摘要
比较BST(Bosch Siemens Temic)、SBW(safe-by-wire)和DSI(distributed system interface)3种新型汽车安全总线标准.定义BST总线接口芯片的各功能子模块,用VHDL硬件描述语言设计此接口电路.仿真结果表明,总线接口芯片能满足传感器在BST总线协议下通信设计要求.
In order to reduce the costs of wiring used in automobiles and improve the performance of the failure detection and diagnosis, several bus systems were developed. Three new leading bus systems, namely BST (Bosch Siemens Temic), SBW (safe-by-wire) and DSI (distributed system interface), were analyzed and compared in terms of analog and digital performance. BST was finally chosen as the standard bus protocol for vehicle safety to implement the interface IC. The functions of submodules were defined and the chip IC was designed in VHDL. The simulation results have demostrated that this digital interface chip is able to work properly and meet the design specifications of the data communication of sensors with BST protocol.
