Description

BACKGROUND OF THE INVENTION 1. Field of the Invention [0001] The present invention relates to a system and method for informing replacement timing of a consumable item,

BACKGROUND OF THE INVENTION 1. Field of the Invention [0001] The present invention relates to a consumable item management technique, and more particularly, to an apparatus and method for indicating a replacement time of a consumable item indicating a replacement remaining time or a replacement residual distance of each consumable item in consideration of the contribution of each harsh situation.

 Consumables mounted on a vehicle or a mechanical device, such as oil filters, spark plugs, various oils, etc., can be improved in an appropriate manner at an appropriate time to improve the durability, running stability, .

Generally, the vehicle manufacturer provides a manual when a consumable is replaced, and the user records and manages the replacement time of each consumable item by using memo means such as a charger.

Fig. 7 is a diagram showing an example of maintenance items to be managed on a vehicle and an example of replacement timing of the items. Fig. It should be understood that the maintenance target item shown in Fig. 7 shows only a part of the target item described on the manual.

As shown in Fig. 7, examples of maintenance items include engine oil, an oil filter, an air cleaner filter, an ignition plug, a timing belt, a brake disk, and a pad. The replacement period of the item to be maintained is determined according to two conditions (i.e., a harsh condition and a normal condition). For example, in the case of vehicle A, the engine oil and oil filter should be replaced every 15,000 km or once a year under normal conditions, while the engine oil and oil filter should be replaced every 7,500 km or every six months under harsh conditions. In the case of vehicle B, the air cleaner filter should be replaced every 40,000 km under normal conditions, while under severe conditions, it should be replaced when performance deteriorates during frequent inspection and inspection.

Incidentally, as shown in Fig. 7, the replacement timing of items to be maintained on the manual is very ambiguous. That is, the manual does not give exact information on what the normal condition is or what the severe condition is. Accordingly, the consumer has periodically replaced the consumables of the vehicle according to the replacement timing under the condition of either the harsh condition or the normal condition. Or, whenever a maintenance company recommends replacing a consumable, it replaces the consumable. As a result, the following problems may occur.

(1) When a driver having a driving habit corresponding to a severe condition changes the consumable of the vehicle according to the replacement period under normal conditions, the durability and driving stability of the vehicle are degraded.

(2) When a driver having a driving habit corresponding to a normal condition replaces a consumable of a vehicle according to a replacement period under severe conditions, the consumable is frequently replaced unnecessarily. This resulted in unnecessary costs.

(3) When replacing consumables every time a maintenance company recommends replacing consumables, there was no way to verify whether the replacement recommended by the maintenance company was correct. Therefore, there was a possibility of paying an unnecessary expense.

Thus, due to the ambiguity of the replacement timing in the manual, the consumer can not accurately know the replacement time of the consumables, and therefore the durability, the driving stability, or the satisfaction of the consumer are inevitably lowered.

On the other hand, techniques for automatically confirming the replacement timing of the consumables and notifying the user (e.g., Korean Patent Laid-Open No. 10-1995-0017471 and Korean Patent Laid-open No. 10-2017-0013019) have also been developed.

However, a method of notifying a replacement time of a consumable according to one prior art technique includes calculating a use distance of the consumable based on the distance traveled by the vehicle, subtracting the actual distance of the vehicle from the use distance of the consumable, When the difference between the distance and the actual operating distance becomes zero, it is judged that the time for replacing the consumables has arrived.

Another method of informing the replacement time of the consumables according to the prior art is to input the usage period of the consumable item of the vehicle from the user and to calculate the replacement period of the consumption consumable of the vehicle used before the analysis based on the usage period of the consumables, Estimates the usage distance, calculates the usage distance of the consumable product corrected based on the driving distance of the vehicle, the distance of use of the vehicle consumable item, the analysis period, and the usage period of the vehicle consumable item, The remaining consumption of consumables was calculated.

However, according to the above-described prior arts, it is difficult to know which replacement period is used, among the replacement cycle of the consumables under the severe condition and the replacement cycle of the consumables under the normal condition, The relevant factors were not reflected in the calculation of the remaining consumption of consumables. As a result, the consumer still could not know when to replace the proper consumables.

The matters described in the background section are intended to enhance the understanding of the background of the invention and may include matters not previously known to those skilled in the art.

FIG. 5 is a view showing an example of a predetermined contribution to harsh situations occurring when a vehicle is traveling, FIG. 6 is an example of items to be maintained and their modified replacement periods, and FIG. Fig.

As shown in FIG. 3, a method of notifying the replacement time of the consumable according to the embodiment of the present invention starts when the sensor unit 110 detects data (S400).

When the sensor unit 110 detects data, the data is transmitted to the controller (hereinafter, at least one of the first controller 160, the second controller 220, and the third controller 320, or a combination thereof) do. The controller analyzes the data to determine whether a predefined harsh situation has occurred (S410). FIG. 4 shows an example of sensors for detecting predefined severe situations, predefined proportions of the severe situations, and data for determining whether a corresponding severe situation occurs. For example, whether or not the occurrence of a severe situation such as " repeatedly running a short distance " is determined based on data detected from a vehicle speed sensor, a vehicle body acceleration sensor, a wheel speed sensor, a wheel acceleration sensor, a GPS sensor, and / or an ignition switch . Although FIG. 4 shows ten harsh situations, the number and types of harsh situations are not limited to this. In addition, the types of sensors for detecting data for determining whether a severe situation occurs are not limited to the sensors shown in FIG.

If no harsh conditions have occurred in step S410, the method returns to step S400 and continues to detect data. Otherwise, if it is determined in step S410 that a severe situation has occurred, the method proceeds to step S420.

In step S420, the controller calculates the contribution of the harsh situation. Here, the contribution of the harsh situation means how well the detected data meets the harsh conditions. FIG. 5 shows an example of the contribution condition for calculating the contribution of the harsh situation. Quot; 1-DP " described in the contribution condition means that the contribution corresponds to the one-dimensional parameter, and " 2-DP " means that the contribution corresponds to the two-dimensional parameter. The process of calculating the contribution of the harsh situation will be described in detail as follows.

If a harsh situation occurs, the controller operates a timer or similar device to detect the duration of the severity of the situation or the distance the vehicle traveled during the duration of the severe situation. Here, the duration of the severe condition is defined as the driving time (T _i ) under the severe condition, and the distance traveled by the vehicle during the severe condition is defined as the driving distance ( _Mi ) under the severe condition . Also, the running time or the running distance under such a harsh situation means the time or distance in which the data related to the contribution of the harsh situation traveled in the same state. For example, if the vehicle travels at a first travel distance M ₁ or a first travel time T ₁ at a speed of 170 km / h, increases the speed to a second travel distance M ₂ at a speed of 180 km / If the second travel time T ₂ has been traveled, the controller determines that a severe situation such as " the case where the frequency of high-speed travel is high " At this time, the controller assumes that two harsh situations (first harsh situation and second harsh situation) have occurred, detects the traveling time or the traveling distance under the first harsh situation as M ₁ or T ₁ , The traveling time or the traveling distance is detected as M ₂ or T ₂ .

The controller then determines how well the harsh situation matches the contribution condition. For example, a severe situation such as " when the frequency of high-speed travel is high " corresponds to a one-dimensional parameter (i.e., vehicle speed). In addition, if the vehicle speed is 200 km / h or more, the contribution is 100%, and if the vehicle speed is less than 80 km / h, the contribution condition is predefined as 0%. If the vehicle traveled at a speed of 220 km / h, the contribution would be 100%, and if the vehicle traveled at a speed of 50 km / h, the contribution would be 0%. On the other hand, if the vehicle has traveled at a speed of 170 km / h, the contribution can be calculated by the interpolation method. The interpolation method for calculating the contribution may use at least one of various interpolation methods known in the art. Various interpolation methods such as linear interpolation, curve interpolation, interpolation using a polynomial function, interpolation using a trigonometric function, interpolation using a logarithmic function, and interpolation using an exponential function are well known and will not be described in detail here.

For another example, a severe situation such as " when the running frequency on a rough road is high " corresponds to a two-dimensional parameter (body vibration and slip rate). In addition, the contribution condition of the harsh situation is defined as 100% when the root mean square (rms) is larger than 0.5G and 0% when the body vibration rms is less than 0.2G. Also, the condition of contribution of the severe situation is defined as 100% when the slip ratio is greater than 0.2, and 0% when the slip ratio is less than 0.05. In this case, the contribution of the severe situation of "high running frequency on the rough road" can be calculated as the average of the contribution according to the body vibration rms and the contribution according to the slip rate. On the other hand, the proportion of the contribution according to the body vibration rms and the contribution according to the slip ratio are defined in advance, and the proportion of the contribution according to the body vibration rms and the proportion of the contribution according to the slip ratio are considered, Is high "can be calculated. If the body vibration rms is 0.2 G or more and 0.5 G or less, or the slip ratio is 0.05 or more and 0.2 or less, the contribution can be calculated by an interpolation method.

Referring again to FIG. 3, if the contribution of the harsh situation is calculated in step S420, the controller calculates the degree of severity using the contribution of the harsh situation and the travel distance or travel time under the harsh situation (S430). Here, the degree of severity is an index for indicating how harsh conditions the current running is. Hereinafter, the process of computing severity is described in detail.

The controller calculates a severity S _j for each of the harsh situations that have occurred up to now since the previous replacement of the consumable item and calculates severity S _T according to the individual severity and the specific weight W _j for those severe situations, . The proportion of severity here indicates the degree to which the severity affects severity. For example, referring to FIG. 5, the severity condition of "a short distance repeatedly running" is defined as 1 while the "severe idling time" is defined as 3 have. This means that the severe situation of "when idling is overdone" is three times more severe than the "short distance repeatedly running" situation. Also, the weight can be used not only when each severe situation occurs, but also when the occurrence periods of each severe situations overlap. The weight can be defined in advance through big data analysis. The specific gravity shown in Fig. 5 is only one example, and it is also possible to determine the specific gravity.

J harsh situations in which the distance traveled to the present after the replacement of the consumables is now M, and the occurrence time of the consumables does not overlap with each other since the previous replacement (the first harsh situation, the second harsh situation, ..., situation, ..., j-th harsh conditions) is occurred, and the running distance of the j-th harsh conditions M _j, M _j is if I is divided into two sections, M _j may be calculated by the following equation: .

Here, M _ji is the traveling distance of the i-th section.

If the time of occurrence of each severe situation does not overlap, the individual severity (S _j ) due to the jth severe situation can be calculated by the following equation.

이다. 도 4 및 도 5에 도시된 가혹 상황에 대한 비중은 해당 가혹 상황이 각각의 부품에 미치는 영향이 다른 경우가 있으므로, 각각의 부품에 대하여 각각 다른 비중을 채택할 수 있다. 또한, 중복된 가혹 상황에 대한 개별 가혹도의 비중을 전부 인정하는 경우 Nd=1로 설정할 수 있다. Where W _ji is the specific gravity of the i-th period, C _ji is the contribution of the i-th period, and N _d is the

to be. 4 and FIG. 5 may have a different effect on each component, so that a different weight can be adopted for each component. In addition, Nd = 1 can be set if all the severity of the individual severity of the overlapping severity is all recognized.

In this case, the degree of severity (S _T ) can be calculated by the following equation.

However, some of the harsh situations may overlap in time. That is, the jth severity situation may be caused by overlapping two or more sub severity situations. The individual severity (S _j ) due to the jth severe situation can be calculated by the following equation.

이다. 앞에서 언급한 바와 같이, 중복된 가혹 상황에 대한 개별 가혹도의 비중을 전부 인정하는 경우 Nd=1로 설정할 수 있다. 다른 방법으로, 기여도와 비중을 고려한 것 중에 최대값만을 취하여 중복된 가혹 상황을 대표하는 방법도 있다. 이 경우, 개별 가혹도(S_j)는 S_j=M_j * Max(W_jiC_ji)/M으로 표현된다. Here, W _ji is the weight of the i-th sub-severe situation, M _ji is the driving distance under the i-th sub-severe situation, C _ji is the contribution of the i-th sub-

to be. As mentioned above, Nd = 1 can be set if all of the severity of the individual severity of the redundant harsh situations is all recognized. Alternatively, there is a method to represent the overlapping harsh situations by taking only the maximum value of the contribution and weight. In this case, the individual severity S _j is expressed as S _j = M _j * Max (W _ji C _ji) / M.

On the other hand, if we do not take the weight into consideration when computing severity, the above equations will change as follows.

If the time of occurrence of each severe situation does not overlap, the individual severity (S _j ) due to the jth severe situation can be calculated by the following equation.

Where C _ji is the contribution of the i-th section, and M _ji is the running distance of the i-th section.

In this case, the degree of severity (S _T ) can be calculated by the following equation.

If the occurrence times of some of the harsh situations overlap each other, the individual harshness (S _j ) due to the jth harsh situation can be calculated by the following equation.

이다. 여기서, M_j는 j번째 가혹 상황의 주행 거리이다. 가혹 상황의 중복을 허용하는 경우엔느 Nc=1로 할 수 있으며, 최대값으로 구간의 가혹도를 대표하여 나태내는 경우 [수학식 7]은 S_j=M_j * Max(C_ji)/M으로 된다. Where M _ji is the travel distance under the ith sub-harsh situation, C _ji is the contribution of the ith sub-harsh situation, and N c

to be. Here, M _j is the traveling distance of the j-th severe situation. If the redundancy of the severe situation is allowed, Nc = 1, and if the maximum value is represented as the degree of severity of the interval, Equation (7) can be expressed as S _j = M _j * Max (C _ji ) / M .

In the above, a method of calculating the severity using the mileage is exemplified, but the severity can be calculated in the same manner using the travel time. Also, it should be understood that the method of calculating the degree of severity illustrated above is only one example, and that various changes, modifications, and alterations may be made without departing from the technical scope of the present invention.

Referring again to FIG. 3, if the severity is calculated in step S430, the controller determines whether the severity is greater than the first severity (S440). Here, the first degree of severity can be preset in the severe road corresponding to the severe condition in the manual. The degree of severity corresponding to the severe condition in the manual can be preset through the big data analysis.

If the degree of severity is greater than the first degree of severity, the replacement time T1 or the replacement distance M1 under the severe condition is regarded as the replacement time Tc or the replacement distance Mc (S460). FIG. 6 is a view showing a modification of replacement timing of items to be maintained to use the method according to the embodiment of the present invention. The replacement timing of the maintenance target items shown in Fig. 6 is substantially the same as the replacement timing of the maintenance target items shown in Fig. However, in FIG. 7, when the item to be maintained is indicated as " occasional check ", the item to be replaced or the item to be replaced need to be quantified Has been modified. Further, in the modification of the replacement period, the ratio of the replacement period under the normal condition to the replacement period under the severe condition (for example, 1/2) is maintained, but the present invention is not limited thereto.

Referring to FIG. 6, if the degree of severity is greater than the first degree of severity in step S440, the replacement time of the air cleaner filter of the vehicle B becomes 20,000 km. As another example, if the degree of severity is greater than the first degree of severity in step S440, the replacement time of the timing belt of the vehicle A is 80,000 km.

If the severity is less than the first severity in step S440, the controller determines whether the severity is less than the second severity (S450). Here, the second degree of severity may be set in advance to a severe road corresponding to a normal condition on the manual. The degree of severity corresponding to the normal condition on the manual can be preset through the big data analysis.

If the degree of severity is smaller than the second severity, the replacement time T2 under the normal condition or the replacement distance M2 is regarded as the replacement time Tc or the replacement distance Mc in step S470. Referring to FIG. 6, if the degree of severity is smaller than the second degree of severity in step S450, the replacement time of the air cleaner filter of the vehicle B becomes 40,000 km. As another example, if the degree of severity is smaller than the second degree of severity in step S450, the replacement time of the timing belt of the vehicle A becomes 0,000 km.

If the degree of severity is equal to or greater than the second severity in step S450, the controller determines the replacement time Tc or the replacement distance Mc according to the severity (S480). The replacement time Tc or the replacement distance Mc depending on the degree of severity is determined based on the replacement time T1 under the harsh condition or the replacement distance M1 and the replacement time T2 under the normal condition or the replacement distance M2, Can be determined by interpolation. For example, the replacement time Tc or the replacement distance Mc according to severity (S _T ) can be determined by the following equation.

For example, if the degree of severity corresponding to the normal condition is 70%, the degree of severity corresponding to the severe condition is 30%, and the degree of severity calculated in the step S430 is 50%, the timing belt replacement The time is 120,000 km according to the linear interpolation method.

Herein, the linear interpolation method is exemplified by the interpolation method of interpolating the replacement time or the replacement distance according to severity, but the present invention is not limited thereto. The interpolation method interpolating the replacement time or the replacement distance according to severity may use at least one of various interpolation methods known as necessary. Various interpolation methods such as linear interpolation, curve interpolation, interpolation using a polynomial function, interpolation using a trigonometric function, interpolation using a logarithmic function, and interpolation using an exponential function are well known and will not be described in detail here.

If the replacement time Tc or the replacement distance Mc has been determined in steps S460 through S480, the controller determines whether the replacement time Tc or the replacement distance Mc and the running time T The replacement residual time Tr or the replacement residual distance Mr is calculated using the distance M (S490). For example, the controller can calculate the replacement remaining time Tr by subtracting the running time T from the previous replacement to the present consumption time at the replacement time Tc, or calculate the replacement remaining time Tr at the replacement distance Mc It is possible to calculate the replacement residual distance Mr by subtracting the running distance M of the vehicle.

For example, if a vehicle having a replacement timing of 120,000 km of the timing belt of the vehicle A according to the degree of severity traveled 110,000 km after the replacement of the previous timing belt, the replacement remained distance would be 10,000 km.

Then, the controller notifies the replacement time of the consumables (S500). For example, at least one of the first display 180, the second display 260, and the third display 340 may display a replacement remaining time or a replacement remaining distance, or may display a replacement remaining time or replacement The remaining distance can be displayed. Further, if the replacement residence time Tr is smaller than the threshold time or the replacement residence distance Mr is smaller than the critical distance, the controller can light the warning light on the in-vehicle first display 180 or reproduce the warning sound. Furthermore, if the replacement remaining time Tr is smaller than the threshold time or the replacement remaining distance Mr is smaller than the threshold distance, the controller can display the push notification window on the registered portable device 300 or the home page.

On the other hand, if the consumable is replaced, the controller resets all mileage or travel time associated with the embodiment of the present invention. Through this, the travel time or travel distance after the previous replacement of the consumables and the travel distance or travel time under the corresponding severe condition after the previous replacement of the consumables can be accumulated again.

While the present invention has been described in connection with what is presently considered to be practical exemplary embodiments, it is to be understood that the invention is not limited to the disclosed embodiments, but, on the contrary, And all changes to the scope that are deemed to be valid.
