DEVELOPMENT OF AN ANTI-LOCK BRAKE SYSTEM FOR MOTORCYCLE

An Anti-Lock Brake System (ABS) system is developed for motorcycles us ing different control laws to improve the safety during emergent braki ng conditions. The mechanical design problem is first investigated so as to modify a scooter to be equipped with the proposed ABS brake syst em and to set up experimental test stand. For ABS control, the slip co ntrol, P1R3, and P2R4 methods are used to implement the controller usi ng an Intel 80196KC single chip microcomputer. The hardware-in-the-loo p (HITL) simulation is also performed in PC to check the performance i n various road conditions including dry and wet roads. It is found exp erimentally that both P1R3 and P2R4 can both achieve ABS function, but P2R4 performs more desirably than P1R3 method.
