Abstract

Nowadays, there are always been heard commercial vehicle involved in accident and the mainly caused by namely rollovers of lightweight trucks. There is higher rate of fatal and death rate compared to other types of crashes which rollover events resulting impact on both drivers and passengers. Several factor that contributes to the rollover events, leading to the fatal physical injuries and death. The main objective of this project is to develop a device called Rollover Warning Device (RWD) has been built for commercial vehicles that suit on those that which have much larger center of gravity height-to-track width ratio. This developed system eventually gathers all the information related to movement of the vehicle and evaluates its current capacity and load to stay stable using the rollover index algorithm created. The rollover index algorithm used in a rear-wheel drive (RWD) system determines the rollover index value by using the load transfer ratio (LTR). The block model parameters for the rollover index solution are observed by using MATLAB. All the information and index will be simulated in MATLAB/Simulink and determined to analyze the steering motion performed with different velocities. Odenthal rollover index have been improvise and shown in Truck Sim driving simulator and MATLAB/Simulink software. To make it succeed, modelling steering step maneuver at any different velocities and loads are applied using the Hardware-in-the-loop (HIL) simulation approach. The result produced shown that the improvised Odenthal rollover index algorithm provides a 12.3% of improvement in Time-To-Warn (TTW) for the driver to be aware of the situation. By that reason, it will allow Time-To-Respond (TTR) for the driver to carefully and efficiently carry out the counter action. The application of upgraded Odenthal rollover index algorithm much more success to overcome rollover events by enhancing a dependable warning system. Rollover Warning Device (RWD) also equipped with IoT support which will inform and notify any desired party whenever rollover events might to occur. This support will be very useful to allow any currier company to observe and monitor the truck driver for the safety purpose. For IoT support, the notification must be shown as soon as possible for the monitoring and data collection.
