[0001]
BACKGROUND OF THE INVENTION
The present invention relates to a remote control device used for a keyless entry device of a vehicle, and in particular, it is possible to easily analyze a failure content (for example, analysis of whether the transmitter side is a failure or the receiver side is a failure). The present invention relates to a remote control device.
[0002]
[Prior art]
For example, in a keyless entry device for a vehicle that has been widely used in recent years, a predetermined control target (for example, a locking device for a vehicle door) is used as a portable transmitter (for example, a device integrated with a vehicle key). A remote control device for remotely operating with a radio signal using a receiver installed on a control target side (for example, a vehicle side) is used. And in such a remote control device that requires crime prevention, a signal including at least a key code (or a unique code called an ID code) is wirelessly transmitted from a transmitter, and a receiver that receives this signal, On the condition that the key code included in the received signal corresponds to the key code set in the receiver in advance, a predetermined output for controlling a predetermined control target (for example, unlocking or locking) Control signal output).
In some cases, the transmitter is provided with a plurality of switches for signal transmission, and a function code corresponding to these switches is transmitted as a part of the contents of the wireless signal to improve operability and increase the functionality. Is planned. For example, in a vehicle keyless entry device, an unlocking switch and a locking switch are separately provided in a transmitter, and when the unlocking switch is operated, a signal including a function code for unlocking is transmitted, The receiver that has received this reads the function code and outputs the unlocking control signal without fail.On the other hand, when the locking switch is operated, it sends a signal containing the function code for locking, There is a case where the receiving receiver reads the function code and reliably outputs a lock control signal. In addition to the unlocking switch and the locking switch, a separate switch for sending a function code for commanding opening and closing of the trunk, opening and closing of the window, starting of the engine, operation of the horn and the like is further provided. These operations may also be configured to be remotely operated with a radio signal from a transmitter.
[0003]
[Problems to be solved by the invention]
By the way, in the above-mentioned conventional remote control device, all the remote operations are impossible unless the verification of the unique key code for each device matches, and the function of notifying whether the signal transmission / reception itself and its contents are normal or not is provided. Because there was no failure, it was a problem that it was not possible to easily analyze the content and cause of the failure when a failure occurred such that the remote control could not be performed despite operating the transmitter switch. . In other words, in order to repair the above-mentioned failure at a minimum cost, whether the transmitter side fails and remote operation is not possible, whether the receiver side or control target side fails and remote operation is not possible, or the data content of the signal It is necessary to obtain information such as whether or not the discrimination and collation at the receiver side are normal. However, in the past, such information could not be obtained easily, so that both the receiver and the transmitter were exchanged even though the receiver side was out of order. Even though the settings are poor, the device itself may be replaced, which may require unnecessary repair costs. This is because, in the past, for example, it was impossible to check the individual operation of the receiver of a faulty device using a transmitter of another device of the same specification (because the key code is different, the device Does not work even if it is normal), a dedicated operation confirmation device (for example, a transmitter that can transmit signals including various key codes, or a receiver that reads and displays data of transmitted radio signals regardless of the key code). It is necessary separately, and it is necessary to specially hold such special inspection equipment at the dealer of the vehicle, etc., or in some cases it is necessary to remove the receiver from the vehicle etc. for individual operation confirmation This is because the operation check operation for obtaining the above-described information has become troublesome requiring equipment and labor.
Therefore, an object of the present invention is to provide a remote control device that can easily analyze a failure content (for example, an analysis of whether the transmitter side is a failure or the receiver side is a failure).
[0004]
[Means for Solving the Problems]
In order to achieve the above object, a remote control device according to claim 1 receives a transmitter wirelessly transmitting a signal of a predetermined specification including at least a key code, and receives the signal wirelessly transmitted from the transmitter, In a remote control device including a receiver that performs a predetermined output on condition that the key code included in the received signal corresponds to the set key code,
When the receiver receives a signal having the same specification as the signal transmitted from the transmitter, the receiver performs notification even if the key code included in the received signal is different from the set key code.Configuration
The notification by the notification means includes one that notifies the contents of the data included in the received signal in a distinguishable manner.It is characterized by that.
The “data content included in the received signal” means the code data itself included in the received signal, and is, for example, an enumeration of “1” and “0” or a hexadecimal number.
[0005]
Further, in the remote control device according to claim 2, in addition to the key code, the signal includes a function code for instructing the type or content of the predetermined output,For notification by the notification means,Depending on the type of the function code included in the received signal, different types or aspectsIncludes notifications to doIt is characterized by that.
Also billed3The remote control device described in the item is characterized in that the notification by the notification unit is performed only in a state where a specific operation mode different from a normal operation mode of the receiver is set.
[0006]
DETAILED DESCRIPTION OF THE INVENTION
Hereinafter, an example of an embodiment of the present invention will be described with reference to the drawings.
FIG. 1 is a diagram showing an example of a remote control device in a keyless entry device of a vehicle, FIG. 2 is a flowchart showing characteristic processing contents of the receiver of this example, and FIG. 3 is a radio transmitted and received in this example It is a figure which shows the outline of the content of a signal.
As shown in FIG. 1, this remote control device includes a transmitter 10 and a receiver 20. In this case, the transmitter 10 has a locking switch 11 and an unlocking switch 12 for locking or unlocking the entrance door of the vehicle on the surface, and either of these switches 11 or 12 is pressed. When this is done, a radio signal including a function code corresponding to the switch is output as, for example, an electromagnetic wave (including at least radio waves and infrared rays in a narrow sense), and the internal configuration is not shown. The radio signal transmitted from the transmitter 10 is a serial transmission method signal in which a digital signal (pulse signal) of “1” or “0” is converted into an analog signal of an electromagnetic wave and transmitted in time series, As shown in FIG. 3, there are six data frames (a group of signals) having the same contents in time series. In other words, when the switch 11 or 12 is operated once, a signal composed of one data frame is sequentially transmitted six times sequentially.
[0007]
In this case, as shown in FIG. 3, the data of the synchronization code, custom code, ID code, rolling code, function code, and stop bit (ST) are included in one data frame in time series. Among them, the synchronization code is code data composed of a plurality of bits functioning as so-called start bits. When this code data set in advance on the receiver side is read, the receiver side reads the head of one data frame. (That is, the data received next is determined to be data of a custom code in this case). The custom code is code data set on the vehicle manufacturer side, and data corresponding to the vehicle type, grade, etc. is normally set. The ID code is a so-called key code, and unique code data is set for each apparatus in order to have a function as a key. In addition, the rolling code is used to prevent the vehicle from being stolen by illegally creating a transmitter capable of transmitting the same type of signal including the same key code by duplicating the transmitted signal. Code data, each time a radio signal is transmitted from the transmitter, the value is incremented (increased) by “1” by the processing of the control circuit of the transmitter. The receiver side stores the value of the last received rolling code. When a radio signal is received, the rolling code value of the received signal is compared with the latest stored value to roll the received signal. The command of the received signal is treated as valid only when the code value is larger and the difference is within a certain range. The function code is code data set in accordance with the content of the remote operation (operated switch) as described above. The stop bit (ST) is 1-bit data for notifying the receiver that it is the end of one data frame, and is set to “0”, for example.
[0008]
On the other hand, as shown in FIG. 3, the receiver 20 includes a microcomputer 21 including a CPU, a ROM and a RAM (hereinafter referred to as a microcomputer 21), a power supply circuit 22, an input circuit 23, a receiving circuit 24, and an E²A PROM 25, an output circuit 26, an oscillation circuit 27, connectors 28 and 29 for external input / output connection, and a crystal oscillation buzzer 30 are provided. Here, the power supply circuit 22 is a circuit that converts the output of the battery 31 of the vehicle and supplies stable power of a predetermined voltage to the microcomputer 21. The input circuit 23 and the output circuit 26 are circuits for inputting / outputting signals of the microcomputer 21. The receiving circuit 24 receives an electromagnetic wave signal transmitted from the transmitter 10 via the antenna 24a, performs a predetermined demodulation process (a process of converting an electromagnetic wave analog signal into a digital signal), and the like, and the microcomputer 21. Is a circuit that outputs the signal. E²The PROM 25 is an electrically erasable and writable non-volatile memory. In this case, data such as the aforementioned custom code and ID code (key code) are registered in this memory. The operation program of the microcomputer 21 and some other data are registered in the ROM in the microcomputer 21. The oscillation circuit 27 is a circuit that generates a pulse that is a source of an operation clock of the microcomputer 21.
The output circuit 26 has a buzzer 30 and a lamp 32 (a lamp existing in the vehicle; for example, a headlamp or a brake lamp) installed at any location (a location where the vehicle can be seen). The buzzer 30 and the lamp 32 are configured to operate under the control of the microcomputer 21. In this case, the buzzer 30 and the lamp 32 and the microcomputer 21 constitute the notification means of the present invention.
[0009]
Next, characteristic operations of the receiver 20 (characteristic control processing of the microcomputer 21) will be described with reference to the flowchart of FIG. When the microcomputer 21 is powered on and activated, the microcomputer 21 repeatedly executes the following series of processes in a predetermined cycle.
First, in step S1, it is determined whether or not the inspection mode is set. If it is set, the process proceeds to step S2, and if it is not set (that is, in the normal operation mode), the process branches to step S12. Execute normal operation processing. The inspection mode is a specific operation mode that is different from the normal operation mode of the receiver 20, and an operation of, for example, a mechanical switch (not shown) provided on the vehicle so that it is difficult for the user of the normal vehicle to operate. Therefore, the microcomputer 21 can be set. The normal operation process is a process of normal operation performed in a separate routine (not shown in detail) in this case, and is a process of performing control output corresponding to the function code when an appropriate radio signal is received. . Specifically, for example, when an appropriate signal (including a function code for locking) transmitted by pressing the locking switch 11 of the transmitter 10 is received via the receiving circuit 24, the illustration is omitted. This is a process of sending a control signal to the actuator of the vehicle door locking device and operating the actuator on the locking side.
[0010]
In step S2, it is determined whether or not the pulse width of the signal received via the receiving circuit 24 is appropriate. If appropriate, the process proceeds to step S3, and if not appropriate, the process of one cycle is terminated. Here, “appropriate pulse width” means that the time width of the pulse signal representing “1” or “0” matches the time width set in advance in the ROM or the like of the microcomputer 21 within an allowable error range. . The pulse width may be set to different values (for example, 1 msec and 2 msec) separately for “1” and “0” in order to improve communication reliability.
Next, in step S3, the contents of the currently received signal ("1" or "0" data string) are sequentially read, and if there is a part that matches the synchronization code registered in advance in the ROM or the like in the microcomputer 21, Proceed to the next Step S4. If the portion matching the synchronization code cannot be read, the process of sequentially reading the signals is continued. However, if a portion that coincides with the synchronization code cannot be read even after a certain period of time has elapsed, one cycle of processing may be terminated.
[0011]
In step S4, the signal from the synchronization code to the bit determined to be the stop bit is read and temporarily stored, and the total number of bits from the synchronization code to the stop bit is counted and registered in advance in a ROM or the like in the microcomputer 21. Compare with the total number of bits of one data frame, and if they match, the process proceeds to the next step S5. If the total number of bits does not match, the process returns to step S3.
Next, in step S5, a data string having a predetermined number of bits subsequent to the synchronization code in the signal read in step S4 is E.²It is determined whether or not it matches the data string of the custom code registered in advance in the PROM 25. If they match, the process proceeds to step S6, and if they do not match, the process of one cycle is terminated.
Next, in step S6, a data string having a predetermined number of bits following the portion determined as the custom code in step S5 in the signal read in step S4 is received as a predetermined ID such as RAM in the microcomputer 21 as received ID code data. The data is stored (stored) in the address, and the subsequent data string having a predetermined number of bits is similarly stored as the data of the received rolling code.
[0012]
Next, in step S7, a data string of a predetermined number of bits subsequent to the portion stored as the rolling code in step S6 in the signal read in step S4 is a function code data (registered in advance in a ROM or the like in the microcomputer 21). If there is a plurality, it is determined whether or not it matches, and if it matches, the process proceeds to step S8, and if it does not match, the process of one cycle is terminated.
In step S8, the data string determined to match the function code data registered in advance in step S7 is stored (stored) in a predetermined address such as a RAM in the microcomputer 21 as the received function code data. .
Next, in step S9, a control process (notification (1)) for notifying that a signal having the same specification as the appropriate signal (that is, the appropriate specification) has been received is performed. In this case, specifically, the buzzer 30 is operated to generate a buzzer sound, or (or in addition to) the lamp 32 is lit or blinked. Note that the type and manner of notification may be varied in accordance with the function code data stored in step S8 so that the received function code can be identified. For example, if the function code is data for locking the door, the buzzer 30 may be sounded, and if the function code is data for unlocking the door, the lamp 32 may be turned on. If the function code is data for locking the door, the buzzer 30 may be sounded once, and if the function code is data for unlocking the door, the buzzer 30 may be sounded twice.
[0013]
Next, in step S10, it is determined whether or not the monitor mode is further set in the inspection mode. If it is set, the process proceeds to step S11, and if it is not set, the series of processes is terminated. The monitor mode is also a specific operation mode different from the normal operation mode of the receiver 20, similarly to the inspection mode, and is provided, for example, as a mechanical switch (not shown) so as to be difficult for a normal vehicle user to operate. The configuration can be set for the microcomputer 21 by the operation of (omitted).
In step S11, a notification process (notification (2)) is performed in which the data of each code (ID code, rolling code, function code) stored in steps S6 and S8 is output in a form that can be discriminated.
[0014]
The notification (data output) in step S11 may be performed as raw data (as a sequence of “1” and “0” signals), or may be converted into hexadecimal numbers and output. Further, as an output medium, it may be performed via a display or a printer (not shown) connected to the receiver at the time of work or an existing one installed in the vehicle, or the buzzer 30 shown in FIG. The lamp 32 may be used for output. For example, if the buzzer 30 sounds once for a long time, it is “1”, and if the buzzer 30 sounds for a short time twice, it is “0”. If the data content is “110010”, the buzzer 30 The data content may be notified by sounding 30 as “long once, long once, short twice, short twice, long once, short twice” (same for lamps). It is also possible to make a notification by using a buzzer having a different tone color (sound level, etc.) or a lamp having a different color or direction of light emission. For example, if the content of the data is “110010”, the buzzer may be activated and notified as “high, high, low, low, high, low, high, low” (same for lamps). The data output here may be performed separately for each code, or the data of all the codes may be notified sequentially and sequentially. For example, when outputting to a display or a printer, it may be displayed or printed as “ID code = 110010”, “Rolling code = 101110”, “Function code = 000101”, or the data of each code is continuously displayed. Specifically, “110010101110000101” may be displayed or printed.
[0015]
According to the above control processing, the signal of the proper specification (in this case, the signal pulse width, the synchronization code, the total number of bits, the custom code, and the function code are all appropriate signals) with the inspection mode set. Is received at least in step 9 regardless of the ID code or rolling code data (1) (notifying that the function code received has been received, preferably in a form that allows the received function code to be identified) Is executed and the monitor mode is set, notification (2) (step S11) is performed in which the contents of the received data (in this case, the data of the ID code, rolling code, and function code) are output. .
[0016]
For this reason, in the remote control device for keyless entry of this example, for example, in a vehicle dealer, it is easy to analyze the content of the failure (confirming the individual operation of the transmitter and the receiver, and further transmitting / receiving Signal content).
In other words, the receiver of another vehicle (for example, an exhibition car or a test ride at a dealer) having the same configuration as that of the faulty vehicle and the radio signal is set to the inspection mode. Try sending a signal from the transmitter of the broken car to the receiver. Then, if the receiver of this other vehicle executes the notification (1), it will first be understood that a signal with an appropriate specification is transmitted from the transmitter of the faulty vehicle, and this notification can be made in a form in which the function code can be identified. If (1) is performed, it is further understood that the function code is appropriate for the operated switch. On the other hand, if the notification (1) is not performed or is not appropriate, a signal with an appropriate specification is not transmitted from the transmitter of the faulty vehicle, and further, an appropriate one corresponding to the switch operated by the function code. I understand that it is not. Further, when the notification (1) is performed, if the receiver of the other vehicle is set to the monitor mode and the same operation is performed, the notification (2) is transmitted from the transmitter of the failed vehicle. The contents of the received signal (in this case, the contents of the ID code, rolling code, and function code) are found. That is, in this way, it is possible to easily check the individual operation of the transmitter of the broken vehicle and the content of the signal transmitted from the transmitter without requiring a special inspection device.
[0017]
On the other hand, the receiver of the broken vehicle is set to the inspection mode while being attached to the broken vehicle, and a signal is transmitted from the transmitter of the other vehicle to the receiver. If the receiver of the broken car executes the notification (1), first, it is understood that the receiver of the broken car has properly received the signal of the proper specification, and this function code can be discriminated. If the notification (1) is properly performed, it can be seen that the function code is properly received and determined as corresponding to the operated switch. On the other hand, if the notification (1) is not performed or is not appropriate, reception is not performed despite the signal having the proper specification, and the function code is not properly determined in the receiver. I understand that. Furthermore, when the notification (1) is performed, if the receiver of the broken vehicle is set to the monitor mode and the same operation is performed, the notification is received by the receiver of the broken vehicle by the notification (2). The contents of the signal (in this case, the contents of the ID code, rolling code, and function code) are determined. That is, in this way, it is possible to easily check the individual operation of the receiver of the broken vehicle and the content of the signal received by the receiver without requiring a special inspection device and removing the receiver.
[0018]
Therefore, according to this example, when a failure occurs where the remote control device of any vehicle does not function, whether the transmitter of the device is broken or the receiver is broken is normal. Whether there is a failure (ie, a failure other than the remote control device), some switches of the transmitter are partially broken, or a device on the vehicle side (for example, an actuator or a harness of a locking device) It is possible to easily and reliably determine whether or not the device is out of order. This facilitates trouble diagnosis work at dealers, etc., and also makes it easy to deal with troubles at the lowest cost by repairing only the trouble points. Furthermore, the maintenance cost borne by the vehicle user can be reduced.
In particular, if the contents of signals transmitted and received are output using the function of the monitor mode, the details of the failure can be analyzed more finely and with high reliability from another aspect. For example, because the rolling code has an abnormally large value, or because the ID code or function code is not properly registered (or the data has been corrupted, etc.), the other parts are completely normal. However, even if the remote operation cannot be performed, it is easy to make a repair without waste by identifying the contents of the failure.
[0019]
In the device of this example, the above-described notification (1) and notification (2) can be performed only in a specific operation mode different from the normal operation mode of the receiver. This is as follows. Exerts a positive effect. In other words, if the above-mentioned notification is performed unconditionally (a configuration that is performed even in a normal operation state), the transmitter is operated for normal remote operation, or in a parking lot or the like. Even when a transmitter of the same specification of another vehicle is operated, the above notification is performed every time, which is troublesome, but if it is performed on condition that a specific operation mode is set, Trouble can be solved.
[0020]
In addition, this invention is not limited to the said example of a form, There can be various deformation | transformation and aspects. For example, the specification of the signal transmitted from the transmitter is not limited to the above embodiment. That is, in the above embodiment, the same specifications are assumed only when the data of the signal pulse width, the synchronization code, the total number of bits, the custom code, and the function code match the data preset in the receiver. Although the alerting | reporting of invention is performed, it is not limited to this. For example, the data of the custom code and the function code may be ignored, and the notification of the present invention may be performed even if these are different from those set in the receiver. Even in this case, transmission / reception at the transmitter or receiver is performed properly for signals with appropriate signal format or protocol specifications (ie, signal pulse width, synchronization code, and total number of bits in the above embodiment). Individual operation confirmation of whether or not there is possible is possible in the same manner, and failure handling becomes easy.
[0021]
In addition, it is not always essential to change the type or mode of notification according to the function code, or to notify so that the data content of the signal can be determined. Even if it is simply notified that the signal of the proper specification has been received (presence / absence of reception) by a simple operation of a lamp or the like (for example, one lighting), the basic transmission / reception function of the transmitter or receiver can be confirmed It is possible and useful individually.
In addition, when notifying the data content of the signal so that it can be discriminated, it is not limited to the mode of notifying only the data of the specific code as in the above-described embodiment, and for example, notifying all the data of the signal in a distinguishable manner. Good. For example, in the case of the above embodiment, all data in the data frame including the synchronization code and the custom code may be notified.
[0022]
Further, the transmitter may be further provided with a plurality of switches, and various types of function code data may be set correspondingly. For example, a window opening / closing switch that remotely controls the opening and closing of windows, an engine switch that remotely controls engine startup, a trunk opening and closing switch that remotely controls opening and closing of a trunk, and vehicles that are attacked by a thug Needless to say, a panic switch or the like for sounding the horn may be provided as appropriate.
In the present invention, a transmitter that wirelessly transmits a signal having a predetermined specification including a code (that is, a key code) unique to each device, and a key code included in the signal wirelessly transmitted from the transmitter is set. As long as the remote control device includes a receiver that performs a predetermined output on condition that the key code is supported, the remote control device can be applied to devices other than the keyless entry device of the vehicle.
[0023]
【The invention's effect】
When the receiver of the remote control device of the present invention receives a signal having the same specifications as the signal transmitted from the transmitter, even if the key code included in the received signal is different from the set key code, a notification is made. Notification is performed by means.
For this reason, it is possible to easily analyze the failure content (confirmation of individual operation of the transmitter and the receiver) as follows in a sales office that sells the device.
In other words, the receiver of another device (such as an exhibit at a sales office) that has the same radio signal specifications as the failed device is set to a specific operation mode as necessary, and the device that has failed for this receiver Try sending a signal from the transmitter. Then, if the receiver of this other device executes the notification, it can be understood that a signal of proper specification is first transmitted from the transmitter of the failed device. On the other hand, if the notification is not performed, it can be understood that the signal of the proper specification is not transmitted from the transmitter of the failed device. That is, in this way, it is possible to easily check the individual operation of the transmitter of the failed device without requiring a special inspection device.
[0024]
On the other hand, the receiver of the faulty device is set in a specific operation mode as necessary while being attached, and a signal is transmitted from the transmitter of the other device to this receiver. If the receiver of the failed device executes the notification, it can be understood that the receiver of the failed device properly receives the signal of the proper specification. On the other hand, if the notification is not performed, it can be understood that reception is not performed even though the signal is of a proper specification. That is, it is possible to easily check the individual operation of the receiver of the failed device without requiring a special inspection device and without removing the receiver.
Therefore, according to the present invention, when a failure occurs where the remote control device does not function, whether the transmitter of the device is broken or the receiver is broken, is it normal (i.e. Etc.) can be easily and reliably determined. This facilitates failure diagnosis work at equipment sales offices, etc., and also makes it easy to deal with failures at the lowest cost by repairing only the failure points. In addition, it is possible to reduce the equipment cost and the maintenance cost borne by the vehicle user.
[0025]
In particular,In the remote control device according to claim 1, as the notification by the notification means, notification of the data content included in the received signal is performed in a distinguishable manner. For this reason, if this notification is performed in the individual operation confirmation of the transmitter or receiver described above, the contents of the signal transmitted / received by the transmitter or receiver of the failed device are found. That is, in this way, it is possible to easily confirm the contents of the transmitted / received signal as well as the individual operation confirmation of the transmitter and receiver of the failed device without requiring a special inspection device.
Therefore, the details of the failure can be analyzed more finely and from another aspect with extremely high reliability, and it is extremely easy to perform a repair without waste, and the effect of the present invention becomes very remarkable.
[0026]
And claims2In the remote control device described,In addition to the key code, the transmitted / received signal includes a function code for instructing the type or content of the output of the receiver. As a notification by the notification means, the type of the function code included in the received signal is included. The notification performed in a different type or mode is executed accordingly. For this reason, if this notification is performed in the individual operation confirmation of the transmitter or receiver described above, it is further understood whether or not the function code to be transmitted / received is appropriate for the operated switch. In other words, without requiring a special inspection device, the individual operation of the receiver of the failed device is confirmed, and the signals transmitted and received by the transmitter and receiver have the proper contents for the function code, and It is possible to easily determine whether or not the determination has been made. Therefore, the failure analysis of the apparatus can be made finer in terms of the function code, and the effect of the present invention becomes more remarkable.
[0027]
Claims3In the described remote control device, the notification by the notification unit is performed only in a state where a specific operation mode different from the normal operation mode of the receiver is set. For this reason, the following effects are obtained. That is, if the above notification is made unconditionally (a configuration that is performed even in a normal operation state), when the transmitter is operated for normal remote operation, or when another device nearby is used. Even when a transmitter with the same specifications is operated, the above notification is made every time, which is troublesome. However, if a specific operation mode is set, this problem can be solved. it can.
