Description

  The present invention relates to a vehicle door opening position control device and a technology related thereto.

  As a method of limiting the opening degree of a vehicle door, for example, the distance to an obstacle existing in the direction in which the door opens is measured by an existing sonar sensor installed at four corners of the vehicle, and this measurement is performed. Based on the distance to the obstacle, the opening distance may be limited so that the door does not contact the obstacle. Thereby, it is possible to prevent the door from coming into contact with the obstacle. As a technique for preventing such a door from contacting an obstacle, for example, Patent Document 1 is disclosed.

JP 2004-034796 A

  In the above proposed example, the distance to the obstacle that exists in the direction in which the door opens is measured by a sonar sensor already mounted on the vehicle. In this case, the sonar sensor is installed in the vehicle in advance. It is a premise.

  For this reason, in the case of a vehicle in which a sonar sensor is not installed, the distance to an obstacle existing in the direction in which the door opens must be measured by a dedicated sensor. Therefore, there is a disadvantage that the cost of the dedicated sensor and the cost of installing this sensor increase.

  In the above proposal example, the door opening distance is limited only in accordance with the distance to the obstacle measured by the sonar sensor, but in reality, for example, the place where the vehicle is stopped or the occupant The appropriate opening position of the door also varies depending on other parameters such as the type of child (eg, children / adults), so it is desirable to adjust the opening position of the door to reflect these other parameters. There is a request.

  Therefore, an object of the present invention is to limit the opening degree of a door without using a sensor, and to adjust the opening position of the door by reflecting parameters other than the distance to the obstacle. It is to provide a position control device.

  In order to solve the above-mentioned problem, the invention according to claim 1 is configured such that a door opening degree control unit that restricts the opening degree of a vehicle door and a setting input by a user so that the opening degree of the door is associated with a predetermined setting condition. A door opening control condition input means, a display means for confirming and displaying the set condition, and determining whether or not a vehicle condition matches the set condition, and based on the determination result, And a processing means for controlling the door opening degree control unit.

  The invention according to claim 2 is the vehicle door opening position control device according to claim 1, further comprising occupant type detection means for detecting the occupant type, wherein the setting condition is at least the occupant type. And when the detection result of the occupant type detection means matches the occupant type as the setting condition, the processing means determines the nearest door opening of the occupant according to the occupant type. It is something to control.

  The invention according to claim 3 is the vehicle door opening position control device according to claim 1 or 2, wherein the setting condition includes at least the own vehicle position, and the processing means determines the own vehicle position. When the detection result of the vehicle position detection unit for detection matches the vehicle position as the setting condition, the door opening degree is controlled according to the vehicle position.

  A fourth aspect of the invention is the vehicle door opening position control device according to any one of the first to third aspects, further comprising display means for confirming and displaying the set condition. .

  In the vehicle door opening position control device according to the first aspect of the present invention, in the processing means, it is determined whether or not the condition of the vehicle matches the setting condition input in advance by the door opening control condition input means, Since the door opening control unit is controlled based on the determination result, the door opening control can be easily performed without using any sonar sensor or the like. Therefore, the cost of the sonar sensor and the cost for attaching the sonar sensor can be reduced.

  Since the vehicle door open position control device according to the fourth aspect of the present invention further includes display means for confirming and displaying the set condition, the user can easily perform the setting input operation using the door opening control condition input means. .

  As setting conditions, it is convenient to apply the occupant type as in claim 2 or apply the vehicle position as in claim 3.

<Configuration>
1 and 2 are block diagrams showing a vehicle door opening position control apparatus according to an embodiment of the present invention. This vehicle door opening position control device allows a user to set and input the opening degree of each door of the automobile to correspond to a predetermined setting condition, and when the situation of the automobile matches the above setting condition, The opening degree for each door is limited.

  Specifically, as shown in FIGS. 1 and 2, the vehicle door opening position control device includes a door opening control condition input means for a user to set and input the opening for each door so as to correspond to a predetermined setting condition. 1, a display unit (display means) 3 for confirming and displaying the above set conditions, a display control unit 5 for controlling the video display of the display unit 3, and a door opening degree control provided for each door .., And various situation information of the vehicle are collected to determine whether or not the above set conditions are met, and the door opening control units 7a, 7b... Are controlled based on the determination result. And a processing device (processing means) 9.

  Any door opening control condition input means 1 may be used as long as it performs some input operation such as a touch sensor, a joystick, a function switch, or a voice input device when the display unit 3 is a touch panel display. It can be applied. Setting conditions input by the door opening control condition input means 1 will be described later.

  As the display unit 3, for example, a dot matrix type liquid crystal display (LCD) is used. For example, when a touch panel display is applied as the display unit 3, as described above, a touch sensor can be applied as the door opening control condition input unit 1.

  Based on the control from the processing device 9, the display control unit 5 performs control related to the video display of the display unit 3 so as to confirm and display the setting condition input by the door opening control condition input unit 1. .

  The door opening control units 7a, 7b,... Are provided one-to-one with respect to each door of the automobile, and an actuator or the like for limiting the opening of the door is applied.

  The processing device 9 is an electronic control unit (ECU) having a CPU to which a nonvolatile memory and a RAM are connected, and is a functional element that operates in accordance with a software program stored in the nonvolatile memory in advance. The processing device 9 has a setting condition storage function for storing the setting condition input by the door opening control condition input means 1 in a nonvolatile memory and a predetermined in-vehicle communication network such as the in-vehicle LAN 11 (FIG. 2). Vehicle information collection function for collecting various situation information, condition judgment function for comparing and judging the collected automobile situation information and setting conditions in the nonvolatile memory, and automobile situation information and settings in the nonvolatile memory Has an opening setting function for setting the door opening control units 7a, 7b... Of each door when the conditions are met.

  Here, the vehicle status information collected by the processing device 9 includes, for example, the attached / detached state of the child seat, the occupant type, the position information of the host vehicle, and the vehicle speed.

  The state of attaching / detaching the child seat means whether or not the child seat is attached, and a child seat fixing mechanism that is installed in advance in the automobile, for example, a child seat attached to a child seat fixing dedicated anchor corresponding to ISO-FIX. It is detected by the attachment / detachment state detector 13 (attachment sensor). Further, whether or not a child is seated in the child seat is determined based on, for example, a signal from a passenger seat sensor (not shown) incorporated in the seat of the automobile on which the child seat is installed. As this passenger seat sensor, for example, a weight sensor or a body temperature sensor is applied. The child seat attachment / detachment state detection unit 13 is an element that functions as one of occupant type detection means for detecting the occupant type.

  The occupant type is detected by, for example, the occupant type detection unit 15 using a weight sensor or the like installed in each seat. The occupant type detection unit 15 is an element that functions as one of the occupant type detection means for detecting the occupant type together with the above-described child seat attachment / detachment state detection unit 13.

  For example, a car navigation system is applied as the vehicle position detection unit 17 for the position information of the vehicle, and the vehicle position detection function of the car navigation system and the vehicle position reception function from GPS are used. Alternatively, a predetermined operation input means such as a joystick attached to the car navigation system is used as the vehicle position detection unit 17, and the position of the car navigation system on the map is designated by the operation input means. There is no problem.

  The vehicle speed is detected by an existing electric vehicle speed detector (vehicle speed sensor) 19 disposed in the transmission or the like.

  The child seat attachment / detachment state detection unit 13, the occupant type detection unit 15, the vehicle position detection unit 17, and the vehicle speed detection unit 19 are connected to the in-vehicle LAN 11 via individual or common electronic control units (ECUs) 21a, 21b, and 21c, respectively. Each detection result is transmitted to the processing device 9 through a predetermined in-vehicle communication network such as (FIG. 2).

  And as the opening degree setting function of the processing device 9, for example, based on the detection results of the child seat attachment / detachment state detection unit 13 and the occupant type detection unit 15, the occupant type of the user nearest to each door is determined. A first opening setting function for setting the opening of each door nearest to the user according to the type, and a second for setting the opening of each door based on the detection result in the vehicle position detection unit 17 There are an opening setting function and a third opening setting function for setting the opening of each door based on the detection result in the vehicle speed detection unit 19.

  As an example of the first opening degree setting function of the processing device 9, each door is based on the detection results of the child seat attachment / detachment state detection unit 13 and the occupant type detection unit 15 (that is, the detection results of the occupant type detection means). To determine the occupant type of the nearest user. Here, in the processing device 9, the occupant type detection means in each seat is associated with the nearest door in advance, and stored in advance in, for example, non-volatile memory as table data or the like. When the occupant type is detected, the table data stored in the non-volatile memory is read, and the door associated in advance with the occupant type detection means from which the occupant type is detected is used as the nearest door. to decide. For example, when the passenger in the front passenger seat is determined to be a child, the opening of the front passenger seat is limited to, for example, a maximum of 30 degrees as the nearest door to this, whereas when the passenger in the front passenger seat is determined to be an adult, Set the door opening to the maximum structural angle (no limit).

  As an example of the second opening degree setting function of the processing device 9, based on the detection result of the own vehicle position detection unit 17, when the own vehicle position is, for example, a parking lot at home, the passenger seat door is opened. While the degree is limited to a maximum of 30 degrees, for example, in the case of a company parking lot, the opening degree of the passenger seat door is set to a structural maximum angle (no limit). If the vehicle position is within a certain range from the registered vehicle position coordinates (for example, within a radius of 5 m), the vehicle position is regarded as the same position, and the door opening control condition set together with the vehicle position coordinates is applied. To do. This is because, for example, the maximum position error of D-GPS is about 5 m.

  When the opening set by the first opening setting function and the opening limit set by the second opening setting function are different, for example, the first opening setting function and the second opening setting function A priority order is determined in advance with the opening degree setting function, and any opening degree limit value is applied according to this priority order. Or you may make it employ | adopt the smaller angle among the opening degree limit values set by both the opening degree setting functions.

  Alternatively, the opening is not determined by each of the first opening setting function and the second opening setting function, but based on the combination of the occupant type and the position information by a single opening setting function. The opening degree may be determined. For example, one door opening limit value may be set when both the vehicle position information and the occupant type conditions are satisfied by a logical product (AND). For example, if the position information of the vehicle is a parking lot at home and the passenger in the front passenger seat is a child, the opening of the front passenger door can be limited to a specified angle. Good. In addition, when used in combination with the navigation system, if the occupant is determined to be a child when the vehicle is parked outside the registered location, a small angle is adopted as the opening limit value, or the road information is used on the road. When the vehicle is stopped and the occupant is determined to be a child, it is desirable to set the door opening limit value to a small angle.

  As for the third opening degree setting function of the processing device 9, the first opening degree setting function and the second opening degree function only when the vehicle speed is determined to be below a certain level based on the detection result of the vehicle speed detection unit 19. The opening setting function is enabled.

<Operation>
An example of the operation of the vehicle door opening position control device having the above-described configuration will be described with reference to the flowchart of FIG. The setting of the door opening control condition will be described on the assumption that the door opening control condition input means 1 has already been input and set.

  First, in step S01 in FIG. 3, the processing device 9 determines whether or not each door of the automobile is in a closed state, and determines whether or not the time is suitable as a determination timing of the door opening control condition. to decide. If a positive determination is made in step S01, the process proceeds to the next step S02.

  In step S02, based on the vehicle speed detection result in the vehicle speed detector 19, it is detected whether or not the vehicle speed is below a certain value. In this case, even when the vehicle speed is zero (that is, parked and stopped), it is determined that the vehicle speed is equal to or less than a certain value. If it is determined in step S02 that the vehicle speed is equal to or less than a certain value, the process proceeds to the next step S03.

  In step S03, it is determined whether a condition setting based on vehicle position information already exists. When a positive determination is made in step S03, the condition in which the vehicle position is set based on the information on the vehicle position obtained from the vehicle position detection unit 17 in the next step S04. It is determined whether or not it matches. If a positive determination is made in step S04, the process proceeds to the next step S05.

  In step S05, it is determined whether or not a condition setting based on the occupant type already exists. If a positive determination is made in step S05, information obtained by the child seat attachment / detachment state detection unit 13 or the occupant type detection unit 15 in the next step S06 (that is, detection by the occupant type detection means) Based on the result, it is determined whether or not the passenger type matches the condition setting. If an affirmative determination is made in step S06, the process proceeds to the next step S07, and the occupant type detection means for detecting the occupant type based on the vehicle position information and the occupant type information is detected. Through the door opening control units 7a, 7b,..., The door associated in advance is determined as the nearest door, and the maximum opening of the door is limited to an angle corresponding to the above composite condition. Control the opening of the door.

  If a negative determination is made in step S05 or step S06, the process proceeds to step S08 to perform door opening control under vehicle position information conditions.

  If a negative determination is made in step S03 or step S04, the process proceeds to step S09.

  In step S09, it is determined whether or not a condition setting based on the occupant type already exists. If an affirmative determination is made in step S09, the information obtained by the child seat attachment / detachment state detection unit 13 or the occupant type detection unit 15 in the next step S10 (ie, detection by the occupant type detection means) Based on the result, it is determined whether or not the passenger type matches the condition setting. If a positive determination is made in step S10, the process proceeds to the next step S11 to perform door opening control under the occupant type condition.

  Furthermore, when a negative determination is made in step S01, step S02, step S09, and step S10, the process proceeds to step S12, and the door opening degree control is not performed.

  In this way, it is possible to easily control the opening of the door without using any sonar sensor, so it is not necessary to measure the distance to the obstacle that exists in the direction in which the door opens as in the past. However, the opening degree can be controlled so that the door can be opened and closed safely. Therefore, the cost of the sensor and the cost for mounting the sensor can be reduced.

  Further, it is convenient because the open position of the door can be appropriately controlled by parameters such as the vehicle position and the occupant type.

  Further, since the display unit 3 for confirming and displaying the setting conditions is provided, the setting input operation by the user with the door opening control condition input means 1 is facilitated.
