Abstract
The present disclosure relates to a steering control apparatus and method, and a steering system. The steering controller manages the access right to the shared resource so that the access to the shared resource shared with the other steering controller is not overlapped with the other steering controller by using the shared resource manager, and controls the steering of the vehicle by accessing the shared resource according to the access right to the shared resource.
Claims15
A steering control apparatus having a first steering control device comprising:
- a shared resource manager for managing an access right to a shared resource so that an access of the first steering control device to the shared resource shared with one or more second steering control devices is not overlapped with the one or more second steering control devices;
- and
- a controller for controlling a steering of a vehicle by accessing the shared resource by one of the first steering control device and the one or more second steering control devices according to the access right for the shared resource,
- wherein, when one of the first steering control device and the one or more second steering control devices accesses the shared resources, the controller controls the access of the other of the first steering control device and the one or more second steering control devices to be postponed for a predetermined period of time.
A steering system comprising:
- at least two steering controllers sharing a shared resource;
- and
- a communication network connecting the at least two steering controllers to each other,
- wherein each of the at least two steering controllers:
- manages an access right to the shared resource so that an access of one of the at least two steering controllers to the shared resource does not overlap with the other of the at least two steering controllers, and
- controls a steering motor by accessing the shared resource by one of the at least two steering controllers according to the access right for the shared resource,
- wherein, when the one of the at least two steering controllers accesses the shared resources, the controller controls the access of the other of the at least two steering controllers to be postponed for a predetermined period of time.
A steering control method comprising:
- managing an access right to a shared resource so that an access to the shared resource of each of a first steering controller and a second steering controller does not overlap with each other;
- and
- controlling a steering motor by accessing the shared resource by the first steering controller or second steering controller according to the access right to the shared resource,
- wherein, when the one of the first steering controller and the second steering controller accesses the shared resources, the controller controls the access of the other of the first steering controller and the second steering controller to be postponed for a predetermined period of time.
