METHOD FOR DATA COMMUNICATION BETWEEN A VEHICLE AND A REMOTETERMINAL

摘要

In one embodiment there is disclosed an apparatus for validating with minima l delay data transmitted to a data bus of a vehicle from a remote location and data transmitted from the data bus of the vehicle to a remote location. The apparatus comprises a loca l transceiver in operable electrical communication with the data bus of the vehicle and suitable to transmit data from the data bus to a remote location and receive data-transmitted to the data bus from a remote location. The apparatus also comprises a local processor in electrica l communication with the local transceiver and the data bus of the vehicle. Data output by t he local processor to the data bus and data transmitted by the local transceiver to a remote location are also received by the local processor as false data and the local processor analyz es data received by the local processor and prevents propagation of false data to either the dat a bus or to the remote location. The local processor analyzes the data one bit at a time suc h that data may be transmitted from and to the data bus with minimal delay.
