At present, Intelligent and Connected Vehicle (ICV) has become the strategic direction of the development of China’s automobile industry. The development of ICVs can provide new momentum and the best carrier for the innovation and development of Artificial Intelligence (AI). At the same time, AI innovation and development can also drive the development of ICV industry. Through deep excavation, analysis of AI and ICV technology literatures, based on AI driven ICV development status, from the AI innovation driven ICV industry development path, this paper proposes to build 4 system platforms for ICVs based on AI and vigorously erect development paths for CPU of ICVs and key components for ICVs. Aim of the research is to promote the development of ICV industry well, so as to effectively solve the issues of traffic accidents, urban road congestion, fossil energy consumption and air pollution faced by human society, and realize the transformation and upgrading of the automobile industry and the establish a new ecology of ICV industry.

Lithium-ion batteries with silicon-based anodes are considered to be the most promising next-generation Lithium-ion batteries due to their high theoretical specific capacity and low operating voltage. However, the inherent huge volume expansion of silicon-based materials after lithiation and the resulting problems seriously restrict the practical application of silicon-based anodes. From different functional types of polymer binders, the latest research progress of binders for silicon-based anodes is summarized. Finally, a method for rationally designing binders for silicon-based anodes and suggestions for industrial production are proposed.

With the vigorous development of the automobile industry, the environmental pollution problem of internal combustion engine vehicles has become prominent day by day, especially the front-rear drive vehicles with large displacement engines. Influenced by increasingly stringent fuel consumption and emission regulations, influential automobile enterprisesat home and abroad have turned to the hybrid technology for front-reardrive vehicles. Through the investigation and research on the existing energy-saving technologies of hybrid electric vehicles, this paper summarized the typical front-rear drive hybrid electric vehicles and technological solutions, analyzed the powertrain architecture principle, key assembly parameters, advantages and disadvantages of hybrid technologies as well as the future development trends and challenges.Promoting technological level and development are major trends for front-rear drive hybrid electric vehicles.

The European Union issued COMMISSION REGULATION (EU) 2018/1832, which requires vehicles to be equipped with devices, i.e. On-Board Fuel and/or Energy Consumption Monitoring （OBFCM）devices, which can measure fuel consumption in real time, requires the accuracy of the collected data and requires that the fuel consumption data stream should meet the current vehicle-machine communication standards. In this paper, the feasibility of vehicle terminal coverage of OBFCM is studied by comparing and analyzing the OBFCM device and the policy, function and technology of vehicle fuel consumption monitoring in real time. The results show that the vehicle terminal coverage OBFCM device can be applied in all aspects above, and has great development prospects. China should carry out the collection of driving data for fuel consum-ption as soon as possible and establish relevant industry standards.

With the improvement of electric vehicle technologies, integrated design has gradually become the direction of development. This paper mainly elaborates the structural integrated design of the electric vehicle system: six-in-one integrated design of PDU, OBC, DC/DC, BDU, BMS and battery, two-in-one integrated design of AC charging cradle and DC charging cradle, and integrated design of high voltage harness connected to compressor and high voltage harness connected to PTC. Compared with the distributed design, it can make full use of the vehicle space, short harness length and reduce the number of components, and then reduce the weight and cost.

Engine misfire is a major problem affecting the high quality of the vehicle, and misfire problem of heavy natural gas vehicle for China VI is a difficult problem in the industry. In this paper, the actual misfire problem of a heavy-duty natural gas vehicle is studied. Based on the field of vehicle calibration, the causes of misfire in hardware and software are analyzed, and the calibration improvement scheme related to Exhaust Gas Recirculation (EGR) and excess air ratio(λ) module is studied in depth. The scheme combination aims to solve typical vehicle misfire problems in plateau, high cold, high temperature and mountainous areas, and has good application effect on this model, providing a new calibration perspective and ideas for solving misfire of heavy duty natural gas vehicle.

This paper analyzes the control strategies of dynamic system operation mode of hybrid electric vehicle. Based on factors such as vehicle torque demand, battery SOC, accelerator pedal and brake pedal, the switching conditions, control methods and assembly states between different modes are analyzed. The operation modes of the vehicle include pure electric start mode, 4WD start mode, engine start mode, idle charge mode, series drive mode, drive charge mode, parallel drive mode and energy recovery mode. The analysis of control strategies for these operation modes can be used to provide references for relevant engineering developers.

According to the performance requirements of the thermal management system for the fuel cell engine, the thermal management system of a fuel cell engine is taken as the research object, combined with the selection scheme of parts and pipeline design, the fluid model of the thermal management system is established, including the water pump, the thermostat, the radiator, the PTC and pipelines. At the same time, the flow resistance characteristics of the components are analyzed, and the heat transfer coefficient of the radiator is calculated. Finally, the influence of the components on the flow resistance and temperature of the thermal management system is studied by fluid simulation in the situation of large cycle and small cycle. The calculation and analysis can provide guidance and basis for the design of the thermal management system of the fuel cell engine.

In the in-vehicle simplified Chinese display standards, 3 safety related questions need to be explored and established: (1)The minimum character’s height that drivers can read on in-vehicle screens; (2)The maximum number of characters that drivers can accept in a single information prompt; (3)The total number of characters that drivers can read when completing one non-driving task. Based on 3 types of experiments on a test bench through a 128-person within-subject design, results suggest: (1)The automobile cockpits information display should use a minimum simplified Chinese character font height no less than 16’ arc minutes; (2)A single message prompt in automobile cockpits contain no more than 12 characters; (3)The total characters for messages in a single non-driving task no more than 30 characters.
