| Abstract: | WLAN/CAN bridges in vehicles can facilitate connections among vehicles and the control center in the cluster of engineering vehicles, thus the whole cluster will be so well communicated and collaborated that it can perform better control decision to get more benefit and efficiency. Three schemes of the WLAN/CAN bridge are involved in this thesis, followed by the design and implementation of the WLAN/CAN bridge based on embedded Linux system. GSM short messages are used as a backup communication route against the low signal quality of WLAN, by which the control messages of high priority can be transmitted to enhance the wireless communication quality and capability. |
