Filed: 2018-11-15
Abstract: To suppress, even if disturbance is applied to a vehicle running by an automatic steering control and a yaw is likely to occur, staggering of the vehicle, and to accomplish an excellent travelling performance.SOLUTION: In an automatic steering control, when a disturbance is determined and a change amount f (Δθm) in a rotational angle of an EPS motor 8 is small (S5), a yaw rate yaw detected by a yaw rate sensor 13 is read (S7), and a yaw rate change amount f(Δy) is calculated on the basis of the yaw rate yaw (S8). Then, when the yaw rate change amount f(Δy) is out of an allowable yaw change range ±f(yo) (S9), a determination is made such that there is an impact of the disturbance by a bump steer, and a control amount corresponding to a counter torque Tα that cancels a change amount of a tow angle θs by the bump steer is added to feed-forward control by the automatic steering control. Thereby, the change amount of the tow angle θs is canceled, and thus staggering occurred on an own vehicle M is suppressed.SELECTED DRAWING: Figure 3
