Parking assistance system

The main goal of this project was the development of functions for an ultrasonic-based parking assistance system.

The project aimed to evolve the system from a basic parking distance control system (PDC) to a fully automated parking system (PLA). The development process started with creating application software for various configurations, including 4-, 8-, and 12-channel setups, featuring both acoustic and visual displays.

In the first step, the application software was developed to support the various configurations of the ultrasonic sensors. This involved implementing functions for obstacle detection and calculating safe parking maneuvers based on data provided by the sensors. The configurations included setups with 4, 8, and 12 channels, each utilizing a different number of ultrasonic sensors to ensure accurate detection and representation of the surroundings.

Alongside the software development, work was done on integrating acoustic and visual representations. This involved developing interfaces for outputting warning sounds and visually displaying the surroundings on the vehicle display. These functions were developed to provide the driver with both acoustic warning signals and visual cues during the parking process, indicating the position and distance of obstacles.

After implementing the application software and integrating the display functions, extensive testing was conducted to verify the functionality and reliability of the system. These tests included both simulations and real-world driving tests to ensure that the system operates reliably under various conditions. The tests were conducted in various parking environments to validate the accuracy and responsiveness of the system.

By evolving the system from a basic parking distance control system to a fully automated parking system, significant improvements in user-friendliness and efficiency of the parking process were achieved. The fully automated parking system enabled the vehicle to execute parking maneuvers autonomously, significantly enhancing convenience and safety for the driver.

Overall, the project ensured that the developed ultrasonic-based parking assistance system achieved high precision and reliability, providing both acoustic and visual aids that significantly facilitate the parking process. sensified was responsible for the successful execution of this project, ensuring that all project goals were achieved through the use of state-of-the-art technologies and rigorous testing methods. The system meets the high standards demanded by the automotive industry.

The project started with receiving and parsing a 90-page requirement document, followed by iterative development cycles that included two-week sprints. Technologies such as AUTOSAR 4.x, Vector CANoe, and MATLAB/Simulink were extensively utilized. The software architecture was refined using Enterprise Architect, and the CAN communication interface was adjusted accordingly. After initial development and internal testing, the software components were integrated into the final product and subjected to rigorous testing according to predefined test cases. The project team grew from four to seven members and successfully resolved all outstanding issues, delivering a robust PDC (Park Distance Control) feature. Further developments included adding visual components and adapting the software for electric vehicles to ensure a comprehensive and advanced parking assistance system.
