Hereinafter, an embodiment embodying the present invention will be described with reference to FIGS. FIG. 1 is a block diagram illustrating the configuration of the door lock control system 1.
As shown in FIG. 1, the door lock control system 1 includes a door lock control device 2 as a door lock operation device. The door lock control device 2 includes a door lock control unit 3 as on-vehicle system control means and second output control means. The door lock control unit 3 inputs a shift position signal SG1 of the vehicle C from a neutral start switch 30 mounted on the vehicle C (see FIG. 2). Further, the door lock control unit 3 inputs a brake detection signal SG2 from a brake switch 31 provided in a parking brake switch device (not shown) of the vehicle C.

  The door lock control device 2 has an obstacle detection unit 4 as an obstacle detection means. For example, when the ignition switch is turned on and power is supplied, the obstacle detection unit 4 controls the obstacle detection sensor 32 provided in the vehicle C to detect an obstacle. As the obstacle detection sensor 32, an ultrasonic sensor, a millimeter wave radar, a laser radar, or the like can be used. In this embodiment, as shown in FIG. 2, four first to fourth obstacles composed of ultrasonic sensors are used. Detection sensors 32a to 32d are provided on the front left side, the front right side, the rear left side, and the rear right side, respectively. Note that the first to fourth obstacle detection sensors 32a to 32d will be described simply as the obstacle detection sensor 32 when not described in particular.

  The obstacle detection sensor 32 transmits ultrasonic waves around the vehicle C under the control of the obstacle detection unit 4. When there is an obstacle around the vehicle C, the obstacle detection sensor 32 receives the reflected wave reflected by the obstacle and transmits a reception signal SG3 to the obstacle detection unit 4. The obstacle detection unit 4 detects the distance from the obstacle based on the time from when the ultrasonic wave is transmitted until the reflected wave is detected. Further, the position of the obstacle is specified from the position of the sensor that has detected the reflected wave and the distance to the obstacle among the first to fourth obstacle detection sensors 32a to 32d.

The door lock control device 2 also includes an image input unit 5 as image data acquisition means, an overhead conversion processing unit 6 as an overhead conversion means as an overhead conversion means, an output control means, a first output control means, and a second output control. An image composition unit 7 and a drawing processing unit 9 are provided as means. The image input unit 5 inputs the image data G by controlling the camera 33 as a photographing device provided in the vehicle C. As shown in FIG. 2, the vehicle C includes a front camera 33a attached to the front side of the vehicle, a left side camera 33b attached to the left side, a right side camera 33c attached to the right side, and a rear camera attached to the rear side of the vehicle. 33d is attached. The image input unit 5 inputs front image data Ga obtained by photographing the front of the vehicle from the front camera 33a. Further, left side image data Gb and right side image data Gc obtained by photographing the left side and the right side of the vehicle C are input from the left side camera 33b and the right side camera 33c, respectively. Further, rear image data Gd obtained by photographing the rear of the vehicle is input from the rear camera 33d. In addition, when it demonstrates without distinguishing each camera 33a-33d and each image data Ga-Gd, it demonstrates as the camera 33 and the image data G only.

  The overhead view conversion processing unit 6 inputs each image data G via the image input unit 5, performs a known overhead view conversion process on each image data G, and generates overhead image data G1. That is, each image data Ga to Gd photographed from each viewpoint of each camera 33a to 33d is coordinate-converted into an image viewed from one viewpoint set above the vehicle C in the vertical direction. Thereby, each image data Ga-Gd is converted into the image data seen from the same viewpoint. At this time, a region that cannot be overhead-converted may be masked. When the overhead image data G1a to G1d are generated, the overhead view conversion processing unit 6 outputs the overhead image data G1a to G1d to the image composition unit 7.

  The image compositing unit 7 combines the overlapping regions of the overhead image data G1 by superimposing and overlays the overhead view of the surroundings of the vehicle C as shown in FIGS. 3 (a) and 3 (b). Generate. Then, the generated overhead view synthesis data G2 is output to the display 10 as a display means. Thereby, the front, back, left side, and right side images of the vehicle C are displayed.

  Moreover, the image composition unit 7 superimposes the vehicle image data 7a stored in the storage unit (not shown) on the overhead view synthesis data G2 at a position corresponding to the current position of the vehicle C in the overhead view synthesis data G2. As a result, as shown in FIGS. 3A and 3B, the vehicle overhead image 22 based on the vehicle image data 7a is superimposed on the overhead image 21 based on the overhead synthesis data G2, and the vehicle C and its surroundings are superimposed. Is displayed on the display 10. By confirming the operation screen 20, the driver can grasp the relative position between the vehicle C and the white line or obstacle displayed in the overhead image 21.

  Further, the image composition unit 7 draws a door lock operation switch S as a door lock operation unit in the vehicle image data 7a. In the present embodiment, the door lock operation switch S includes five door lock operation switches S1 to S5, and the front seat left door D1, the rear seat left door D2, the front seat right door D3, and the rear by contact of the user's finger. Each door D such as the right seat door D4 and the back door D5 is locked or unlocked. Moreover, each door lock operation switch S1-S5 is each displayed on the position of each door D1-D5 used as the object of operation.

  The image synthesizing unit 7 displays the door lock operation switch S as either active or inoperable that cannot be operated. 3 (a) and 3 (b) both show a state in which the door lock operation switches S1 to S5 are in an operable state (active), and FIG. 3 (a) shows that the doors D1 to D5 are in an operable state. The door lock operation switches S1 to S5 in a locked (locked) state are shown. FIG. 3B shows the door lock operation switches S1 to S5 in a state where the doors D1 to D5 are unlocked (unlocked). The locked door lock operation switch S is different from the unlocked door lock operation switch S in terms of design, color, shape, and the like.

  For example, in FIG. 3A, when the user's finger contacts the display position of the locked door lock operation switch S1, the touch panel control unit 8 (see FIG. 1) of the door lock control device 2 detects the contact position. Then, a detection signal indicating the contact position is output to the door lock control unit 3.

  The door lock control unit 3 outputs a command signal for unlocking the door D1 to the lock system control computer 35 provided in the vehicle C based on the detection signal. The lock system control computer 35 controls a door lock assembly As having a door lock motor, a door lock mechanism, and the like. In this embodiment, when the five first to fifth door lock assemblies 36 to 40 are controlled and a command signal for unlocking the door D1 is input, the first door lock assembly 36 corresponding to the door D1 is controlled. Unlock the door D1.

  Further, when the door D1 is unlocked, the door lock control unit 3 controls the image composition unit 7, and the door lock operation switch S1 corresponding to the door D1 is unlocked as shown in FIG. To. In FIG. 3B, all door lock operation switches S are unlocked, but only the operated switch is unlocked. When a finger touches any of the unlocked door lock operation switches S1 to S5, the touch panel control unit 8 detects the contact position, and the door lock control unit 3 operates the operated door lock operation switches S1 to S1. S5 is determined. Then, the door D to be locked is determined, the corresponding door lock assembly As is controlled via the lock system control computer 35, and the door D is locked.

  When the obstacle detection unit 4 detects an obstacle around the vehicle C, the image composition unit 7 deactivates the door lock operation switches S1 to S5. Specifically, as shown in FIG. 3C, when the door lock control unit 3 detects an obstacle around the vehicle C based on the obstacle detection unit 4, the door lock operation switch S5 close to the obstacle is detected. Is deactivated. The door lock operation switch S switched to inactive is different in design, color, shape, and the like from the active door lock operation switch S. FIG. 3C shows a state where all the door lock operation switches S1 to S4 are inactive. At the same time, the door lock control unit 3 controls the lock system control computer 35 to lock the door D corresponding to the deactivated door lock operation switch S.

  As shown in FIG. 3C, the display format of the inactive door lock operation switch S may be changed only in color from that in the active case, or may be toned down. At this time, even if the touch panel control unit 8 detects contact between the inactive door lock operation switches S1 and S2 and the user's finger, the door lock control unit 3 does not output a command signal to the lock system control computer 35. .

  For example, as illustrated in FIG. 4A, when the obstacle detection unit 4 detects the wall W behind and to the right of the vehicle C, the relative distance between the vehicle C and the obstacle is further calculated. And it is judged whether the relative distance is below a predetermined distance. The predetermined distance is set based on the rotation range of the doors D4 and D5. For example, the predetermined distance is a rotation range of the doors D4 and D5 or a length obtained by adding a necessary minimum interval to the rotation range of the doors D4 and D5. It has become. When the door lock control unit 3 determines that the relative distance to the obstacle is equal to or less than the predetermined distance, the door lock control unit 3 deactivates the door lock operation switch S. At this time, as shown in FIG. 4B, among the door lock operation switches S1 to S5, the rear and right side door lock operation switches S3 to S5 close to the wall W are deactivated. At this time, even if the touch panel control unit 8 detects contact of the inactive door lock operation switches S <b> 3 to S <b> 5, the door lock control unit 3 does not output a command signal to the lock system control computer 35.

  Also, as shown in FIG. 5A, when the obstacle detection unit 4 detects the adjacent vehicle C1 on the left and right of the vehicle C and determines that the distance to the right adjacent vehicle C1 is within a predetermined distance. The door lock control unit 3 puts the right side door lock operation switches S3 and S4 into a locked state and deactivates them.

  Also, as shown in FIG. 6A, when the door lock control unit 3 determines that a moving obstacle such as a motorcycle is approaching from the rear of the vehicle C based on the obstacle detecting unit 4, the moving obstacle The door lock operation switches S3 and S4 on the right side close to the traveling direction are deactivated.

  Next, the processing procedure of this embodiment is demonstrated according to FIG.7 and FIG.8. First, when the ignition switch is turned on and power is supplied, the door lock control unit 3 inputs the shift position signal SG1 and the brake detection signal SG2 from the neutral start switch 30 and the brake switch 31, respectively. Then, it is determined whether or not the shift position is parking and the parking brake is on (step S1-1). The determination in step S1-1 is repeated until this condition is satisfied.

  If it is determined that the shift position is parked and the parking brake is on (YES in step S1-1), the image input unit 5 acquires each image data G from each camera 33 (step S1-2).

  When each image data G is input, the overhead conversion processing unit 6 performs overhead conversion of each image data G to generate overhead image data G1 (step S1-3). Further, the image synthesis unit 7 synthesizes the overhead view image data G1 to generate the overhead view synthesis data G2, and the drawing processing unit 9 outputs the overhead view synthesis data G2 to the display 10. Further, the image composition unit 7 outputs the vehicle image data 7a to a position corresponding to the current position of the vehicle C in the overhead view composition data G2, and displays the operation screen 20 (step S1-4).

  Further, the image composition unit 7 outputs the door lock operation switches S1 to S5 to predetermined positions of the vehicle overhead image 22 (step S1-5). At this time, the door lock control unit 3 detects the lock state of each door lock assembly As from the lock system control computer 35, and displays a locked door lock operation switch S for the locked door D. Then, for the unlocked door D, the unlocked door lock operation switch S is displayed.

  Moreover, the door lock control part 3 performs a situation determination process based on the obstacle detection sensor 32 (step S1-6). When an obstacle is detected around the vehicle C, a relative distance between the vehicle C and the obstacle is calculated, and it is determined whether or not the relative distance is within a predetermined distance. When it is determined that the relative distance is within the predetermined distance, it is determined that an obstacle is approaching the door. Further, the door D close to the obstacle or the door D in the traveling direction of the obstacle is specified.

  When the vehicle surrounding situation is determined, the door lock control unit 3 determines whether an obstacle is detected around the door as a result of the situation determination process (step S1-7). If it is determined that there is an obstacle around the door (YES in step S1-7), the door lock operation switch S of the door D near the obstacle is deactivated (step S1-8). More specifically, as shown in FIG. 4A, when the wall W is detected as an obstacle around the door on the right side and the rear side of the vehicle C, the right side door lock operation switches S3, S4 and The rear door lock operation switch S5 is deactivated. At this time, the driver confirms the relative position between the wall W and the vehicle overhead image 22 in the overhead image 21 and opens the doors D3 to D5, so that the wall W and the doors D3 to D5 come into contact with each other. Can be expected. In addition, it is possible to immediately understand the factor that the door lock operation switches S3 to S5 are inactive.

In FIG. 5A, when the adjacent vehicle C1 is detected as an obstacle around the door on the right side of the vehicle C, the door lock operation switches S3 and S4 are deactivated. At this time, the driver can confirm from the overhead image 21 that the space between the adjacent vehicle C1 and the vehicle C is small. Therefore, when the doors D3 and D4 are opened, the adjacent vehicle C1 and the doors D3 and D4 are opened. Can be determined in advance. In addition, it is possible to immediately understand the reason why the door lock operation switches S3 and S4 are inactive.

  As shown in FIG. 6A, when the motorcycle M is detected as an obstacle around the door on the right side of the vehicle C, as shown in FIG. 6B, the door lock operation switch S3 on the right side is displayed. , S4 are deactivated. At this time, the driver can confirm from the bird's-eye view image 21 that the motorcycle M is approaching. For this reason, when the doors D3 and D4 are opened, it is dangerous because another passenger may open the door D4 and get off the vehicle D even though the motorcycle M is approaching. Can do. Even if the motorcycle M is not displayed in the bird's-eye view image 21, the door lock operation switches S3 and S4 are inactive, so it can be suggested that there is an obstacle around.

  On the other hand, if there is no obstacle around the door (NO in step S1-7), it is determined whether the shift position is switched to other than parking or the parking brake is turned off (step S1-9). If it is determined that the shift position is other than parking or the parking brake is off (YES in step S1-9), the operation screen 20 is erased by the drawing processing unit 9, and the process ends. If the shift position is parking and the parking brake is off (NO in step S1-9), the process returns to step S1-1 and the above-described processing is repeated.

  Next, processing of the door lock control unit 3 when the operation screen 20 is displayed will be described with reference to FIG. The door lock control unit 3 waits for operation of the door lock operation switch S via the touch panel control unit 8 (step S2-1). If it is determined that the finger has touched the display position of the door lock operation switch S (YES in step S2-1), the door lock control unit 3 determines whether the door lock operation switch S is active (step). S2-2).

  If it is determined that the door is active (YES in step S2-2), the door lock control unit 3 controls the door lock assembly As corresponding to the operated door D via the lock system control computer 35, and controls the door D. Lock or unlock (step S2-3).

  On the other hand, if it is determined that the door lock operation switch S is inactive (NO in step S2-2), the door lock control unit 3 does not unlock the door lock even if the door lock operation switch S is operated, and locks the door. Maintain (step S2-4). For this reason, it is possible to prevent the driver and other occupants from unlocking the door D by mistake even though the obstacle is around the door.

According to the above embodiment, the following effects can be obtained.
(1) In the above embodiment, the image synthesizing unit 7 and the drawing processing unit 9 display the door lock operation switch S for locking and unlocking the door D on the screen of the display 10. Further, when the obstacle detection unit 4 detects an obstacle around the vehicle C, the door lock operation switch S close to the obstacle is locked and the door lock operation switch S is made inoperable and inactive. . For this reason, for example, although the obstacle such as the wall W or the adjacent vehicle C1 exists in the rotation range of the door D, the door D is unlocked by mistake, and the door D and the obstacle are in contact with each other. Can be prevented. In addition, the door is unlocked to prevent the driver or other occupants from opening the door D accidentally even though a moving obstacle such as a motorcycle M or a bicycle is approaching. Can do.

(2) In the above embodiment, the image data G obtained by photographing the vehicle periphery with the camera 33.
Based on the above, the bird's-eye view image 21 overlooking the vehicle periphery and the vehicle bird's-eye view image 22 overlooking the vehicle C are displayed on the operation screen 20, and the door lock operation switch S is superimposed on the vehicle bird's-eye view image 22. For this reason, it becomes easy to grasp the relative position of the surrounding obstacle and the vehicle C by the bird's-eye view image 21 and the vehicle bird's-eye view image 22. Therefore, it is possible to easily understand the cause of the door lock operation switch S being switched to inactive. Furthermore, since the door lock operation switch S is superimposed on the position of each door D in the vehicle overhead view image 22, it is easy to understand which door D is the operation button, and the operability can be improved.

  (3) In the above embodiment, when an obstacle around the door is detected, only the door lock operation switch S near the obstacle is deactivated and the other door lock operation switches S are activated. The minimum door D can be locked and the other door D can be locked or unlocked. For this reason, a user's convenience can be improved.

In addition, you may change the said embodiment as follows.
The touch panel control unit 8 is included in the door lock control device 2, but the touch panel control unit 8 may be omitted.

  The obstacle detection unit 4 may determine whether the detected obstacle is a moving obstacle such as a motorcycle or a stationary obstacle such as a wall. In this case, the obstacle detection unit 4 repeatedly specifies the position of the obstacle for a predetermined time, and when the position of the obstacle is moving, the obstacle is a moving obstacle such as a motorcycle. If the position of the obstacle has not moved, it is determined that the obstacle is a stationary obstacle such as a wall. When the obstacle is a stationary obstacle, it is determined whether or not the distance from the vehicle C is within the predetermined distance L1, and when the obstacle is a moving obstacle, the distance from the vehicle C is the predetermined distance. It may be determined whether it is within L2 (> predetermined distance L1). When the distance between the obstacle and the vehicle C is within the predetermined distances L1 and L2, the door lock operation switch S is deactivated.

  In the above embodiment, each door lock operation switch S is displayed for each of the five doors D of the vehicle C. However, the door lock operation switch S is displayed for one to four doors D. Also good.

  In the above embodiment, one door lock operation switch S is displayed for one door D on the operation screen 20, but “lock” is displayed for one door D as shown in FIG. In addition, an operation screen 50 displaying two door lock operation switches Sa and Sb for operating “unlock” may be used.

  In the above embodiment, the overhead image 21 is displayed on the operation screen 20, but as shown in FIG. 10, the door lock operation switch S is set to 1 on the peripheral image 51 based on the image data G before the overhead conversion. One or a plurality of operation screens 50 may be displayed. FIG. 10 is a monitor image 52 based on the rear image data Gd photographed by the rear camera 33d. Also in this case, the driver can confirm the obstacle around the door D on the monitor image 52.

  In the above embodiment, the overhead image 21 is displayed on the operation screen 20, but the image is not limited to the image based on the image data G acquired from the camera 33. For example, only the vehicle overhead image 22 may be displayed. Alternatively, as shown in FIG. 11, an operation screen 53 displaying only the door lock operation switch S may be used. In this case, when an obstacle is detected around each door D, the door lock control unit 3 unlocks the door lock operation switch S corresponding to the door D.

In the above embodiment, the door lock operation switch S is deactivated when an obstacle is detected, but a warning sound may be output from a speaker (not shown).
In the above embodiment, when the inactive door lock operation switch S is operated, the output of the command signal from the door lock control unit 3 to the lock system control computer 35 is prohibited. In addition to this, the inactive door lock operation switch S may be simply a dummy button that is not detected by the touch panel control unit 8 even if a finger touches it.

  In the above embodiment, the obstacle detection sensor 32 detects the obstacle. However, the image data G photographed by the camera 33 may be detected by image processing.

In the above embodiment, the door lock operation switch S is displayed on the display 10, but may be displayed on, for example, an instrument panel.
In the above embodiment, the door D close to the detected obstacle is locked, and the door lock operation switch S of the door D is made inactive. Accordingly, the door D may be locked. For example, an occupant detection device such as a weight sensor incorporated in a seat or an image detection sensor is provided in the vehicle C to determine whether the occupant is seated, and when an obstacle is detected, the door of the seat on which the occupant is seated D may be locked. Further, it may be determined whether or not the occupant is a child by the occupant detection device, and when the child is detected, the door D of the seat on which the child is seated may be locked. Then, the door lock operation switch S corresponding to the locked door D may be deactivated.

  The door lock control device 2 may lock the door D according to the location where the vehicle C is parked based on a navigation device or the like (not shown) provided in the vehicle C. For example, when it is determined that the vehicle C is parked on the road based on the navigation device, the door D in the direction in which the other vehicle passes may be locked. That is, when it is determined that the vehicle C is parked at the left end of the road, the right door D is locked. At this time, when it is determined that there is a narrow sidewalk on the left side of the vehicle C, the left door D may be locked. Then, the door lock operation switch S corresponding to the locked door D may be deactivated.
