Description

  The present invention relates to a vehicle door control device that automatically opens and closes a door of a vehicle.

  When getting on and off the vehicle, the door is opened and closed. If there is a disturbance such as wind when the door is opened and closed, the door is overloaded. If the door is opened and closed under such a load, a large force is required to open and close the door. Therefore, even when the disturbance (air flow) is large, the door can be opened and closed with a light load. When an automatic door is used, the vehicle door can be automatically opened and closed as much as possible. A control device has been devised (see Patent Document 1).

  In addition, a swing door automatic door opening device that can prevent the swing door from coming into contact with an obstacle whose surface is a mirror surface with high accuracy by using a combination of two sensors, laser and sonar, has been devised. (See Patent Document 2).

  Also, an automatic door operation device for a vehicle has been devised that automatically opens a door only while the user is in contact with an input unit that allows the user to input a command for automatically opening the door of the vehicle (Patent Document). 3).

Japanese Patent No. 424429 JP 2013-010384 A JP 2014-201966 A

  In addition to the air volume, the disturbance includes the influence of vehicle inclination (front-rear direction or left-right direction of the vehicle) caused by stopping on a slope. Depending on the combination of the vehicle inclination direction and the door opening / closing direction, a large force is required to open and close the door. In Patent Document 1, only the air volume is cited as a disturbance, and there is no disclosure or suggestion of control corresponding to the inclination of the vehicle.

  In Patent Document 2, the accuracy of the door opening control is improved, but two sensors, a laser and a sonar, are required, and the cost of the apparatus increases. Also, the obstacle detection process becomes complicated.

  In Patent Literature 3, the ID of the portable key held by the user is checked before the automatic opening operation or the automatic closing operation. However, when the passenger is performing the automatic opening operation or the automatic closing operation, Since the operation can be continued even if the vehicle is separated from the vehicle, it is not preferable in terms of security.

  In view of the above problems, an object of the present invention is to provide a vehicle door control device that improves user convenience and security.

  A vehicle door control device for solving the above problems includes a door provided in a vehicle, a drive unit that opens and closes the door, an operation input unit that performs an operation input for the user to open and close the door, and a user A transmitting unit that transmits a request signal to a portable device possessed, a receiving unit that receives a response signal transmitted from the portable device in response to the request signal, an ID code included in the response signal, and a master code stored in advance A determination unit that determines whether the duration of the operation input exceeds a predetermined threshold when the operation input is performed and the verification is correctly performed, and a determination unit , When it is determined that the duration does not exceed the threshold, the automatic closing operation that drives the drive unit so that the door automatically moves from the fully open position toward the fully closed position, or the door is fully closed from the fully closed position. An automatic opening operation that drives the drive unit to move automatically toward the position is performed. On the other hand, when the determination unit determines that the duration exceeds the threshold, the operation is performed only while the operation input is continued. In accordance with the input, the control unit performs an auxiliary operation to drive the drive unit so that the door automatically moves toward the fully open position or the fully closed position, and the verification is correctly performed during the auxiliary operation. An output unit that outputs warning information reflecting that the verification has not been performed correctly.

  When a passenger who does not have a portable device is performing an assisting action beside the user who has the portable device, it is not preferable for the user to leave the vehicle. The user needs to grasp the passenger's behavior. With the above configuration, it is possible to issue an instruction to stop the auxiliary operation according to the state around the vehicle and the passenger's behavior during the auxiliary operation. In addition, security can be improved by preventing passengers (may be third parties) from entering the vehicle or operating the vehicle's switch, such as operating the vehicle's switch, during assistance operations. To do. Furthermore, the door can be automatically opened and closed without being affected by disturbance (air volume, vehicle body inclination).

  The door lock device 23 includes a known door lock mechanism and an actuator such as a motor, and drives the motor so as to enter a locked state or an unlocked state based on a control command from the door ECU 21.

  As the open switch 24 and the close switch 25, for example, push button type switches are used. The door 20 is automatically opened and closed based on the operation mode of these switches.

  The door handle 26 includes an LF transmitter 26a, a sensor 26b, and a switch 26c. The LF transmission unit 26 a has the same configuration as the vehicle interior LF transmission unit 16. When the vehicle is parked, a detection area corresponding to the arrival distance of the request signal is formed around the door 20, and it is possible to detect which door the user holding the portable device 40 has approached. The door handle 26 also operates as an antenna of the LF transmission unit 26a.

  The sensor 26b uses a known touch sensor, and when the user holding the portable device 40 detects that the door handle 26 has been touched, the door ECU 21 issues a control command to perform a predetermined operation (for example, unlocking). Output. When the switch 26c uses a known push switch and detects that the user carrying the portable device 40 has operated, the door ECU 21 outputs a control command to perform a predetermined operation (for example, locking). The sensor 26b and the switch 26c correspond to the operation input unit of the present invention.

  The back door 30 is a flip-up or side-opening door for opening the rear part of the vehicle. The back door 30 includes a back door ECU 31, a back door drive unit 32 (drive unit of the present invention) connected to the back door ECU 31, a back door lock device 33, and a back door provided outside the vehicle compartment of the back door 30.

An RF transmission unit 45 (a portable device side transmission unit of the present invention) that transmits a response signal including the response signal.

  The control unit 41 acquires the reception signal of the LF reception unit 44, determines whether or not the request signal is received, generates a response signal, and transmits the response signal from the RF transmission unit 45.

The operation unit 42 includes, for example, a push switch group serving as a trigger for using a remote keyless entry (RKE) function. When the user operates the operation unit 42, a command signal (RKE command) requesting to perform an operation according to the operation mode is transmitted from the RF transmission unit 45 while the push switch of the operation unit 42 is being operated. Examples of the RKE command include the following.
-Door lock / door unlock: Lock / unlock or open / close the door 20.
-Back door locking / back door unlocking: unlocking / unlocking or opening / closing the back door 30.

  As the portable device 40, in addition to the smart key described above, a tablet-type terminal represented by a well-known smartphone (a general term for a portable information terminal equipped with a touch panel on a display portion such as a liquid crystal display and operated by a finger), a mobile phone Such a mobile communication terminal may be used.

  The door opening / closing control process that is stored in the memory 12 of the verification ECU 10 and executed by the CPU 11 at a predetermined timing will be described. In addition, since this process is each performed about the door 20 and the back door 30, the door 20 is mentioned as an example. First, the presence / absence of a user operation input by the sensor 26b, the switch 26c, the open switch 24, the close switch 25, and the operation unit 42 of the portable device 40 (hereinafter collectively referred to as “operation input unit”) is determined.

  The configuration in which the sensor 26b, the switch 26c, the open switch 24, and the close switch 25 are used as the operation input unit is “the operation input unit is provided on at least one of the vehicle indoor side and the vehicle outdoor side”. is there. With this configuration, you can open the door before boarding the vehicle, close the door after getting on (sitting), open the door to get off, or close the door after getting off. Auxiliary actions can be performed even in situations.

  The configuration using the above-described operation unit 42 as an operation input unit is as follows: “The operation input unit is provided in a portable device, and the portable device includes a portable device-side transmission unit that transmits a state of a user's operation input to the operation input unit. The receiving unit receives the operation input state ”. With this configuration, the auxiliary operation can be performed even when the door handle cannot be operated, such as when the user has a baggage in both hands.

  When an operation input is detected (S11: Yes), a request signal is transmitted via the vehicle interior LF transmitter 16 and the LF transmitter 26a (S12). Thereafter, a response signal from the portable device 40 is awaiting reception. At this time, the duration of the operation input is measured. Thereafter, the measurement is stopped when no operation input is detected. If the response signal is not received within a predetermined time, this process is terminated.

  When the response signal is received via the RF receiver 15 (S13: Yes), the ID code included in the response signal is collated with the master code stored in the memory 12 (S14). If not correctly collated (S15: No), this process is terminated.

  On the other hand, when the collation is correctly performed (collation normality, S15: Yes), it is determined whether or not the auxiliary operation is set. The setting is performed by the user using at least one of the operation input units. The setting contents are stored in the memory 12. When the auxiliary operation is not set (S16: No), the normal operation (details will be described later) is performed (S20).

  The configuration capable of setting whether or not to perform the above-described auxiliary operation is “having a setting unit that sets whether or not the user performs the auxiliary operation”. With this configuration, it is possible to respond to a request from a user who does not want to perform an auxiliary operation.

  On the other hand, when it is set to perform the auxiliary operation (S16: Yes), the operation mode of the operation input unit is determined based on the operation input duration (S17). When the duration does not exceed the threshold, that is, when the sensor continues to be touched, when the switch is kept pressed, or when the same RKE command is continuously received does not exceed the threshold (S18: No) ), Normal operation is performed (S20).

  On the other hand, when the duration exceeds the threshold value, that is, when the time of touching the sensor exceeds the threshold value (sometimes referred to as “long touch”), or when the switch is kept pressed or the same time When the time when the RKE command is continuously received exceeds the threshold (may be referred to as “long press”) (S18: Yes), the auxiliary operation process is executed (S19, described later).

The normal operation can be exemplified as follows.
When the sensor 26b or the open switch 24 is operated, when the door lock device 23 is in the locked state (fully closed state), the door is unlocked, and then the door 20 is automatically moved from the fully closed position toward the fully opened position. A control command is output to the door ECU 21 so as to perform an automatic opening operation for driving the door drive unit 22 to move.
-When the switch 26c or the closing switch 25 is operated and the door 20 is in a fully open state (not necessarily in the fully open state), the door 20 is automatically moved from the fully open position (or the current position) to the fully closed position. When the door 20 is moved to the fully closed position, a control command is output to the door ECU 21 so that the door lock device 23 is locked. The door lock device 23 may not be locked.

When the operation unit 42 is operated, the following operation is performed according to the content of the RKE command received via the RF receiving unit 15.
-Door locking: A control command is output to the door ECU 21 so that the door lock device 23 is locked.
-Door unlocking: A control command is output to the door ECU 21 so that the door lock device 23 is unlocked.
-Door open: The same as when the sensor 26b or the open switch 24 is operated.
-Door closing: The same as when the switch 26c or the closing switch 25 is operated.

An auxiliary operation process corresponding to step S19 of FIG. 2 in FIG. 3 will be described. First, an auxiliary operation as exemplified below is started (S31).
When the operation continuation time of the sensor 26b or the open switch 24 exceeds the threshold value, or when the continuation time of receiving the RKE command instructing “door unlocking” from the portable device 40 exceeds the threshold value, the door lock When the device 23 is in the locked state, it is in the unlocked state, and a control command is output to the door ECU 21 so as to perform an automatic opening operation.

  The above-described configuration is “the control unit unlocks the door when the door is in a locked state when performing an auxiliary operation for automatically moving the door toward the fully open position”. With this configuration, since the user can perform the unlocking operation and the operation for the auxiliary operation with one operation, the convenience for the user is improved.

When the operation duration of the switch 26c or the closing switch 25 exceeds the threshold value, or when the duration time when the RKE command for instructing “door lock” is received from the portable device 40 exceeds the threshold value, the automatic closing operation When the door 20 is fully closed, a control command is output to the door ECU 21 so that the door lock device 23 is locked. The door lock device 23 may not be locked.

  Next, it is determined whether or not the operation of the operation input unit is continued. When the operation is not continued (S32: No), the auxiliary operation is stopped (S38). That is, a control command is output to the door ECU 21 so as to stop the operation of the door drive unit 22. The door 20 stops at the position when the hand is released from the switch or sensor. Then, this process is complete | finished.

  On the other hand, when the operation continues (S32: Yes), a request signal is transmitted via the vehicle interior LF transmitter 16 and the LF transmitter 26a (S33). Thereafter, a response signal from the portable device 40 is awaiting reception.

  When the response signal is received via the RF receiver 15 (S34: Yes), the ID code included in the response signal is collated with the master code stored in the memory 12 (S35). When not correctly collated (S36: No), for example, warning information including that the collation was not correctly performed is output to the in-vehicle LAN 50 via the communication I / F 14 (S37).

  When the lamp ECU 60 acquires the warning information, the lamp ECU 60 lights or blinks at least one of the lamp devices 61 in a predetermined pattern. When the horn ECU 70 acquires the warning information, the horn ECU 70 causes the horn 71 to sound. You may display a message on the display part of another vehicle-mounted apparatus, or may output a voice message.

  Next, the auxiliary operation is stopped (S38). Then, this process is complete | finished. The configuration of steps S33 to S38 is “If the verification is not performed correctly when the auxiliary operation is performed, the control unit stops the auxiliary operation”. With this configuration, by stopping the door opening / closing operation, the door opening / closing operation continues against the user's intention, and it is possible to prevent a person from being left behind in the vehicle compartment or the door from contacting surrounding objects. . In addition, the user can be alerted to perform an auxiliary operation responsibly.

  On the other hand, when it collates correctly (collation normality, S36: Yes), it returns to step S32 and it is determined whether operation is continuing.

Specifically, the configuration of the present invention operates as follows.
-When contact is detected with the sensor 26b by the user, such as when approaching the vehicle, or when the RKE command "door unlocking" is received, it is determined that neither "long touch" nor "long press" is detected. When the collation is normal, the door lock device 23 is unlocked and the door drive unit 22 is automatically opened to the fully open position. On the other hand, when it is determined as “long touch” or “long press” and the collation is normal, the door lock device 23 is unlocked, and the door is driven only during “long touch” or “long press”. The part 22 is opened (auxiliary operation).

-When the user is seated and operates the closing switch 25, it is determined that it is not "long press", and when the collation is normal, the door driving unit 22 is automatically closed and fully closed, The door lock device 23 is locked. On the other hand, when it is determined as “long press” and the collation is normal, the door drive unit 22 is closed (auxiliary operation) only while the user is pressing the close switch 25.

When the user operates the open switch 24 to get out of the vehicle, it is determined that it is not “long press”, and when the collation is normal, the door lock device 23 is set in the unlocked state, and the door drive unit 22 is automatically opened to the fully open position. On the other hand, when it is determined as “long press” and the collation is normal, the door lock device 23 is unlocked, and the door drive unit 22 is opened (auxiliary only while the user is pressing the open switch 24). Operation).

・ When the operation of the switch 26c by the user is detected, such as after getting off, or when the RKE command “door lock” is received, it is determined that it is not “long press”, and the door is driven when the collation is normal After the part 22 is automatically closed and fully closed, the door lock device 23 is locked. On the other hand, when it is determined as “long press” and collation is normally performed, the door drive unit 22 is closed (auxiliary operation) only during “long press”.

・ When the contact to the sensor 36b by the user is detected or the RKE command “back door unlock” is received, it is determined that neither “long touch” nor “long press” is detected, and the verification is normal. At that time, the back door lock device 33 is unlocked, and the back door drive unit 32 is automatically opened to the fully open position. On the other hand, when it is determined as “long touch” or “long press” and the collation is normal, the back door lock device 33 is unlocked, and the back is locked only during “long touch” or “long press”. The door drive unit 32 is opened (auxiliary operation).

-When the operation of the switch 36c by the user is detected while the back door is open, or when the RKE command "lock back door" is received, it is determined that it is not "long press" and the collation is normal. After the back door drive unit 32 is automatically closed and fully closed, the back door lock device 33 is locked. On the other hand, when it is determined that “long press” and the collation is normal, the back door driving unit 32 is closed (auxiliary operation) only during “long press”.

  Thereby, the user can open and close the door 20 or the back door 30 by a desired opening degree without being affected by the gradient or the air volume in any situation. In addition, when a user (portable device 40) leaves | separates from a vehicle at the time of assistance operation | movement and collation is no longer performed normally, assistance operation | movement is stopped. The opening degree of the door 20 or the back door 30 maintains the state when the auxiliary operation is stopped.
