the configuration file generation module is configured to generate a routing information configuration file, create a file with a writable arxml format file attribute through a matlab tool, and write the whole frame of routing configuration information and the signal routing configuration information into the arxml.
7. The automatic generation device of the controller software routing information configuration file based on the Autosar architecture as claimed in claim 6, wherein the parsing, by the identification unit, of the entire frame of routing information in the CAN protocol specifically includes: extracting original information in a summary table to a structure ALL _ OverView, wherein structure elements comprise network segments, nodes, periods, sending IDs, lengths and receiving nodes; carrying out de-spaceization processing on information in a structure, finding out messages sent by ALL GWs, storing the messages into a structure ALL _ GW _ Overview, then carrying out traversal query on the messages sent by ALL the found GWs in the ALL _ Overview according to ID content, if a sending node with the same ID content and non-GW is queried, considering the message with the ID as a whole-frame routing message, and storing corresponding information in MsgrouteInfo, wherein the structure comprises information including a sending network segment, a sending node, a period, an ID, a length and a receiving node; otherwise, the ID message is an information routing message, corresponding information is stored in SigRouteInfo _ Overview, and the structure comprises information including a sending network segment, a sending node, a period, an ID, a length and a receiving node.
8. The automatic generation method for the controller software routing information configuration file based on the Autosar architecture as claimed in claim 7, wherein the analyzing the signal routing information in the CAN protocol by the identification unit specifically includes: extracting original information in a protocol Matrix and storing the original information in a structural body Tab _ Matrix0, wherein elements contained in the structural body comprise a sending network segment, a sending node, a signal name, a sending ID, routing information and a receiving node; in Tab _ Matrix0, finding out elements with the same ID and the same network segment as those in SigRouteInfo _ Overview, storing all found message information meeting the conditions into a structure SigRouteInfo _ Temp, wherein the elements contained in the structure comprise a sending network segment, a sending node, a signal name, a sending ID and routing information, and finally removing invalid routing information in the SigRouteInfo _ Temp and storing the invalid routing information in the structure SigRouteInfo, wherein the elements comprise the sending network segment, the sending node, the signal name, the sending ID and the routing information.
9. The automatic generation device of the controller software routing information configuration file based on the Autosar architecture according to claim 7 or 8, wherein the configuring, by the first configuration unit, of the entire frame of routing information in the PduR module specifically includes: firstly, creating an arxml file, writing the contents of a header part according to an arxml file format specified by autosar, searching a sending node in a whole frame routing structure MsgrouteInfo as a GW message, if yes, indicating that the message is a Source message, and storing the information into a structure MsgrouteInfo _ Source, wherein structural elements comprise a sending network segment, a sending node, a period, a sending ID, a length and routing information; otherwise, indicating that the message is a target message, and storing the information into a structure MsgrouteInfo _ Destination, wherein the structure elements comprise a sending network segment, a sending node, a period, a sending ID, a length and routing information; traversing the MsgrouteInfo _ Source in the structure according to the ID to obtain Source message information required by writing an arxml file, combining character segments, and writing the Source message information into the arxml file according to a Pdu module format in autosar; then, searching a message with the same ID as that in the current source structure body in the MsgrouteInfo _ Destination of the structure body to obtain the information of a corresponding target message, combining character segments, and writing the target information into an arxml file according to a Pdu module format in autosar; and finally, writing the content of the tail part of the arxml file at the end of the file according to the autosar format.
10. The method according to claim 9, wherein the configuring, by the second configuring unit, the signal routing information in the Com module specifically includes: firstly, creating an arxml file, writing the head part content of the file according to an autosar format, then obtaining a source network segment, a source sender and a source ID of a signal from an element RouteMark in a signal routing structure Sigrouteinfo, combining character segments, then writing source information and target information into the arxml file according to a COM module format in the autosar, and finally writing the tail part content of the arxml file in the autosar format.
