New Development boosting the Autonomous Vehicles Market
Posted On January 07, 2021
In today's world, self-driving cars have attained notable merit in mock trials when tested on real streets. However, it has been seen that they cannot adapt their movements as per other vehicles or agents on the road. It is true when it comes to driving maneuvers, such as changing lanes, turning one side at an unprotected intersection, or merging onto a crowded highway. Self-driving cars can find all these tasks challenging, whereas humans can execute them quite efficiently. It is because humans can figure out the goals of other drivers who are operating vehicles and can negotiate decisions such as which car gets to go first.
Bringing a significant development in the market of Autonomous Cars researchers have recently solved the problem mentioned above. They have created a technique known as "LUCIDGames." It is a computational technique that can envisage and plan adaptive routes for an autonomous vehicle.
The researchers developed this technique with the overall goal to provide self-driving cars the ability to identify the objectives that other vehicles near them may have so that they can plan more suitable paths in situations that consist of some degree of negotiation.
The system so created is made up of "an estimator and a decision-maker." An 'estimator' is a technique that helps identify goals that the other drivers have, and the "decision-maker" is an algorithm that manages the acceleration and steering angle of the autonomous vehicle. The decision-maker identifies the most suitable track that the car should take on the basis of the information collected by the estimator.
At the initial stage, an autonomous vehicle is not aware of the objectives that the cars driving alongside it have, and so the estimator presumes their goals. The self-driving vehicle tries to foretell the trajectory of other vehicles for the next few seconds. It then compares its own predictions to the happenings of reality. The guess that was the most on-point in envisaging the future is kept.
This technology also provides self-driving cars with adaptability based on the type of drivers it comes across on the street. For example, it can establish if a driver is incredibly aggressive. This ability provides the car to adapt its trajectories and movements such as driving a bit away from the vehicle that is being operated by the aggressive driver to reduce the risk of accidents.
In the future, this technique, "LUCIDGames," may help in enhancing the security and dependability provided by self-driving vehicles. It will allow them to anticipate the movements and actions of the other agents on the road and adapt themselves according to such movements. So far, this technology has only been evaluated in mock trials and needs to be tested on real autonomous cars.
