PROBLEM TO BE SOLVED: To make automatic steering control cancelable during the specified time from the detection of a turn signal calling for a lane change by holding the steering angle of a steering wheel during the specified time. SOLUTION: Such a flow as undermentioned in repeated till the lateral displacement of one's own car to be based on a preceding lane changing the lane is steadily detected since a turn signal STS for a lane change has been read (S5). A controlling lateral displacement (y) is set to '0' (S19). Therefore, a steady front wheel steering angleδf O of becomes the same value as the value in time of inputting the turn signal (S38), and thereby a compensation front steering angleΔδfd comes to '0' (S42). Accordingly, the steady front steering angleδf O of the same value in time of turn inputting is set to a target front wheel steering angleδfd as it is left intact (S43). This target front wheel steering angleδfd is forcibly replaced to a holding valueδf OO fixed in time of the turn signal inputting (S45). Thus, a front wheel angleδf is held to the adjacent steering angle (S47). |
