Abstract

A travel mode setting device for a hybrid car capable of ensuring the security against car theft and convenience when the car is lent to the third party. The hybrid car has travel drive sources and selectively uses one of them and can travel in one of travel modes. Authenticating means separately authenticate the car user and creates authentication results. Limiting means limits the travel modes to the usable travel modes according to the results of the authentication by the authenticating means.

3. The travel mode setting device for a hybrid vehicle according to claim 1, wherein:

the plurality of travel drive sources include an engine and an electric drive source;

the plurality of travel modes include an electric drive source travel mode, which drives only the electric drive source, and a hybrid travel mode, which drives both of the engine and the electric drive source; and

the specification means allows for only the electric drive source travel mode when at least one of the authentication results of the plurality of authentication means indicates non-establishment of authentication and allows for both the electric drive source travel mode and the hybrid travel mode when every one of the authentication results of the plurality of authentication means indicates establishment of authentication.

4. The travel mode setting device for a hybrid vehicle according to claim 1, wherein:

the plurality of authentication means includes a biometric authentication means for obtaining biometric information from the vehicle user and using the biometric information to authenticate the vehicle user.

5. The travel mode setting device for a hybrid vehicle according to claim 1, wherein:

the hybrid vehicle has a first identification code; and

the plurality of authentication means includes an identification code verification means, which has a second identification code, for determining whether or not the first identification code and the second identification code are the same to authenticate the vehicle user.

6. The travel mode setting device for a hybrid vehicle according to claim 1, wherein:

the hybrid vehicle has a first identification code; and

the plurality of authentication means includes;

a first identification code verification means, which has a second identification code, for determining whether or not the first identification code and the second identification code are the same to authenticate the vehicle user; and

a second identification code verification means, which has a third identification code, for determining whether or not the first identification code and the third identification code are the same to authenticate the vehicle user.

7. The travel mode setting device for a hybrid vehicle according to claim 1, wherein:

the hybrid vehicle includes a portable device formed by a vehicle key, which is usable for starting the hybrid vehicle, and a main body in which the vehicle key is removably retained; and

the plurality of authentication means includes a retainment check means for detecting whether or not the portable device is retained in the main body of the portable device to authenticate the vehicle user.

8. The travel mode setting device for a hybrid vehicle according to claim 1, wherein:

the specification means controls driving of the plurality of travel drive sources so as to limit travel functions of the hybrid vehicle when less than a predetermined number of the authentication results of the plurality of authentication means indicate establishment of authentication.

2. A travel mode setting device for a hybrid vehicle provided with a plurality of travel drive sources and allowed to travel in one of a plurality of travel modes by selectively using the plurality of travel drive sources, the travel mode setting device comprising:

a plurality of authentication means each for authenticating a vehicle user and generating an authentication result;

a management means for managing a plurality of travel schedules related to the plurality of travel modes; and

a specification means for specifying traveling of the hybrid vehicle by selectively setting the plurality of travel schedules in accordance with the authentication results of the plurality of authentication means.

9. The travel mode setting device for a hybrid vehicle according to claim 2, wherein:

the plurality of travel drive sources include an engine and an electric drive source;

the plurality of travel modes include an electric drive source travel mode, which drives only the electric drive source, and a hybrid travel mode, which drives both of the engine and the electric drive source; and

the specification means allows for only the electric drive source travel mode when at least one of the authentication results of the plurality of authentication means indicates non-establishment of authentication and allows for both the electric drive source travel mode and the hybrid travel mode when every one of the authentication results of the plurality of authentication means indicates establishment of authentication.
