Achievements In 1993, Saab JAS39 battleplane was crashed in a performance of Water Festival, Stockholm. The reason of this accident was investigated that the aircraft interaction system led the pilot’s misjudgment and thus curried out the incorrect operation. Subsequently, she took the project leader for two research projects concerning human-computer-interaction: human factors in 3D audio presentation and human factors in speech technology application. The research directly upgraded the auditory interaction system in the next generation of JAS39. Research results also have led to new projects to integrate multi-modal applications in complex control systems. From 2006, she has been trying to introduced vehicle interaction design to China. Since 2013, she has been working together with Chinese partners including Tsinghua University to organize conference on HMI every year in order to promote the development of vehicle HMI design, especially in Chinese vehicle market. |

Analysis of Typical Automakers’ Strategies for Meeting the Dual-Credit Regulations Regarding CAFC and NEVs Yue Wang, Fuquan Zhao, Yinshuo Yuan, Han Hao, Zongwei Liu |
||
| The parallel corporate average fuel consumption (CAFC) and new energy vehicle (NEV) credit schemes that have been introduced by the Ministry of Industry and Information Technology of China is an innovative attempt to simultaneously regulate conventional gasoline vehicles (CGVs) and NEVs in the passenger vehicle sector that is expected to function as a long-term management mechanism for CGVs to be more energy-efficient and NEVs to be well-promoted. This will have a significant impact on trends in China’s automotive industry and automakers’ business decisions. Taking the cases of four typical automakers with different levels of average fuel economy in their CGVs and advanced NEV production, scenario analysis has been applied to generate these automakers’ alternatives in relation to compliance with the dual-credit regulations in force from 2017 to 2020 based on the Interim Measures on the Joint Management of CAFC and NEV Credits (Draft). These automakers’ alternative approaches to compliance are compared. Further, in view of the financial losses as a result of halted production if they fail to comply, the values of CAFC and NEV credits and corresponding influencing factors are analyzed from the automakers’ perspective. Finally, the most cost-effective compliance strategies for these automakers are summarized and suggested improvements in the regulations are proposed for the government. | |||

Blind Spot Obstacle Detection from Monocular Camera Images with Depth Cues Extracted by CNN Yuxiang Guo, Itsuo Kumazawa, Chuyo Kaku |
||
| The images from a monocular camera can be processed to detect depth information regarding to obstacles in the blind spot area captured by the side-view camera of a vehicle. The depth information is given as a classification result “near” or “far” when two blocks in the image are compared with respect to their distances and the depth information can be used for the purpose of blind spot area detection. In this paper, the proposed depth information is inferred from a combination of blur cues and texture cues. The depth information is estimated by comparing the features of two image blocks selected within a single image. A preliminary experiment demonstrates that a convolutional neural network (CNN) model trained by deep learning with a set of relatively ideal images achieves good accuracy. The same CNN model is applied to distinguish near and far obstacles according to a specified threshold in the vehicle blind spot area, and the promising results are obtained. The proposed method uses a standard blind spot camera and can improve safety without other additional sensing devices. Thus, the proposed approach has the potential to be applied in vehicular applications for the detection of objects in the driver’s blind spot. | |||

Highly Fuel-Efficient Transmission and Propulsion Concepts Ferit Küçükay, Andreas Lange, Lin Li |
||
| The integration of one or more electric machines into the drivetrain has resulted in many different powertrain concepts in recent years, ranging from the P2 hybrid to dedicated hybrid transmission (DHT). Two types of DHT with different characteristics are investigated. The first type is the power split hybrid (PS-DHT), which has very low mechanical complexity but needs high electrical effort in the transmission. The second type is multi-mode DHT (MM-DHT), which has a slightly higher mechanical complexity but much less electrical effort when compared with the PS-DHT. A transmission synthesis is used to determine the concept of the MM-DHT. The three different powertrain concepts (i.e., P2, PS-DHT, and MM-DHT) are analyzed and evaluated regarding fuel economy and performance. Legal driving cycles (e.g., Worldwide Harmonized Light Vehicles Test Procedure) and the 3D method (driver, driven vehicle, driving environs) are used to investigate the drivetrain in the context of real driving operation. Results show that the two DHT concepts offer better fuel economy than the P2 hybrid drivetrain while still providing the same or even better driving performance. The study also shows that new hybrid concepts created with transmission synthesis can lead to further improvements in hybrid powertrains. | |||

Cost-efficient Thermal Management for a 48V Li-ion Battery in a Mild Hybrid Electric Vehicle Chao Yu, Guangji Ji, Chao Zhang, John Abbott, Mingshen Xu, Pieter Ramaekers, Jianxiang Lu |
||
| The 48V mild hybrid system is a cost-efficient solution for original equipment manufacturers to meet increasingly stringent fuel consumption requirements. However, hybrid functions such as auto stop/start and brake regeneration are unavailable when a 48V battery is at very low temperature because of its limited charge and discharge capability. Therefore, it is important to develop cost-efficient thermal management to warm up the battery of a 48V mild hybrid electric vehicle (HEV) to recover hybrid functions quickly in cold climate. Following the model-based “V” process, we first define the requirements and then design different mechanisms to heat a 48V battery. Afterwards, we build a 48V battery model in LMS AMESim and conduct co-simulation with simplified battery management system and hybrid control unit algorithms in Matlab Simulink for analysis. Finally, we carry out a series of vehicle experiments at low temperature and observe the effect of heating to validate the design. Both simulation results and experimental data show that a cold 48V battery placed in a cabin with hot air can be heated effectively in the developed “Enhanced Generator Mode with 48V Battery” mode. The entire design is in a newly developed software that cyclically charges and discharges a 48V battery for quick warm-up in cold temperature without needing any additional hardware such as a heater, making it a cost-efficient solution for HEVs. | |||
