Abstract

A vehicle information provision device comprises an on-board device having a device unit with a display unit that displays each type of vehicle status to a user, and a first control means that operates the display unit; and a communications unit that communicates between the device unit and the external device that outputs external information about the vehicle to the device unit. The communications unit is configured so as to be connectable to the device unit via an attachment/detachment means, and outputs to the device unit signals including at least either a video signal or an audio signal, as the external information for the vehicle, when the device unit is connected to the communications unit via the attachment/detachment means.

Claims

1. A vehicle information provision device comprising:

an on-board device including a device unit including a display unit that displays various states of a vehicle as vehicle status information to a user and first control means that operates the display unit; and

a communications unit that communicates between the device unit and an external device that outputs external information for the vehicle to the device unit, wherein

the communications unit is configured to be connectable to the device unit through attachment/detachment means, and outputs a signal including at least either a video signal or an audio signal as the external information for the vehicle to the device unit, when the device unit is connected to the communications unit through the attachment/detachment means, the external device includes at least two external devices having communication interfaces which are different from each other,

when the communications unit is connected to one external device out of the at least two external devices, the communications unit includes at least two interface units, at least two decoders provided so as to correspond to the at least two interface units, and a selection unit that selects an output from outputs of the at least two decoders, and

a control unit provided in the communications unit controls the selection unit, depending on one connected external device.

2. The vehicle information provision device according to claim 1, wherein

the display unit has a first display region displaying a predetermined type of information out of the vehicle status information and a second display region displaying another type of information out of the vehicle status information, which is different from the predetermined type of information,

when the first control means is connected to the communications unit through the attachment/detachment means, the first control means executes a first display mode for displaying the vehicle status information on the display unit and a second display mode for displaying the vehicle status information and the external information for the vehicle on the display unit, and

when the first control means executes the second display mode, the first control means operates the display unit so as to display the external information for the vehicle in the second display region.

3. The vehicle information provision device according to claim 2, wherein

during the execution of the second display mode, the first control means operates the display unit so as to display operation information associated with the operation of the external device in the second display region.

4. The vehicle information provision device according to claim 1, wherein

if detecting operation information associated with an operation of the external device, output from a predetermined operation means, by the user operating the operation means, the first control means outputs the operation information to second control means provided in the external device through the communications unit, and

the second control means operates the external device based on the operation information.

5. The vehicle information provision device according to claim 4, wherein

the operation means is configured to perform at least either an operation of the device unit or an operation of the external device.

6. The vehicle information provision device according to claim 1, further comprising a sound-emitting body drive circuit connected between the device unit and a sound-emitting body, the sound-emitting body drive circuit including an amplifier and being configured to drive the sound-emitting body based on a sound signal from the communications unit.

7. The vehicle information provision device according to claim 1, wherein

the control unit provided in the communications unit receives the vehicle status information through the device unit and the attachment/detachment means, and outputs the received vehicle status information to the second control means provided in the external device.
