    Abstract: The disclosure relates to a steering control device and method. Specifically, according to the disclosure, a steering control device comprises a first steering control module controlling a first reaction force motor to generate a reaction force torque for a steering wheel through a first inverter and a second steering control module controlling a second reaction force motor to generate a reaction force torque for the steering wheel through a second inverter. The first steering control module or the second steering control module generates the reaction force torque by conducting one of the first inverter and the second inverter when the first inverter and the second inverter fail.

    Abstract: The present disclosure relates to an active rear collision avoidance apparatus and method. The apparatus includes a sensor for acquiring information by detecting at least one of a preceding vehicle, a vehicle at risk of collision or other vehicles; and a controller for determining a possibility of collision between the vehicle at risk of collision and the host vehicle, determining a direction of avoidance preferentially from where an avoidable area exists in response to the driving of the vehicle at risk of collision, if the possibility of collision is higher than or equal to a threshold point, controlling the host vehicle to drive to avoid in the determined direction of avoidance, and controlling the host vehicle to drive to avoid a possible collision in response to a response to the transmitted avoidance request signal from the preceding vehicle and/or the other vehicle.
