Abstract

The use of vehicles in Malaysia has become a need and important to commute to the workplace and commercial business transportation. This necessity resulted in an increase in the number of cars on the road that eventually increase the number of accidents that resulted in the loss of life which is also one of the leading killers in Malaysia. Deriving from this phenomenon, car maintenance especially brake systems has become imperative that eventually become the main objective of this research to investigate the effect of different road terrains to brake pad wear. The experimental vehicle is operated in two different road terrains namely hilly and flat roads and each road terrain is set to complete 1000km of investigation traveled distance. Three main investigation parameters are brake pad thickness wear, the temperature generated from rubbing the brake pad with the rotor, and the brake force applied on the brake pedal. A CANedge external onboard diagnostic (OBD) logger is used to collect real-time data on the relevant parameters from the vehicle’s ECU for analysis. The result from the experiments found that the average brake pad wear rate during hilly roads is 53% higher than that of flat roads. Likewise, brake pad temperature generation on a hilly road is 34% higher than that on a flat road. However, the brake pedal force applied during braking is 60% higher on flat roads compared to on hilly roads. From the findings, data from the vehicle OBD2 and the brake pad wear can be analyzed to provide an electronic signal for indication of timely maintenance for the brake pad.

Abstract

Two-thirds of vehicle accidents in Malaysia occurred at the straight type of roads, followed by intersection-type roads. Despite the deployment of traffic lights on the road, accidents still occur which are caused by illegal maneuvers, speeding or misjudgment of other’s actions. Hence, motivated by the lack of previous research regarding causes of accidents on intersectional roads, this study aims to observe the pattern of the vehicles’ speed and turning angle during the right turn after the traffic stop at the intersection road. To obtain these parameters, video samples of vehicles at two types of intersections were obtained and analyzed via YOLOV7 and DeepSORT. The two road intersections researched are four-legged intersection and three-legged intersection. 153 and 35 vehicle samples were collected from these types of road intersections, respectively. It was observed that 78 and 75 vehicles exit towards the nearest and furthest lanes at four-leg controlled crossings on divided roads. While, at a single-lane to a dual carriageway road intersection, 26 and 9 vehicles exit towards the nearest and furthest lanes, respectively. From the research, 16.52 - 17.53 km/h and 67.57°-73.33° are the most optimal turning speeds and angles respectively for vehicles at four-leg controlled crossings. Whereas 14.48 - 15.51 km/h and 144.77° - 154.403° are the most optimal turning speeds and angles respectively for vehicles at a single-lane to a dual carriageway road intersection.

Abstract

The electric vehicles (EVs) market in ASEAN has seen rapid growth in 2024, driven by the global trend towards sustainable transportation and strong government support. Thailand, with strong government policies and extensive charging infrastructure, has emerged as a regional leader. Malaysia and Indonesia are still in the early stages of adoption, grappling with high vehicle costs, limited charging infrastructure, and public acceptance challenges. A bibliometric analysis of research output from 2015–2025 reveals an exponential growth trend in EV-related studies, with Malaysian universities leading the research focus. Despite differences in progress, Indonesia, Malaysia, and Thailand face similar challenges, including limited infrastructure, high cost of ownership, and the need for greater public awareness. Tailored policies, infrastructure improvements, and regional collaboration are critical for ASEAN countries to realize their potential as key players in the global EV transition.

Abstract

Collision avoidance (CA) systems have become a requirement in vehicles due to their ability to prevent collisions. Despite the implementation of these systems on the road, accidents still happen due to the lack of adaptability of CA systems corresponding to road environment nonlinearities and external disturbances. Hence, this research focuses on the effect of external disturbances, such as additional load distribution on the vehicle while avoiding obstacles. The deployment of the CA scenario, considering the presence of disturbance, was simulated in MATLAB Simulink, with the reference trajectory for the system obtained from a skilled driver in real-time experiments at different speeds. The objective of this study is to observe and analyse the effect of additional load disturbances on vehicle stability, especially when the driver countersteers to avoid an obstacle. An increase in the additional load percentage at each side of the vehicle produces excessive lateral force opposite to the direction of the vehicle. This scenario creates a significant load transfer phenomenon and directly causes the vehicle to oversteer and understeer while avoiding obstacles. It has been observed that human cognition plays a huge role in defining a reference trajectory at different speeds while avoiding an obstacle. The pattern of the reference trajectory also affects the magnitude of the load transfer phenomena, especially when the driver manoeuvres the vehicle aggressively.
