A New Driving Assistant for Automobiles

This paper introduces an inexpensive car security system which addresses the needs for broader area coverage around the vehicle and stronger indication signals to drivers. The new driving assistant features simple ultrasonic-based sensors, implemented at the two front corners and the two blind spots of the vehicle. In order to report the close-by objects to the driver, the system employs a multitude of feedback devices, including tactile vibrators attached to the steering wheel, audible signals, and an LED display mounted on the dash board. The sensor system and the feedback devices are controlled in real-time by microcontrollers over a wireless communication network The final prototype system was installed and tested on a ride-on toy car.
