Title:
SUSPENSION APPARATUS
Document Type and Number:
WIPO Patent Application WO/2017/002617
Kind Code:
A1
Abstract:
This suspension apparatus detects a sky fault and/or a ground fault in distinction from a break. A compressor relay 22 is provided between a battery 21 and an air compressor module 5. The drive and stop of the air compressor module 5 is controlled by the compressor relay 22. A compressor driver 26 outputs a driving signal to the compressor relay 22. A ground-side voltage monitor 28 detects the driving voltage of the compressor relay 22. A pressure sensor 17 detects the pressure of air on the discharge side of the air compressor module 5. A microcomputer 30 of a controller 25 detects a ground fault and a break in the driving signal of the compressor relay 22, in distinction from each other, on the basis of the voltage value Vg detected by the ground-side voltage monitor 28 and the pressure value P detected by the pressure sensor 17.
