Embodiment Construction

[0045] Hereinafter, the road shape estimation device 1 according to the embodiment of the present invention will be described. The road shape estimating device 1 according to the present invention is mounted on the own vehicle 100 and estimates the shape of the road on which the own vehicle 100 travels. Hereinafter, the road on which the own vehicle 100 travels is referred to as the own vehicle traveling road.

[0046] First, refer to figure 1 The hardware configuration of the road shape estimation device 1 will be described. in, figure 1 It is a block diagram showing an example of the configuration of the road shape estimation device 1 according to the embodiment of the present invention. Such as figure 1 As shown, the road shape estimation device 1 includes a radar device 11 and an ECU 12 . Furthermore, the ECU 12 is electrically connected to a vehicle control device 50 mounted on the own vehicle 100 .

[0047] Radar device 11 such as figure 2 What is shown is a devi...

Abstract

A road shape estimation apparatus, mounted to a vehicle, for estimating a shape of a road on which the vehicle runs, includes: an object detection section for detecting, as a plurality of detected points, a position of a stationary object which is around the vehicle; a starting point determination section for determining a starting point by selecting from among the plurality of detected points, based on a positional relationship between the vehicle and each of the plurality of detected points; a detected point connection section for sequentially connecting between the starting point and one of the detected points that is a point to be connected, so as to start from the starting point, and for thus grouping detected points; and a road shape estimation section for estimating, as a shape of the road, a shape of a connection line obtained by grouping the detected points.

Description

technical field [0001] The present invention relates to a road shape estimating device, and more specifically, to a road shape estimating device mounted on a vehicle for estimating the shape of a road on which the vehicle is traveling. Background technique [0002] Conventionally, an in-vehicle system has been developed that estimates the shape of a road on which a vehicle travels, controls the steering of the vehicle, or reports the risk of a vehicle collision based on the road shape. In such an in-vehicle system as described above, in order to properly control the vehicle, it is necessary to accurately estimate the shape of the road. Such a device for estimating the shape of a road is disclosed in Patent Document 1, for example. [0003] The vehicle road shape recognition device disclosed in Patent Document 1 detects the position and shape of a roadside stationary object such as a protective fence based on a plurality of detection points obtained from a radio wave radar. ...
