DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS One embodiment of the present invention will be described with reference to FIGS. FIG. 2 is a block diagram of a first embodiment of the present invention, FIG. 2 is an operation flowchart of the embodiment, and FIG. 4 is an operation flowchart of a distance calculation unit of the embodiment.

In FIG. 2, reference numeral 5 denotes an odd trip indicator for displaying odd and trip data, 6 a display driver for displaying data on the odd trip indicator 1, and 3 a display for the odd trip indicator 5. A display on / off switch for inputting whether or not to enter the black panel mode, 7 is a processor, and 8 to 10 are interfaces (I / O).

The CPU 7 has a distance calculation unit 71, a unit distance travel determination unit 72, and a display control unit 73, which are executed by a program. A signal indicating whether the headlight of the vehicle is on or off is input to the I / O 8.

The I / O 9 receives a pulse from a travel sensor that outputs a pulse every time the vehicle travels a unit distance. The calculated odds and trip data are input to the odd trip display 5 from a device (not shown) that calculates the odds and trip data.

First, the operation of the distance calculator 71 will be described with reference to FIG. The operation is performed by interrupt processing, and is performed by I / O 9
It is performed every time a pulse is input. In the processing S11, the distance calculation unit 71 increments the count value of a counter (not shown) by one.

In the process S12, it is determined whether or not the count value of the counter has reached the count value corresponding to 1 km of travel of the vehicle. If the determination result is NO, the process is terminated.
In the case of ES, the process proceeds to S13. That is, the traveling sensor is connected to the transmission of the vehicle, and generates a pulse corresponding to the traveling of the vehicle. Therefore, if the diameter of the tire of the vehicle is determined, it is possible to calculate how many pulses from the speed sensor are output to travel 1 km, and whether or not the number of pulses obtained by this calculation has been reached. Is determined in step S12.

In step S13, the count value of the distance counter (not shown) is incremented by +1 km, the count value of the counter used in step S11 is reset to 0, and the process ends. Next, the operation of the first embodiment will be described with reference to FIG. In the process S1, the display control unit 73 determines whether it is nighttime or daytime. If it is daytime, the process goes to the process S6 and sends the odds and trip data to the display driver 6 via the I / O 10 in an odd trip. An instruction is displayed on the display 5. If it is nighttime, the process proceeds to step S2.

The determination as to whether or not it is nighttime in the process S1 is made based on a signal input via the I / O 8 as to whether or not the headlights of the vehicle are turned on. In the process S2, the display control unit 73 determines whether or not the display on / off switch 3 is turned on. If the switch is on, the process proceeds to the process S6, where the odd and trip of the odd / trip indicator 5 are performed. The display of data is instructed, and if it is off, the process proceeds to step S3.

In step S3, the unit distance travel determination section 72
Determines whether or not the count value of the distance counter of the distance calculation unit 71 described in FIG. 4 has traveled a predetermined distance, for example, 10 km. If the determination result is NO, the process proceeds to step S5, and if YES, Moves to the processing S4.

In the process S4, the display controller 73 controls the I / O
Instruct the display driver 6 via 10 to display odds and trip data for T seconds, for example 10 seconds. That is, when the determination in the process S3 is YES, the display control unit 73 operates the timer for 10 seconds, and instructs the display driver 6 to perform display until the timer reaches 10 seconds.

In step S5, the display control section 73 does not display on the display driver 6, that is, instructs the display to be turned off, shifts to step S1, and repeats steps S1 to S6. In the embodiment, the pulse from the travel sensor is input from the I / O 9 and the travel distance is integrated by the distance calculation unit 71. However, the odd and trip data input to the odd / trip indicator 5 are calculated. The same distance calculation is also performed in the device, and the results of these shipments, that is, the odds and trip data input to the odd / trip indicator 5 may be referred to.
