Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a vehicle-mounted television device, and particularly to a vehicle-mounted television device that is installed in a vehicle and displays driving conditions of the vehicle, television images, and the like.

Modern vehicles are equipped with numerous instruments that display driving conditions, such as speedometers, tachometers, oil pressure gauges, and coolant temperature gauges, as well as instruments for controlling indoor air-conditioning equipment, control panels for car stereos, and clocks. has been done. However, such instruments are scattered on the instrument panel in the driver's cab, making it difficult to quickly read the displays on the instruments. Therefore, there is a demand for the various instruments mentioned above to be centrally managed and displayed by a computer.

Conventionally, an in-vehicle television device that displays the television image and driving conditions has been proposed;
Displaying TV images with this device requires a channel display section, which not only increases cost but also increases the size of the device.As a result, a large installation space is required on the instrument panel for installation, and the centralization of the instruments is difficult. It was difficult.

The present invention was devised in view of the above-mentioned conventional problems, and its purpose is to provide a low-cost in-vehicle television device that centralizes the instruments by effectively utilizing the instrument panel surface. It is in.

In order to achieve the above object, the present invention includes a television receiver capable of displaying at least television images and other driving conditions, and a digital clock is provided near the television receiver;
When receiving a television image on the television receiver, the digital clock is used as a channel display for a predetermined period of time at the start of reception and when changing channels.

Hereinafter, preferred embodiments of the present invention will be described based on the drawings.

In FIG. 1, the in-vehicle television apparatus of the present invention has a configuration in which a television receiver 12 is disposed on an instrument panel 10, and a digital clock 14 is attached near the television receiver 12.

The television receiver 12 is capable of displaying at least the television image 16 and the driving conditions of the vehicle, and normally displays the vehicle speed as the driving condition, but can also display the remaining amount of fuel, temperature of cooling water, oil pressure, etc. as appropriate. Necessary information such as engine speed and battery voltage is selected.

The television image 16 and information such as driving conditions are centrally managed by a computer, and although the television image 16 and the driving condition image can be switched using a key or button, the two images may not overlap. It is also possible to display the In that case, for example, the driving conditions may be displayed in one corner of the TV image. The driving conditions can be displayed in either analog or digital format.

A digital clock 14 installed near the television receiver 12 usually displays the time using a liquid crystal, a fluorescent display tube, a light emitting diode, or the like, as shown in FIG.

A characteristic feature of the present invention is that when the television image 16 of the television receiver 12 is received, the time display section 18 of the digital clock 14 is clocked for a predetermined period of time when the reception starts, when changing the channel, or when checking the channel. The channel of the TV being watched is displayed.

The embodiment of the present invention has the above configuration, and its operation will be explained below.

FIG. 3 shows a control flow diagram of the in-vehicle television device according to the present invention. First, when the ignition switch is turned on, the vehicle speed is displayed on the screen of the television receiver 12, and at this time the digital clock is displayed. The time is displayed at 14. This state is maintained continuously unless the TV switch key or other driving condition display switch is operated.

When you press the TV switch key, TV receiver 1
A television image appears on the screen 2, and at this time, the television channel being received is displayed on the display section 18 of the digital clock 14 for only 5 seconds. After 5 seconds have elapsed, the channel display returns to the time display, and this state is maintained.

Next, when the channel search key is pressed or the channel is changed, the tuning circuit built in the television receiver 12 is activated, and the reception channel selection is performed within a predetermined time.
The new television channel that has been changed is displayed on the time display section 18 of No. 4 for only 5 seconds. As in the case described above, the channel display returns to the time display after 5 seconds have elapsed. If the television image 16 is turned off by operating a switch key or button on the television, the vehicle speed will be displayed on the screen of the television receiver 12 again.

As explained above, according to the present invention, the television receiver 12 can display the channel using the digital clock 14 when receiving the television image 16, and the digital clock 14 can display the time and the channel. Since it can be used for both purposes, even though the in-vehicle television device of the present invention is installed in the instrument panel 10, there is no need to prepare a separate installation space for the channel display, and it is possible to mount the conventional driving condition display and digital clock 14. It can be installed within a space, and the various instruments installed on the instrument panel 10 can be centralized, and the cost for installing the device can be reduced.
