Intelligent Tire Using Energy-autarkic Microelectronics

Keywords: intelligent tire, tire pressure control system, energy-autarkic microelectronics

Tire pressure control systems are used for monitoring pressure and temperature of tires to avoid pressure fluctuations which influence the driving behaviour. Actual control systems use battery operated wheel electronics, which are mounted inside the tires.

To increase the life-time of the system and to avoid batteries it is necessary to integrate an energy-autarkic converter as a supply for the electronic unit.

This paper presents the development steps from a state-of-the-art tire pressure control system towards an intelligent tire system. Emphasis is laid on the comparison of rim-based to tire-based energy conversion.
