Type: article
Abstract: A brake pedal simulator in a Brake-by-Wire system is studied for fault tolerant control of the brake pedal signals. This study is conducted for the pedal simulator installed with a sensor that generates two analogue signals. Several realistic fault modes recognized by automotive experts have been analyzed. To solve the fault modes, we propose a fault tolerant output selector that can handle transient, intermittent, or permanent faults. The fault tolerant output selector, based on a fault detection algorithm, uses the BLS(brake light switch) signal and the Acc(acceleration pedal) signal to find faults and isolate them. To confirm the system performance, the fault modes were simulated. The result showed the reliability and safety of the pedal simulator for dealing with unexpected faults.
