Abstract :
This paper describes a fault tolerant steer-by-wire road wheel control system. With dual motor, dual microcontroller architecture this system has the capability to tolerate single point failure without degrading the control system performance. The arbitration bus, mechanical arrangement of motors, and the developed control algorithm allow the system to reconfigure itself automatically in the event of a single point fault, and assure a smooth reconfiguration procedure. The experimental result illustrates the effectiveness of the proposed system.
