TiEV: The Tongji Intelligent Electric Vehicle in the Intelligent Vehicle Future Challenge of China
TiEV is an autonomous driving platform implemented by Tongji University of
China. The vehicle is drive-by-wire and is fully powered by electricity. We
devised the software system of TiEV from scratch, which is capable of driving
the vehicle autonomously in urban paths as well as on fast express roads. We
describe our whole system, especially novel modules of probabilistic perception
fusion, incremental mapping, the 1st and the 2nd planning and the overall
safety concern. TiEV finished 2016 and 2017 Intelligent Vehicle Future
Challenge of China held at Changshu. We show our experiences on the development
of autonomous vehicles and future trends
A mosaic of eyes
Autonomous navigation is a traditional research topic in intelligent robotics and vehicles, which requires a robot to perceive its environment through onboard sensors such as cameras or laser scanners, to enable it to drive to its goal. Most research to date has focused on the development of a large and smart brain to gain autonomous capability for robots. There are three fundamental questions to be answered by an autonomous mobile robot: 1) Where am I going? 2) Where am I? and 3) How do I get there? To answer these basic questions, a robot requires a massive spatial memory and considerable computational resources to accomplish perception, localization, path planning, and control. It is not yet possible to deliver the centralized intelligence required for our real-life applications, such as autonomous ground vehicles and wheelchairs in care centers. In fact, most autonomous robots try to mimic how humans navigate, interpreting images taken by cameras and then taking decisions accordingly. They may encounter the following difficulties
Autonomous Driving Platform Performance Analysis
Through data analysis of various plots and figures it will be possible to determine the best control parameters to get the best performance out of the autonomous driving platform. This data, presented in this thesis, will show quantitatively what the best control strategies are through comparison of different versions of the platform
What impressions do users have after a ride in an automated shuttle? An interview study
In the future, automated shuttles may provide on-demand transport and serve as feeders to public transport systems. However, automated shuttles will only become widely used if they are accepted by the public. This paper presents results of an interview study with 30 users of an automated shuttle on the EUREF (Europäisches Energieforum) campus in Berlin-Schöneberg to obtain in-depth understanding of the acceptance of automated shuttles as feeders to public transport systems. From the interviews, we identified 340 quotes, which were classified into six categories: (1) expectations about the capabilities of the automated shuttle (10% of quotes), (2) evaluation of the shuttle performance (10%), (3) service quality (34%), (4) risk and benefit perception (15%), (5) travel purpose (25%), and (6) trust (6%). The quotes indicated that respondents had idealized expectations about the technological capabilities of the automated shuttle, which may have been fostered by the media. Respondents were positive about the idea of using automated shuttles as feeders to public transport systems but did not believe that the shuttle will allow them to engage in cognitively demanding activities such as working. Furthermore, 20% of respondents indicated to prefer supervision of shuttles via an external control room or steward on board over unsupervised automation. In conclusion, even though the current automated shuttle did not live up to the respondents’ expectations, respondents still perceived automated shuttles as a viable option for feeders to public transport systems.Green Open Access added to TU Delft Institutional Repository ‘You share, we take care!’ – Taverne project https://www.openaccess.nl/en/you-share-we-take-care Otherwise as indicated in the copyright section: the publisher is the copyright holder of this work and the author uses the Dutch legislation to make this work public.Transport and PlanningHuman-Robot InteractionIntelligent VehiclesTransport and Plannin
Hypersonic Research Vehicle (HRV) real-time flight test support feasibility and requirements study. Part 2: Remote computation support for flight systems functions
The requirements are assessed for the use of remote computation to support HRV flight testing. First, remote computational requirements were developed to support functions that will eventually be performed onboard operational vehicles of this type. These functions which either cannot be performed onboard in the time frame of initial HRV flight test programs because the technology of airborne computers will not be sufficiently advanced to support the computational loads required, or it is not desirable to perform the functions onboard in the flight test program for other reasons. Second, remote computational support either required or highly desirable to conduct flight testing itself was addressed. The use is proposed of an Automated Flight Management System which is described in conceptual detail. Third, autonomous operations is discussed and finally, unmanned operations
I Am The Passenger: How Visual Motion Cues Can Influence Sickness For In-Car VR
This paper explores the use of VR Head Mounted Displays
(HMDs) in-car and in-motion for the first time. Immersive
HMDs are becoming everyday consumer items and, as they
offer new possibilities for entertainment and productivity, people
will want to use them during travel in, for example, autonomous
cars. However, their use is confounded by motion
sickness caused in-part by the restricted visual perception
of motion conflicting with physically perceived vehicle motion
(accelerations/rotations detected by the vestibular system).
Whilst VR HMDs restrict visual perception of motion, they
could also render it virtually, potentially alleviating sensory
conflict. To study this problem, we conducted the first on-road
and in motion study to systematically investigate the effects
of various visual presentations of the real-world motion of
a car on the sickness and immersion of VR HMD wearing
passengers. We established new baselines for VR in-car motion
sickness, and found that there is no one best presentation
with respect to balancing sickness and immersion. Instead,
user preferences suggest different solutions are required for
differently susceptible users to provide usable VR in-car. This
work provides formative insights for VR designers and an entry
point for further research into enabling use of VR HMDs,
and the rich experiences they offer, when travelling
Vehicle Interior Access Deployable Worksurface Mechanism Concept Product Design

Under the Supervision of Professor Mohammad Habibur Rahman
Easy access and adjusting the vehicle interior configuration to a variety of situations and uses is the general desire for any vehicle user. To meet such desire an attempt has been made in this study to conceptualize a design to develop a new mechatronic product called re-configurable vehicle interior console mechanism to deploy a worksurface (DWS), which will provide flexible use of the vehicle’s interior of both partial and fully autonomous vehicles. This re-configurable vehicle interior console will deploy the DWS using a power sliding mechanism concept enabled by electrical and electronic control unit circuits. This DWS will have 2 degrees of freedom (DOF) in its operation. Each user can access a DWS by pressing the nearby button. The console will move towards the center of the leg space and the electrical motor actuator and lead screw inside the console will drive the DWS by sliding it up and the DWS will down fold over the lap level of the user to offer a convenient individual worksurface. The inner side of the console body is designed to accommodate four DWS units, two each on its right and left sides, to cater to four users in a vehicle. The DWS power sliding mechanism concept product design will address the problems faced by the extreme users in the carpooling group of office goers, business travellers, family and friends going on a long road travel vacation trips. This DWS mechanism product’s performance and size can be customized, re-designed and modified to assemble inside the console body for the user’s accessibility, personalized and sharing experience in vehicle interiors of SUV, minivan and autonomous vehicles as well.
