Title:
DUAL-POWER SUPPLY DUAL-WINDING MOTOR STEER-BY-WIRE SYSTEM AND FAULT-TOLERANT CONTROL METHOD THEREFOR
Document Type and Number:
WIPO Patent Application WO/2021/114566
Kind Code:
A1
Abstract:
A dual-power supply dual-winding motor steer-by-wire system and a fault-tolerant control method therefor. The system comprises: a steering wheel (1), a steering column assembly, a road sensing assembly, a dual-winding motor steering actuating device, a power supply fault-tolerant device (24), a main controller (26), and an electromagnetic clutch (6). The present invention has motor winding and power supply dual hardware redundancy functions; when a single winding fails, the other winding can be driven by the power supplies to complete a steering action; when a single power supply fails, the windings can be driven by the other power supply to complete a steering action; when both the windings and the power supplies fail, a steering action can still be completed by mechanical steering; thus, a complete loss of steering capability of a vehicle caused by power supply or winding failure is avoided, and the vehicle steering safety is enhanced.
