Target recognition apparatus
First Claim
1. A target recognition apparatus mounted to a vehicle, the target recognition apparatus comprising:
- a detecting unit that detects an object that is present in a traveling direction of the vehicle, and acquires information for estimation that is used to perform an object type estimation to presume whether or not the detected object is an object to be used in control for enabling the vehicle to perform a predetermined operation;
an estimating unit that performs the object type estimation based on the information for estimation, wherein when a predetermined first condition is met, the control for enabling the vehicle to perform a predetermined operation is prohibited or suppressed, the predetermined first condition indicating that erroneous estimation may occur in the object type estimation; and
an operation control unit that enables the vehicle to perform the predetermined operation when a predetermined second condition is met, the predetermined second condition indicating that the probability of collision between the vehicle and the object is high,wherein, when the first condition is met, the operation control unit suppresses or prohibits the control for enabling the vehicle to perform a predetermined operation when the second condition is met.

Abstract
A target recognition apparatus includes a detecting unit and an estimating unit. The detecting unit detects an object that is present in a traveling direction of a vehicle, and acquires information for estimation that is used to perform an object type estimation to presume whether or not the detected object is an object to be used in control for enabling the vehicle to perform a predetermined operation. The estimating unit performs the object type estimation based on the information for estimation. When a predetermined first condition is met, the control for enabling the vehicle to perform a predetermined operation is prohibited or suppressed. The predetermined first condition indicates that erroneous estimation may occur in the object type estimation.

9. A target recognition method comprising:
-
detecting, by a detecting unit for a target recognition apparatus mounted to a vehicle, an object that is present in a traveling direction of a vehicle, and acquires information for estimation that is used to perform an object type estimation to presume whether or not the detected object is an object to be used in control for enabling the vehicle to perform a predetermined operation; performing, an estimating unit for the target recognition apparatus, the object type estimation based on the information for estimation, wherein, when a predetermined first condition is met, the control for enabling the vehicle to perform a predetermined operation is prohibited or suppressed, the predetermined first condition indicating that erroneous estimation may occur in the object type estimation; and enabling, by an operation control unit, the vehicle to perform the predetermined operation when a predetermined second condition is met, the predetermined second condition indicating that the probability of collision between the vehicle and the object is high, wherein, when the first condition is met, the operation control unit suppresses or prohibits the control for enabling the vehicle to perform a predetermined operation when the second condition is met.
