On-vehicle gateway device, method for controlling an on-vehicle gateway device, connection device and connection control method
First Claim
1. A connection device for connecting to a network of a control system and an external device of the network, comprising:
- a memory circuit to store data transmitted from the external device to the control system and a control circuit,wherein the control circuit is configured to;
determine whether or not the control system is stable,when the control system is determined to be stable, determine whether or not to transmit the data based on a number of transmissions of the data or a validity duration of the data or a priority level of the data stored in the memory circuit, andwhen the control system is determined to be stable and the data is determined to be transmitted, transmit the data stored in the memory circuit to the control system.
