Description

  The present invention relates to a control device for a retractable roof for a vehicle, and more particularly to a control device for a retractable roof for a vehicle that electrically opens and closes the roof.

  Some vehicles are provided with a roof control device (roof opening / closing control system) having a roof drive mechanism for opening and closing the roof. In this case, the roof is divided into two parts, a roof front part and a roof rear part, and the two divided roofs are mechanically connected and housed in a trunk by a synchronized operation.

Conventionally, in a roof structure of a vehicle, a roof front portion and a roof rear portion constituting the roof are pivotally attached to a vehicle body by vehicle body side mounting portions, and the vehicle body side mounting portion is connected to one driving means via a link mechanism. In some cases, the roof front part and the roof rear part are merely pivoted so that the roof front part and the roof rear part are positioned in either the closed position or the open position.
JP, 5-63326, A In addition, the roof opening and closing device of a vehicle is provided with position recognition means for detecting the position of a swingable structural element that supports the roof and the rotatable tonneau cover. There is one that moves the structural element and the tonneau cover at the same time while accurately detecting the relative position of the element and the tonneau cover. Japanese Patent No. 3284138

  By the way, in the conventional vehicle roof control device, when the vehicle roof is divided into two parts, each roof is operated separately, and the roof is stored in the vertical direction with respect to the ground, the roof is in the middle of storage. There is a risk of contact with each other. This is because the arms of the roofs installed side by side move in a circular arc with a place connected to the vehicle body as a fulcrum and pass on each other's locus.

  However, if the rear roof in the two divided roofs is tilted to a position substantially parallel to the ground, the front roof can be accommodated without contacting. In that case, in order for the front roof to be stored in a form hidden completely behind the rear roof, it is necessary that the front roof is operable beyond the maximum angle reached by the rear roof.

  Here, in order to securely store the roof without contacting the front roof and the rear roof, it is only necessary to control the operation so that the rear roof is stored first and then the front roof is stored. It takes time to open and close the operation of the rear roof and the operation completion time of the front roof, and a gap between the roofs is greatly opened during the opening and closing of the roof. .

  Therefore, in order to open and close the roof while reducing the gap between the roofs as much as possible in order to shorten the opening and closing time without reducing the contact between the roofs and to reduce the amount of foreign matter being caught, the detecting means for detecting the position of the roof on each roof It is necessary to control the operation of the roof while maintaining the positional relationship between the roofs. In that case, it is optimal if a detection means that can detect the position of the roof at all angles is attached, such as a detection means that detects the accelerator opening, but it is difficult to attach the detection means or the cost increases. There was an inconvenience.

  For this reason, if the detection means (microswitch etc.) which detects only the position vicinity of the position where roofs contact is used, a system can be comprised simply and cheaply. When the rear roof is stopped at a certain location and the front roof is retracted and retracted, the position where the front roof contacts the rear roof during the roof open control and the front during the close control It is necessary to detect the position where the roof of the vehicle is completely separated from the rear roof, but the positions are different. Therefore, it is necessary for the detection means of one roof to have a specification capable of detecting two points, which has the disadvantage that the specification of the detection means becomes complicated and the number of detection means increases.

  SUMMARY OF THE INVENTION An object of the present invention is to provide a retractable roof for a vehicle that contributes to improving the merchantability of a retractable roof system by operating each divided roof independently at an appropriate timing to shorten the opening and closing time of the roof. It is to provide a control device.

  When the rear second position sensor 44 is turned off (time t5), the front angle sensor 45 is turned off (time t6), and when the rear angle sensor 46 is turned on (time t7), the rear second relay 26 Is turned off.

  Thereafter, when a predetermined time T2 has elapsed from time t3 (time t8), the rear second relay 26 is turned on. The fixed time T2 is a time (for example, 5 seconds) corresponding to the time between the front angle of 85 degrees and 35 degrees that is the angle of the roof front portion 6, and is normally constant. It can be set without using a switch to detect. Further, the fixed time T2 is set longer than usual because the time of the roof operation is delayed due to the hardening of the hydraulic viscosity at a low temperature and the decrease in the motor rotation speed at a low battery voltage.

  When the rear angle sensor 46 is turned off (time t9), the front first position sensor 41 is turned on (time t10), and when a certain time T3 has elapsed from this time (time t10) (time t11), The front second relay 19 is turned off. The fixed time T3 is a time (for example, 1 second) for correcting the detection position of each sensor 41, 43 at the upper end of the roof 3 and the actual end position.

  Thereafter, the rear first position sensor 43 is turned on (time t12), and when the predetermined time T4 has elapsed from this time (time t12) (time t13), the rear second relay 26 is turned off. The predetermined time T4 is a time (for example, 1 second) for correcting the detection positions of the sensors 41 and 43 at the upper end of the roof 3 and the actual end position.

  Thereafter, the close switch 39 is turned off (time t14).

  7 will be described based on the roof operation of FIG.

  As shown in FIG. 8, in the roof open state, the roof front part 6 and the roof rear part 7 are at the lower end, and in the transition to the roof close, first, the roof front part 6 operates first (first Step [1]), and then, after a predetermined time has elapsed, the roof rear portion 7 operates (second step [2]). This is to prevent the roof front portion 6 and the roof rear portion 7 from coming into contact immediately after the operation by operating the roof front portion 6 slightly ahead.

  When the rear angle sensor 46 detects a predetermined angle (rear angle: 50 degrees), only the operation of the roof rear portion 7 is stopped (third step [3]), and then the front angle sensor 45 is moved to the predetermined angle (front The roof front part 6 is operated until an angle (85 degrees to 35 degrees) is detected (fourth control process [4]). In the fourth step [4], the time for the front angle sensor 45 to reach a predetermined angle (front angle: 85 degrees to 35 degrees) is a time for the roof 3 to move substantially by the length of the roof front portion 6. It can be seen as a certain time.

  Thereafter, when the roof front part 6 reaches a predetermined angle (front angle: 35 degrees), the roof front part 6 and the roof rear part 7 are operated simultaneously (fifth step [5]). The uppermost end is reached before the portion 7, and then the roof rear portion 7 reaches the uppermost end (sixth step [6]).

  That is, in this embodiment, when the roof is opened, the front angle for detecting the position of the front angle (85 degrees) of the limit angle at which the roof front section 6 does not contact the roof rear section 7 stopped at the position where the rear angle is 50 degrees. The sensor 45 is provided, and the roof operation when the roof is opened is performed as shown in FIGS. 3 and 4, while the roof operation when the roof is closed is performed as shown in FIGS. 5, 6, 7, and 8.

  At the time of roof open transition, if the operation of the roof rear part 7 is resumed after detecting the position where the front angle is 85 degrees, the roof front part 6 and the roof rear part 7 move together while maintaining the positional relationship. And stored in the space 8 without contact (see FIGS. 3 and 4).

  On the other hand, at the time of shifting to the roof close, it is sufficient to operate so as to follow the reverse process at the time of shifting to the roof open. At the position where the rear angle is around 50 degrees, the front angle is around 85 degrees. The roof front portion 6 has a positional relationship slightly ahead of the roof rear portion 7 (see first to third steps [1] to [3] in FIG. 6).

  The moving distance of the roof 3 from this position to a position at which the roof front part 6 can completely escape from the roof rear part 7 (refer to the front angle (35 degrees) in FIG. 6) is approximately the length of the roof front part 6. If the roof speed is constant, the roof travel time during that time can be sufficiently predicted. If the movement time of the roof 3 is set as the constant time T2 in FIG. 3 and the operation of the roof rear portion 7 is resumed after the fixed time T2 has elapsed after the roof front portion 6 has detected the position of the front angle (85 degrees). The roof front part 6 can be in a closed state without being caught up with the roof rear part 7 (see the fourth to sixth steps [4] to [6] in FIG. 8).

  The movement time of the roof 3 may vary depending on the battery voltage and temperature in the open / close control means 13, and must be set longer than at normal temperature when the voltage is low or low. This is because the roof operation may not be stable due to a decrease in the number of rotations of the motor when the voltage is low, and due to the curing of the viscosity when the temperature is low.

  Further, in the above description, an example in which the roof operation direction is the same from the beginning to the end, such as from the roof open state to the roof closed state or from the roof closed state to the roof open state, has been described. In this case, the roof front part 6 and the roof rear part 7 must be operated without contacting each other. When the roof is reversed in the open direction during the closing, there is no problem even if the roof is reversed at any position as long as the sensor is configured as described above. This is because there is a sensor that can detect a position immediately before the roof front portion 6 and the roof rear portion 7 come into contact with each other when the door is open.

  However, in the case of reversing in the closing direction from the middle of opening, the above control method (control method for restarting the roof rear portion 7 after the roof front portion 6 detects the position of the front angle (85 degrees) and after a predetermined time has elapsed). ) Alone may not be possible. This is a case where the roof front portion 6 is reversed in the closing direction when it is between the front angle (35 degrees) position and the front angle (85 degrees) position. In this case, the front angle (85 degrees) Therefore, the fixed time T2 for resuming the operation of the roof rear portion 7 cannot be measured (see FIG. 7).

  In this case, it can be dealt with by memorizing the time when the roof rear part 7 is stopped during the opening, and operating the roof rear part 7 after the time has elapsed after reversing. This is because there is a gap between the roof front part 6 and the roof rear part 7 because the roof rear part 7 precedes the roof front part 6 before the open roof rear part 7 stops. The amount of clogging before is related to the stop time of the roof rear portion 7.

  When reversing to the closed position, it is sufficient to stop the roof rear section 7 for the amount of time that the jam occurs and separate the roof front section 6 from the roof rear section 7. Therefore, the closed reversal is performed only for the time the roof rear section 7 stops during opening. After that, the roof rear portion 7 may be stopped (see FIG. 7).

  In this embodiment, the front angle sensor 45 that detects the position of the roof front portion 6 is a switch that detects a limit position that does not contact the roof rear portion 7 during opening. You may use the switch which detects the position where the part 6 escapes from the roof rear part 7. FIG. In this case, a method similar to the control method during closing described above may be performed during opening. That is, after the detection by the front angle sensor 45, the operation of the roof rear portion 7 is resumed after a predetermined time has elapsed. Therefore, if such a control method is used, the opening / closing control of the roof can be performed with one of the switches without separately preparing a switch for detecting the position of one roof for opening and closing. Is possible.

  Therefore, in a configuration in which each roof is provided with a sensor for detecting the roof position, when either the opening operation or the closing operation is performed, the roof rear portion 7 is temporarily stopped at the detection position of the sensor, and the roof front portion 6 is moved to the sensor. It is possible to restart the operation of the roof rear portion 7 after a predetermined time has elapsed since reaching the detection position. As a result, even if there is a positional relationship where the two roofs interfere with each other on the trajectory of the roof operation, the roof front part 6 and the roof rear part 7 are opened and closed without contacting each other, and one roof is completely opened and closed. It is possible to open and close the roof in a shorter time than moving the other, and to reduce the gap between the roofs. Further, the number of position sensors can be controlled by one for each roof.

  Further, in this embodiment, with the above configuration, if each fixed time is varied depending on the temperature and the battery voltage, it is possible to adjust so that the roof front portion 6 and the roof rear portion 7 do not interfere with each other in any state. It becomes. In the above configuration, when the roof operation is reversed before the operation is resumed after the roof rear portion 6 is stopped, the time that the roof rear portion 7 is stopped before the predetermined time is reversed. It is possible to restart the operation of the roof rear portion 7 after a certain period of time has elapsed since the inversion. Thereby, it becomes possible to adjust so that the roof front part 6 and the roof rear part 7 may not interfere in any state.

As a result, the roof 3 includes a roof front portion 6 that covers the front portion of the passenger compartment 5 and a roof rear portion 7 that covers the rear portion of the passenger compartment 5. One end of the roof 3 is connected to the roof front portion 6 and the other end is driven by the roof front. A front arm 14 which is a first connecting member connected to the mechanism 11 is provided, a rear arm 15 which is a second connecting member connected to the roof rear drive mechanism 12 at one end side and connected to the roof rear drive mechanism 12 at one end side is provided. 3 of the opening and closing control means 13 for opening and closing controlled independently a front roof portion 6 and Rufuria section 7 at the time of opening and closing is provided, the opening and closing control means 13, only one of the front roof portion 6 and Rufuri a section 7 and a second switching control unit which opens and closes at the same time both the first switching control section 13A and the front roof portion 6 and Rufuri a section 7 for opening and closing operation, Lou When the operation from the fully closed state 3 to the fully opened state or the roof 3 from the fully opened state to the fully closed state is started, the first opening / closing control unit 13A is used to control first, and after a predetermined time has elapsed, the second opening / closing control unit Control using 13B. Thus, as compared with the case without the opening operation of the other roof until one of the two roof finishes completely open, it is possible to shorten the opening time of the roof. As a result, it is possible to contribute to improving the merchantability of the retractable loop system.

Further, the switching control unit 13 connects the respective positions of the front roof portion 6 and Rufuri A section 7 at the time of opening and closing of the roof 3 to recognize the position recognizing unit 40, recognized front roof in the position recognizing section 40 depending on the respective positions of the parts 6 and Rufuri a unit 7 controls to select either the first on-off control unit 13A and the second switching control section 13B. Thereby, since the opening control part is selected after recognizing the mutual position of the two roofs, the two roofs do not interfere at the time of opening.

  Furthermore, the position recognition means 40 recognizes the upper and lower ends and the rotation angle of each roof 6, 7. As a result, the upper and lower ends of the roof 3 and the rotation angle at the time of opening and closing can be recognized, so that it is possible to realize highly accurate storage control in a short time without interference between the two roofs.

  The position recognition means 40 is a detection means for outputting the same position signal when the roof 3 is opened and closed. As a result, when the roof is opened and when the roof is closed, the opening / closing control can be performed using the same position signal, and it is possible to realize a control system that has a simple configuration and is less likely to fail.

  Therefore, the present invention can achieve the object of operating each divided roof independently at an appropriate timing and contributing to the improvement of the merchantability of the retractable roof system by shortening the opening and closing time of the roof. .

  Independently operating each divided roof at an appropriate timing can be applied not only to the vehicle but also to other structures.
