STABILITY CONTROL DEVICE

摘要

A stability control device is provided that controls a turning amount of the turning unit based on a steer-by-wire turning amount corresponding to a steering amount of a steering unit that is mechanically detached from the turning unit and based on a suppression turning amount for suppressing a yaw angle that is generated to a vehicle by a disturbance. The stability control device corrects the suppression turning amount to increase as the lateral position of a host vehicle becomes closer to the white line, when controlling the steering reaction force that is applied to the steering unit based on the steering amount, without reflecting the suppression turning amount on the steering reaction force that is applied to the steering unit.

主权项

1. A stability control device by comprising:
a steering unit that receives steering input from a driver; a turning unit configured to turn a turning wheel that is mechanically detached from the steering unit; a steer-by-wire turning amount calculation unit programmed to calculate a steer-by-wire turning amount corresponding to a steering amount of the steering unit; a camera configured to capture a white line in front of a host vehicle; a lateral position detection unit programmed to determine a lateral position of the host vehicle with respect to a target white line, which is a white line that intersects with a host vehicle traveling direction; a yaw angle detection unit programmed to detect a yaw angle, which is an angle between the target white line and the host vehicle traveling direction; a suppression turning amount calculation unit programmed to calculate a suppression turning amount to suppress the detected yaw angle; a suppression turning amount correction unit programmed to correct the suppression turning amount by increasing the suppression turning amount to a corrected suppression turning amount as the lateral position of the host vehicle becomes closer to the target white line; a turn control unit programmed to control a turning amount of the turning unit based on the steer-by-wire turning amount and the corrected suppression turning amount; and a steering reaction force control unit programmed to control steering reaction force based on the steering amount, without reflecting the corrected suppression turning amount on the steering reaction force that is applied to the steering unit.
