The present disclosure relates to an apparatus for a non-contactive sensor having an ESD protection structure, and an apparatus for a non-contactive sensor having an ESD protection structure according to one embodiment of the present disclosure includes: a sensing member that acquires sense information emitted from a detection target object; a circuit board that is separately positioned below the sensing member and includes a sensor IC and one or more grounds; and an ESD protection element that is positioned on the circuit board and encloses a part of the sensor IC protruding on the circuit board.

Apparatus for non-contactive sensor having ESD protection structure

The present disclosure relates to an apparatus and a method for controlling an electric power steering motor, and the apparatus may include: a transceiver configured to receive information on a steering angle and information on an electric power steering motor and to transmit a control signal to the electric power steering motor; a motor operation determiner configured to recognize a rack stroke range and to determine whether a motor-limitation mode must be initiated or terminated based on the received information on the steering angle and electric power steering motor; and a motor control signal generator configured to generate a control signal corresponding to the determined initiation or termination of the motor-limitation mode.

Apparatus and method for controlling electric power steering motor

A steering apparatus, a steering method, and a steering control device. A steering motor includes a first winding and a second winding respectively receiving three-phase power. A first steering controller controls the power supplied to the first winding. A second steering controller controls the power supplied to the second winding. A detector detects whether or not a phase among three phases corresponding to each of the first and second windings is open; and a controller. If the phase among the three phases is detected to be open, the controller controls one steering controller corresponding to the open phase, among the first steering controller and the second steering controller, in accordance with an angular velocity of a steering wheel and the rotational speed of the steering motor, so that the steering motor generates additional torque.

Steering apparatus, steering method, and steering control device

The present disclosure relates a motor driving device that includes: an H-bridge circuit that includes first and second legs, each of which has one pair of switches, and supplies a driving current to a motor; a current sensor disposed between the H-bridge circuit and a voltage source; and a controller that acquires a first sensing signal from the current sensor for a first period of time during which a turn-on signal is supplied to a first switch disposed in the first leg or a fourth switch disposed in the second leg, to acquire a second sensing signal from the current sensor for a second period of time during which a turn-on signal is supplied to a second switch disposed in the first leg or a third switch disposed in the second leg, and determines an abnormality in the H-bridge circuit.

Device and method for driving motor

The present disclosure relates to a motor and a motor driven power steering system using the same. More particularly, the present disclosure relates to a motor adapted to maintain a balance of currents, and a motor driven power steering system adapted to reduce vibrations and noise and enhance steering quality using the same.
