Abstract:
In our modern daily life, automobile vehicles are the most common transportation tools, however, collisions cause millions of people injury or death and billions of dollar property damage every year, safety is the top concern in automobile industry and researchers, great resources and efforts are focused on preventing collisions, but not much on reducing the severity of the collisions when they really happen. A new collision safer device is proposed to substantially reduce the impact force on the people and on the vehicles during the collision, lives can be saved and property damage can be reduced. The proposed collision safer device has one free rotation wheel installed horizontally at the vehicle lower front left and right corners, respectively, it can be also installed in the middle section of the bumper location as option; the wheels will be first contact of the vehicle when in collision; when the collision is non-perpendicular, the collision force component parallel to the collision surface of the collision will cause the wheel rotating and make the vehicle rolling slide along the direction of the parallel force component, therefore, the collision will be softer and less harmful, so lives could be saved and property damage could be reduced. At 45 degree collision angle, the effective impact force on the people and the vehicle can be reduced about 30%, such 30% impact force difference could mean life or death; at 30 degree collision angle, the effective impact force is half of the original impact force; and at 20 degree collision angle, the effective impact force is about one third of the original impact force, such dramatic reduction of the effective impact force will significantly reduce the severity of the collision, and reduce the collision injures and property damages. Millions of lives and billions of dollars for the property damages will be saved in the future if the proposed collision safer devices are installed on all vehicles in the future. This collision safer device is simple, low cost and can be installed on all types of vehicles. The proposed collision safer devices can be perfectly fit into the structure of the crumple zone of the vehicles and provide maximum protection for the occupants of the vehicles. The function of the proposed collision safer devices in most frequently happened collision situations are discussed.

Abstract:
Automated vehicles are expected to be the sustainable future for safe driving, efficient traffic, and reduced energy consumption. Almost every challenge concerning modern road traffic such as traffic jam, road fatalities, carbon emissions, and parking space can be solved by smart mobility system such as automated vehicle-based car sharing. Most of major automakers have already commercialized various advanced driving assistance systems (ADAS) to enhance driving safety and to reduce driving workload, and are planning to commercialize Level 3~4 automated vehicles for personal mobility from the year of 2020. As of 2018, automated vehicle-based smart mobility systems are operated in several sites and it is expected that smart mobility services with large fleets of automated vehicles will be available in 100 cities in the year 2025. Although still there exist many technical challenges concerning full automated driving in urban environments, there has been rapid progress in the field of automated vehicles. In this talk, technical issues and recent developments for automated driving in urban environments will be presented. A hierarchical structure for decision and motion planning for autonomous driving at unsignalized intersection has been developed. Based on real road driving data analysis an intelligent driver-veicle models for cross-first or yield has been developed. Index variables for target intension inference at intersection have been defined and interacting multiple model (IMM) based intention inference scheme has been developed. A target inrention inference-based decision and motion planning has been investigated via computer simulation and successfully implemented on an automated driving vehicles.

Abstract:
Automated driving functions are able to increase vehicle safety and customer comfort. They also have potential to improve road traffic management and to reduce negative impacts of traffic on environment. In this way, car manufacturers, supplier and reserach institutes increasingly perform R&D activities in the area of automated driving on the way to the self-driving car. The submitted work treats an evaluation of automated driving functions for the application in electrically driven low-cost city cars. The intended evaluation is focused on SAE level 5, which means fully automated cars that do not require a driver, and even no passengers. This type of vehicles might be used for logistics, delivery service and similar applications, but also as self-driving people mover. Autonomous navigation of such vehicles is similar of those of robots, which includes tasks of localization, path planning, and path execution. These tasks require appropriate sensor systems and computation strategies to recognize and cluster continuously changing environmental conditions in daily traffic scenarios. An important role plays the applied sensor and object recognition technology, representing cost-intensive modules. In this context, different sensor technologies are evaluated in terms of their capability of road and surounding area observation, driveway and obstacle recognition, the robust provision of data for vehicle control and path planning as well as economic parameters. Sensor fusion comes to use to combine advantages of different technologies and to provide reliable object detection to under different environmental conditions. The paper closes with exemplary applications of autonomous driving technologies in small city vehicles and a prospect of development trends.

Abstract:
Engineering criteria and guidelines have been developed and consolidated over the years to develop a good car according to the target market and customer requirements. These receipts worked well with reasonably stable boundary conditions, linear forecast on requirement and customers’ expectations. Moving to the future, looking into the electrification, increased on-board electronics, autonomous driving and connectivity, there will be somehow impact on users’ perception and expectation.
While the whole future of mobility is clearly shifting, the need of a fundamental excellence in the dynamic experience is unchanged. There will always have the need for cabin comfort; quietness, temperature control, smooth ride, convenience and safety feeling. All at minimum energy cost. The expectation is indeed increasing.
The proposal of this presentation is to discuss the successful vehicle development under the perspective of new energy vehicles. It’s about the challenges on application of lightweight strategies, the increased demand on thermal integration, specific componentns and software integration. It will also be presented the methodologies, test and simulations available to support a good architecture and conscious balance of vehicle attributes. It’s about setting cross-attributes balancing as an early development strategy as opposed to a late trade-off decision.

Abstract:
Steam ejector refrigeration systems are promising for energy efficiency. The aim of this paper is to design exhaust gas heat-driven ejector cooling system in an automobile. The system uses water as the working fluid. The water will be boiled in waste heat boiler by exhaust gas heat and sent to steam ejector utilized instead of compressor in conventional refrigeration systems. At various speed of an automobile, COP (Coefficient of Performance) and cooling capacity is investigated. Therefore, Cooling is provided in evaporator, although COP is quite low in ejector refrigation cooling system, the fuel consumption and green house gas emissions is reduced in the ejector refrigeration system. In addition to energy efficiency, since this refrigeration system has any compressor, it operates under low sound levels and provides less maintenance.

Abstract:
The restraint sysetm design for occupant protection becomes a new challenge for a laterally facing seated occupant in an automated driving minivan. This study is to evaluate effectiveness of various new restraint system concepts for occupant protection in frontal, side and rear crash seconarios. The case occupant is a mid-sized male represented by GHBMC M50-OS v1.8.4 human model, positioned in a laterally facing seat in middle of the vehicle. The evaluated restraint concepts include 3-pt seatbelt with dual load-limiter retractor and pretensioners, 4-pt seatbelt, torso restrain airbag (seatbelt integrated), seat-mounted far-side airbag, customized head airbag and floor airbag. Multiple loading cases are created for different crash cenarios including the US frontal and oblique NCAP tests, pole and MDB (Moving Deformable Barrier) for near and far side, and rear impact. Effectiveness of each restraint system configuartion with the new concepts is evaluated for the loading cases respectively. For each case the occupant kinematics is analyzed and the occupant injury measures (OIMs) are obtained. Preliminary optimization of the restraint combinations and design parameters are also performed to mitigate the OIMs. The results indicate that a combination of the 3-pt seatbelt and the other new concepts significantly reduce the OIMs over the baseline (the 3-pt seatbelt alone). The torso restrain airbag, seat-mounted far-side airbag, and special head airbag show good benefits.

Title: Modal finite element analysis of the first global body in white Saudi car Gazal 1
Biography:
Ahmad Gemeal pursued his PhD from Al Faraby University Kazakhstan National University, Kazakhstan. He worked on the project Gazal1 (Saudi Car) at the Advanced Manufacturing Institute of King Saud University, KSA. He is currently working in the Department, Plastic Deformation Lab at the Central Metallurgical Research and Development Institute Metals Technology, Egypt. He has published more than 16 papers in reputed journals.
Abstract:
Modal analysis test the for first Saudi car Gazal1 was carried out. The chassis-alone modal analysis was made and its result for first torsional mode is 34.9 Hz (the target is >26 Hz) and for first bending mode is 38.2 Hz (the target is >26 Hz). Those results are in target. In general the chassis has a global good behaviour with high values of Eigen modes. The strain energy distribution is well distributed in the structure that will support the BIW (Body in white) upper structure. This is a good base for the complete global BIW (BIW+chassis) possible behaviour. Global BIW modal analysis was also made. The result for the first bending mode is 30.7 Hz which is in target (the target is >29 Hz). But the analysis does not reach the target for the first torsional mode 17.6 Hz (the target is >26 Hz), due to the weakness of the rear end area which consists of upper joint and lower joint. This analysis showed that the connection between the D pillar and the rear longitudinal member is weak and that the main problem is located in lower joint area. Hence, the connection with the rear panel has to be improved. An upper joint and lower joint sensitivity analysis was also made to understand which joint that has the highest influence on the body normal modes and, hence, to identify the areas where the design change activities should be focused. The sensitivity analysis shows that upper joint has the highest sensitivity for first torsional mode, while lower joint has the highest sensitivity for first bending mode. Knowing that, it is the first torsional mode that is out of target, then, the design change activities must be focused on the strengthening of upper joint.

Abstract:
Germany belongs to the countries that benefitted extraordinarily from the worldwide automotive boom, with a significant percentage of the population employed directly at one of the makers or within the related network of suppliers. Previously vehicle sales were not only fueled by the obvious convenience factor but also cars as status symbols, affordable cost of ownership - as long as environmental costs were of lesser concern – and governments eager to help build lasting industries. Today the landscape has changed in more ways than can be considered healthy for any sector and it appears as though all changes occur simultaneously. In a more and more urbanized and space constricted environment, traveling by car – at least at day light – has certainly become less fast and less cheap, nor does it continue to add much to one’s status. On top of all these, societies are becoming increasingly aware of the implications for health and climate. Nevertheless, moving remains a necessity. The neglect of countryside infrastructure and subsequently sprawling cities alone pose increasing challenges – to an increasing number of stakeholders. Now it is not just about makers, drivers, road building respectively maintenance, oil companies and car dealers. Emerging technologies further involve utilities, mobility providers and platforms which here – as elsewhere – facilitate transactions and re-shape markets. Also in order to prevail, established players, we take a fresh look at value chains and this is where opportunities arise. Highly capitalized buyers contribute to drive - as much as control - innovation, with smaller companies looking for Exit Partners. The presentation looks at various transactions in the automotive space as well as their motives.
