Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to an automatic door operating device for an automobile, in which an appropriate drive source is operated by an operation switch to move a door.

[0002]

[Prior art]

 A conventional example of this type of apparatus is disclosed in, for example, Japanese Patent Laid-Open No. 57-191123. This device is equipped with a door moving device that opens and closes the door with an open / close switch, and also with a sensor that detects the presence of obstacles around the vehicle, so that an obstacle is detected while the door is being moved by the open / close switch. Then, the control circuit is turned off and the door moving device is stopped.

[0003]

[Problems to be solved by the device]

 However, even if the distance between the door and the obstacle is small enough to get on and off the door, the conventional device described above can operate the door until the door comes into contact with the obstacle by operating the open / close switch. Since the door is moved without opening, there is a risk that the opening of the door will be narrow and you will not be able to get in or out of the passenger compartment even though the door was opened. When such a situation occurs, there is a problem in that the door must be closed and the automobile must be moved, and then the open / close switch must be operated again to reopen the door.

In view of the above problems of the prior art, the present invention prevents a situation in which the door opening is narrow and the passenger cannot get in and out even though the door is opened by operating the operation switch. In addition, it is an object of the present invention to provide an automatic door operating device for an automobile, which improves the operation of opening the door.

[0005]

[Means for Solving the Problems]

 In order to achieve the above-mentioned object, the device of the present invention operates an appropriate drive source provided on either the vehicle body side or the door side by operating an operation switch to move the door. In the automatic door operation device of the automobile, the distance sensor detects the distance between the door and the obstacle and the distance detected by the distance sensor is compared with the preset door opening / closing angle, and the distance sensor detects the distance. Only when it is determined that the detected distance is larger than the door opening angle that allows the passenger to get in and out of the vehicle, there is provided a control unit that enables the operation of the operation switch to operate the drive source. It features a door operation device.

[0006]

[Action]

 The control unit compares and determines the preset door opening / closing angle with the distance between the door and the obstacle detected by the distance sensor, and if the distance between the door and the obstacle is larger than the door opening / closing angle. Only when the judgment is made, it is possible to open the door by validating the opening operation of the operation switch, assuming that the opening amount sufficient for getting on and off the door can be obtained.
