Intelligent gateway device for vehicle controller LAN

Abstract

The intelligent gateway device for vehicle controller LAN includes LAN bus interface, Ethernet interface, radio network interface, data back-up module, intelligent microcontroller, bus, other bus interface, vehicle control unit, phonetic and display interface and real-time data analyzing module. The device realizes the conversion between modularized LAN protocol and other network protocols, WWW web page browsing, display, phonetic prompt, etc; has running data analysis, record, control and other vehicular computer functions; and may be used widely in running state monitoring, data record, fault treatment, etc. of vehicle with LAN interface.

Description

technical field [0001] The invention relates to the field of automobile automation. technical background [0002] Car bus technology is used in today's mid-to-high-end cars. The automobile bus provides a unified data exchange channel for various complex electronic devices, controllers, measuring instruments, etc. inside the automobile. Some auto experts believe that just like the introduction of integrated circuits in the 1970s and microprocessors in the 1980s, the introduction of data bus technology in the past 10 years will also be a milestone in the development of automotive electronics technology. [0003] Since the 1990s, the number of components commanded by the electronic control unit (ECU) on the car has increased, such as electronic fuel injection devices, anti-lock braking devices, airbag devices, electronically controlled door and window devices, active suspension, etc. Wait. With the widespread application of integrated circuits and single-chip microcomputers ...

AI Technical Summary

Problems solved by technology

Due to the lack of relevant testing and maintenance equipment, once the engine fails, our maintenance personnel can only drill holes in the engine and put the sensor directly into the engine for detection. The operation is cumbersome and the equipment is complicated, and it is not conducive to protecting the engine as a whole. structure

[0010] As another example, although some of the existing automobile instruments use the bus communication method, the bus is a dedicated design. Due to the non-uniform hardware standards and incompatible communication protocols, the instruments produced for Company A’s vehicles cannot be used on the vehicles of Company B at all. Use, even less likely to be used in new automotive systems with CAN interface, poor versatility

[0011] For another example, the unreasonable operation of the driver or the operation in violation of traffic rules is closely related to the maintenance of the car and the safety of driving. Form a mechanism for electronic reporting, which will be beneficial to car maintenance and safe driving

For example, in a manual transmission car, the driver's shifting is based on experience, and it is easy to happen that the high gear should be increased but not increased, that is, low gear and high speed driving, which is not conducive to reducing fuel consumption, and is likely to cause wear and tear on the parts of the car.
