JP7307672B2 - Driving speed control system for vehicles during traffic congestion - Google Patents

Description

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a vehicle travel speed control system, and more particularly to a vehicle travel speed control system, preferably for easing traffic congestion.

For example, traffic jams occur on highways and other arterial roads due to the effects of lane restrictions during road construction, the effects of vehicles unintentionally slowing down before bridges and tunnels, and the effects of road gradients. There are some sections where traffic congestion is likely to occur, and various techniques have been proposed to alleviate congestion in such sections where congestion is likely to occur (see, for example, Patent Document 1).

In addition, by setting the flashing speed in the direction of travel of a plurality of flashable light emitters (flashing lights) provided along the road to a predetermined speed, the driver of a vehicle traveling on the road can observe the speed of travel. There is also disclosed a technique for making it possible to recognize that the distance exceeds a safe range or that it is in a range that causes congestion (see, for example, Patent Document 2). Furthermore, by applying the technology of setting the flashing speed of such flashing lights to a predetermined speed, a plurality of road guide lights (flashing lights) can be set to sequentially flash according to a predetermined traveling speed. Also disclosed is a technique (see, for example, Patent Document 3, paragraph [0058]) for alleviating traffic congestion by guiding vehicles to pass at an appropriate running speed.

On the other hand, exploitation of the vection effect, known as visually-induced self-kinesthetic sensation, has been investigated as a means of guiding a vehicle traveling on a road to speed up or slow down. The vection effect is a phenomenon in which, for example, a person on a stopped train feels as if his/her own train is moving when the opposite train starts to move. Such a vectoring effect is not felt when the opposite train passes at normal speed because the speed difference is too large. Research has also been conducted that the speed difference at which the effect is easily felt is in the range of, for example, about 10 to 20 km (see, for example, Non-Patent Document 1).

However, in the techniques of Patent Document 2 and Patent Document 3, since the plurality of flashing lights are designed to flash at a predetermined flashing speed, for example, a vehicle in a traffic jam remains in a congested state. If the traveling speed during traffic congestion is changed from moment to moment, simply blinking multiple flashing lights at a predetermined flashing speed will not reflect the actual speed during traffic congestion. As a result, the vectoring effect cannot be sufficiently exhibited. For this reason, for example, even if a vehicle in a traffic jam changes its traveling speed in a traffic jam from moment to moment, the vehicle traveling on the road can increase its speed by fully exhibiting the vection effect. There is a demand for the development of a technology that enables smoother guidance for raising and lowering.

SUMMARY OF THE INVENTION It is an object of the present invention to provide a vehicle travel speed control system that can sufficiently exhibit a vectoring effect and smoothly guide a vehicle traveling on a road to speed up or slow down. and

From the measurement data during traffic congestion, the actual traveling speed during traffic congestion is calculated, and the speed in the range of +10 to 20 km / h from the calculated actual traveling speed during traffic congestion is calculated as the induced speed. The flashing speed control unit controls the flashing speed of the plurality of flashing lights so that the speed calculated by the guide speed calculation unit is the guide speed during traffic congestion, and guides the speed of the vehicle while generating a vectoring effect. Thus, the above object is achieved by providing a travel speed control system for vehicles during traffic jams that can alleviate traffic jams .

From the difference in passing times at points, it is possible to calculate an accurate required time even during traffic congestion. MOVTRA (registered trademark) uses a long-range infrared ranging sensor and installs two sensors for one lane. The traveling speed is calculated from the reaction time difference, or the calculated traveling speed is multiplied by the infrared reaction time to calculate the length of the vehicle.

For example, the data for calculating the actual traveling speed of a vehicle traveling on a road in traffic congestion, which is acquired by the speed measurement data acquisition unit 11, is preferably sent to the system server 14 and stored in the storage unit, and the system Based on these data, the server 14 calculates the actual traveling speed, which is the actual speed of the vehicle during traffic congestion, and transmits it to the guided speed calculation unit 12 every 5 minutes as a representative speed for 15 minutes, for example.
