Designing a Vehicle Collison-Avoidance Safety System using Arduino

The future of automotive relies on the mechatronic and electronic systems. The worldwide growth of automotive towards electronic systems suggests that driverless cars would soon be the common commuters. With such improvements safety of the passengers becomes first priority for the manufacturers. Nowadays automobiles come with high end technologies and quick responsive electronic systems. In addition to the passive safety systems, active safety systems definitely avoid collision thereby reducing the chances of injury and death. This project shows the working of an active safety system that is collision avoidance system. To create the model, TINKERCAD software has been used and a detailed working is explained. As a result, the system detects traffic and can alert the driver and stop the vehicle before meeting the collision.

The Emergence Characteristics of Driver’s Intentions Influenced by Different Emotions

Drivers’ behavioral intentions can affect traffic safety, vehicle energy use, and gas emission. Drivers’ emotions play an important role in intention generation and decision making. Determining the emergence characteristics of driver intentions influenced by different emotions is essential for driver intention recognition. This study focuses on developing a driver’s intention emergence model with the involvement of driving emotion on two-lane urban roads. Driver emotions were generated using various ways, including visual stimuli (video and picture), material incentives, and spiritual rewards. Real and virtual driving experiments were conducted to collect the multi-source dynamic data of human–vehicle–environment. The driver intention emergence model was constructed based on an artificial neural network, to identify the influences of drivers’ emotions on intention, as well as the evolution characteristics of drivers’ intentions in different emotions. The results show that the proposed model can make accurate predictions on driver intention emergence. The findings of this study can be used to improve drivers’ behavior, in order to create more efficient and safe driving. It can also provide a theoretical foundation for the development of an active safety system for vehicles and an intelligent driving command system.

Analysis of results of investigation tests of the developed information and measuring active safety system of the vehicle

The research objective is the analysis of results of investigation tests of the information and measuring active safety system developed by FSUE “NAMI”. The practice of operation and performed studies show that modern foreign advanced driver assistance systems do not provide appropriate functioning under severe road and climate conditions of the Russian Federation creating unjustified risks and precluding from preventing a significant number of road accidents. This statement is applicable to driving on slippery surfaces, ice and snow, to the driving mode in traffic jams, in the absence of recognizable road marking, blinding of video cameras, insufficient visibility range and road lighting, etc. In order to ensure competitive ability and commercial attractiveness of the developed domestic information and measuring active safety system, within the scope of this work additional studies were performed regarding improvement of driver status monitoring functions with an expanded vector of the state of the controls and speed range, tire pressure monitoring with an expanded speed range and start-stop driving mode, dangerous obstacle approach warning and detection of deviation from the center of the lane with unrecognizable marking. In this paper, the results of investigation tests of improved functions are considered.

Enhancing Occupant Safety by Pre-active Seat Control for Out-of-seat Position before Autonomous Emergency Braking Operation

The pre-active safety seat (PSS) is a recently developed active safety system for securing occupant safety in out-of-seat position (OOSP), which was applied in the Hyundai Genesis G80 in 2020. However, there has not been sufficient quantifiable verification supporting the effectiveness of the PSS. The present study was performed to determine the effectiveness of the PSS for occupant safety in OOSP and to identify areas for additional improvement. Six test conditions were considered to determine the effectiveness of the PSS for augmentation of occupant safety in OOSP. Ten healthy men participated in the tests. Compared with the no PSS condition, maximum head excursion and neck rotation were significantly decreased in the PSS condition by 0.31–0.79-fold and 0.33–0.48-fold, respectively (p < 0.05). The PSS condition in which the seat pan was moved forward to the mid position showed a greater effect in reducing the characteristic motions related to submarining, compared with the condition in which the seat pan was moved rearward to the mid position (p < 0.05). These results suggested that PSS augments occupant safety in OOSP. This study provides valuable insights in ameliorating risks to the occupant in unintended seat positions before braking and/or collision.

Analysis and assessment of defectiveness of regulations for the yellow signal at the intersection

Imprecise and defective regulations should be eliminated in the operation of vehicles. The article discusses and evaluates the differences in legal acts regarding the requirements for the yellow signal at intersections with traffic lights. Poland has signed the Vienna Convention on signs and signals. When implementing it into Polish legislation, the original provision was changed slightly. The reason for the ban on entering the intersection during the yellow signal has been changed. As a result, an unfavorable situation arises for the driver without a good way out. In addition, a colloquial word was introduced, undefined – “rapid braking”. The changes introduced in relation to the Vienna Convention were analyzed and evaluated. Defects were found and the need and necessity of correction of the applicable provision were reported. The necessity to consider changing the provision in the Vienna Convention was also pointed out. There is a need to provide advance information about an upcoming change. These are activities in the operation of vehicles in road traffic from the area of active safety system. It may be possible to use e.g. a flashing signal in the final phase of displaying a solid green signal on the S1 signaling device for vehicles.
