Object recognition system for vehicle
First Claim
1. An object recognition device for a vehicle that irradiates transmitting waves away from a subject vehicle, acquires data corresponding to objects around the subject vehicle on the basis of reflected waves of the transmitting waves, and recognizes the objects on the basis of the data, the object recognition device comprising:
- size determining means for determining a size of each of the recognized objects and that each of the recognized objects is large when at least a width of the recognized object is larger than a given determination value such that there is a high possibility that the recognized object does not exist;
existence condition determining means for determining whether at least a given number of the objects greater than two are determined to be large by the size determining means;
adverse condition determining means for identifying an adverse condition under which the objects cannot be normally detected when the given number of the objects are determined to be large by the existence condition determining means; and
control means for stopping vehicle travel control which uses the data acquired on the basis of the reflected waves when the adverse condition is identified.

Abstract
An object recognition device for a vehicle includes a size determining means, an existence condition determining means, and an adverse condition determining means. The size determining means determines that the recognized objects are large when a size of the objects is larger than a given determination value. The existence condition determining means determines whether at least a given number of the objects are determined to be large by the size determining means. The adverse condition determining means identifies an adverse condition related to recognizing the objects when at least the given number of the objects are determined to be large by the existence condition determining means.

17. An object recognition device for a vehicle that irradiates transmitting waves away from a subject vehicle, acquires data corresponding to objects around the subject vehicle on the basis of reflected waves of the transmitting waves, and recognizes the objects on the basis of the data, the object recognition device comprising:
-
size determining means for determining a size of each of the recognized objects and that each of the recognized objects is large when the size of the recognized object is larger than a given determination value such that there is a high possibility that the recognized object does not exist; existence condition determining means for determining whether at least a given number of the objects greater than two are determined to be large by the size determining means; and adverse condition determining means for identifying an adverse condition under which the objects cannot be normally detected when the given number of the objects are determined to be large by the existence condition determining means;
whereina determination is made taking the operation of a wiper into consideration when it is determined that the conditions are adverse.

18. An object recognition device for a vehicle that irradiates transmitting waves away from a subject vehicle, acquires data corresponding to objects around the subject vehicle on the basis of reflected waves of the transmitting waves, and recognizes the objects on the basis of the data, the object recognition device comprising:
-
size determining means for determining a size of each of the recognized objects based on a width and a depth of each of the recognized objects and that each of the recognized objects is large when the size of the recognized object is larger than a given determination value such that there is a high possibility that the recognized object does not exist; existence condition determining means for determining whether at least a given number of the objects greater than two are determined to be large by the size determining means; and adverse condition determining means for identifying an adverse condition under which the objects cannot be normally detected when the given number of the objects are determined to be large by the existence condition determining means. - View Dependent Claims (19, 20, 21, 22, 23)

24. An object recognition device for a vehicle that irradiates transmitting waves away from a subject vehicle, acquires data corresponding to objects around the subject vehicle on the basis of reflected waves of the transmitting waves, and recognizes the objects on the basis of the data, the object recognition device comprising:
-
means for determining a high possibility that each of the recognized objects does not exist when a width of the recognized object is larger than a given value; means for determining whether a specified number of the objects greater than two are determined to have the high possibility to not exist; means for identifying an adverse condition under which the objects cannot be normally detected when the specified number of the objects are determined to have the high possibility to not exist; and means for stopping vehicle travel control which uses the data acquired on the basis of the reflected waves when the adverse condition is identified.
