Description

  The present invention relates to a remote operation system that detects a movement of a portable device with a motion sensor and remotely operates a control target on condition that the detection value of the motion sensor reaches a determination threshold value.

  Conventionally, when a movement of a portable device is detected by an acceleration sensor and the detected value of the acceleration sensor reaches a determination threshold value, an affirmative determination is made that there is a specific operation stored in advance in the portable device, and the portable device is transferred to the vehicle. There has been proposed a remote operation system that outputs an operation completion and remotely operates the in-vehicle device in response to the output.

  For example, in the technique of Patent Document 1, the swing operation of the portable device is reflected in the open / close control of the slide door, and in the technique of Patent Document 2, the hitting operation of the portable device is reflected in the door locking / unlocking control.

  In the configuration in which the target (control target) is operated when one motion operation can be detected, there is a possibility of causing a malfunction by a similar operation. Of course, when a complicated operation is requested from the user in order to avoid a malfunction, the operability is inferior.

  The present invention has been made paying attention to such problems, and an object of the present invention is to provide a remote operation system that enables both an operational feeling and an operation cancelability.

  A remote operation system that solves the above-described problems is a remote operation system that remotely detects a movement of a portable device using a motion sensor and that remotely operates a control target on the condition that the detection value of the motion sensor has reached a determination threshold. The gist of the invention is that it includes a control means for remotely operating a control target in response to a set operation in which a main operation by machine movement and a sub-operation with less user load than the main operation are combined.

  According to this configuration, a feeling of operation can be obtained by including the main operation in the set operation, and cancelability can be provided by another operation by combining the sub operation with the main operation. Therefore, both the operational feeling and the operation cancelability can be achieved.

  In the remote operation system, the control unit may remotely operate a control target in response to the set operation in which the main operation is sandwiched between two sub-operations that are the same or different from each other.

  According to this configuration, the set operation in which the main operation is sandwiched between two sub-operations is defined, the prior sub-operation has the meaning of prior confirmation of the operation intention, and the subsequent sub-operation has the meaning of final confirmation of the operation intention. Can be made.

  For the above-mentioned remote operation system, before the detection value of the final operation that defines the set operation reaches the determination threshold, the control target is remotely operated on the condition that the detection value of the final operation has reached the determination threshold later. It is good also as providing the alerting | reporting means to perform the prior notice to suggest.

  According to this configuration, prior notification is performed before the detection of the final operation, so that the user can know that the remote operation can be performed through the final operation, and the remote operation can be performed through other operations. Can be canceled.

In the remote operation system, the final operation may be a stationary operation for a fixed time.
According to this configuration, the user can easily cancel the remote operation by receiving a prior notification and performing a motion other than the stationary motion when the user does not intend to operate.

  According to the present invention, it is possible to achieve both operational feeling and operation cancelability.

The block diagram which shows the structure of a remote control system. The perspective view which shows a series of motion operation for every step of step 1-step 3. FIG.

Hereinafter, an embodiment of the remote control system will be described.
As shown in FIG. 1, the remote operation system 1 can perform bidirectional wireless communication between the portable device 2 and the vehicle 3 and can perform unidirectional wireless communication with the portable device 2 as a transmission side. is there. For bidirectional wireless communication, LF (low frequency) band radio waves and UHF (ultrahigh frequency) band radio waves are used, and for unidirectional wireless communication, UHF band radio waves are used.

  The portable device 2 includes an LF reception circuit 21, a microcomputer 22, a UHF transmission circuit 23, and an acceleration sensor 24. The LF receiving circuit 21 can receive a request signal transmitted from the vehicle 3 as an LF band radio wave. When receiving the request signal, the LF reception circuit 21 generates a reception signal by electrical processing such as demodulating the signal, and outputs the reception signal to the microcomputer 22.

  The microcomputer 22 includes a nonvolatile memory 22a. An ID (identification) unique to the portable device 2 is stored in the memory 22a. When the reception signal is input from the LF reception circuit 21, the microcomputer 22 generates an original signal including the ID in order to respond to the request signal, and outputs the original signal to the UHF transmission circuit 23. The UHF transmission circuit 23 generates a response signal by electrical processing, such as modulating the original signal input from the microcomputer 22, and transmits the response signal to the outside of the portable device 2 as a radio wave in the UHF band.

  The acceleration sensor 24 is a medium for detecting the acceleration applied to the portable device 2 and outputs an acceleration detection value to the microcomputer 22. When the detected value of the acceleration sensor 24 reaches the determination threshold value, the microcomputer 22 determines that a specific operation stored in advance has been performed, generates an original signal including a code indicating the operation completion and the ID, This original signal is output to the UHF transmission circuit 23. In this case, the UHF transmission circuit 23 electrically processes the original signal and transmits an operation completion signal to the outside of the portable device 2 as a radio wave in the UHF band.

  The specific operation includes a stationary operation for about 1 second. This operation is defined as the first sub-operation. When a stationary motion of 1 second or longer is detected, an operation completion signal indicating completion of the first sub-operation is transmitted from the portable device 2.

  The specific operation includes a knee bending operation (bending / extending operation) in which both knees are bent and extended. This operation is defined as the main operation. When the knee bending motion is detected, an operation completion signal indicating completion of the main operation is transmitted from the portable device 2.

  Further, the specific operation includes a stationary operation for about 1.5 seconds. This operation is defined as the second sub-operation. When a stationary motion of 1.5 seconds or longer is detected, an operation completion signal indicating completion of the second sub-operation is transmitted from the portable device 2.

  As the first or second sub-operation (stationary operation), an operation with less user burden than the main operation (knee bending operation) is preferably employed. The acceleration sensor 24 corresponds to a motion sensor.

  The vehicle 3 includes an LF transmitter 31, a UHF receiver 32, a verification ECU (Electronic Control Unit) 33, a hazard lamp 34, and a buzzer 35. The LF transmitter 31 receives a control by the verification ECU 33 and transmits a request signal to an outdoor LF area whose separation distance from each door (including a driver's seat door and a slide door) is about 1 meter or less. When the portable device 2 enters the outdoor LF area, a response signal is returned from the portable device 2 in response to the request signal. The UHF receiver 32 can receive an operation completion signal in addition to the response signal from the portable device 2.

  The verification ECU 33 includes a non-volatile memory 33a. In the memory 33a, the ID of the portable device 2 suitable for the vehicle 3 is registered as a reference ID. The verification ECU 33 transmits a request signal from the LF transmitter 31 in order to monitor the approach of the portable device 2. When the response signal is received by the UHF receiver 32 along with the transmission of the request signal, the verification ECU 33 performs verification with the reference ID for the ID included in the signal.

  If the ID matches, the verification ECU 33 permits the doors to be unlocked, and turns on the hazard lamp 34 when an operation completion signal indicating the completion of the first sub-operation is received in this state.

In addition, when the operation completion signal indicating the completion of the main operation is received, the verification ECU 33 turns on the hazard lamp 34 and sounds the buzzer 35.
Furthermore, when the operation completion signal indicating the completion of the second sub-operation is received continuously, the verification ECU 33 operates the actuator to open the slide door. In this example, when the user who has the portable device 2 performs a setting operation by “first sub operation → main operation → second sub operation” in the outdoor LF area, the slide door is automatically opened. The sliding door corresponds to the control target, and the verification ECU 33 corresponds to the control means. Both the hazard lamp 34 and the buzzer 35 correspond to notification means.

Next, the operation of the remote operation system 1 will be described.
As shown in FIG. 2, first, in step 1, the user who has the portable device 2 enters the outdoor LF area and stops for about 1 second. When a stationary motion of 1 second or longer is detected, an operation completion signal indicating completion of the first sub-operation is transmitted from the portable device 2, and when this signal is received by the vehicle 3, the hazard lamp 34 is turned on. The The first sub-operation has the meaning of prior confirmation of the operation intention, and the lighting of the hazard lamp 34 has the meaning of motion detection activation (recognized here that the operation can be performed). If the first sub-operation is not completed, the hazard lamp 34 is continuously turned off.

  In step 2, the user performs a knee bending operation. When the knee bending motion is detected, an operation completion signal indicating completion of the main operation is transmitted from the portable device 2, and when this signal is received by the vehicle 3, the hazard lamp 34 is turned on and the buzzer 35 is turned on. It is ringed. The lighting of the hazard lamp 34 accompanied by the ringing of the buzzer 35 has the meaning of a prior notification that suggests that the sliding door will be opened on the condition that the second sub-operation is detected later. When the main operation is not completed, the hazard lamp 34 is turned off. In this case, the user who intends to perform the operation starts the motion operation again from Step 1.

  In step 3, the user stands still for about 1.5 seconds in the outdoor LF area. When a stationary motion of 1.5 seconds or more is detected, an operation completion signal indicating the completion of the second sub-operation is transmitted from the portable device 2, and when this signal is received by the vehicle 3, the sliding door is opened. It is. The second sub-operation has the meaning of final confirmation of the operation intention. If the second sub-operation is not completed, the hazard lamp 34 is turned off. In this case, the user who intends to perform the operation starts the motion operation again from Step 1.

As described above, according to the present embodiment, the following effects can be obtained.
(1) A feeling of operation can be obtained by including the main operation (knee bending motion) in the set operation (series of motion operations), and by combining the sub operation (stationary motion for a certain period of time) with the main operation (knee bending motion). Cancelability can be provided by other operations (walking or the like). Therefore, both the operational feeling and the operation cancelability can be achieved.

  (2) A set operation (a series of motion operations) sandwiching the main operation (knee bending motion) between two sub-operations (stationary motion for a certain period of time) is specified, and the previous sub-operation (stationary motion for about 1 second) is specified. The meaning of prior confirmation of the operation intention can be given, and the meaning of the final confirmation of the intention of operation can be given to the subsequent sub-operation (still operation for about 1.5 seconds).

  (3) Prior notification (lighting of the hazard lamp 34 accompanied by the ringing of the buzzer 35) is performed before detection of the final operation (still operation for about 1.5 seconds), whereby the user can perform the final operation (about 1.5 seconds). It is possible to know that the remote operation becomes possible via a stationary operation for a second), and it is possible to cancel the remote operation via another operation (walking or the like).

  (4) In relation to (3) above, prior notification (with buzzer 35 ringing) at the stage when the last operation (knee bending operation) of the final operation (approximately 1.5 seconds of stationary operation) is detected. The hazard lamp 34 is turned on), so that the user can cancel the remote operation by performing another operation (walking or the like) with a relatively long time.

  (5) The final operation that defines the set operation (a series of motion operations) is a stationary operation for a fixed time. According to this configuration, the remote operation can be easily performed by receiving a prior notice (lighting of the hazard lamp 34 accompanied by the sound of the buzzer 35), and when the user does not intend to operate, but performs some movement (walking, etc.) other than stationary. Can be canceled.

In addition, the said embodiment can also be changed and actualized as follows.
-The main operation in a series of motion operations is not limited to knee bending (bending and stretching). It may be a swinging operation or hitting operation of the portable device 2. The magnitude of acceleration, the application time of acceleration, the number of operations, or the like is compared with a determination threshold value.

The first or second sub operation in the series of motion operations is not limited to a stationary operation for a fixed time.
The first sub-operation and the second sub-operation may be the same operation (for example, both are stationary operations for about 1 second).

  The first sub-operation and the second sub-operation may be defined as operation times that are the same type of operation (for example, a stationary operation) and that are different from each other. The operation time of the first sub operation may be longer or shorter than the operation time of the second sub operation.

-The 1st suboperation is good also as an approach operation to the outdoor LF area.
-When the set operation includes a stationary operation, the stationary time may be arbitrarily changed.
-If a series of motion operations (set operations) is a combination of a main operation (for example, knee bending motion) and a sub-operation (for example, a stationary motion for a certain period of time) with less user load than the main operation, the above operation is performed. It is not limited to the combination of “first sub operation → main operation → second sub operation”. Combination of “sub operation (for example, stationary motion for a certain time) → main operation (for example, knee bending motion)” or “main operation (for example, knee bending motion) → sub operation (for example, stationary motion for a certain time) May be combined.

  Instead of the microcomputer 22 of the portable device 2 comparing the detection value of the acceleration sensor 24 with the determination threshold value, the verification ECU 33 of the vehicle 3 receives the transmission signal from the portable device 2 and compares the detection value of the acceleration sensor 24 with the determination threshold value. However, when the verification ECU 33 determines that a specific operation has been performed, a configuration in which the control target is remotely operated may be employed.

-The controlled object is not limited to sliding doors. The present invention may be applied to a remote operation system that opens a back door of a vehicle or a door of a building by a motion operation.
Next, a technical idea that can be grasped from the above embodiment and another example will be described.

(A) In the remote operation system, the notification means performs prior notification when the detection value of the operation immediately before the final operation has reached the determination threshold.
According to this configuration, prior notification is performed when the operation immediately before the final operation is detected, so that the user can cancel other remote operations by performing other operations within a relatively long time. it can.
