Embodiment Construction

[0020] figure 1 The vehicle control device 1 shown in is mounted on a motor vehicle hereinafter referred to as a host vehicle, and is used to detect the position, direction (relative to the heading direction of the host vehicle) and the object (target object) of an object located in front of the host vehicle speed. The vehicle control device 1 is also used to recognize a target object as a preceding vehicle (ie, a vehicle directly ahead of the own vehicle on the same traveling path), and to control the speed of the own vehicle to follow the leading vehicle. Specifically (as a function of the incorporated obstacle detection device), the vehicle control device 1 judges the motion status of a detected target object such as a preceding vehicle, that is, judges whether the target object is stationary or moving.

[0021] Such as figure 1 As shown in , a vehicle control device 1 is based on an inter-vehicle distance controller 10 including a CPU (Central Processing Unit), input / out...

Abstract

An obstacle detection apparatus in a host vehicle derives the value of absolute speed of a target object such as a preceding vehicle, and the distance of the object from the host vehicle, and compares the absolute speed with a threshold value that is increased in accordance with increase in value of a parameter which adversely affects the accuracy of deriving the absolute speed of the target object, such as the distance of the target object from the host vehicle or the running speed of the host vehicle. A judgement as to whether the target object is stationary or in motion is made based on results of the comparison.

Description

technical field [0001] The invention relates to an obstacle detection device for installation in a motor vehicle. Specifically, the present invention relates to an obstacle detection device having a function of judging whether a detection object located in front of a host vehicle of the device is stationary or moving. Background technique [0002] It is known to detect objects (hereinafter referred to as target objects) that are located in the area in front of the own vehicle of the device and are potential obstacles, and to determine whether any detected target objects are the preceding vehicle (i.e., in the same travel path) Various types of on-board devices of another vehicle driving in front of the vehicle. It is known to use such an obstacle detection device in a vehicle control system that controls the travel speed of the host vehicle to follow the preceding vehicle by a certain separation distance. Typically, target object detection is based on transmitted waves (eg...
