In a vehicle control system, when an inter-vehicular distance between a subject vehicle and a preceding vehicle detected by a radar device is less than or equal to a predetermined value, automatic braking is performed or an alarm is activated to alert a driver to prevent a collision. A stationary object detection threshold value of a reception level of a reflected wave for detecting a stationary object is set higher in a predetermined region compared to a moving object detection threshold value of a reception level of a reflected wave emitted from the radar device for detecting a moving object such as a preceding vehicle. Thus, the system prevents a gate or an article in the roadway, which are not obstacles, from being erroneously recognized as obstacles. As such, unnecessary automatic braking and alarm activation for the gate and the article in the roadway can be prevented.
