What’s required to make a self-driving car work??
In
certain country, they have tried to undergo this technology for example Volvo
has been working on self-driving technology under the guise of safety features
for years and has explored the idea of road trains for commercial vehicles,
where front lorry guides a convoy.
The
Process – How It Will Work
The
bulk of the technology required for driverless car which is not all futuristic,
but it is the combination of different sensors with advanced computer vision
systems that makes it works. Many of vehicle use Lidar (light detection and
ranging). The function is to rotating laser, usually mounted on the roof, that
continually scans the environment around the car. Besides that, traditional
radar is also used for detecting distances to objects and cars, as are various
cameras, accelerometers, gyroscopes and GPS, which are all used in conjunction
to build a 3D picture of the environment around the vehicle.
Those
picture shows the example of Lidar which it can detect and scan the environment
around the car. To be more understand, Lidar technology allows for high accuracy,
larger coverage areas and increased speed and efficiency of data collection.
Next,
the most difficult or complex part is the software that collects all the data,
analyses it and actually drives the vehicle. The system must be capable to
recognise and differentiating between cars, bikes, people, animals, and other
objects as well as the road surface, where the car is in the build-in maps and
can be able to react to an often unpredictable environment. If the system is
failed function well, the vehicles might face the problem just not for the car
but also the surrounding. It might be harmful to other people or environment.
But with the help of the system that already implement in the car such as
anti-lock brakes, cruise control, lane assist, and active parking assist, it
can give a help for the system.
The example of lane assist
Other
than that, we can use sensors which can give information to the GPS, cameras,
radar. For cameras, it let the car’s computers see what’s around it. For the
radar, however, allows the vehicle to see up to 100 meters away in the dark,
rain or snow. If we use this sensor, it will provide you the raw information
and the computer will work for it. These sensors are necessary because
driverless car are adapting to a human driven world. Then in the future all
cars would be able to talk to each other in a connected vehicle environment.

the sensor works
