[Prior art]

 BACKGROUND ART A vehicle speed warning device that issues an alarm when a vehicle speed exceeds a predetermined speed, for example, 100 km / h, has been widely put into practical use. A speed alarm device generally includes a transmission unit associated with a speed indicating device such as a speedometer, and an alarm unit including a buzzer, chime, lamp, or the like for issuing an alarm to the driver. When it exceeds the limit, the alarm unit is operated continuously or intermittently (see, for example, JP-A-58-141945).

A highway driving recognition device configured to recognize the condition or type of a road on which a vehicle travels is disclosed in Japanese Utility Model Laid-Open No. 2-71213. The recognition device disclosed in this publication recognizes the condition of a road on which a vehicle is traveling, that is, the distinction between a general road and a highway, based on various conditions such as a temporary stop of a vehicle, a window opening / closing operation, and a vehicle speed. The road condition determined by the recognition device is used as a driving condition of the vehicle for controlling the automatic transmission or the variable suspension.

[0004]

[Problems to be solved by the device]

 The driver generally leaves the highway and immediately after entering the highway, the vehicle is traveling at a comparatively high speed, for example, about 50 to 60 km / h, but the driver feels that the vehicle is very slow or slow. Be aware of the feeling of acceleration. This illusion is considered to be due to the sense of speed being paralyzed to some extent as a result of traveling at high speed on the highway for a relatively long time.

On the other hand, the above-mentioned vehicle speed warning device is conventionally set to issue a warning when the vehicle speed exceeds a certain predetermined speed, for example, 100 km / h. It only warns the driver of a significant speed increase or excessive vehicle speed and cannot issue an alarm to correct such an illusion of a driver. The present invention has been made in view of the above points, and an object thereof is to correct a driving feeling or an acceleration feeling felt by a driver immediately after finishing a high speed driving for a relatively long time. Another object of the present invention is to provide a vehicle speed warning device capable of issuing a warning to the driver.

[0006]

[Means and Actions for Solving the Problems]

 In order to solve the above problems, the present invention is configured as follows. A vehicle speed alarm device according to the present invention comprises an alarm device and a control device for controlling the operation of the alarm device. The control device comprises a vehicle speed detecting means for detecting a vehicle speed and a detection result of the vehicle speed detecting means. A high speed traveling determining means for determining high speed traveling based on the above, and a low speed traveling determining means for determining a transition from high speed traveling to low speed traveling based on the detection result of at least one of the vehicle speed detecting means and the high speed traveling determining means, An alarm start speed changing means is provided for reducing the alarm start speed of the alarm device when the low speed travel determination means determines the transition from high speed travel to low speed travel.

According to the speed warning device for a vehicle having the above-described configuration, a relatively low vehicle speed is given to a driver who is still paralyzed at a feeling of speed or acceleration at the time of exiting from a high-speed running state and shifting to a low-speed running state. Since the alarm device is activated by, the driver can be given an alarm that corrects the driving feeling or acceleration feeling of the driver who is paralyzed by high-speed driving. In a preferred embodiment of the present invention, a vehicle speed warning device includes an infrared detecting means which is sensitive to infrared rays projected from an infrared detector arranged at an entrance gate of a highway, and a window glass for opening and closing a driver's seat. Further comprising a window opening / closing detecting means for detecting whether or not the high speed traveling detecting means determines an entry into an expressway based on the detection results of the vehicle speed detecting means and the infrared detecting means, and the low speed traveling detecting means is Escape from the expressway is determined based on the detection results of the vehicle speed detection means and the window opening / closing detection means.

In another preferred embodiment of the present invention, a vehicle speed alarm device detects a ticket insertion / extraction detecting unit provided in a ticket holder for holding a high speed ticket and an opening / closing state of a windshield in a driver's seat. The vehicle further comprises window opening / closing detection means, the high-speed traveling detection means determines entry of an expressway based on the detection results of the vehicle speed detection means and the ticket insertion / extraction detection means, and the low-speed traveling detection means is configured to detect the ticket insertion / extraction. Escape from the expressway is determined based on the detection results of the detection means and the window opening / closing detection means.

According to such a speed warning device, a warning can be issued to the driver in order to correct the paralysis of the driving feeling or acceleration feeling of the driver that occurs when the driver exits the highway. According to a preferred embodiment of the present invention, the alarm start speed changing means of the speed alarm device includes a reduction time detecting means for detecting a time during which the alarm start speed is reduced, and a reduction time detecting means for detecting the time. And an alarm start speed restoring means for canceling the reduction of the alarm start speed when the predetermined time exceeds a predetermined time.

According to such a speed warning device, the speed warning device can issue a comparatively low speed warning for a predetermined time after shifting from the high speed running to the low speed running, and after the predetermined time has passed, the normal warning is issued. The alarm depending on the starting speed can be automatically returned. According to a further preferred embodiment of the present invention, the alarm start speed changing means of the speed alarm device is an alarm time detecting means for detecting an alarm time issued at a reduced alarm start speed, and the alarm time detecting means. And a cancellation timing delay means for delaying the timing for canceling the reduction of the alarm start speed according to the time detected by the means.

According to such a speed warning device, despite a repeated warning, a driver at a low speed for a relatively long time can be warned to a driver who is still unable to eliminate the paralysis of feeling of speed or acceleration. You can

【Example】

 Hereinafter, preferred embodiments of the present invention will be described in detail with reference to the accompanying drawings. 1 is a schematic configuration diagram of a vehicle speed warning device according to a first embodiment of the present invention, and FIGS. 2 and 3 are flow charts showing a control routine executed by a control unit shown in FIG. is there.

The vehicle speed warning device of this example includes a controller 1 that constitutes a transmitter and an alarm device 5 that constitutes an alarm unit. The controller 1 includes a control unit 11 including a microcomputer and a drive unit 12 that activates an alarm device. The control unit 11 is connected to the vehicle speed sensor 3, the infrared detection sensor 4, and the window opening / closing detection sensor 5, and the detection results Vs, Us, and Ws of these sensors 3, 4, and 5 are input to the control unit 11, respectively. The control unit 11 is also connected to the engine control unit (ECU) 6, and an engine operation signal Es for instructing the operation / non-operation of the engine is input from the engine control unit ECU to the control unit 11.

The alarm device 2 is composed of, for example, a buzzer, a chime, and / or a lamp, and is continuously or intermittently operated by the drive unit 12 in the controller 1. The vehicle speed sensor 3 may be constituted by a vehicle speed sensor having a conventional structure for detecting the vehicle speed. The window open / close detector 5 is configured to detect an operation amount of a power window device arranged on a driver's seat window, for example, an operation amount of an opening / closing operation switch. As another means, the window opening / closing detector 5 may be configured by a contact type switch which is disposed on the upper edge of the window frame and can contact the upper end of the window glass.

Further, the infrared detection sensor 4 is for detecting entry into an expressway by passing through an entrance gate. An infrared detector for detecting passage of a vehicle is generally arranged at the entrance gate of a highway, and the infrared detection sensor 5 is composed of a light receiver that is sensitive to infrared rays projected from the infrared detector. It Most of the infrared detectors are arranged so as to project the infrared beam on the side surface of the vehicle passing through the entrance gate, so the infrared detection sensor 4 is arranged, for example, at a corner of the front bumper.

Next, a control routine executed by the controller 11 of the controller 1 will be described. 2 and 3 are flow charts showing a control routine for controlling the operation of the alarm device 2. The control unit 11 of the controller 1 reads the detection results of the vehicle speed sensor 3, the infrared detection sensor 4, and the window opening / closing detection sensor 5, that is, the vehicle speed Vs, and the infrared-sensitive and window opening / closing instruction signals Us and Ws, respectively (S1). ), When the vehicle speed Vs is a predetermined value α, for example, 100 km / h or more, the drive unit 12 activates the alarm device 2 (S2, S3). Therefore, when the vehicle speed Vs exceeds the predetermined value α during traveling, the alarm device 2 gives an alarm to the driver.

The control unit 11 starts counting the timer A when the infrared sensitive instruction signal Us instructs the reception of infrared rays (S4, S5). The control unit 11 further determines that the vehicle shifts to the steady running at the predetermined value β, for example, the vehicle speed Vs of 80 km / h or more before the count value of the timer A reaches the predetermined set time Tmax, for example, 5 minutes (S6). , S7, S10), the entry of the vehicle into the expressway is recognized (flag F = 1 is set, S8), and the timer A is reset to the initial value 0 (S9).

On the other hand, when the infrared detection sensor 4 is not sensitive to infrared rays (S4), or the vehicle does not shift to the steady running at the vehicle speed Vs of the predetermined value β or more even though the timer A reaches the set time. (S6, S7, S10), the control unit 11 does not recognize the entry of the expressway (flag F = initial value 0 is held). Therefore, when a vehicle is traveling on a general road without passing through an entrance gate of a highway, or when the infrared detection sensor 4 is traveling on a general road, equipment such as a building, for example, an infrared sensor for an automatic door, etc. If the vehicle is sensitive to the red line emitted from, the entry into the expressway is not authorized, and it is considered that the vehicle is still traveling on the open road (flag F = 0).

As shown in FIG. 3, when the control unit 11 recognizes the entry into the expressway (flag F = 1), it determines whether the exit condition of the expressway is satisfied. That is, the control unit 11 stops the vehicle (vehicle speed Vs = 0), the instruction signal Ws for opening and closing the window instructs the opening of the window, and the engine operation signal Es from the engine control unit ECU instructs the operation of the engine. At that time (S12, S13, S14), it is determined that the vehicle has escaped from the highway. It should be noted that such exit conditions are set on the assumption that the driver generally performs an operation when a vehicle enters the exit gate of a highway. When the engine operation signal Es indicates that the engine is not operating (S14), it is considered that the vehicle has entered the parking area or service area of the highway. Do not certify the escape of.

When the escape condition is satisfied (S12, S13, S14), the control unit 11 starts counting the timer B (S15). When the count value of the timer B reaches a predetermined value γ, for example, a vehicle speed Vs of 60 km / h or more before the count value of the timer B reaches a predetermined set time Tmax, for example, 10 minutes (S16), The alarm unit 2 is operated by the drive unit 12 (S17). When the timer B reaches the predetermined set time Tmax (S16), the control unit 11 resets the timer B to the initial value 0 (S19) and certifies the complete escape from the expressway (flag F = initial value 0). Set to S20). Thus, the warning start speed of the speed warning device is transiently reduced to a predetermined value γ = 60 km / h when exiting the highway (S16, S17), and when the predetermined time Tmax elapses after exiting the highway, the above predetermined value is reached. Return to α = 100 km / h (Fig. 2, S2, S3).

When the escape conditions for the expressway (S12, S13, S14) are not satisfied, the control unit 11 determines that the vehicle is still traveling on the expressway (flag F = 1) and starts the alarm. The speed is maintained at a predetermined value α (100 km / h) without being reduced to the speed γ (60 km / h) (FIG. 2, S2, S3). Next, a vehicle speed alarm device according to a second embodiment of the present invention will be described.

FIG. 4 is a schematic configuration diagram of a vehicle speed warning device according to a second embodiment of the present invention, and FIGS. 5 and 6 are a sectional view and a perspective view of a ticket holder. 7 and 8 are flowcharts showing a control routine executed by the control unit shown in FIG. In each figure, the same or equivalent parts or steps as those in the first embodiment are designated by the same reference numerals.

As shown in FIG. 4, in the vehicle speed alarm device of this example, a ticket insertion / extraction signal Ts for instructing insertion / extraction of a high-speed ticket is sent from the ticket holder 7 to the control unit instead of the signal Us from the infrared detection sensor 4. 11 is input. The other overall structure is substantially the same as that of the first embodiment. The ticket holder 7 is a holder for holding a so-called high-speed ticket that records a toll on the highway. The ticket holder 7 is provided at an appropriate position in the vehicle compartment within the reach of the driver, and the driver generally inserts the high speed ticket 18 received at the entrance gate of the highway into the ticket holder 7, At the exit gate of the highway, pull out the high speed ticket 8 from the ticket holder 7.

As shown in FIGS. 5 and 6, the high-speed ticket 18 is a rectangular card having a predetermined width, and the magnetic recording portion 19 is provided on a strip-shaped portion having a constant width formed on the surface. There is. The ticket holder 7 has an insertion slot 20 through which the ticket 18 can pass. In the ticket holder 7, a magnetic head 21 for reading information is arranged along the insertion direction of the ticket 18, and a motor-driven roller 22 is arranged for feeding the ticket.

A trigger switch 23 is provided on the opposite side of the magnetic head 21 to detect the start of ticket insertion and activate the roller 22. Further, guide panels 24 are provided on the upper, lower, left and right sides of the ticket 18 so as to guide the ticket 18 when the ticket 18 is inserted and removed. Further, a limit switch 25 is provided at the tip of the guide panel 24, that is, at the deepest part of the ticket holding structure, and the limit switch 25 detects the insertion of the ticket holder 7. A push button type eject switch 26 is provided below the insertion port 20.

In the control routine of this example, the ticket insertion / extraction signal Ts from the ticket holder 7, the ON / OFF signal of the limit switch 25 and the ON / OFF signal of the eject switch 26 are the instruction signals of the infrared detection sensor 4. Instead of Us, it is used as a criterion for entering a highway (Fig. 5, S4). The ticket insertion / extraction signal Ts is also used as a criterion for exiting the expressway instead of determining whether the vehicle is stopped (vehicle speed Vs = 0) (S12).

As shown in FIG. 7, when the limit switch 25 is turned on and the ticket insertion / extraction signal Ts indicates the insertion of the ticket 18, the control unit 11 starts counting of the timer A (S4, S5). ). When the vehicle speed shifts to the steady running speed of the predetermined value β within the predetermined set time Tmax (S6, S7, S10), the control unit 11 further authorizes the entry into the expressway (flags F = 1, S8). ), And reset the timer A to the initial value (S9).

When the control unit 11 recognizes the entry into the expressway (flag F = 1), it determines whether the exit condition of the expressway is satisfied. That is, the control unit 11 determines the exit of the expressway based on the ticket insertion / extraction signal Ts and the window opening / closing instruction signal Ws, and the ticket 18 is extracted from the ticket holder 7 by operating the eject switch 26. When the glass is opened (S12, S13), it is determined that the vehicle has escaped from the highway. The exit conditions are set on the assumption that the driver generally performs an operation when a vehicle enters the exit gate of a highway, that is, a series of operations in which the ticket 18 is handed to an attendant at the exit gate.

When the vehicle reaches a predetermined value γ or more within a predetermined set time Tmax of the timer B (S15, S16) after the escape condition is satisfied (S12, S13), the control unit 11 drives the drive unit 12 The alarm device 2 is activated according to (S17). Further, the control unit 11 of the present example is configured so that the set time Tmax can be appropriately extended when the alarm device 2 is operated for an excessively long time. The control unit 11 has a timer C that counts the operating time of the alarm device 2. When the alarm device 2 is operated for a predetermined set time T1 of the timer C or more, for example, 3 minutes or more, the set time Tmax of the timer B is set. It is extended by a constant addition time ΔT (S17a, S17b, S17c). Preferably, the addition time ΔT is variably set according to the count time of the timer C. For example, when the alarm device 2 continues for 3 minutes or more, and therefore the count time of the timer C reaches 3 minutes or more, the addition time ΔT is set to 1 minute, and when the alarm device 2 continues for 4 minutes or more, for example. (Timer C count time T ≧ 4 minutes), addition time ΔT is set to 2 minutes, and when the alarm device 2 continues for 5 minutes or more (timer C count time T ≧ 5 minutes), addition The time ΔT is set to 3 minutes. As another means, the control unit 11 may be configured to linearly gradually increase the addition time ΔT as a function of the count time T of the timer C.

As described above, in the above embodiment, the vehicle speed alarm device includes the alarm device 2 and the controller 1 for controlling the operation of the alarm device 2, and the controller 1 indicates the vehicle speed Vs and the infrared ray sensitive instruction. On the basis of the signal Us, or on the vehicle speed Vs and the ticket insertion / extraction signal Ts, an entry judging means for judging entry into the highway, and on the basis of the vehicle speed Vs, the window opening / closing instruction signal Ws and the engine operating signal Es, or the window. Exit determination means for determining exit of the expressway based on the opening / closing instruction signal Ws and the ticket insertion / extraction signal Ts, and an alarm start speed for transiently reducing the alarm start speed immediately after the vehicle exits the expressway. And changing means.

According to such a vehicle speed warning device, the warning device 2 is operated at a relatively low vehicle speed for a driver who is still paralyzed when he or she exits the highway and enters the general road. Activate. Therefore, the speed warning device can issue a warning to the driver in order to correct the driving feeling or acceleration feeling of the driver paralyzed by high-speed driving. In addition, in the above-mentioned embodiment, the entrance determination condition and the exit determination condition, etc. are set in consideration of the present conditions of the entrance gate and the exit gate of the expressway in Japan, but it is not applicable to other types of expressways in other countries. It is possible to appropriately set the above-mentioned determination condition and detection means in accordance with the configuration or the future configuration change of the expressway.

In addition, the speed warning device of the present invention is configured as an alarm device that issues a warning to a driver immediately after a long-time high-speed running state is changed to a low-speed running regardless of whether or not the vehicle is running on a highway. You may. Further, the detection conditions such as the opening / closing operation of the door are combined with the above determination conditions to more specifically determine the entry into the parking area or service area of the expressway.
