Semi intelligent vehicle chassis and body technology

the electronization, intellectualization and networking of vehicles are important signs of the development of modern vehicle chassis and body technology. With the increasing requirements of consumers for automotive functions and performance, the electronic system has accounted for 30% of the total cost in an ordinary car, and the proportion is higher in a high-end car. At present, automotive electronic technology is in the third stage. L6 bit or 32-bit microprocessors are widely used in control chips, and the control technology is developing in the direction of intelligence and networking. At this stage, many new research hotspots and fields have emerged. Briefly described as follows:

1 automotive bus technology

at present, after 20 years of development, can bus (controller area network) has occupied 85% of the market share in automotive powertrain called J. Its upgraded version is TTCAN (time triggered can)

because the price of LIN bus (local interconnect network) is low, and MCU can be embedded into body parts called J, which makes it become smart parts with networking function, so as to further reduce harness and cost

the sheet metal sample can be clamped in a wedge-shaped way. The European automobile manufacturers led by BMW have formulated the interconnection standard most (media OrientedSystems transport) between in car media to realize the information sharing between in car CD, GPS, t and other media devices

flexray is regarded as the next generation of automotive network protocol. It has sufficient bandwidth, high reliability, and strong response ability to make the operation more stable in real time. It can realize X-by-wire technology, such as applied in steering, braking, auxiliary staff protection system (SRS) and vehicle stability control system. More and more automobile manufacturers begin to adopt this standard

2 new chassis technology

the new technologies adopted by the automobile chassis mainly include friction and wear testing machines, excluding: the automobile cruise control system CCS, the picked green vegetables with gray oil stains on the surface, the automobile electronic control braking system EBS, the automatic parking system, the double clutch automatic speed converter DCT, the electronic stability system ESP, the wire control technology DBW, the chassis integrated control system UCC, etc

3 new body technology

the new technologies adopted by the car body mainly include: car navigation system GPS, occupant perception system OPDS, 42V power supply system, mobile multimedia, human vehicle communication system, road offset warning system, night vision system, intelligent front light follow-up system AFS, etc

4 car service technology

car service collects and shares information about cars through 3G mobile Internet. Through information processing, it realizes the communication between cars and roads, cars and owners, car owners and owners, car owners and third-party service providers, and makes car life more intelligent

car coupling system is a network and application that comprehensively utilizes advanced sensing technology, computing technology, intelligent technology, network technology and control technology to realize the full-scale perception of roads and traffic, realize the real-time interaction of human range and human capacity data among multiple systems, carry out the whole process traffic control of each vehicle, and carry out the full time and space control of each road traffic, with the main goal of improving traffic efficiency and traffic safety
