The system employs audio signal processing and extracts features such as linear predictive coefficients (LPC), mel-frequency cepstrum coefficients (MFCC) and power spectrum coefficients (PSC). The features are extracted using time windows of 0.02, 0.05 and 0.1 seconds in order to find the best representative window for the signal properties which should also be as short as possible for active safety systems. In order to find the best feature space, a variance analysis based approach is considered to represent the road types as distinguished classes. Optimised feature space is classified using artificial neural networks (ANN). The results show that the designed ANN can classify the road types with 91% accuracy at worst condition. To demonstrate the value of the system, a case study including traction control application is reported.","PeriodicalId":35143,"journal":{"name":"International Journal of Vehicle Safety","volume":"7 1","pages":"209"},"PeriodicalIF":0.0,"publicationDate":"2014-03-31","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://sci-hub-pdf.com/10.1504/IJVS.2014.060167","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"66693399","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

In this research, the scene features a motorcycle suddenly appearing from a behind a line of vehicles in a congested street into the path of an oncoming car turning right at an intersection. As a result, the driver often only has less than one second before applying brake, that is to say, the permitted avoidance time is short. To avoid a collision between a vehicle turning right and an oncoming vehicle, it is important to predict the possibility of danger in the intersection and lower the vehicle speed while driving through the intersection. Driving behaviour in a collision was compared among different ages of drivers and manoeuvre differences before collision were confirmed. The analysis of the collision patterns and driver collision avoidance behaviour described above suggests that enhancing forward collision avoidance support systems.","PeriodicalId":35143,"journal":{"name":"International Journal of Vehicle Safety","volume":"7 1","pages":"17-17"},"PeriodicalIF":0.0,"publicationDate":"2014-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://sci-hub-pdf.com/10.1504/IJVS.2014.058239","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"66693031","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

For these purposes, at first, a trained neuro-fuzzy estimator is used for vehicle path prediction according to vehicle speed, applied steering angle and also their changes. Then, slip of each wheel will be controlled by an anti-slip fuzzy controller which has been designed for each wheel. Also, another fuzzy controller has been designed so as to control the yaw angle concerning the yaw error. Then, the difference between the left and the right wheels’ braking torques is used by the ASBS controller in order to decrease the yaw error. Considering a model of Three-Degree-of-Freedom for chassis modelling and One-Degree-of-Freedom Dugoff’s tyre model for each wheel, a series of Matlab/Simulink simulation results will be presented in order to validate the effectiveness of the proposed controller.","PeriodicalId":35143,"journal":{"name":"International Journal of Vehicle Safety","volume":"6 1","pages":"381"},"PeriodicalIF":0.0,"publicationDate":"2013-10-07","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://sci-hub-pdf.com/10.1504/IJVS.2013.056971","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"66692660","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This study aims to understand the mechanical behaviour of human thoracic ribs through the application of a variety of strain rates. In this experiment, embalmed ribs were tested in a three-point bending mode under three different rates of deformation ranging from 0.05 to 8 mm/s. Mechanical parameters such as maximum bending moment, maximum deformation, bending stiffness and energy absorption capacity were determined. The maximum bending moment and stiffness showed an increase by 53% and 8%, respectively, at the highest rate of deformation compared to the lowest. The ultimate deformation and energy absorbed also increased by 26% and 66%, respectively, in this range of deformation rate. This data confirm that bone is viscoelastic in nature and exhibits different mechanical properties that are a function of strain rate.","PeriodicalId":35143,"journal":{"name":"International Journal of Vehicle Safety","volume":"6 1","pages":"361"},"PeriodicalIF":0.0,"publicationDate":"2013-10-07","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://sci-hub-pdf.com/10.1504/IJVS.2013.056969","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"66692598","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

By carefully designing the gradient pattern of the core, the radar and blast wave attenuation performance of the structure can be improved through mathematical modelling and analysis. In this study, analytical models were first developed to predict the EM wave reflection and shock wave transmission of the sandwich structure designed. Based on the analytical models, a parametric study was performed to investigate the effect of gradient pattern on each of the two design objectives, and then a multi-objective optimisation was conducted to generate the optimal design. This new approach makes it possible to develop a multi-functional lightweight armour plate for military combat vehicle against radar surveillance systems and blast attack in battlefields.","PeriodicalId":35143,"journal":{"name":"International Journal of Vehicle Safety","volume":"6 1","pages":"320-332"},"PeriodicalIF":0.0,"publicationDate":"2013-10-07","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://sci-hub-pdf.com/10.1504/IJVS.2013.056966","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"66692526","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

In this paper, with the tyre brush model and the seven degree of freedom vehicle model, the vehicle driving system model is modelled, and the front and rear tyres blow-out process was simulated and analysed. The results show that the vehicle will become unstable after the blow-out. In order to ensure the vehicle back to the stable range, the sliding mode controller is designed with the differential braking method, and the yaw rate is controlled by adjusting the braking torque at the opposite side of the blow-out tyre. With simulation, the sliding mode controller can guarantee the vehicle stability, shorten the braking distance and realise the safety brake during the tyre blow-out process.","PeriodicalId":35143,"journal":{"name":"International Journal of Vehicle Safety","volume":"6 1","pages":"333"},"PeriodicalIF":0.0,"publicationDate":"2013-10-07","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://sci-hub-pdf.com/10.1504/IJVS.2013.056967","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"66692551","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Secondly, 12 types of EEG-based parameters are established and TOPSIS (Technique for Order of Preference by Similarity to Ideal Solution) is introduced to determine the optimal indicator of driver fatigue. Thirdly, the interested electrodes (Fp1, F7) are determined by MDS (multidimensional scaling). Finally, the evaluation model of driver fatigue is established with the indicator of Fp1 and F7. Experiment results verify that the efficiency has no significant difference between evaluations with two electrodes and 16 electrodes.

In this paper we put forward a simulation method of vehicle moment of inertia, in which the kinetic energy of the vehicle is replaced by the kinetic energy of the rotating flywheel, and the tyre-road friction coefficient is replaced by magnetic powder clutch. The amplitude of exciting current to the clutch has relationship with the friction coefficient, so as to provide a datum for testing the working status of ABS under various road conditions. The system can realise simulating test of single road surface, bisectional road surface and joint road surface.
