First Claim
1. An on-vehicle data processing system that processes data while an engine is running based on a present-speed of a vehicle detected by a detector, comprising:
- mode setting means responsive to the present speed of the vehicle for selecting and setting one of running and stop modes, the stop mode being active while the engine is running;
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 various vehicle information when the stop mode is selected and set; and
an on-vehicle display device for displaying the running or stop mode image computed by said display data processing means.

Abstract
An on-vehicle data processing system is provided which can cause the vehicle information to be displayed on a display device 10. The on-vehicle data processing system has a mode setting unit 32 for setting the running and stop modes and a data processing unit 34 for computing the mode images. The data processing unit 34 computes the running mode images representing the running states of the vehicle in real time while in the running mode and the stop mode images representing the details of the vehicle information while in the stop mode. Thus, the running mode images, more easily viewed by the driver, can be displayed on the display device in the running mode while the stop mode images, preferentially displaying the contents of the vehicle information, can be displayed on the display device in the stop mode.
