As described above, the link mechanism unit 45 is driven by the rotational force of the door drive motor 41 to open and close the door 52. As shown in FIG. 6, the link mechanism unit 45 according to the present embodiment includes a crank arm 45a, a link 45b, and a link member 45c. One end of the crank arm 45a is connected to the drive shaft 43 described above, and the other end is connected to one end of the link 45b. The other end of the link 45b is connected to one end of the link member 45c, and the other end of the link member 45c is pivotally supported by the support shaft 44a. The support shaft 44a is connected to a bearing portion 44b provided on the vehicle body side, whereby the door and the vehicle body are linked. The link member 45c has a substantially central portion in the longitudinal direction that penetrates the inside of the check mechanism portion 60 provided in the door 52 and engages with the check member 63 housed in the housing 61 of the check mechanism portion 60. A groove 62 is formed. Similarly, the check member 63 is urged in a direction to sandwich the link member 45c from above and below by an elastic body 64 housed in the housing 61 of the check mechanism portion 60.
As the door 52 is opened and closed, the link member 45 c slides inside the check mechanism 60. When the slopes provided before and after the groove 62 are in contact with the protrusions provided on the check member 63, a large sliding resistance is generated by the biasing force of the elastic body 64, and the movement of the link member 45c is caused. Decelerated. When the groove 62 of the link member 45c is engaged with the convex portion of the check member 63, the link member 45c is held with a predetermined check force. The door 52 is held in the half-open position. As the link member that generates such a check force, an existing link member that is normally provided in a manual door that does not include a door opening / closing device can be used as it is.
When the strength of the link member 45c is insufficient, a deformation prevention guide member 65 may be provided above and below the link member 45c as shown in FIG. 7 to restrict the vertical displacement of the link member 45c.
[0038]
The connecting portion between the link 45b and the crank arm 45a, and the connecting portion between the link 45b and the link member 45c are all constituted by ball joints. The ball joint includes a rotating member having a spherical surface, and the spherical surface is slidably contacted with inner surfaces of bearing portions provided at both ends of the link 45b so as to be three-dimensionally rotatable. With this configuration, the link 45b links the link member 45c and the crank arm 45a while maintaining the linear shape, and transmits the output of the drive shaft 44 to the link member 45c.
[0039]
In the link mechanism 45 of the present embodiment, when the door drive motor 41 rotates forward and backward with the clutch 42 being ON-controlled, this rotational force is transmitted to the drive shaft 43 via the clutch 42. Then, the crank arm 45 a rotates around the connecting portion with the drive shaft 43 by the output of the drive shaft 43.
For example, as shown in FIG. 2, even when the door 52 is fully opened and the door drive motor 41 is in a stopped state, the load resistance of the link mechanism unit 45 and the door drive motor 41 is applied to the door 52 via the clutch 42. As a result, the door 52 can be held in the fully open position.
On the other hand, in a state in which the clutch 42 is OFF controlled, the connection between the door drive motor 41 and the link mechanism 45 is released, so that the door 52 can be manually operated. At this time, since the load of the door drive motor 41 and the link mechanism unit 45 is not applied to the door 52, the passenger can easily open and close the door 52.
[0040]
(Operation of vehicle door opening and closing device)
Next, the operation of the vehicle door opening / closing device S having the above-described configuration will be described.
First, FIG. 11 thru | or FIG. 16 is a flowchart which shows control of the vehicle door opening / closing apparatus which concerns on one Embodiment. 11 to 16, the operation of the door opening / closing device S when the door 52 is opened / closed by an operation by the inner door opening / closing switch 15 or the outer door opening / closing switch 16 provided in the vehicle will be described.
When the door opening / closing operation is performed by the wireless remote controller 11, a signal receiving unit from the wireless remote controller 11 is provided on the outside and inside of the vehicle, respectively, and the inside operation or the outside operation is distinguished depending on which is detected. . The control in this case is the same as the opening / closing operation by the door opening / closing switches 15 and 16.
[0041]
11 to 16, the operation of the vehicle door opening and closing device S in the present embodiment will be described. 11 to 16 is controlled by a CPU (not shown) of the control unit 30.
In the following description, the inside door opening / closing switch is simply referred to as “inside SW”, and the outside door opening / closing switch is simply referred to as “outside SW”. In addition, the inner door switch opening operation signal and the inner door switch closing operation signal are collectively referred to simply as “inner opening / closing signal”, and the outer door switch opening operation signal and the outer door switch closing operation signal are collectively referred to simply as “outer opening / closing operation signal”. "Medium signal".
The process starts on condition that at least one switch of the switch group including the inner SW 15 and the outer SW 16 is operated. First, it is determined whether or not an accident signal is input to the vehicle state holding unit 36 (step S1101). If it is determined that an accident signal has been input to the vehicle status holding unit 36 (step S1101: YES), the process is switched to manual operation (S1102) and the process ends.
The accident signal is a signal that is detected by the sensor detection signal detection unit 27 and input to the vehicle status holding unit when the impact sensor 74, the air pressure sensor 75, and the airbag operation sensor of the vehicle status detection unit 70 are turned on. is there. When an accident signal is input, there is a high possibility that the vehicle is in an urgent state, so the automatic door opening / closing operation is canceled and switched to manual operation.
[0042]
When it is determined that the accident signal is not input to the vehicle status holding unit 36 (step S1101: NO), it is determined whether the inner SW 15 and the outer SW 16 are operated simultaneously (step S1103). If it is determined that the inner SW 15 and the outer SW 16 are operated simultaneously (step S1103: YES), the operation of the outer SW 16 is invalidated (step S1104), the process proceeds to step S1106, and the inner open / close signal is set to HIGH (step S1106). If it is determined that the inner SW 15 and the outer SW 16 are not operated simultaneously (step S1103: NO), it is determined whether there is an inner SW operation (step S1105). As described above, even when the inner SW 15 and the outer SW 16 are accidentally operated simultaneously, the operation of the outer SW 16 is invalidated, so the operation of the inner SW 15 is given priority. If it is determined that there is an inside SW operation (step S1105: YES), the inside open / close signal is set to HIGH (step S1106). The HIGH signal of the inner SW 15 is output during a period from when the inner SW 15 is operated until the automatic opening / closing process of the door 52 is completed, and is set LOW when the automatic opening / closing process of the door 52 is completed. When the inside opening / closing signal is set to HIGH (step S1106), it is determined whether the vehicle speed is 0, that is, whether the vehicle is parked or stopped (step S1107). If the vehicle speed is not 0 (step S1107: NO), it is determined that the vehicle is running, the process proceeds to S1113, and the inside open / close signal is set to LOW (step S1113). Thereafter, the process ends. In order to prevent the operation of the door 52 during traveling of the vehicle, the operation is stopped, that is, the switch operation is invalidated. If the vehicle speed is 0 (step S1107: YES), it is determined whether or not the operating direction of the inner SW 15 is the open direction (step S1108).
[0043]
When it is determined that the operation direction of the inner SW 15 is not the open direction (step S1108: NO), it is determined whether or not the door position is in the fully closed state (step S1109).
That the door 52 is fully closed can be detected by a door open / closed state detection sensor (not shown). If the door 52 is in the fully closed state (step S1109: YES), it is impossible to close the door 52 any more, so that it is regarded as an erroneous operation, and the process proceeds to S1113, and the inside is being opened / closed. Set the signal to LOW. Thereafter, the process ends. If the door 52 is not fully closed (step S1109: NO), it is determined that the operation for closing the door 52 is effective, and the door closing process is executed (step S1110). This door closing process performs the processes shown in FIGS. Next, after the door closing process is completed, the process proceeds to S1113, the inside open / close signal is set LOW, and the process ends.
[0044]
When it is determined that the operation direction of the inner SW 15 is the open direction (step S1108: YES), it is determined whether or not the door position is smaller than the set value (step S1111). That is, it is determined whether or not the door position is smaller than a preset value (for example, 60 degrees of opening). The door position is grasped by the door opening angle. The door opening angle is obtained by converting the angle by the counter 34 of the control circuit 31 based on a signal from the encoder 22 of the detection unit 20. The angle at which the door 52 is opened can be set in advance to, for example, 60 degrees. In step S1111, the door opening angle at that time is compared with the set value. If it is determined that the door position is not less than the set value, that is, greater than or equal to the set value (step S1111: NO), it is determined that further door opening is inappropriate, the process proceeds to S1113, and the inside open / close signal is displayed. Set to LOW (step S1113). Thereafter, the process ends.
If it is determined that the door position is smaller than the set value (step S1111: YES), it is determined that the operation for opening the door 52 is valid, and the door opening process is executed (step S1112). This door opening process performs the process of FIG. Next, after the door opening process is completed, the process proceeds to S1113, the inside open / close signal is set LOW, and the process is terminated.
[0045]
If it is determined that there is no inner SW operation (S1105: NO), the process proceeds from G in FIG. 11 to G in FIG. 12 to step S1201 in FIG. 12 to determine whether or not the inner open / close signal is HIGH. (Step S1201).
If it is determined that the inner opening / closing signal is HIGH (step S1201: YES), the outer switch is disabled (step S1210), and the process ends. The process proceeds to step S1201 when at least one switch of the switch group including the inner SW15 and the outer SW16 is operated, but the operation is not the inner SW15, that is, the outer SW16 is operated. It is. However, there is a possibility that the outside SW 16 may be operated while the processing based on the inside opening / closing signal is being performed. In this case, the door opening / closing operation by the command of the outside SW 16 is contrary to the intention of the passenger. There is a high possibility that the passenger will be there or something that passengers do not want. For example, when the outside SW16 is pressed because someone else's belongings traveling on the outside of the vehicle touches the outside SW16, or the outside SW16 operates the outside SW16 to automatically open and close the door 52 against the intention of the passenger The case where it is going to let it be assumed is assumed. In such a case, it is considered appropriate to invalidate the operation of the outside SW and validate the operation of the inside SW 15 that is considered to reflect the intention of the passenger in the vehicle. Therefore, when the outside SW 16 is operated and the inside open / close signal is HIGH, the operation of the outside SW 16 is invalidated.
[0046]
When it is determined that the inner opening / closing signal is not HIGH (step S1201: NO), it is determined whether the outer opening / closing signal is HIGH (step S1202). If it is determined that the outside open / close signal is HIGH (step S1202: YES), the outside SW is invalidated (step S1210), and the process ends. In other words, when the outside SW is further operated while the door automatic opening / closing operation is performed according to the command from the outside SW 16, the subsequent outside SW operation is invalidated. Since the outside SW is disposed outside the door 52, it is considered that the outside SW is likely to be operated by a person other than the vehicle passenger. Therefore, in the present embodiment, it is intended to prevent the operation from being easily switched. However, when the outside SW is further operated during the automatic opening / closing of the door 52 by the outside SW command, the later operation may be prioritized for the convenience of the operator.
[0047]
When it is determined that the outside open / close signal is not set HIGH (step S1202: NO), the outside open / close signal is set HIGH (step S1203), and it is determined whether or not the outside SW 16 is operated in the opening direction (step S1203). Step S1204). If it is determined that the outside SW 16 is not operated in the opening direction (step S1204: NO), it is determined whether or not the door position is fully closed (step S1205). If the door position is not fully closed (step S1205: NO), a door closing process is performed (step S1206). In this door closing process, the processes of FIGS. 14 and 15 are performed. When the door closing process in step S1206 ends, the outside open / close signal is set to LOW (step S1209), and the process ends.
If the door position is in the fully closed state (step S1205: YES), it is determined that no further closing operation is necessary, the process proceeds to S1209, and the outside open / close signal is set to LOW. Thereafter, the process ends.
[0048]
If it is determined that the operation of the outside SW 16 is in the opening direction (step S1204: YES), it is determined whether or not the door position is smaller than the set value (step S1207). When the door position is smaller than the set value (step S1207: YES), a door opening process is performed (step S1208). In this door opening process, the process of FIG. 13 is performed. When the door opening process in step S1208 ends, the outside open / close signal is set to LOW (step S1209), and the process ends.
If the door position is not smaller than the set value, that is, if it is greater than or equal to the set value (step S1207: NO), it is determined that further opening operation is inappropriate and the process proceeds to S1209, and the outside open / close signal is set to LOW. Set. Thereafter, the process ends.
[0049]
Next, details of the door opening process in step S1112 in FIG. 11 and step S1208 in FIG. 12 will be described with reference to FIG.
First, it is determined whether or not the obstacle signal detected by the obstacle sensor 72 of the vehicle state detection unit 70 and detected by the sensor detection signal detection unit 27 is input to the vehicle state holding unit 36 (step S1301). When the obstacle signal is input to the vehicle state holding unit 36 (step S1301: YES), the timer T1 is started (S1302), and it is determined whether the timer T1 is equal to or greater than a set value (step S1303). ). If the timer T1 is greater than or equal to the set value (step S1303: YES), it is determined that the obstacle has not been removed, and the process is terminated. When the timer T1 is smaller than the set value (step S1303: NO), it is determined again whether or not an obstacle signal is input to the vehicle state holding unit 36 (step S1304). If it is determined that the obstacle signal is being input to the vehicle status holding unit 36 at that time (step S1304: YES), the process returns to step S1303 to determine whether or not the timer T1 is equal to or greater than the set value. If it is determined that no obstacle signal has been input to the vehicle status holding unit 36 at that time (step S1304: NO), it is determined that the obstacle has been removed, and the process proceeds to step S1305 via H. The door drive motor 41 and the clutch 42 are driven. That is, in steps S1302 to S1304, whether or not the detected obstacle is eliminated is monitored within the time set in the timer T1 (for example, 3.0 seconds). Since the data input to the vehicle status holding unit 36 is updated to the latest information at a constant cycle, the obstacle detected by the obstacle sensor 72 is eliminated within the set time of the timer T1, and the obstacle sensor detects the obstacle. If no more are detected, the obstacle signal input to the vehicle status holding unit 36 is cleared, and NO is determined in step S1304.
[0050]
When it is determined that the obstacle signal from the obstacle sensor 72 is not input to the vehicle state holding unit 36 (step S1301: NO), the door drive motor 41 and the clutch 42 are driven to automatically open the door 52. Is started (S1305). When the door drive motor 41 and the clutch 42 are driven, it is determined whether or not the obstacle signal detected by the sensor detection signal detection unit 27 is input to the vehicle state holding unit 36 (step S1306). If it is determined that the obstacle signal is input to the vehicle status holding unit 36 (step S1306: YES), the process proceeds to step S1309, and the drive of the door drive motor 41 and the clutch 42 is stopped (step S1309). ), The process is terminated.
[0051]
When it is determined that the obstacle signal from the obstacle sensor 72 is not input to the vehicle state holding unit 36 (step S1306: NO), the door position is set to a preset value (for example, 60 degrees of opening) or more. It is determined whether or not (step S1307). When it is determined that the door position is not equal to or greater than the set value (step S1307: NO),
It is determined whether or not there is an inner SW operation (step S1308). If it is determined that there is no inside SW operation (step S1308: NO), the process returns to step S1306, and it is determined whether or not an obstacle signal is input to the vehicle status holding unit 36 (step S1306). If it is determined that the door position is greater than or equal to the set value (step S1307: YES), the drive of the door drive motor 41 and the clutch 42 is stopped (step S1309), and the process ends. That is, the obstacle sensor 72 is always in a period from when the door drive motor 41 and the clutch 42 are driven to start the automatic door opening until the opening degree of the door 52 reaches a set value and the automatic door opening ends. The presence or absence of obstacle detection is monitored.
[0052]
If it is determined that there is an inside SW operation (step S1308: YES), the process proceeds from I in FIG. 13 to step S1601 through I in FIG. 16, and the door drive motor 41 and the clutch 42 are stopped (step S1601). ). Next, it is determined whether or not the current outside opening / closing signal is HIGH (step S1602). When the outside open / close signal is HIGH (step S1602: YES), that is, when the door 52 is automatically opened / closed by a command from the outside SW, the outside open / close signal is set LOW (step S1603), The process ends. If the current outside opening / closing signal is not HIGH (step S1602: NO), that is, if the door 52 is automatically opened / closed by a command from the inside SW, the process is terminated.
That is, when the door 52 is automatically opened / closed by a command from the outside SW, if the inside SW is operated, the automatic opening / closing operation of the door 52 is immediately stopped, and the operation of the inside SW performed later is performed. Prioritize.
Further, in the present embodiment, when the door 52 is automatically opened / closed by a command from the inner SW, assuming that the operation of the rear inner SW reflects the latest intention of the passenger, When the inner SW is operated, the automatic opening / closing operation of the door 52 currently performed is stopped, and the operation of the inner SW performed later is prioritized. However, when the door 52 is automatically opened / closed by a command from the inner SW, when the inner SW is operated, the automatic door opening / closing operation that is being performed is continued in consideration of the convenience of passengers. You may comprise as follows.
[0053]
Next, details of the door closing process in step S1110 in FIG. 11 and step S1206 in FIG. 12 will be described with reference to FIGS.
First, it is determined whether or not a pinching signal detected by the pinching sensor 73 of the vehicle state detection unit 70 and detected by the sensor detection signal detection unit 27 is input to the vehicle state holding unit 36 (step S1401). When the pinching signal is input to the vehicle state holding unit (step S1401: YES), the timer T2 is started (S1402), and it is determined whether the timer T2 is equal to or greater than a set value (step S1403). Next, when the timer T2 is equal to or greater than the set value (step S1403: YES), it is determined that the sandwiched object has not been excluded, and the process ends. When the timer T2 is smaller than the set value (step S1403: NO), it is determined again whether or not the pinching signal has been input to the vehicle state holding unit 36 (step S1404). If it is determined that the pinch signal is still being input to the vehicle status holding unit 36 (step S1404: YES), the process returns to step S1403 to determine whether the timer T2 is equal to or greater than the set value (step S1403). . If it is determined that the pinching signal has not been input to the vehicle status holding unit 36 at that time (step S1404: NO), the process proceeds to step S1405 via J to determine whether the door position is in the half-door state. Determination is made (step S1405). That is, in steps S1402 to S1404, whether or not the detected sandwiched object is eliminated is monitored within the time set in the timer T2 (for example, 3.0 seconds). Since the data input to the vehicle status holding unit 36 is updated to the latest information at a constant cycle, the pinched object detected by the pinch sensor is eliminated within the set time of the timer T2, and the pinch sensor no longer detects the pinched object. If this happens, the pinching signal input to the vehicle status holding unit is cleared, and NO is determined in step S1404.
[0054]
When it is determined that the pinching signal from the pinching sensor 73 has not been input to the vehicle state holding unit 36 (step S1401: NO), it is determined whether or not the door position is a half-door state (step S1405). The half door state means a half latch state. In the present embodiment, after the door 52 is closed to the half-door state, the door 52 is pulled to the fully closed position by the door closer mechanism to completely close the door, thereby reducing the impact at the time of closing. The closer mechanism is a mechanism for automatically closing the door 52 by driving a closer motor (not shown) when it is detected that the door 52 is in a half-door state, and a known closer mechanism is used. . This closer motor may be used in combination with the door drive motor 41. A half door, that is, a half latch state, may be detected by a known detection means such as a limit switch, or in a state where a door full close signal detected by a door open / close state detection sensor (not shown) is not detected, When the door opening detected by the encoder 22 is 0, it may be determined that the door is a half door. If it is determined that the door is in the half-door state (step S1405: NO), the process proceeds from step K1 in FIG. 14 to step S1412 through step K in FIG. 15, and the closer motor is driven (step S1412). . If it is determined that the door 52 is not in a half-door state, that is, is in an open state (step S1405: YES), the door drive motor 41 and the clutch 42 are driven to start automatic door closing (S1406). .
[0055]
When the door drive motor 41 and the clutch 42 are driven, whether or not the pinching signal detected by the pinching sensor 73 of the vehicle state detection unit 70 and detected by the sensor detection signal detection unit is input to the vehicle state holding unit 36 is determined. Is determined (step S1407). If it is determined that the pinching signal has been input to the vehicle state holding unit 36 (step S1407: YES), the process proceeds to step S1410, and the door drive motor and the clutch are stopped (step S1410). Next, the process ends.
[0056]
If it is determined that the pinching signal from the pinching sensor 73 has not been input to the vehicle state holding unit 36 (step S1407: NO), it is determined whether or not the door position is a half-door state (step S1408). If it is determined that the door position has not reached the half-door state (step S1408: NO), it is determined whether or not there is an inside SW operation (step S1409). If it is determined that there is no inside SW operation (step S1409: NO), the process returns to step S1407, and it is determined whether or not a pinching signal has been input to the vehicle state holding unit 36 (step S1407). If it is determined that the door position has reached the half-door state (step S1408: YES), the drive of the door drive motor 41 and the clutch 42 is stopped (step S1411). That is, the presence or absence of the pinching sensor 73 is constantly monitored from when the door driving motor 41 and the clutch 42 are driven to start the automatic door closing until the door 52 reaches the half door state. It becomes.
If it is determined that there is an inside SW operation, the process proceeds to I in FIG. 16 through I in FIG. 14, and stops the door drive motor 41 and the clutch 42 (step S1601). Since the subsequent description is the same as the process of FIG. 16 described in the section of the door opening process, the description is omitted.
[0057]
When the drive of the door drive motor 41 and the clutch 42 is stopped in step S1411, the process proceeds from K in FIG. 14 to K in FIG. 15, the closer motor is driven (step S1412), and the closer is operated (step S1413). Next, it is determined whether the door position is fully closed (step S1414). If it is determined that the door position is not fully closed (step S1414: NO), the process returns to step S1414, and it is determined whether the door position is fully closed (step S1414). That is, the operation of the closer is continued until the door position is fully closed. If it is determined that the door position is fully closed (step S1414: YES), the closer is stopped (step S1415), the closer motor is stopped (step S1416), and the process is terminated.
[0058]
That is, in the series of controls in the present embodiment, when the operation of the inner SW 15 is detected while the automatic door opening / closing by the outer opening / closing signal is being performed, the operation by the outer opening / closing signal is immediately stopped. The processing by the inner SW 15 is performed. In addition, when the operation of the inner SW 15 is detected while the automatic door opening / closing by the inner opening / closing signal is being performed, the operation currently in progress is immediately stopped, and the processing by the inner SW 15 operated later is performed. carry out. This is because when there is a conflict between the operation command by the inner SW and the operation command by the outer SW, the operation by the outer SW is likely to be an operation unintended by the passenger and an operation not desired by the passenger. This is to prioritize the directive. In addition, when the operation command by the inner SW 15 overlaps with the time difference, it is considered that the latest operation is more likely to clearly reflect the intention of the passenger, so the subsequent switch operation It is effective.
[0059]
As described above, according to the present embodiment, the following effects are obtained.
(A) In the vehicle door opening and closing device S of the present embodiment, as described above, when the inner SW 15 and the outer SW 16 are operated at the same time, and during the automatic door opening and closing by the command of the inner SW 15, the operation of the outer SW 16 is performed. If it is, the operation of the outside SW 16 is invalidated. Further, when the inner SW 15 is operated during the automatic door opening / closing by the command of the inner SW 15 and during the automatic door opening / closing by the command of the outer SW 16, the operation currently being executed is stopped and the operation of the inner SW is given priority. For this reason, it becomes possible to prevent the automatic opening / closing operation of the door 52 unintended by the passenger and the automatic opening / closing operation of the door 52 not desired by the passenger by the operation of the outside SW. That is, since the outside SW 16 is disposed outside the vehicle, there is a possibility that the outside SW 16 will be pressed by contact with the belongings of another person outside the vehicle, and the automatic opening / closing operation of the door 52 that is not desired by the outside person. It is assumed that Even in such a case, in the vehicle door opening and closing apparatus S of the present embodiment, the operation of the inner SW 15 is prioritized, so that convenience for passengers is improved. Further, when the operation of the inner SW 15 is further performed during the automatic door opening / closing by the command of the inner SW 15, the later operation is prioritized, so that the latest intentions of the passengers are reflected. Is possible. That is, the door automatic opening process is commanded from the inside SW, but in the case of any emergency state, when switching to the door automatic closing process is desired during the automatic door opening operation, the subsequent operation is prioritized, so passenger convenience is improved. To do.
[0060]
(B) In the vehicle door opening and closing apparatus S of the present embodiment, the vehicle state detection unit 70 includes a vehicle speed sensor 71, an obstacle sensor 72, and a pinching sensor 73, and monitors the vehicle state.
