Description

  The present invention is used for a vehicle equipped with a vehicle-to-vehicle communication function. In particular, it relates to a technique for ensuring the safety of pedestrians.

  Vehicle-to-vehicle communication systems that allow vehicles to transmit and receive various types of information are being put into practical use. The inter-vehicle communication system can transmit the traveling information of the own vehicle to the surroundings and receive the information of other vehicles. When this inter-vehicle communication system is put into practical use, it is possible to prevent a collision accident or a rear-end collision on a highway that occurs when passing an intersection or changing a course. In addition, when an emergency vehicle such as a police or a fire department approaches, it is possible to issue an alarm for clearing the course (see, for example, Non-Patent Document 1).

  It is expected to prevent collisions between vehicles or rear-end collisions by using a vehicle-to-vehicle communication system, but if a vehicle-to-person communication accident can also be prevented by using a vehicle-to-vehicle communication system, desirable.

  However, looking at the methods of using the vehicle-to-vehicle communication system that is currently being put into practical use, there is no mention of a method of use for dealing with a vehicle-to-person contact accident.

  The present invention has been made in such a background, and an object of the present invention is to provide a pop-out alarm device that can use a vehicle-to-vehicle communication system for avoiding a contact accident between a vehicle and a person.

  The present invention is a pop-out warning device, which is provided on both sides of the front end of the vehicle, detects the approach of the object, and is provided on at least one side of the rear end of the vehicle, and detects the approach of the object. And a means for transmitting information to other vehicles. The first sensor is a sidewalk sensor when parked on the road, and the second and third sensors are parked on the road. When the sensor is on the roadway side, the second sensor detects the approach of the object within a predetermined time after the first sensor detects the approach of the object, and the third sensor When an approach of an object is detected, there is provided means for transmitting information for calling attention to another vehicle by means for transmitting information to the other vehicle.

  That is, when a pedestrian tries to cross the front of the vehicle parked on the road from the sidewalk toward the roadway, first, the approach of the pedestrian is detected by the first sensor. At this point, it cannot yet be determined that the pedestrian is attempting a dangerous act. Subsequently, when the pedestrian is detected by the second sensor within a predetermined time, it is determined that the pedestrian is about to perform a dangerous act.

  For example, if the predetermined time is set to a very short time, it can be understood that the pedestrian is moving at high speed between the first sensor and the second sensor. It can be judged. On the other hand, if the time from when the pedestrian is detected by the first sensor to when it is detected by the second sensor exceeds the predetermined time, the pedestrian is detected by the first sensor and the second sensor. It can be determined that this is an action with a low risk.

  Furthermore, even if it is determined that it is a dangerous jumping out action, if there is no other vehicle approaching, it is unlikely that the action will lead to an accident, so the third sensor monitors the approach information of the other vehicle, When a pedestrian is about to perform a dangerous jump-out action, and when another vehicle is approaching, information for calling attention to the other vehicle is transmitted using the inter-vehicle communication system.

  In addition, it is possible to provide a means for alerting a person together with the information transmission of the alerting to the other vehicle by the means for transmitting the alerting information.

  Thereby, since attention can be drawn also to the pedestrian who is going to perform dangerous jumping out action, both vehicles and a person can pay attention mutually, and it is useful on ensuring safety.

  In addition, when the approach of the object by the first sensor is used as a trigger, the second or third sensor or the means for transmitting information for alerting the other vehicle or the means for alerting the person is turned on. Means can be provided.

  In vehicles when parked on the road, the engine is often stopped, and it is necessary to keep the battery power consumption as low as possible. In practice, since the first sensor detects the object and then the second and third sensors detect the object, the first sensor detects the object and the second and third sensors and There is no problem even if other related functions are powered on. Therefore, in order to suppress the power consumption of the battery, it is useful to turn on the powers of the second and third sensors and other related functions by using the approach detection of the object by the first sensor as a trigger.

  According to the present invention, the inter-vehicle communication system can be used for avoiding a contact accident between a vehicle and a person.

  A pop-out alarm device according to an embodiment of the present invention will be described with reference to FIGS. FIG. 1 is a block diagram of the pop-out alarm device of this embodiment. FIG. 2 is a traffic situation diagram for explaining the operation of the pop-out alarm device of this embodiment. FIG. 3 is a flowchart showing the operation of the pop-out alarm device of this embodiment.

  As shown in FIG. 1, the pop-out alarm device of the present embodiment is provided on both sides of the front end of the vehicle, is provided with sensors 1 and 2 for detecting the approach of the object, and is provided on at least one side of the rear end of the vehicle. Sensor 3 and a vehicle information transmitting unit 7 for transmitting information to other vehicles. Sensor 1 is a sensor on the sidewalk when parked on the road, and sensors 2 and 3 are roadways when parked on the road. When the sensor 1 detects the approach of the object within a predetermined time after the sensor 1 detects the approach of the object, and the sensor 3 detects the approach of the object, the vehicle information The transmission unit 7 includes means for transmitting information for calling attention to other vehicles.

  Moreover, the alarm issuing part 8 which calls attention to a person is provided with the information transmission of the warning to the said other vehicle by the means to transmit the information which calls the said attention.

  In addition, a battery saving unit 9 for turning on the power of the sensor 2 or 3, the own vehicle information transmission unit 7, or the alarm issuing unit 8 using the detection of the approach of a person by the sensor 1 as a trigger is provided.

  Next, the operation of the pop-out alarm device of the present embodiment will be described with reference to FIGS. As shown in FIG. 3, the parked vehicle 10 is in a parked state and monitors the detection status of the sensor 1 even when the engine is stopped (S1). Here, as shown in FIG. 2, when the pedestrian 20 tries to cross the parked vehicle 10, the sensor 1 detects the approach of the pedestrian 20 (S2). The detection signal of the sensor 1 is input to the information collecting unit 6, and the information collecting unit 6 measures the elapsed time from the time when the sensor 1 detects the approach of the pedestrian 20 and starts monitoring by the sensor 2 (S3). ).

  At this time, until the sensor 1 detects the approach of the pedestrian 20, a voltage is applied to the sensors 2 and 3, the other vehicle information receiving unit 5, the information collecting unit 6, the own vehicle information transmitting unit 7, and the alarm issuing unit 8. The sensors 2, 3 and their associated functions are completely out of service. At this time, the battery saving unit 9 consumes the minimum standby power necessary for detecting the detection signal of the sensor 1. When the battery saving unit 9 detects that the sensor 1 has detected the approach of the pedestrian 20, a voltage is applied to the sensors 2, 3 and their related functions, whereby the sensors 2, 3 and their related functions are activated. .

  Subsequently, the sensor 2 detects the approach of the pedestrian 20 (S4). At this time, the time from when the sensor 1 detects the approach of the pedestrian 20 until the sensor 2 detects the approach of the pedestrian 20 is predetermined. It is within time (S5), and when the approach of another vehicle is detected based on the detection signal of the sensor 3 (S6), the information collecting unit 6 is directed to the own vehicle information transmitting unit 7 and the alarm issuing unit 8. An instruction is issued to issue an alarm (S7).

  This warning is issued from the own vehicle information transmission unit 7 to other vehicles approaching using the inter-vehicle communication function. In addition, the warning issuing unit 8 also performs the pedestrian 20 by sounding a horn, blinking a lamp, or sound signal.

  In addition, as in the case of on-street parking on a one-way street, the sidewalk is on the right side with respect to the forward direction of the parked vehicle 10 and the other vehicle passes through the left side of the parked vehicle 10 as described above. The roles of sensors 1 and 2 are reversed, and the roles of sensors 3 and 4 are also reversed.

  As described above, the information collecting unit 6 can be provided with means for automatically determining whether the sidewalk is on the left or right side of the vehicle parked on the road. One embodiment will be described with reference to FIGS. 4 and 5. FIG. FIG. 4 is a diagram showing a parked vehicle on a one-way road, and on the one-way road, the road can be parked on either the left or right side of the road. FIG. 5 is a diagram for explaining the automatic roadway detection function.

  In the situation shown in FIG. 5, the sensors 1 and 4 or the sensors 2 and 3 adjust the sensitivity so that both the sensors 1 and 4 or the sensors 2 and 3 can detect the passing vehicle when the other vehicle passes by the side. Keep it. A portion surrounded by a broken line in FIG. 5 indicates a detectable region of the sensor. In this way, although there is a slight time lag, it is possible to detect a traveling vehicle in which both the sensors 1 and 4 or the sensors 2 and 3 pass right next to the own vehicle at almost the same timing.

  Therefore, if both sensors 1 and 4 or sensors 2 and 3 frequently detect the approach of an object at almost the same timing, it can be determined that the side where the sensor is installed is the roadway side.

  On the other hand, since the sensors 1 and 4 or the sensors 2 and 3 on the sidewalk side only detect the approach of individual pedestrians, both sensors detect the approach of the object at almost the same timing. Is very small compared to the roadway side. Therefore, it can be determined that the side where the sensor is installed is the sidewalk side.

  In this way, it is automatically determined whether the left or right side of the vehicle parked on the road is the sidewalk side, and only one sensor on the sidewalk side and at the front end of the vehicle is operated at all times. Can keep the power consumption in a vehicle parked on the road very low by stopping the vehicle.

  Further, since the pop-out alarm device of the present embodiment desirably operates even when the driver is away from the vehicle, only the sensor 1 can be detected even when the key switch is removed. The battery saving unit 9 turns on the power of the sensors 2 and 3 and other related functions using the detection of the approach of the object by the sensor 1 as a trigger.

  In addition, in order to avoid the fact that the sensor 1 is in a detectable state despite parking in the garage instead of parking on the road, it is predetermined after the key switch is removed in order to avoid consuming power. After the elapse of time (for example, several hours), the sensor 1 and the battery saving unit 9 are turned off. Alternatively, the power switch for the sensor 1 and the battery saving unit 9 is provided separately from the key switch, and the driver turns off the power source for the sensor 1 and the battery saving unit 9 when parking in the garage.

  According to the present invention, since the inter-vehicle communication system can be used for avoiding a contact accident between a vehicle and a person, it can contribute to the promotion of traffic safety.
