a communication unit configured to obtain position information of another vehicle by vehicle-to-vehicle communication; and a determination unit configured to determine, based on the position information obtained by the communication unit and a detection result obtained by the detection unit, whether performance degradation of the detection unit has occurred. ### Claim 2 (depends on 1) The apparatus according to claim 1, wherein in a case in which the detection unit does not detect that the other vehicle is present in a position indicated by the position information, the determination unit determines that the performance degradation of the detection unit has occurred. ### Claim 3 (depends on 1) The apparatus according to claim 1, wherein in a case in which the detection unit does not detect the target, the determination unit determines, based on the position information obtained by the communication unit and the detection result of the detection unit, whether the performance degradation of the detection unit has occurred. ### Claim 4 (depends on 1) The apparatus according to claim 1, wherein in a case in which a target detection result of the detection unit does not change for a first time, the determination unit determines, based on the position information obtained by the communication unit and the detection result of the detection unit, whether the performance degradation of the detection unit has occurred. ### Claim 5 (depends on 4) The apparatus according to claim 4, wherein in a case in which the detection unit does not detect that the another vehicle is present in a position indicated by the position information, the determination unit determines that the performance degradation of the detection unit has occurred, and in a case in which the target detection result of the detection unit does not change for a second time which is longer than the first time, the determination unit determines that the performance degradation of the detection unit has occurred. ### Claim 6 (depends on 1) The apparatus according to claim 1, further comprising: a notification unit configured to notify, in a case in which the determination unit determines that the performance degradation of the detection unit has occurred, an occupant of the presence of an obstacle in a detection range of the detection unit. ### Claim 7 (depends on 6) The apparatus according to claim 6, further comprising: an obtaining unit configured to obtain information related to weather, wherein the notification unit sets a notification content based on the information obtained by the obtaining unit. ### Claim 8 (depends on 1) The apparatus according to claim 1, further comprising: a removal unit configured to perform, in a case in which the determination unit determines that the performance degradation of the detection unit has occurred, a removal operation of an obstacle on a detection range of the detection unit. ### Claim 9 (depends on 8) The apparatus according to claim 8, further comprising: an obtaining unit configured to obtain information related to weather, wherein the removal unit performs the removal operation based on the information obtained by the obtaining unit.
