A piece of anomaly detection data that is the subject of determination is referred to as target data. The position of a vehicle when an anomaly occurred is grasped based on the target data. The number of pieces of the anomaly detection data is defined as the number of pieces of the anomaly detection data output within a predetermined area from the position of the vehicle when the anomaly occurred that is grasped based on the target data among the anomaly detection data stored in the memory. It is determined that the possibility that the target data is generated due to repair of the vehicle is higher when the number of pieces of the anomaly detection data is greater than or equal to a predetermined number than when the number of pieces of the anomaly detection data is less than the predetermined number.

An intake air amount control apparatus for an internal combustion engine is provided with: an opening control mechanism and a variable valve mechanism, which control an intake air amount; an intake characteristics change mechanism for controlling the intake air amount by adjusting a parameter or parameters different from those of the above two mechanisms; and an intake amount control device for performing a cooperative control of these mechanisms upon the occurrence of any normal condition. The intake air amount control apparatus is also provided with: an abnormality detection device for detecting an abnormal condition in these three mechanisms; and a fail-safe device for controlling the intake air amount of the opening control mechanism out of these three mechanisms and controlling the other two mechanism, so as to fix their control amounts to constant values.

A control apparatus is provided for a valve actuating system which is operable to lift an intake valve or an exhaust valve of an internal combustion engine and includes a lift characteristic changing mechanism for changing a lift characteristic of the intake valve or the exhaust valve. The control apparatus calculates a target operation value of the lift characteristic changing mechanism, and calculates a realizable range of the operation value which can be realized by the lift characteristic changing mechanism, based on a controlled variable that can be given to the lift characteristic changing mechanism and at least one parameter related to an environment surrounding the lift characteristic changing mechanism. If the target operation value is not within the realizable range of the operation value, the control apparatus calculates a new target operation value to be within the realizable range.

In an advanced-cruise-assist highway system, an AHS center facility, which is an upper facility for on-road facilities, periodically receives diagnostic information from the on-road facilities, and when it is determined that any on-road facility is in the faulty state, communicates the information that the on-road facility is in the faulty state to on-road facilities upstream from the faulty on-road facility, and the on-road facilities having received the information on the fault in the downstream on-road facility communicates the information that the downstream on-road facility is in the faulty state via a road-to-vehicle communication facility to AHS vehicles having the possibility of entering a zone under control by the faulty on-road facility. Further the information that the downstream on-road facility is in the faulty state is displayed on information board which can be recognize by vehicles having the possibility of entering a zone under control by the faulty on-road facility.
