ELECTRIC POWER STEERING APPARATUS

摘要

The apparatus herein provided includes a plurality of systems including driving circuits (20a, 20b) for driving motor coils (3a, 3b) corresponding thereto, and a control unit (10) for controlling control values of the driving circuits (20a, 20b) wherein, when a fault occurs in at least one of the plurality of systems including the motor coils (3a, 3b), the control unit (10) decreases a control value of a system(s) in which the fault occurs from an ordinary time control value or stops the drive by the system(s) in which the fault occurs, and also increases a control value of another system(s) in which the fault does not occur to more than an ordinary time control value.

主权项

1. An electric power steering apparatus configured to assist in steering force of a driver by driving force of a motor having a plurality of independent motor coils, the electric power steering apparatus, comprising:
a plurality of systems including driving circuits provided for every one of the plurality of motor coils, for driving the motor coils corresponding to the driving circuits; and a control unit for controlling control values of the driving circuits, wherein, when a fault occurs in at least one of the plurality of systems including the motor coils, the control unit decreases a control value of a system in which the fault occurs from an ordinary time control value thereof or stops the drive by a system in which the fault occurs, and also increases a control value of a system in which the fault does not occur to more than an ordinary time control value thereof.
