Abstract:
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. A vehicle control apparatus according to the present invention includes a calculation section configured to calculate a first risk level present on the left of the vehicle and a second risk level present on the right of the vehicle, a setting section configured to set a first control threshold for the left of the vehicle based on the first risk level and to set a second control threshold for the right of the vehicle based on the second risk level, a change section configured to change at least one of the first and second control thresholds based on the first and second risk levels, and a control section configured to control the vehicle based on the changed control threshold.
