INTRODUCTION New technology in Modern vehicles to enhance safety Anti Lock Braking System (ABS) Tilt angle (Roll angle) – crucial variable to determine motorcycle behavior Represents the amount of inclination to ensure the force balance
The technology uses a sensor to measure tilt angle at real-time Tilt angle is a by product of GPS but does not provide at real-time Optical sensors are suitable as technologically as well as economically for racing applications
TILT ANGLEDefinition : Angle represents the amount of inclination that the bike needs in order to ensure the force balance during the curved trajectory and hence to reach a steady state cornering condition .
Tilt angle ( ϕ )= arctan((d1 − d2)/L) d1 = Ho + L/2 tan (ϕ) d2 = Ho - L/2 tan (ϕ) Where, L :- Lateral displacement b/w the 2 distance sensors Ho :- Distance b/w each sensor and the ground when the bike axis is vertical d1&d2 :- Distance b/w the marked points and the ground
