Steering control apparatus
First Claim
1. A steering control apparatus comprising:
- a torque sensor for detecting driver'"'"'s steering force as a steering torque;
a motor for providing torque to a steering system;
a motor drive circuit for driving said motor;
a steering control section for calculating at least a target current for said motor based on said steering torque;
a motor control section for providing an instruction to said motor drive circuit based on said target current;
a steering control verification section for verifying an operation of said steering control section based on said steering torque and said target current; and
a motor control verification section for verifying an operation of said motor control section based on a predetermined state quantity of said motor drive circuit or said motor.

Abstract
A steering control apparatus of a simple configuration is adaptable so
A steering control apparatus of a simple configuration is adaptable so as to construct a redundant system from an input to an output system at low cost in a reliable manner. A torque sensor detects a steering torque, and a motor (3) provides torque to a steering system. A motor drive circuit (56) drives the motor, and a steering control section (53a) calculates at least a target current for the motor based on the steering torque. A motor control section (53b) provides an instruction to the motor drive circuit (56) based on the target current. A steering control verification section (54a) verifies an operation of the steering control section (53a) based on the steering torque and the target current. A motor control verification section (54b) verifies an operation of the motor control section (53b) based on a predetermined state quantity of the motor drive circuit (56) or the motor (3).
