This research will delve into the design and implementation of such a system, focusing on its feasibility, effectiveness, and potential for enhancing the future of automotive technology.

2 Literature Review and Related Work

The continuous evolution of the automotive industry is well-documented through a wealth of existing research, which has progressively tackled the complexities of vehicle controls. Several studies have explored the possibilities and the nuances of secure keyless car ignition systems and mobile app controls for cars [1, 2], illustrating the technological trajectory that has led us to the current state of the industry.

Investigations into secure keyless car ignition systems have predominantly concentrated on the advancement of radio-frequency identification (RFID) and nearfield communication (NFC) technologies [3]. These studies have showcased the potential of keyless systems in improving security and user experience. However, they often underscore the vulnerability of such systems to relay attacks and the necessity for additional layers of security to mitigate such risks.

Likewise, research on mobile app controls for cars has spanned from conceptual frameworks to applied methodologies. The integration of diverse in-car systems into a single mobile application has been extensively studied, with the majority of research focusing on user interface design, real-time controls, and security implications [4, 5]. Nonetheless, there remains a noticeable gap in the literature concerning the holistic integration of such systems, particularly with the incorporation of real-time passenger detection and automated window control.

Existing systems, despite their significant advances, demonstrate notable limitations. The current keyless systems often lack robust multi-layered security protocols and hence may still be vulnerable to advanced malicious attacks. Moreover, while mobile applications have emerged as practical interfaces for controlling various aspects of a car, there is a striking absence of comprehensive solutions that integrate an array of controls into a single, user-friendly platform.

The realm of instrumented cars, vehicles endowed with sensors and actuators designed to gather data and provide enhanced interaction with the driving environment, is rich in both applied research and commercially viable products. It is a rapidly evolving domain that blends the fields of automotive engineering, computer science, and human–computer interaction.

Alongside, many studies focused on the integration of advanced sensor technologies within automobiles, laying the groundwork for the emergence of smart vehicles [6, 7].

The advent of the Internet of Things (IoT) brought a new dimension to instrumented cars. By connecting vehicles to broader digital ecosystems, numerous research works demonstrated opportunities for improved traffic management, efficient fuel utilization, and personalized in-car experiences. Indeed, the potential for vehicle-to-vehicle (V2V) and vehicle-to-infrastructure (V2I) communications has expanded the horizons of instrumented cars beyond the vehicle itself [8, 9]. Recent years have seen an exponential growth in instrumented car technology, notably with the rise of autonomous driving [10]. However, despite this advancement, a number of challenges persist in the domain of instrumented cars. Most notable are the issues of security, privacy, and usability. The need for user-friendly interfaces that can efficiently control and manage the multitude of functions provided by the instrumented car is an area that has not seen sufficient attention.

This present study seeks to address these concerns and contribute to the existing body of knowledge by proposing a Secure Keyless Car Ignition System and integrated mobile application controls. By leveraging an RFID-based ignition system, the security of vehicle operation is significantly enhanced. The mobile application offers a unified interface for the control of various elements of the car, optimizing the user experience. The inclusion of innovative features like GPS integration, real-time passenger detection, and Bluetooth-controlled window operation extends the capabilities of existing instrumented cars, making them safer, more user-friendly, and better integrated with other digital services.

At the heart of this investigation lies the Arduino platform—an open-source electronics platform centered on easy-to-use hardware and software. Arduino’s widespread adoption and straightforward programming language have made it a versatile tool for a wide range of applications, spanning from home automation to robotics, and even extending to automotive control systems [11]. Previous research has demonstrated Arduino’s suitability in managing complex tasks such as engine management, climate control, and even semiautonomous driving [12]. The inherent flexibility and accessibility of the Arduino platform make it an excellent choice for the implementation of our Secure Keyless Car Ignition System and integrated controls.

The study further builds upon several theoretical foundations encompassing secure keyless ignition, GPS integration, real-time passenger detection, and Bluetooth window controls. The principles of secure keyless ignition involve the use of encrypted digital signals for vehicle ignition, ensuring only authorized users can start the vehicle. GPS integration serves as a navigation aid and allows vehicle tracking, enhancing the security and functionality of the system [13]. Real-time passenger detection uses seat sensor data to monitor the presence and number of passengers in the vehicle [14], contributing to safety and customizability of the in-vehicle experience. Bluetooth window controls allow for wireless command of window positions [15], enhancing the convenience of vehicle operation.

These components, when isolated, each provide specific benefits. However, their true potential is realized when they are combined into an integrated system. This is where our conceptual framework comes into play. The framework envisages a system where these disparate technologies are harmonized under a single, user-friendly mobile application. The secure keyless ignition serves as the central pillar, around which the GPS, passenger detection system, and Bluetooth window controls revolve.

Conceptually, this implies the formation of a unified control environment where a user, through a single mobile interface, can securely ignite the vehicle, navigate roads, monitor passenger presence, and control window positions. By intertwining these technologies into one integrated system, we aim to create a seamless and enriched driving experience, one that elevates user convenience and security to new heights.

4 Implementation

The following sections elaborate on the implementation phase. Every component of the system was designed based on precise requirements and objectives.

4.1 Secure Keyless Car Ignition System

The Secure Keyless Car Ignition System is at the heart of our proposed design. It uses RFID technology to offer a reliable, touch-free ignition method. This system primarily consists of an RFID reader, distinct RFID tags, and their related encryption processes.

The RFID reader, linked to the Arduino microcontroller, is the bridge between the car and the driver. Every driver gets a distinct RFID tag, acting as their identifier. When the tag is placed in close proximity to the reader, the latter scans it, processes the encrypted data, and validates its authenticity. Upon successful validation, the microcontroller gets the go-ahead to initiate the car’s ignition.

Ensuring high security is fundamental in crafting the Secure Keyless Car Ignition System. The system incorporates cryptographic techniques to protect the data embedded in the RFID tag. A robust encryption algorithm is used to encode the unique identifier of each tag. This ensures that even if the tag’s data is intercepted during communication, it would be incomprehensible without the decryption key. Moreover, each tag is uniquely paired with the car’s RFID reader, thereby preventing unauthorized access even from duplicate or spoofed tags.

The development process entailed configuring the RFID reader and the Arduino to communicate securely, implementing the cryptographic algorithms, and programming the ignition initiation upon successful authentication. During the implementation, considerable emphasis was placed on ensuring the system’s reliability and responsiveness, as any delay or failure in the ignition process directly impacts the user experience.

Essentially, the Secure Keyless Car Ignition System enhances the traditional ignition process by incorporating secure, contactless technology. Its implementation underscores the integral role of security in the broader system and exemplifies the seamless fusion of advanced technology with traditional automotive systems.

4.2 Mobile Application Control

The Mobile Application Control plays an instrumental role in the proposed system, acting as the unified control interface for the user. The application is developed for both iOS and Android platforms, incorporating multiple functionalities such as an integrated dashboard, GPS navigation, real-time passenger detection, and Bluetooth-controlled window operation.

The design of our mobile app is rooted in a user-focused approach, promoting ease of use and seamless navigation. Its primary interface showcases a dashboard that offers live updates on various car metrics, including speed, fuel status, and engine temperature, to name a few. This information is sourced directly from the car’s diagnostic system, processed by the Arduino microcontroller, and transmitted to the app through Bluetooth. The app also incorporates a GPS feature, drawing on the car’s in-built GPS unit. This delivers both navigational aid and tracking capabilities. Besides aiding in direction, this dual-use tool adds a security dimension, offering the ability to pinpoint the car’s location when necessary. Another feature is the real-time passenger detection, utilizing pressure-sensitive sensors on the seats. This information is channeled through the Arduino to the app, which in turn visualizes the occupied seats, giving the driver a clear sense of passenger occupancy. The app’s window control capability enables users to operate the car’s windows remotely. Commands are sent from the app to the Arduino using Bluetooth, and windows are then adjusted with the help of servo motors.

Building this mobile app demanded meticulous coordination between the hardware input (via Arduino) and the software mechanics (within the app itself). This involved crafting a Bluetooth communication structure, designing dashboard and seat occupancy visuals, integrating GPS features, and establishing the window operation mechanism.

4.3 Dashboard Interface

The Dashboard Interface is central to the mobile app, offering users live updates on their vehicle’s condition. It was built based on principles of user-friendliness, visual attractiveness, and clear data presentation. While the digital dashboard emulates the conventional car dashboard, it has the added advantage of adaptability. It vividly presents several live vehicle metrics, including speed, engine RPM, remaining fuel, and coolant temperature, among others.

These parameters are captured from the vehicle’s onboard diagnostics system, processed by the Arduino microcontroller, and transmitted to the mobile application via the Bluetooth connection.

The design of the dashboard prioritizes readability and ease of understanding. Key parameters like speed and fuel level are displayed prominently, using intuitive gauges and meters that dynamically change in response to real-time data. Smaller icons and indicators provide additional information such as headlights status, seat belt warnings, and door ajar warnings, among others.

Interaction with the dashboard interface is intentionally kept minimal to avoid driver distraction. The focus is on information display rather than interaction. However, certain interactive elements, such as clicking on a particular gauge for more detailed data or settings, are incorporated. For example, a user could tap on the fuel gauge to view detailed fuel economy statistics.

In addition, the dashboard interface integrates alerts and notifications. These are triggered in response to specific events or when certain thresholds are reached—like critical fuel levels or excessive speed. These alerts appear as pop-up messages on the dashboard, thereby ensuring the driver is promptly informed of any crucial vehicle parameters.

4.4 GPS Integration

The GPS feature in the mobile app is multifunctional, acting both as a navigation tool and for vehicle tracking. Thus, the app seamlessly merges ease of use and safety features.

By tapping into the car’s built-in GPS unit, the system captures live location details. The Arduino microcontroller processes this data before it is sent to the mobile app via Bluetooth. Within the app, this information is interpreted, placing the car’s current position on a map using a built-in map service. This GPS feature primarily caters for two requirements. One, it acts as a navigation tool, offering step-by-step directions. Users simply set their desired destination in the app, and the map service plots the best path. The journey is visualized on the map, with live updates. On the other hand, this GPS feature also bolsters security by continuously monitoring the car’s whereabouts. If the car is lost or stolen, this system can pinpoint its location. Additionally, the system logs the vehicle’s past locations, further reinforcing its safety credentials.

From a technical point of view, the challenge was in guaranteeing smooth communication between the GPS unit, the Arduino, and the app, along with embedding the map service. Special attention was dedicated to the precision of the GPS readings and ensuring that the map interface reacted swiftly.

4.5 Real-Time Passenger Detection

The Live Passenger Detection system stands out in the mobile app, giving users an immediate view of which seats are occupied in the vehicle. It’s more than just a feature; it enhances awareness, security, and safety, complementing the multifaceted mobile control application. At its foundation, this system relies on pressure-sensitive sensors embedded in the car seats. These sensors gauge the weight on each seat, with the Arduino microcontroller deciphering this data to determine occupancy.

Once processed, this information is transmitted to the mobile app. Here, users see a current visual layout of the car’s seating. Seats with passengers light up, offering a quick glance at where everyone is seated. This display is straightforward and clear, using easily understood icons and color distinctions to mark filled and vacant seats.

In terms of its utility, the Live Passenger Detection system serves a dual role. It enhances a driver’s grasp of who’s in the car, invaluable in bigger vehicles like vans, minibuses or buses. Additionally, it bolsters safety by alerting the driver if a seat suddenly empties, signaling potential issues like a passenger not seated securely or a child seat concern.

Developing this feature required careful calibration of the seat sensors to ensure accurate detection of occupancy. The Arduino code had to be written to reliably interpret sensor data and communicate this information to the mobile application. On the application side, the interface for displaying the seating layout had to be designed and integrated.

4.6 Bluetooth-Controlled Window Operation

The Bluetooth-Controlled Window Operation feature extends the reach of the mobile application control into the physical aspects of the vehicle, offering a level of convenience and control that merges the digital and physical realms of the vehicle environment.

At the heart of this feature are servo motors installed within the window mechanism of the vehicle. These motors are controlled by the Arduino microcontroller, which interprets command signals sent from the mobile application and translates them into physical movement of the windows.

The mobile app offers a window control feature, allowing users to adjust individual or multiple windows as they wish. In the app, each window’s status is shown with an easy-to-use slider, making the interface straightforward.

In designing this feature, safety and prevention of unintentional operations were paramount. Users must confirm any window adjustment to avoid inadvertent changes due to accidental taps. Additionally, there’s a built-in safeguard: if anything obstructs a window while it’s moving, it’ll automatically stop, minimizing the risk of harm or damage.

The Bluetooth Window Control System's foundation lies in creating a steadfast Bluetooth connection between the app and the Arduino microcontroller. It was crucial to ensure precise transmission of commands and that the servo motors acted upon them correctly.

5 System Testing and Evaluation
