Design of a Highly Safe Model Vehicle for Rear-End Collision Avoidance Considering Multiple Faults of Sensors

Abstract

This paper presents design of a highly safe driving control system using different kinds of sensors and its evaluation in order to avoid the rear-end collision of the model vehicle. The feature of the control is that an appropriate combination of sensing information from different kinds of sensors is introduced to reduce the occurrence of multiple faults. It is shown in the results of analysis of numerical values that the reliability of the combination of different kinds of sensors is higher than that of the combination of the same kind of sensors. Moreover, the systematic design of the model vehicle is proposed, and it is also shown in the experiment that the rear-end collision avoidance can be achieved even if a fault occurs at any sensor.
