Description

  The present invention relates to an in-vehicle alarm system, and more specifically, a person who is sleeping in a car such as a truck or the like and who is not awake can be forced to surely wake up and sleep twice The present invention relates to an in-vehicle alarm system that can reliably prevent

  For smooth logistics, long distance transportation of goods by truck etc. is an indispensable place, but it goes without saying that it is a drowsy driving that should not be done in that case. Therefore, drivers such as long distance trucks are trying to park in the parking area etc. as much as possible and take a nap in the car.

  However, transportation time is also limited, so it is often difficult to go to bed. Therefore, it is conceivable to bring an alarm clock into the car, but in the case of a general alarm clock, it is possible to stop the alarm by pressing the alarm release button, and wake up once by the alarm sound and press the alarm release button. As the alarm sound does not sound, there is a risk of sleeping twice when not awake enough. As a result, there are many cases in which excessive driving causes unreasonable driving to recover from the delay, leading to danger and leading to an accident.

  In the invention described in JP-A-6-167580, a proposal has been made to add an alarm function controlled by a speed detection device to an on-vehicle watch to eliminate the inconvenience of carrying an alarm clock or the like. . However, since the alarm function is canceled by performing the alarm release operation on the spot, it is not possible to expect the effect of preventing sleeping twice.

JP-A-6-167580

  As described above, in the case of a conventional on-vehicle watch with a wake-up function, the alarm function is canceled by performing the alarm release operation on the spot, so the person who is not awake can be surely forced. It can not be awakened and can not be expected to prevent sleeping twice.

  Therefore, when taking a nap in a car, the present invention can not completely cancel the alarm function simply by performing the alarm cancellation operation after waking up by the alarm ringing, and hence the person who is not awake. However, it is an object of the present invention to provide an on-vehicle alarm system which can surely wake up surely and prevent sleeping twice and promote planned safe operation.

The invention according to claim 1 for solving the above-mentioned problems is a snooze mode following an alarm stop operation performed after the start of an alarm ringing, and thereafter , at least one of travel distance, vehicle speed and engine speed is a predetermined one. The vehicle alarm system is characterized in that the release control of the snooze mode is not performed until the reference value is exceeded .

  In one embodiment, the condition monitoring unit senses the movement of the vehicle by an on-vehicle camera. And the said vehicle-mounted camera can also be substituted by the camera mounted in the drive recorder.

  In one embodiment, travel distance data is acquired from a travel distance meter of a vehicle, vehicle speed data is acquired from a speedometer of the vehicle, and engine speed data is acquired from an engine revolution meter of the vehicle.

  In one embodiment, the setting at the start of the alarm ringing in the time setting circuit is a setting based on time and / or a setting based on an elapsed time from the setting time. Further, the present alarm system can be incorporated into a clock or car navigation system provided in a vehicle, and the alarm ringing start time can be set only when the vehicle is stopped.

  In one embodiment, the alarm ringing and the forcible cancellation means for forcibly terminating the snooze mode may be provided, and the in-vehicle alarm system may be managed and controlled by remote control. This remote control may be performed by telematics.

  According to the in-vehicle alarm system according to the present invention, the alarm function is activated unless the user moves the set distance after the alarm sounds once and the user performs the alarm release operation, and / or unless the set speed is output. The snooze function will continue because it can not be completely released. Therefore, there is an effect that even a person who is not awake can be forced to surely wake up. In addition, there were people in the past who were afraid of oversleeping and continued to drive in a sleepy state, resulting in an accident in the past, but the present invention can eliminate anxiety about awakening, so quality can be assured with ease. You can expect a good nap and eliminate the cause of the accident.

It is a schematic block diagram showing an example of composition of an alarm system for vehicles concerning the present invention. It is a flowchart for demonstrating the operation | movement of the vehicle-mounted alarm system which concerns on this invention.

  DETAILED DESCRIPTION OF THE INVENTION Embodiments of the present invention will be described in detail with reference to the attached drawings. The vehicle alarm system according to the present invention enters the snooze mode in response to the alarm stop operation performed after the start of the alarm ringing, and thereafter, until the vehicle movement is sensed or after the vehicle movement is sensed, The present invention is characterized in that the release control of the snooze mode is not performed until at least one of the travel distance, the vehicle speed, and the engine speed exceeds a predetermined reference value. That is, in the present system, it is determined that the driver is completely awake when either the movement of the vehicle or the distance traveled by the vehicle, the vehicle speed, or the engine speed exceeds a predetermined value. It is to do.

  FIG. 1 is a schematic block diagram showing a configuration example of an alarm system for a vehicle according to the present invention. As shown therein, the system receives a command from the time control unit 2 for setting the alarm ringing start time, the alarm control unit 3 for controlling the alarm ringing operation, and the alarm control unit 3 and generates an alarm ( Ringing means) 5, a snooze control unit 6 for transmitting a signal to stop the ringing of the alarm 5 for a predetermined period of time to the alarm control unit 3, and the alarm control unit 3 directly to the alarm control unit 3. Alternatively, the circuit configuration including the condition monitoring unit 7 for transmitting the condition clear signal via the snooze control unit 6 is combined with the watch main body 1. In one embodiment, it is combined with car navigation systems, which are now popular. The car navigation system in this case includes not only a car navigation system attached to a vehicle but also a portable car navigation system.

  The condition clear signal transmitted from the condition monitoring unit 7 to the alarm control unit 3 indicates that the movement of the vehicle has been detected, or that the distance traveled by the vehicle, the vehicle speed, or the engine speed has exceeded a predetermined value. The alarm control unit 3 receives the condition clear signal, and thereafter stops transmission of the alarm ringing command to the alarm driving unit 4, and thereafter the ringing of the alarm 5 is completely stopped. The condition monitoring unit 7 detects the movement of the vehicle, the data acquisition unit of the travel distance and the vehicle speed of the vehicle, the stop position information of the vehicle as a comparison reference, the storage unit of the travel distance and the vehicle speed, and the acquired travel distance · A comparison unit is provided which compares vehicle speed data with stop position information, traveling distance, and vehicle speed data of a reference vehicle stored in the storage unit.

  Among the configurations of the present system described above, the configurations of the time setting unit 2, the alarm control unit 3 and the alarm drive unit 4 are basically the same as the configurations of those employed in general alarm clocks. That is, the system user can arbitrarily set the time to wake up by touch panel operation, button operation, dial operation, etc., in other words, the alarm ringing start time. In the case of a normal alarm clock, for example, the time itself such as 10:30 is set, but in this system, a time setting method such as one hour after the set time can be adopted, and the user can either You can also choose to

  The snooze control unit 6 can also adopt a configuration incorporated in a general alarm clock, a mobile phone or the like. The snooze control unit 6 starts its operation in response to the user's release operation by the alarm release means 8 and exhibits the snooze function when the condition clear described later does not occur within a predetermined time (for example, within 5 minutes). The alarm ringing is executed, and the alarm ringing continues until the user releases the alarm. Then, after the alarm release operation, if there is no condition clear described later within a predetermined time, the alarm ringing is executed again, and the same operation as described above is repeated thereafter.

  Although some clocks and the like can be selected whether to activate the snooze function at the time of alarm setting, the snooze function is essential in this system, and it is possible for the user to select one. It is not an essential element.

  The condition monitoring unit 7 detects the movement of the vehicle after the alarm stop operation is performed for the alarm ringing, and detects the traveling distance of the vehicle, the vehicle speed, and the engine speed, and whether they exceed a predetermined value Whether the vehicle is compared or not can be determined, but traveling distance data from the traveling distance meter 9 of the vehicle can be used as traveling distance data to be monitored, and vehicle velocity data from the speedometer 10 of the vehicle can be used as vehicle velocity data. The engine speed data from the engine speed meter 11 can also be used. Of course, a distance meter unique to the present system, a speedometer, and the like which are separate from the on-vehicle travel distance meter 9, the speedometer 10, and the engine speed meter 11 may be used. In addition, this system can be integrated into an on-board watch or car navigation system.

  In the present system, it is preferable to provide forcible release means 12 which is directly connected to and operates on the alarm drive unit 4 and the snooze control unit 6. The alarm based on this system is ringing and the snooze mode is continued as long as the above conditions are not satisfied. For example, when the vehicle can not be launched due to a failure of the vehicle or the like, the ringing does not stop even when the vehicle can not progress due to traffic congestion or the like. In such a case, even when the user is awake, he must continue to hear the alarm sound, which is not preferable for the user's mind. Therefore, in the present system, it is preferable to provide the forced release means 12 which is directly connected to the alarm drive unit 4 and the snooze control unit 6 and acts.

  For example, a method of stepping on the brake ten times or more continuously, a method of opening and closing a door five times or more continuously, or a method of inputting a forced cancellation code can be considered as the forced cancellation means 12. It is not limited to

  The system can also be made controllable remotely. For the control, for example, telematics can be used. When managing and controlling this system by remote control by a mechanism such as telematics, for example, after clarifying the current location of the vehicle, if the movement of the vehicle can not be detected for a certain period of time, this system can be remotely controlled. The alarm function can be activated to awaken the driver, and it is possible to cope with the case where the alarm function is forgotten to be set. It is also possible to control the forced release means 12 by remote control and release the alarm ringing and the snooze mode.

  Next, the process flow of the in-vehicle alarm system according to the present invention having the above-described configuration will be described step by step with reference to the flow chart of FIG.

First alarm ringing setting step (S10)
This step is a step of setting the alarm ringing start time according to the wake-up scheduled time when each user takes a nap in the vehicle equipped with the on-vehicle alarm system according to the present invention, and the operation for this is It is basically the same as what you usually do in ordinary alarm clocks. As described above, the setting of the time in this case is performed by, for example, a time setting method such as 10:30 or a time setting method such as one hour after the setting time.

  In general, the interval between snooze operations is, for example, a specification that is set in advance and can not be arbitrarily set by the user, such as an interval of 5 minutes, but the user can arbitrarily change it. It is also possible to configure. The setting of the snooze operation interval in that case can be performed at this stage. The reference value of the travel distance and the vehicle speed of the vehicle monitored by the condition monitoring unit 7 is also generally set in advance, but may be set to a specification that can be arbitrarily changed by the user each time.

Primary alarm ringing release operation step (S20)
When the time set in the above step comes, the ringing of the alarm 5 starts, and the ringing of the alarm 5 continues until the user performs the release operation of the alarm release means 8. The release operation is performed by touch operation or button operation of the clock screen. Along with the release operation, the ringing of the alarm means 5 is stopped and the operation of the snooze control unit 6 is started.

Snooze mode step (S30)
The snooze control unit 6 instructs the alarm drive unit 4 to execute the ringing of the alarm 5 as long as the snooze control unit 6 does not receive the condition clear signal from the condition monitoring unit 7 within the set time after the start of the operation. The ringing of the alarm 5 is continued until the release operation is performed. Then, when an alarm release operation is performed by the user, the ringing of the alarm 5 is paused, and a release command signal from the condition monitoring unit 7 is awaited. Thereafter, when the release command signal from the condition monitoring unit 7 is not received within the set time, the above operation is repeated.

Condition clear monitoring step (S40)
The condition monitoring unit 7 starts the operation by performing the alarm release operation for the first alarm ringing, and detects the movement of the vehicle, or thereafter, at least any one of the traveling distance of the vehicle, the vehicle speed, and the engine speed. Data about one is acquired, and those values are compared with a preset reference value (or the stop position of the vehicle), and when it is determined that one or more of them exceeds the reference value, snooze control is performed. A release command signal is transmitted to the unit 6.

Alarm ringing complete release step (S50)
When the snooze control unit 6 receives the release command signal, it stops its operation, and accordingly the operation of the alarm control unit 3 also stops, and thereafter the transmission of the drive signal to the alarm drive unit 4 is interrupted, and the alarm function in this system is Stop completely. In consideration of safety of driving, it is preferable to automatically stop the vehicle immediately after receiving the release command signal.

  The system is usually incorporated into an on-board watch, but can also be incorporated into a car navigation system (including both in-vehicle and portable). Also, it can be configured as an independent system separate from the on-vehicle clock and the car navigation system.

  Furthermore, a wireless communication device may be provided in the present system, and the present system may be controlled by remote control. For that purpose, telematics can be used, for example. In the case of management and control by remote control such as telematics, it becomes possible to cope with the case where the alarm function is forgotten to be set or the state where the respective conditions can not be cleared.

  Although the invention has been described in some detail with respect to its most preferred embodiments, it will be apparent that widely different embodiments can be configured without departing from the spirit and scope of the invention. Accordingly, the present invention is not to be limited to any particular embodiment except as set forth in the appended claims.
