Patent number: 8600657Abstract: According to conventional art, if there is an obstacle on the left of a vehicle, a control threshold value is set so as to avoid the obstacle. If the control threshold value is exceeded, the vehicle is controlled in accordance with a deviation quantity so as to return to a position where the control threshold avoids being exceeded. However, even if a risky oncoming vehicle is approaching the vehicle on the right, the vehicle is controllably moved toward the oncoming vehicle. Thus, disadvantageously, a driver has a sense of fear or discomfort.Type: GrantFiled: July 28, 2009Date of Patent: December 3, 2013Assignee: Hitachi Automotive Systems, Ltd.Inventors: Shinjiro Saito, Atsushi Yokoyama, Toshiharu Sugawara, Tatsuya Yoshida, Akira Takahashi
