Description

  The present invention relates to a power switch device operated when turning on / off a power supply of an electrical equipment.

  2. Description of the Related Art Conventionally, an ignition switch device is provided in a vehicle as an operation input system device that is operated when a stop engine is operated or when the operation engine is stopped. This type of ignition switch device inserts the key plate of the vehicle key (mechanical key) into the key cylinder installed on the instrument panel in the car and turns it so that if the vehicle key is a regular one, The key rotation operation is allowed, and the mechanical key can be operated to the operation positions of the off position, the ACC position, the IG on position, and the engine start position. When the mechanical key at the off position is turned to the engine start position, the engine is activated, and when the mechanical key at the IG on position is turned to the off position, the engine is stopped.

  Also, in recent years, in order to improve convenience during door lock locking / unlocking operation and engine start / stop operation, an electronic key capable of transmitting a key-specific ID code by wireless communication is used as a vehicle key. Equipped with an electronic key system that does not require actual key operation during door lock locking / unlocking operation or engine start / stop operation by automatically transmitting the ID code to the vehicle wirelessly and performing key verification (wireless ID verification) Vehicles are increasing. This electronic key system takes a communication form in which a request for an ID reply is periodically sent from the vehicle, and when this request is received by the electronic key, an ID code specific to the key is returned to the vehicle in response thereto.

  One type of electronic key system is a one-push start system that can start an engine only by pressing, for example, a pressing-type (push-type) engine switch installed on an instrument panel in a vehicle. In this one-push start system, if the engine switch is pressed while the brake pedal is depressed when the engine is stopped and the wireless ID verification between the electronic key and the vehicle is established, Thus, when the engine switch is pressed while the engine is operating when the vehicle is stopped, the engine that has been operating until then is stopped.

  An example of this type of one-push start system is disclosed in, for example, Patent Document 1. FIG. 10 shows an example of the one-push start system 24 disclosed in Patent Document 1. In the engine start / stop switch device 81 that is an operation input system device of the one-push start system 24, as described above, There are provided an engine switch 82 used as an operation part in the stop operation, and a power supply ECU 83 that controls (manages) power on / off of various electrical devices installed in the vehicle. The engine switch 82 and the power supply ECU 83 are provided separately as parts, and are connected via a plurality of harnesses 84 serving as transmission paths for various signals.

  The engine switch 82 is provided with a pressing operation portion 85 as an operation location of the engine switch 82. The engine switch 82 detects the presence or absence of the pressing operation (pressing operation) of the pressing operation unit 85 with the switch contact 86 housed in the case, and when detecting that the pressing operation unit 85 has been pressed, Each time an ON signal is output to the power supply ECU 83. When the engine switch 82 is pressed while the brake pedal is depressed, the power position is switched to the engine start state regardless of whether the power position is OFF, ACC on, or IG on. When the switch is pressed while the brake pedal is not depressed, the power supply position is repeatedly switched in the order of OFF → ACC → IG ON → OFF again every time the switch operation is performed.

When the power supply ECU 83 detects that the engine switch 82 is pressed while the engine 23 is in a stopped state and the brake pedal is depressed, the ACC relay, the IG relay, and the starter relay are all energized, and the engine Allow starting. On the other hand, when the power supply ECU 83 detects that the engine switch 82 is pressed when the engine is in operation when the vehicle is stopped, both the ACC relay and the IG relay are turned off to stop the engine. The power supply ECU 83 has various power supply functions in addition to the power supply transition function and the engine start / stop function. Examples of this function also include power supply to the battery charging system and power supply to the alternator control system. .
JP 2004-314806 A

  However, the engine start / stop switch device 81 disclosed in Patent Document 1 is composed of an engine switch 82 that is an operation part at the time of engine start / stop operation and a power supply ECU 83 that monitors the operation state of the switch 82. . For this reason, in the engine start / stop switch device 81 disclosed in Patent Document 1, both an arrangement space for the engine switch 82 and an arrangement space for the power supply ECU 83 are required. It was necessary to secure a wide arrangement space when mounting on the PC. However, since various on-vehicle products are mounted on the vehicle, effective use of the component arrangement space is an urgent problem in order to arrange a large number of these component groups, and the engine start / stop switch device 81 can be miniaturized as much as possible. There was a demand for effective use of the layout space.

  An object of the present invention is to provide a power switch device that can further reduce the size of the device.

  In order to solve the above problems, the present invention does not require the operation of inserting the key plate of the mechanical key into the key cylinder and turning it, and the power supply of the vehicle is subject to the condition that the key verification between the vehicle key and the vehicle is established. In a power switch device capable of switching states, a switch component which is operated when switching the power state of the vehicle and is manufactured as a single unit component, and each time the switch component is operated, A power control component capable of switching the state and switching the power state to at least one of the three states of the accessory on state, the ignition on state, and the engine start state during one operation from the off state; The gist of the present invention is that the power supply control component is integrated into the switch component.

  According to this configuration, since the power control component for controlling the power state of the power switch device is integrally incorporated in the switch component that is the operation location of the power switch device, such a switch component and the power control component are combined. The power switch device it has is made into one component. By the way, when integrating the power supply control component into the switch component, for example, if the power supply control component is incorporated in an empty space inside the switch component housing, the power supply control component is separated from the power supply control component. The device size of the switch device is reduced. Therefore, if the device structure in which the power control function is integrated in the switch part is taken, the device size of the power switch device can be reduced.

  In the present invention, the switch component has a mounting structure in which the electronic component of the switch component is mounted on a substrate, and the power control component is integrally incorporated by mounting the component group of the power control component on the substrate. It is a summary.

  According to this configuration, the electronic component of the switch component has a mounting structure that is mounted on the substrate, and the assembly destination when the power control component is incorporated into the switch component is the substrate. By the way, an electronic component of a switch component and a mounting destination of a power supply control component integrated into the switch component are substrates that are widely used today. Therefore, in this configuration, it is not necessary to use a special part as a mounting destination of various electronic parts, so that the structure of the power switch device can be simplified.

  In the present invention, the switch component has an attachment structure in which the electronic component of the switch component is directly mounted on the wiring, and the power control component is integrated by directly attaching the component group of the power control component to the wiring. The main point is that it is incorporated in

  According to this configuration, the electronic component of the switch component has a mounting structure that is mounted directly on the wiring, and the assembly destination when the power supply control component is assembled into the switch component is the wiring. By the way, when the mounting destination of the electronic component is only wiring, since this component has a wiring-only component structure, the component size is smaller than when a substrate is used, for example. For this reason, if the mounting destination of the electronic component of the switch component is the wiring itself, and the switch component is integrated into the power control component, the power control component is directly attached to the wiring. ), The power switch device can be further miniaturized.

  In the present invention, when the identification tag incorporated in the vehicle key receives the driving radio wave transmitted from the antenna installed in the vehicle, the identification tag starts activation and the identification code unique to the tag is An immobilizer system that transmits to a vehicle, and when the vehicle receives the identification code, collates the identification code, and permits or executes various vehicle operations when the collation is established, the switch component includes the immobilizer system The gist is that related parts are incorporated.

  According to this configuration, since a group of components related to the immobilizer system is incorporated in the switch component, it is possible to provide a power switch device having an immobilizer function.

The gist of the present invention is that the substrate or the wiring is provided with a switch contact for detecting the presence or absence of operation of the operation portion which is an operation location of the switch component.
According to this configuration, the switch contact that detects whether or not the operation part of the switch component is operated is also attached to the substrate or wiring on which various electronic components are mounted. Therefore, it is not necessary to prepare a separate board for the switch contact, so that it is possible to reduce the number of parts required for the power switch device.

  In the present invention, when mounted on a vehicle equipped with an electronic key system that performs key verification by wireless communication that transmits a key-specific identification code from an electronic key, and when switching the power state of the vehicle by operating the switch component, The gist is that the key verification according to the electronic key system is a condition.

  According to this configuration, the operation of switching the power state of the vehicle by the power switch device is conditional on the establishment of key verification by wireless communication according to the electronic key system. For this reason, since the power supply state switching operation cannot be performed unless the authorized electronic key is at hand, an unauthorized power supply state switching operation can be prevented.

  The gist of the present invention is that it comprises submergence detection means for detecting whether or not the electronic component of the switch part is submerged, and the submergence detection means uses the wiring as a detection location for submergence. .

  According to this configuration, even if the electronic component of the switch component is directly attached to the wiring, the exposed wiring is used as the detection location of the submergence detection means at this time. As in the case of using a substrate as a mounting destination, it is possible to detect the presence or absence of submersion without any problem.

  According to the present invention, the device size of the power switch device can be further reduced.

(First embodiment)
Hereinafter, a first embodiment of a power switch device embodying the present invention will be described with reference to FIGS.

  As shown in FIG. 1, the vehicle 1 is equipped with a hands-free system 2 that can perform door locking / unlocking and engine starting without actually operating a vehicle key. The hands-free system 2 transmits a request signal Srq from the vehicle 1 as an ID code reply request, and when the portable device 3 which is an electronic key receives the request signal Srq, the portable device 3 responds to the request by the portable device 3 with an ID unique to the key. When the ID signal Sid carrying the code (identification code) is automatically returned to the vehicle 1 and the ID code of the portable device 3 matches the ID code of the vehicle 1, various vehicle operations of the vehicle 1 (for example, door lock locking / unlocking and engine) The system is permitted or executed. The hands-free system 2 corresponds to an electronic key system, and the portable device 3 constitutes a vehicle key and an electronic key.

  The hands-free system 2 includes a smart entry system 4 that can be locked and unlocked without actually performing key operations. The smart entry system 4 will be described below. The vehicle 1 is provided with a verification ECU 5 that performs ID verification with the portable device 3. The verification ECU 5 includes an out-of-vehicle LF transmitter 6 that is embedded in a door or the like and can transmit an LF band signal outside the vehicle, and an in-vehicle LF transmitter 7 that is embedded under the floor of the vehicle and that can transmit an LF band signal into the vehicle. And an RF receiver 8 that is embedded in an in-vehicle rearview mirror or the like and can receive an RF band signal. These LF transmitters 6 and 7 can transmit the request signal Srq to the surroundings, and the outside LF transmitter 6 forms a communication area (external communication area) of the request signal Srq around the vehicle, and the in-vehicle LF transmitter 7 Forms a communication area (in-vehicle communication area) for the request signal Srq throughout the vehicle.

  For example, a touch sensor 9 embedded in a vehicle handle knob or the like is connected to the verification ECU 5. The touch sensor 9 detects an operation of touching the outside handle knob when the operator releases the locked door lock. For example, a lock button 10 provided on the outside handle knob is connected to the verification ECU 5. The lock button 10 is pushed when the operator locks the unlocked door lock. A door ECU 11 that controls the locking and unlocking of the door lock is connected to the verification ECU 5 through an in-vehicle LAN (Local Area Network) 12. The door ECU 11 drives the door lock motor 13 based on a command from the verification ECU 5 to place the door lock in a locked state or an unlocked state.

  The in-vehicle LAN 12 includes, for example, a LIN (Local Interconnect Network), a main CAN (Controller Area Network), a local CAN, and the like, and these are used alone or in combination. Here, LIN is a single-master in-vehicle LAN protocol, and is a network that has the advantage of lower cost than CAN. The main CAN is a multi-master in-vehicle LAN protocol, and is a network that has an advantage of a higher data transmission speed than the LIN. Furthermore, the local CAN is a network in which specific ECUs are connected by CAN communication and CAN communication is performed in a local environment.

  On the other hand, the portable device 3 includes a communication control unit 14 that functions as a control unit when performing wireless communication with the vehicle 1 according to the hands-free system 2, and an LF reception unit 15 that can receive an LF band signal. An RF transmitter 16 capable of transmitting an RF band signal is provided. The LF receiver 15 demodulates the LF band signal received by its own LF reception antenna 17 by the LF receiver circuit 18 and outputs the demodulated signal to the communication controller 14 as received data. Further, the RF transmitter 16 performs an operation of modulating the communication data obtained from the communication controller 14 by the RF transmitter circuit 19, and transmits an RF band ID signal Sid carrying a unique ID code of the portable device 3. A call can be made from the antenna 20.

  When the vehicle 1 is in a parked state (engine stopped and door lock locked), the verification ECU 5 intermittently transmits a request signal Srq for the LF band from the external LF transmitter 6 to form an external communication area around the vehicle. When the portable device 3 enters the outside communication area and receives the request signal Srq by the LF receiving unit 15, the portable device 3 responds to the request signal Srq, and the ID on which the ID code registered in its own memory 21 is placed. The signal Sid is returned from the RF transmitter 16 as an RF band signal. When the verification ECU 5 receives the ID signal Sid via the RF receiver 8, the verification ECU 5 compares the ID code registered in its own memory 22 with the ID code of the portable device 3 and performs ID verification (external vehicle verification). When the verification outside the vehicle is established, the verification ECU 5 recognizes the establishment of the verification outside the vehicle by setting an external verification establishment flag in the memory 22 and activates the touch sensor 9 that is on standby. When the touch sensor 9 detects a touch operation on the outside handle knob while the vehicle outside verification is established, the door ECU 11 rotates the door lock motor 13 to one side to release the locked door lock.

  On the other hand, when the vehicle 1 is in a stopped state (engine stop and door lock release state), the verification ECU 5 transmits a request signal Srq from the outside LF transmitter 6 when detecting that the lock button 10 is pressed. When the verification ECU 5 receives the request signal Srq and recognizes that the verification outside the vehicle is established in the ID signal Sid returned from the portable device 3, the verification ECU 5 outputs a door lock locking request to the door ECU 11. Receiving the door lock locking request, the door ECU 11 rotates the door lock motor 13 to the other side to lock the unlocked door lock.

  In the hands-free system 2, it is possible to start the engine 23 by simply operating the switch parts provided in the driver's seat in the vehicle without actually inserting the vehicle key into the key cylinder and turning it. There is a one push start system 24. The one-push start system 24 will be described below. This type of vehicle 1 is provided with an engine ECU 25 that performs ignition control and fuel injection control of the engine 23 in a state of being connected to the verification ECU 5 via the in-vehicle LAN 12. ing. The engine ECU 25 adjusts the vehicle speed by controlling the rotational speed of the engine 23 based on the amount of operation of the accelerator pedal 26 (see FIG. 2) by the driver. When the vehicle 1 is a hybrid vehicle, the engine ECU 25 at this time controls not only the rotational speed of the engine 23 but also the rotational speed of a motor (not shown) that acts as a vehicle drive source together with the engine 23.

  Further, the vehicle 1 is provided with a shift ECU 28 that controls the automatic transmission 27 of the vehicle 1 in a state of being connected to the in-vehicle LAN 12. A shift position detection sensor 30 that detects the range position of the shift lever 29 is connected to the shift ECU 28. The shift position detection sensor 30 includes, for example, a magnetic sensor or an optical sensor, and outputs a detection signal corresponding to the range position of the shift lever 29 to the shift ECU 28. The shift ECU 28 detects the range position of the shift lever 29 of the vehicle based on the detection signal acquired from the shift position detection sensor 30 so that the automatic transmission 27 takes the gear position corresponding to the range position. The automatic transmission 27 is controlled.

  As shown in FIG. 2, an engine start / stop switch device 32 is provided in the vicinity of the steering wheel 31 in the vehicle as an operation input system for switching the power supply state (power supply position) of the vehicle 1. The engine start / stop switch device 32 is provided with an engine switch 33 that forms the main body of the device. The engine switch 33 is composed of components that are unitized so that they can be handled as a single component, and is assembled to the vehicle 1 by attaching the unit components. The engine switch 33 is provided with a resin switch case 34 for storing various switch parts. In this example, the switch case 34 has, for example, a combination of a columnar shape and a box shape. The columnar portion serves as an operation component storage portion 34a that stores components of the operation portion system. The board component storage part 34b is stored. The engine start / stop switch device 32 corresponds to a power switch device, and the engine switch 33 corresponds to a switch component.

  In the operation component storage portion 34a of the switch case 34, a switch operation portion 35 that can be pressed (pushed) as an operation location of the engine switch 33 is provided in the longitudinal direction of the switch case 34 (operation component storage portion 34a) (see FIG. 2). It is attached so as to be capable of relative movement along the direction of arrow F1. The engine switch 33 is a momentary type that moves back when the switch operating unit 35 is pressed by the operator, and automatically returns to the original position when the hand is released from that state. Inside the switch case 34, a contact type switch contact 36 for detecting whether or not the switch operation unit 35 is operated is provided. The switch contact 36 outputs an ON signal when it detects that the switch operation unit 35 has been pressed, and outputs an OFF signal when the switch operation unit 35 is not operated. The switch operation unit 35 corresponds to the operation unit.

  In the engine switch 33, the switch operation unit 35 is pressed when switching the power state of the vehicle 1, and the power state of the vehicle 1 is changed to an OFF state (off state), an ACC on state (accessory on state), an IG on state ( It is possible to switch between four states: an ignition on state) and an E / G start state (engine start state). More specifically, when the engine switch 33 is pressed while the brake pedal 37 (see FIG. 2) is depressed while the engine is stopped, this will be in the E / G activated state regardless of the power position. Thus, the engine 23 is in an operating state. Further, when the engine 23 is in an operating state and the engine switch 33 is pressed while the vehicle 1 is in a stopped state, the power position of the vehicle 1 is turned off and the engine 23 is stopped. Further, when only the engine switch 33 is pressed without the brake pedal 37 being depressed when the shift lever 29 is positioned in the P range when the engine is stopped, the operation is performed every time the engine switch 33 is operated. The power position of the vehicle 1 is switched in the order of OFF state → ACC on state → IG on state.

  As shown in FIG. 1, the engine start / stop switch device 32 is provided with a switch ECU (switch Electronic Control Unit) 38 as a control unit. The switch ECU 38 includes various elements such as a CPU, a ROM, a RAM, a capacitor, and a coil (inductor), and is connected to the in-vehicle LAN 12 so as to perform data communication with the various ECUs. The switch ECU 38 is connected to a switch contact 36 for detecting whether or not the switch operation unit 35 is operated, and determines whether or not the switch operation unit 35 is operated based on a switch signal (ON signal, OFF signal) input from the switch contact 36. recognize.

  Further, the engine switch 33 incorporates a power control function for switching and controlling the power state (power position) of the vehicle 1 based on a switch signal from the switch contact 36. That is, in the engine start / stop switch device 32 of this example, the switch operation part and the power supply control function are integrated. The power control function of the present example includes an engine start / stop function that starts or stops the engine 23 when the engine switch 33 is operated, and the power state of the vehicle 1 is turned OFF every time the engine switch 33 is pressed. A power supply transition function that repeatedly switches in order from the on state to the IG on state is included. When the power control function is incorporated in the engine switch 33, the switch ECU 38, which is a control unit of the engine switch 33, is provided with a power control function circuit unit 39 that performs overall control of the power control function. The power control function circuit unit 39 is functionally generated by a CPU, a program, a capacitor, a coil, and the like, and this is expressed in a block diagram in FIG. The power control function circuit unit 39 corresponds to a power control component.

  When the switch ECU 38 has a power control function, an ACC relay 40 connected to the in-vehicle accessory, an IG relay 41 connected to the engine ECU 25, and a starter relay 42 connected to the starter are connected to the switch ECU 38. The switch ECU 38 controls the on / off switching of the relays 40 to 42 based on the operation of the engine switch 33 (switch operation unit 35). A brake sensor 43 that detects whether or not the brake pedal 37 is operated is connected to the switch ECU 38 via the in-vehicle LAN 12. The switch ECU 38 recognizes whether or not the brake pedal 37 is operated based on a detection signal acquired from the brake sensor 43. A vehicle speed sensor 44 that detects the vehicle speed of the vehicle 1 is connected to the switch ECU 38 via the in-vehicle LAN 12. The switch ECU 38 confirms the vehicle speed based on the detection signal acquired from the vehicle speed sensor 44.

  When the collation ECU 5 detects that the door is opened, for example, from a courtesy switch or the like (not shown) after the outside collation is established and the door lock is released, the collation ECU 5 recognizes that the driver gets on and recognizes the in-vehicle LF transmitter 7. Transmits a request signal Srq to form an in-vehicle communication area. When the RF signal is received by the RF receiver 8, the verification ECU 5 compares the ID code registered in the mobile device 3 with the ID code of the mobile device 3. Perform (in-vehicle verification). When the in-vehicle verification is established, the verification ECU 5 sets an in-vehicle verification establishment flag in the internal memory and recognizes that the in-vehicle verification is established.

  When the power supply control function circuit unit 39 detects that the engine switch 33 is pressed while the engine 23 is stopped and the brake pedal 37 is depressed while the in-vehicle collation is established, the ACC The relay 40, the IG relay 41 and the starter relay 42 are all turned on, and the power position of the vehicle 1 is switched to the E / G activation state regardless of whether the power position of the vehicle 1 is OFF, ACC on or IG on. The engine 23 is started. On the other hand, when the power supply control function circuit unit 39 detects that the engine switch 33 is pressed while the vehicle 1 is stopped while the engine 23 is in operation, both the ACC relay 40 and the IG relay 41 are turned off, thereby 1 is turned off and the engine 23 is stopped.

  Further, the power control function circuit unit 39 does not operate the brake pedal 37 when the engine 23 is stopped and the shift lever 29 is positioned in the P range when the in-vehicle verification is established. If only the engine switch 33 is pressed, the power position of the vehicle 1 is repeatedly switched in the order of OFF state → ACC on state → IG on state every time the engine switch 33 is pressed. For example, when the engine switch 33 is pressed once when the power position of the vehicle 1 is in the OFF state under the above-described situation, the power position is switched to the ACC on state, and from this state, the engine switch 33 is further turned on. When the pressing operation is performed once, the power supply position is switched to the IG ON state, and when the pressing operation is performed once more, the power supply position is switched to the OFF state again.

  The vehicle 1 is equipped with an immobilizer system 46 that performs ID verification (immobilizer verification) using a transponder 45 embedded in the portable device 3. This immobilizer collation is a collation system different from the above-described ID collation (external vehicle collation and in-car collation) which is performed by returning the ID signal Sid to the vehicle 1 when the portable device 3 receives the request signal Srq. By mounting the immobilizer system 46 on the vehicle 1, it is possible to implement a plurality of verification systems to further prevent unauthorized use of the vehicle 1, and to perform ID verification by wireless communication even if the battery of the portable device 3 runs out Satisfies the measures for running out of batteries.

  When the immobilizer system 46 is mounted on the vehicle 1, a transponder key coil 47 that works as a vehicle-side antenna of the immobilizer system 46 is assembled at the tip of the switch case 34. A plurality of transponder key coils 47 are wound around the switch operation unit 35 in a ring shape, and are attached as an integral part, for example, by molding or the like inside the switch case 34 (operation component storage unit 34a). The transponder key coil 47 has a pair of ends connected to the switch ECU 38 and can transmit a driving radio wave Svu that can activate the transponder 45 only to the periphery of the engine switch 33. The transponder 45 corresponds to an identification tag, and the transponder key coil 47 corresponds to an antenna.

  The switch ECU 38 is provided with an immobilizer control unit 48 that performs overall control of the immobilizer system 46. The immobilizer control unit 48 transmits a driving radio wave Svu that can activate the transponder 45 embedded in the portable device 3 from the transponder key coil 47 and confirms data contents of various reception signals received by the transponder key coil 47. Immobilizer verification is performed by bringing the portable device 3 close to the transponder key coil 47 to activate the transponder 45 with the driving radio wave Svu transmitted from the transponder key coil 47, and the transponder code signal Str sent back by the activated transponder 45 is returned. It is ID collation which collates the code number in the vehicle 1 side.

  When the verification ECU 5 detects that the driver pushes the engine switch 33 while depressing the brake pedal 37, the verification ECU 5 performs an operation of confirming whether or not the in-vehicle verification is established as an authentication operation before the engine start. The target for verification is not limited to ID verification according to the hands-free system 2. That is, the verification ECU 5 performs at least confirmation of ID verification according to the hands-free system 2 and ID verification according to the immobilizer system 46 at the time of confirmation of ID verification establishment in the wireless communication environment with the portable device 3. If either of them is established, it is recognized that the in-vehicle verification is established.

  As shown in FIG. 4, a switch support portion 55 that supports the switch operation portion 35 from the back surface side is integrally provided on the back surface of the switch operation portion 35. The switch support portion 55 is housed in the operation component housing portion 34a of the engine switch 33, and moves synchronously when the switch operation portion 35 is pressed or released. Further, the operation component storage portion 34a of the engine switch 33 stores an elastic member 56 that urges the switch operation portion 35 and the switch support portion 55 in the counter-pressing direction of the switch operation portion 35 (the direction of arrow F2 in FIG. 4). ing. The elastic member 56 is a component that causes the engine switch 33 to function as a momentary switch, and includes, for example, a coil spring. One end of the elastic member 56 is attached and fixed to the switch support portion 55, and the other end is attached and fixed to the inner surface of the operation component storage portion 34a.

  A movable contact 51 b of the switch contact 36 is provided on the back surface of the switch operation unit 35. Therefore, when the switch operation unit 35 is pressed, the movable contact 51b comes into contact with the fixed contact 51a, and the switch contact 36 is turned on. On the other hand, when the switch operating unit 35 is pressed and then released, the elastic member 56 is used to move the switch operating unit 35 in the reverse pressing direction and return to the original state. At this time, the movable contact 51b is a fixed contact. The switch contact 36 is turned off at a distance from 51a.

  As shown in FIG. 3, a submergence detection sensor 57 that detects whether or not the engine switch 33 is submerged is provided at the edge position of the substrate 50. The submergence detection sensor 57 has a pair of submergence detection terminals 57a and 57b provided at the two opposite edges of the four sides of the substrate 50, which are made of, for example, a small metal plate. In the submergence detection sensor 57, as shown in a circuit diagram in FIG. 6, an intermediate terminal 58 between the submergence detection terminals 57 a and 57 b is connected to the switch ECU 38 via a transistor 59 that is also formed on the substrate 50. . The transistor 59 has a collector terminal connected to a power source, an emitter terminal connected to the switch ECU 38, and a base terminal connected to an intermediate terminal 58 of the submergence detection terminals 57a and 57b.

  For example, assuming that the engine switch 33, that is, the substrate 50 is submerged, a leak resistance is generated in the sensor circuit of the submergence detection sensor 57. Therefore, the terminal voltage of the intermediate terminal 58 of the submergence detection terminals 57a and 57b. (Bridge voltage) changes, and the operation state of the transistor 59 is switched. Since the switch ECU 38 constantly monitors the operation state of the transistor 59, the switch ECU 38 determines whether or not the engine switch 33 is submerged by observing this state. When the switch ECU 38 recognizes that the engine switch 33 has been submerged, for example, the power switch is forcibly shut down and the operation of the engine switch 33 is forcibly terminated.

Next, the operation of the engine switch 33 configured as described above will be described.
First, while the vehicle 1 is stopped and the engine 23 is in a stopped state, the engine switch 33 is pressed in a state where the shift lever 29 is positioned in the P range and the brake pedal 37 is depressed. Suppose. At this time, the power supply control function circuit unit 39 inputs an ON signal from the switch contact 36 of the engine switch 33. When the ON signal is input from the switch contact 36, the verification ECU 5 first checks the in-vehicle verification result. The verification ECU 5 that has received the confirmation request for the in-vehicle verification result from the power control function circuit unit 39 notifies the power control function circuit unit 39 that the in-vehicle verification has been established if the in-vehicle verification has already been established. Output.

  On the other hand, if the in-vehicle collation is not established at this time, the collation ECU 5 transmits the request signal Srq again from the in-vehicle LF transmitter 7 to form an in-vehicle communication area and tries to establish the in-vehicle collation again. . When the verification ECU 5 recognizes that the in-vehicle verification is not established even under this situation, the verification ECU 5 outputs a notification that the in-vehicle verification is not established to the power control function circuit unit 39. When the power supply control function circuit unit 39 receives notification from the verification ECU 5 that the in-vehicle verification is not established, the operation of the engine switch 33 at this time is ignored, and the engine start operation by the engine switch 33 is not permitted.

  When receiving a notification that the in-vehicle verification has been established from the verification ECU 5, the power control function circuit unit 39 checks whether or not the brake pedal 37 has been depressed. When the power supply control function circuit unit 39 inputs an ON signal as a notification that the brake pedal 37 is operated from the brake sensor 43, the power supply control function circuit unit 39 turns on the ACC relay 40, the IG relay 41, and the starter relay 42 that have been in the OFF state. Then, the power supply position of the vehicle 1 is set to the E / G activation state, and an activation signal is output to the engine ECU 25. That is, when the engine switch 33 is pressed while the brake pedal 37 is depressed while the engine 23 is stopped, the engine 23 is put into an operating state.

  The engine ECU 25 that has received the start-up signal uses the encrypted communication to confirm the in-vehicle collation result with the collation ECU 5 and pairing that confirms whether or not the collation ECU 5 of the communication destination is a pair. Do. When the engine ECU 25 recognizes that the above-described two verifications of the in-vehicle verification result and the pairing described above have been normally completed with the verification ECU 5, the engine ECU 25 performs ignition control and fuel injection to the engine 23 while turning the starter motor. Control is started and the engine 23 in a stopped state is put into an operating state. As described above, the engine 23 is in an operating state by the pressing operation of the engine switch 33.

  Further, it is assumed that the engine switch 33 is pressed while the vehicle 1 is stopped while the engine 23 is operating. At this time, the power control function circuit unit 39 receives an ON signal from the switch contact 36 of the engine switch 33. At this time, the engine 23 is in an operating state, but the vehicle 1 stops at a vehicle speed of “0”. If it confirms that it is in a state, both the ACC relay 40 and the IG relay 41 that have been on until then are turned off, and the power position of the vehicle 1 is switched to the off state. As a result, the engine 23 that has been operating until then is stopped.

  On the other hand, it is assumed that only the engine switch 33 is pressed while the vehicle 1 is stopped and the engine 23 is in a stopped state and the brake pedal 37 is not depressed in that state. At this time, the power supply control function circuit unit 39 receives an ON signal from the switch contact 36, but first checks the in-vehicle verification result with the verification ECU 5, as in the case of the engine start operation. The verification ECU 5 that has received the confirmation request for the in-vehicle verification result from the power control function circuit unit 39 outputs a notification that the in-vehicle verification has been established to the power control function circuit unit 39 if the in-vehicle verification has already been established. If the in-vehicle verification is not established, the in-vehicle verification is performed again to check whether the in-vehicle verification is established.

  When receiving a notification that the in-vehicle verification has been established from the verification ECU 5, the power control function circuit unit 39 checks whether or not the brake pedal 37 has been depressed. When the power supply control function circuit unit 39 inputs an off signal as a notification that the brake pedal 37 is not operated from the brake sensor 43, the power control function circuit unit 39 then confirms the operation position of the shift lever 29 at that time to the shift ECU 28, and the shift lever 29 is in the P range. If it is a position, power supply transition control is performed. That is, when the vehicle 1 is stopped, the engine 23 is stopped, and the shift lever 29 is positioned in the P range, the power control function circuit unit 39 does not depress the brake pedal 37 and operates the engine switch 33. When only the pressing operation is detected, the power position of the vehicle 1 is repeatedly switched in the order of OFF state → ACC on state → IG on state every time the engine switch 33 is operated.

  For example, when the vehicle 1 is in a stopped state and the power position at that time is in an OFF state, if only the engine switch 33 is pressed once without the brake pedal 37 being depressed, the power control function circuit unit 39 is The ACC relay 40 is turned on, and the power supply position is turned on. In this state, when the brake pedal 37 is not depressed and only the engine switch 33 is pressed once more, the power control function circuit unit 39 is switched to the IG relay instead of the ACC relay 40 that has been in the on state. 41 is turned on, and the power supply position is turned on. If the engine switch 33 is pressed once again without the brake pedal 37 being depressed from this state, the power supply control function circuit unit 39 turns off the IG relay 41 that has been on until then. Thus, all the relays 40 to 42 are turned off, and the power supply position is turned off again. The power supply control function circuit unit 39 performs power supply transition control by switching the power supply position of the vehicle 1 as described above.

  By the way, for example, assuming that the power supply control function is configured separately from the engine switch 33 in the engine start / stop switch device 32, the component parts of the engine start / stop switch device 32 at this time are the engine start / stop switch device 32. It takes the form of an apparatus consisting of an engine switch that is the actual operation location during the stop operation and a power supply control unit (so-called power supply ECU) that performs overall control of the power supply control function. Therefore, in the case of this apparatus form, Since the engine start / stop switch device 32 is composed of two parts, there is a concern that the size of the device increases accordingly. When the device size is increased in this way, when the engine start / stop switch device 32 is mounted on the vehicle, a wider arrangement space is required. Therefore, there is a problem that the arrangement position is restricted in some cases, such as being unable to arrange in a desired place. Conceivable.

  Therefore, in this example, since there is an empty space inside the switch case 34 of the engine switch 33, an apparatus configuration in which the power supply control function is integrated into the engine switch 33 using this empty space is adopted. did. As a result, the engine start / stop switch device 32 can have only one component, and the engine start / stop switch device 32 can be reduced in size accordingly. Therefore, when the engine start / stop switch device 32 is mounted on the vehicle, the engine start / stop switch device 32 can be placed at a place where the placement space is limited, and the degree of freedom of the placement of the engine start / stop switch device 32 is increased. Further, when the engine start / stop switch device 32 is assembled to the vehicle body, the number of steps required for the assembly is reduced, and the assembling work can be simplified accordingly.

According to the configuration of the present embodiment, the following effects can be obtained.
(1) Since the power control function (power control function circuit unit 39) is integrated into the engine switch 33, the engine start / stop switch device 32 having such an engine system switch component and a power control function can be integrated into one component. Figured. For this reason, for example, if a component group of the power control function is incorporated in an empty space in the switch case 34 of the engine switch 33, the device size of the engine start / stop switch device 32 is smaller than when these two components are separate. In this example, the engine start / stop switch device 32 can be downsized.

  (2) The printed circuit board 50 is accommodated in the switch case 34, and various electronic components 49 of the engine start / stop switch device 32 are mounted on the board 50. Therefore, in this example, the mounting destination of the various electronic components 49 is the board (printed wiring board) 50 that is widely used today. For this reason, since it is not necessary to use a special component as a mounting destination of the various electronic components 49, the structure of the engine start / stop switch device 32 can be simplified. Further, when this type of board 50 increases the number of wirings, it can be handled simply by increasing the number of printed wirings in the board manufacturing process. For example, the number of electronic components 49 of the engine start / stop switch device 32 is assumed to be small. Even if the number increases, the electronic component 49 can be attached without much trouble.

  (3) Since the immobilizer system 46 is incorporated in the engine switch 33, the engine start / stop switch device 32 having this kind of immobilizer function can be provided. Therefore, if the engine start / stop switch device 32 is assembled to the vehicle body, the immobilizer system 46 is assembled to the vehicle body at the same time during the assembly operation, so that the operation at the time of component assembly can be simplified.

  (4) On the board 50 on which various electronic components 49 of the engine start / stop switch device 32 are mounted, a switch contact 36 for detecting whether or not the switch operation unit 35 is operated is also mounted. Therefore, it is not necessary to separately prepare a board dedicated for this type of switch contact, so that the number of parts required for the engine start / stop switch device 32 can be reduced.

  (5) The switching operation of the power state of the vehicle 1 by the engine switch 33 is subject to the establishment of ID verification (in-vehicle verification) by wireless communication in accordance with the hands-free system 2. For this reason, since the switch operator cannot switch the power supply state unless he / she has the authorized portable device 3 at hand, the switch operation of the power supply state can be prevented.

  (6) Since the power control function (power control function circuit unit 39) is integrally assembled with the engine switch 33, the engine switch parts described in the background art and the power control function are necessary when they are separated. The harness to connect can be made unnecessary. Therefore, if the harness can be omitted in this way, the material cost required for the harness can be reduced, and further, the work process of connecting the harness can be eliminated.

(Second Embodiment)
Next, 2nd Embodiment of this example is described according to FIGS. Since the second embodiment has a configuration in which the mounting destination of various electronic components of the engine switch 33 is changed, the same parts as those in the first embodiment are denoted by the same reference numerals, detailed description thereof is omitted, and is different. Only the part will be described in detail.

  As shown in FIG. 6, a plurality of wires 61, 61... Are installed in the switch case 34 as attachment destinations of various electronic components 49 of the engine start / stop switch device 32 instead of the substrate 50 described in the first embodiment. Is stored. That is, in the second embodiment, the electronic component 49 is not mounted on the substrate 50 as in the first embodiment, but has an attachment structure in which the electronic component 49 is directly attached to the exposed wires 61, 61. ing. The wirings 61, 61... Are made of a metal such as copper and have an elongated plate shape. The electronic component 49 of the engine start / stop switch device 32, that is, various components of the switch ECU 38 (power control function circuit unit 39, immobilizer control unit 48, etc.) and the fixed contact 51a of the switch contact 36 are connected to the wires 61, 61. It is attached so as to straddle these.

  As shown in FIGS. 6 to 8, these wirings 61, 61... Are composed of straight wirings that extend straight and bent wirings that are bent into, for example, a U shape. Further, these wirings 61, 61... Are in a three-dimensional arrangement state that overlaps with a distance in the vertical and horizontal directions. The ends of these wirings 61, 61... Are supported by the connector 52, and portions protruding from the connector 52 to the outside are used as pins of the connector 52. Further, the wirings 61, 61... Are housed inside the switch case 34 in a state where they are supported inside the board component housing portion 34b of the switch case 34. Further, the widths of these wirings 61, 61... Are set according to the magnitude of the flowing current. That is, among the wirings 61, 61..., The one with a high flowing current is formed with a large width, and the one with a low flowing current is formed with a narrow width.

  In this example, since the various electronic components 49 of the engine start / stop switch device 32 are directly attached to the wirings 61, 61..., The small electronic components 49 are attached only to the wirings 61, 61. It will be of size. For this reason, it is possible to reduce the size of the engine start / stop switch device 32, that is, the engine switch 33 accordingly. If the wirings 61, 61,... Are arranged three-dimensionally as in this example, the wirings 61, 61,... The size is very small. For this reason, along with the downsizing of the components of the wires 61, 61..., The engine start / stop switch device 32, that is, the engine switch 33 can be further reduced in size.

  Further, these wirings 61, 61... May have a storage structure in which resin is sealed in the switch case 34 by pouring resin into the switch case 34 and then curing the resin after being stored in the switch case 34. . When the storage structure in which the wirings 61, 61,... Are sealed with resin in the switch case 34, the wirings 61, 61,. Is added, it is difficult for the situation to bend to occur, and the resistance of the wirings 61, 61... Can be increased.

  Further, even when an attachment structure in which various electronic components 49 of the engine start / stop switch device 32 are directly attached to the wirings 61, 61,..., A submergence detection sensor 57 similar to that of the first embodiment may be provided. In this case, as shown in FIG. 9, two predetermined wirings 61a and 61b are connected by a submergence detection wiring 61c, and the voltage on the path of the wiring 61c is applied to the transistor 59 as a bridge voltage. If this structure is adopted, even if the mounting structure for directly attaching the electronic components of the engine switch 33 to the wirings 61, 61... Is adopted, the mounting structure for mounting the various electronic components 49 described in the first embodiment to the board 50. Similarly to the time, it is possible to detect whether or not the engine start / stop switch device 32 (substrate 50) is submerged. The wiring 61c constitutes a submergence detection unit.

According to the configuration of the present embodiment, in addition to the effects described in (1) and (3) to (6) of the first embodiment, the following effects can be obtained.
(7) As the mounting structure of the electronic component 49 of the engine start / stop switch device 32, a mounting structure in which various electronic components 49 are directly mounted on the wirings 61, 61. By the way, when the mounting destination of the electronic component 49 is composed of only the wirings 61, 61..., This component has a component structure composed only of the wirings 61, 61. Therefore, if the various electronic components 49 of the engine start / stop switch device 32 are directly attached to the wirings 61, 61..., The engine start / stop switch device is reduced as the component size of the mounting destination component is reduced. 32 can be further reduced in size.

  (8) Even if the electronic component 49 of the engine start / stop switch device 32 is directly attached to the wiring 61, the exposed wiring 61 is used as a submerged sensor at this time. As in the case where the substrate 50 is used as the mounting destination of the electronic component 49, it is possible to detect the presence or absence of submersion without any problem.

Note that the embodiment is not limited to the configuration described so far, and may be modified as follows.
In the first and second embodiments, the power control function integrated into the engine switch 33 is not necessarily limited to the engine start / stop function and the power transition function.

It is not limited to the one that can be switched to the E / G activation state. In other words, the power supply state may be changed to at least one of the three states of the ACC on state, the IG on state, and the E / G start state while the operation of the engine switch 33 is completed once from the off state. . At this time, if the engine start system is not included in the power control function, the engine may be started with a mechanical key.

  In the first and second embodiments, the engine switch 33 is not necessarily limited to a pressing type in which the switch operation unit 35 is pressed (push operation). For example, the switch operation unit 35 is formed in a knob shape, and this knob is turned. A rotary operation type (knob operation type) for switching the power supply state may be used. In this case, a slot in which the portable device 3 can be inserted into the knob is formed, and when the portable device 3 is inserted into this slot, the switch ECU 38 that has been in a standby state is activated to switch the power supply state. May be adopted.

  In the first and second embodiments, the mounting destination of the various electronic components 49 of the engine start / stop switch device 32 is not necessarily limited to one of the substrate 50 and the wiring 61, and the substrate 50 and the exposed wiring 61 in the switch housing. When both are present, both the substrate 50 and the wiring 61 may be the mounting destination.

In the first and second embodiments, the engine start / stop switch device 32 does not necessarily have an immobilizer function and may be omitted.
In the first and second embodiments, the switch contact 36 is not necessarily formed on the same substrate as the power supply control function circuit unit 39 and the immobilizer control unit 48, and is formed in another place independent of these. May be.

In the first and second embodiments, the portable device 3 may be provided with a lock button or an unlock button, and the portable device 3 may be provided with a wireless function.
In the first and second embodiments, the switch contact 36 is not necessarily limited to a contact type, and may be a contactless type using a magnetic sensor or an optical sensor, for example.

  In the first and second embodiments, the smart entry system 4 always detects the operation of the lock button 10 by unlocking the door lock that has been locked until the handle knob operation is detected by the touch sensor 9. However, the structure is not limited to the structure that locks the door lock that has been unlocked until then. For example, when the door lock of the vehicle 1 is locked, if the user who owns the portable device 3 approaches the vehicle 1, the door lock is automatically unlocked, and when the door lock is unlocked, the portable device 3 is owned. A structure in which the door lock is automatically locked when the user leaves the vehicle 1 may be employed.
