Stability control device

摘要

The turning angle of the left and right front wheels is controlled based on an SBW command turning angle corresponding to the steering angle of a steering wheel mechanically uncoupled from the left and right front wheels and a disturbance suppression command turning angle to suppress the yaw angle generated in the vehicle by disturbance. The steering reaction force to be applied to a column shaft is controlled based on the steering angle of the steering wheel.

主权项

1. A stability 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 steer-by-wire turning amount calculation unit configured to calculate a steer-by-wire turning amount corresponding to a steering amount of the steering unit; a yaw moment detection unit configured to detect a yaw moment generated in a vehicle by disturbance; a suppression turning amount calculation unit configured to calculate a suppression turning amount to suppress the yaw moment; a turning control unit configured to control a turning amount of the turning unit based on the steer-by-wire turning amount and the suppression turning amount; and a steering reaction force control unit configured to control a steering reaction force to be applied to the steering unit based on the steering amount so as not to reflect the suppression turning amount on the steering reaction force.
