Abstract

An information center provides a control program which is usable by a vehicle within its effective area. The control program may be transmitted to a vehicle in conjunction with the effective area through a broadcast antenna. According to the detected result of the current location, a control apparatus on a vehicle applies a control program to device control when the current location sites within the effective area. The vehicle can take possession of a control program fits to a region at any places to which it moves and can utilize those. It is possible to substitute an effective period for the effective area.

Claims

1. An on-vehicle device control system comprising:

an information center for transmitting a control program for controlling an on-vehicle device equipped on a vehicle in conjunction with geographical data designating an effective area of said control program; and

a control apparatus equipped on said vehicle for controlling the on-vehicle device in accordance with said control program transmitted from said information center;

wherein

said control apparatus includes positioning means for detecting a current geographical location of the vehicle and applying said control program when the detected current geographical location is within said effective area and memory means for storing said control program until the detected geographical location lies within said effective area.

2. An on-vehicle device control system according to claim 1, wherein said information center transmits said control program and said effective area to said vehicle along with data designating the effective period during which said control program should be applied, and wherein

said control apparatus includes time detecting means and applies said control program when the detected present time is within the effective period.

3. An on-vehicle device control system according to claim 1, wherein said information center transmits said control program through broadcasting means and a broadcast area is configured to encompass said effective area therein.

4. An on-vehicle device control system according to claim 1, wherein said control apparatus comprises a navigation unit for performing route guidance and manages said control program based on the detected current location.

5. An on-vehicle device control system according to claim 4, wherein said navigation unit manages said control program through the use of cartographic data for navigation.

6. An on-vehicle device control system according to claim 1, wherein

said vehicle is a hybrid car,

said on-vehicle device is a motor including an internal combustion engine and an electric motor, and

said control program is a power control program which controls said motor.

7. An on-vehicle device control system according to 1, wherein said on-vehicle device is a navigation unit and said control program is a route computation program for generating a route to be guided.

8. An on-vehicle device control system which controls an on-vehicle device equipped on a vehicle, comprising:

an information center for transmitting a control program to be used for controlling said on-vehicle device to said vehicle in conjunction with data designating the effective period during which said control program should be applied; and

a control apparatus equipped on said vehicle for controlling said on-vehicle device through the use of said control program transmitted from said information center;

wherein

said control apparatus includes time detecting means and applies said control program when the detected present time is within said effective period and memory means for storing said control program until the detected present time is within said effective period.

9. An device control apparatus which is equipped on a vehicle and controls an on-vehicle device comprising:

receiving means for receiving a control program transmitted from the outside of said vehicle and used for controlling said on-vehicle device and data designating the effective area in which said control program should be applied, and

positioning means for detecting current location of said vehicle, wherein

said control apparatus controls said on-vehicle device through applying said control program when the detected current location lies within said effective area and memory means for storing said control program until the detected current location lies within said effective area.

10. A device control apparatus which is equipped on a vehicle and controls an on-vehicle device, said apparatus comprising:

receiving means for receiving a control program transmitted from the outside of said vehicle and used for controlling said on-vehicle device, and data designating the effective period in which said control program should be applied, and

time detecting means to detect present time, wherein

said control apparatus controls said on-vehicle device through applying said control program when the present time is within said effective period and memory means for storing said control program until the detected present time is within said effective period.
