Patent number: 11423661Abstract: An object recognition apparatus include a storage device and a processor. The storage device stores peripheral information and tolerance information. The tolerance information is information in which the degree of tolerance for the undetected object is represented for each class of the object. The peripheral information is acquired by a sensor device provided in the vehicle. The processor performs object recognition process for recognizing an object around the vehicle. In the object recognition process, the processor identifies the object and its class to be detected based on the peripheral information, and calculates the likelihood that is a parameter representing the probability of detection of the object. Further, the processor calculates a likelihood threshold corresponding to the object based on the tolerance information, and determines whether to output the identification result of the object based on the comparative between the likelihood and the likelihood threshold.Type: GrantFiled: July 13, 2020Date of Patent: August 23, 2022Assignee: TOYOTA JIDOSHA KABUSHIKI KAISHAInventors: Hiroshi Sakamoto, Ryosuke Fukatani, Hideyuki Matsui, Junya Ueno
