Description

The present invention relates to a vehicle door closer device that controls the movement of a vehicle door from a half-door position to a fully closed position.

Conventionally, in a vehicle such as an automobile, a vehicle door closer device has been proposed in which an actuator is controlled by a control means mounted on the vehicle to move a door from a substantially closed half-door position to a fully closed position (Patent Document). 1). In such a door closer device, a predetermined door position is stored in advance by the door position storage unit, the door position when the door is fully closed is acquired by the door position acquisition unit, and the door is closed by the closer. After the start, when the door position acquired from the door position acquisition unit reaches the predetermined door position stored in the door position storage unit, the closer control unit temporarily stops the door closing operation by the closer to determine the predetermined door position. After a lapse of time, the door closing operation by the closer is restarted to fully close the door.

Japanese Unexamined Patent Publication No. 2009-197483 (see paragraphs 0022 to 0025 and FIG. 1 etc.)

However, in the configuration described in Patent Document 1, since the predetermined door position for temporarily stopping the door closing operation is not detected by a sensor or the like, the door closing speed and closing time are caused by, for example, variations in the battery voltage. As a result, the timing of determining whether or not the door is in the predetermined position varies, and the time to reach the door stop position in the middle or the door stop position in the middle varies, and the occupant's finger pinch. In some cases, it may be delayed to notice the finger pinch. In addition, when the door closing operation is temporarily stopped and the door closing operation by the closer is restarted after a predetermined time has elapsed, the time until the door closing operation is temporarily stopped becomes longer and the door is fully closed. It takes too long and the occupants feel frustrated.

On the other hand, it is conceivable to provide a detection switch for detecting the door stop position to prevent variations in the door stop position, but the provision of the detection switch raises a new problem that the device configuration becomes complicated and expensive.

The present invention has been made in view of the above problems, and an object of the present invention is to allow an occupant to have a margin to notice a finger pinch. It also aims to prevent the occupants from feeling frustrated because the doors are fully closed for too long.

In order to achieve the above object, the door closer device of the vehicle of the present invention controls an actuator by a control means mounted on the vehicle to move the door from a substantially closed half-door position to a fully closed position. In the door closer device of the above, the position of the door is determined according to the voltage detecting means for detecting the power supply voltage of the control means by the battery mounted on the vehicle and the high or low of the power supply voltage detected by the voltage detecting means. It is characterized by comprising a switching means for switching between a short time and a long time from the half-door position to an intermediate position set in the middle between the half-door position and the fully closed position.

According to such a configuration, when the power supply voltage of the control means by the battery is high, the time from the half-door position to the middle position of the door is shortened, and when the power supply voltage of the control means by the battery is low, the door is half. Since the time from the door position to the halfway position becomes long, by changing the time until the door reaches the halfway position, the timing at which the door stops halfway is changed and the halfway position itself varies. This can be prevented and provide sufficient room for the occupant to notice the finger pinch.

Further, the control means controls to move the door from the half-door position to the fully closed position in a predetermined time, after stopping the door in the middle position, and then moving the door to the fully closed position. Even if the switching means switches the time for stopping the door to the intermediate position between long and short according to the high and low of the power supply voltage detected by the voltage detecting means. good.

According to such a configuration, when the power supply voltage of the control means by the battery is high, the stop time at the middle position of the door is long, and when the power supply voltage of the control means by the battery is low, the stop time at the middle position of the door is short. Therefore, it is possible to change the time that the door is stopped in the middle position while keeping the time from the half-door position to the fully closed state constant regardless of the power supply voltage of the control means by the battery. Therefore, it is possible to prevent the occupant from feeling frustrated because the fully closed time is too long as in the conventional case.

According to the present invention, the time from the half-door position to the middle position of the door is switched between short and long depending on the high and low power supply voltage of the control means by the battery. Therefore, when the power supply voltage of the control means is high. By shortening the time it takes for the door to reach the midway position and increasing the time it takes for the door to reach the midway position when the power supply voltage of the control means is low, the timing at which the door stops halfway can be changed. It is possible to prevent the position itself from fluctuating, and it is possible to give a margin for the occupant to notice the finger pinch, and it is possible to improve the safety.

It is a schematic diagram of the vehicle equipped with the door closer device which concerns on one Embodiment of this invention. It is a block diagram of a door closer device. It is an operation explanatory diagram of FIG. It is an operation explanatory diagram of FIG.

An embodiment of a vehicle door closer device according to the present invention will be described with reference to FIGS. 1 to 4. The front / rear and left / right in the present embodiment mean the front / rear and left / right when viewed while sitting on the seat.

As shown in FIG. 1, the door closer device is provided on the left and right hinge doors 2 on the front seat side of the vehicle (automobile) 1, and is a closer motor which is an actuator by a closer ECU (Electronic Control Unit) 3 having a microcomputer configuration as a control means. 4 is controlled, the door 2 is moved from the half-door position to the fully closed state by the closer motor 4, and the upper lock striker 5a and the lower lock striker 5b of the door 2 are operated to lock the door 2 to the fully closed state.

At this time, as shown in FIG. 2, a power supply voltage is supplied to the closer ECU 3 by a battery (not shown) mounted on the vehicle 1. The closer ECU 3 is separated from CAN (Controller Area Network) communication performed between a plurality of other ECUs mounted on the vehicle 1.

By the way, the power supply voltage of the battery 6 to the closer ECU 3 is detected by the closer ECU 3 itself, and the door 2 is fully closed from the half-door position to the half-door position by the closer ECU 3 according to the high and low of the detected power supply voltage. The time to reach the intermediate position set in the middle of the position is switched between short and long. Further, the time required to move the door 2 from the half-door position to the fully closed position is set to a predetermined fixed time, and the door is operated by the closer ECU 3 according to the high or low power supply voltage. The time for stopping 2 in the middle position can be switched between long and short. Such a switching function by the closer ECU 3 corresponds to the switching means in the present invention.

Subsequently, the operation of the door 2 from the half-door position to the fully closed position under the control of the closer ECU 3 will be described with reference to FIGS. 3 and 4.

As shown in FIG. 3, there are three door positions, a "half-door position", a "fully closed position", and a "halfway position" set between the half-door position and the fully closed position, which are controlled by the closer ECU 3. The closer motor 4 is driven and controlled, and the time T from the half-door position to the fully closed position of the door 2 is kept constant, while the time Ta from the half-door position to the halfway position of the door 2 Ta, and The time Tb at which the door 2 is stopped in the middle position of the door 2 is variable depending on whether the power supply voltage of the closer ECU 3 by the battery 6 is high or low. When the stop time Tb at the halfway position has elapsed, the closer motor 4 takes time Tc (= T-Ta-Tb) until the door 2 moves from the halfway position to the fully closed position, and the door 2 is in the fully closed state. Is controlled by.

Then, for example, when the switch for activating the closer of the portable remote controller held by the occupant is operated, the power supply voltage of the closer ECU 3 by the battery 6 is detected by the closer ECU 3, and the detected power supply voltage is set from a predetermined value. When it is high, as shown in FIG. 3, the time from the half-door position to the middle position of the door 2 is set to the initial value time Ta, and the stop time at the middle position of the door 2 is the initial value. The door 2 is set to Tb for a certain period of time, and then the door 2 is fully closed over a period of time Tc (= T-Ta1-Tb1) until the door 2 is fully closed.

On the other hand, when the power supply voltage detected by the closer ECU 3 is lower than the predetermined value Vt when the switch for activating the closer of the mobile remote controller is operated, the door 2 is moved from the half-door position to the middle position as shown in FIG. The time to reach is switched to Tal (> Ta) longer than the initial value Ta, and the stop time at the middle position of the door 2 is shorter than the initial time Tb Tbl (<Tb). After that, the door 2 is fully closed over time Tc (= T-Tal-Tbl) until the door 2 is fully closed. At this time, as the stop time Tbl at the middle position of the door 2, a sufficient length (for example, 1 second) is secured so that the occupant notices the finger pinch and pulls out the finger from the gap between the door 2 and the body. It is preferable to set it to. The values of these time Ta (initial value), Tb (initial value), Ta1, Tb1 and voltage Vt may be experimentally obtained in advance and stored in the built-in memory of the closer ECU 3.

It should be noted that a time different from each of the above-mentioned times Ta and Tb is stored in the built-in memory of the closer ECU 3 as an initial value, and when the detected power supply voltage of the closer ECU 3 is higher than a predetermined predetermined value Vt, the door 2 is stored. Sets the time from the half-door position to the halfway position to Tah for a shorter time than the initial value, and switches the stop time at the middle position of the door 2 to Tbh for a longer time than the initial value, and the detected closer. When the power supply voltage of the ECU 3 is lower than the predetermined value Vt, the time from the half-door position to the halfway position of the door 2 is switched to Tal (> Tah) for a longer time than the initial value, and the door 2 is set. The stop time at the midway position may be switched to Tbl (<Tbh) for a time shorter than the initial value and set.

Therefore, according to the above-described embodiment, when the power supply voltage of the closer ECU 3 by the battery 6 is high, the time from the half-door position to the halfway position of the door 2 is short, and when the power supply voltage is low, the door 2 is a half-door. Since the time from the position to the halfway position becomes long, by changing the time until the door 2 reaches the halfway position, the timing at which the door 2 stops halfway is changed, and the halfway position itself varies. Can be prevented and sufficient room for the occupant to notice the finger pinch.

Further, when the power supply voltage of the closer ECU 3 by the battery 6 is high, the stop time at the middle position of the door 2 is long, and when the power supply voltage is low, the stop time at the middle position of the door 2 is short, so that the door 2 is in the half-door position. The time T from to the fully closed state to the fully closed state can be kept constant regardless of the power supply voltage of the closer ECU 3, and the time when the door 2 is stopped in the middle position can be changed, as in the conventional case. It is possible to prevent the occupants from feeling frustrated because the fully closed time is too long.

Further, based on the high and low power supply voltage of the closer ECU 3 by the battery 6, the time from the half-door position of the door 2 to the middle position is switched between short and long, and the stop time at the middle position of the door 2 is long. Although it is switched to short, even if the closer ECU 3 is disconnected from the CAN communication as described above and the information on the terminal voltage of the battery 6 cannot be directly acquired, the terminal voltage of the battery 6 is changed from the power supply voltage of the closer ECU 3 by the battery 6. It becomes possible to control the door closer device according to the terminal voltage of the battery 6.

The present invention is not limited to the above-described embodiment, and various modifications can be made other than those described above as long as the present invention is not deviated from the gist thereof.

For example, in the above-described embodiment, the time from the half-door position of the door 2 to the fully closed state is kept constant, and when the power supply voltage of the closer ECU 3 by the battery 6 is high, the stop time in the middle position is lengthened. The time from the half-door position to the halfway position of the door 2 is shortened, the stop time at the halfway position is shortened when the power supply voltage is low, and the time from the half-door position to the halfway position of the door 2 is lengthened. Although the case has been described, at least the time from the half-door position to the middle position is set to be short or long according to the high and low power supply voltage of the closer ECU 3, and the door 2 is set from the half-door position to the middle position. The time to time may be constant. In this case, the time from the half-door position of the door 2 to the fully closed state becomes longer or shorter depending on the high or low power supply voltage of the closer ECU 3, but the time until the door 2 reaches the middle position is set. By making it variable, it is possible to change the timing at which the door 2 stops in the middle and prevent the midway position itself from being varied.

Further, in the above-described embodiment, the case where the present invention is applied to the hinge door 2 has been described, but it goes without saying that the present invention can also be applied to the sliding door.

Further, the present invention can be applied to a door closer device that controls an actuator by a control means mounted on a vehicle to move a door from a substantially closed half-door position to a fully closed position.
