3D road mapper PDR presentation Annual project (Part A) Semester 2014b Students: Hen Markovich Aharon Ya’akov Supervisor: Boaz Mizrahi
Introduction - Mobiwise • 3D Road mapping. • Learning the specific vehicle performance. • Prediction of the expected path. • Computing the optimal fuel consumption. • Real time indication to the driver. The main goal - fuel saving by a unique method:
General view Our project is here HUD OBD Android app
Project goal • Design and product a hardware for this application. • The HW will be divided to two separated modules: • The main module which contains the microcontroller, the sensors and memory. • A peripheral module which contains the connections to the OBD, the host and the power supply. • The first module is the “vehicle processor” and this is the component that should be sold. • The second module will be the base for exemplification and debug.
