Document Type and Number:
WIPO Patent Application WO/2016/078552
Kind Code:
A1
Abstract:
A steering power system for an electric vehicle and a method for controlling same are provided. The steering power system includes: a steering motor (M); a steering motor controller (10), configured to control the steering motor (M); a high voltage power battery (20), configured to output a first voltage; a low voltage storage battery (30), configured to output a second voltage; a buck DC-DC converter (40), configured to convert the first voltage into the second voltage for being supplied to the low voltage storage battery (30) when a high voltage system (70) works; and a boost DC-DC converter (50), configured to convert the second voltage into the first voltage. When the high voltage system (70) has an abnormal power failure, the boost DC-DC converter (50) converts the second voltage outputted from the low voltage storage battery into the first voltage for being supplied to the steering motor controller (10). The steering power system improves driving safety of the electric vehicle.
