If the authentication is successful, the subsequent information transmission operation is continued, if the authentication is failed, the non-original module is determined to be an illegal node, and the data information in the non-original module is prohibited from being uploaded to the original module and the CAN of the original module, so that the data safety in the original module is guaranteed.
S740, if the authentication is successful, the gateway module forwards data required by the vehicle non-original module to a controller area network of the non-original module;
s750, a non-original-mounted module receives data required by the vehicle non-original-mounted module, wherein the data are transmitted by a controller local area network of the non-original-mounted module;
and S760, the non-original module executes corresponding functions according to data required by the vehicle non-original module.
Further, referring to fig. 11, the method further includes:
s1110, the non-original module sends data executed by the non-original function to a gateway module through a controller local area network of the non-original module;
s1120 if the gateway module successfully authenticates the non-native module, the gateway module forwards the data executed by the non-native function to a controller area network of the native module;
s1130 the original module receives data, which is transmitted by the controller area network of the original module and executed by the non-original function.
The embodiment of the invention provides a network control method of a non-original module, which comprises the following steps: when the original module sends data to the non-original module or the non-original module sends data to the original module, the gateway module needs to authenticate the non-original module, data transmission can be continued when authentication is successful, and data transmission of the non-original module to the original module is forbidden when authentication is unsuccessful. The method has the advantages that the control local area network of the non-original module is separated, the mutual interference between the non-original module and the original module is avoided, the communication quality of the control local area network is guaranteed, and the safety of data transmission is guaranteed in a mode of authenticating the non-original module.
