Figure 1 shows an optimal parking location search system according to an embodiment of the present invention.

The passenger recognition unit 110 obtains passenger information using at least one sensor that senses the interior of the vehicle. Occupant information includes the occupant's seating position, body, body type, age, and whether or not a car seat is used.

The parking space recognition unit 120 uses external sensors (ultrasound, lidar, radar, cameras, etc.) of the vehicle to recognize parking lines and search for the positions of pillars in the parking lot.

The parking position selection unit 130 selects the optimal parking position after parking by considering the left/right unloading space, the thickness of surrounding pillars, etc.

The control unit 140 provides guidance to the selected parking location or performs automatic parking at the selected parking location in conjunction with the automatic parking system.

Assuming that there is a driver in the vehicle and a child seated in a car seat behind the driver's seat, when reverse parking is completed, the driver must get out and open the rear door of the driver's seat to drop off the child seated in the car seat. In other words, when parking is completed, it is necessary that the space on the left side of the vehicle is relatively wider than the space on the right side. When parking to the right is encouraged within the parking line, the driver of another vehicle parked on the right must open the driver's door of the other vehicle. Damage may occur due to insufficient space for boarding. Therefore, it is assumed that the first parking candidate space is a space with a wall on the right, the second parking candidate space is a space between already parked vehicles and the vehicle, and the third parking candidate space is a space with a wall on the left. , Right expresses the direction based on the front of the vehicle when parking in reverse). In this case, since the driver must get off and the child seated in the car seat behind the driver's seat, the third parking candidate space is primarily excluded from the parking location selection. In addition, the second parking candidate space, which is expected to not secure sufficient left-side exit space due to the small space between vehicles, is secondarily excluded from the parking location selection, and the first parking candidate space is selected as the optimal parking location. . Additionally, there is a wall on the right side of the first parking candidate space, and since only the driver's door and the rear driver's door need to be opened after parking, a guide is provided to park tilted to the right based on the parking line, or automatic parking is performed.

As another example, assuming that in addition to the driver, an elderly person is riding in the rear passenger seat, it is difficult for the elderly person to get out of the car by opening the car door only partially and holding it with arm strength when reverse parking is completed. Alternatively, there is a risk that an elderly person may open the door wide, resulting in a door locking accident to the vehicle parked on the right. In other words, when parking is completed, the space on the right side needs to be relatively wide, but if parking is forced to the left within the parking line, there may not be enough space for the driver to get out. Therefore, it is assumed that the first parking candidate space is a space with a pillar next to the left rear seat, the second parking candidate space is the space between the already parked vehicle and the vehicle, and the third parking candidate space is a space with a wall on the right. (Left and right expressions are based on the front of the vehicle when parked in reverse). In this case, since the elderly person sitting behind the passenger seat must get off, the third parking candidate space is primarily excluded from the parking location selection, and the space between vehicles is not wide, so sufficient left and right unloading space will not be secured. The expected second parking candidate space is secondarily excluded from the parking location selection, and the first parking candidate space is selected as the optimal parking location. In addition, in the first parking candidate space, a pillar is located next to the rear seat of the driver's seat, and there is no need to open the rear door of the driver's seat, so a guide is provided to park tilted to the left based on the parking line, or automatic parking is performed.

As another example, an electric vehicle charging station is set as the destination in the navigation information, and when the vehicle arrives at the destination, it is encouraged to park so that there is free space on the side where the charging port is located. In other words, parking guidance is provided according to the charging port location, and when the charging port is in the front, front parking is encouraged and guidance is provided.

Figure 2 shows a method for searching for an optimal parking location according to an embodiment of the present invention.

The optimal parking location search method according to an embodiment of the present invention includes checking passenger information (S210), obtaining parking space information (S220), selecting a parking location (S230), and providing a parking guide. or performing automatic parking (S240).

In step S210, occupant information is obtained using at least one sensor that senses the interior of the vehicle. Occupant information includes the occupant's seating position, body, body type, age, and whether or not a car seat is used.

In addition, in step S210, the passenger's physical information (height, weight, body type) is acquired, and the passenger's flexibility information and whether boarding/disembarkation is possible when the door is opened to what extent is obtained by considering previous boarding/disembarkation records. Record or infer.

In step S220, parking lines are recognized using external sensors (ultrasonic waves, lidar, radar, cameras, etc.) of the vehicle, and the positions of pillars in the parking lot are searched.

Additionally, in step S220, the specifications of the parking lot (length, width of parking line, thickness information of pillars, etc.) are recognized or the specifications of the parking lot are acquired through I2V communication.

In step S230, the optimal parking location is selected considering the left and right unloading spaces after parking. At this time, the vehicle's specifications, vehicle's passenger information, preferred parking type information, left/right/rear (e.g., where a child in a car seat is seated in the vehicle, and where the elderly passenger is located in the vehicle) Select a parking location by taking into account whether the vehicle is seated and the required free space (if the trunk is expected to be opened at a supermarket or department store, there may be a wall behind the parking lot, making it difficult to load luggage after the electric trunk is opened).

In step S240, a guide is provided to the selected parking location, or automatic parking is performed at the selected parking location in connection with the automatic parking system.

According to another embodiment of the present invention, the remote forward/backward function is automatically performed in the process of re-boarding to exit the vehicle after a certain time has elapsed after getting off in consideration of user history. For example, assume that there is a driver (adult male), spouse (adult female), and child (child sitting in the car seat behind the passenger seat) who want to get on board after shopping at the supermarket. At this time, if there is a wall at the rear of the parked vehicle and contact is expected to occur when opening the electric trunk, or if it is judged that there is not enough space to load items into the trunk, the driver's smart key is detected approaching and the remote forward function is activated. is automatically performed to advance a certain distance. At this time, whether it is possible to move forward is determined by considering the traffic conditions of pedestrians and other vehicles located nearby. As the vehicle moves forward a certain distance, if there is sufficient space at the rear of the vehicle to open the trunk and load items, the driver places the items in the trunk. As the vehicle moves forward a certain distance, if it is difficult to open the door of the passenger seat or rear passenger seat due to the pillar on the right side of the vehicle, the remote reverse function is automatically performed by loading items into the trunk and closing the trunk. As the car returns to its original parking position, there is sufficient space to open the doors on the passenger seat and the rear passenger seat, allowing the child to ride in the passenger seat and in the car seat behind the passenger seat.
