[2. (Outline of action and effect)
[2-1. (Basic processing)
That is, the replacement date acquisition unit 100 (replacement date acquisition means) acquires the date on which the engine oil was replaced by an input operation from the operation input unit 14 or the remote control light receiving unit 15 and records it as a replacement date in the storage unit 2 ( Exchange date acquisition process). The travel distance acquisition unit 20 (travel distance acquisition means) reads the replacement date from the storage unit 2 and calculates the cumulative travel distance traveled from the replacement date to the present from the electronic control system of the vehicle such as the ECU 17. For example, it is acquired via the vehicle interface unit 10 (travel distance acquisition process).

  Further, the state acquisition unit 30 (state acquisition means) obtains state information including at least the oil temperature from the electronic control system of the vehicle such as the ECU 17 as information related to the state of the engine oil after a predetermined time from the start of the engine. For example, it is acquired via the vehicle interface unit 10 (state acquisition process). This state information includes basic information such as water temperature, oil temperature, hydraulic pressure, and engine speed from the ECU, and further includes additional information for correction such as terrain, season, and weather from the navigation system.

  And the alerting | reporting part 40 (notification means) is based on the acquired said status information, the said cumulative travel distance, and the elapsed days from the said exchange date to the present, when predetermined conditions are satisfied or a reference value is exceeded, When it is determined that the engine oil has deteriorated, the output unit notifies that the engine oil should be replaced (notification process). The determination of engine oil deterioration is actually a process performed by the CPU in accordance with a program, and there is no practical difference or meaning between the main body of the state acquisition unit 30 and the notification unit 40. This point may be considered as any.

  As mentioned above, the deterioration of engine oil takes into account not only the uniform travel distance and period of use, but also changes in oil temperature and other conditions, as well as state information such as vehicle environment. By notifying the user of the replacement time after confirmation, oil replacement at a truly appropriate time is realized. In addition to reducing the number of replacements and reducing the economic burden, maintenance costs are reduced by maintaining engine performance and fuel efficiency is reduced. It is possible to improve and protect the environment.

[2-2. (Status information acquisition timing)
The state acquisition unit 30 acquires each item of the state information at a predetermined time interval (for example, every 30 seconds) during a predetermined time (for example, 30 minutes) after the engine is started. As described above, the state information is acquired every time based on a predetermined time such as 30 minutes and 30 seconds after the engine is started so that the engine oil is deteriorated while the processing load is limited. Changes over time can be detected with high accuracy.

[2-3. (Judgment based on standard information)
In addition, the state acquisition unit 30 includes a reference storage unit 32 and a comparison unit 34. Among these, the reference storage unit 32 (reference storage unit) is a limit value for each item that serves as a criterion for determining deterioration of engine oil performance. Etc. is stored (reference storage process). The comparison unit 34 (comparison means) determines deterioration by comparing the state information of the engine oil that is currently in use with the reference information (comparison process). As described above, by using the reference information stored in advance, it is possible to easily realize objective determination.

[2-4. (Acquire attribute information)
The replacement date acquisition unit 100 includes an attribute acquisition unit 101. The attribute acquisition unit 101 (attribute acquisition unit) acquires attribute information of the replaced engine oil from the operation input unit 14 or the remote control light receiving unit 15, and stores the attribute information. 2 (attribute acquisition process). In this way, not only the date of oil replacement but also the input of attributes such as the type of oil that has been replaced is received and stored, so that it can be reflected in the determination of deterioration.

[2-5. (Use of attribute information)
Further, the comparison unit 34 includes a correction unit 36, and the correction unit 36 (correction unit) stores at least one of the state information acquired for the engine oil being used or the reference information serving as a determination reference. Correction is performed based on the attribute information (correction process). As described above, by correcting the reference information used in the determination and the current state information based on the attribute information of the oil, it is possible to make a highly accurate determination suitable for the specific type and performance of the individual oil.

[2-6. Use of additional information)
The correction unit 36 includes an outside air temperature acquisition unit 37, a vehicle environment survey unit 38, and an electrical component usage survey unit 39. Among these, the outside air temperature acquisition unit 37 (outside air temperature acquisition means) acquires the outside air temperature from the electronic control system of the vehicle such as an ECU or other sensors to make the correction basis (outside air temperature acquisition process). In this way, the determination accuracy can be further improved by reflecting the outside air temperature that has a particularly important influence on the determination of the performance and deterioration of the oil in the determination.

  In addition, the vehicle environment investigation unit 38 (vehicle environment information acquisition unit) is not shown in all figures, but is prepared in advance, such as a date / time timer unit, information reception unit such as the VICS reception unit 11 and the GPS unit 7, not shown. Based on the road map data for navigation, at least one of the barometer, hygrometer, or vehicle interface unit 10, what season is now, what kind of weather is, what is the topography of the current location where the vehicle is located The information about the surrounding environment including at least one of the information is acquired to be the basis of the correction (vehicle environment information acquisition process). As described above, by acquiring and reflecting information on the surrounding environment such as season, weather, terrain such as gradient and altitude, it is possible to further improve the determination accuracy according to the individual specific environment.

  Also, the electrical component usage survey unit 39 (electrical appliance usage status acquisition means) determines how much of the on-vehicle electrical appliances such as an air conditioner has been used for a predetermined time from the start of the engine and the electronic components of the vehicle such as the ECU 17. Obtained from the control system to serve as the basis for the correction (electric product usage status obtaining process). In this way, by acquiring and reflecting the usage status of the electrical components that will ultimately become the engine load, the determination accuracy can be further improved according to the specific usage of the vehicle.

[2-7. Notification of judgment results)
Then, the comparison unit 34 determines that the engine oil should be replaced when it is determined that the engine oil has deteriorated as a result of the determination reflecting the correction based on the above information by the correction unit 36. When the notification is made and it is determined that the performance of the engine oil is not inferior, the notification unit 40 is controlled so as not to notify that the engine oil should be replaced.

  As described above, according to the result of the determination of deterioration of the engine oil reflecting the correction based on the individual specific elements, the replacement time is immediately notified to the user, so that the actual time is not an early or late notification. It is possible to reliably provide information on oil changes in accordance with usage conditions.

[3. Example of processing procedure)
The processing procedure combining the above features is illustrated in the flowchart of FIG. In this procedure, first, it is confirmed whether or not a limit value, which is reference information used for determining deterioration, has already been input (step 10). If there is no input, limit values such as water temperature, maximum oil temperature, oil pressure, etc. For example, from the setting input unit 18 (step 20). For those who do not know in detail, a default option that can be easily set for the input of the viscosity of the oil used may be prepared. The limit value input in this way can be reset when the oil is changed.

  Subsequently, the state acquisition unit 30 obtains state information used for determination of deterioration (step 30). Here, the measured value of each item constituting the basic information included in the state information is used as oil after the previous replacement. The period, water temperature, oil temperature, oil pressure, and engine speed are acquired from the ECU 17 and temporarily recorded in the storage unit 2.

  Next, a preset limit value is read from the reference storage unit 32 (step 40), and each measured value for each item of the basic information at the present time is read from the storage unit 2 (step 50) and compared with the limit value ( Step 60), if each measured value does not exceed the corresponding limit value, the process ends.

  If any measured value exceeds the corresponding limit value, or some set of measured values does or does not meet the composite condition for each limit value (step 60), a more rigorous second stage As a process of (5), the state acquisition unit 30 obtains additional information regarding an element that affects the engine, such as a load, as the remaining part of the state information (step 70).

  Here again, among the information items that make up the additional information, examples of what is obtained from the ECU include the outside air temperature, the usage status of predetermined equipment (for example, the use of electrical equipment such as air conditioners and headlights, etc.) Examples of what you get from the navigation system include season, weather, topographical information about your current location, etc. Based on these additional information, you can determine the legitimacy (whether it is a valid measurement that can be compared), Correction is performed (step 80).

  In the navigation system, the season can be determined based on, for example, a date determined from a built-in clock. The weather can be determined from distribution information such as a hygrometer, rainwater sensor, and VICS, for example. Further, the terrain information can be obtained from, for example, a gradient included in the road map data.

  That is, as a result of the determination, if an effective measurement value that can be compared has been acquired, the validity of the measurement value is determined based on these, or the measurement value is corrected (step 80), Again, it is compared with the limit value, and if it still exceeds the limit value (step 90), the oil is informed if it has deteriorated (step 100).

[4. (Judgment based on graph)
It is desirable to determine the deterioration of the engine oil as described above by using a combination of presence / absence of exceeding a limit value at a predetermined time point and a graph such as a temperature rise curve such as a water temperature or an oil temperature. For example, immediately after the engine is started, the water temperature and oil temperature are low, and the oil pressure and engine speed are high. And

  Regarding the reference information to be compared, the date, the distance traveled at the time of replacement, and the viscosity of the replaced oil are input at the time of oil replacement. At this time, a limit value associated with the viscosity of the oil and a temperature rise graph are stored in advance as a reference prototype, and this prototype is corrected by the oil viscosity input by the user as described above. Determine the limit value and temperature rise graph. Thus, each temperature rise graph of the water temperature and the oil temperature associated with the oil viscosity is referred to as a “reference graph”.

  In addition, every time after the engine is started, in order to obtain a graph that is a measurement value of state information (referred to as “actual graph”), the ECU starts acquiring the water temperature and the oil temperature every 30 seconds and continues this for 30 minutes. The obtained actual state graph is stored in the storage unit.

  Then, after a predetermined time has elapsed since the engine was started (for example, 30 minutes later), the water temperature, oil temperature, and oil pressure at that time are acquired by the ECU, and from the travel distance when the oil replacement date recorded in the navigation system is replaced. The measured value calculated from the number of days to date and the distance traveled is compared with the limit value associated with the viscosity of the oil.

  As a result, if the measured value does not exceed the limit value, the oil is not deteriorated, so the process is terminated. If the measured value exceeds the limit value, the ECU reads the stored actual graph. . In addition to the original water temperature and oil temperature, this graph shows the oil pressure, the outside air temperature at the time of deterioration judgment, and the status of use of electrical products such as air conditioners installed in the car (for example, how much use within 30 minutes from the start of the engine) It may be acquired while correcting it by reflecting the season obtained from the navigation, the weather, topographical information of the current location, and the like.

  Then, for each of the water temperature and the hot water temperature, the above-mentioned actual graph is compared with the above-mentioned reference graph, and if any actual graph does not exceed the corresponding reference graph, the processing is terminated because the engine oil has not deteriorated. However, if any of the actual graphs exceeds the corresponding reference graph, the engine oil has deteriorated, so that effect is notified.

  When comparing the presence / absence of excess between graphs, for example, the comparison criteria such as the ratio of the width and area of the excess portion of the graph and the relative difference of the inclination angle at the intersection and excess portion of the graph may be freely determined.
