Abstract:
1. A vehicle steering apparatus comprising: left and right arm mechanisms that connect a vehicle body to a vehicle wheel attachment portion attached with a vehicle wheel via front and rear arms disposed in a front-rear direction of a vehicle and having plural links rotatably connected to each other; an arm driving device that independently drives the left and right arm mechanisms so that each link angle corresponding to a turning angle of the vehicle wheel is determined; and a controller configured to wherein the controller controls the arm driving device so that each link angle changes within a range of maintaining a correlation in which the turning angle increases in accordance with an increase in the steering operation amount, and wherein a different correlation is set to each setting position so that a degree of an increase in the turning angle with respect to an increase in the steering operation amount changes before and after changing the setting position of the imaginary kingpin axis.
