METHOD FOR CORRECTING VIBRATION BY LIGHTING CONTROL WIRING OF CLUSTER AND AVN AND LIGHTING VIBARATION CORRECTION DEVICE USING THE SAME}

The present invention relates to a method for compensating for shaking by lighting control wiring of a cluster and an AVN, and an apparatus for compensating for lighting shaking using the same. The present invention relates to a method for compensating a shake by a lighting control connection of a cluster and an AVN for preventing AVN lighting shake, and a lighting shake correction device using the same.

BACKGROUND ART Generally, a dashboard of a vehicle is equipped with a cluster having a function of displaying driving and operating states of the vehicle and lighting states so that a driver can know them. That is, the cluster has instruments that display vehicle operating speed, rotational speed (rpm), fuel amount, etc., lights (headlights, fog lights, reversing lights, interior lights, instrument lights), traffic lights (turn indicators, brake lights), warning lights ( A lighting device for displaying lighting conditions of a hydraulic light, a charging light, a fuel light, a brake oil light, etc.) and an indicator light (tail light, parking light, number light, vehicle position light). The lighting device of the cluster receives the lighting control switch and adjusts the brightness of the lighting.

On the other hand, AVN is a multimedia system for vehicles in which an audio system, a video system, and a navigation system are integrated into one unit. The development of such an AVN provides convenience to users in manipulating various multimedia devices and enables efficient utilization of the interior space of a vehicle. Similarly, the lighting device of AVN adjusts the brightness of lighting.

These clusters and AVNs can be interconnected to control lighting identically to each other. That is, the cluster and the AVN reflect the same light level to the AVN through rheostat control through the CAN connection.

However, when the cluster and the AVN are configured by lighting control wiring, a level value distribution is changed due to the influence of vehicle noise, causing a flickering phenomenon in the AVN lighting.

In this case, when the cluster and the AVN are mutually connected to each other through a lighting control connection, a technique for correcting lighting shaking needs to be proposed.

1 is a diagram showing a cluster and AVN configuration of the present invention.

As shown in FIG. 1, the cluster 10 and the AVN 20 are connected through wiring for the same lighting control.

The AVN 20 includes a CPU 21 that controls each of the audio system, video system, and navigation system, a microcomputer 22 that controls lighting in the same way as the cluster 10 and the AVN 20, and vibration caused by lighting control wiring. It includes an illumination stabilization device 23 for correcting.

The lighting stabilization device 23 is a separate component from the CPU 21 or the microcomputer 22, and is added to the wiring of the cluster 10 and the AVN 20 without replacing the CPU 21 or the microcomputer 22 to illuminate tremors can be corrected.

Here, the lighting shake correction device 23 may include at least one processor and a memory for storing computer readable instructions. Computer readable instructions are executed by at least one processor.

2 is a diagram illustrating an embodiment of cluster specifications and AVN measurement values.

Looking at the cluster specifications (ILL-spec) and AVN measurement values for each lighting stage in FIG. 2, the lighting stages range from stage 1 to stage 21, and the stages of occurrence of light shaking represent stages 3, 6, 7, and 17.

3 is a diagram for a shake correction method by lighting control wiring of a cluster and an AVN according to an embodiment of the present invention.

First, when the vehicle is started, the lighting shake compensating device 23 checks cluster specifications for each lighting level (S101). That is, the lighting stabilization device 23 checks the cluster specifications of each step from step 1 to step 21 as shown in FIG. 2 .

Thereafter, the lighting shake compensating device 23 checks AVN measurement values for each lighting level (S102). Here, the level value distribution of the AVN measurement value is changed due to the influence of vehicle noise, resulting in a lighting flickering phenomenon.

After that, the illumination stabilization device 23 mutually compares the cluster specification for each illumination level and the AVN measurement value (S103).

At this time, the lighting shake correcting device 23 performs AVN measurement value correction (S104) when it is confirmed that shaking occurs in the AVN measurement value (S103). This process is repeated until the lighting shake correcting device 23 confirms that no shake occurs in the AVN measurement value.

Then, when it is confirmed that no shaking occurs in the AVN measurement value (S103), the lighting shake correcting device 23 performs steps S102 to S104 again after a predetermined time to check the AVN measurement value correction result again (S105). . Here, the correction result reconfirmation time (eg, 10 minutes, 20 minutes, 30 minutes, etc.) may be set by the user.

FIG. 4 is a diagram illustrating an AVN measurement value correction process in step S104 of FIG. 3 .

First, when performing AVN measurement value correction, the lighting shake correcting device 23 checks the level of the lighting shake area (S104a). At this time, the lighting shake compensating device 23 selects a lighting shake level step and an adjacent light level step in which the cluster specification is included in the range of AVN measurement values as the light shake area level step.

For example, in FIG. 2 , the level of illumination level in which the cluster specification is included in the range of AVN measurement values is level 3, and the level of adjacent illumination level is level 2 and level 4. The level of the light shaking area is selected as the second, third, and fourth stages.

Thereafter, the lighting shake compensating device 23 corrects the AVN measurement value by applying a correction function to the lighting shake area level step (S104b). Here, the lighting shaking region level step can be represented as shown in Table 1 below, and the correction function for performing the correction of the AVN measurement value can be represented as shown in Table 2 below.

light level step Step (D-1) (D) step (D+1) phase cluster spec A B C AVN measurements A1 to A2 B1 to B2 C1 to C2

correction function Confirm correction (A<B1) PASS OR calibration If correction is required, adjust the B1 value higher than the A value (B＞A2) PASS OR calibration If correction is required, adjust A2 value smaller than B value (B<C1) PASS OR calibration If correction is necessary, adjust C1 value higher than B value (C＞B2) PASS OR calibration If correction is necessary, adjust B2 value smaller than C value

Referring to Tables 1 and 2, cluster specifications at a specific illumination level step are compared in magnitude with minimum or maximum values of AVN measurement values at adjacent illumination level steps.

The cluster specification satisfies a correction function that is greater than the maximum value of the AVN measurement value of the illumination level stage preceding one stage and less than the minimum value of the AVN measurement value of the illumination level stage after the one stage.

The illumination stabilization device 23 adjusts the maximum value of the AVN measurement value to be small when the cluster specification is not greater than the maximum value of the AVN measurement value in the previous illumination level stage. Further, the lighting shake compensating device 23 adjusts the minimum value of the AVN measurement value to a large level when the cluster specification is not smaller than the minimum value of the AVN measurement value in the illumination level stage after the first stage.

Specifically, the size of the cluster specification (A) in step (D-1) is compared with the minimum AVN measurement value (B1) in step (D), which is an adjacent illumination level step. The cluster specification (B) in step (D) compares the size with the maximum AVN measured value (A2) in the adjacent lighting level step (D-1) and the minimum AVN measured value (C1) in the (D+1) step. will do The size of the cluster specification (C) at the step (D+1) is compared with the maximum AVN measurement value (B2) at the step (D), which is an adjacent lighting level.

That is, when comparing the sizes of AVN measurement values of adjacent lighting level stages, the cluster specification compares the maximum AVN measurement value of the previous lighting level stage and the minimum AVN measurement value of the lighting level stage after the next stage. size comparison.

Accordingly, the lighting shake compensating device 23 may perform correction of AVN measurement values as follows by applying a correction function to the second, third, and fourth steps of the lighting shake area level.

The light shaking region level step can be represented as shown in Table 3 below.

light level step Step 2 Step 3 Step 4 ILL-spec 3.6(A) 4.3(B) 5.2(C) AVN measurements 3.41 (A1) to 3.47 (A2) 3.51 (B1) to 5.21 (B2) 5.14 (C1) to 5.21 (C2)

Then, the lighting shake correcting device 23 applies the correction function as shown in Table 4 below to correct the AVN measurement value as follows.

compare Confirm correction (3.6 < 3.51) correction 3.51→3.7 (4.3＞3.47) PASS - (4.3 < 5.14) PASS - (5.2＞5.21) correction 5.21→5.1

On the other hand, if lighting shake is confirmed after reflecting the correction value (S104c), the lighting shake correcting device 23 may perform correction again using a correction function (S104b).

On the other hand, if the lighting shaking is confirmed after reflecting the correction value (S104c), the lighting shake compensating device 23 provides the correction value and performs step S103 of FIG. 3 (S104d).
