Description

  The present invention relates to a vehicle management apparatus, and more particularly to a vehicle management apparatus for urging maintenance to prevent a vehicle failure caused by consumption of consumables such as engine oil as the vehicle is used.

In the vehicle, engine oil, which is one of the consumables, is gradually consumed every time the vehicle is driven, and if the amount of engine oil is low, the engine may be damaged. . For this reason, the maintenance of the engine or the like is necessary for the user (driver or the like) for vehicle management.
As a vehicle management device, for example, Japanese Patent Laid-Open No. 2006-021570 discloses a wear deterioration quality management device and a wear deterioration quality management method for recommending replenishment and replacement of consumables such as engine oil until the next maintenance. ,Proposed.

JP 2006-021570 A

  However, conventionally, merely detecting the amount of engine oil and notifying the necessity of maintenance may cause the user to take a different action from the action that should actually be taken. For example, when engine oil leakage has occurred, the user may determine that the amount of engine oil has been reduced, and say that he / she only needs to refill the engine oil.

  Accordingly, an object of the present invention is to provide a vehicle management apparatus capable of notifying the user of the necessity of maintenance by another treatment even after the user takes an erroneous treatment during vehicle maintenance. .

  The present invention calculates a remaining amount detecting means for detecting a remaining amount of consumables and a degree of reduction of the consumables in a vehicle management apparatus that facilitates maintenance of consumables that are consumed over time or usage of the vehicle. An electronic control unit having a reduction degree calculating means for performing the first notification or a second notification different from the first notification, the electronic control unit being calculated by the reduction degree calculating means The first notification is made based on the fact that the degree of decrease has fallen below the first determination value, and the second notification has been made based on the fact that the degree of decrease calculated by the reduction degree calculation means has fallen below the second determination value. As described above, the operation of the notification means is controlled.

  Since the present invention performs different notifications according to the degree of reduction of the consumables, even when the user takes an incorrect measure during vehicle maintenance, the user may be notified of the need for maintenance by another measure. it can.

FIG. 1 is a control block diagram of the vehicle management apparatus. (Example) FIG. 2 is a schematic plan view of the vehicle. (Example) FIG. 3 is a flowchart of vehicle management. (Example) FIG. 4 is a time chart for vehicle management. (Example)

  The present invention realizes the purpose of notifying the user of the necessity of maintenance by another treatment even when the user takes an erroneous measure during vehicle maintenance by performing different notifications according to the degree of reduction of consumables. To do.

1 to 3 show an embodiment of the present invention.
As shown in FIG. 2, the vehicle 1 is equipped with an engine 3 and a transmission 4 as a power torrent 2 for moving the vehicle 1, and a vehicle management device 5 for managing the state of the vehicle 1. . The vehicle management device 5 promotes maintenance of consumables that are consumed with the use of the vehicle 1 and over time. Examples of consumables include engine oil and engine coolant (coolant).

As shown in FIG. 1, the vehicle management device 5 includes an electronic control unit 6, a plurality of controllers, for example, first to third controllers 7 </ b> A to 7 </ b> C, and a plurality of sensors, for example, first to fourth. Sensors 8 </ b> A to 8 </ b> D and notification means (such as a monitor) 9 are provided. The electronic control unit 6 is connected to the first to third controllers 7A to 7C and the first to fourth sensors 8A to 8D on the input side, and to the notification means 9 on the output side.
The electronic control unit 6 operates the notification means 9 based on various information of the vehicle 1 from the first to third controllers 7A to 7C and the first to fourth sensors 8A to 8D to perform maintenance of consumables by the user (driving For example).
The first to third controllers 7A to 7C include various controllers such as an engine controller (ECM) and a transmission controller (TCM).
The first to fourth sensors 8A to 8D are various sensors that detect the amount of liquid (remaining amount) of engine oil, engine cooling water, and the like.
The notification means 9 includes a monitor and performs predetermined notification to the user.

The electronic control unit 6 includes a remaining amount detection unit 10, a decrease degree calculation unit 11, a notification determination unit 12, a notification execution unit 13, and a storage unit 14.
The remaining amount detection means 10 detects the remaining amount of consumables.
The reduction degree calculation means 11 calculates a reduction degree (change amount) that is a reduction degree of the consumables.
The notification determination unit 12 presets a first determination value and a second determination value. In this case, the notification determination unit 12 sets the first determination value to be larger than the second determination value (first determination value> second determination value). The notification determination unit 12 compares the reduction degree (change amount) of the consumables calculated by the reduction degree calculation unit 11 with the first determination value or the second determination value set in advance.
The notification execution means 13 outputs a signal for operating the notification means 9.
The memory | storage means 14 memorize | stores various information, such as various liquid amount and transition (change amount) of a liquid amount.

  The notification means 9 performs the first notification or the second notification different from the first notification. The first notification is a notification that prompts the user of the vehicle 1 to check the vehicle 1. The second notification is a notification that notifies the user of the vehicle 1 that the vehicle 1 is abnormal.

  The electronic control unit 6 operates the notification means 9 to perform the first notification based on the determination that the decrease degree calculated by the decrease degree calculation means 11 is lower than the first determination value. The electronic control unit 6 operates the notification unit 9 to perform the second notification based on the determination that the decrease degree calculated by the decrease degree calculation unit 11 is lower than the second determination value.

Next, the vehicle management of this embodiment will be described along the flowchart of FIG.
As shown in FIG. 3, when the program starts in the electronic control unit 6 (step A01), first, the reduction degree calculation means 11 calculates a reduction degree (change amount) that is a reduction degree of the consumables (step A02). ). The degree of reduction, which is the degree of reduction of consumables, is calculated based on, for example, the remaining amount of consumables calculated by the remaining amount detection means 10.
Then, the notification determination unit 12 determines whether or not the decrease degree calculated by the decrease degree calculation unit 11 is lower than the second determination value (decrease degree <second determination value) (step A03).
If step A03 is YES and the degree of decrease is less than the second determination value, the notification execution means 13 performs a second notification that is a notification that informs the user of the vehicle 1 that the vehicle 1 is abnormal. Thus, the notification means 9 is operated (step A04).
On the other hand, when step A03 is NO and the reduction degree exceeds the second determination value, the notification determination unit 12 determines whether or not the reduction degree is lower than the first determination value (decrease degree <first determination). Value) is determined (step A05).
When step A05 is YES and the degree of decrease is less than the first determination value, the notification executing means 13 performs a first notification that is a notification that prompts the user of the vehicle 1 to check the vehicle 1. The notification means 9 is actuated (step A06).
If step A05 is NO and the degree of decrease exceeds the first determination value, the program is returned after the process of step A04 or after the process of step A06 (step A07).

As a result, in this embodiment, the electronic control unit 6 performs the first notification based on the fact that the reduction degree calculated by the reduction degree calculation means 11 falls below the first determination value. To control the operation. Further, the electronic control unit 6 controls the operation of the notification means 9 so that the second notification is made based on the fact that the decrease degree calculated by the decrease degree calculation means 11 falls below the second determination value. Thereby, even after the user takes an incorrect measure during the maintenance of the vehicle 1, it is possible to notify the user of the necessity of maintenance by another measure.
The first notification is a notification that prompts the user of the vehicle 1 to check the vehicle 1. The second notification is a notification that notifies the user of the vehicle 1 that the vehicle 1 is abnormal. Thereby, a user can be notified of the necessity of the maintenance of the vehicle 1 at an early stage by different notifications.
Further, the first determination value is set larger than the second determination value. Thereby, it is possible to notify the user of the necessity of maintenance of the vehicle 1 at an early stage according to the degree of decrease calculated by the degree-of-decrease calculating means 11.

FIG. 4 shows a time chart for vehicle management according to the present invention.
The electronic control unit 6 receives, for example, a signal (a signal corresponding to “liquid amount”) from any one of the first to fourth sensors 8A to 8D that detects the liquid amount of the engine cooling water. To do. The electronic control unit 6 calculates the change amount (decrease degree) of the engine coolant by the reduction degree calculation means 11 and determines “warning” or “abnormal” by the notification determination means 12 according to the change amount.
In FIG. 4, as a premise, the determination value is a determination value for determining that the engine cooling water is to be replenished. When the amount of the engine cooling water in the cooling water tank is visually confirmed, the “LOW” scale is used. Is the value.
In FIG. 4, when the amount of liquid is decreasing in a predetermined first period M1 from P1 (time t1) to P2 (time t2), the change amount D1 is normal. The electronic control unit 6 assumes that the state of the engine cooling water is “normal”, does not operate the notification means 9 and does not perform notification.
However, when the amount of liquid drastically decreases in the second period M2 shorter than the first period M1 from P2 (time t2) to P3 (time t3) (M1> M2), the change amount D2 is abnormal. And The electronic control unit 6 determines that the state of the engine cooling water has to be “warned” to the user, and operates the notifying means 9 to prompt the user to check the engine cooling water to notify the user of the “warning”. (First notification) is performed.
Thereafter, when the amount of liquid becomes smaller than P3 (time t3) and a change amount D3 that cannot be normally generated, it is determined that an “abnormality” such as breakage or leakage of the cooling water tank has occurred. The electronic control unit 6 operates the notification means 9 to notify the user of “abnormality” heavier than “warning” (second notification) so as to promptly confirm the user such as the cooling water tank.
That is, in normal vehicles, even if the engine cooling water is neglected and there is no notification even if the engine cooling water decreases, it is noticed until an abnormality such as overheating due to a decrease in the amount of engine cooling water occurs. I can't.
However, if the vehicle management according to the present invention notifies that maintenance is required, an abnormality can be prevented beforehand, and not only the amount of engine cooling water but also the amount of change in engine cooling water is judged. The “warning” or “abnormality” is notified without comparing with. Thereby, even if incorrect maintenance is performed, the user of the vehicle 1 can be made aware of the abnormality of the vehicle 1 before a serious failure occurs (before the liquid amount falls below the determination value).

In the present invention, the following vehicle management is also possible.
It is also possible to perform the first notification or the second notification by using the environment (low temperature etc.) around the vehicle 1 from the information of the various controllers 7A to 7C as well as the information of the various sensors 8A to 8D. .
In addition, the transition (change amount) of the liquid amounts of various consumables stored in the storage unit 14 of the electronic control unit 6 can be displayed on the notification unit (such as a monitor) 9 by a user operation. Thereby, for example, when the user wants to perform maintenance of the vehicle 1 before moving for a long distance, the desired information can be presented, so that the commercial value can be increased.
Furthermore, the determination result in the notification determination unit 12 of the electronic control unit 6 can be used as a reference when the various controllers 7A to 7C perform failure diagnosis.
Furthermore, the electronic control unit 6 can perform the first notification or the second notification not only from the liquid amount but also from the flow rate.

  The vehicle management apparatus of the present invention can be applied to various vehicles.
