Description

The present invention relates to an opening / closing body control device and a program.

As the opening / closing body control device, for example, the following are known (see, for example, Patent Document 1). That is, in a known opening / closing body control device, the motor current at each moving position of the front side glass of the vehicle is detected, and the pinching of the front side glass is determined by comparing the motor current with the threshold value.

Here, for example, when the glass run or the glass weather strip sliding with the front side glass changes over time, the sliding resistance acting on the front side glass changes, and the motor current for each moving position of the front side glass also changes accordingly. As described above, when the motor current for each moving position of the front side glass changes due to secular variation or the like, if the threshold value remains constant, there is a possibility that the pinching of the front side glass cannot be correctly determined.

Therefore, in a known opening / closing body control device, every time the front side glass rises, the motor current for each moving position of the front side glass is detected as a learning value, and a correction value is added to this learning value to set a threshold value for pinch detection. is doing.

Further, in this known opening / closing body control device, in the case of a sashless hardtop vehicle, the sliding resistance acting on the front side glass differs between the open state and the closed state of the front door, and the front door is opened. Two types of correction values are available, one for the state and one for the closed state. Then, by adding this correction value to the learning value, two types of pinch detection thresholds, one for the open state and the other for the closed state of the front door, are set.

Subsequently, in the abnormality determination process, the open / closed state of each of the roof 30 and the rear quarter glass 34 is determined, and the learning value corresponding to the determination result is extracted from the RAM 44. Then, the motor rotation speed of the motor drive unit 20 that raises the front side glass 32 is detected as a detection value for each movement position of the front side glass 32, and is calculated based on the above-extracted learning value and a predetermined correction value. The result of comparing the determined threshold value with the detected value is output as the sandwiching determination result.

Therefore, since the sandwiching determination is performed based on the learning values stored in association with the open / closed states of the roof 30 and the rear quarter glass 34, the front side glass 32 is affected by the open / closed states of the roof 30 and the rear quarter glass 34.

That is, when it is determined that the roof 30 is in the closed state and the rear quarter glass 34 is in the closed state, the CPU 40 (correction value selection unit 164) of the power window ECU 16 in the FR seat executes step S54-1. Then, the CPU 40 (correction value selection unit 164) selects the first correction value stored in advance in the ROM 42 in association with the closed state of the roof 30 and the closed state of the rear quarter glass 34.

When it is determined that the roof 30 is closed and the rear quarter glass 34 is open, the CPU 40 (correction value selection unit 164) of the power window ECU 16 in the FR seat executes step S54-2. Then, the CPU 40 (correction value selection unit 164) selects a second correction value stored in advance in the ROM 42 in association with the closed state of the roof 30 and the open state of the rear quarter glass 34.

When it is determined that the roof 30 is in the open state and the rear quarter glass 34 is in the closed state, the CPU 40 (correction value selection unit 164) of the power window ECU 16 in the FR seat executes step S54-3.

At this time, when the detected value is equal to or higher than the threshold value, the CPU 40 (abnormality determination result output unit 166) of the power window ECU 16 in the FR seat outputs the pinching determination result without pinching. On the other hand, when the detected value is less than the threshold value, the CPU 40 (abnormality determination result output unit 166) outputs the pinching determination result indicating that there is pinching.

When the pinching determination result indicating that there is pinching is output by the CPU 40 (abnormality determination result output unit 166), the power window ECU 16 in the FR seat reverses the motor drive unit 20 in the FR seat.

That is, in step S71-1 (open / close state acquisition process), the open / closed state of the roof 30 is acquired, and in step S71-2 (open / close state acquisition process), the open / closed state of the rear quarter glass 34 is acquired. Further, in step S72 (operation determination processing), the operating state of the power window ECU 16 in the FR seat is determined, and in step S73 (opening / closing state determination processing), the open / closed state of each of the roof 30 and the rear quarter glass 34 is determined. ..

(Step S74 of entanglement determination process: correction value selection process)
Step S74 is different from step S34 in the first embodiment described above. In this step S74, the CPU 40 (correction value selection unit 164) of the power window ECU 16 in the FR seat sets the correction value stored in advance in the ROM 42 in association with the open / closed states of the roof 30 and the rear quarter glass 34 in the above-mentioned step. Select according to the determination result of S73.

That is, when it is determined that the roof 30 is in the closed state and the rear quarter glass 34 is in the closed state, the CPU 40 (correction value selection unit 164) of the power window ECU 16 in the FR seat executes step S74-1. Then, the CPU 40 (correction value selection unit 164) selects the first correction value stored in advance in the ROM 42 in association with the closed state of the roof 30 and the closed state of the rear quarter glass 34.

When it is determined that the roof 30 is closed and the rear quarter glass 34 is open, the CPU 40 (correction value selection unit 164) of the power window ECU 16 in the FR seat executes step S74-2. Then, the CPU 40 (correction value selection unit 164) selects a second correction value stored in advance in the ROM 42 in association with the closed state of the roof 30 and the open state of the rear quarter glass 34.

When it is determined that the roof 30 is in the open state and the rear quarter glass 34 is in the closed state, the CPU 40 (correction value selection unit 164) of the power window ECU 16 in the FR seat executes step S74-3. Then, the CPU 40 (correction value selection unit 164) selects a third correction value stored in advance in the ROM 42 in association with the open state of the roof 30 and the closed state of the rear quarter glass 34.

When it is determined that the roof 30 is in the open state and the rear quarter glass 34 is in the open state, the CPU 40 (correction value selection unit 164) of the power window ECU 16 in the FR seat executes step S74-4. Then, the CPU 40 (correction value selection unit 164) selects a fourth correction value stored in advance in the ROM 42 in association with the open state of the roof 30 and the open state of the rear quarter glass 34. The above-mentioned first to fourth correction values are arbitrary values determined for detecting entrainment.

(Step S75 of entrainment determination process: threshold value calculation process)
Step S75 is different from step S35 in the first embodiment described above. In this step S75, the CPU 40 (threshold value calculation unit 165) of the power window ECU 16 in the FR seat determines the front side glass 32 based on the learning value stored in the above step S65 and the correction value selected in the above step S74. Calculate the threshold value for each moving position. That is, the CPU 40 (threshold value calculation unit 165) is a motor rotation speed which is a correction value selected in the above step S74 from the motor rotation speed as a learning value when both the roof 30 and the rear quarter glass 34 are in the closed state. Calculate the threshold by subtracting the speed.

(Step S76 of entrainment determination processing: Abnormality determination result output processing)
Step S76 is the same as step S36 in the above-mentioned first embodiment. In this step S76, the CPU 40 (abnormality determination result output unit 166) of the power window ECU 16 in the FR seat determines the motor rotation speed based on the signal output from the motor drive unit 20 in the FR seat for each movement position on the front side glass 32. Is detected as a detection value. This motor rotation speed corresponds to the moving speed of the front side glass 32, and corresponds to the "detection value according to the moving speed of the third opening / closing body".

Then, the CPU 40 (abnormality determination result output unit 166) compares the threshold value calculated in the above step S75 with the detected value, and outputs the comparison result as the involvement determination result (abnormality determination result). At this time, when the detected value is equal to or higher than the threshold value, the CPU 40 (abnormality determination result output unit 166) of the power window ECU 16 in the FR seat outputs the entrainment determination result that there is no entrainment. On the other hand, when the detected value is less than the threshold value, the CPU 40 (abnormality determination result output unit 166) outputs an entrainment determination result indicating that there is entrainment.

When the CPU 40 (abnormality determination result output unit 166) outputs an entrainment determination result indicating that there is entrainment, the power window ECU 16 in the FR seat stops the motor drive unit 20 in the FR seat. As a result, the front side glass 32 is stopped and entrainment is prevented.

(Action effect)
As described in detail above, according to the open / close body control device 110 according to the second embodiment, in the learning value storage process, the open / closed states of the roof 30 and the rear quarter glass 34 are acquired. Further, the motor rotation speed of the motor drive unit 20 for lowering the front side glass 32 is acquired as a learning value for each movement position of the front side glass 32. Then, among the acquired learning values, the learning values when the opening / closing state of each of the roof 30 and the rear quarter glass 34 is a predetermined opening / closing state are stored in the RAM 44.

Subsequently, in the abnormality determination process, the open / closed state of each of the roof 30 and the rear quarter glass 34 is determined, and the correction value stored in advance in the ROM 42 in association with the open / closed state of each of the roof 30 and the rear quarter glass 34 is described above. It is selected according to the judgment result. Then, the motor rotation speed of the motor drive unit 20 that lowers the front side glass 32 is detected as a detection value for each movement position of the front side glass 32, and is based on the learning value stored in the RAM 44 and the selected correction value. The result of comparing the calculated threshold value with the detected value is output as the entrainment determination result.

Therefore, since the entrainment determination is performed based on the learning value corrected by the correction value stored in association with the open / closed state of each of the roof 30 and the rear quarter glass 34, the open / closed state of each of the roof 30 and the rear quarter glass 34 is performed. Even when the sliding resistance acting on the front side glass 32 changes, it is possible to make an appropriate entrainment determination for the front side glass 32 according to the open / closed state of each of the roof 30 and the rear quarter glass 34.

(Other operations in this example)
In this example, as an example, the entanglement when the front side glass 32 of the FR seat is lowered is detected, but the same applies to the case of detecting the entanglement when the front side glass 32 of the FL seat is lowered. In this case, the roof 30 corresponds to the "first opening / closing body", the rear quarter glass 34 of the RL seat corresponds to the "second opening / closing body", and the front side glass 32 of the FL seat corresponds to the "third opening / closing body". Corresponds to.

Further, the same applies to the case of detecting the entrainment when the rear quarter glass 34 of the RR seat or the RL seat is lowered. In this case, the roof 30 corresponds to the "first opening / closing body", the front side glass 32 of the FR seat or the FL seat corresponds to the "second opening / closing body", and the rear quarter glass 34 of the RR seat or the RL seat corresponds to the rear quarter glass 34. Corresponds to the "third opening and closing body". Further, in this case, in FIGS. 16 and 17, the “target glass” is the rear quarter glass 34 of the RR seat or the RL seat, and the “glass adjacent to the front and rear” is the front side glass of the FR seat or the FL seat. 32.

If so, the correction value (1) is selected from the table. No. of this table. In No. 1, since the roof 30 and the rear quarter glass 34 are both in the closed state and the open / closed state does not change between the pinch learning value storage process and the pinch determination process, there is no need to perform correction. Therefore, the correction value (1) is a correction value of 0 as an example.

There is. Therefore, the correction value (3) is a correction value that absorbs such a difference.

In addition, the table NO.

This motor rotation speed corresponds to the moving speed of the front side glass 32, and corresponds to the "detection value according to the moving speed of the third opening / closing body".

Then, the CPU 40 (abnormality determination result output unit 266) compares the threshold value calculated in step S94 with the detected value, and outputs the comparison result as a sandwiching determination result (abnormality determination result). At this time, when the detected value is equal to or higher than the threshold value, the CPU 40 (abnormality determination result output unit 266) of the power window ECU 16 in the FR seat outputs the pinching determination result without pinching. On the other hand, when the detected value is less than the threshold value, the CPU 40 (abnormality determination result output unit 266) outputs the pinching determination result indicating that there is pinching.

When the pinching determination result indicating that there is pinching is output by the CPU 40 (abnormality determination result output unit 266), the power window ECU 16 in the FR seat reverses the motor drive unit 20 in the FR seat. As a result, the front side glass 32 is lowered to prevent pinching.

Subsequently, the open / closed states of the roof 30 and the rear quarter glass 34 are acquired during the pinch determination process. Further, from the combination of the open / closed states of the roof 30 and the rear quarter glass 34 stored in the RAM 44 during the pinch learning value storage process and the open / closed states of the roof 30 and the rear quarter glass 34 acquired during the pinch determination process. , The correction value is selected from the preset table. Then, the motor rotation speed of the motor drive unit 20 that raises the front side glass 32 is detected as a detection value for each movement position of the front side glass 32, and is based on the learning value stored in the RAM 44 and the selected correction value. The result of comparing the calculated threshold value with the detected value is output as the sandwiching determination result.

Therefore, it corresponds to the open / closed state of each of the roof 30 and the rear quarter glass 34 stored in the RAM 44 during the pinch learning value storage process, and the open / closed state of each of the roof 30 and the rear quarter glass 34 acquired during the pinch determination process. Since the pinching determination is performed based on the learning value corrected by the correction value, even if the sliding resistance acting on the front side glass 32 changes depending on the open / closed state of each of the roof 30 and the rear quarter glass 34, the front side glass 32 Appropriate pinching determination can be made according to the open / closed state of each of the roof 30 and the rear quarter glass 34.

Need to be corrected. Therefore, the correction value (4) is a correction value that absorbs such a difference.

In addition, the table No. 5 ~ NO. The contents of No. 16 will be omitted, but the table No. 5 ~ NO. Also in 16, correction values set according to the open / closed state of the roof 30 and the rear quarter glass 34 during the entrainment learning value storage process and the open / closed state of the roof 30 and the rear quarter glass 34 during the entrainment determination process are selected. The glass.

(Step S114 of entanglement determination process: threshold value calculation process)
Step S114 is different from step S35 in the first embodiment described above. In this step S114, the CPU 40 (threshold value calculation unit 265) of the power window ECU 16 in the FR seat of the front side glass 32 is based on the learning value stored in the above-mentioned step S104 and the correction value selected in the above-mentioned step S113. Calculate the threshold value for each moving position. That is, the CPU 40 (threshold value calculation unit 265) calculates the threshold value by adding or subtracting the selected correction value of the motor rotation speed from the motor rotation speed which is the learning value for each moving position on the front side glass 32.

(Step S115 of entrainment determination processing: abnormality determination result output processing)
Step S115 is the same as step S36 in the above-mentioned first embodiment. In this step S115, the CPU 40 (abnormality determination result output unit 266) of the power window ECU 16 in the FR seat has a motor rotation speed based on a signal output from the motor drive unit 20 in the FR seat for each movement position on the front side glass 32. Is detected as a detection value. This motor rotation speed corresponds to the moving speed of the front side glass 32, and corresponds to the "detection value according to the moving speed of the third opening / closing body".

Then, the CPU 40 (abnormality determination result output unit 266) compares the threshold value calculated in step S114 described above with the detected value, and outputs the comparison result as a involvement determination result (abnormality determination result). At this time, when the detected value is equal to or higher than the threshold value, the CPU 40 (abnormality determination result output unit 266) of the power window ECU 16 in the FR seat outputs the entrainment determination result that there is no entrainment. On the other hand, when the detected value is less than the threshold value, the CPU 40 (abnormality determination result output unit 266) outputs an entrainment determination result indicating that there is entrainment.

When the CPU 40 (abnormality determination result output unit 266) outputs an entrainment determination result indicating that there is entrainment, the power window ECU 16 in the FR seat stops the motor drive unit 20 in the FR seat. As a result, the front side glass 32 is stopped and entrainment is prevented.

(Action effect)
As described in detail above, according to the open / close body control device 210 according to the third embodiment, the open / closed states of the roof 30 and the rear quarter glass 34 are acquired at the time of the entrainment learning value storage process. Further, the motor rotation speed of the motor drive unit 20 for lowering the front side glass 32 is acquired as a learning value for each movement position of the front side glass 32. Then, the open / closed state of each of the acquired roof 30 and the rear quarter glass 34 and the learning value are stored in the RAM 44.

Subsequently, the open / closed states of the roof 30 and the rear quarter glass 34 are acquired during the entrainment determination process. Further, from the combination of the open / closed states of the roof 30 and the rear quarter glass 34 stored in the RAM 44 during the entrainment learning value storage process and the open / closed states of the roof 30 and the rear quarter glass 34 acquired during the entrainment determination process. , The correction value is selected from the preset table. Then, the motor rotation speed of the motor drive unit 20 that lowers the front side glass 32 is detected as a detection value for each movement position of the front side glass 32, and is based on the learning value stored in the RAM 44 and the selected correction value. The result of comparing the calculated threshold value with the detected value is output as the entrainment determination result.

Therefore, it corresponds to the open / closed state of each of the roof 30 and the rear quarter glass 34 stored in the RAM 44 during the entrainment learning value storage process, and the open / closed state of each of the roof 30 and the rear quarter glass 34 acquired during the entrainment determination process. Since the entrainment determination is performed based on the learning value corrected by the correction value, even if the sliding resistance acting on the front side glass 32 changes depending on the open / closed state of each of the roof 30 and the rear quarter glass 34, the front side glass 32 Appropriate entrainment determination can be made according to the open / closed state of each of the roof 30 and the rear quarter glass 34.

(Other operations in this example)
In this example, as an example, the entanglement when the front side glass 32 of the FR seat is lowered is detected, but the same applies to the case of detecting the entanglement when the front side glass 32 of the FL seat is lowered. In this case, the roof 30 corresponds to the "first opening / closing body", the rear quarter glass 34 of the RL seat corresponds to the "second opening / closing body", and the front side glass 32 of the FL seat corresponds to the "third opening / closing body". Corresponds to.

Further, the same applies to the case of detecting the entrainment when the rear quarter glass 34 of the RR seat or the RL seat is lowered. In this case, the roof 30 corresponds to the "first opening / closing body", the front side glass 32 of the FR seat or the FL seat corresponds to the "second opening / closing body", and the rear quarter glass 34 of the RR seat or the RL seat corresponds to the rear quarter glass 34. Corresponds to the "third opening and closing body". Further, in this case, in FIGS. 16 and 17, the “target glass” is the rear quarter glass 34 of the RR seat or the RL seat, and the “glass adjacent to the front and rear” is the front side glass of the FR seat or the FL seat. 32.

Next, a modification common to the above-mentioned first to third embodiments will be described.

In the pinch determination process in the first to third embodiments, the motor rotation speed for each moving position on the front side glass 32 is acquired as a learning value, and the correction value is subtracted from this learning value to calculate the threshold value. When the motor rotation speed, which is the detected value for each moving position on the front side glass 32, is equal to or greater than the threshold value, it is determined that there is no pinching, and when the detected value is less than the threshold value, it is determined that there is pinching.

However, for example, the moving speed for each moving position on the front side glass 32 may be acquired as a learning value, and the threshold value may be calculated by subtracting the correction value from this learning value. When the moving speed, which is the detected value for each moving position on the front side glass 32, is equal to or higher than the threshold value, it may be determined that there is no pinching, and when the detected value is less than the threshold value, it may be determined that there is pinching.

Further, for example, the motor current (or motor voltage) for each moving position on the front side glass 32 may be acquired as a learning value, and a correction value may be added to this learning value to calculate a threshold value. If the motor current (or motor voltage), which is the detected value for each moving position on the front side glass 32, is less than the threshold value, it is determined that there is no pinching, and if the detected value is greater than or equal to the threshold value, it is determined that there is pinching. good.

Further, in the entrainment determination processing in the first to third embodiments, the motor rotation speed for each moving position on the front side glass 32 is acquired as a learning value, and the correction value is subtracted from this learning value to calculate the threshold value. When the motor rotation speed, which is the detected value for each moving position on the front side glass 32, is equal to or higher than the threshold value, it is determined that there is no entrainment, and when the detected value is less than the threshold value, it is determined that there is entrainment.

However, for example, the moving speed for each moving position on the front side glass 32 may be acquired as a learning value, and the threshold value may be calculated by subtracting the correction value from this learning value. When the moving speed, which is the detected value for each moving position on the front side glass 32, is equal to or higher than the threshold value, it may be determined that there is no entrainment, and when the detected value is less than the threshold value, it may be determined that there is entrainment.

Further, for example, the motor current (or motor voltage) for each moving position on the front side glass 32 may be acquired as a learning value, and a correction value may be added to this learning value to calculate a threshold value. If the motor current (or motor voltage), which is the detected value for each moving position on the front side glass 32, is less than the threshold value, it is determined that there is no entrainment, and if the detected value is greater than or equal to the threshold value, it is determined that there is entrainment. good.

Further, in the above embodiment, the opening / closing body control device 10 is applied to a vehicle, but may be suitable for a vehicle or the like other than the vehicle.

Further, in the above embodiment, each functional unit such as the learning value storage processing unit 50 in each power window ECU 16 is realized by the CPU 40 executing the program 46 (or the program 146). However, each functional unit such as the learning value storage processing unit 50 may be realized by a PLD (Programmable Logic Device) whose circuit configuration can be changed after manufacturing, such as FPGA (Field-Programmable Gate Array).
