In addition, the terms “… unit”, “… unit”, “module”, etc. described in the specification mean a unit that processes at least one function or operation, which may be implemented by hardware or software or a combination of hardware and software. have.

Hereinafter, an embodiment of the present invention will be described with reference to the drawings.

1 is a diagram illustrating a main configuration of a vehicle driving record apparatus according to an embodiment of the present invention, the vehicle driving record apparatus 100 of the present invention is a control unit 110, an acceleration sensor 120, a real time clock ( 130, the recording device 140, the information access device 150, the separation discrimination device 160, the status indicator 170, the power supply device 180, and the auxiliary power supply device 190.

The acceleration sensor 120 is configured to capture the movement of the vehicle and estimate the moving distance of the vehicle.

The acceleration sensor 120 is to use a three-axis acceleration sensor to measure all the acceleration in the up, down, left and back directions. This is to make it easy for the general public to install the vehicle driving recorder 100, without the need to maintain a specific direction when installing.

Acceleration is a change in speed as time progresses. By tracking the change in acceleration over time, you can estimate the current speed and travel distance, and as a sudden change in acceleration (stopping, acceleration, speed bumps, etc.) in a normal driving environment, You can see if it is running.

The real time clock (RTC) 130 is used to determine the days of the week. RTC (130) is normally released so that the vehicle driving recorder 100 can be maintained for one year by setting the day off, current time, its own power supply (battery), it is determined only between 7 am to 10 pm In this case, it is necessary to have a precision enough to maintain an error of + -1 hour for about one year.

The recording device 140 is configured to record information for knowing whether the day is closed. For this purpose, the recording device 140 can be configured as a general memory, and since only the information on a specific day of the week is required, the amount of memory can be made within 53 days (365/7) of the year and for the protection of the driver's privacy rights. Only the minimum information can be stored so that only the distance traveled between 7 am and 10 pm can be stored in kilometers or, if necessary, the entire time of non-working days. This informational data requires only one byte per day and only 53 bytes for one year of information storage.

The information access device 150 may be configured to download information of the vehicle driving recorder 100 to the outside and may be installed therein so as to be accessible only when the case of the equipment is damaged in order to block access to information of the general user.

In addition, although RS-232, USB, and other connection devices are industrial standards, a separate interface component is required to increase manufacturing cost, so it is preferable to configure 3.3V TTL serial communication.

The separation discrimination apparatus 160 is configured to prevent a malicious user from leaving the driving record by separating the vehicle driving record apparatus 100 from the vehicle on a non-working day.

To this end, in Figure 2 and Figure 3 illustrates a departure detection device that is very simple in structure can reduce the manufacturing cost.

2 is a view illustrating a simple outline of a cigar jack adapter as a detachable determination device. The detachable determination device according to the present invention uses one pin of the ground pin of the cigar jack adapter as an earth, and the other pin is attached or detached from the recording device. It is configured to be used as a detecting means for detecting.

Specifically, it is composed of a power connection terminal 162 to which a power supply between + 12V and + 24V is connected, and two pins 164a and 164b for fixed mounting and earth.

3 is an electrical connection diagram of the apparatus of FIG. 2, in which only one of the two pins 164a and 164b is used as the ground (earth), and the other pin is used to determine whether the vehicle driving recorder 100 is mounted to the cigar jack. use.

In this figure, pin 164a will be described as an earth terminal and 164b as a detachable detection terminal.

When attached, the two pins 164a and 164b become a common earth, and the 0V potential is detected by the detachment detecting terminal 164b.

In the case of detachment, the voltage of the auxiliary power is applied to the detachment detecting terminal 164b through the power supply terminal 162 and the resistor 168 so that the detachment can be immediately determined.

That is, when the voltage detected at the detachment detecting terminal 164b is " 0 " V, it can be determined to be mounted and to be detached when it is detected that a predetermined voltage is applied.

Such a detachable determination device is effective because it can be simply configured.

Hereinafter, a detachment determination apparatus of another embodiment will be described with reference to the drawings.

4 is a view illustrating a detachable determination apparatus according to another embodiment. Since the detachable determination apparatus of FIG. 3 determines whether only two earth pins are grounded, the vehicle driving record apparatus 100 is inserted into a separate cigar jack power strip. Next, when the entire multi-tap is removed, there is a disadvantage in that it cannot be accurately determined.

Therefore, the method of determining whether the vehicle driving recorder 100 is attached or detached by measuring the resistance of the vehicle power source connected to the cigar jack adapter.

When the vehicle is turned off while the vehicle driving recorder 100 is mounted, the constant current 261a generated by the auxiliary power supply 261 measures the resistance of the vehicle power terminal 262 of the cigar jack adapter through the backflow prevention diode 263. do.

This is based on the principle that many other devices are connected to the vehicle power source to have a resistive and capacitive load 265, and to show a continuously changing resistance value.

By measuring the voltage of the vehicle power terminal 262 of the cigar jack adapter by the AD converter 267, it is possible to determine that the vehicle driving record apparatus 100 is mounted.

In addition, when the vehicle driving record apparatus 100 or the power strip having the recording apparatus attached thereto is detached from the vehicle, the resistance becomes infinity so that the detachment can be determined.

That is, the resistance is measured by measuring the voltage of the vehicle power supply terminal 262, but if the measured resistance value is infinite, it is separated. If the resistance value is changed, the vehicle driving recorder 100 is installed. To judge.

At this time, by setting the voltage of the zener diode 268 higher than the measured voltage of the power supply device 180 to prevent the measurement of the resistance value of the power supply of the vehicle driving recorder 100.

The power supply unit 180 stably supplies the power required by the recording device from the vehicle power of + 12V to + 24V of the cigar jack.

Since the vehicle driving recorder 100 should be discriminated from the vehicle, it is preferable to include an auxiliary power supply 190 using a battery or the like to charge the vehicle when the vehicle power is connected.

Status indicators 170 indicate normal operation and error conditions using a two-color LED light. When the normal driving record is no longer possible due to the failure of the vehicle driving recorder 100, or when the recording device is detached and refitted against the purpose of use, such as re-installation, the user may respond properly by exchanging an error. Make sure In case of initial error or power short, red light blinks. After a certain time, red light turns on in error state and green light turns on in normal operation.

The controller 110 controls the vehicle driving recorder 100 of the present invention to operate, and in particular, controls the vehicle driving recorder 100 to be stored in the recording device 140.

For this purpose, the control unit 110 not only determines whether the vehicle power is applied, but also records the driving information of the vehicle in the recording device 140, but in order to minimize the possibility of invasion of the right to privacy, from 7 am to 10 pm on non-working days. It is preferable to add only the moving distance between the units in kilometers to record the driving information.

The above-described determination of whether to apply the vehicle power is to determine whether the recording device 140 is detached or detached when the power is not applied using the auxiliary power supply device 190 when the recording device 140 is unintentionally detached from the vehicle.

The control unit 110, the acceleration sensor 120, the RTC 130, the recording device 140, the information connection device 150, the separation discrimination device 160, the status indicator 170, the power supply device 180 and The auxiliary power supply 190 is configured to be assembled to the assembly module of the cigar jack adapter shape so that all components are assembled to the body portion of the cigar jack adapter.

And such an assembly module can be embedded in a vehicle black box, navigation, high pass and these fusion devices.

In addition, referring to the configuration of the cigar jack adapter assembled vehicle driving apparatus of the present invention of Figure 7, the cigar jack-shaped vehicle operating apparatus of the present invention is electrically connected to mount the other cigar jack at its rear end (168) Equipped with), so that other devices using the cigar jack can be connected for convenience of use.

A vehicle driving recording method of the present invention using such a configuration will be described with reference to the drawings.

FIG. 5 is a flowchart illustrating a vehicle driving method of the present invention. The vehicle driving recording method of the present invention is configured to calculate a driving distance for each time zone at a specific time zone of a set non-working day and to record the driving distance.

As shown, the control unit 110 first determines whether it corresponds to the set holiday days using the RTC (130) (S310).

If it corresponds to the non-working day set in step S310, it is determined whether the set time (S312).

In step S312, if the non-working day is set in step S310, all the driving records of the day may be recorded and stored, but it is determined whether the time is between 7 am and 10 pm to prevent invasion of privacy. Therefore, it is a matter of course that the step S312 can be selected by the enemy as needed.

When it is determined that the time is set in step S312, the control unit 110 calculates the movement distance detected by the acceleration sensor 120 for each time zone (S314).

In detail, the acceleration detected by the acceleration sensor 120 represents a change in speed according to time progress, and the current speed and moving distance can be estimated by tracking the change in acceleration over time, and a sudden change in acceleration in a normal driving environment ( Stop, acceleration, speed bumps, etc.)

In the present invention, by adding only the distance traveled in units of kilometers to record the driving information to reduce the pressure of monitoring.

In step S316, the moving distance of the non-working day is calculated for each time zone, and it is determined whether or not the set time has elapsed (S316). If it is determined that the distance of the day of the week to record to the recording device 140.

In the exemplary embodiment of the present invention, the moving distance is calculated first, and then the driving distance is recorded when the set time elapses. However, the moving distance calculated within the set time can be recorded for each time zone.

Since the vehicle driving record apparatus 100 is a simple structure, which is attached to or detached from a normal cigar jack, it is also very important to determine whether the vehicle is detached or not because such a record item cannot be recorded when it is forcibly separated.

Therefore, it is necessary to separately manage the detachment time using a separate detachment determination device.

Hereinafter, with reference to the flowchart for demonstrating the operation | movement of the attachment / detachment determination apparatus of FIG.

The controller 110 determines whether the vehicle power is applied (S331).

When it is determined in step S331 that the vehicle power is not applied, the auxiliary power of the auxiliary power supply device 190 is supplied to the vehicle driving recorder 100 (S332).

When the auxiliary power is applied, the control unit 100 measures the vehicle power resistance through the AD converter 267 (S333).

The controller 100 determines whether the resistance value measured by the AD converter 267 is measured to infinity (S334). When the resistance value is measured to infinity, the controller 100 determines that the vehicle driving recorder 100 is separated from the cigar jack of the vehicle. The separated time is recorded in the recording device 140 (S335).

If it is not measured at the infinite resistance value in step S334 and repeats the step S333, and after recording the separation time in step S335, the vehicle power resistance is measured again to determine whether the vehicle driving recorder 100 is mounted on the cigar jack (S336) In step S337, it is determined whether the measured resistance value is gradually increased, and when the measured resistance value is not an infinite resistance value, the vehicle driving recorder 100 is determined to be mounted on the cigar jack, and the installation time is recorded. 140 to record (S340).

When the resistance value measured in step S337 is measured to infinity, it is determined whether the vehicle power is applied (S338). If it is determined that the vehicle power is not applied, the process is repeated if the vehicle power is applied in step S336. It is determined that the driving recorder 100 is mounted on the cigar jack and records the mounting time (S339).

Whether the vehicle power is applied or not can be measured by digitally inputting the measured analog voltage value by using the preconfigured AD converter 267.

As described above, the detachable determination method of the vehicle driving record apparatus 100 in the vehicle driving record method of the present invention has been described using the configuration according to the second embodiment of FIG.

However, it is a matter of course that the recording apparatus can be attached or detached using the detachment determination device using the cigar jack adapter of FIG. 2.

That is, when the vehicle driving recorder 100 is mounted on the cigar jack, the two pins 164a and 164b become common earths, and the 0V potential is detected by the detachment detecting terminal 164b. Since it is applied to the detachment detecting terminal 164b through the 162 and the resistance 168, it is possible to immediately determine whether the detachment is detected.

That is, when the voltage detected at the detachment detecting terminal 164b is " 0 " V, it can be determined to be mounted and to be detached when it is detected that a predetermined voltage is applied.

The vehicle driving recording method (steps S310 to S340) according to the present invention can be embodied as computer readable codes on a computer readable recording medium. The computer-readable recording medium is a recording device that stores data that can be read by a computer system, and includes a ROM, a RAM, a cache, a hard disk, an optical disk, a floppy disk, and a magnetic tape. In addition, the carrier wave may be implemented in the form of a carrier wave, for example, transmission through the Internet. The computer readable recording medium can also be distributed over network coupled computer systems so that the computer readable code is stored and executed in a distributed fashion.

While the present invention has been particularly shown and described with reference to exemplary embodiments thereof, it is evident that many alternatives, modifications and variations will be apparent to those skilled in the art.
