Patent ID: 7667636

Claim:
A vehicle control system comprising: a transmitter mounted on a vehicle for transmitting an electromagnetic wave toward a predetermined detection area; a receiver for receiving reflected waves of the electromagnetic wave transmitted by the transmitter and reflected from an object; an object detector for detecting the object based on one of the reflected waves received by the receiver, the reflected waves having a reception level greater than or equal to a detection threshold value; and a vehicle controller for controlling the vehicle based on a result of the detection by the object detector; an object-type discriminator for discriminating whether the object detected by the object detector is a moving object or a stationary object; and a stationary-object detection threshold value setter for setting a stationary object detection threshold value higher than the detection threshold value over a predetermined distance range, wherein, when a reception level of a reflected wave from the object, which is determined to be a stationary object, is less than or equal to the stationary object detection threshold value in the predetermined distance range, the vehicle controller determines that the stationary object is not an object for which the vehicle is controlled, and wherein, as said stationary object detection threshold value, there are set a first stationary object detection threshold value for a region of the predetermined distance range close to the vehicle and a second stationary object detection threshold value for a region of the predetermined distance range distanced from the vehicle, the second stationary object detection threshold value being set lower than the first stationary object detection threshold value.
