Vision based solution for auto- maneuvering of vehicle for emerging market: Author/Co-Author: Singh Ashwani, SDV Ram Kumar, Bose Souvik, Lalwani Chandraprakash General Motors Technical Centre India Key words: Image Processing, Gap finding, virtual/Imaginary lines, Advance Driver Assist System (ADAS), Vehicle to vehicle(V2V)/Vehicle to Infrastructure(V2I/V2X) Research & Engineering Objective: For the various levels of autonomous, the current perception algorithms involve considerable number of sensor inputs like cameras, radars and Lidars and their fusion logics. The planning route for the vehicle navigation is done through map information which is highly volatile and keep changing many at times. Existing steering assist feature during a curve is available by combining additional driver monitoring camera & 360 degree camera. The complexity is very high in the implementation and computation of these algorithm. These solutions are not cost-effective for emerging markets. Non-availability of required infrastructure in developing countries is one of the additional constrain. Feature unavailability due to road infrastructure (ex: poor or no lane markings), bad weather will lead to higher customer dissatisfaction. The objective is to develop a logic/study…
 

An ADAS Feature Rating System: Proposing a New Industry Standard

To be published on 2019-10-07 by SAE International in United States
The rapid introduction of Advanced Driver-Assistance Systems (ADAS) in modern vehicles has the commendable overarching goal of improving the Safety of the driver, passengers and other traffic participants. As integral part of Automated Vehicles included within the SAE Levels 1-3, ADAS prepare the path toward full autonomy and consequently they are subjected to some of the same challenges. A recent SAE EDGE™ report considers the following four areas to be unsettled domains in automated vehicle sensors, due mainly to the lack of common understanding around various aspects pertaining to each of them: • Terminology and taxonomy • Testing, simulation, and calibration • Security, robustness, and integrity • Data ownership and privacy Velodyne LiDAR, Inc. is the lead company in automotive Lidar sensing technology, but also one of the strongest Safety Advocacy voices within the industry. Accordingly, Velodyne published several thought leading white papers addressing the first three topics listed above. This new SAE paper by Velodyne will build on the previous framework related to developing, testing, validating and marketing Lidar centric Safety oriented ADAS solutions.…
 

Braking Requirements for Optimizing Autonomous Emergency Braking Performance

To be published on 2019-09-15 by SAE International in United States
The continuous improvement on vehicle technology has successfully helped to decrease general road fatalities figures in the last years. Vehicle technology new developments have contributed to improve vehicle structural performance and therefore passive protection, but also the inclusion of electronic control units has provided new opportunities to expand active safety systems. This is the case for systems like anti-lock braking systems (ABS), electronic stability control (ESC) and brake assist (BA) among many others. A more advanced generation of active systems includes sensorial units that monitor vehicle’s surrounding and detect potential hazards, such as an imminent collision, and performs an automatically and commanded emergency braking to lessen or mitigate the consequences of the impending accident. For this latest system, the so-called autonomous emergency braking (AEB), various consumer testing protocols, such as NHTSA and NCAP protocols, propose and periodically update test catalogues in order to evaluate the performance of such systems and later to inform potential consumers. This study aims to determine what basic braking system requirements and its target setting shall be demanded on the definition…
 

Downhill Safety Assistant Driving System for Battery Electric Vehicles on Mountain Roads

When driving in mountainous areas, vehicles often encounter downhill conditions. To ensure safe driving, it is necessary to control the speed of vehicles. For internal combustion engine vehicles, auxiliary brake such as engine brake can be used to alleviate the thermal load caused by the continuous braking of the friction brake. For battery electric vehicles (BEVs), regenerative braking can be used as auxiliary braking to improve brake safety. And through regenerative braking, energy can be partly converted into electrical energy and stored in accumulators (such as power batteries and supercapacitors), thus extending the mileage. However, the driver's line of sight in the mountains is limited, resulting in a certain degree of blindness in driving, so it is impossible to fully guarantee the safety and energy saving of downhill driving. Therefore, taking a battery electric light truck as an example, the system proposed in this paper first analyzes the driver's driving intention, proposes the system startup and exit strategy, and then combines the geographic information system (GIS) mountain road information, downslope speed limit and vehicle parameters,…

Germany's Kempten University Adrive Living Lab will feature latest aVDS driving simulator to research ADAS stress levels.

Researchers at Germany's Kempten University of Applied Sciences plan to embark this year on autonomous vehicle (AV) and advanced driver-assist system (ADAS) programs that will include investigation of the safest ways to achieve handover of a vehicle when control is returned to a human driver. To do so, it is installing an AB Dynamics advanced Vehicle Driving Simulator (aVDS) that will help measure driver stress levels if the vehicle is not capable of performing a particular maneuver. The aVDS has been designed to provide high level R&D capabilities specifically for autonomous systems.
