[Setting of vehicle speed pulse for reference vehicle speed]
FIG. 3 is a characteristic curve diagram showing the relationship between the vehicle speed and the number of vehicle pulses per unit time. Since the vehicle speed pulse is output each time the driving wheels rotate by a predetermined angle, the number of vehicle pulses per unit time increases as the vehicle speed increases, and the vehicle speed and the number of vehicle pulses per unit time are in a proportional relationship. become.
Thus, in this embodiment, the vehicle speed is detected from the vehicle speed pulses input from the vehicle 2 based on the number of vehicle speed pulses at the reference vehicle speed VT. Instead of the number of vehicle pulses per unit time, the vehicle speed may be detected by applying the time interval of vehicle speed pulses. The time interval is called a vehicle speed pulse of the reference vehicle speed, and is denoted by PT. Here, the reference vehicle speed VT is, for example, 60 km/h.

As a result, the controller 4 switches the operation mode to the vehicle speed pulse setting mode by operating the operator provided on the input device 3 or by operating the input section 13 provided on the display unit 5, and sets the reference vehicle speed VT. Receive the setting of the vehicle speed pulse PT.
Further, in this vehicle speed pulse setting mode, the controller 4 sets the vehicle speed pulse input from the vehicle 2 by operating the setting operator provided on the input device 3 as the vehicle speed pulse PT of the reference vehicle speed VT.

However, when the vehicle speed pulse input from the vehicle 2 is set to the vehicle speed pulse PT of the reference vehicle speed VT by operating the setting operator, the vehicle 2 is running at the reference vehicle speed VT at the time the setting operator is operated. becomes necessary.
Therefore, in the display unit 5, the image display section 9 displays the vehicle speed detected by the vehicle speed detection section 10 and detected by the global positioning satellite system in the vehicle speed pulse setting mode.

FIG. 4 is a plan view showing a display screen (vehicle speed pulse setting screen) of the image display unit 9 in the vehicle speed pulse setting mode.
When the operation mode is switched to the vehicle speed pulse setting mode, the display unit 5 switches the display screen of the image display section 9 to the vehicle speed pulse setting screen shown in FIG.
In this vehicle speed pulse setting screen, "SYSTEM SETUP" is displayed to indicate that it is a vehicle speed pulse setting screen, followed by "PULSE" indicating that the setting is compatible with any type of vehicle speed pulse. FREE" is provided. In addition, a "Push" display is provided to prompt a setting operation, a vehicle speed display (at 60 km/h) to be set is provided, and a button display 21 to be operated is provided. Furthermore, the vehicle speed (59) detected by the vehicle speed detector 10 is displayed.

Thus, in this embodiment, while visually confirming the vehicle speed displayed on the vehicle information display device 1, when the vehicle speed reaches the reference vehicle speed (60 km/h in this example), the vehicle speed of the reference vehicle speed VT is set by operating the setting operator. The pulse PT can be set, the vehicle speed pulse of the reference vehicle speed can be set without viewing a plurality of screens, and the vehicle speed pulse PT of the reference vehicle speed VT can be set more easily than before.
