Software prevents accidents from autonomous vehicles (Part 2)

Before participating in road traffic, autonomous vehicles must demonstrate that they do not harm the others on the road. New software prevents accidents by predicting different variants of a traffic situation every millisecond. The other methodologies are shown in part 2 as below.

Streamlined models for swift calculations

This kind of detailed traffic situation forecasting was previously considered too time-consuming and thus impractical. But now, the Munich research team has shown not only the theoretical viability of real-time data analysis with simultaneous simulation of future traffic events: They have also demonstrated that it delivers reliable results.

The quick calculations are made possible by simplified dynamic models. So-called reachability analysis is used to calculate potential future positions a car or a pedestrian might assume. When all characteristics of the road users are taken into account, the calculations become prohibitively time-consuming. That is why Althoff and his team work with simplified models. These are superior to the real ones in terms of their range of motion -- yet, mathematically easier to handle. This enhanced freedom of movement allows the models to depict a larger number of possible positions but includes the subset of positions expected for actual road users.

Real traffic data for a virtual test environment

For their evaluation, the computer scientists created a virtual model based on real data they had collected during test drives with an autonomous vehicle in Munich. This allowed them to craft a test environment that closely reflects everyday traffic scenarios. "Using the simulations, we were able to establish that the safety module does not lead to any loss of performance in terms of driving behavior, the predictive calculations are correct, accidents are prevented, and in emergency situations the vehicle is demonstrably brought to a safe stop," Althoff sums up.

The computer scientist emphasizes that the new security software could simplify the development of autonomous vehicles because it can be combined with all standard motion control programs.

Software prevents accidents from autonomous vehicles (Part 1)

Before participating in road traffic, autonomous vehicles must demonstrate that they do not harm the others on the road. New software prevents accidents by predicting different variants of a traffic situation every millisecond. One of these methodologies called algorithm is mentioned in part 1. 

A vehicle moves toward a convergence. Another vehicle streams out of the go across the road; however, it isn't yet certain whether it will turn right or left. Simultaneously, a passerby ventures into the path legitimately before the vehicle, and there is a cyclist on the opposite side of the road. Individuals with street traffic experience will when all is said in the done survey, the developments of other traffic members virtually.

"These sorts of circumstances present a gigantic test for self-ruling vehicles constrained by PC programs," clarifies Matthias Althoff, Professor of Cyber-Physical Systems at TUM. "However, independent driving will possibly pick up the acknowledgement of the overall population on the off chance that you can guarantee that the vehicles won't jeopardize other street clients - regardless of how confounding the traffic circumstance."

Algorithms that peer into the future

A definitive objective when creating programming for self-governing vehicles is to guarantee that they won't cause mishaps. Althoff, who is an individual from the Munich School of Robotics and Machine Intelligence, and his group have now built up a product module that for all time investigates and predicts occasions while driving. Vehicle sensor information is recorded and assessed each millisecond. The product can compute all potential developments for each traffic member - if they hold fast to the street traffic guidelines - permitting the framework to look three to six seconds into what's to come.

In light of these future situations, the framework decides an assortment of development choices for the vehicle. Simultaneously, the program ascertains potential crisis moves in which the vehicle can be moved out of damage's way by quickening or slowing down without imperiling others. The self-ruling vehicle may follow courses that are liberated from predictable impacts and for which a crisis move alternative has been recognized.
