Abstract
There is provided an estimated steering angle calculation device for a vehicle capable of suppressing deterioration in accuracy of an estimated steering angle even if vehicle wheels slips or is locked due to acceleration or deceleration of the vehicle. Although, when being accelerated during turning, tire gripping force of front wheels serving as a driving wheel increases and a difference between wheel speeds of the front wheels decreases so that an estimated steering angle θes relative to an actual steering angle θact tends to decrease, the deterioration in accuracy of the estimated steering angle θes due to this tendency can be suppressed by increasing a second contribution rate relative to the estimated steering angle θes on the rear wheel side and decreasing a first contribution rate on the front wheel side in accordance with an accelerator opening degree.
