A FlexRay/CAN Vehicle Communication Network for an Anti-Lock Braking System Based on X-by-Wire Technology

In this study, a new FlexRay vehicle communication network was integrated with the current mainstream network CAN. The FlexRay network was connected by a hybrid topology to a brake-bywire node to implement an x-by-wire control system. The CarSim software was combined with LabVIEW and interface cards to construct and test the active safety of a simulated car. An anti-lock braking system (ABS) node based on FlexRay communication transmitted vehicle speed through the FlexRay network immediately. Moreover, a FlexRay-monitoring node monitored the ABS simultaneously. ABS data were transferred to the CAN network via a FlexRay/CAN gateway. Furthermore, an ABS-monitoring application was developed for an Android phone using Bluetooth to transmit data on both wheel speeds and brake slip values.
