Self-driving cars work based on the command control systems and sophisticated technologies such as sensing systems and self-control based on artificial intelligence. These vehicles utilize details such as cameras, radar, lidar, and also ultrasonic detectors with a view to detecting objects, lane markings, pedestrians, and other cars. It occurs in real-time and helps self-driven automobiles determine how to maneuver in a split second.
Cameras are an essential element in the identification of traffic signals, road signs and lanes on the roads. These are able to obtain high quality images that vision systems that use artificial intelligence study to determine the potential risks and flow of traffic. Integrated with the deep-learning algorithms these systems constantly adapt with real world environment aptitude to prevent possible hazardous situations in driving.
Lidar (Light Detection and Ranging) is critically important for distance measurement. It uses laser emission sending out pulses that go round the surrounding objects, reflecting and building up a picture of the immediate space. Through this data, self-driving cars can be able to identify obstacles on the road even at night to avoid an accurate position and obstacle position. To combat this radar helps lidar to supplement it by identifying moving objects that are close by such as other vehicles or cyclists.

Close range ultrasonic sensors enhance safety of equipment and or personnel. These are used near the car to help in parking and other slow speed movements like identifying the presence of people or curbside. The use of sensors makes the car have a comprehensive and accurate perception of the environment where its movement is taking place due to the use of sensor fusion technology.
Autonomous driving is all about artificial intelligence decision-making. Machine learning algorithms allow analyzing data received from sensors, and anticipate the movements of nearby objects, as well as make driving actions accordingly. These models get modified as they are applied in real environments as well as simulations so as to enhance their ability to handle traffic incidents. Speaking of cooperation of AI with car sensors, self-driving cars become safer and more efficient on roads.
Conclusion
Self-driving cars work as safe transportation means since they combine the employment of hybrid sensing mechanisms and decision-making systems embedded in artificial intelligence. Cameras, lidar, radar and ultrasonic sensors give environment perception and AI lets them forecast and act in an efficient manner. Consequently, automated cars will go on evolving and become even safer and more efficient; this is the new form of transportation and innovation in the long run.
