| Abstract: | FlexRay will probably become the next generation vehicle network standard. This paper presents a FlexRay based solution to a brake-by-wire pre-prototype system to investigate its application prospect in a x-by-wire system. This pre-prototype comprises 4 speed sensors, 3 ECU units, I step motor and 1 footbrake pedal position sensor. The development flow follows a V model. We implement fault-tolerant and real-time high-speed dual channels communication in its operation. Result shows that the system has better data transmission stability and reliability than other bus based system, and that brake effect is obvious. |
