Description

  The present invention relates to an in-vehicle system that is mounted on a vehicle and activates an imaging device that images the periphery of the vehicle in response to the start of the engine of the vehicle.

  2. Description of the Related Art In recent years, vehicles equipped with a camera system that supports driving by attaching an imaging device (vehicle camera) to a vehicle and displaying an image captured by the vehicle camera on a display device in a vehicle interior have become widespread. For example, there is a camera system that displays a front-rear and left-right image of a vehicle as a bird's-eye view viewed from the viewpoint above the vehicle and displays the image on a display device. A front camera and a side camera that images the side of the vehicle are provided. For example, Patent Document 1 discloses a camera in which a side camera for imaging a side of a vehicle is attached to a door mirror (for example, its bottom surface). Since electric power for driving the side camera is supplied from a battery provided in the vehicle body part, electric wiring (harness) passes from the vehicle body part to the side camera.

  In recent years, with the aim of improving user convenience, a keyless entry system that locks and unlocks the door of a vehicle by remote operation with a keyless remote control and a remote engine start that starts a vehicle engine by remote operation with a starter remote control Systems have been developed and there are vehicles equipped with these systems.

JP 2014-170357 A

  In a vehicle equipped with a camera system, a keyless entry system, and a remote engine start system as described above, the in-vehicle camera is energized and started in response to the start of the engine, and therefore when the engine is started by the remote engine start system. The in-vehicle camera will be activated. Thereby, the vehicle-mounted camera is energized, and noise is generated with the energization. In a keyless entry system, an antenna that receives radio waves transmitted from a keyless remote control may be provided inside the door mirror. In this case, the noise may be superimposed on the radio waves from the keyless remote control. Therefore, there is a problem that radio waves from the keyless remote control cannot be detected normally and the door lock cannot be released. As a countermeasure against this noise, it is conceivable to suppress the noise by using a shield wire for the harness of the in-vehicle camera. However, since the shield wire is used, the cost and the weight are increased. Moreover, since a harness becomes thick and the freedom degree of the routing in a door mirror is reduced, it is desirable to solve without using a shield wire.

  Therefore, the present invention has been created in view of the above-described problems, and the object of the present invention is to properly lock the vehicle door by operating the keyless remote control even when the engine is started by the remote engine start system. It is providing the vehicle-mounted system which can cancel | release.

  An in-vehicle system provided by a first aspect of the present invention is an in-vehicle system that is mounted on a vehicle and activates an imaging device that images the periphery of the vehicle in response to the start of the engine of the vehicle. On the basis of the engine start signal received from the engine, remote start means for starting the engine of the vehicle, engine start detection means for detecting that the engine of the vehicle has started, and engine start is detected by the engine start detection means. When the engine start signal is received from the remote control device, the remote start device determines that the engine has been started, and includes a suppression device that suppresses activation of the imaging device.

  An in-vehicle system provided by a second aspect of the present invention is an in-vehicle system that is mounted on a vehicle and activates an imaging device that images the periphery of the vehicle in response to the start of the engine of the vehicle. Remote start means for starting the engine of the vehicle based on an engine start signal received from the engine, engine start detection means for detecting that the engine of the vehicle is started, and whether the door lock of the vehicle is locked A door lock detecting means for detecting whether the door is unlocked, and when the engine start detecting means detects the start of the engine, when the door lock detecting means detects that the door lock is locked, Deterring means for determining that the engine has been started by the starting means and for suppressing the activation of the imaging apparatus.

  According to the present invention, when the inhibiting means determines that the engine has been started by the remote starting means, the activation of the imaging device is inhibited. As a result, when the engine is started using the remote starting means, the imaging apparatus is not energized, so noise due to energization does not occur, and radio waves from the keyless remote control can be normally detected. Therefore, even when the engine is started by the remote starting means, the vehicle door lock can be normally released.

It is a flowchart which shows starting control of the vehicle-mounted camera which the body ECU which concerns on 1st Embodiment performs. It is a block diagram of the vehicle-mounted system which concerns on 2nd Embodiment. It is a flowchart which shows starting control of the vehicle-mounted camera which body ECU which concerns on 2nd Embodiment performs.

  Embodiments of the present invention will be described in detail with reference to the drawings. FIG. 1 is a diagram showing a configuration of an in-vehicle system 1 according to the first embodiment of the present invention. In FIG. 1, the in-vehicle system 1 includes an electronic key 11, a body ECU (Electronic Control Unit) 12, an engine ECU 13, an in-vehicle camera 14, a display device 15, a video processing unit 16, and an in-vehicle bus 19. Each of these components is connected by an in-vehicle network such as a CAN (Controller Area Network), a FlexRay, a LIN (Local Interconnect Network), and a MOST (Media Oriented Systems Transport). Each of these components exchanges various signals (information and commands) using a predetermined communication protocol when performing various communications with other components. For example, each component connected to the in-vehicle bus 19 transmits and receives signals according to the CAN communication protocol. Note that an in-vehicle bus corresponding to a communication protocol other than CAN may be used.

  The electronic key 11 is a portable device for remotely controlling locking and releasing of the vehicle door lock and starting of the engine, and includes a plurality of buttons for instructing these operations. Therefore, the electronic key 11 has a function as a keyless remote controller for remotely operating the keyless entry system and a starter remote controller for remotely operating the remote engine start system. The electronic key 11 may be composed of two remote controllers, a keyless remote controller and a starter remote controller.

  When the user presses the button of the electronic key 11, the electronic key 11 generates an operation signal based on an operation instruction corresponding to the pressed button. For example, the electronic key 11 is provided with a button (door lock button) for instructing locking of the door lock, and an operation signal for instructing locking of the door lock of the vehicle based on the operation (pressing) of the door lock button. (Door lock locking signal) is generated. In addition, a button (door unlock button) for instructing release of the door lock is provided, and an operation signal (door unlock release) instructing release of the vehicle door lock based on the operation (pressing) of the door unlock button. Signal). Further, a button for instructing engine start by remote operation (remote start button) is provided, and an operation signal (remote start signal; patent for instructing start of the vehicle engine based on operation (pressing) of the remote start button) Corresponding to the “engine start signal” in the claims). When the electronic key 11 generates various operation signals, the electronic key 11 is preset in the electronic key 11 and adds unique information for identifying the electronic key 11 (hereinafter referred to as “electronic key ID”) to the operation signal. Keep it.

  The electronic key 11 transmits the generated operation signal assigned with the electronic key ID as a radio wave having a predetermined frequency.

  The body ECU 12 is an electronic control device that performs various body controls of the vehicle. In addition, the body ECU 12 performs activation control of the in-vehicle camera 14. The startup control of the in-vehicle camera 14 performed by the body ECU 12 will be described later. As shown in FIG. 1, the body ECU 12 includes a keyless control unit 121, a remote start control unit 123, a door lock control unit 125, and a key switch detection unit 126. However, the remote start control unit 123 may be outside the body ECU 12, and at this time, the remote start control unit 123 only needs to be connected to the vehicle-mounted bus 19 and exchange information with the body ECU 12.

  The keyless control unit 121 is an electronic control device that performs various controls related to the keyless entry system, and includes an antenna 122. For example, the antenna 122 is disposed inside a door mirror of a vehicle and receives radio waves having a predetermined frequency. The keyless control unit 121 receives the door lock locking signal transmitted from the electronic key 11 via the antenna 122, confirms the electronic key ID added to the door lock locking signal, and stores the authentication ID stored in advance. When the electronic key IDs match, the door lock locking signal is output to the door lock control unit 125. Similarly, the keyless control unit 121 receives the door lock release signal transmitted from the electronic key 11 via the antenna 122, confirms the electronic key ID added to the door lock release signal, and performs the authentication ID. And the electronic key ID match, the door lock release signal is output to the door lock control unit 125.

  The remote start control unit 123 is an electronic control device that performs various controls related to the remote engine start system, and includes an antenna 124. The antenna 124 receives radio waves having a predetermined frequency. The antenna 124 may be shared with the antenna 122. The remote start control unit 123 receives a remote start signal transmitted from the electronic key 11 via the antenna 124. Then, the electronic key ID given to the remote start signal is confirmed, and when the authentication ID stored in advance matches the electronic key ID given to the remote start signal, the remote start signal is inputted to the engine ECU 13. At this time, when the remote start control unit 123 receives the remote start signal via the antenna 124, for example, it sets a flag (remote start signal reception flag) indicating reception of the remote start signal. The remote start signal reception flag is initialized when the engine stops.

  The door lock control unit 125 performs various controls of the vehicle door lock. The door lock control unit 125 locks the vehicle door according to the door lock locking signal input from the keyless control unit 121 (locks the door lock). Further, the vehicle door is unlocked (the door lock is released) in response to the door lock release signal input from the keyless control unit 121. Further, the door lock control unit 125 detects whether the door lock of the vehicle is locked or released.

  The key switch detection unit 126 detects the state of various key switches of the vehicle. Various key switches include accessory switches, ignition switches, and starter switches. For example, when a user inserts a vehicle key into a key cylinder provided around the steering handle inside the vehicle and rotates the vehicle key, the accessory switch is turned on (ACC-ON) and the ignition switch is turned on in turn (IG -ON), the starter switch can be turned on (ST-ON). Alternatively, the various key switches can be turned on when the user presses a button provided around the steering handle inside the vehicle.

  The engine ECU 13 is an electronic control device that performs various controls related to the engine operation of the vehicle. Various controls related to the engine operation of the vehicle include engine ignition control, fuel control, intake / exhaust control, valve control, and start control. Based on the information of the key switch detection unit 126, the engine ECU 13 starts operation when the ignition switch is on (IG-ON), and further, when the starter switch is on (ST-ON), the starter (not shown) A motor (also called a cell motor) is driven to start the engine. The engine ECU 13 also drives the starter motor to start the engine when a remote start signal is input from the remote start control unit 123. Then, when the engine is operating, the engine ECU 13 ends the fuel injection and stops the engine when the ignition switch is turned off (IG-OFF) based on the information of the key switch detection unit 126. .

  The engine ECU 13 detects the start of the vehicle engine. When the engine ECU 13 detects the start of the engine, the engine ECU 13 outputs the detection result (hereinafter referred to as “start detection signal”) to the body ECU 12. For example, the engine ECU 13 determines that the engine has started when the engine speed is other than 0 [rpm] based on the detection result of a speed sensor (not shown) for detecting the engine speed. To do. Further, it may be determined that the engine has started by detecting the operation of the starter motor. Note that the method by which the engine ECU 13 detects the start of the engine is not limited to the above.

  The in-vehicle camera 14 is an imaging device that captures an image around the vehicle. For example, the in-vehicle camera 14 includes an imaging element such as a CCD or a CMOS, and images a predetermined imaging area at a predetermined frame rate. Examples of the in-vehicle camera 14 include a front camera that captures an image in front of the vehicle, a back camera that captures an image in the rear of the vehicle, and a side camera that captures images on the side of the vehicle. The side camera is attached to a door mirror (for example, the bottom surface) of the vehicle. Note that the mounting positions of these cameras are not limited to those described above. Image data captured by the vehicle-mounted camera 14 is output to the video processing unit 16 via the vehicle-mounted bus 19.

  The display device 15 is constituted by, for example, an LCD (liquid crystal display device) and is installed in a center console portion of the vehicle. The display device 15 is not limited to the LCD, and may be an organic EL display, a plasma display, or the like. Further, the installation position is not limited to the center console portion, and may be in a range that can be seen by the user.

  The video processing unit 16 is an electronic control device that performs various controls related to the display device 15. The video processing unit 16 causes the display device 15 to display image data input from the in-vehicle camera 14. Thereby, the image | video imaged with the vehicle-mounted camera 14 is displayed on the display apparatus 15, and the user can visually recognize the image | video around a vehicle from the inside of a vehicle. Further, the video processing unit 16 controls energization to the in-vehicle camera 14 based on an instruction from the body ECU 12 and controls activation of the in-vehicle camera 14.

  Next, an activation control method for the in-vehicle camera 14 of the in-vehicle system 1 according to the first embodiment configured as described above will be described. FIG. 2 is a flowchart showing activation control of the in-vehicle camera 14 performed by the body ECU 12. It is assumed that the vehicle engine is not started at the start time. Further, when starting the engine in a situation where the user is in the vehicle, the engine is started using the starter switch in the vehicle (by operating the key switch) without using the electronic key 11.

  First, the body ECU 12 determines whether or not the vehicle engine has been started (step S11). Specifically, body ECU 12 determines the start of the engine of the vehicle depending on whether a start detection signal is input from engine ECU 13 or not. At this time, when the body ECU 12 determines that the start detection signal is not input from the engine ECU 13 and the engine has not started, the process returns to step S11, until the start detection signal is input, that is, until the engine starts. Continue monitoring.

  On the other hand, when a start detection signal is input from the engine ECU 13 to the body ECU 12 in step S11 and the body ECU 12 determines that the engine is started, the body ECU 12 then determines whether or not a remote start signal has been received. (Step S12). Specifically, the body ECU 12 confirms the remote start signal reception flag, and if the remote start signal reception flag is set, it is determined that the remote start signal has been received, while the remote start signal reception flag is set. If not, it is determined that the remote start signal has not been received. At this time, if the remote start signal reception flag is set and it is determined that the remote start signal has been received, the body ECU 12 determines that the engine is being started by the remote engine start system, and the video processing unit 16 receives the in-vehicle camera. 14 is instructed not to execute energization. That is, the body ECU 12 suppresses activation of the in-vehicle camera 14 (step S13).

  Thereafter, the body ECU 12 monitors whether or not the door lock is released by the door lock control unit 125 (step S14). For example, when the door unlock button of the electronic key 11 is pressed, the door lock control unit 125 releases the door lock. At this time, since the body ECU 12 detects that the door lock is released by the door lock control unit 125, the body ECU 12 determines that the door lock is released, and energizes the in-vehicle camera 14 to the video processing unit 16. Instruct to start. Thereby, the vehicle-mounted camera 14 starts (step S15). On the other hand, when the release of the door lock by the door lock control unit 125 is not detected, the monitoring is continued until the door lock is released and the activation of the in-vehicle camera 14 is continuously suppressed. Note that when door unlocking is detected, the engine may be stopped and terminated. At this time, the in-vehicle camera 14 is not activated.

  If it is determined in step S12 that the remote start signal reception flag is not set and the remote start signal is not received, the body ECU 12 determines that the engine is not started by the remote engine start system, and the process of step S15 is performed. Then, the video processing unit 16 is instructed to start energization of the in-vehicle camera 14. Thereby, the vehicle-mounted camera 14 starts. For example, when the user turns on the starter switch by operating a key switch in the vehicle and starts the engine, the body ECU 12 does not start the engine by the remote engine start system because the remote start signal reception flag is not set. And the in-vehicle camera 14 is activated. Therefore, in this case, the in-vehicle camera 14 is activated immediately in accordance with the start of the engine.

  After starting the in-vehicle camera 14 in step S15, the body ECU 12 operates the in-vehicle camera 14 until the engine is stopped, specifically, until the ignition is turned off by operating the key switch.

  In this way, the start control of the in-vehicle camera 14 by the body ECU 12 is executed. Note that the start control of the in-vehicle camera 14 by the body ECU 12 is started every time the vehicle engine is stopped.

  From the above, in the in-vehicle system 1 according to the first embodiment of the present invention, the body ECU 12 sends a remote start signal from the electronic key 11 when judging the start of the engine based on the start detection signal from the engine ECU 13. If it has been received, it is determined that the engine has been started by the remote engine start system. When it is determined that the engine is started by the remote engine start system, the video processing unit 16 is instructed not to energize the in-vehicle camera 14 and the activation of the in-vehicle camera 14 is suppressed. As a result, noise due to energization of the in-vehicle camera 14 does not occur, so that the noise is not superimposed on various operation signals (particularly door lock release signals) transmitted from the electronic key 11. Therefore, the in-vehicle system 1 can normally detect the door lock release signal transmitted from the electronic key 11 and reliably lock the vehicle door even after the engine is started by the remote engine start system. It can be canceled.

  Further, since it is not necessary to use a shielded wire or the like for the harness of the in-vehicle camera 14 for noise countermeasures, it is possible to suppress an increase in cost and mass, and to prevent a reduction in the degree of freedom of the arrangement in the door mirror. it can.

  In the first embodiment, the body ECU 12 determines whether or not the remote start signal has been received by checking the remote start signal reception flag. However, the present invention is not limited to this. That is, the method is not limited as long as the body ECU 12 can determine whether or not the remote start signal has been received.

  In the first embodiment, the case where the remote engine start system is mounted in advance in the vehicle and the body ECU 12 includes the remote start control unit 123 has been described as an example. Therefore, the body ECU 12 can determine whether or not the remote start control unit 123 has received a remote start signal from the electronic key 11. However, when a remote engine start system is attached (added) later, the remote start control unit 123 cannot be built in the body ECU 12, and it is determined whether the body ECU 12 has received a remote start signal. I can't judge. Therefore, the body ECU 12 cannot determine whether or not the engine is being started by the remote engine start system based on whether or not the remote start signal is received. Therefore, the engine start determination method by the remote engine start system in this case will be described below as a second embodiment. In addition, about the component same or similar to the vehicle-mounted system 1 which concerns on the said 1st Embodiment, the same code | symbol is attached | subjected and the description is abbreviate | omitted.

  FIG. 3 is a diagram showing a configuration of the in-vehicle system 2 according to the second embodiment of the present invention. In the figure, the in-vehicle system 2 includes a keyless remote control 111, a body ECU 22, an engine ECU 13, a starter remote control 112, a remote start control unit 27, an in-vehicle camera 14, a display device 15, a video processing unit 16, and an in-vehicle bus 19. Configured. Compared with the in-vehicle system 1 (see FIG. 1), the in-vehicle system 2 has a remote start control unit 123 connected to the engine ECU 13 instead of the inside of the body ECU 12.

  The keyless remote control 111 is a portable device for remotely controlling the locking and releasing of the door lock of the vehicle. Compared with the electronic key 11 according to the first embodiment, the keyless remote control 111 is a remote start for instructing the engine start by remote operation. The difference is that no buttons are provided. That is, the keyless remote control 111 is configured to have only the function of the keyless remote control.

  The body ECU 22 is different from the body ECU 12 according to the first embodiment in that it does not include the remote start control unit 123 inside or is not connected via the in-vehicle bus 19. Further, the body ECU 22 is different from the body ECU 12 according to the first embodiment in the engine start determination method by the remote engine start system. Specifically, the body ECU 12 according to the first embodiment checks whether or not the engine has been started by the remote engine start system by checking the remote start signal reception flag when detecting the start of the engine. I was judging. However, when detecting start of the engine, the body ECU 22 according to the second embodiment determines whether the door lock is locked or unlocked by the door lock control unit 125 according to the detection result of the remote engine. It is determined whether or not the engine is started by the start system.

  When the start detection signal is input from the engine ECU 13 and the start of the engine is detected, the body ECU 22 next confirms the detection result by the door lock control unit 125 whether the door lock is locked or released. . If the door lock is locked based on the detection result, it is determined that the engine is started by the remote engine start system, and activation of the in-vehicle camera 14 is suppressed. On the other hand, if the door lock is being released based on the detection result of the door lock control unit 125, it is determined that the engine is not started by the remote engine start system, and the in-vehicle camera 14 is activated.

  The starter remote control 112 is a portable device for remotely operating the remote engine start system, and includes a remote start button provided in the electronic key 11 of the first embodiment. When the user presses the remote start button of the starter remote control 112, the starter remote control 112 generates a remote start signal and transmits it to the remote start control unit 27.

  The remote start control unit 27 corresponds to the remote start control unit 123 according to the first embodiment, and is an electronic control device that performs various controls related to the remote engine start system. The remote start control unit 27 includes an antenna 124 for receiving a signal (remote start signal) transmitted from the starter remote controller 112. Further, unlike the first embodiment, the remote start control unit 27 is directly connected to the engine ECU 13 via a dedicated harness.

  Next, an activation control method for the in-vehicle camera 14 of the in-vehicle system 2 according to the second embodiment configured as described above will be described. FIG. 4 is a flowchart showing start-up control of the in-vehicle camera 14 performed by the body ECU 22. As shown in the figure, it differs from the start control of the in-vehicle camera 14 according to the first embodiment shown in FIG. 2 in that step S12 is replaced with step S22. It is assumed that the vehicle engine is not started at the start time. Further, it is assumed that the vehicle door lock is locked when the user is outside the vehicle, and the vehicle door lock is released when the user is inside the vehicle.

  In step S11, when the body ECU 22 receives the start detection signal from the engine ECU 13 and detects the start of the engine, the door lock control unit 125 then detects whether the door lock is being locked or released. The result is confirmed (step S22). At this time, if the door lock is locked, the body ECU 22 determines that the engine is being started by the remote engine start system, proceeds to the process of step S13, and suppresses the activation of the in-vehicle camera 14. Thereafter, the processes of steps S14 and S15 are executed. On the other hand, if the door lock is being released in step S22, the body ECU 22 determines that the engine has not been started by the remote engine start system, proceeds to the processing in step S15, and activates the in-vehicle camera 14. Note that when door unlocking is detected, the engine may be stopped and terminated. At this time, the in-vehicle camera 14 is not activated.

  From the above, in the in-vehicle system 2 according to the second embodiment of the present invention, when the body ECU 22 determines the start of the engine based on the start detection signal input from the engine ECU 13, the door lock is locked. If it is, it is determined that the engine is started by the remote engine start system. When the body ECU 22 determines that the engine is started by the remote engine start system, the body ECU 22 instructs the video processing unit 16 not to energize the in-vehicle camera 14 and suppresses the activation of the in-vehicle camera 14. I did it. As a result, noise due to energization of the in-vehicle camera 14 does not occur, so that the noise is not superimposed on various operation signals (particularly door lock release signals) transmitted from the keyless remote control 111. Therefore, the in-vehicle system 2 can normally detect the door lock release signal transmitted from the keyless remote control 111, and even after the engine is started by the remote engine start system, the vehicle door lock can be surely performed. It can be canceled.

  Further, as in the first embodiment, since it is not necessary to use a shielded wire or the like for the harness of the in-vehicle camera 14 for noise countermeasures, it is possible to suppress an increase in cost and mass, and to arrange a door mirror. It is possible to prevent a decrease in the degree of freedom.

  In the second embodiment, when the body ECU 22 detects the start of the engine, when the door lock state is locked based on the detection result of the door lock control unit 125, the engine is started by the remote engine start system. Although the case where it is determined to be present has been described as an example, it is not limited thereto. For example, the body ECU 22 is further provided with a shift lever detection unit (not shown) for detecting the position of the shift lever. When the engine is started, the shift lever is in the parking range and the door lock is locked. In the state, it may be determined that the engine is started by the remote engine start system. Alternatively, the body ECU 22 includes a door opening / closing detection unit (for example, a courtesy switch) (not shown) that detects opening / closing of the door, and when the body ECU 22 detects the start of the engine, the body ECU 22 Using the detection result of the lock control unit 125, if the door opening / closing detection unit has never detected the opening / closing of the door after the previous door lock, it is determined that the engine has been started by the remote engine start system. May be. Furthermore, when the start of the engine is detected using the position information of the shift lever by the shift lever detection unit, the door opening / closing detection unit once opens / closes the parking range and after the previous door lock is locked. May not be detected, it may be determined that the engine is started by the remote engine start system.

  In the first embodiment and the second embodiment described above, a vehicle equipped with a keyless entry system has been described as an example. Is possible. The key-free system has a function of a keyless entry system, and the user has an electronic key (key-free remote control) and approaches the vehicle, and a door lock locking / unlocking switch (request switch) provided on the vehicle door. The function of locking and releasing the door lock of the vehicle by pressing is provided. Furthermore, when the user owns the key-free remote control and only approaches the predetermined range around the vehicle, the vehicle door lock is automatically released, and when the user goes out of the predetermined range, the vehicle door lock is automatically set. It may have a function of locking. In this case, instead of the keyless control unit 121, an electronic control device (key-free control unit) that performs various controls related to the key-free system is used.

  For example, in response to pressing of the request switch, the key-free control unit transmits a request signal for determining whether or not the key-free remote control exists in the vicinity of the vehicle, and the key-free remote control receives the request signal. Then, the electronic key ID is transmitted. At this time, in the conventional technology, when the engine is started by the remote engine start system, the noise is superimposed on the electronic key ID transmitted from the key-free remote controller due to the influence of noise caused by energization of the in-vehicle camera 14. End up. As a result, the key-free control unit cannot normally detect the electronic key ID, so that the key-free remote controller cannot be authenticated and the door lock may not be released. However, when the present invention is applied, noise accompanying energization of the in-vehicle camera 14 does not occur, so that the key-free control unit can normally detect the electronic key ID, and the key-free remote control can be authenticated. Thereby, the door lock can be normally released.

  Note that the in-vehicle system according to the present invention is not limited to the above-described embodiment, and the specific configuration of each part can be variously modified without departing from the scope of the claims of the present invention. it can.
