Abstract

A navigation apparatus is connected through a LAN to a master ECU which outputs a vehicle ID signal including type information showing a type of a vehicle, and obtains the type information from the master ECU. The navigation apparatus stores a map describing specifications such as functions assigned to the steering switches which are sorted by the vehicle type, and sets an operating condition according to the specification corresponding to the obtained type information. For this reason, the navigation apparatus does not need modifying in mounting on the vehicles of plural types.

Claims

1. An on-vehicle device control system comprising:

output means for storing at least type information showing a type of a vehicle and outputting the type information at a predetermined timing;

an on-vehicle device which stores plural specifications to be set in each type of vehicles; and

network means connected to said output means and said on-vehicle device for transmitting the type information outputted from said output means to said on-vehicle device,

wherein said on-vehicle device extracts the specification corresponding to the type information at a time of obtaining the type information outputted from said output means, and sets an operating condition according to the specification.

2. The on-vehicle device control system according to claim 1, wherein said on-vehicle device comprises operating means including a plurality of switches for instructing to carry out functions assigned thereto, and said on-vehicle device stores functions to be assigned to the plurality of switches as the specifications to be set in each type of the vehicles, extracts the functions to be carried out in the vehicle of the type corresponding to the type information, and assigns the extracted functions to the plurality of switches.

3. The on-vehicle device control system according to claim 2, wherein the plurality of switches is installed in a steering wheel.

4. The on-vehicle device control system according to claim 1, wherein said output means outputs the type information every time the vehicle starts.

5. The on-vehicle device control system according to claim 4, wherein said on-vehicle device sets the operating condition according to a predetermined default data, if it can not obtain the type information from said output means when the vehicle starts.

6. The on-vehicle device control system according to claim 4, wherein said on-vehicle device stores the operating condition having been set, and starts its operation with the stored operating condition when the type information can not be obtained from said output means when the vehicle starts.

7. The on-vehicle device control system according to claim 1, wherein said on-vehicle device halts its operation if the type information outputted from said output means does not correspond to any type of the vehicles stored in said on-vehicle device.

8. The on-vehicle device control system according to claim 1, wherein said output means outputs unique information of the vehicle along with the type information, and said on-vehicle device stores the unique information and halts its operation if a newly obtained unique information is different from the stored unique information.
