Concept
Self-driving car
Summary
A self-driving car, also known as an autonomous car, driverless car, or robotic car (robo-car), is a car that is capable of traveling without human input. Self-driving cars use sensors to perceive their surroundings, such as optical and thermographic cameras, radar, lidar, ultrasound/sonar, GPS, odometry and inertial measurement units. Control systems interpret sensory information to create a three-dimensional model of the vehicle's surroundings. Based on the model, the car then identifies an appropriate navigation path and strategies for managing traffic controls (stop signs, traffic lights, speed limits, yield signs, etc.) and obstacles.
Once the technology matures, autonomous vehicles are predicted to impact the automotive industry, health, welfare, urban planning, traffic, insurance, labor market, and other fields. Their regulation is becoming an increasingly important issue.
Autonomy in vehicles is often divided into six levels, according to a system developed by SAE International (SAE J3016). The SAE levels can be roughly understood as Level 0 – no automation; Level 1 – hands on/shared control; Level 2 – hands off; Level 3 – eyes off; Level 4 – mind off, and Level 5 – steering wheel optional.
vehicles operating at Level 3 and above are an insignificant market factor. In December 2020, Waymo became the first service provider to offer driverless taxi rides to the general public, in a part of Phoenix, Arizona. In March 2021, Honda was the first manufacturer to sell a legally approved Level 3 car. Nuro began autonomous commercial delivery operations in California in 2021. Nuro was approved for Level 4 in Palo Alto in August, 2023. In December 2021, Mercedes-Benz received approval for a Level 3 car. In February 2022, Cruise became the second service provider to offer driverless taxi rides to the general public, in San Francisco.
In December 2022, several manufacturers had scaled back plans for self-driving technology, including Ford and Volkswagen.
