Description

The present invention relates to a device that controls the opening / closing operation of an electric sliding door.

One-box type and minivan type vehicles have a sliding door that opens and closes by sliding in the front-rear direction on the rear side door, which is standard depending on the option or grade, and the sliding door is opened and closed by the driving force of a motor etc. (electric opening and closing) ), So-called electric sliding door (power sliding door) is equipped. The electric sliding door is convenient because the sliding door automatically opens and closes according to the operation of the door handle. Nevertheless, since the opening / closing speed (moving speed) of the sliding door is slow, many users do not use the electric sliding door by disabling it.

Therefore, when the user desires the quick opening and closing of the electric sliding door, it is desired to increase the opening and closing speed of the sliding door. To meet this need, for example, it has been proposed to increase the opening / closing speed of the sliding door when the user continues to operate the door handle for a predetermined time (see, for example, Patent Document 1).

Japanese Unexamined Patent Publication No. 2013-170395

However, in the technique according to the conventional proposal, if the user has a habit of operating the door handle for a long time even when the user does not intend to open and close the sliding door quickly, the opening and closing speed of the sliding door unexpectedly increases. It may give the user a sense of discomfort.

An object of the present invention is to provide an electric sliding door control device capable of increasing the opening / closing speed of the sliding door according to the intention of the user to open / close the sliding door quickly. ..

In order to achieve the above object, the electric sliding door control device according to the present invention is a device that controls the opening / closing operation of the sliding door by the driving force of the motor based on the operation of the door handle provided on the sliding door of the vehicle. A measuring means for measuring the duration of operation of the door handle, a current value acquiring means for acquiring the current value supplied to the motor, and an acceleration acquiring means for acquiring the rotational acceleration of the motor. , The current supplied to the motor is controlled so that the opening / closing operation of the sliding door is started according to the operation of the door handle, and then the operation duration measured by the measuring means is equal to or longer than a predetermined time and the current value. When at least one of the current value acquired by the acquisition means decreases below the current threshold value or the rotational acceleration acquired by the acceleration acquisition means increases above the acceleration threshold value, the opening / closing speed of the sliding door increases. It includes a control means for controlling the supplied current.

According to this configuration, when the user operates the door handle, the sliding door is opened and closed by the driving force of the motor. After that, if the user simply operates the door handle continuously for a long time, the operation may be an operation due to the user's habit or an operation intended to stop the opening / closing operation of the sliding door. The user does not necessarily intend to open and close the sliding door quickly. On the other hand, when the user applies a force in the moving direction of the sliding door to the door handle while continuously operating the door handle, it is considered that the user intends to quickly open and close the sliding door. When a force in the moving direction of the sliding door is applied to the door handle, the opening / closing operation of the sliding door is assisted by the force, so that the current value supplied to the motor decreases and the rotational acceleration of the motor increases.

Therefore, the operation of the door handle by the user continues for a predetermined time or longer, and at least one of the current value supplied to the motor decreases below the current threshold value and the rotational acceleration of the motor rises above the acceleration threshold value. If is satisfied, the current supplied to the motor is controlled and the opening / closing speed of the sliding door is increased. As a result, when the user intends to open and close the sliding door quickly, the opening / closing speed of the sliding door can be increased appropriately according to the intention, and the opening / closing speed of the sliding door increases unexpectedly by the user. It is possible to suppress giving the user a sense of discomfort due to this.

In the control means, the operation duration measured by the measuring means is longer than a predetermined time, the current value acquired by the current value acquiring means drops below the current threshold, and the rotational acceleration acquired by the acceleration acquiring means is The current supplied to the motor may be controlled so that the opening / closing speed of the sliding door increases when the acceleration threshold is exceeded.

With this configuration, when the user intends to open and close the sliding door quickly, the opening and closing speed of the sliding door can be increased more appropriately according to the intention.

According to the present invention, when the user intends to open and close the sliding door quickly, the opening / closing speed of the sliding door can be increased appropriately according to the intention, and the opening / closing speed of the sliding door unexpectedly increased by the user. It is possible to suppress giving the user a sense of discomfort due to the above, and it is possible to ensure the safety of the opening and closing operation of the sliding door.

In the following description, since it is not necessary to distinguish between the outdoor handle 7 and the indoor handle of the sliding door 5, these are collectively referred to as "door handle 7".

<Electric sliding door>
FIG. 2 is a block diagram showing an electrical configuration relating to control of opening / closing operation of the sliding door 5.

An electric sliding door (power sliding door) is adopted as the sliding door 5, and a door motor unit 11 for electrically opening and closing is provided. The door motor unit 11 includes, for example, a door motor 12, a door drive mechanism 13 that slides the slide door 5 in the front-rear direction by the power of the door motor 12, a door position sensor 14 for acquiring the position of the slide door 5, and a door motor. A motor current sensor 15 for acquiring the current supplied to the door motor 12 and a motor rotation sensor 16 for acquiring the rotation speed of the door motor 12 and the like are provided.

The vehicle 1 is equipped with an ECU (Electronic Control Unit) having a configuration including a microcomputer (microcontroller unit). The microcomputer has, for example, a CPU, a ROM, a RAM, a data flash (flash memory), and the like. FIG. 2 shows only an ECU (sliding door ECU) 21 for controlling the opening / closing operation of the sliding door 5, but the vehicle 1 is equipped with a plurality of ECUs for controlling each part. .. A plurality of ECUs including the sliding door ECU 21 are connected so as to enable bidirectional communication by a CAN (Controller Area Network) communication protocol.

Each detection signal of the door position sensor 14, the motor current sensor 15, and the motor rotation sensor 16 is input to the sliding door ECU 21.

The door position sensor 14 is provided, for example, in connection with a rotating body (roller or the like) that rotates with the movement of the sliding door 5, and outputs a pulse signal synchronized with the rotation of the rotating body as a detection signal. The sliding door ECU 21 acquires the position of the sliding door 5 based on the number of pulse signals input from the door position sensor 14.

The motor current sensor 15 outputs a detection signal according to the current supplied to the door motor 12. The sliding door ECU 21 acquires the current value flowing through the door motor 12 from the detection signal of the motor current sensor 15.

The motor rotation sensor 16 outputs a pulse signal synchronized with the rotation of the rotor of the door motor 12 as a detection signal. The sliding door ECU 21 acquires the rotation speed (rotation speed) of the door motor 12 by calculation from the detection signal of the motor rotation sensor 16, and further acquires the rotation acceleration of the door motor 12 by calculation from the rotation speed.

Further, on / off signals of the door handle switch 31, the door open / close switch 32, the one-touch switch 33, the keyless switch 34, and the like are input to the sliding door ECU 21. The door handle switch 31, the door open / close switch 32, the one-touch switch 33, and the keyless switch 34 are all momentary operation type switches.

The door handle switch 31 is held on while the user is performing an operation of pulling the door handle 7 (see FIG. 1) toward the front (hereinafter, simply referred to as “operation”), and the door handle switch 31 is held on while the operation is not performed. Keeps off.

The door open / close switch 32 is arranged at a position where the user can operate the door while sitting in the driver's seat. The door open / close switch 32 includes an open switch that is pushed to instruct the opening operation of the slide door 5 and a closing switch that is pushed to instruct the closing operation of the slide door 5.

The one-touch switch 33 is arranged near the door handle 7 or the door handle 7.

The keyless switch 34 is provided in a portable remote controller in a so-called key-free system (keyless entry system), which is a system that can lock (lock) / unlock (unlock) a door without inserting a key into a key cylinder. ..

For example, when the door handle 7 is operated or the door open / close switch 32 is opened, the one-touch switch 33 or the keyless switch 34 is pressed while the sliding door 5 is in the fully closed position, the sliding door 5 is operated. The ECU 21 controls the current supplied to the door motor 12 from the battery mounted on the vehicle 1 so that the sliding door 5 opens based on the current value flowing through the door motor 12 and the rotational acceleration of the door motor 12. .. Further, when the door handle 7 is operated or the door open / close switch 32 is closed, the one-touch switch 33 or the keyless switch 34 is pressed while the slide door 5 is in the fully open position, the slide door ECU 21 presses the door handle 7. The current supplied to the door motor 12 from the battery mounted on the vehicle 1 is controlled so that the sliding door 5 closes based on the current value flowing through the door motor 12 and the rotational acceleration of the door motor 12.

The control of the opening / closing operation of the sliding door 5 when the door handle 7 is operated will be described in detail below.

<Opening and closing operation control>
3A and 3B are flowcharts showing a flow of processing for controlling the opening / closing operation of the sliding door 5.

The process shown in FIGS. 3A and 3B by the slide door ECU 21 when the ignition switch of the vehicle 1 is on and the slide door 5 is stopped in the fully open state, the fully closed state, or the temporary holding state in the middle of opening and closing. Is executed.

In this process, first, it is determined whether or not the door handle switch 31 is turned on (step S1). The determination is repeated at regular intervals until the door handle switch 31 is turned on (NO in step S1).

When the door handle 7 is operated by the user and the door handle switch 31 is turned on (YES in step S1), the first timer is then activated (step S2). The first timer measures the elapsed time since the door handle switch 31 is turned on.

Further, when the door handle switch 31 is turned on, the opening / closing operation (PSD operation) of the sliding door 5 is started (step S3). That is, when the door handle switch 31 is turned on while the sliding door 5 is fully closed or temporarily held during the opening operation, the current supplied to the door motor 12 is controlled according to the turning on. The opening operation of the sliding door 5 is started. When the door handle switch 31 is turned on while the sliding door 5 is in the fully open state or in the temporary holding state during the closing operation, the current supplied to the door motor 12 is controlled according to the turning on, and the sliding door 5 is controlled. The closing operation of is started.

After that, it is determined whether or not the door handle switch 31 is switched from on to off (step S4).

When the operation of the door handle 7 is continued and the door handle switch 31 remains ON (NO in step S4), whether or not the measurement time by the first timer has exceeded the predetermined time, that is, whether the door handle 7 has been operated. It is determined whether or not the time during which the operation is continued (operation continuation time) is equal to or longer than the predetermined time (step S5).

While the measurement time by the first timer is less than the predetermined time (NO in step S5), it is repeatedly determined whether or not the door handle switch 31 is switched from on to off (step S4).

If the operation of the door handle 7 is released and the door handle switch 31 is switched from on to off before the measurement time by the first timer reaches the predetermined time (YES in step S4), the current PSD operation is continued. (Step S6).

During the opening operation of the slide door 5, it is determined whether or not the slide door 5 has reached the fully open position (step S7), and if the slide door 5 has not reached the fully open position (NO in step S7), the door handle switch. It is determined whether or not 31 is turned on again (step S8). If the door handle switch 31 remains off (NO in step S8), it is determined again whether or not the sliding door 5 has reached the fully open position (step S7). In this way, during the opening operation of the slide door 5, determination of whether or not the slide door 5 has reached the fully open position (step S7) and determination of whether or not the door handle switch 31 is turned on are alternately repeated. (Step S8).

During the closing operation of the slide door 5, it is determined whether or not the slide door 5 has reached the fully closed position (step S7), and if the slide door 5 has not reached the fully closed position (NO in step S7), the door It is determined whether or not the handle switch 31 is turned on again (step S8). If the door handle switch 31 remains off (NO in step S8), it is determined again whether or not the sliding door 5 has reached the fully closed position (step S7). In this way, during the opening operation of the slide door 5, determination of whether or not the slide door 5 has reached the fully closed position (step S7) and determination of whether or not the door handle switch 31 is turned on are alternately repeated. (Step S8).

When the door handle 7 is not operated, the door handle switch 31 is not turned on, and the sliding door 5 reaches the fully open position or the fully closed position (YES in step S7), the PSD operation is terminated (step S9). ), This process ends.

On the other hand, when the door handle 7 is operated while the sliding door 5 is stopped and the operation is continued for a predetermined time or longer (YES in step S5), the current threshold value and the acceleration threshold value are calculated (step S10 in FIG. 3B). ).

For the calculation of the current threshold, when the slide door 5 is located at a plurality of positions set at approximately equal intervals between the fully open position and the fully closed position during the PSD operation (opening / closing operation of the slide door 5), The current value supplied to the door motor 12 is acquired. Then, when the PSD operation is normally completed without the slide door 5 stopping halfway from the fully open / fully closed position to the fully closed / fully open position, each current value acquired during the PSD operation is recorded in the data flash. NS. In the data flash, a predetermined number of samplings are stored from the latest acquired current value at each position by a FIFO (First In First Out) method.

The current value recorded in the data flash may be the current value itself acquired from the detection signal of the motor current sensor 15, or the slide door ECU 21 may obtain the current value acquired from the detection signal of the motor current sensor 15. The current value may be corrected according to the vehicle inclination (inclination of the road surface on which the vehicle 1 is located) g'acquired from the ECU of the above. In the latter case, for example, the current value E obtained by the following equation (1) may be recorded in the data flash.

E = D + k * g'・ ・ ・ (1)
However, D: the current value acquired from the detection signal of the motor current sensor 15.
k: Correction coefficient

The vehicle inclination g'can be obtained from the detection signal of the G sensor mounted on the vehicle 1. That is, for example, the G sensor outputs a signal corresponding to the displacement of the weight as a detection signal corresponding to the acceleration of the vehicle 1, and the acceleration acquired from the detection signal of the G sensor depends on the change in the vehicle speed. The acceleration component and the acceleration component due to the vehicle inclination g'are included. On the other hand, the acceleration obtained by differentiating the vehicle speed is only the acceleration component due to the change in the vehicle speed. Therefore, by obtaining the difference between the acceleration acquired from the detection signal of the G sensor and the differential value of the vehicle speed, the acceleration component due to the vehicle inclination g'can be obtained, and the vehicle inclination g'can be calculated from the acceleration component. can.

The current threshold value is calculated in each of a plurality of sections obtained by dividing the slide door 5 between the fully open position and the fully closed position into a plurality of sections. For the calculation, the average value Eave and the standard deviation σE of the current values in each section are calculated using the current values stored in the data flash. Then, when the slide door 5 is opened, the current threshold value Sa for each section is calculated according to the following equation (2). When the sliding door 5 is closed, the current threshold value Sa for each section is calculated according to the following equation (3).

Sa = Eave-k * g'-4 * σE ... (2)

Sa = Eave-k * g'+ 4 * σE ... (3)

The acceleration threshold value is calculated by adding a predetermined tolerance width to the acceleration target value set from the rotation speed target value of the door motor 12 at each position of the slide door 5.

When the current threshold value and the acceleration threshold value are calculated, the third timer is activated (step S11). The second timer measures the elapsed time after the calculation of the current threshold value and the acceleration threshold value.

Further, after calculating the current threshold value and the acceleration threshold value, the current current value is acquired from the detection signal of the motor current sensor 15, and whether or not the current value is less than the current threshold value in the section including the current position of the slide door 5. Is determined (step S12).

When the current value is less than the current threshold value (YES in step S12), the rotation or speed of the door motor 12 is acquired, and it is determined whether or not the rotational acceleration is equal to or more than the acceleration threshold value (step S13).

If rotational acceleration of the door motor 12 is less than the acceleration threshold (NO in step S13), and current PSD operation is continued (Fig. 3 A step S6 in).

When the rotational acceleration of the door motor 12 is equal to or greater than the acceleration threshold value (YES in step S13), it is determined whether or not the position of the slide door 5 is the assist reception position (step S14). When the position of the slide door 5 is within a predetermined section between the fully open position and the fully closed position, the position of the slide door 5 is determined to be the assist reception position, and the position of the slide door 5 is outside the predetermined section. , It is determined that the position of the slide door 5 is not the assist reception position.

If the position of the sliding door 5 is not the assist reception position (NO in step S14), and current PSD operation is continued (Fig. 3 A step S6 in).

When the position of the slide door 5 is the assist reception position (YES in step S14), the current supplied to the door motor 12 is controlled so that the opening / closing speed of the slide door 5 increases from the current speed (step S15). .. As a result, the sliding door 5 opens and closes (assists) at a higher speed than during normal PSD operation.

During the assist operation, it is monitored whether or not the door handle switch 31 is switched from on to off (step S16).

The assist operation is continued until the operation of the door handle 7 is released and the door handle switch 31 is switched from on to off. Then, when the operation of the door handle 7 is released and the door handle switch 31 is switched from on to off (step S16: YES), the current supplied to the door motor 12 is reduced so that the opening / closing speed of the sliding door 5 is reduced. It is controlled and returned to normal PSD operation (step S6 in FIG. 6A).

On the other hand, during normal PSD operation, the operation of the door handle 7 is made again after being released once, when the door handle switch 31 is turned on (YES in Fig. 3 A step S8 in), the second timer start (Step S17). The second timer measures the elapsed time since the door handle switch 31 is turned on.

After that, it is determined whether or not the door handle switch 31 is switched from on to off (step S18).

When the operation of the door handle 7 is continued and the door handle switch 31 remains ON (NO in step S18), whether or not the measurement time by the second timer exceeds the predetermined time, that is, whether the door handle 7 is operated. It is determined whether or not the time during which the operation is continued (operation continuation time) is equal to or longer than the predetermined time (step S19).

While the measurement time by the second timer is less than the predetermined time (NO in step S19), it is repeatedly determined whether or not the door handle switch 31 is switched from on to off (step S18).

When the door handle 7 is operated during the PSD operation of the sliding door 5 and the operation is continued for a predetermined time or longer (YES in step S18), the current threshold value and the acceleration threshold value are calculated (step S10), as described above. The processing after step S11 proceeds.

On the other hand, after the door handle 7 is operated during the PSD operation of the sliding door 5, the operation of the door handle 7 is released and the door handle switch 31 is turned on before the measurement time by the second timer reaches a predetermined time. When the door is switched off (YES in step S18), it is determined whether or not the position of the slide door 5 is the temporary holding reception position (step S20). When the position of the slide door 5 is on the fully open position side of the predetermined position, it is determined that the position of the slide door 5 is the temporary holding reception position, and the position of the slide door 5 is on the fully closed position side of the predetermined position. In the case of the position, it is determined that the position of the slide door 5 is not the temporary holding reception position.

When the position of the slide door 5 is the temporary holding reception position (YES in step S20), the PSD operation is stopped by controlling the current supplied to the door motor 12, and the position of the slide door 5 is held at the stopped position. (Step S21). As a result, when the user operates the door handle 7 for a short time during the PSD operation, it is considered that the user intends to stop the sliding door 5. In this case, the sliding door 5 can be stopped as appropriate for the user's intention. After the slide door 5 is stopped, the process returns to the beginning of this process, and it is determined whether or not the door handle switch 31 is turned on (step S1).

If the position of the slide door 5 is not the temporary holding reception position (NO in step S20), if the slide door 5 is in the open operation, the PSD operation is continued, and if the slide door 5 is in the closed operation. The current supplied to the door motor 12 is controlled so that the operating direction of the sliding door 5 is reversed, that is, the sliding door 5 is opened (step S22: reverse opening operation). After that, the process returns to the beginning of this process, and it is determined whether or not the door handle switch 31 is turned on (step S1).

Further, after the operation of the door handle 7 is continued for a predetermined time or more measured by the first timer or the second timer and the current threshold value and the acceleration threshold value are calculated (step S10), the current value is equal to or higher than the current threshold value. In the case (NO in step S12), whether or not the measurement time by the third timer is equal to or longer than the predetermined time, that is, the operation of the door handle 7 whose current value becomes equal to or longer than the current threshold after the calculation of the current threshold and the acceleration threshold is longer than the predetermined time. Whether or not it continues is determined (step S23).

While the measurement time by the third timer is less than the predetermined time (NO in step S23), it is determined whether or not the door handle switch 31 is switched from on to off (step S24).

When the operation of the door handle 7 is continued and the door handle switch 31 remains ON (NO in step S24), it is determined again whether or not the current value is less than the current threshold value (step S12).

Then, when the operation of the door handle 7 whose current value is equal to or greater than the current threshold value continues for a predetermined time or longer and the measurement time by the third timer exceeds the predetermined time (YES in step S23), the user opens and closes the slide door 5. It is considered that it is not trying to operate it, but trying to stop its opening / closing operation. Therefore, in such a case, it is determined whether or not the position of the slide door 5 is the temporary holding reception position (step S20).

When the position of the slide door 5 is the temporary holding reception position (YES in step S20), the PSD operation is stopped by controlling the current supplied to the door motor 12, and the position of the slide door 5 is held at the stopped position. (Step S21). As a result, the sliding door 5 can be stopped as intended by the user.

On the other hand, when the position of the slide door 5 is not the temporary holding reception position (NO in step S20), as described above, if the slide door 5 is in the open operation, the slide door 5 is operated so that the PSD operation is continued. During the closing operation, the current supplied to the door motor 12 is controlled so that the operating direction of the sliding door 5 is reversed, that is, the sliding door 5 is opened (step S221: reverse opening operation). After that, the process returns to the beginning of this process, and it is determined whether or not the door handle switch 31 is turned on (step S1).

<Effect>
As described above, when the user operates the door handle 7, the opening / closing operation (PSD operation) of the sliding door 5 by the driving force of the door motor 12 starts. After that, if the user simply operates the door handle 7 continuously for a long time, the operation may be an operation due to the user's habit or an operation intended to stop the opening / closing operation of the slide door 5. , The user does not necessarily intend to open and close the sliding door 5 quickly. On the other hand, when the user applies a force in the moving direction of the sliding door 5 to the door handle 7 while continuously operating the door handle 7, it is considered that the user intends to quickly open and close the sliding door 5. .. When a force in the moving direction of the slide door 5 is applied to the door handle 7, the opening / closing operation of the slide door 5 is assisted by the force, so that the current value supplied to the door motor 12 decreases and the rotational acceleration of the door motor 12 increases. To rise.

Therefore, when the operation of the door handle 7 by the user continues for a predetermined time or longer, the current value supplied to the door motor 12 drops below the current threshold value, and the rotational acceleration of the door motor 12 rises above the acceleration threshold value. The current supplied to the door motor 12 is controlled to increase the opening / closing speed of the sliding door 5. As a result, when the user intends to open and close the slide door 5 quickly, the opening and closing speed of the slide door 5 can be increased appropriately according to the intention, and the user unexpectedly opens and closes the slide door 5. It is possible to suppress giving the user a sense of discomfort due to the increase in the speed.

<Modification example>
Although one embodiment of the present invention has been described above, the present invention can also be implemented in other embodiments.

For example, in the above-described embodiment, the operation of the door handle 7 by the user continues for a predetermined time or longer, the current value supplied to the door motor 12 is reduced to less than the current threshold value, and the rotational acceleration of the door motor 12 is the acceleration threshold value. When it rises above the above, the opening / closing speed of the sliding door 5 is said to be increased. However, when the operation of the door handle 7 by the user continues for a predetermined time or longer and the current value supplied to the door motor 12 drops below the current threshold value, or the rotational acceleration of the door motor 12 rises above the acceleration threshold value. In addition, the opening / closing speed of the sliding door 5 may be increased.

Further, in the above-described embodiment, the sliding door ECU 21 is configured as one ECU by itself, but the function of the sliding door ECU 21 and the function of another ECU may be incorporated into one ECU.

In addition, various design changes can be made to the above-mentioned configuration within the scope of the matters described in the claims.
