An autonomous car, also known as a robotic car, self-driving car, or driverless car,[1][2] is a vehicle that is capable of sensing its environment and moving with little or no human input.[3]

Autonomous cars combine a variety of sensors to perceive their surroundings, such as radar, lidar, sonar, GPS, odometry and inertial measurement units. Advanced control systems interpret sensory information to identify appropriate navigation paths, as well as obstacles and relevant signage.[4][5]
