  In the devices of Patent Literature 1 and Patent Literature 3, when there is an object such as a vehicle that approaches the host vehicle from behind, a sound alarm is provided as one of means for preventing contact between the approaching object and the vehicle door. Is issued to alert the passenger. Therefore, there is a possibility that effective alerting cannot be performed when the passenger has a hearing impairment or in a noisy environment. Moreover, there is a possibility that it is impossible to understand what the alarm is based on the alarm based on the sound described above or the alarm based on the vibration of the vehicle seat described in Patent Document 3. Even if it is understood that there is a possibility of contact with a vehicle traveling behind when the door is opened, the door opening operation is stopped after the passenger recognizes the alarm and understands the alarm target. For this reason, it is considered that the passenger cannot be alerted intuitively, and there is room for further improvement in this regard.

  In the devices described in Patent Documents 1 to 3, a door lock has been proposed as another means for preventing contact between an object approaching the host vehicle from behind and a vehicle door. However, if the door is locked, there is a problem that the door cannot be opened even if the device malfunctions or the passenger wants to open the door anyway.

  The present invention has been made in view of the above circumstances, and when a contact with an object such as a vehicle approaching from behind is expected when the door is opened, appropriate warning is given to the passenger. It is an object of the present invention to provide a vehicle door open / close warning device capable of performing the above.

  In order to achieve the above object, the present invention provides an open / close warning device for a vehicle door that issues an alarm for an operation when the vehicle door is opened from the inside of the vehicle. A door opening sensor for detecting the opening operation of the inside handle, a rear vehicle sensor for detecting an object approaching the host vehicle from the rear, and a vibration alarm for vibrating the inside handle. When the object that contacts the vehicle from behind is detected, and the door opening sensor detects the opening operation of the inside handle by a passenger, the vibration alarm is activated to vibrate the inside handle and the boarding It is configured to issue a warning to a person.

  According to the present invention, the inside handle vibrates when there is a possibility of contact between the door of the host vehicle and a vehicle approaching from behind, so the passenger recognizes that there is some inconvenience in opening the door, The door opening operation can be canceled intuitively. As a result, contact between the door of the host vehicle and a vehicle approaching from behind can be prevented. Further, since the door is not forcibly locked, the door can be opened at the will of the passenger even when the door needs to be opened.

It is a block diagram for demonstrating the control logic performed with the vehicle door opening / closing warning apparatus which concerns on this invention. It is a figure which shows the inside handle to which the opening / closing warning device of the vehicle door which concerns on this invention is attached.

  An embodiment of the present invention will be described with reference to the drawings. As shown in a block diagram in FIG. 1, the vehicle door opening / closing warning device according to the present invention includes a rear vehicle sensor 1, an opening sensor 2, and a vibration alarm device 3.

  The rear vehicle sensor 1 is a sensor for detecting an object such as a vehicle approaching the host vehicle from behind, and specifically, a laser radar or a millimeter wave radar like a conventionally known blind spot monitor. Means for detecting an object such as a vehicle entering the rear warning area is used. A sensor that detects an object using image processing can also be used.

  The door opening sensor 2 detects a door opening operation of the door 5 by a passenger, and specifically, a conventionally known touch sensor that detects that the passenger touches the inside handle 4. Can be adopted. In addition to a sensor that emits a signal when the capacitance changes, a conventionally known sensor that emits a signal when a passenger approaches the vehicle may be used.

  The vibration alarm device 3 is used to warn the door opening operation, and specifically, a mechanism that generates vibration such as a small motor can be employed.

  An inside handle 4 that is a handle for opening and closing the door 5 of the vehicle is a handle for opening the door 5 from the passenger compartment. FIG. 2 shows the inside handle 4 provided in the driver's seat as an example. Yes. The inside handle 4 is provided inside the door 5 and is provided with the door opening sensor 2 and the vibration alarm device 3 described above.

  Next, the control logic executed in the present invention will be described with reference to the block diagram of FIG. When the rear vehicle sensor 1 detects the presence of a vehicle that may come into contact with the host vehicle from behind when the door 5 is opened, a signal is output to the vibration alarm device 3. Similarly, a signal is output to the vibration alarm device 3 when the door opening sensor 2 detects that the passenger has touched the inside handle 4. When the vibration alarm 3 receives these two signals, the vibration alarm 3 operates and the inside handle 4 vibrates. As a result, an intuitive warning for stopping the door opening operation of the door 5 can be given to the passenger at the moment when the passenger touches the inside handle 4. Therefore, it is possible to prevent contact between the door 5 of the host vehicle and a vehicle approaching the host vehicle from the rear.

  When the passenger senses the behavior change of the inside handle 4, the passenger can intuitively recognize that the behavior warning warns of a danger related to the door opening operation which is the immediately preceding operation. Further, when the passenger senses the vibration of the inside handle 4, the passenger tries to release his / her hand from the inside handle 4 which is the vibration source, so that the opening operation can be stopped naturally immediately before the opening operation. . Therefore, the alarm based on the vibration of the inside handle 4 adopted in the present invention is extremely effective in alerting as compared with the alarm based on the sound and the alarm based on the vibration of the seat, which are difficult to instantly grasp what is the target of the alarm. It can be carried out.

  In addition, since the door is not forcibly locked in the present invention, when the door needs to be opened regardless of the warning, such as when the door is opened and then closed again in order to remove an object caught in the door. The door can be opened at the will of the passenger.

  The vehicle door open / close warning device according to the present invention may be set for the door on the auxiliary seat, the door on the rear seat, and the like in addition to the door on the driver's seat. Further, in the present invention, it is only necessary to give the inside handle a behavior different from normal, and in addition to the vibration described above, the door opening stroke or the door operating force is increased in addition to the above-mentioned vibration. Including things like doing. Furthermore, in the present invention, in addition to the change in the behavior of the inside handle as described above, alerting by sound or illumination may be used in combination.
