ELECTRIC POWER STEERING CONTROL APPARATUS AND METHOD

摘要

Disclosed herein are an electric power steering control apparatus and method. The electric power steering control apparatus includes a first determination unit which determines whether or not first current torque estimation information is in a first state of being out of a preset first reference torque estimation information range, a second determination unit which determines, if the first current torque estimation information is determined to be in the first state, whether or not second current torque estimation information is in a second state of being out of a preset second reference torque estimation information range, a drive unit which drives or shuts off an EPS device depending upon at least one determination of the first and second determination units, and a control unit which controls the drive unit so that the EPS device is driven or shut off.

1. An electric power steering control apparatus comprising:
a first determination unit which determines whether or not first current torque estimation information sensed by a first torque sensor is in a first state of being out of a preset first reference torque estimation information range; a second determination unit which determines, if the first current torque estimation information is determined to be in the first state, whether or not second current torque estimation information sensed by a second torque sensor is in a second state of being out of a preset second reference torque estimation information range; a drive unit which drives or shuts off an EPS (Electric Power Steering) device depending upon at least one determination of the first and second determination units; and a control unit which controls the drive unit so that the EPS device is driven if the first current torque estimation information is not determined to be in the first state or the second current torque estimation information is not determined to be in the second state, or the EPS device is shut off if the first current torque estimation information is determined to be in the first state or the second current torque estimation information is determined to be in the second state.
