摘要： In the present invention, control feasibility in a vehicle control system architecture is efficiently determined by performing determination based on control feasibility in a physical element based on a converted parameter when a logical architecture is arranged in a physical architecture. The present invention includes: an arrangement unit 101 that arranges a logical architecture 601, which includes a linkage of each of logical functions and an execution time constraint of the linkage, in a physical architecture 300; a delay time calculation unit 104 that calculates a processing delay time based on a converted parameter when the logical architecture 601 is arranged in the physical architecture 300; and a verification unit 102 that verifies whether a total of the processing delay time satisfies the execution time constraint.

摘要： Vehicle systems that implement action planning for a vehicle have had difficulty in maintaining safety in the event of a failure in a recognition device since these systems generate trajectories and control the vehicle on the basis of outside-world information recognized by recognition devices. The present invention was conceived in light of the aforementioned situation and addresses the problem of maintaining safety even in the event of a failure in a recognition device of a vehicle system. This problem can be solved by an action planning device having a failure detection unit for detecting a failure in an outside-world recognition unit and a trajectory generation/determination unit for executing an action on the occurrence of a failure on the basis of outside-world information outputted by the outside-world recognition unit, wherein the trajectory generation/determination unit takes an action for coping with the failure on the basis of failure information from the failure detection unit.

摘要： The purpose of the present invention is to provide a system in which the reliability of an automatic driving system can be excellently complemented by a different control system while the automatic driving system is effectively used. The vehicle control device outputs to a drive device one of a first control signal generated on the basis of automatic driving control information, and a second control signal generated on the basis of the relative information between a vehicle and a surrounding object. If an abnormality is detected in the automatic driving control information, the second control signal is output to the drive device in place of the first control signal.

摘要： In order to detect and prevent attacks in which the network is infested with unauthorized data to cause malfunction, the invention aims, on the basis of network cycle information, to detect errors and to prevent unauthorized data forwarding in a network system such as a vehicle-mounted network. This network device is provided with a communication unit which receives data, a time management unit which manages the reception time at which data is received, and a control unit which processes data. If, for received data used as a reference, first data is received having the same identifier and a reception interval shorter than a prescribed cycle, the control unit waits to receive data having the same identifier as the first data from the reception time of the received data used as a reference up until the prescribed cycle has elapsed, and if during this interval second data is received having the same identifier as the first data, the control unit determines that an error has occurred and performs cycle abnormality detection processing (see FIG. 1).
