Description

[Detailed description of the invention] Industrial application field The present invention is a method for preventing cars leaving a parking lot from colliding with or coming into contact with cars running on the road in front of the parking lot. It is related to the safety equipment of the time.

BACKGROUND ART Conventionally, when cars in a parking lot move forward or backward onto the road, they have relied on a manager or assistant to guide them, especially in areas with poor visibility.

Problems that the invention aims to solve: According to the conventional system as described above, when there is no caretaker or assistant, the driver must rely on the driver's visual observation, and at that time, it is necessary to rely on the driver's visual observation to determine whether the vehicle is within the braking distance or outside the braking distance. Collisions and contact often occurred because it was difficult to confirm whether the

An object of the present invention is to provide a safety device for leaving the vehicle safely even when there is no caretaker or assistant present.

Means for Solving the Problem In order to solve the above-mentioned problems, the safety device for exiting the vehicle according to the present invention is provided with an alarm device at the entrance/exit of the vehicle that instructs the driver to stop exiting the vehicle, and an operation to disable the alarm device. A detection device is provided for detecting the traveling speed of the vehicle on the road in front of the vehicle entrance and exit, and when the detection device is connected to the detection device and the detected value signal from the detection device is within the range of the braking distance. The actuating device is provided with a processing device that issues an actuation signal for instructing release.

According to the configuration of the present invention, when a vehicle about to leave the vehicle is instructed by the warning device to stop, the detection device detects the traveling speed of the vehicle on the road. When the detection device does not detect a running vehicle, or when it detects a vehicle and sends a detection value signal to the processing device, but the signal is within the braking distance, the processing device issues an activation instruction to the actuation device to release the vehicle. A signal is issued, and the warning device that instructs the driver to stop starting the vehicle can be released and moved to a state where the driver can start the vehicle.

Embodiment An embodiment of the present invention will be described below based on the drawings. 1 is a multi-storey parking lot, and 2 is the road 3 where cars enter and exit.
facing. The vehicle entrance/exit 2 is provided with a bar 5 (an example of a warning device for instructing the driver to stop starting the vehicle) which is interlocked with an opening/closing device 4 (an example of an actuating device for releasing a warning device). The bar 5 opens and closes the vehicle entrance 2 by swinging, but it may also be of the up-and-down type. A detection device (such as a radar) 8 for detecting the traveling speed of a vehicle 7 traveling on the road 3 is disposed on the roof of the multi-story parking lot 1 or within an occupied area. A processing device (such as a computer) 10 connected to this detection device 8 is provided. When the detected value signal 11 is within the braking distance range, the opening/closing device 4 is configured to issue an opening signal 12 (operating signal for instructing release). The braking distance is normally set as the distance from the detection point to the vehicle entrance/exit 2 and based on the speed limit, but here, a certain safe distance is taken from the vehicle entrance/exit 2, and the braking distance is set as the distance from this point. Set based on speed limit. The vehicle entrance 2 is provided with a vehicle detection device 14 for detecting the presence of a retrieval vehicle 13 below the bar 5 which is being opened, and the output thereof is given to the opening/closing device 4 as a reset signal 15. Furthermore, the vehicle detection device 14 is located at the vehicle entrance/exit 2.
A vehicle departure detection device 16 is provided on the far side, and the output from this device is sent as an on signal 17 to the opening/closing device 4.
and is given to the safety device 10.

Normally, the bar 5 is open. When the unloading vehicle 13 passes through a predetermined position near the car entrance 2, it is detected by the unloading detection device 16, and the on signal 17 activates the opening/closing device 4 to close the bar 5, and the processing device 10 into an operational state. At this time, the detection device 8
is not detected, or when it is detected and the detection value signal 11 is input to the processing device 10 but within the braking distance range, the processing device 10 issues an opening signal 12 to the opening/closing device 4, bar 5
is opened, and the leaving vehicle 13 can leave the warehouse as it is. Furthermore, when the braking distance is exceeded, the opening signal 12 is not issued from the processing device 10 to the opening/closing device 4, so the bar 5 is
It remains closed in front of 3. bar 5 after that
The opening movement is performed by receiving the opening movement signal 12. The bar 5 opens and the outgoing car 13 moves to the car entrance 2.
Even if the opening signal 12 is no longer received due to the detection of a traveling vehicle 7 while the vehicle is passing through the vehicle, this is reset by the reset signal 15 from the vehicle detection device 14, and the bar 5 does not lower.

In the embodiment, the car entrance 2 of the multi-story parking lot 1 is shown, but this may be the car entrance of a garage in a general household or the car entrance of a building parking lot. Further, although the bar 5 is shown as a warning device, this may be an audio warning, a lamp warning, etc., and in this case, a corresponding activation device is prepared. Furthermore, the detection device 8 is installed at any desired location. In conjunction with the opening of the bar 5, it is also possible to warn pedestrians passing in front of the vehicle entrance 2. This warning can be given by lamp, voice, text display, etc. In addition, in the above description, the bar 5 is closed by the on signal of the exit detection device 16, but this is the on signal detected when the rotary table for changing the direction provided at the back side of the bar 5 is operated. Alternatively, the bar 5 may be moved to close.

Effects of the Invention According to the vehicle exit safety device of the present invention configured as described above, when a vehicle about to exit the garage is instructed to stop exiting by the warning device, the detection device detects the traveling speed of the vehicle on the road. can be detected. When the detection device does not detect a running vehicle, or when the detection device detects a vehicle and sends a detection value signal to the processing device, but the signal is within the braking distance, the processing device issues an activation instruction to the actuation device to release the vehicle. A signal is issued, and the warning device that instructs the driver to stop starting the vehicle can be released and moved to a state where the driver can start the vehicle. This means that when the detection device detects a vehicle traveling at a speed exceeding the braking distance range, the warning device can instruct the vehicle to stop exiting. As a result, it is possible to prevent a collision or contact with a traveling vehicle, and it is also possible to safely exit the vehicle even when there is no caretaker or assistant present.
