific maximum safe lean angle for motorcycles as it can vary depending on the type of bike, road conditions, and rider's skill. However, it is generally recommended to stay within a 45-degree lean angle for most street motorcycles to maintain stability and control.
