Embedded System for Steering Assistance Based on Precise Geolocation 2017-36-0044
The focus of this study was to develop and validate a steering system assistance based on precise geolocation. The initial analysis was carried out using a mathematical model of a generic vehicle, to perform Matlab® simulations aiming to generate an algorithm capable of controlling the vehicle steering autonomously. Based on the results of those simulations it was possible to determinate that a RTK (Real Time Kinematic) would be a suitable technology for the geolocation system, meeting precision and control requirements. In order to validate the system in a real environment, a scale model RC car was equipped with a specific embedded electronic capable of recording the path driven and reproducing it autonomously. A HMI was developed making possible to visualize the vehicle during its operation. Coordinated with the vehicle, a remote cockpit with telemetry system emulates the steering wheel rotation. After all the tests, the system proved capable of reproducing predefined path with an average precision of 8 cm in favorable conditions.
