Abstract

Traffic accidents at night are higher than in other periods, especially on a dark road. This study explores the impact of the dark road on driver behaviours when approaching a parked or slowed-moving vehicle at the front. An experiment was conducted on a racing track at night, with and without road lighting. Different sizes of obstacles were used to represent other vehicles as a lorry, a car, and a motorcycle. The results show that the obstacles can be detected by drivers much earlier with the help of road lighting, and they tend to increase their speed, probably preparing to overtake the obstacles.

Abstract

The advancement of automotive technology has led to the development of automated vehicles. The trend of passengers performing non-driving-related activities during travel was expected to continue in the future of automated vehicles. It is essential to discover the type of activities that the users prefer to improve the interior design of an automated vehicle. Past studies show that every country has different preferred non-driving related activities. The main objective of this study is to collect data on preferred non-driving related activities, specifically by Malaysians, using online questionnaires. 293 respondents answered the questionnaires in six (6) months. As a result, the top three (3) non-driving related activities in Malaysia are listening to music, calling or texting, and interacting with others. In addition, the most preferred seating position as a passenger, the most suitable travel duration to perform non-driving related activities uninterrupted, and the preferred seating configuration of the automated vehicle were also discovered. The outcome of this study will add knowledge for designing better future automated vehicles suitable for Malaysian users.

Abstract

This research studies the forces applied to various vehicle control arms through different static and dynamic conditions during acceleration and braking condition. This study is targeting the important role that control arms play in ensuring stability and dynamics of vehicles, particularly when electric powertrains are added to chassis platforms created for conventional internal combustion engine (ICE). The study was designed with three phases: Fundamental of control arm dynamics (Phase 1), math formulations into theoretical models (Phase 2) and then experimental validation using the real rail component measurements (Phase 3). Tests were carried out on a straight track at a speed of 15 km/h and 30 km/h targeting the rear axle in an accelerating and the front axle in a braking condition. Results indicated that at 15 km/h, the acceleration of the rear axle was between 0.63 g and 0.49 g whereas at 30 km/h it was between 0.68 g and 0.70 g. During braking at 15 km/h, the front axle's acceleration ranged from a minimum of 0.62 g to a maximum of 0.70 g. At 30 km/h, the acceleration ranged from a minimum of 0.73 g to a maximum of 0.81 g. This suggests that there is a marked disparity in the dynamic action or response of sprung mass and unsprung mass at the different loading conditions. It emphasizes the need for additional support in the control arms and better control over the forces when the electric powertrains will be introduced. All of these have laid a basis for further research aimed at improving the designs of the vehicle structures in advance for the emerging powertrain technologies.
