    摘要: In an ordinary case, a toe angle target speed restriction section (84A) operates in such a way that in a minimum value selection section (53) and a maximum value selection section (55), a tracking error Δα TIA is subjected to min-max processing, and that in an addition section (58A), a target toe angle value α T2P which has been subjected to first order correction, is added to the result of the aforementioned min-max processing, and the addition result is output to a target current computing section (86) as a target toe angle value α T2A . In this case, however, the toe angle target speed restriction section (84A) performs switchover control (changeover control) wherein, in a changeover control section (56A), a maximum value Δα Tmax is generated as a target toe angle change amount Δα T2 and is output. Subsequent to changeover control, the toe angle target speed restriction section (84A) performs hold control with respect to the attainment of a neutral position by a target toe angle value α T2A earlier than by a toe angle directive value α T1 .
