TECHNICAL FIELD OF THE INVENTION
The present invention relates to a vehicle security device that can be remotely controlled using wireless communication.
[0002]
[Prior art]
2. Description of the Related Art Conventionally, a vehicle security device for preventing theft or aiming of a vehicle is known. In this conventional device, a warning operation is started when a predetermined time elapses after the driver turns on the switch. If the door or trunk is scoured or the windshield is broken during the alert operation, the tires are locked or the fuel injection device is controlled to make the vehicle unable to travel or difficult to travel. By sounding an alarm, a third party is notified that an abnormality has occurred.
[0003]
[Problems to be solved by the invention]
On the other hand, in recent years, it has become possible to set or cancel a warning operation of a vehicle security device by remote control using wireless communication. However, when setting or canceling the alert operation by remote control, the following security problems occur.
[0004]
For example, in the conventional device, a predetermined period of time has to be elapsed from when the driver instructs the start of the alert operation to when the alert operation is actually started. This is because the time until the passenger gets off the vehicle, the time to take out the luggage from the trunk, and the like are taken into consideration. However, when the security operation of the security device is started from a place remote from the vehicle by remote control, it is necessary to start the security operation as soon as possible. For this reason, it is not preferable from the viewpoint of crime prevention that a predetermined time must always elapse at the start of the alert operation.
[0005]
Also, for example, when a device that instructs the security device to start a warning operation, such as a portable device, reaches a third party's hand due to theft, loss, or the like, the third person is away from the vehicle, The security operation of the security device can be easily released, which is not preferable for security.
[0006]
The present invention has been made in view of the above problems, and has as its object to provide a vehicle security device capable of realizing robust security even in remote control using wireless communication.
[0007]
[Means for Solving the Problems]
In order to achieve the above object, the vehicle security device according to claim 1 has security means for performing a security operation of the vehicle, and two operation modes of a security mode and a non-security mode. Control means for activating the crime prevention means, instruction means for instructing change of the operation mode of the control means by radio, and control means receiving an instruction from the instruction means for changing the operation mode to the alert mode. And setting means for setting a delay time until the time is changed.
[0008]
As described above, in the vehicle security device of the present invention, the setting unit sets the delay time from when the control unit receives the instruction to change the operation mode to the alert mode from the instruction unit until the operation mode is changed to the alert mode. Can be set by When receiving an instruction to change the operation mode to the alert mode from the instruction unit, the control unit changes the operation mode to the alert mode after the delay time set by the setting unit has elapsed.
[0009]
Thereby, for example, when the driver changes the operation mode of the control unit to the alert mode from the inside of the vehicle or near the vehicle by the portable device or the like, by setting a long delay time, the passenger gets off the vehicle. Time, and time for loading and unloading luggage can be secured. On the other hand, for example, when the driver changes the operation mode of the vehicle security device to the alert mode from a place away from the vehicle by using a mobile phone or the Internet, the alert time can be quickly set by setting a short delay time. Can be transferred to. This makes it possible to realize robust security even in remote control using wireless communication.
[0010]
It is desirable that the setting means can set the delay time to zero. For example, when the driver changes the operation mode of the control unit to the alert mode from a place away from the vehicle by using a mobile phone or the Internet, the delay time is set to zero so that the control unit operates in the operation mode. Can be immediately changed to the alert mode, which is preferable for crime prevention.
[0011]
Further, the vehicle security device according to the third aspect has a security device for performing a security operation of the vehicle and two operation modes of a security mode and a non-security mode, and activates the security device during the security mode. Control means, changing means for changing the operation mode of the control means, and wirelessly prohibiting the change means from changing the operation mode of the control means to the non-alert mode or releasing the prohibition of the change to the control means. Instruction means for instructing.
[0012]
As described above, in the vehicle security device of the present invention, the instruction unit can prohibit the changing unit from changing the operation mode of the control unit to the non-alert mode, and can cancel the prohibition. Therefore, for example, even when a portable device or the like, which is a changing unit, is passed to a third party's hand due to theft or loss, the operation mode of the control unit is changed from the portable unit to the non-alert mode by the instruction unit. Can be banned. As a result, a third party cannot change the operation mode of the control means to the non-alert mode by the portable device, and it is possible to realize more robust security.
[0013]
According to a fourth aspect of the present invention, the change unit may include a notifying unit for notifying whether or not the change of the operation mode of the control unit to the non-alert mode by the unit is prohibited by the instruction unit. desirable. Thereby, for example, even when the above-described portable device or the like reaches the hands of a third party, the third party determines whether or not the operation mode of the control unit can be changed to the non-alert mode by the portable device. We can know and can expect crime deterrent effect.
[0014]
BEST MODE FOR CARRYING OUT THE INVENTION
(1st Embodiment)
FIG. 1 is a block diagram showing the overall configuration of the vehicle security device according to the first embodiment of the present invention.
[0015]
The security control unit 1 is mounted on a vehicle to perform a security operation, and includes an ECU 2, an approach sensor 31, a glass break sensor 32, an intrusion sensor 33, a tilt sensor 34, a starting lock device 4, an alarm device 5, and a communication circuit 6. It is composed of
[0016]
The ECU 2, which is a control means, has two operation modes, a security mode and a non-security mode, and performs a security operation on the vehicle when the security mode is set.
[0017]
Specifically, during the alert mode, the ECU 2 constantly monitors outputs from the approach sensor 31, the glass break sensor 32, the intrusion sensor 33, and the tilt sensor 34. When it is detected from these sensor outputs that the door or trunk has been scoured or the windshield has been broken by a third party, an operation is instructed to the starting lock device 4 and the alarm device 5 as security means. I do. As a result, the starting lock device 4 locks the tires to make the vehicle start running, and the warning device 5 issues a warning to notify the surroundings of the occurrence of an abnormality. Note that these security operations are not performed during the non-alert mode. In addition, as a method of disabling the vehicle, this may be performed by controlling a transmission or the like. The vehicle may be made difficult to travel by controlling the output of the fuel injection device. Of course, these may be used in combination.
[0018]
Each time the ECU 2 receives the operation mode change instruction, the ECU 2 changes the operation mode being executed. At this time, if the instruction received by the ECU 2 is an instruction to change the operation mode to the alert mode, the ECU 2 changes the operation mode to the alert mode after a predetermined delay time has elapsed. Otherwise, that is, if the instruction is to change the operation mode to the non-vigilance mode, the ECU 2 immediately changes the operation mode to the non-vigilance mode. The delay time is stored in the ECU 2, but can be changed from the mobile phone 7.
[0019]
The communication circuit 6 receives the instruction to change the operation mode and the instruction to change the delay time transmitted from the mobile phone 7 and outputs them to the ECU 2.
[0020]
The mobile phone 7 as the instruction means and the setting means instructs the ECU 2 to change the operation mode and change the delay time.
[0021]
Specifically, the driver first makes a call from the mobile phone 7 to the management center 72 via the base station 71. Then, the personal identification number and the vehicle number of the target vehicle are input from the mobile phone 7 and transmitted to the management center 72. The management center 72 checks whether the personal identification number transmitted from the mobile phone 7 matches a preset personal identification number, and when the personal identification number matches, the security center of the vehicle security device mounted on the target vehicle is checked. Permits change of operation mode and change of delay time. As a result, the driver can change the operation mode and the delay time of the vehicle security device mounted on the target vehicle from the mobile phone 7 by inputting the command numbers corresponding thereto. .
[0022]
When the driver instructs the mobile phone 7 to change the operation mode or change the delay time, the management center 72 sends the operation mode change instruction or the change via the base station 73 closest to the place where the target vehicle is stopped. An instruction to change the delay time is transmitted to the communication circuit 6. The instruction to change the operation mode and the instruction to change the delay time may be given from the Internet or the like, or may be given directly from a portable device that can be remotely operated by wireless. Of course, these may be used in combination.
[0023]
FIG. 2 is a flowchart illustrating a process in which the vehicle security device of the first embodiment changes the operation mode. The process of this flowchart is executed each time the driver instructs the mobile phone 7 to change the operation mode of the vehicle security device mounted on the target vehicle.
[0024]
In step 201, it is determined whether or not an instruction to change the operation mode to the alert mode has been given. If it is instructed to change the operation mode to the alert mode, the process proceeds to step 202. If not, that is, if it is instructed to change the operation mode to the non-vigilance mode, the process proceeds to step 206, changes the operation mode to the non-vigilance mode, and ends the processing.
[0025]
In step 202, it is determined whether or not the delay time when changing the operation mode to the alert mode is set to zero. As described above, when the delay time is set to zero, the operation mode is immediately changed to the alert mode, so that, for example, the driver can control the control means from a place away from the vehicle by using a mobile phone or the Internet. When changing the operation mode to the alert mode, the alert mode can be changed without waiting for a predetermined time to elapse, which is preferable for crime prevention. If the delay time read in step 201 is zero, the process proceeds to step 206, where the operation mode is immediately changed to the alert mode, and the process ends. Otherwise, go to step 203.
[0026]
In step 203, the delay time counter inside the ECU 2 is reset. The delay time counter is a counter that counts the time that has elapsed since the ECU 2 received the instruction to change the operation mode to the alert mode. In step 204, the value of the delay time counter reset in step 203 is incremented by one.
[0027]
In step 205, it is determined whether or not the value of the delay time counter is equal to the delay time read in step 201. As described above, the time elapsed since the ECU 2 received the instruction to change the operation mode to the alert mode is counted, and the operation mode is changed to the alert mode after the delay time elapses. From the vicinity, when changing the operation mode of the vehicle security device to the alert mode by a portable device or the like, it is possible to secure time for the passenger to get off, time for loading and unloading luggage, and the like. It is. If the value of the delay time counter is equal to the delay time, the process proceeds to step 206, where the operation mode is changed to the alert mode, and the process ends. If not equal, the process returns to step 204, and the processing of steps 204 to 205 is repeated until the value of the delay time counter becomes equal to the delay time read in step 201.
[0028]
Thus, in the vehicle security device of the present embodiment, the delay time from when the ECU 2 is instructed to change the operation mode to the alert mode to when the ECU 2 is changed to the alert mode can be set by the mobile phone 7. . When receiving an instruction from the mobile phone 7 to change the operation mode to the alert mode, the ECU 2 changes to the alert mode after a set delay time has elapsed. This makes it possible to realize robust security even in remote control using wireless communication.
(2nd Embodiment)
FIG. 3 is a block diagram showing the overall configuration of the vehicle security device according to the second embodiment of the present invention. As shown in FIG. 3, the vehicle security device of the present embodiment is different from the first embodiment in that a portable device 8 for instructing an operation mode change of the ECU 2 is provided in the first embodiment.
[0029]
The portable device 8 serving as a change unit is a portable device having a communication function, and includes a mode change key and a change prohibition LED 83.
[0030]
The mode change key includes an on key 81 and an off key 82. The on key 81 is a key for instructing to change the operation mode of the ECU 2 to the alert mode, and the off key 82 is a key for instructing to change the operation mode of the ECU 2 to the non-alert mode. When the holder of the portable device 8 presses these keys, an instruction corresponding to the pressed key is transmitted to the communication circuit 6 by radio. The communication circuit 6 receives these instructions and transmits them to the ECU 2.
[0031]
A change prohibition LED 83 serving as a notification unit indicates whether or not the operation mode of the ECU 2 can be changed by the mode change key. When the change prohibition LED 83 is off, the operation mode of the ECU 2 can be changed to the non-warning mode by the off key 82. On the other hand, when the change prohibition LED 83 is lit, the operation mode of the ECU 2 cannot be changed to the non-warning mode by the off key 82. The operation mode of the ECU 2 can be changed to the alert mode at any time by using the on-key 81 regardless of whether the change inhibition LED 83 is turned on or off.
[0032]
An instruction to prohibit the mobile device 8 from changing the operation mode of the ECU 2 to the non-alert mode or cancel the operation is issued by the mobile phone 7 as an instruction unit. Specifically, the driver first makes a call from the mobile phone 7 to the management center 72 via the base station 71 and inputs a personal identification number and a vehicle number of the target vehicle from the mobile phone 7. The management center 72 checks whether the personal identification number transmitted from the mobile phone 7 matches a preset personal identification number, and when the personal identification number matches, the operation mode of the portable device 8 to the non-alert mode is performed. It is permitted that the mobile phone 7 gives an instruction to prohibit the change or cancel the prohibition.
[0033]
When the driver prohibits the mobile phone 7 from changing the operation mode to the non-alert mode by the mobile device 8, the management center 72 transmits the information via the base station 73 closest to the place where the target vehicle is stopped. It instructs the ECU 2 via the communication circuit 6 not to accept the operation mode change to the non-alert mode by the portable device 8. As a result, the ECU 2 does not accept any operation mode change to the non-alert mode by the portable device 8. Then, the ECU 2 transmits an instruction to light the change inhibition LED 83 to the portable device 8 via the communication circuit 6. When the portable device 8 receives the instruction, the change inhibition LED 83 is turned on, and the off key 82 notifies the owner of the portable device 8 that the operation mode of the ECU 2 cannot be changed to the non-alert mode.
[0034]
Thereafter, when the driver permits (removes the prohibition) the operation mode change from the mobile phone 7 to the non-alert mode by the mobile device 8, the management center 72 instructs the ECU 2 to operate the non-alert mode by the mobile device 8. Tell them to accept the change again. Then, the ECU 2 transmits an instruction to turn off the change prohibition LED 83 to the portable device 8 via the communication circuit 6. When the portable device 8 receives the instruction, it turns off the change inhibition LED 83 and notifies the owner of the portable device 8 that the operation mode can be changed to the non-warning mode by the off key 82.
[0035]
Thereby, for example, even when the portable device 8 reaches the hand of a third party, the third party can know from the change inhibition LED 83 whether or not the operation mode of the ECU 2 can be changed to the non-alert mode. It can be expected to have a deterrent effect on crime.
[0036]
In addition, as a method of notifying the owner of the portable device 8 whether or not the change of the operation mode to the non-warning mode by the portable device 8 may be notified by blinking the change inhibition LED 83. Alternatively, the portable device 8 may be provided with a display panel, and this may be notified by displaying the display panel. Further, the setting for prohibiting the change of the operation mode to the non-warning mode by the portable device 8 or for permitting (releasing the prohibition) may be performed from the Internet or the like.
[0037]
FIG. 4 is a flowchart illustrating a process in which the vehicle security device according to the second embodiment changes the operation mode. As shown in FIG. 4, in the flowchart of the present embodiment, in the flowchart of FIG. 2 of the above-described first embodiment, whether or not an instruction to change the operation mode of the ECU 2 to the non-alert mode is given from the portable device 8 And a step of determining whether changing the operation mode of the ECU 2 to the non-warning mode by the portable device 8 is prohibited. In other words, the processing of steps 401 to 406 is the same as the processing of the flowchart of FIG. 2 in the first embodiment, and a description thereof will be omitted. The process of this flowchart is executed every time an instruction to change the operation mode of the ECU 2 is issued.
[0038]
In step 407, it is determined whether or not an instruction to change the operation mode of the ECU 2 to the non-alert mode has been given from the portable device 8. If the instruction is given from the portable device 8, the process proceeds to step 408. If not, the process proceeds to step 406, the operation mode is changed to the non-alert mode, and the process ends.
[0039]
In step 408, it is determined whether or not the portable device 8 is prohibited from changing the operation mode of the ECU 2 to the non-warning mode. If the change from the portable device 8 is prohibited, the process ends. If not, the process proceeds to step 406, the operation mode is changed to the non-alert mode, and the process ends.
[0040]
As described above, in the vehicular security device of the present embodiment, the change of the operation mode to the non-alert mode by the portable device 8 can be prohibited or canceled by the portable phone 7 or the Internet. Therefore, for example, even when the portable device 8 reaches the hands of a third party due to theft, loss, or the like, changing the operation mode of the portable device 8 to the non-alert mode from the portable phone 7 or the Internet is prohibited. It is possible to realize more robust security.
