Abstract: A steering control system comprises: a first steering controller including a first input-side control module generating first steering control information and a first output-side control module controlling a steering motor; and a second steering controller including a second input-side control module generating second steering control information and a second output-side control module controlling the steering motor. The steering control system is configured to, when steering of a vehicle is unable to be controlled by the first steering controller and the second steering controller, receive autonomous driving steering information to control the steering of the vehicle or transmit the first or second steering control information to perform cooperative control, thereby enhancing safe driving and being capable of controlling the steering of the vehicle even when a failure occurs in one or more control modules included in the steering control system.

Abstract: A steering control system and method for safe driving may control steering of a vehicle by sharing steering control information between control modules of the plurality of steering control devices through a communication channel even when abnormality such as a failure or fault occurs in one or some control modules included in the plurality of steering control devices.

Abstract: A power supply device and method improve space utilization and reduce power consumption and costs by implementing a voltage doubler based on the voltage of input power and driving a switching unit to thereby optimize leakage current. The power supply device comprises: a first power converter modulating a first voltage of a power source and converting a frequency of the first voltage to output a second voltage lower than the first voltage; a second power converter converting a frequency of the second voltage to output a third voltage lower than the second voltage and a fourth voltage between the first voltage and the third voltage; a controller receiving the third voltage; a switch drive outputting a fifth voltage higher than the first voltage using the first and fourth voltages; and a switch unit controlling connection between the power source and a motor in response to the fifth voltage.
