Application of Fuzzy Logic Controller for Safe Braking System: An Anti-Theft Tracking

Automotive security has become more challenging with the increasing of sophisticated modern technologies nowadays. While the transformation of automotive has brought major advancement in efficiency, it also led to the possibility of new threats in automotive field such as vehicle theft. In Malaysia, an average of sixty vehicles get stolen every day. Numbers of vehicle’s security and safety devices or system has been marketed such as safety alarms, door jammer, gearshift lock and global positioning system (GPS) tracker. However, there are also few limitations of these devices such as easily disable, notify false alarm and requires strong cellular network for continuous tracking. This paper describes the preliminary research and application of fuzzy logic based controller for braking system of stolen vehicle. In our future study, this system will be incorporated in the anti-theft tracking device with smartphone integration. In this study, two input parameters are considered which are the vehicle velocity and the sight distance. The proposed system will assist the user or vehicle owner to decide for safe braking control. Thus, reduce the risk of property loss or life loss

Optimizing the Automotive Security Development Process in Early Process Design Phases

Security is a relatively new topic in the automotive industry. In the former days, the only security defense methods were the engine immobilizer and the anti-theft alarm system. The rising connection of vehicles to external networks made it necessary to extend the security effort by introducing security development processes. These processes include, amongothers, risk analysis and treatment steps. In parallel, the development of ISO/SAE 21434 and UN-ECE No. R155 started. The long development cycles in the automotive industry made it necessary to align the development processes' early designs with the standards' draft releases. This work aims to design a new consistent, complete and efficient security development process, aligned with the normative references. The resulting development process design aligns with the overall development methodology of the underlying, evaluated development process. Use cases serve as a basis for evaluating improvements and the method designs. This work concentrates on the left leg of the V-Model.

Low-cost Car Battery Security Alert System

This is a technical article that showcases a low-cost car battery security alert system that utilizes a multi-vibrator circuit into a dual-tone multi-frequency (DTMF) output (loud beep sound) alarm to monitor and safeguard the car battery from local theft. The entire circuitry is a simple one and low-cost in production. The incessant cases in which car batteries are stolen especially in developing countries is on the high side. And the cost of replacing car batteries is on the increase daily. Therefore, one needs to secure her car battery from street theft. Using both mechanical fastening and electronic security-based systems one could sleep with two eyes closed. The device serves as an electronic watchdog on the car battery in the car while it is parked outside the owner’s residence or elsewhere. The security system is provided with an internal rechargeable battery energizing the alarm circuitry, having a single-pole double-throw (SPDT) relay, and connected cables, with an output sound capable of alerting the neighbourhood. Whenever the car battery is disconnecting from the terminal heads or the loop cable is broken the connected alarm will be triggered and this will call the attention of the neighbourhood and the owner thereby deterring the intruder. The entire system was simulated using Circuit Wizard software with good results. The system was fabricated using discrete semiconductor devices that are relatively simple and available for operation and maintenance, packaged, and tested. The circuit voltage is 11.52 volts and draws a current of 3.79A resulting in a wattage of 44 watts. The device is affordable

Simulation of undular bores evolution with damping

Propagation of undular bores with damping is considered in the framework of perturbed extended Korteweg-de Vries (peKdV) equation. Two types of damping terms for the peKdV equation, namely linear and Chezy frictional terms, which describe the turbulent boundary layers in the fluid flow are considered. Solving the peKdV equation numerically using the method of lines shows that under the influence of damping, the lead-ing solitary wave of the undular bores will split from the nonlinear wavetrain, propagates and behaves like an isolated solitary wave. The amplitude of the leading wave will remain the same for some times before it starts to decay again at a larger time. In general the amplitude of the leading wave and the mean level across the undular bore decreases due to the effect of damping

Design and Implementation of an Intelligent Safety and Security System for Vehicles Based on GSM Communication and IoT Network for Real-Time Tracking

In recent years, the surge in car theft cases, often linked to illicit activities, has become a growing concern. Simultaneously, countries grappling with oil shortages have shifted towards converting vehicles to run on liquid propane gas, presenting new safety challenges for car owners. This paper introduces a novel integrated intelligent system designed to address the challenges of car theft and safety concerns associated with gas-based vehicles. By seamlessly integrating these concerns into a single system, it aims to achieve significantly improved performance compared to traditional alarm systems. The proposed system consists of three primary parts: the car security subsystem, an Internet of Things (IoT)-based real-time car tracking subsystem, and the car safety subsystem. Utilizing key technologies such as the Arduino Microcontroller, Bluetooth module, vibration sensor, keypad, solenoid lock, GSM module, NodeMCU microcontroller, GPS module, MQ-4 gas sensor, flame sensor, temperature sensor, and Bluetooth module, the system aims to provide a comprehensive solution for the mentioned issues. Furthermore, the vibration sensor plays a crucial role in identifying unauthorized vehicle operations. Its significance lies in detecting the vibrations emanating from the running engine. Concurrently, other modules and sensors are utilized for real-time tracking and enhancing vehicle safety. These measures include safeguarding against incidents like fire outbreaks or gas leaks within the gas container. Finally, after assembling the system, a practical test was conducted, yielding favourable performance results. This paper describes a meaningful step towards improving the protection and safety for the cars, simultaneously addressing the stealing prevention and gas-related accident alleviation
