Using an Improved Rule Match Algorithm in an Expert System to Detect Broken Driving Rules for an Energy-efficiency and Safety Relevant Driving System
Autor: Juan Antonio Ortega Ramírez, Emre Yay, Natividad Martínez Madrid
Publikováno v: KES
Vehicles have been so far improved in terms of energy-efficiency and safety mainly by optimising the engine and the power train. However, there are opportunities to increase energy-efficiency and safety by adapting the individual driving behaviour in
