The prototype design and tests of vibration controlled driver warning system from the steering wheel

Abstract

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.

Identifying the effects of driving parameters on stopping distance to reduce accident risks

“…Miniature vibration motors have been positioned on the steering wheel and collect information obtained from sensors such as the acceleration sensor placed in the vehicle's gravity center, the proximity sensor placed on the rear bumper and the rain sensor. The tests were carried out under real road conditions; it was determined that the drivers are warned at the wheel with vibrations at different durations according to the scenario developed for unfavorable driving conditions [24].…”
