The current unmanned craze began in 2005 with the DARPA Grand Challenge, organized by the US Department of Defense. In 2004, no teams completed the race, but in 2005, many teams successfully finished the wilderness competition, with Stanford University and Carnegie Mellon University taking first and second place, respectively. The following year, in 2007, the DARPA Urban Challenge moved the challenge to city road conditions, where Carnegie Mellon, Stanford, and Virginia Tech took first, second, and third places.
Through these competitions, the potential of driverless technology was proven to the world. Google saw the future of this technology and in 2009, Sebastian Thrun, head of the Stanford AI Lab and leader of the Stanford team in the DARPA challenge, joined Google. This marked the beginning of Google's efforts in autonomous driving, which eventually led to the formation of Google X in January 2010.
From 2009 to June 2016, Google’s autonomous vehicles had driven a total of 2,777,585 kilometers. By August 2016, they had traveled an additional 202,777 kilometers. As of now, their vehicles have accumulated over 5 million kilometers, with the latest technology achieving an average of 8,000 km between manual interventions. In December 2016, Google officially spun off its driverless business into Waymo, a separate company.
Tesla also entered the scene, offering an optional “assisted driving package†since late 2014, using Mobileye's ADAS technology. However, due to differences in technical approaches, Tesla ended its partnership with Mobileye in July 2016. Today, Tesla relies on eight surround cameras, one millimeter wave radar, and twelve ultrasonic sensors. The company aimed for full autonomy by the end of 2017 and complete operation by 2019.
Despite its ambitious goals, Tesla's system has faced scrutiny. In May 2016, a Tesla owner was involved in a fatal accident while using the autopilot feature, leading to legal and regulatory challenges. Tesla claims that its technology can achieve "fully autonomous" driving at Level 4, but users are still required to remain attentive.
Other players like Uber and Apple have also made significant strides. Uber launched its driverless service in Pittsburgh and San Francisco in 2016, while Apple, through its Project Titan, aimed to develop a completely autonomous electric vehicle. Although Apple later shifted focus to software development, its interest in the field remains strong.
When it comes to technical indicators, companies are evaluated based on metrics such as cumulative miles driven without human intervention. Google leads with over 5 million kilometers and an average of 8,000 km between manual interventions. Other companies, including Nissan and Uber, lag behind, highlighting the technological gap.
The rise of startups in the autonomous driving space has further fueled the industry's growth. Many companies are working on Level 4 technologies, aiming to achieve safety compliance and cost control. While the market is competitive, it is expected that only a few will emerge as leaders in the long run.
Unmanned driving is classified from Level 0 to Level 5 according to SAE standards. Levels 2 and 3 are considered "assisted driving," where the driver remains responsible for the vehicle. These systems are already commercially available, with costs dropping significantly, making them more accessible to consumers.
Sensor technology plays a crucial role in autonomous vehicles. LiDAR, in particular, is considered one of the most important sensors due to its high accuracy. However, the cost of LiDAR remains a challenge. Startups are working on solid-state LiDAR solutions to reduce costs and improve scalability.
Deep learning algorithms have also gained traction, with some companies exploring camera-based systems. However, the limitations of single-sensor approaches have led to a shift towards multi-sensor fusion, combining LiDAR and cameras for better performance.
While the driverless industry is growing rapidly, there are concerns about whether it is a bubble. According to Gartner's Hype Cycle, the technology is in the final stages of the bubble period. Whether or not it will succeed depends on continued technological advancements.
In China, the complexity of road conditions presents unique challenges. Unlike Silicon Valley, Chinese roads require specialized algorithms to handle diverse scenarios. Companies like Baidu and SAIC are working on developing systems tailored for the Chinese market.
The construction of "driverless towns" in China, such as in Shenzhen and Zhangzhou, reflects the government's support for the industry. These projects aim to create environments where autonomous vehicles can be tested and deployed effectively.
Overall, the driverless industry is at an exciting stage, with numerous players contributing to its development. While challenges remain, the future looks promising for autonomous driving technology.
