Therefore, if the position is calculated based on reflected waves, there is a possibility that a preceding vehicle is erroneously detected as being in front of the own vehicle even though there is actually no preceding vehicle ahead of the own vehicle.

Embodiment Construction

[0016] Hereinafter, embodiments of the present invention will be described with reference to the drawings. A vehicle control device including an object detection device is mounted on a vehicle and has an ACC (Adaptive Cruise Control: Adaptive Cruise Control) function. The vehicle controller uses the ACC function to follow the host vehicle so that the distance between the preceding vehicle and the host vehicle detected by the object detection device becomes a target value of the inter-vehicle distance corresponding to the vehicle speed. In addition, the vehicle control device performs control so that the vehicle speed becomes the vehicle speed set as the target value when the preceding vehicle is not detected.

[0017] exist figure 1 Among them, the vehicle control device according to the present embodiment includes a radar device 11 , an image acquisition device 12 , a vehicle control ECU 13 , an engine ECU 14 , and a brake ECU 15 . In the vehicle control device, inter-vehic...

Abstract

Object detection for detecting an object existing within a detection range by transmitting a probe wave from a detection unit (11) and receiving a reflected wave reflected by an object (50), and acquiring the position based on the reflected wave as first detection information of the object A device (13) comprising: an image information acquiring unit that acquires second detection information of an object based on a position of an image of a detection range captured by the imaging unit (12); and a determination area setting unit that sets a determination area within the detection range. a determination unit; and an object position determination unit for determining the position of the object based on the first detection information when the first detection information and the second detection information exist in the judging area.

Description

technical field [0001] The present invention relates to an object detection technology mounted on a vehicle or the like for detecting objects existing around. Background technique [0002] Conventionally, there is known an object detection device that detects objects around a vehicle by transmitting millimeter waves or the like as probe waves at regular intervals and receiving reflected waves within a predetermined angle around the vehicle. [0003] In a vehicle equipped with such an object detection device, the position, orientation, and relative speed of other vehicles (vehicles ahead) existing in front of the vehicle in the direction of travel are calculated, and the vehicle speed is controlled so as to keep the same distance as the vehicle ahead. A certain distance (refer to Patent Document 1). [0004] Patent Document 1: Japanese Patent Laid-Open No. 2013-164390 [0005] In the object detection device described in Patent Document 1, a preceding vehicle is detected usi...
