Novel Mechatronic Sensors for Irregular Movements of Autonomous Land Vehicles

In this paper, novel sensors using physical phenomena deduced from ultrasound waves are proposed to overcome problems of cost, availability and adaptability in the measure of position, velocity and tilt of Autonomous Land Vehicles. The true challenge for the Autonomous Land Vehicles concerns essentially the accurate perception of hazardous environments to receive faithful information about reality. Current sensors used nowadays are viewed very expensive, complicated and unable to give accurate measures without time delay. For that, our contribution is located in this context. At first, fundamental principle of ultrasonic waves and their specific physical properties are described to introduce their use in the proposed sensors. Mechatronic concepts of sensors are then detailed with the corresponding mathematical models. Indeed, online implementation and real time experiences are conducted to verify the effectiveness of measurements.
