As shown, the parking follow-up control system according to the present embodiment may include an event detection unit 100 and a smart key control unit 200 that controls the smart key 300.

The event detection unit 100 may include a vehicle movement detection unit 110 and an image pickup module 120 to detect events that may occur after the vehicle is parked, in particular an emergency or an emergency situation. You can. The event detection unit 100 may include a plurality of individual detection components as in the present embodiment, and may further include a control module that integrates and controls contents detected by the individual detection components.

The vehicle movement detector 110 may detect whether a vehicle is capable of moving after parking.

In accordance with the present invention, whether the vehicle is parked can be determined by checking the start-off state of the vehicle after driving, and whether the vehicle is parked can be recognized by the control module of the event detection unit 100 described above, described later. The smart key control unit 200 may detect a start-off state.

When the vehicle movement detection unit 110 is parked in a state in which the side brake of the vehicle is released, the vehicle movement detection unit 110 may determine whether the vehicle is moving by sensing the inclination of the parked ground.

Vehicle users often do double parking due to lack of parking space, or release the side brake after parking to facilitate the movement of other vehicles parked adjacent to the vehicle. In this case, when the user is unfamiliar or when the slope of the ground changes rapidly due to an obstacle or other factors, the vehicle may be inclined or moved in the direction of the slope if the user releases the side brake without considering the slope of the ground.

According to this embodiment, the vehicle movement detection unit 110 may detect the inclination of the ground and determine whether there is a possibility that the corresponding vehicle moves in the sensed inclination. The sensed inclination can be compared to a predetermined threshold, and if the inclination exceeds the threshold, it can be predicted that the vehicle will move.

The threshold value to be compared with the inclination may be set to various values according to the weight of the vehicle and the state of the ground. To this end, the vehicle movement detection unit 110 may additionally sense the state of the road surface. The threshold may be set differently depending on whether the road surface is unpaved road or asphalt, or whether water such as rain is on the road surface or snow or ice is present.

The image imaging module 120 may image a vehicle front side and determine whether the vehicle is parked in a parking prohibited area. The image capturing module 120 may be implemented by including a black box mounted inside the vehicle, and may include an image analysis unit capable of extracting a specific image from the captured image and performing various judgments based on the extracted image. have.

For example, when a user parks a vehicle in a parking prohibited area or a towing area, an image indicating this may be captured by a black box. The image analysis unit may detect that the vehicle is parked incorrectly by comparing the captured image with a mark indicating a parking prohibition that has already been stored or a mark indicating a towing area.

It is preferable that the emergency detection of the event detection unit 100 is performed within a predetermined operation time after the vehicle is parked, and the operation time is such that the smart key control unit 200 and the smart key 300 can communicate. It may be set in consideration of a time, that is, a user movement distance at which the smart key 300 can operate. For example, the operation time is preferably set to a few seconds to tens of seconds that the user can easily return to the vehicle after parking.

The smart key control unit 200 may transmit an emergency alarm signal to the smart key 300 when it is determined that an emergency event has occurred in the parked vehicle through the event detection unit 100. The smart key control unit 200 may be implemented as a smart key ECU mounted on a vehicle, and may include a communication module (not shown) for communicating with the smart key 300.

The communication module may include a radio frequency (RF) module, a low frequency (LF) module, a bluetooth module, or a wireless-fidelity (Wi-Fi) module.

The emergency alarm signal may be a signal for transmitting a situation in which an emergency event has occurred, or may be a signal capable of distinguishing whether an emergency event has occurred. For example, when a vehicle movement possibility is detected by the vehicle movement detection unit 110 so that individual emergency events can be distinguished, a vehicle movement warning signal may be transmitted to the smart key 300, and the image imaging module 120 may If the parking area is detected as wrong, a parking error signal may be transmitted to the smart key 300.

As illustrated, the smart key 300 may include a communication unit 310 and a user interface unit 320.

In operation 240, the smart key control unit 200 may transmit an emergency alarm signal informing of the danger of the vehicle movement, that is, the vehicle movement warning signal to the smart key 300.

In step 210, if the side brake is not released as a result of determination, and the inclination detected in step 230 does not exceed the threshold, the possibility of moving the vehicle after parking is very low, so that detection of the next emergency situation is performed in step 250 do.

In step 250, the image imaging module 120 of the event detection unit 100 may image the vehicle surroundings to determine whether the vehicle is parked in a parking prohibited area.

In step 260, if the vehicle is parked in a no-parking zone, as described above, the smart key control unit 200 may transmit a signal for a parking error to the smart key 300. The user can know that the vehicle has been parked in a no-parking zone within a predetermined time after parking of the vehicle, preferably in a situation that does not significantly deviate from the parking area.

On the other hand, if the vehicle is not parked in the no parking zone, the smart key control unit 200 does not need to generate an emergency alarm signal.

In this embodiment, it is determined whether an emergency event according to the danger of vehicle movement is first detected and then parked in a no-parking zone, but the present invention is not limited to this and the detection order may be changed.

3A and 3B are views illustrating a display unit of a smart key according to an embodiment of the present invention.

The smart key 300 according to the present embodiment may include a display unit as a user interface unit, and the emergency alarm signal transmitted from the smart key control unit 200 to the smart key 300 may include various images as shown in FIG. 3A or 3B. Can be provided to the user.

After determining that the user terminal 400 is inside the vehicle after parking the vehicle, the smart key control unit 200 may transmit a terminal alarm signal indicating whether the user terminal 400 is present to the smart key 300.

To this end, the user terminal 400 may be registered in advance with the smart key control unit 200. The user terminal 400 may perform short-range communication to transmit a constant response signal in response to the signal received from the smart key control unit 200. For example, when short-range communication is performed with the user terminal 400, the smart key control unit 200 may determine that the user terminal 400 exists inside the vehicle. The range of the short-range wireless communication capable of determining whether the user terminal 400 exists in the vehicle may be changed by the vehicle system or the user's setting.

A user who leaves the user terminal 400 in the vehicle may return to the vehicle and search for the user terminal 400 after parking after moving through the terminal alarm signal received by the smart key 300. The terminal alarm signal may be displayed on the smart key 300 in a unique pattern or a specific image as shown in FIG. 3A or 3B.

On the other hand, according to another example, when the smart key control unit 200 determines that the smart key 300 is inside the vehicle after parking the vehicle, the smart key alarm signal indicating whether the smart key 300 is present is displayed in the user terminal ( 400).

The user may leave the smart key 300 instead of the user terminal 400 in the vehicle. When the ignition is turned off, the smart key control unit 200 may check whether the smart key 300 is present in the vehicle through short-range communication, and transmit the confirmed result to the user through the user terminal 400. Accordingly, the user can easily grasp the location of the smart key 300 and cope with the absence of the smart key 300.
