68431 - Improved Anti-Lock Braking System With Real-Time Friction Detection to Maximize Vehicle Performance 

Nowadays, advanced driver assistance systems play a fundamental role in the automotive field in order to improve vehicle safety and drivability; their capability to reduce the accidents rate and severity was widely demonstrated, but these assistance systems could also be employed to improve vehicle performance if incorporated with other control logics, supporting the driver in the driving task. This work presents an evolved version of the anti-lock braking system, obtained thanks to the combined use of a single-track vehicle model, capable to estimate the actual tire-road friction coefficient in a wide range of different environmental conditions, and a real-time estimator of the maximum achievable friction value based on a Magic Formula tire model with a slip-slope approach. With the presented ABS, virtually tested in several conditions, it is possible to reduce the braking distance with the final aim of reducing the braking time and, in this way, improving the vehicle performance. Such results are obtained in a simulation environment, carry out a vehicle in a braking manoeuvre on a straight road, before approaching a corner. Finally, the obtained results are compared with a vehicle performing the same manoeuvre involving only a traditional anti-lock braking system in order to demonstrate the effectiveness of the proposed solution.
