Description

Vehicle The present invention is a technology related to a vehicle capable of smoothly performing data transmission and reception between multiple hosts. Electronic modules installed in a vehicle exchange information with each other through a network, thereby performing a wider variety of functions. In other words, vehicle electronic modules perform various functions by exchanging data with each other via the CAN data bus, Ethernet, UART (Universal asynchronous receiver/transmitter), and SPI. In particular, in the case of vehicles, the CAN (Controller Area Network) data bus used in the vehicle network refers to a network system used for data transmission and control between the vehicle's electronic modules. However, as the number of electronic components in the vehicle increases, the communication load rises and CAN communication signals are delayed, leading to a problem where vehicle control performance deteriorates. However, with recent controllers trending toward more diverse external communication channels and increasing data volumes, gateway software needs to transmit data at short intervals to send all data. Such short-period data transmission can lead to the problem of increased system load on both the secure host and the receiving host to handle data transmission and reception.
