Autonomous Driving - Trends 2021

 In the Name of Allah, the most Gracious, the most Merciful

Overseas autonomous driving technology status

The development of autonomous driving technology is focusing on commercialization and product production rather than technology R&D, and the pace of development is accelerating. Global market company Navigant Research published a report on the competitiveness of 19 major global companies developing autonomous driving technologies and platforms. Competitiveness is compared based on vision, market entry strategy, partnership, production strategy, technology, sales/marketing/distribution, product quality and reliability, and classified into leading, competition, challenge, and subgroups. GM, Google Waymo, Daimler, and Ford formed the leading groups, PSA, Toyota, Volvo, Baidu, Navya, and Hyundai were competing groups, while Apple, Uber, Tesla, and Honda were evaluated as challenging groups. 



Google Waymo

Google's subsidiary Waymo is trying to solve problems such as lane keeping, which requires constant observation of the driver to create a system that can fully autonomously drive without a driver. Currently, it has completed an autonomous driving system of level 4 of the American Society of Automotive Engineers (SAE), which requires the driver's observation only under certain conditions. Waymo built a system that recognizes and reacts to obstacles and events around the car using lidar, cameras, radar, and other ancillary sensors. 


Waymo's autonomous driving software can be divided into three main stages: observation stage, behavior prediction stage, and planning stage. In the observation stage, objects around the road are recognized, what they are, and their speed, direction, and acceleration are measured. In the behavior prediction step, the recognized objects predict how they will behave around the road. Waymo can make predictions based on the experience of driving millions of miles. In the planning stage, based on the information obtained in the previous two stages, the car will plan which route to take. In their experience, they think defensive and timid driving is the safest. 


The Waymo system can create a map and locate a car through real-time information with a deep understanding of the physical environment such as road type, distance, and dimension. In addition, it is equipped with a system that collects and interprets data obtained through trial driving. A system was also developed to protect against hacking caused by internet connection. 



Tesla Autopilot

Tesla's Autopilot is Tesla's autonomous driving system and hardware that provides lane maintenance, car control, autonomous parking, and lane change with driver confirmation. Tesla aims to provide fully autonomous cars. 


Advanced autopilots adapt to traffic conditions, keep their lanes, and change lanes on their own without driver intervention. If you move from another arterial road to another arterial road and get close to your destination, you can get out of the arterial road by yourself and park your car automatically.



Current status of open self-driving platforms abroad

Baidu Apollo

Baidu unveiled the autonomous driving platform'Apollo 3.0' in July 2018. 'Apollo 3.0' is the level 4 level of the American Society of Automotive Engineers (SAE). Level 4 is a level that does not require driver intervention, but the driver must be on board in case of an emergency. 'Apollo 3.0' is equipped with a program that allows developers and partners to develop autonomous vehicles within three months. The program consists of autonomous parking, unmanned self-driving delivery, and unmanned self-driving shuttle service. 


In the case of valet parking, all vehicles can use the autonomous parking service at a cost of about $1509 (about 1.68 million won) by adding only a camera and an ultrasonic radar. You can also use autopilot kits, security systems, and operational scheduling solutions. In addition, interesting technologies such as Baidu's voice recognition software, facial recognition technology, fatigue symptom monitoring technology, and customized services are also installed. 


Based on this technology, Baidu plans to pilot ten 14-seater self-driving minibuses, Apollon, in Japan and China's Beijing, Shenzhen, Wuhan, and other cities this year in cooperation with Softbank's subsidiary SB Drive. Apollo is equipped with Baidu's autonomous driving platform Apollo. 



Autoware Foundation Autoware

Autoware was jointly developed by Nagoya University and Nagasaki University in Japan, and was released in August 2015, and is still being actively developed. Autoware is an application software developed based on the robot software platform ROS (Robot Operation System). When a 3D point map created using LiDAR is given in advance, Autoware compares the 3D point cloud data obtained from the LiDAR while driving to determine the location of the vehicle in real time. Once the location is determined, the driving route to the destination can be planned and autonomous driving can be performed by controlling the steering wheel, accelerator pedal, brake pedal, and gear stick. 

 
The figure schematically shows the operation process of Autoware. First, in the recognition step, the position of the host vehicle is identified on a three-dimensional point map using a lidar, and an obstacle is recognized with a camera. Second, in the determination step, a safe driving route is planned based on the identified information and the input final destination information, and a driving lane, an entrance lane at an intersection, etc. are determined. Third, in the driving step, the target steering angle and target speed of the vehicle are determined in real time according to the given driving path and transmitted to the vehicle control computer. Finally, the vehicle control computer manipulates the wheel, accelerator pedal, and brake pedal to achieve the delivered goal.

Overseas self-driving technology verification process status

Mcity Test Facility University of Michigan, USA

The Mcity Test Facility is a test site designed to test and simulate autonomous vehicles and technologies in urban and suburban environments. Mcity worked with the Michigan Department of Transportation to design a unique test facility that simulates the complex vehicles encountered in urban and suburban environments. Mcity is located on the University of Michigan's North campus site with approximately 16 acres of road and transportation infrastructure. It has about 5 lanes with obstacles such as intersections, traffic signs, signals, sidewalks, buildings, street lights, and construction barriers. 
 

Centre of Excellence for Testing & Research of AVs (CETRAN) 싱가폴

CETRAN (Centre of Excellence for Testing & Research of AVs), led by Singapore's Nanyang Technological Univercity, does not directly develop autonomous driving technology, but how the autonomous driving system should work, how to test it, and autonomous driving. Study how international standards for automobiles should be created. CETRAN considers the safety of automobile passengers first, and their goal is to make society trust autonomous vehicles such as public transportation. 
 

 


American Center for Mobility (ACM) Michigan, USA

The American Center for Mobility (ACM) offers a variety of autonomous driving test environments over 500 acres. ACM is a global center established for testing, verification, training, and product standard development for autonomous vehicles. It can be used by all businesses, governments, universities, etc
