Driving control device

A driving control device mounted on an own vehicle equipped with an object detection sensor capturing front view images including objects in front of the own vehicle, the driving control device comprising a computer system including a central processing unit, the computer system being configured to provide:

• a target-following driving control function receiving the front view images transmitted from the object detection sensor, the target-following driving control function recognizing, extracting and selecting a target object from the front view images, and performing a target-following driving control of the target object;
• an inter-vehicle distance acquiring function acquiring an inter-vehicle distance between the own vehicle and the target object;
• a target acceleration setting function determining a target acceleration of the own vehicle so as to maintain the inter-vehicle distance detected by the inter-vehicle distance acquiring function within a target inter-vehicle distance during a period of the target-following driving control, and the target acceleration setting function increasing a target deceleration, which is the target acceleration of a negative value, according to increasing of a difference between the target inter-vehicle distance and the inter-vehicle distance acquired by the inter-vehicle distance acquiring function, and
• a deceleration correction function increasing the target deceleration detected by the target acceleration setting function prior to deceleration of the own vehicle, in response to
• a period during which the target-following driving control function continuously recognizes the target object being more than a predetermined period, and
• the inter-vehicle distance acquired by the inter-vehicle distance acquiring function being less than a predetermined distance.
