  Hereinafter, the best mode for carrying out the present invention will be described based on examples.

  FIG. 1 is a schematic configuration diagram showing a vehicle and a center to which a vehicle operation permission control system according to an embodiment of the present invention is applied.

  In FIG. 1, reference numeral 10 denotes a center for managing a plurality of vehicles, and a host computer 20 is installed in the center 10. The host computer 20 includes various databases 30, a display unit 40, an input unit 50, a center side communication unit 60 including a wireless transceiver including a communication control computer, an antenna 61 thereof, a GPS (Global Positioning System) receiver, and the like. The GPS receiving unit 70 and its antenna 71 are connected to each other.

  Note that the GPS receiving unit 70 on the center 10 side receives radio waves from a plurality of communication satellites 80 via the antenna 71, and the center 10 is operated by calculating the position of the center 10 as is well known. The position accuracy of each of the plurality of vehicles to be managed is corrected.

  On the other hand, 100 is one of a plurality of vehicles managed by the center 10, and the vehicle 100 includes a plurality of ECUs 110, for example, E / G (internal combustion engine) control ECUs 110a, A / T (automatic). A transmission) control ECU 110b, an information control ECU 110c, an ABS control ECU 110d, a navigation (navigation) control ECU 110e, and the like are connected to each other via a network such as an in-vehicle LAN. Various actuators 120 and various sensors 130 are connected to the plurality of ECUs 110 (110a, 110b, 110c, 110d, 110e,...) Via an interface circuit (not shown), and from a wireless transceiver including a communication control ECU. A vehicle-side communication unit 140 and its antenna 141, a GPS receiver 150 including a GPS receiver, and its antenna 151 are connected.

  Here, the ECU 110a for E / G control has “A”, Ver. (Version) is “α”, the A / T control ECU 110b is “B” as an identification ID number, Ver. “Β”, the information control ECU 110c has an identification ID number “C”, Ver. “Γ” as the identification ID number “D”, Ver. "Δ" as an identification ID number for the navigation control ECU 110e, Ver. “Ε” is given in advance.

  As is well known, the GPS receiving unit 150 on the vehicle 100 side receives radio waves from the plurality of communication satellites 80 via the antenna 151 so that the navigation control ECU 110c sequentially calculates the current position of the vehicle. The

  Next, vehicle operation management by the center to which the vehicle operation permission control system according to the embodiment of the present invention is applied will be described. In the present embodiment, it is assumed that the center 10 manages the operation of one vehicle 100 among a plurality of vehicles.

  First, based on the flowchart of FIG. 2 showing a processing procedure of vehicle information transmission control in the communication control ECU in the vehicle side communication unit 140 used in the vehicle operation permission control system of this embodiment, refer to FIG. explain. This vehicle information transmission control routine is executed based on issuance of a time-limited operation permission signal to all ECUs 110 mounted on the vehicle 100 when an unillustrated IGSW (ignition switch) of the vehicle 100 is turned on for the first time. . As this time limit, for example, 30 [sec: second] is set in advance. The vehicle information transmission control routine after the first time is repeatedly executed by the communication control ECU for each signal interruption from the center 10.

  In FIG. 2, first, vehicle information is collected and stored in step S101. The vehicle information includes connection information and operating conditions of all ECUs 110 (110a, 110b, 110c, 110d, 110e,...) Mounted on the vehicle 100. Here, the connection information of all ECUs 110 is a connection pattern of all ECUs 110 to which identification ID numbers mounted on the vehicle 100 with vehicle ID numbers registered in advance in the center 10 are assigned, and The operating statuses of all ECUs 110 include output states for various actuators 120 related to the control functions of the individual ECUs 110, output states from various sensors 130 that detect driving states of the various actuators 120 based on the output states.

  Next, the process proceeds to step S102 to determine whether communication with the center 10 is possible. If the determination condition in step S102 is not satisfied, that is, communication with the center 10 is not possible, the process returns to step S101, and the same processing is repeatedly executed until communication with the center 10 is enabled in step S102.

  When the determination condition in step S102 is satisfied, that is, communication with the center 10 is possible, the process proceeds to step S103, and the vehicle information collected and accumulated in step S101 is transmitted from the vehicle-side communication unit 140 via the antenna 141. This is sent to the center 10 and this routine is finished. As will be described later, since the operation permission signals for all ECUs 110 mounted on the vehicle 100 transmitted from the center 10 are always timed, the vehicle 100 is requested to operate the next operation permission signal before this time period elapses. Vehicle information needs to be transmitted from the vehicle 100 to the center 10.

  Next, with reference to FIG. 1 based on the flowchart of FIG. 3 which shows the process sequence of the vehicle operation control in the computer for communication control in the center side communication part 60 used with the vehicle operation permission control system of a present Example. explain. The vehicle operation control routine is repeatedly executed by the communication control computer at each signal interruption of the above-described vehicle information that is an operation permission request transmitted from the vehicle 100 or at predetermined time intervals.

  In FIG. 3, first, in step S201, vehicle information transmitted from the vehicle 100 specified by the vehicle ID number is read. This vehicle information includes various actuators 120 related to the connection patterns of all ECUs 110 to which the identification ID numbers of the vehicles 100 accompanied by the vehicle ID numbers transmitted from the vehicle 100 described above are assigned and the control functions of the individual ECUs 110. And operating states of various sensors 130.

  Next, the process proceeds to step S202, and it is determined whether a special operation permission condition for the vehicle 100 is satisfied. As a special operation permission condition for the vehicle 100, for example, entering a maintenance factory at the time of a vehicle inspection in which various operation checks on the vehicle 100 are required can be considered.

  When the determination condition of step S202 is not satisfied, that is, when the special operation permission condition for the vehicle 100 is not satisfied, the routine proceeds to step S203 as a normal operation permission request, and the operation permission condition for the vehicle 100 is satisfied. Is determined. As the operation permission conditions for the vehicle 100, for example, there is no theft report, the connection patterns of all the ECUs 110 are matched, the various actuators 120 and the various sensors 130 are matched, and the like.

  When the determination condition of step S202 is satisfied, that is, when entering the maintenance shop at the time of vehicle inspection, or when the determination condition of step S203 is satisfied, that is, when the operation permission condition for the vehicle 100 is satisfied, the process proceeds to step S204. The time-dependent operation permission signal for at least one ECU among the ECUs 110 (110a, 110b, 110c, 110d, 110e,...) Mounted on the vehicle 100 identified by the vehicle ID number is transmitted from the center side communication. It transmits with respect to the vehicle 100 specified by the vehicle ID number via the antenna 61 of the part 60, and complete | finishes this routine.

  On the other hand, when the determination condition of step S203 is not satisfied, that is, when any one of the operation permission conditions for the vehicle 100 is not satisfied, there is a possibility that some abnormality has occurred in the vehicle 100, and the process proceeds to step S205. In step S205, an ECU function restriction signal for the ECU 110 mounted on the vehicle 100 is transmitted to the vehicle 100 specified by the vehicle ID number via the antenna 61 of the center side communication unit 60, and this routine ends. .

  Here, as a case where some abnormality has occurred in the vehicle 100, for example, it is assumed that a theft notification for the vehicle 100 is notified to the center 10 in advance. At this time, a vehicle operation stop instruction by an ECU function restriction signal is transmitted from the center 10 to the vehicle 100, for example, when the vehicle speed is 5 km / h or less, the fuel injection is stopped and the brake is applied. A series of controls for stopping the vehicle 100 over the vehicle can be considered. As a result, the stolen vehicle 100 cannot move within a predetermined distance from the original position, and the position information of the vehicle 100 at that time can be easily found by the center 10.

  Further, for example, in the case of theft by a tow truck or trailer movement, the vehicle operation is stopped by the ECU function restriction signal from the center 10 to the vehicle 100 after the notification of theft to the vehicle 100 is notified to the center 10 in advance. An instruction is sent. Then, the vehicle 100 is only started with a time limit and cannot normally travel, and the position information of the vehicle 100 at that time can be easily found by the center 10 immediately. .

  At this time, if the vehicle 100 stolen by the movement of the tow truck or trailer is transferred to an area where radio waves do not reach from the center 10, for example, overseas, the vehicle 100 is in a state where it cannot perform normal traveling at all as described above. Therefore, it can be expected to prevent such theft.

  Furthermore, it is assumed that the vehicle 100 enters a school zone or city area where the speed limit is 30 [km / h], for example. At this time, the vehicle 100 is forced to travel at a vehicle speed of 30 [km / h] or less by transmitting a vehicle operation speed instruction by the ECU function restriction signal from the center 10 to the vehicle 100. Vehicles with violent driving can be excluded from those ranges.

  As described above, mutual communication such as encrypted vehicle information and operation permission signals is frequently performed between the vehicle 100 to which the vehicle operation permission control system of this embodiment is applied and the center 10. And the transmission of the vehicle information from the vehicle 100 to the center 10 becomes an operation permission request, and based on the operation permission that is always the transmission of the time-limited operation permission signal from the center 10 to the vehicle 100 according to the operation permission request, The vehicle 100 is always operated. For this reason, when an emergency such as theft or abnormality occurs in the vehicle 100, it can be immediately recognized by the center 10 and appropriate measures can be taken.

  As described above, the vehicle operation permission control system according to the present embodiment includes the plurality of vehicles 100 and the center 10 that manages the operations of the plurality of vehicles 100, and performs mutual communication between the vehicle 100 and the center 10. The vehicle 100 has a plurality of ECUs 110 (110a, 110b, 110c, 110d, 110e,...) Having vehicle ID numbers and individually assigned identification ID numbers, and a plurality of ECUs 110 based on the identification ID numbers.

When connection information of a plurality of ECUs 110 and their operation status are received and the received contents satisfy the operation conditions, a time-limited operation permission signal is always sent to a plurality of ECUs 110 of the vehicle 100 specified by the vehicle ID number. And the control function is restricted or changed for at least one of the plurality of ECUs 110 of the vehicle 100 specified by the vehicle ID number, or when the received content does not satisfy the operating condition. Center-side communication means achieved by a center-side communication unit 60, an antenna 61, and the like that transmit a signal to be stopped is provided.

  That is, the connection information of the plurality of ECUs 110 that are mounted on the vehicle 100 with the vehicle ID number and are individually assigned the identification ID number and their operation status are sent to the center 10 according to a predetermined timing or a transmission request from the center 10. Sent. This is an operation permission request from the vehicle 100 to the center 10, and the connection information of the plurality of ECUs 110 by the identification ID number accompanied by the vehicle ID number from the vehicle 100 and their operation status are received at the center 10. If it is determined that the received content satisfies the operating condition, the time-dependent operation permission is always given to the plurality of ECUs 110 of the vehicle 100 specified by the vehicle ID number as the operation permission issuance from the center 10 to the vehicle 100. A signal is transmitted. On the other hand, if it is determined at center 10 that the content received from vehicle 100 does not satisfy the operating conditions, a plurality of ECUs 110 of vehicle 100 identified by the vehicle ID number as issuance of operation restrictions etc. for vehicle 100 from center 10 are issued. In response to this, a signal for limiting or changing or stopping the control function is transmitted. As a result, the vehicle 100 is normally managed in a timely manner by the center 10 so that its operation status is properly managed, and when an emergency such as theft or abnormality of the vehicle 100 occurs, it is commensurate with that such as operation restrictions. Appropriate measures can be taken immediately.

  Further, the vehicle communication means achieved by the vehicle side communication unit 140, the antenna 141, etc. of the vehicle operation permission control system of the present embodiment includes the position information of the vehicle 100 in the transmission content transmitted from the vehicle 100 to the center 10. It is a waste.

  That is, the position information of the vehicle 100 is included in the transmission content transmitted from the vehicle 100 to the center 10, and as a result, the position information can be added to the operation permission and the operation restriction that the vehicle 100 receives from the center 10. . As a result, since the road on which the vehicle 100 is operating can be identified, the vehicle is subjected to various traffic restrictions such as a vehicle speed limit set on the road, or operation restrictions are performed when the vehicle is stolen, Is identified, the vehicle 100 can be found immediately.
