DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a vehicle safety passage system, and more particularly, to a vehicle safety passage system that stops a vehicle based on a speed of the vehicle at an opening / closing gate of a parking lot and a distance from the opening / closing gate.

[0002]

2. Description of the Related Art Conventionally, as this kind of vehicle safe passing system, there is known a system disclosed in Japanese Patent Application Laid-Open No. Hei 6-290399. The vehicle safety passage system disclosed in this publication installs a magnetic marker at a location having a predetermined distance from a crossroads on a road, and when the vehicle approaches the crossroads and reads this magnetic marker, it is mounted on the vehicle. The activated braking control means is activated to generate a primary warning and notify the driver of the approach of the crossroads. Then, a deceleration pattern such that the speed of the vehicle becomes zero at the crossroad is calculated from the distance from the magnetic marker to the crossroad and the speed of the vehicle at that time, and the vehicle is automatically braked in accordance with the deceleration pattern. .

[0003]

In the above-described conventional vehicle safety passage system, only the braking method is mentioned for each of the traveling patterns of the vehicle on the road. There was a problem that no consideration was given to the braking method.

[0004] The present invention has been made in view of the above problems, and an object of the present invention is to provide a vehicle safety passage system capable of safely stopping a vehicle at an opening / closing gate for entering / leaving a parking lot. In addition, in this specification, "parking lot" is not limited to a facility that simply parks the vehicle, but a vehicle such as a cleaning factory that measures the amount of garbage brought in or a weighing station that measures the load of cargo. It is a general term for various facilities that control the entrance and exit of a building using a circuit breaker.

[0005]

In order to achieve the above object, the invention according to claim 1 comprises an opening / closing gate for controlling opening / closing of a gate in a parking lot and managing entrance / exit of the parking lot. A vehicle stopping means for reducing the speed of the vehicle entering the opening / closing gate and stopping the traveling to enter and exit the parking lot, and a vehicle state monitoring means for detecting the traveling speed of the vehicle and the distance from the opening / closing gate; And vehicle stop control means for controlling the vehicle stop means so that the vehicle stops at the open / close gate based on the speed and distance detected by the vehicle state monitoring means.

[0006] In the invention according to claim 1 configured as described above, for a vehicle entering an opening / closing gate to enter / exit a parking lot, the vehicle state monitoring means determines the traveling speed of the vehicle and the opening / closing speed.

In the invention according to claim 5 configured as described above, the stop control for the vehicle stopping means is released when the opening / closing gate is securely opened and the vehicle can pass safely. The vehicle does not start when the opening / closing gate is closed due to an erroneous operation by the driver or the like.

According to a sixth aspect of the present invention, in the vehicle safety passage system according to any one of the first to fifth aspects, the opening and closing gate is operated by a driver of the vehicle at a predetermined operation at the opening and closing gate. Is performed, the gate is opened.

According to the sixth aspect of the present invention, when the deceleration stop control of the vehicle stop control means in the vehicle stop means of the vehicle stopped at the open / close gate is completed, the open / close gate performs passage management. Instruct the driver of the vehicle to carry out predetermined operations such as passing a parking card and paying a parking fee.When this operation is completed, the driver opens the opening / closing gate and enters the vehicle by operating the driver. Delivery is performed.

Thus, the vehicle stop control according to the vehicle state detected by the vehicle state monitoring means can be automatically executed by the vehicle stop means and the vehicle stop control means. However, basically, the driver of the vehicle should operate the brake to stop the vehicle. Therefore, the invention according to claim 7 is an example of a preferred configuration of the vehicle state monitoring means for notifying a driver who has approached the opening / closing gate but has not grasped the situation, of the approach. The vehicle safety passing system according to any one of claims 1 to 6, wherein the vehicle state monitoring means determines that the traveling speed of the vehicle is equal to or higher than a predetermined speed according to a distance from the vehicle stop position. And a warning notifying unit that notifies a warning to the driver of the vehicle to brake the vehicle.

[0019] In the invention according to claim 7 configured as described above, when the warning notifying means determines that the traveling speed of the vehicle is equal to or higher than a predetermined speed corresponding to the distance to the opening / closing gate, the warning operation of the vehicle is performed. Alerts the driver to brake the vehicle. Here, the warning notification means only needs to be able to recognize the warning by the driver of the vehicle and to urge the vehicle to brake. Therefore, a warning may be generated by voice to notify the driver, or the driver may visually recognize the warning using a lamp or the like.
