Can be defined by

Recommended Speed (ℓ 2 / t 2 ) = [(Vmax) / (ℓ 1 + ℓ 2- (t 1 × Vmax)) × ℓ 2 ]

Here, Vmax is the prescribed speed, ℓ 1 is the distance from the moment to enter the segment control area 110 to the current driving position, ℓ 2 is the remaining distance, t 1 is the current driving from the moment to enter the segment control area 110 Indicate the travel time taken by the vehicle to the location.

Looking at the process of deriving the recommended speed (ℓ 2 / t 2 ) is as follows.

The recommended speed can be calculated as follows because the average speed in the intermittent zone is the same or slower than the specified speed.

Specified speed (Vmax) = (ℓ 1 + ℓ 2 ) / (t 1 + t 2 )

(t 1 + t 2 ) = (ℓ 1 + ℓ 2 ) / Vmax

t 2 = (ℓ 1 + ℓ 2 ) / Vmax-t 1

ℓ 2 / t 2 = (Vmax) / (ℓ 1 + ℓ 2- (t 1 × Vmax)) × ℓ 2

Where (ℓ 2 / t 2 ) is the speed of the vehicle driving the remaining distance, and the speed of the vehicle driving the remaining distance is (Vmax) / (ℓ 1 + ℓ 2- (t 1 × Vmax)) × ℓ It should be less than 2 .

For example, if the total distance of the section control area 110 is 6Km, the specified speed is 100Km / h, and the driving vehicle runs at a distance of 2Km per hour from the start point of the section control area at 120Km, the recommended speed is as follows. Can be given together.

The driving speed of the 2km section is 1 minute, i.e. 1/60 hours, so the recommended speed is 100km / h / (6km-(1/60) h × 100km / h) × 4km, so 92.3km / h will be.

In this embodiment, the recommended speed is such that the average speed with which the vehicle runs from the start point to the end point of the section control area 110 is the same as the speed defined in the section control area 100. Alternatively, it is of course possible to recommend a predetermined speed less than the speed prescribed in the section control area 100.

The section driving information calculated by the controller 30 may be displayed by the display unit 40 as a voice and / or an image as described above.

In addition, the section driving information may include information on the difference between the average speed of the vehicle and the average speed of the vehicle calculated by the above method and the prescribed speed stored in the storage unit 20. For example, when the average speed of the vehicle is 110Km / h and the prescribed speed is 100Km / h, this means that the difference information is 10Km / h.

In addition, the section driving information may include the remaining distance from the current position of the vehicle to the end point of the section control area (110). Since the remaining distance means the distance obtained by subtracting the distance traveled by the vehicle in operation from the entire length of the intermittent section area, referring to FIG. 2, ℓ-ℓ 1 = ℓ 2 becomes the remaining distance.

And the section driving information, the speed of the vehicle from the moment it enters the section enforcement area 110 to the current driving position, that is, the average speed and the recommended speed calculated based on the prescribed speed in the section enforcement area 110 It is possible to be included.
