Rule-based Reasoning in Onboard Devices: An Intelligent Route Guidance System

This paper described an intelligent route guidance system that implements rule-based reasoning according to integrated information in onboard devices. A knowledge base of rules is built, and a control method is designed to overcome deficiencies of embedded systems, such as small available storage and limited computing speed. A prototype system is developed and the experimental evaluation shows that it makes reasoning effective in onboard devices. This work improves the intelligence level of route guidance in vehicle location and navigation systems
