Description

  The present invention relates to an in-vehicle alarm system, and more specifically, even a person who is awake while navigating in a car such as a truck can be forced to wake up and sleep twice. The present invention relates to an in-vehicle alarm system that can surely prevent the above.

  For smooth logistics, long-distance transportation of goods by trucks is indispensable, but it is needless to say that it is a drowsy driving that should not be in that case. Therefore, drivers such as long-distance trucks are trying to park in a parking area as much as possible and take a nap in the car.

  However, there are restrictions on transportation time, and it is often impossible to oversleep. Therefore, it is conceivable to bring an alarm clock into the car, but in the case of a general alarm clock, you can stop the alarm by pressing the alarm release button, once you wake up with an alarm sound and press the alarm release button, Since the alarm sound does not sound, there is a risk of going to sleep twice if not fully awake. As a result, there are many cases of oversleeping and driving unreasonably in order to make up for the delay, resulting in danger and accidents.

  In the invention described in Japanese Patent Laid-Open No. 6-167580, a proposal has been made to eliminate the inconvenience of carrying an alarm clock or the like by adding an alarm function controlled by a speed detection device to the in-vehicle clock. . However, since the alarm function is canceled by performing the alarm canceling operation on the spot of the on-vehicle clock to which the alarm function is added, the effect of preventing double sleep cannot be expected.

JP-A-6-167580

  As described above, in the case of a vehicle-mounted watch with a conventional alarm function, the alarm function is canceled by performing an alarm canceling operation on the spot. It cannot be awakened and cannot be expected to prevent double sleep.

  Therefore, according to the present invention, when taking a nap in the vehicle, the alarm function cannot be completely canceled by simply performing the alarm canceling operation after waking up by an alarm sounding, and therefore, the person who is awake is not good. However, it is an object of the present invention to provide an in-vehicle alarm system that can be forced to wake up forcibly, prevent sleeping twice, and promote planned safe operation.

  The invention described in claim 1 for solving the above-described problem is that the snooze mode is entered in accordance with the alarm stop operation performed after the alarm sounding is started, and thereafter, the release control of the snooze mode is not performed until the movement of the vehicle is detected. This is an in-vehicle alarm system characterized in that it is not performed. Thereafter, the release control of the snooze mode may not be performed until at least one of the travel distance, the vehicle speed, and the engine speed exceeds a predetermined reference value.

  In one embodiment, the in-vehicle alarm system includes a time setting unit for setting an alarm ringing start time, an alarm control unit for controlling an alarm ringing operation, and an alarm in response to a drive command from the alarm control unit. An alarm driving unit for executing the sounding of the means, an alarm releasing means for temporarily stopping the alarm sounding, and a snooze control unit for transmitting a signal for stopping the sounding of the alarm means for a predetermined time to the alarm control unit; A circuit configuration including a condition monitoring unit that transmits a condition clear signal directly to the alarm control unit or via the snooze control unit.

  In one embodiment, the condition monitoring unit includes a vehicle motion data acquisition unit, a vehicle travel distance, a vehicle speed and an engine speed data acquisition unit, vehicle stop position information serving as a reference for comparison, a travel distance, a vehicle speed. And the engine speed storage unit, the acquired vehicle movement data, and the travel distance / vehicle speed / engine speed data and the reference vehicle stop position information / travel distance / vehicle speed / engine stored in the storage unit And a comparison unit for comparing the rotational speed data.

  In one embodiment, the condition monitoring unit senses the movement of the vehicle with an in-vehicle camera. The on-vehicle camera can be replaced with a camera mounted on a drive recorder.

  In one embodiment, mileage data is obtained from a mileage meter of the vehicle, vehicle speed data is obtained from the speedometer of the vehicle, and engine speed data is obtained from an engine revometer of the vehicle.

  In one embodiment, the setting at the start of alarm sounding in the time setting circuit is a setting by time and / or a setting by time elapsed from the setting time. In addition, the in-vehicle alarm system can be incorporated in a clock or a car navigation system installed in a vehicle, and the alarm ringing start time can be set only when the vehicle is stopped.

  In one embodiment, there may be provided forcibly releasing means for forcibly terminating the alarm sound and the snooze mode, and the vehicle alarm system may be manageable and controllable by remote operation. This remote operation may be performed by telematics.

  According to the vehicle-mounted alarm system according to the present invention, the alarm function is provided unless the alarm once sounds and the user releases the alarm and then moves the set distance and / or outputs the set speed. Since it cannot be canceled completely, the snooze function will continue. Therefore, even if it is a person with a bad awakening, there is an effect that it is possible to forcefully awaken. In addition, there were people who had fear of oversleeping and had accidents as a result of driving in a sleepy state in the past. You can take a good nap and eliminate the cause of the accident.

It is a schematic block diagram which shows the structural example of the vehicle-mounted alarm system which concerns on this invention. It is a flowchart for demonstrating operation | movement of the vehicle-mounted alarm system which concerns on this invention.

  Embodiments for carrying out the present invention will be described in detail with reference to the accompanying drawings. The in-vehicle alarm system according to the present invention enters the snooze mode in response to an alarm stop operation performed after the start of alarm sounding, and thereafter, until the movement of the vehicle is detected or after the movement of the vehicle is detected, The snooze mode release control is not performed until at least one of the travel distance, the vehicle speed, and the engine speed exceeds a predetermined reference value. In other words, in this system, it is determined that the driver is completely awake when the vehicle movement is sensed or the vehicle travel distance, vehicle speed, or engine speed exceeds a predetermined value. To do.

  FIG. 1 is a schematic block diagram showing a configuration example of an in-vehicle alarm system according to the present invention. As shown there, the system is configured to receive a command from the time setting unit 2 for setting the alarm ringing start time, the alarm control unit 3 for controlling the alarm ringing operation, and the alarm ( (Sounding means) The alarm drive unit 4 that performs the ringing of the alarm 5, the snooze control unit 6 that transmits a signal for stopping the alarm 5 ringing for a predetermined time to the alarm control unit 3, and the alarm control unit 3 directly Alternatively, a circuit configuration including a condition monitoring unit 7 that transmits the condition clear signal via the snooze control unit 6 is combined with the watch body 1. In one embodiment, it is combined with a car navigation system that is currently popular. The car navigation system here 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 is when the movement of the vehicle is sensed, or when the subsequent mileage, vehicle speed, and engine speed exceed a predetermined value. The alarm control unit 3 that has received this condition clear signal stops transmission of the alarm sounding command to the alarm driving unit 4, and hence the sounding of the alarm 5 stops completely thereafter. The condition monitoring unit 7 includes a vehicle movement sensing unit, a vehicle travel distance and vehicle speed data acquisition unit, a vehicle stop position information serving as a comparison reference, a travel distance and vehicle speed storage unit, and the acquired travel distance / A comparison unit that compares the vehicle speed data and the reference vehicle stop position information, travel distance, and vehicle speed data stored in the storage unit;

  Among the configurations of the present system, the configurations of the time setting unit 2, the alarm control unit 3, and the alarm driving unit 4 are basically the same as those employed in a general alarm clock. That is, the user of this system can arbitrarily set the time to wake up, in other words, the alarm ringing start time, by touch panel operation, button operation, dial operation, or the like. In the case of a normal alarm clock, for example, the time itself such as 10:30 is set. However, in this system, a time setting method such as one hour after the setting time can be adopted, and the user can select one of them. Can also be selected.

  The snooze control unit 6 can also employ 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 a cancel operation by the user's alarm canceling means 8 and exhibits a snooze function when there is no clearing of conditions described later within a predetermined time (for example, within 5 minutes). The alarm is sounded until the alarm is canceled by the user. Then, after the alarm canceling operation, when there is no condition clear described later within a predetermined time, the alarm is sounded again, and thereafter the same operation as described above is repeated.

  Some general clocks can be set to activate the snooze function when an alarm is set. However, in this system, the snooze function is indispensable. It's not a natural element.

  The condition monitoring unit 7 senses the movement of the vehicle after an alarm stop operation is performed in response to the alarm sound, and also detects the travel distance, the vehicle speed, and the engine speed of the vehicle. The travel distance data from the travel distance meter 9 of the vehicle can be used as travel distance data to be monitored, and the vehicle speed data from the speedometer 10 of the vehicle is used as the vehicle speed data. Further, 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 vehicle-mounted travel distance meter 9, the speedometer 10, and the engine speed meter 11, may be used. The entire system can be incorporated into an on-vehicle clock or a car navigation system.

  In addition, it is preferable to provide the forced cancellation | release means 12 directly connected to the alarm drive part 4 and the snooze control part 6 in this system. The alarm based on the present system continues to sound and snooze unless the above conditions are satisfied. For example, when the vehicle cannot be started due to a vehicle failure or the like, or when the vehicle cannot proceed due to a traffic jam or the like, the ringing does not stop. In such a case, even if the user is awake, the user must continue to listen to the alarm sound, which is undesirable from the user's mind. Therefore, it is preferable that the present system is provided with a forced release means 12 that is directly connected to and acts on the alarm driving unit 4 and the snooze control unit 6.

  As the forcible release means 12, for example, a method of stepping the brake strongly continuously 10 times or more, a method of opening and closing the door 5 times or more continuously, or a method of inputting a forced release code, etc. can be considered. It is not limited to.

  The system can also be controlled by remote operation. For the control, for example, telematics can be used. When this system is managed and controlled by remote operation using a mechanism such as telematics, for example, after the current location of the vehicle is clarified, the movement of the vehicle cannot be detected for a certain period of time. Such an alarm function can be activated to awaken the driver, and even when the alarm function is forgotten to be set, it can be dealt with. It is also possible to control the forced release means 12 by remote operation to release the alarm sound and the snooze mode.

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

First alarm ringing setting step (S10)
This step is a step in which each user sets an alarm ringing start time according to a scheduled wake-up time when taking a nap in a vehicle equipped with the in-vehicle alarm system according to the present invention. It is basically the same as what you usually do in a general alarm clock. As described above, the time is set by a time setting method such as 10:30 or a time setting method one hour after the setting time.

  In general, the snooze operation interval is set in advance, such as a 5-minute interval, and the specification cannot be arbitrarily set by the user, but can be arbitrarily changed by the user. It is also possible to configure. In this case, the snooze operation interval can be set at this stage. Further, the reference values of the vehicle travel distance and the vehicle speed monitored by the condition monitoring unit 7 are generally set in advance. However, the specification can be arbitrarily changed by the user each time.

Primary alarm ring release operation step (S20)
When the time set in the above step is reached, the alarm 5 starts sounding, and this alarm 5 continues until the user performs the canceling operation of the alarm canceling means 8. The release operation is performed by a touch operation or a button operation on the clock screen. With the release operation, the alarm means 5 stops ringing and the operation of the snooze control unit 6 is started.

Snooze mode step (S30)
The snooze control unit 6 instructs the alarm driving unit 4 to sound the alarm 5 unless a condition clear signal is received from the condition monitoring unit 7 within a set time after the start of the operation. Until the release operation is performed, the alarm 5 continues to sound. When an alarm cancel operation is performed by the user, the alarm 5 is temporarily stopped and a cancel command signal from the condition monitoring unit 7 is waited for. 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 to operate when an alarm release operation is performed with respect to the first alarm ringing, and at least one of sensing of the movement of the vehicle, or subsequent driving distance of the vehicle, vehicle speed, and engine speed is performed. Data for 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 exceed the reference value, snooze control 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, the snooze control unit 6 stops its operation, and accordingly, the operation of the alarm control unit 3 also stops. Thereafter, 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 the safety of driving, it is preferable to automatically and completely stop immediately after receiving the release command signal.

  This system is usually incorporated in a vehicle-mounted watch, but can also be incorporated in a car navigation system (including both a vehicle-mounted device and a portable device). Moreover, it can also be comprised as an independent system separate from a vehicle-mounted timepiece or a car navigation system.

  Furthermore, a wireless communication device may be provided in the system, and the system may be controlled by remote operation. To that end, for example, telematics can be used. When managing and controlling by remote operation such as telematics, it becomes possible to cope with a case where the alarm function is forgotten to be set or a state where the above conditions cannot be cleared.

  Although the invention has been described in some detail with its most preferred embodiments, it is evident that a wide variety of embodiments can be constructed without departing from the spirit and scope of the invention. Accordingly, the invention is not limited to that particular embodiment, except as limited in the appended claims.
