OPERATING VOLTAGE GENERATOR FOR VEHICLE-MOUNTED ELECTRONIC SUBASSEMBLY

摘要

PROBLEM TO BE SOLVED: To provide a device for generating an operating voltage for a vehicle- mounted electronic subassembly that is highly reliable and free of part replacement. SOLUTION: The device for generating an operating voltage for at least one electronic subassembly 5 mounted on a vehicle and a vehicle with a tire comprises a piezoelectric element 3 adapted to oscillate under a tire pressure fluctuation when the vehicle is started. An alternating voltage generated by the piezoelectric element is supplied to the electronic subassembly.
