Slip Angle Calculator

Slip angle of the tyre (α):

Steering angle (δ):

Lateral velocity of the vehicle (v_y):

Forward velocity of the vehicle (v):

How This Is Calculated

$$ \alpha = \delta - \frac{v_y}{v} $$ where:

α = Slip angle of the tyre (°)

δ = Steering angle (°)

v_y = Lateral velocity of the vehicle (m/s)

v = Forward velocity of the vehicle (m/s)

Assumptions

The relationship between the lateral force and slip angle is linear.
The cornering stiffness remains constant over the range of slip angles considered.
Tyre characateristics are ideal.
Road surface and load effects are neglected.
