Abstract

Purpose

The purpose of this paper is to realize a smooth and secure brake assistance system to avoid rear‐end collision of automobiles.

Design/methodology/approach

It is important to judge necessity of deceleration assistance as early as possible and initiate the assistance naturally in order to reduce rear‐end crashes. However, it easily results in driver's discomfort. In addition, deceleration profile of the automatic braking is also important to realize smooth collision avoidance. In this paper, a deceleration assistance control for collision avoidance will be proposed based on the formulated braking behavior models of expert drivers to realize smooth, secure brake assistance.

Findings

The proposed brake assistance system can realize smooth deceleration profile and appropriate final status of the two vehicles for various approaching conditions. In addition, experimental results using a driving simulator will show validity of the proposed system based on subjective evaluation. It is also shown that the system realizes smooth deceleration control even under existence of the interaction between human driver and the system.

Research limitations/implications

This paper does not deal with effect of the deceleration method on change of drivers' behavior, including driver's trust on the system. Over‐trust should be eliminated if any.

Originality/value

The originality of the paper is to derive smooth secure collision avoidance system based on the driver's perceptual risk model. This method can realize smooth collision avoidance behavior for the various approaching conditions with a unified simple algorithm.

Abstract

Purpose

Two-handed automobile steering at low vehicle speeds may lead to reduced steering ability at large steering wheel angles and shoulder injury at high steering wheel rates (SWRs). As a first step toward solving these problems, this study aims, firstly, to design a surface electromyography (sEMG) controlled steering assistance interface that enables hands-free steering wheel rotation and, secondly, to validate the effect of this rotation on path-following accuracy.

Design/methodology/approach

A total of 24 drivers used biceps brachii sEMG signals to control the steering assistance interface at a maximized SWR in three driving simulator scenarios: U-turn, 90º turn and 45º turn. For comparison, the scenarios were repeated with a slower SWR and a game steering wheel in place of the steering assistance interface. The path-following accuracy of the steering assistance interface would be validated if it was at least comparable to that of the game steering wheel.

Findings

Overall, the steering assistance interface with a maximized SWR was comparable to a game steering wheel. For the U-turn, 90º turn and 45º turn, the sEMG-based human–machine interface (HMI) had median lateral errors of 0.55, 0.3 and 0.2 m, respectively, whereas the game steering wheel, respectively, had median lateral errors of 0.7, 0.4 and 0.3 m. The higher accuracy of the sEMG-based HMI was statistically significant in the case of the U-turn.

Originality/value

Although production automobiles do not use sEMG-based HMIs, and few studies have proposed sEMG controlled steering, the results of the current study warrant further development of a sEMG-based HMI for an actual automobile.

Abstract

Purpose

The purpose of this paper is to reveal how technology is being applied to augment drivers' skills and improve road safety throughout Europe.

Design/methodology/approach

The paper begins with a description of the European Commission's car safety initiatives, and why they are necessary. Then three driverassistance systems are examined in detail: adaptive cruise control, lane departure and lane‐changing systems, and driver vigilance monitoring.

Findings

Radar, lidar, and imaging sensors are being used and sometimes fused to build highly intelligent driver assistance equipment. The response of the system is crucial to its acceptance and success: false alarms or over‐violent actuation would lead to rejection. Neither must the system encourage over‐confidence. It is estimated that drowsiness detection could prevent 30 per cent of fatal motorway crashes.

Originality/value

The paper alerts engineers and drivers to a long‐term Europe‐wide project to develop and deploy driver assistance technologies.

Abstract

Purpose

Electric vehicles are well known for a silent and smooth drive; however, their presence on the road is difficult to identify for road users who may be subjected to certain incidences. Although electric vehicles are free from exhaust emission gases, the wear particles coming out from disc brakes are still unresolved issues. Therefore, the purpose of the present paper is to introduce a smart eco-friendly braking system that uses signal processing and integrated technologies to eventually build a comprehensive driver assistance system.

Design/methodology/approach

The parameters obstacle identification, driver drowsiness, driver alcohol situation and heart rate were all taken into account. A contactless brake blending system has been designed while upgrading a rapid response. The implemented state flow rule-based decision strategy validated with the outcomes of a novel experimental setup.

Findings

The drowsiness state of drivers was successfully identified for the proposed control map and set up vindicated with the improvement in stopping time, atmospheric environment and increase in vehicle active safety regime.

Originality/value

The present study adopted a unique approach and obtained a brake blending system for improved braking performance as well as overall safety enhancement with rapid control of the vehicle.

Abstract

Purpose

Advanced driving assistance system (ADAS) has been applied in commercial vehicles. This paper aims to evaluate the influence factors of commercial vehicle drivers’ acceptance on ADAS and explore the characteristics of each key factors. Two most widely used functions, forward collision warning (FCW) and lane departure warning (LDW), were considered in this paper.

Design/methodology/approach

A random forests algorithm was applied to evaluate the influence factors of commercial drivers’ acceptance. ADAS data of 24 commercial vehicles were recorded from 1 November to 21 December 2018, in Jiangsu province. Respond or not was set as dependent variables, while six influence factors were considered.

Findings

The acceptance rate for FCW and LDW systems was 69.52% and 38.76%, respectively. The accuracy of random forests model for FCW and LDW systems is 0.816 and 0.820, respectively. For FCW system, vehicle speed, duration time and warning hour are three key factors. Drivers prefer to respond in a short duration during daytime and low vehicle speed. While for LDW system, duration time, vehicle speed and driver age are three key factors. Older drivers have higher respond probability under higher vehicle speed, and the respond time is longer than FCW system.

Originality/value

Few research studies have focused on the attitudes of commercial vehicle drivers, though commercial vehicle accidents were proved to be more severe than passenger vehicles. The results of this study can help researchers to better understand the behavior of commercial vehicle drivers and make corresponding recommendations for ADAS of commercial vehicles.

Context awareness in assistive driving by probabilistic modeling techniques. Advanced techniques using Spatio-temporal techniques, computer vision and deep learning techniques.

Design/methodology/approach

Autonomous vehicles have been aimed to increase driver safety by introducing vehicle control from the driver to Advanced Driver Assistance Systems (ADAS). The core objective of these systems is to cut down on road accidents by helping the user in various ways. Early anticipation of a particular action would give a prior benefit to the driver to successfully handle the dangers on the road. In this paper, the advancements that have taken place in the use of multi-modal machine learning for assistive driving systems are surveyed. The aim is to help elucidate the recent progress and techniques in the field while also identifying the scope for further research and improvement. The authors take an overview of context-aware driver assistance systems that alert drivers in case of maneuvers by taking advantage of multi-modal human processing to better safety and drivability.
