Title: DEVICE AND METHOD FOR IMPROVING THE PERFORMANCE OF AN ANTILOCK BRAKING AND ANTI-SLIP REGULATION OF A VEHICLE
Abstract:
Device for improving the performance of an antilock braking (ABS) and/or anti-slip regulation (ASR) and/or electronic stability control (ESC) system of a vehicle comprising at least a fluid-dynamic system for controlling the braking pressure composed of at least one standard ABS management control unit and a brake-servo unit and a fluid pressure pump, solenoid valves connected to pipes for oil or air and at least phonic wheels and tachometer sensors respectively present one for each wheel of the vehicle, the device comprises additional intelligent sensors associated with at least one of the braking pads acting upon the braking disk of each wheel in order to collect additional data and at least one dedicated ECU control unit for managing said additional data and interacting with at least said ABS control unit. The method consists in detecting, by means of the pad and the dedicated control unit, the actual value of the tire-ground coefficient of friction that is constantly updated during braking using the braking torque data derived from the braking pad in order to adjust the braking pressure profile to the value of the actual coefficient of friction present between the tire and the ground during the braking of the vehicle.
