1. A vehicle security system comprising:
- a driving-device start unit that is portable, includes an ID code, and capable of starting, by transmitting an ID code, a driving device of a vehicle that is prohibited from being started;
an ID-code reception unit that receives an ID code from the driving-device start unit;
a base station that transmits a prohibition instruction for requiring a start prohibition that prohibits the driving device from being started;
an instruction reception unit that receives the prohibition instruction transmitted by the base station; and
a control unit that executes the start prohibition based on the prohibition instruction received by the instruction reception unit and releases the start prohibition so as to enable the driving device to be started, based on the ID code received by the ID-code reception unit, wherein, when the base station transmits the prohibition instruction, the base station transmits a given ID code for releasing the start prohibition, and wherein, when the instruction reception unit receives the prohibition instruction and the given ID code transmitted by the base station, the control unit prohibits the driving device being started by other than a driving-device start unit having the given ID code.

Abstract
When transmitting an instruction for activating an immobilizer function to a subject vehicle, a base station also transmits a given ID code for releasing the immobilizer function. An immobilizer ECU that receives the instruction and the given ID code, prohibits an engine from being started by other than a key having the given ID code. Therefore, a regular user alone, who owns a key having the given ID code, can start the engine.

1. A vehicle security system comprising:
-
a driving-device start unit that is portable, includes an ID code, and capable of starting, by transmitting an ID code, a driving device of a vehicle that is prohibited from being started;
an ID-code reception unit that receives an ID code from the driving-device start unit;
a base station that transmits a prohibition instruction for requiring a start prohibition that prohibits the driving device from being started;
an instruction reception unit that receives the prohibition instruction transmitted by the base station; and
a control unit that executes the start prohibition based on the prohibition instruction received by the instruction reception unit and releases the start prohibition so as to enable the driving device to be started, based on the ID code received by the ID-code reception unit, wherein, when the base station transmits the prohibition instruction, the base station transmits a given ID code for releasing the start prohibition, and wherein, when the instruction reception unit receives the prohibition instruction and the given ID code transmitted by the base station, the control unit prohibits the driving device being started by other than a driving-device start unit having the given ID code.

2. A vehicle security system comprising:
-
a driving-device start unit that is portable, includes an ID code, and capable of starting, by transmitting an ID code, a driving device of a vehicle that is prohibited from being started;
an ID-code reception unit that receives an ID code from the driving-device start unit;
a base station that transmits a prohibition instruction for requiring a start prohibition that prohibits the driving device from being started;
an instruction reception unit that receives the prohibition instruction transmitted by the base station; and
a control unit that executes the start prohibition based on the prohibition instruction received by the instruction reception unit and releases the start prohibition so as to enable the driving device to be started, based on the ID code received by the ID-code reception unit, wherein the control unit includes a storage unit that stores al least two ID codes, wherein the driving device is allowed to be started only by a driving-device start unit that includes at least one of the stored ID codes, wherein, when the base station transmits the prohibition instruction, the base station transmits a given signal for designating, of the stored ID codes, a given ID code as an ID code that is capable of releasing the start prohibition, and wherein, when the instruction reception unit receives the prohibition instruction and the given signal transmitted by the base station, the control unit prohibits the driving device from being started by other than a driving-device start unit having the given ID code.

3. A vehicle security system comprising:
-
a driving-device start unit that is portable, includes an ID code, and capable of starting, by transmitting an ID code, a driving device of a vehicle that is prohibited from being started;
an ID-code reception unit that receives an ID code from the driving-device start unit;
a base station that transmits a prohibition instruction for requiring a start prohibition that prohibits the driving device from being started;
an instruction reception unit that receives the prohibition instruction transmitted by the base station; and
a control unit that executes the start prohibition based on the prohibition instruction received by the instruction reception unit and releases the start prohibition so as to enable the driving device to be started, based on the ID code received by the ID-code reception unit, wherein the control unit includes a storage unit that stores al least two ID codes, wherein the driving device is allowed to be started only by a driving-device start unit that includes at least one of the stored ID codes, wherein, when the base station transmits the prohibition instruction, the base station transmits a given signal for designating, of the stored ID codes, a given ID code as an ID code that is incapable of releasing the start prohibition, and wherein, when the instruction reception unit receives the prohibition instruction and the given signal transmitted by the base station, the control unit prohibits the driving device from being started by a driving-device start unit having the given ID code.

4. A vehicle security system comprising:
-
a driving-device start unit that is portable, includes an ID code, and capable of starting, by transmitting an ID code, a driving device of a vehicle that is prohibited from being started;
an ID-code reception unit that receives an ID code from the driving-device start unit;
a base station that transmits a prohibition instruction for requiring a start prohibition that prohibits the driving device from being started;
