The Road to Autonomy: Autonomous Car Development in the USA
The United States has long been at the forefront of technological innovation, and the development of autonomous cars is no exception. Also known as self-driving cars or driverless cars, autonomous vehicles (AVs) are revolutionizing the way we think about transportation, with the potential to transform the automotive industry and beyond. In this article, we’ll explore the current state of autonomous car development in the USA, highlighting key players, milestones, and challenges along the way.
A Brief History of Autonomous Cars in the USA
The concept of autonomous cars has been around for decades, but it wasn’t until the early 2000s that researchers and engineers began to seriously explore the idea. In 2004, the Defense Advanced Research Projects Agency (DARPA) launched the Grand Challenge, a competition designed to encourage the development of autonomous vehicles. The competition was won by a team from Stanford University, led by Sebastian Thrun, who would later go on to co-found Google’s self-driving car project.
Over the next decade, autonomous car research and development continued to accelerate, with companies like Google, Uber, and Tesla leading the charge. In 2011, Nevada became the first state to pass legislation allowing for the testing of autonomous vehicles on public roads. Since then, numerous other states have followed suit, with the majority of AV testing now taking place in California, Arizona, and Michigan.
Key Players in Autonomous Car Development in the USA
- Waymo (formerly Google Self-Driving Car Project): Founded in 2009, Waymo is one of the pioneers of autonomous car development. With a vast portfolio of patents and a large fleet of test vehicles, Waymo is widely considered the leader in the field.
- Cruise (GM subsidiary): In 2013, General Motors acquired Cruise, a San Francisco-based startup that had been developing autonomous car technology. With a focus on ride-sharing and connectivity, Cruise is one of the most advanced AV programs in the country.
- Tesla: Elon Musk’s electric vehicle (EV) company has been making waves in the Autotech industry, with its advanced Autopilot system enabling semi-autonomous driving on highways and urban streets.
- Uber ATG: Uber’s Advanced Technology Group (ATG) has been working on autonomous car development since 2015, with a focus on self-driving taxis and ride-sharing services.
- Argo AI: Founded in 2016, Argo AI is a Pittsburgh-based startup that has attracted significant investment from Ford and Volkswagen. With a focus on Level 4 autonomy (more on that below), Argo AI is working on a comprehensive suite of AV technologies.
Autonomy Levels: Understanding the Jargon
Autonomous cars are categorized into levels, ranging from Level 0 (no autonomy) to Level 5 (full autonomy). Here’s a brief breakdown:
- Level 0: No autonomy, with the driver in full control.
- Level 1: Driver assistance, with the car assisting in specific tasks, like adaptive cruise control or lane centering.
- Level 2: Partial autonomy, with the car capable of taking control in certain situations, like highway driving.
- Level 3: Conditional autonomy, with the car capable of taking control in most situations, but requiring driver intervention in exceptional cases.
- Level 4: High autonomy, with the car capable of taking control in all situations, with no driver intervention required.
- Level 5: Full autonomy, with no human driver required, ever.
Advancements and Milestones
The development of autonomous cars in the USA has been marked by numerous advancements and milestones, including:
- First Self-Driving Taxi: In 2018, Waymo became the first company to launch a self-driving taxi service, in Phoenix, Arizona.
- Long-Distance Testing: In 2019, Cruise completed a 5,000-mile journey across the country, using autonomous vehicles.
- In-Situ Perception: Argo AI has developed an innovative perception system, which allows vehicles to understand their surroundings in real-time.
- Simultaneous Localization and Mapping (SLAM): Researchers at MIT have developed an advanced SLAM system, enabling autonomous vehicles to create accurate maps of their environment while navigating.
