Abstract

The invention relates to a vehicle-mounted Ethernet system and a vehicle. The vehicle-mounted Ethernet system includes a vehicle controller equipped with an Ethernet communication module, a gateway, a diagnostic interface and a first vehicle-mounted device; the vehicle-mounted controller is connected with the gateway and the first vehicle-mounted device through the bus architecture of Ethernet control automation technology EtherCAT; the diagnostic interface is connected with the gateway through the bus architecture of the EtherCAT; and the vehicle controller regularly broadcasts clock messages to the gateway, the diagnostic interface and the first vehicle-mounted device. With the vehicle-mounted Ethernet system and the vehicle of the invention adopted, the problem of dynamic delay which is caused by a condition that a switch is used as a monitoring port in an existing vehicle-mounted Ethernet system, and a problem that a measuring tool cannot be applied to an existing vehicle bus system can be solved.

Description

technical field [0001] The invention relates to the technical field of automobiles, in particular to a vehicle-mounted Ethernet system and a vehicle. Background technique [0002] The development and support of the automotive network requires effective testing and monitoring methods to make the entire vehicle network transparent, otherwise the application of the entire network is not feasible. Traditional automotive Ethernet uses a port on the switch of the Ethernet system as a monitoring port, and the data received by all switches is forwarded to this monitoring port, which provides the received data; but these data do not have a common time reference. In addition, only valid data can be forwarded to the data port, which makes error analysis difficult. [0003] In addition, for cost reasons, there is no additional monitoring port reserved on the productized switch, and only one additional switch can be inserted into the existing network connection. The insertion of this s...
