A New Vehicle Intelligent Navigation Alarm System Based on SB5227 Microprocessor

The vehicle navigation alarm system has played an important role in avoiding traffic accidents, but the function singleness, structure faultiness and price highness are open questions for the existing products. A new multifunction intelligent navigation alarm system based on ultrasonic ranging microprocessor SB5227 is developed to caution the driver with speech and LED for over acceleration, hard braking, up/downhill, backing, high-speed, bad weather, etc. This system has the characteristics of better practicability, higher reliability and higher cost performance. It can be used to prevent traffic accident effectively when combined with GPS.
