Description

  The present invention relates to a parking assistance device, a parking assistance method, and a parking assistance program that can greatly reduce a driver's burden in a parking operation.

  In recent years, the spread of private cars has been remarkable, and accompanying this, accidents during parking operations in parking lots and the like have also increased. In other words, accidents such as contact with passersby and other vehicles who do not realize that the vehicle is performing the parking operation, or accidents such as contact with adjacent vehicles because it is difficult to park in the parking frame. It is increasing. Therefore, conventionally, various proposals have been made to reduce the burden on the driver in such parking operation.

For example, Patent Literature 1 shows a parking assistance device that can determine whether or not parking is possible before a parking operation, and Patent Literature 2 uses a navigation device to enter a region where a vehicle has entered. Accordingly, a technique for controlling the light distribution of a vehicle light is shown.

  By the way, recently, from the viewpoint of preventing accidents in a parking lot, an act of turning on a hazard lamp when performing a parking operation is becoming common. In other words, when the driver enters the parking lot and determines the parking position, the hazard lamp is turned on by operating the hazard lamp switch, etc. to inform other vehicles that the vehicle will perform the parking operation. It is. This makes it possible to appeal to other vehicles that the host vehicle is backing or performing an operation of turning back several times.

  However, in the past, when the vehicle was parked, operations such as checking the surrounding safety, changing gears, turning on the hazard switch, etc. were all performed by the driver himself, so many operations as described above were concentrated on the driver. It was to be requested. In particular, when other vehicles are waiting for the completion of the parking operation of the own vehicle, a plurality of complicated operations is heavy and increases the risk of an accident due to an operation mistake or the like. It was.

  Also, when the surroundings are bright, such as during the day, it is difficult to notice that the hazard lamp remains lit, so it is often the case that the hazard lamp is forgotten to be turned off at the end of the parking operation. As a result, the battery was exhausted and eventually the engine was not started.

Therefore, in the following description, virtual circuit blocks that implement the functions of the present invention and this embodiment are used.

[1-1. Constitution〕
As shown in FIG. 1, the parking assist device of the present embodiment is a current position determination unit 1 that determines whether or not the own vehicle is in the parking lot from the current position information of the own vehicle detected by the navigation device N or the like. From the traveling locus determination unit 2 that determines whether or not the latest traveling locus detected by the navigation device N or the like is a traveling locus unique to the parking operation, and the gear position information acquired from the vehicle computer C or the like. , A gear position discriminating unit 3 for discriminating the gear state, an ACC discriminating unit 4 for discriminating the state of the ACC switch from accessory switch (hereinafter referred to as ACC switch) information acquired from the vehicle computer C, etc., and a hazard lamp ( The hazard lamp control unit 5 for controlling on / off of the notification means) according to the claims, and the hazard according to the signal sent from the hazard lamp control unit 5 A hazard lamp lighting unit 6 to turn or off the lamp L, and a hazard lamp switch 7 which can be the driver independently turned or off the hazard lamps L.
In addition, the structure of the navigation apparatus N is not specifically limited, What is necessary is just what can acquire the present position information and / or driving | running | working locus | trajectory of the own vehicle.

Moreover, in the parking assistance apparatus of this embodiment, the following two types of determination methods can be used in combination for determining whether or not the own vehicle is in the parking lot.
(1) Collation with the map database This method searches the map database installed in the navigation device from the vehicle position information that can be known by the locator, etc., and as a result, the vehicle position is the parking lot. The presence or absence of the information to show is confirmed. When it is not possible to determine whether or not the vehicle position is in the parking lot by this method, the method (2) can be used.

(2) Estimating from the running trajectory of the vehicle The parking operation is performed by using a unique trajectory different from that when driving on a normal road in the parking lot or at the time of parking operation. Estimated. For example, if the travel locus of the latest vehicle is (a) keeps turning in a certain narrow area, (b) if the vehicle repeats moving forward and backward in a certain narrow area, the own vehicle is parked. It is assumed that it exists in the hall or is about to park.

[1-2. Action)
Details of the processing in the parking assistance device of the present embodiment having the above-described configuration will be described with reference to the flowchart of FIG.

  First, the current position of the own vehicle is detected by collating with a map database or the like provided in the navigation device N (step 201), and the current position determination unit 1 determines whether the own vehicle position based on the map database is in the parking lot. Is determined (step 202). If it is determined in step 202 that the vehicle position is in the parking lot, the process proceeds to step 204.

  On the other hand, if it is determined in step 202 that it is “not in the parking lot” as a result of collation with the map database, the traveling locus discriminating unit 2 determines that the traveling locus of the own vehicle is unique within the parking lot or is equivalent thereto. It is determined whether or not there is (step 203). If it is determined in step 203 that the travel locus of the host vehicle is not unique to the parking lot, the process returns to step 202, assuming that the host vehicle position is not in the parking lot.

  On the other hand, if it is determined in step 203 that the travel locus of the host vehicle is unique to the parking lot, and if it is determined in step 202 that the host vehicle position is in the parking lot, the gear is reverse (reverse). (Step 204), and if it is detected that the gear is put in the back, the hazard lamp control unit 5 outputs a hazard lamp on signal to the hazard lamp lighting unit 6. The hazard lamp is turned on (step 205).

  Thereafter, the process proceeds to step 206 to detect whether or not the ACC switch is turned off. If it is determined in step 204 that the gear is not engaged, the process proceeds directly to step 206 to detect whether or not the ACC switch is turned off. If it is detected in step 206 that the ACC switch is turned off, a hazard lamp off signal is output to turn off the hazard lamp.

[1-3. effect〕
According to the present embodiment as described above, since the hazard switch on / off operation is not required during the parking operation, the burden on the driver is reduced, and the risk of an accident due to an operation error or the like is greatly reduced. .
Further, when it is detected that the ACC switch is turned off thereafter, the hazard lamp is automatically turned off, thereby reducing the burden on the driver and preventing the hazard lamp from being forgotten to be turned off.

[2. Other embodiments]
The present invention is not limited to the above-described embodiment, and the gear state and the traveling locus of the host vehicle may be determined based on GPS, gyroscope, speed pulse, gear state indicator, and the like.
Whether the hazard lamp is actually turned on or off is determined by the “OR” condition between the presence / absence of the hazard lamp ON signal and the operation of the hazard lamp switch 7 by the driver or the like.
Furthermore, as a means for notifying the surroundings that the parking operation is being performed, not only the above-described hazard lamp is turned on, but also a method of generating a warning sound may be used.

It is a functional block diagram which shows the structure of the parking assistance apparatus which concerns on this invention. It is a flowchart which shows the procedure of the process in the parking assistance apparatus which concerns on this invention.
