The Electronics and Telecommunications Research Institute (ETRI) along with the Korean electric car provider, IT Engineering, have together created new software for summoning and moving an autonomous vehicle using a voice recognition mobile application for phones.
Based on the levels from 0 to 5 suggested by the US automobile technology association, the autonomous driving technology tested here was being level 3 (eyes off) and level 4 (mind off), according to ETRI.
The newly developed technology enables a self-driving car to automatically produce and update a precise map that helps it apprehend the environment surrounding the road. The map has an error range of less than 10 cm which is outstanding in world standard.
The key technology uses sensors to recognize the surrounding environment on the road, creating and updating precision maps. Rather than ordinary maps, automated driving requires "precision maps" that include traffic lights, boundary stones, landmarks, and other parts of the driving environment. It is crucial that these information must be updated in as close to real time as possible.
The researchers also stated the significance of the electricity consumption rate by the self-driving car. Existing self-driving cars require hundreds of watts of electricity due to the large amount consumed in the sensor and AI algorithm operation processes. Thus, most testing has been conducted with midsize or larger sedans or sport utility vehicles (SUVs).
