[h2 style="text-align: center;"]What is Tesla's Autopilot?[/h2][p]

[br]

[p]Autopilot is an optional driver-assist system for Tesla cars that Tesla CEO Elon Musk has promised will eventually turn the electric cars into fully self-driving vehicles.

[p]When Autopilot is engaged, cars can self-steer, adjust speed, detect nearby obstacles, apply brakes, and park. The technology uses a combination of radar, cameras, ultrasonic sensors, and GPS.

[p]Tesla says the onboard computers in its Autopilot-enabled cars released since October 2016 can support full self-driving capabilities, and that this functionality will be added via firmware updates over time, subject to regulatory approval.

[h2 style="text-align: center;"]Does Autopilot turn Tesla into fully self-driving cars?[/h2][p]

[br]

[p]Not yet. Currently, Autopilot is not rated as a fully self-driving system.

[p] Instead, Autopilot is currently classed as a Level 2 automated system by the US National Highway Transportation Safety Administration. Level 2 designation means Autopilot is capable of "combined automated functions, like acceleration and steering" but that the driver must remain engaged with driving at all times.

[h2 style="text-align: center;"]What can Tesla's Autopilot do?[/h2][p]

[br]

[p]*[span style="font-weight: bold;"]Traffic-Aware Cruise Control[/span]: Drives at the current speed limit, keeping a safe distance from the car ahead and adjusting speed for bends or cars passing in front. It is able to observe two cars in front of the vehicle.

[p][span style="font-weight: bold;"] *Autosteer[/span]: This feature keeps the car in the current lane and engages Traffic-Aware Cruise Control to maintain the car's speed, up to 90mph. It relies on various measures, including steering angle, steering rate, and speed, to gauge how to control the car. Drivers must keep their hands on the steering wheel, or else an alert goes off.

[p][span style="font-weight: bold;"]*Auto Lane Change[/span]: Enables the Tesla to automatically change lanes when Autosteer is engaged. Switching on the turning signal will cause the Tesla to move to the adjacent lane when safe.

[p][span style="font-weight: bold;"]*Side Collision Warning[/span]: This alerts drivers to objects, such as cars, that are too close to the side of the Tesla. When the car detects an object close to its side, fluid lines will radiate from the car's image in the Instrument Panel to alert the driver.

[p][span style="font-weight: bold;"]*Autopark[/span]: Automatic parallel parking, including the ability to automatically spot parking spots when driving at low speeds around cities.
Summon: Allows a phone app to automatically park a Tesla in or retrieve it from a home garage or driveway, and can also be set up to automatically control garage doors.

[p]Other features include Automatic Emergency Braking and Steering, Automatic High Beams, Blind Spot Detection, and Speed Assist.

[h2 style="text-align: center;"]Which sensors does Tesla's Autopilot use?[/h2][p style="text-align: center;"]

[br]

[p]Tesla says Autopilot's sensors allow the onboard computer system to build a detailed picture of its surroundings, allowing the vehicle to anticipate possible collisions with vehicles, pedestrians, cyclists, animals, debris, and other obstacles. It can also detect road markings, signs, and traffic lights.

[p]For drivers that opt for the Enhanced Autopilot and Full Self-Driving Capability, systems in cars launched since October 2016 rely on the following sensors.

[p][strong]Forward-looking radar:[/strong] The radar used by Autopilot can see up to 160m ahead of the car, through "sand, snow, fog—almost anything," according to Musk. Radar is the primary sensor used to detect the vehicle's surroundings, along with the front-facing cameras.

[p][strong]Eight cameras: [/strong]The four forward-facing cameras on the windshield of the car serve as a backup to the radar. The cameras consist of a narrow camera that captures footage 250m in front, a main camera that captures 150m in front, a wide-angle camera that captures 60m in front, and a camera that captures footage 80m in front and to the side of the car. The wide-angle camera is designed to read road signs and traffic lights, allowing the car to react accordingly.

[p][strong]Sonar: [/strong]A 360-degree, ultrasonic sonar detects obstacles in an eight-meter radius around the car. The ultrasonic sensors can spot objects like a child or a dog, and work at any speed. This feature can also detect objects in blind spots and assist the car when automatically switching lanes.

[p][strong]GPS: [/strong]A satellite navigation system can detect the car's position on the road.
