Abstract
The positions of an object on the sideward position of a vehicle are detected at prescribed time intervals. An expected locus of the object is computed on the basis of the positions of the object detected at the prescribed time intervals. An expected locus of the vehicle is also computed. It is determined whether or not there is a danger of collision on the basis of both the expected loci of the object and the vehicle. In this configuration, a periphery monitoring apparatus can be proposed which is capable of determining the danger of collision on the basis of the mutual movements of the vehicle and object.
Claims9
A periphery monitoring apparatus for a vehicle traveling on ground comprising:
- object position detecting means having an in-vehicle monitoring means for monitoring the periphery of the vehicle to produce a monitoring signal representative of an environmental condition, said object position detecting means for detecting the positions of an object on coordinates set with respect to the position and monitoring direction of said monitoring means and at prescribed time intervals on the basis of said monitoring signal;
- movement quantity detecting means for detecting the position and movement quantity of said monitoring means in the monitoring direction which moves for a prescribed time while the vehicle moves;
- expected object locus computing means for computing a real locus of said object on the basis of the positions of said object and said movement quantity of the monitoring means and computing an expected locus of said object on the basis of said real locus of the object;
- expected vehicle locus computing means for computing an expected locus of the vehicle;
- and
- danger determining means for determining whether or not there is a danger of collision between the object and the vehicle on the basis of both the expected loci of the object and the vehicle.
A recording medium containing a processing program for determining a danger of collision of a vehicle traveling on ground and an object by a computer, said processing program to be executed by said comprising the steps of:
- detecting positions of an object on the periphery of the vehicle at prescribed time intervals;
- computing an expected locus of the object on the basis of the positions of the object detected by said object position detecting means;
- computing an expected locus of the vehicle;
- and determining whether or not there is a danger of collision between the object and the vehicle on the basis of both the expected loci of the object and the vehicle.
A recording medium containing a processing program for determining a danger of collision of a vehicle traveling on ground and an object by a computer, said processing program to be executed by said computer comprising the steps of:
- acquiring a monitoring signal representative of an environmental condition produced from an in-vehicle monitoring means for monitoring the periphery of the vehicle;
- detecting the positions of an object on coordinates at prescribed time intervals on the basis of said monitoring signal;
- detecting the position and movement quantity of said monitoring means in a monitoring direction which moves for a prescribed time while the vehicle moves;
- computing a real locus of said object on the basis of the positions of said object and said movement quantity of the monitoring means;
- computing an expected locus of said object on the basis of said real locus of the object;
- computing an expected locus of the vehicle;
- and determining whether or not there is a danger of collision between the object and the vehicle on the basis of both the expected loci of the object and the vehicle.
