Title:
VEHICLE-MOUNTED MOTOR CONTROL DEVICE
Document Type and Number:
WIPO Patent Application WO/2014/199587
Kind Code:
A1
Abstract:
A vehicle-mounted motor control device, which drives a switching element group (63) to rotate a motor (64), and charges capacitors (50, 62) with a capacitor voltage, includes: a high-voltage unit to which the capacitor voltage is applied; a low-voltage unit to which an external voltage is applied from an external device (70); and a control means (65) which operates on the basis of a power supply voltage generated from the capacitor voltage or a power supply voltage generated from the external voltage. When the number of rotations of the motor (64) decreases and the capacitor voltage drops due to the collision of the vehicle, the control means (65) maintains a power source voltage capable of operating the control means (65) by driving the switching element group (63).
