Embodiment Construction

[0026] The present invention provides a smart car with an Ethernet gateway with a post-configuration function, which includes: an Ethernet gateway with 6 CAN bus interfaces, 4 Ethernet interfaces and an integrated TBOX, wherein: the Ethernet gateway includes: Power module interface, IO module interface, RF front-end, MCU, ARM7 Cortex, CAN module interface, Ethemet 100BaseTX, Ethemet Switch100BaseT1; the Ethernet gateway has a post-configuration function, and the gateway routing software is configured under the condition that the hardware remains unchanged. Hierarchical design; when the signal requirements change, import the requirement change table through the configuration software and generate a HEX file, and download the configuration information to the gateway software to quickly respond to changes in requirements and avoid repeated development and verification of software.

[0027] As a further improvement, the gateway routing software is divided into CAN message whole fra...

Abstract

The invention discloses a smart car provided with an Ethernet gateway with a back configuration function. The smart car comprises six CAN bus interfaces, four Ethernet interfaces and the Ethernet gateway with an integrated TBOX, the Ethernet gateway comprises a power supply module interface, an IO module interface, an RF front end, a MCU, an ARM7 Cortex, a CAN module interface, an Ethemet 100 BaseTX and an Ethemet Switch 100BaseT1; the Ethernet gateway has the back configuration function, and under the circumstance of ensuring that hardware is the same, gateway routing software is subjected tohierarchical design; when the signal requirements are changed, a requirement changing list is imported to generate an HEX file through configuration software, configuration information is downloadedto the gateway software to quickly respond to changes of the requirements, and it is avoided that software needs to be repeatedly developed and verified.

Description

technical field [0001] The present invention relates to a smart car with an Ethernet gateway with a post-configuration function. Background technique [0002] With the integration of autonomous driving, Internet of Vehicles, big data, cloud computing, artificial intelligence and other fields of technology, vehicle interaction becomes more complex. The number and complexity of on-board electronic devices in smart cars has increased significantly, and the demand for low-cost, high-bandwidth networking solutions is also on the rise. More and more sensors, controllers, and interfaces have higher and higher bandwidth requirements, and the demand for communication between different computing units and different domains in the vehicle is getting stronger and stronger. [0003] Traditional automotive network communication is mainly based on CAN and LIN. The high-end architecture is based on independent gateways, and the network segments are divided according to functional domains, ...
