It will receive input from all sorts of different parts of the vehicle.ĭifferent situations might favor different sensors. The state estimator will coordinate the input from all the sensors in the autonomous vehicle and create a keep the geolocation of the vehicle within the HDMap up-to-date. Secondly, the car needs a state estimator. Source: TechCrunch 2nd Key aspect: State estimator Thanks to the latest development in Machine learning techniques, particularly in convolutional neural networks, Autonomous vehicles can use Cameras for object detection and object identification.

This is all thanks to the advances in Computer-vision that have occurred in the latest years. It allows them to identify objects and people in the real world.

It is a global navigation satellite system (GNSS) that provides geolocation and time information to a GPS receiver anywhere on or near the Earth where there is an unobstructed line of sight to four or more GPS satellites (Find more here).Ĭamera: A camera is an important sensor in autonomous vehicles. If you need you an official definition here it goes: The Global Positioning System ( GPS), is a satellite-based radio navigation system owned by the United States government and operated by the United States Air Force. When you use your smartphone you might need to geolocate yourself in the planet you activate your GPS and suddenly you can you Google Maps or any other geolocation-dependant functionality. GPS: In simple terms we all know what GPS means. Currently, many vehicles already use Radar technology for collision prevention during parking. Radars are one of the simplest sensors we can have in an autonomous vehicle, the distance they reach is short but they are relatively cheap when compare to LIDAR. Radar: Is a detection system that uses radio waves to determine the range, angle, or velocity of objects (See more here).

With a LIDAR scan, we generate a cloud point (literally a dataset of points) which can be loaded and used to represent the real world. This technology is used to scan roads and buildings. LIDAR: Stands for Light Detection and Ranging, is a remote sensing method that uses light in the form of a pulsed laser to measure ranges (variable distances) to the Earth. The following are some sensors used in Autonomous Vehicles : Before we jumped into addressing these key aspects of autonomous vehicles there are a few background concepts that we need to address, such as the sensors used in autonomous vehicles. There are three main elements this car will need to become self-driving, namely, HDMap (High Definition Map) State and geolocation estimator and a motion manager. This article will address the enabling technologies that make a vehicle autonomous and how these technologies are integrated together to allow a car/truck/SUV to navigate streets autonomously.įirst, let’s imagine we have a car and we wish to make our car autonomous. Once we get there our vehicles will have no steering wheels.

But if the industry and academia keep the good work we might be there sooner than later. Currently, we are far from a level 5 automation since there are many situations in which autonomous vehicles are not good dealing with. Ranging from level 0 which are our daily-use utility vehicles, until level 5 which are vehicles where no human interaction is required. Various levels of autonomy have been defined by SAE International (Society of Automotive Engineers). When thinking about autonomous vehicles we consider the idea of a car that can take us from origin to destination without the need for human intervention.
