VEHICULAR PRESSURE CONTROL DEVICE

摘要

PROBLEM TO BE SOLVED: To improve assembling performance of a device; and to improve contact reliability of the signal transmission between a pressure sensor and an electronic control unit by easily separating and integrating a pressure control unit with built-in pressure sensor and the electronic control unit. SOLUTION: This vehicle pressure control device has a transformer 50 arranged between the pressure sensor 40 and the electronic control unit 30, supplying source electric power to the pressure sensor 40 from the electronic control unit 30 by the electromagnetic induction action and transmitting a signal to the electronic control unit 30 from the pressure sensor 40. The transformer 50 is composed of a first transformer part 50a having a first core 50a arranged in the electronic control unit 30 and a first coil 51 for winding a conductor on the first core 50a and a second transformer part 50b arranged in the pressure sensor 40 by opposing this first transformer part 50a and having a second core 55 and a second coil 56 for winding a conductor on the second core 55.
