Abstract
In a warning apparatus, a restriction unit performs restriction of the issuance of a warning about a ghost from an issuing unit. A trajectory calculator calculates an estimated trajectory of each of first and second target objects. A cancelling unit cancels the restriction of the issuance of the warning about the ghost from the issuing unit upon determination that a predetermined cancelation condition is satisfied for the first and second target objects. The cancelation condition includes a condition that a passing distance between the first and second target objects is larger than a predetermined distance threshold.
Claims6
A warning apparatus installed in an own vehicle, the warning apparatus comprising:
- an obtaining unit configured to obtain information about first and second target objects that are detected in respective right and left rear regions of the own vehicle by a radar module;
- a warning determiner configured to determine, based on the information about the first and second target objects, whether each of the first and second target objects is a warning candidate about which an issuance of a warning is required;
- an issuing unit configured to perform the issuance of the warning about the warning candidate to a driver of the own vehicle when the own vehicle is reversing;
- a restriction unit configured to:
- determine whether a predetermined restriction condition is satisfied for the first and second target objects;
- determine that, upon determination that the restriction condition is satisfied for the first and second target objects, one of the first and second target objects is a ghost, and the other of the first and second target objects except for the ghost is a warning target that is the warning candidate;
- and
- perform restriction of the issuance of the warning about the ghost from the issuing unit;
- a trajectory calculator configured to calculate an estimated trajectory of each of the first and second target objects in a rearward region, the rearward region being previously established behind the own vehicle;
- and
- a cancelling unit configured to cancel the restriction of the issuance of the warning about the ghost from the issuing unit upon determination that a predetermined cancelation condition is satisfied for the first and second target objects,
- the cancelation condition including a condition that a passing distance between the first and second target objects is larger than a predetermined distance threshold, the passing distance between the first and second target objects being defined as a minimum distance between the estimated trajectory of the first target object and the estimated trajectory of the second target object.
