This would take around 12.5 years considering a fleet of 100 vehicles driving nonstop. Based on the classical testing proposed in, automated vehicles need to drive around 275 million Km to demonstrate a performance superior to humans. In spite of the aforementioned advances, validation of some functionalities is a complex and tough task. The most important advances in this area include Cruise Control (CC) in high speed, dynamic stability control, pedestrian detection systems combined with collision avoidance, and semiautonomous parking. However, most of these solutions are restricted to high speed (i.e., more than 30 Km/h), with automation level 2, based on the SAE J3016 standard. Based on the last ERTRAC (European Road Transport Research Advisory Council) report, traffic jam assist systems are partially available in the market.

This problem is being currently tackled by authorities, industry, and research centers.Īutomated vehicles and Advanced Driver Assistance Systems (ADAS), as part of the Intelligent Transportation Systems (ITS), are considered as short and medium term solutions for the previous problem. This study shows that the annual cost associated is more than €4.9 billion. In Europe, more than 200,000 traffic jams have been identified across 123 cities in September 2016. Nowadays, traffic jam is a well-known cause of the increase in travel times, accidents, and fuel consumption in urban areas. A comparative analysis of results between simulated and real platform shows the effectiveness of the proposed framework for designing and validating longitudinal controllers for real automated vehicles. In addition, longitudinal actuators of a Renault Twizy are characterized through empirical tests. The simulated dynamics are calculated using a multibody vehicle model. Control algorithms include a classical PID, an adaptive network fuzzy inference system (ANFIS), and a Model Predictive Control (MPC). In that sense, this paper presents a use case where three longitudinal low speed control techniques are designed, tuned, and validated using an in-house simulation framework and later applied in a real vehicle. Therefore, robust and reliable virtual environments to test automated driving maneuvers and control techniques are needed. Simulation platforms emerge as a feasible solution. Validation of these systems using real vehicles presents important drawbacks: the time needed to drive millions of kilometers, the risk associated with some situations, and the high cost involved. In order to increase the level of automation new systems need to be tested in an extensive set of complex scenarios, ensuring safety under all circumstances. Advanced Driver Assistance Systems (ADAS) acting over throttle and brake are already available in level 2 automated vehicles.
