ELECTRIC STEERING CONTROL APPARATUS AND CONTROL METHOD THEREOF

An electronic steering control apparatus to which a redundancy system is applied and which includes a first position controller and a second position controller. When communication is established between the first and second position controllers, the first position controller controls the position of a first motor based on command steering angles θ1 and θ2 from a control unit and feedback steering angles θm1 and θm2 from the first motor and a second motor, and the second position controller controls the position of the second motor based on the command steering angles θ1 and θ2 from the control unit and the feedback steering angles θm1 and θm2 from the first motor and the second motor.
