Autonomes Fahren / Selbstfahrendes Auto - Funktionsweise (Animation)
Résumé
TLDRAutonomous vehicles, such as those from Ria Way and Locomotive, use sophisticated technology to navigate and operate without human drivers. These vehicles recognize obstacles and stop when necessary, thanks to an array of sensors including LIDAR, ultrasonic, cameras, and radar. LIDAR, similar to radar, uses light beams to map surroundings, while cameras, supported by AI, identify road signs and maintain lanes. However, LIDAR and cameras are less effective in fog, necessitating the use of radar to detect larger objects. GPS and high-precision digital maps ensure accurate vehicle positioning, but when GPS is unavailable, onboard odometry calculations help maintain location data. Companies like Nvidia, Tesla, and AMD supply specialized processors for these autonomous systems.

Autonomous vehicles, such as those from Ria Way and Locomotives, utilize advanced technology to independently detect obstacles, interact with traffic signals, and transport passengers to desired locations. These vehicles employ sensors like LIDAR, ultrasonic sensors, cameras, and radar to perceive their environment. LIDAR, a crucial component, sends out light beams to create a 3D map of the surroundings, while cameras identify road signs and obstacles using AI. Radar helps maintain distance and detect obstacles, although it might miss smaller objects like pedestrians. The vehicles' precise positioning relies on GPS and high-definition maps, which include information such as traffic signs and speed limits. In areas where GPS is unreliable, additional data like wheel rotation can aid in location determination. All sensor data is processed by specialized processors from companies like Nvidia and Tesla, enabling autonomous navigation.
