Title:
VEHICLE-MOUNTED DEVICE FOR DETECTING TARGET, AND METHOD THEREFOR
Document Type and Number:
WIPO Patent Application WO/2014/157435
Kind Code:
A1
Abstract:
Provided is a device that detects a target existing outside a vehicle. In this device, a search wave is emitted by a radar unit (4) at predetermined periodic search timings, a reflected wave of the search wave having been reflected by the target is received, and position information including at least information about a distance from a vehicle (100) to the target is acquired. Further, on the basis of the position information acquired at each of a plurality of search timings, a control unit (6) acquires a relative speed between the vehicle and the target. On the basis of the position information and the relative speed, the control unit (6) calculates a predicted collision time which is a predicted time it takes, at the current point in time, for the vehicle to collide with the target, and determines whether the target provides an object for drive assist on the basis of the predicted collision time.
