Abstract :
Steer-by-wire system of electric vehicle must meet the real-time and reliability requirements. An approach in how to estimate the reliability of steer-by-wire system considering the delay caused by network transmission errors is proposed. In the paper, a distributed architecture of steer-by-wire system is researched to analyze the delay time of the system, and design the TDMA slots of FlexRay bus. In addition, the reliability of the system is calculated. The maximum tolerable response time of the system is performed by using Matlab/Simulink and other parameters of the system based on our experiment platform. The results show that when the probability of losing one cycle is less than 0.1, the reliability of the system achieves the design goal. The approach in this work can be taken as a reference for designing steer-by-wire system of electric vehicle.
