Abstract
A steering control system and method for safe driving may control steering of a vehicle by sharing steering control information between control modules of the plurality of steering control devices through a communication channel even when abnormality such as a failure or fault occurs in one or some control modules included in the plurality of steering control devices.
Claims20
A system for controlling a steering motor, the system comprising:
- a first steering control device including a first input-side control module configured to generate first steering control information and a first output-side control module configured to control the steering motor;
- and
- a second steering control device including a second input-side control module configured to generate second steering control information and a second output-side control module configured to control the steering motor,
- wherein:
- the first output-side control module and the second output-side control module are configured to share at least one of the first steering control information or the second steering control information with each other,
- the second output-side control module is configured to, when the second input-side control module and the first output-side control module are determined to be in an abnormal state while the first input-side control module is determined to be in a normal state, control the steering motor based on the first steering control information generated by the first input-side control module of the first steering control device, and
- the first output-side control module of the first steering control device is configured to, when the first input-side control module and the second output-side control module are determined to be in the abnormal state while the second input-side control module is determined to be in the normal state, control the steering motor based on the second steering control information generated by the second input-side control module of the second steering control device.

A method for controlling a steering motor, the method comprising:
- generating first steering control information by a first input-side control module included in a first steering control device;
- generating second steering control information by a second input-side control module included in a second steering control device;
- sharing at least one of the first steering control information or the second steering control information by a first output-side control module included in the first steering control device and a second output-side control module included in the second steering control device;
- and
- controlling the steering motor by the first output-side control module and/or the second output-side control module, wherein the controlling of the steering motor includes:
- when the second input-side control module and the first output-side control module are determined to be in an abnormal state while the first input-side control module is determined to be in a normal state, controlling the steering motor using the second output-side control module using the first steering control information generated by the first input-side control module;
- and
- when the first input-side control module and the second output-side control module are determined to be in the abnormal state while the second input-side control module is determined to be in the normal state, controlling the steering motor using the first output-side control module using the second steering control information generated by the second input-side control module.
