- Summary:
- Sports Utility Vehicles (SUVs) Braking performance is a critical parameter, and it is described by the measure of stopping distance and stability of the vehicle at a specified speed. When it comes to electric vehicles, balancing tyre performance parameters like RRc, traction, wear, ride and handling, weight and NVH is challenging due to higher axle weights, higher moment of inertia and high instant torque delivery. This study presents the braking performances of EV-intended tyres at various contact surfaces in both dry and wet conditions. Impact of tyre design attributes like tyre tread pattern, contact patch, tread compound, tyre carcass construction and characteristics studied on 3 different tyres including ultra-high-performance tyres on braking performances. This paper contains the study and analysis of 1) Footprint analysis concerning the shape of the contact patch, pressure distribution, land-sea ratio, and contact area 2)Tyre tread design such as NSD, grooves, ribs and sipes design and pitch length 3) Compound property studies like hardness, modulus, tensile strength, tear strength and elongation at break 4)Materials like polymer blend, filler ratio and new-gen materials 5)Tyre performance characteristics which are contributing to vehicle stability like lateral stiffness, longitudinal stiffness, dynamic stiffness and mu slip curves and 6) Longitudinal and lateral forces at various speed conditions with CAE Simulations.BEV requires low rolling resistance for improving vehicle range and which calls for reducing the hysteresis of tyre tread compound which affect vehicle barking performance at wet surface and it should be compensated by adjusting other design parameters.Mu slip curve very important characteristics for designing brakes system to get peak mu and programming software for ABS system
