The Prototype Design and Tests of Vibration Controlled Driver Warning System from the Steering Wheel

In this study, drivers are warned according to detected adverse driving conditions by miniature vibration motors positioned on the steering wheel by obtained information from sensors such as acceleration sensor placed in the center gravity of vehicle, the proximity sensor placed on the rear bumper and rain sensor placed in fender. For this purpose, two different electronic circuit boards are used including firstly center gravity placed in vehicle that has collected signals from sensors and secondly center steering wheel that controlled the miniature vibration motors placed on the steering wheel cover. Wireless communication was established between the two electronic circuit boards. Tests was carried out in real road conditions; it was determined that drivers are warned on steering wheel with vibrations at the different durations (180 Hz frequency) according to the scenario developed for adverse driving conditions using accelerometer sensor, proximity sensor and the rain sensor. It was seen that the developed prototype can be used on available vehicles with small modifications, with a simple montage for a vehicle in the production process.
