STEERING CONTROL DEVICE |
摘要 |
The turning amount of a turning unit is controlled according to the steering amount of a steering unit mechanically uncoupled from the turning unit. A steering reaction force characteristic in which the larger the self-aligning torque, the larger the steering reaction force is set on coordinates with the self-aligning torque and the steering reaction force as coordinate axes. When the steering reaction force corresponding to the self-aligning torque is applied to the steering unit based on the steering reaction force characteristic, the steering reaction force characteristic is offset on the coordinates in such a direction that the closer the lateral position of an own vehicle to a white line, the larger the absolute value of the steering reaction force. |

1. A steering control device comprising:
a steering unit configured to receive steering input from a driver; a turning unit mechanically uncoupled from the steering unit and configured to turn a turning wheel; a turning control unit configured to control a turning amount of the turning unit based on a steering amount of the steering unit; a steering reaction force control unit configured to have a steering characteristic such that a steering torque increases in accordance with an increase of a steering angle, and to apply a steering reaction force to the steering unit based on the steering characteristic; a lateral position detection unit configured to detect a lateral position of an own vehicle relative to a white line; and an offset unit configured to offset the steering characteristic in such a direction that the closer the detected lateral position to the white line, the larger an absolute value of the steering reaction force. |
