DESCRIPTION:
BRIEF SUMMARY
BACKGROUND OF THE INVENTION
1. Field of the Invention
The present invention relates to an on-vehicle data processing system and particularly to such a system which can indicate the running and stop mode images on an on-vehicle display.
2. Prior Art
At present, display devices such as TV and other monitors are frequently mounted on vehicles. It is expected that on-vehicle display devices increasingly spread since their size and manufacturing cost will be reduced with advancement of the technology.
However, the on-vehicle display devices of the prior art were only used to indicate the present position of a vehicle through a navigation system or to display television scenes through a TV receiver. They were rarely used in the other applications.
With the navigation system, the on-vehicle display devices will not frequently be used as the vehicles are daily running. Television scenes will not be viewed by the drivers as the vehicles are running. In practice, therefore, the on-vehicle display devices were rarely used.
SUMMARY OF THE INVENTION
In view of the problems in the prior art, an object of the present invention is to provide an on-vehicle data processing system which displays data on a vehicle on an on-vehicle display device. The data to be displayed when the vehicle is running are different from the data to be displayed when the vehicle is not running, so that the on-vehicle display device can be effectively used.
To this end, the present invention provides a on-vehicle data processing system comprising mode setting means responsive to the present speed of a vehicle for selecting and setting one of running and stop modes and display data processing means for computing running mode images indicating running states of the vehicle when the running mode is selected and set and for computing stop mode images indicating detailed various vehicle information when the stop mode is selected and set, thereby causing the running or stop mode images to be displayed on an on-vehicle display device.
Thus, the on-vehicle data processing system of the present invention can be responsive to the present speed of the vehicle for selecting and setting one of the running and stop modes. In the running mode, the running mode images indicating running states of the vehicle are computed and displayed on the on-vehicle display device. In the stop mode, the stop mode images indicating detailed vehicle information are computed and displayed on the on-vehicle display device.
In such a manner, the on-vehicle data processing system of the present invention can preferentially cause the running mode images more easily viewed by the driver to display on the on-vehicle display device when the vehicle running mode is selected and set and can preferentially cause the stop mode images to indicate the contents of the information to display on the on-vehicle display device when the stop mode is selected and set. Thus, the driver can obtain various vehicle information from the on-vehicle display device.
In one preferred embodiment of the present invention, the on-vehicle data processing system may comprise control means for selecting any one of items for the running or stop modes, wherein the display data processing means computes the running or stop mode images representing a selected item.
Thus, the control means can be used to select any one of the items for the running and stop modes. For example, the items indicating the running states of the vehicle include speed, fuel consumption, torque, acceleration and others. Any one of these running mode items can be selected and displayed on the on-vehicle display device in real time. When the item of torque is selected, for example, variations in torque can be indicated on the on-vehicle display device in real time.
The details of the vehicle information may include various items indicating vehicle maintenance information, travel information and others. Any one of these items can similarly be selected and indicated on the on-vehicle display device.
Thus, the driver can select any necessary ite
