Description

Technical Field

[0001] The technology disclosed in this specification relates to vehicles. Background Technology

[0002] Japanese Patent Application Publication No. 2024-025399 discloses a vehicle comprising: a drive unit housing a component to be lubricated within a housing; an electric oil pump that draws oil from the housing to supply oil to the component to be lubricated; and a control device for controlling the operation of the electric oil pump. The control device operates the electric oil pump when the vehicle is stationary. Summary of the Invention

[0003] In the vehicle registered under Japanese Patent Application Publication No. 2024-025399, the electric fuel pump operates even when the vehicle is stationary. Passengers can easily perceive the sound of the electric fuel pump operating when the vehicle is stationary. Since the source of this perceived sound is unclear, it causes discomfort to the passengers.

[0004] This manual provides a technology that can suppress discomfort to passengers.

[0005] In the first embodiment disclosed in this specification, a vehicle is disclosed.

[0006] Alternatively, the vehicle may include: a drive unit that houses components to be lubricated within a housing; an electric oil pump that draws oil from the housing and supplies oil to the components to be lubricated; and a control device that controls the operation of the electric oil pump.

[0007] The control device can also be configured to perform the following processes:

[0008] Pre-lubrication treatment, wherein, while the vehicle is stationary, the electric oil pump is activated under specified conditions; and

[0009] The report processing, upon performing the pre-lubrication treatment, outputs a prescribed notification message to at least one of the vehicle's user interface and the information terminal owned by the passenger.

[0010] According to the above configuration, when pre-lubrication is performed, a pre-defined notification is output to the vehicle's user interface or the passenger's information terminal. By confirming the notification, the passenger can identify the source of the perceived sound. Therefore, situations causing discomfort to the passenger can be suppressed.

[0011] In the second approach, as in the first approach described above, the control device is configured to prevent the pre-lubrication process from being performed until the vehicle has been stopped for a predetermined time.

[0012] Normally, the electric oil pump stops operating when the vehicle is stationary. Furthermore, after the vehicle stops, the oil supplied to the lubricated components inside the housing during operation gradually accumulates in the lower part of the housing. As the vehicle remains stationary for longer periods, the amount of oil accumulated in the lower part of the housing increases, raising the oil level inside the housing. In this situation, the stirring resistance of the components inside the housing increases. Pre-lubrication treatment lowers the oil level inside the housing, thereby reducing the stirring resistance of the components inside the housing. On the other hand, when the vehicle remains stationary for a short period, the oil level inside the housing is low. Therefore, the stirring resistance of the components inside the housing is low. In this case, the necessity of performing pre-lubrication treatment is lower. Based on the above structure, the control device prevents the execution of pre-lubrication treatment until the vehicle remains stationary for a predetermined time. Therefore, it is possible to prevent the unnecessary execution of pre-lubrication treatment.

[0013] In the third approach, the specified condition may also be met in the first or second approach described above, when the vehicle has switched from being in a state of never being ready to start (Ready OFF) to being ready to start (Ready ON).

[0014] If a vehicle is switched from being ready to start to being ready to start, it is highly likely that the vehicle will be stopped for an extended period of time. Therefore, it is important to perform pre-lubrication at the appropriate time.

[0015] In the fourth approach, or any of the first to third approaches described above, the vehicle may also include a battery that supplies power to the electric oil pump. The control device may also be configured to prevent the pre-lubrication process from being performed when the remaining battery level is below a predetermined value.

[0016] The battery also supplies power to devices other than the electric oil pump. Based on the above structure, by operating the electric oil pump, it is possible to prevent insufficient power supply to devices other than the electric oil pump.

[0017] In the fifth approach, or in the fourth approach described above, the control device is configured to limit the output of the drive unit when the pre-lubrication process is avoided due to the remaining amount of the battery being below a predetermined value.

[0018] When the remaining battery level is below a specified value, the amount of oil supplied to the drive unit may be insufficient. The above-described structure can prevent this situation from occurring. Attached Figure Description

[0023] First Embodiment

[0024] Reference Figure 1 , Figure 2 Vehicle 2 will now be described. Vehicle 2 is an electric vehicle driven by the rotary motor 30, which will be described later. Alternatively, vehicle 2 can also be a hybrid electric vehicle or a fuel cell vehicle. Figure 1 , Figure 2 The direction in the middle is based on the direction of vehicle 2. Figure 1 The direction FR indicates the front direction of vehicle 2 in the front-rear direction. Figure 1 The direction RR indicates the rearward direction of vehicle 2 in the longitudinal direction. Additionally, Figure 1 , Figure 2 The direction LH indicates the left side of vehicle 2 in the left-right direction. Figure 1 , Figure 2 The direction RH indicates the right side of vehicle 2 in the left-right direction. Furthermore, Figure 2 The direction UP indicates the top or bottom of vehicle 2 in the vertical direction. Figure 2 The direction DW indicates the top and bottom of vehicle 2 in the vertical direction.

[0025] like Figure 1 As shown, vehicle 2 includes a right front wheel 4, a left front wheel 6, a right rear wheel 8, a left rear wheel 10, a front drive unit 12A, a rear drive unit 12B, a main battery 14, an auxiliary battery 16, a control device 18, and a user interface 20. In this embodiment, the instrument panel is the user interface 20. Furthermore, in a variation, the user interface 20 may also be a speaker.

[0026] The front drive unit 12A drives the right front wheel 4 and the left front wheel 6, while the rear drive unit 12B drives the right rear wheel 8 and the left rear wheel 10. Vehicle 2 is illustrated as a four-wheel drive vehicle. In a variation, vehicle 2 may also be a two-wheel drive vehicle equipped with only either the front drive unit 12A or the rear drive unit 12B. The rear drive unit 12B has the same structure as the front drive unit 12A, except that it drives the right rear wheel 8 and the left rear wheel 10. The front drive unit 12A will be described below, while the description of the rear drive unit 12B will be omitted.

[0027] The front drive unit 12A includes a rotary motor 30, a transmission device 32, a power control unit 34, and a housing 36. The rotary motor 30, the transmission device 32, and the power control unit 34 are housed within the housing 36. The power control unit 34 is positioned at the rear, adjacent to the rotary motor 30 and the transmission device 32. The power control unit 34 converts the power supplied from the main battery 14 from direct current (DC) to alternating current (AC) and supplies it to the rotary motor 30. The rotary motor 30 generates driving force based on the AC power supplied from the power control unit 34. The transmission device 32 amplifies the driving force generated by the rotary motor 30 and distributes it to the right front wheel 4 and the left front wheel 6.

[0028] Reference Figure 2 The rotary motor 30 and the transmission device 32 housed in the housing 36 will be described.

[0029] The rotary motor 30 includes a stator core 40, a rotor 42, and an output shaft 44. The stator core 40 is fixed to a housing 36. Coil ends 40A are provided at the right and left ends of the stator core 40. The rotor 42 is supported on the housing 36 in a manner that allows it to rotate about the rotation axis of the rotary motor 30. In this embodiment, the rotation axis extends in a left-right direction. The output shaft 44 is connected to the rotor 42 and rotates integrally with the rotor 42. The output shaft 44 is hollow and has a through hole 46 extending along the rotation axis of the rotary motor 30.

[0030] The transmission device 32 includes a planetary gear unit 50 and a differential gear 60. The planetary gear unit 50 reduces the rotation of the output shaft 44 of the rotary motor 30. The differential gear 60 distributes the driving force of the rotary motor 30 transmitted via the planetary gear unit 50 to the right front wheel 4 and the left front wheel 6 (see reference). Figure 1 The rotary motor 30, planetary gear unit 50, and differential gear 60 are arranged on the same shaft. Furthermore, the structure of the transmission device 32 described below is an example; other types of structures can be appropriately adopted.

[0031] The planetary gear unit 50 includes a sun gear 52, multiple stepper pinions 54, a ring gear 56, and a gear carrier 58. The sun gear 52 is connected to the output shaft 44 of the rotary motor 30 and rotates integrally with the output shaft 44. Each of the multiple stepper pinions 54 has a large-diameter pinion P1 and a small-diameter pinion P2 with a smaller diameter than the large-diameter pinion P1. The large-diameter pinion P1 meshes with the sun gear 52. The small-diameter pinion P2 meshes with the ring gear 56. The ring gear 56 is fixed to the housing 36. The gear carrier 58 supports the multiple stepper pinions 54 so that they can rotate. Thus, the sun gear 52 of the planetary gear unit 50 is the input component, the ring gear 56 is the reaction force component, and the planet carrier 58 is the output component.

[0032] The differential gear 60 includes a differential housing 62 and a differential gear mechanism 64. The differential housing 62 is supported on the housing 36 in a manner that allows it to rotate about the rotation axis of the rotary motor 30. The differential housing 62 is connected to the planet carrier 58 of the planetary gear section 50 and rotates integrally with the planet carrier 58. The differential gear mechanism 64 is housed within the differential housing 62.

[0033] The differential gear mechanism 64 includes a pinion shaft 66, a pair of differential pinions 68 and 70, a right-side gear 72, and a left-side gear 74.

[0034] The pinion shaft 66 is connected to the differential housing 62 and rotates integrally with it. The pinion shaft 66 extends within the differential housing 62 in a direction orthogonal to the rotation axis of the rotary motor 30. A pair of differential pinions 68 and 70 are supported on the pinion shaft 66 in a manner that allows them to rotate about the pinion shaft 66. The right gear 72 is a component that outputs driving force to the right front wheel 4 and meshes with the pair of differential pinions 68 and 70. The left gear 74 is a component that outputs driving force to the left front wheel 6 and meshes with the pair of differential pinions 68 and 70.

[0035] The front drive unit 12A also includes an intermediate shaft 80 and a right front wheel 4 (see reference). Figure 1 The right drive shaft 82 and the left front wheel 6 (see reference) are connected. Figure 1 The left drive shaft 84 is connected.

[0036] The intermediate shaft 80 extends along the rotation axis of the rotary motor 30 within the through hole 46 of the output shaft 44. The left end of the intermediate shaft 80 is connected to the right gear 72 of the differential gear 60, and the right end of the intermediate shaft 80 is connected to the right drive shaft 82. That is, the intermediate shaft 80 transmits the torque of the rotary motor 30, which is transmitted via the output shaft 44, the planetary gear section 50, and the differential gear mechanism 64, to the right front wheel 4.

[0037] The right end of the left drive shaft 84 is connected to the left gear 74. The driving force output by the left gear 74 is directly transmitted to the left drive shaft 84.

[0038] Vehicle 2 is equipped with an electric oil pump 90 and an oil cooler 92. Additionally, in Figure 2 In the diagram, the flow of oil is represented by dashed lines. The oil cooler 92 cools the oil. When the electric oil pump 90 operates, the oil inside the housing 36 is drawn in. Specifically, the electric oil pump 90 draws in the oil that has accumulated in the lower part of the housing 36. The oil drawn in by the electric oil pump 90 is discharged through the oil cooler 92 toward the components to be lubricated and cooled within the housing 36. The rotary motor 30 and the transmission device 32 are examples of components to be lubricated and cooled.

[0039] One example of the oil discharge location will be described. Oil is discharged from the top of the housing 36 toward the coil end 40A of the stator core 40. Additionally, oil is discharged from the upper part of the housing 36 toward the transmission device 32. Furthermore, oil is discharged into the interior of the housing 36 through a through hole 46 along the rotation axis direction of the output shaft 44 and through a through hole on the outer peripheral surface of the output shaft 44. Additionally, oil is discharged toward the differential gear 60 through a through hole in the intermediate shaft 80 along the rotation axis direction.

[0040] Figure 1 The main battery 14 is a battery that supplies power to the power control unit 34. The main battery 14 is a secondary battery formed by connecting multiple battery cells in series. As an example, the main battery 14 is located under the floor of the vehicle 2.

[0041] Auxiliary battery 16 is a battery that supplies power to auxiliary equipment. Auxiliary equipment includes an electric oil pump 90, an oil cooler 92, lighting equipment, audio equipment, car navigation systems, and dashcams. Auxiliary battery 16 is a secondary battery formed by connecting multiple battery cells in series. The rated voltage of auxiliary battery 16 is lower than the rated voltage of main battery 14. For example, the rated voltage of auxiliary battery 16 is 12V, while the rated voltage of main battery 14 is 200V to 600V. For example, auxiliary battery 16 is located below the luggage compartment in the rear compartment of vehicle 2.

[0042] The control device 18 is configured as a computer equipped with a processor, RAM, ROM, and other memory. The control device 18 controls the operation of various parts of the vehicle 2 according to a program stored in the ROM, etc.

[0043] The control device 18 is configured to selectively execute a normal driving mode and a restricted driving mode. The restricted driving mode is a mode that limits the output of the front drive unit 12A and the rear drive unit 12B compared to the normal driving mode.

[0044] Electric oil pump handling ( Figure 3 )

[0045] Reference Figure 3 The electric oil pump processing performed by the control device 18 of vehicle 2 will be described. When vehicle 2 switches from a state where start-up preparation has not yet been completed (Ready OFF) to a state where start-up preparation has been completed (Ready ON), the control device 18 begins... Figure 3 The processing. Here, "not ready to start" means the power supply to vehicle 2 is disconnected. "Ready to start" means the power supply to vehicle 2 is connected, indicating a state where the rotary motor 30 and power control unit 34 can be driven. Furthermore, in Figure 3 At the beginning, the electric oil pump 90 stops.

[0046] In S10, the control device 18 determines whether the stopping time of vehicle 2 exceeds a predetermined time. Hereinafter, the stopping time of vehicle 2 will be recorded as "stopping time". If the stopping time exceeds the predetermined time (S10: Yes), the control device 18 proceeds to S20. On the other hand, if the stopping time does not exceed the predetermined time (S10: No), the control device 18 proceeds to S40. In this embodiment, the predetermined time is fixed. In variations, the predetermined time may vary depending on factors such as the outside air temperature and the previous driving time. For example, the shorter the previous driving time, the shorter the predetermined time. Alternatively, the lower the outside air temperature, the longer the predetermined time.

[0047] In S40, the control device 18 determines whether the vehicle 2 has started moving. Specifically, the control device 18 determines whether the state of the vehicle 2 has changed from a stopped state to a moving state. If the state of the vehicle 2 has changed from a stopped state to a moving state (S40: Yes), the control device 18 terminates the process. Figure 3 The processing is as follows. On the other hand, if the state of the vehicle 2 has not switched from the stopped state to the driving state (no in S40), the control device 18 returns to S10.

[0048] In S20, the control device 18 determines whether the remaining amount of the auxiliary battery 16 exceeds a first predetermined value. If the remaining amount of the auxiliary battery 16 exceeds the first predetermined value (S20: Yes), the control device 18 proceeds to S22. On the other hand, if the remaining amount of the auxiliary battery 16 does not exceed the first predetermined value, that is, if the remaining amount of the auxiliary battery 16 is below the first predetermined value (S20: No), the control device 18 proceeds to S30.

[0049] In S22, the control device 18 performs a pre-lubrication process to activate the electric oil pump 90. This draws in the oil accumulated in the lower part of the housing 36 and supplies oil into the housing 36. Therefore, the oil level in the housing 36 can be lowered, and oil can be supplied to the components within the housing 36 that require lubrication.

[0050] In step S24, control device 18 performs report processing, outputting a specified notification message to the user interface 20 of vehicle 2. The specified notification message indicates that pre-lubrication processing is being performed. If step S24 ends, control device 18 terminates. Figure 3 The processing.

[0051] Additionally, in S30, control device 18 switches from normal driving mode to restricted driving mode. That is, if the remaining amount of auxiliary battery 16 is below a first predetermined value, control device 18 does not perform the pre-lubrication process that activates electric oil pump 90. Control device 18 terminates when S30 ends. Figure 3The control device 18 handles situations where the remaining amount of the auxiliary battery 16 exceeds a second predetermined value during driving, switching from a restricted driving mode to a normal driving mode. The second predetermined value may be the same as or greater than the first predetermined value.

[0052] As described above, the following conditions are met: vehicle 2 has switched from not completing start preparation to completing start preparation, the stop time exceeds the predetermined time (yes in S10), and the remaining amount of auxiliary battery 16 exceeds the first predetermined value (yes in S20). In this case, control device 18 performs pre-lubrication processing (S22) and reporting processing (S24).

[0053] The effect of this embodiment

[0054] As described above, vehicle 2 includes a front drive unit 12A (an example of a "drive unit") housing components to be lubricated, an electric oil pump 90, and a control device 18 for controlling the operation of the electric oil pump 90, all housed within housing 36. The electric oil pump 90 draws oil from housing 36 and supplies oil to the components to be lubricated. The control device 18 is configured to perform pre-lubrication processing (S22) and reporting processing (S24) when vehicle 2 is stationary, provided certain conditions are met.

[0055] According to the above structure, when pre-lubrication is performed, a specified notification message is displayed (output) on the instrument panel of vehicle 2. By confirming the specified notification message, passengers can identify the source of the sound they perceive. Therefore, situations that cause discomfort to passengers can be suppressed.

[0056] In addition, by operating the electric oil pump 90, the oil level inside the housing 36 can be lowered during parking, and oil can be supplied to the components inside the forward drive unit 12A.

[0057] Furthermore, the control device 18 is configured to, before the vehicle 2 stops for a predetermined time (in Figure 3 (If S10 is not specified), avoid performing the pre-lubrication process.

[0058] Normally, when vehicle 2 is stationary, the electric oil pump 90 stops operating. Furthermore, after vehicle 2 stops, the oil supplied to the lubricated components inside housing 36 during operation gradually accumulates in the lower part of housing 36. As the time vehicle 2 remains stationary increases, the amount of oil accumulated in the lower part of housing 36 increases, and the oil level inside housing 36 rises. In this case, the stirring resistance of the components inside housing 36 increases. When pre-lubrication is performed, the oil level inside housing 36 can be lowered. Therefore, the stirring resistance of the components inside housing 36 can be reduced. On the other hand, when the time vehicle 2 remains stationary is relatively short, the oil level inside housing 36 is low. Therefore, the stirring resistance of the components inside housing 36 is low. In this case, the necessity of performing pre-lubrication is lower. According to the above structure, the control device 18 avoids performing pre-lubrication until the stationary state of vehicle 2 exceeds a predetermined time. Therefore, it is possible to suppress the unnecessary performance of pre-lubrication when vehicle 2 is stationary.

[0059] In addition, the specified conditions are met if vehicle 2 has never completed the start preparation and has switched to the point where the start preparation has been completed.

[0060] If vehicle 2 is switched from being ready to start to being ready to start, there is a high probability that vehicle 2 will be stopped for an extended period of time. Therefore, it is necessary to perform pre-lubrication at an appropriate time.

[0061] In addition, vehicle 2 also has an auxiliary battery 16 (an example of a "battery") that supplies power to the electric oil pump 90. The control device 18 is configured to prevent the execution of pre-lubrication treatment when the remaining amount of the battery is below a first predetermined value (an example of a "predetermined value") (not in S20).

[0062] The auxiliary battery 16 also supplies power to equipment other than the electric oil pump 90. Based on the above structure, by operating the electric oil pump 90, it is possible to prevent insufficient power supply to equipment other than the electric oil pump 90.

[0063] Furthermore, the control device 18 is configured to limit the output of the front drive unit 12A when the pre-lubrication process is avoided due to the condition that the remaining amount of the auxiliary battery 16 is below a first predetermined value (no in S20).

[0064] If the remaining amount of auxiliary battery 16 is below a first predetermined value, the amount of oil supplied to the forward drive unit 12A may be insufficient. According to the above structure, the situation of insufficient oil supply to the forward drive unit 12A can be suppressed.

[0065] Second Embodiment

[0066] The second embodiment will be described below. In this embodiment, Figure 3The processing content of S24 in this embodiment differs from that of S24 in the first embodiment. Furthermore, in this embodiment, the vehicle 2 and the information terminal 100 owned by the passenger (see reference...) Figure 1 A wireless connection has been established between them.

[0067] In S24, the control device 18 uses a wireless connection with the information terminal 100 to send a predetermined notification message to the information terminal 100. Upon receiving the predetermined notification message from the vehicle 2, the information terminal 100 displays the message. By checking the notification message displayed on the information terminal 100, the passenger can understand the cause of the perceived sound. Therefore, situations causing discomfort to the passenger can be suppressed.

[0068] The above details specific examples of the technology disclosed in this specification, but these are merely illustrative and do not limit the scope of the claims. The technology described in the claims includes technologies obtained by various modifications and alterations to the specific examples illustrated above.

[0069] (First variation) In Figure 3 In S24, prescribed notification information can also be output to both the user interface 20 of vehicle 2 and the information terminal 100 owned by the passenger.

[0070] (Second Modification) The control device 18 may also start when it detects that a user has approached the vehicle 2, or that a user holding the key to the vehicle 2 has touched the door of the vehicle 2. Figure 3 The processing is as follows. In another variation, the control device 18 can also estimate the prescribed start time of driving based on the user's past driving history. Furthermore, the control device 18 can also start the process at the prescribed start time of driving or at a time predetermined before the prescribed start time of driving. Figure 3 The processing. In other words, the control device 18 begins processing upon detecting the user's driving intention. Figure 3 The processing.

[0071] (Third variation) can be omitted Figure 3 S10, S20, S30, and S40. That is, the control device 18 can also determine that the specified conditions are met when the vehicle 2 has not completed the start preparation and has completed the start preparation, and perform pre-lubrication treatment (S22) and report processing (S24).

[0072] (Fourth variation) can be omitted Figure 3 S20 and S30. In this modified example, if the vehicle 2 has not completed the start preparation and has switched to the start preparation and the stop time exceeds the specified time (S10: Yes), the control device 18 determines that the specified conditions are met and performs pre-lubrication treatment (S22) and report treatment (S24).

[0073] (Fifth Modification) The control device 18 may also not be configured to execute a restricted driving mode. In this modification, it can be omitted. Figure 3 S30. In this modified example, if the control device 18 determines "no" in S20, it terminates. Figure 3 The processing.

[0074] (Sixth Modification) Control device 18 can also be in Figure 3 If the determination in step 20 is negative, the charging process of charging the auxiliary battery 16 using the main battery 14 begins. In this modified example, the control device 18 can switch from the restricted driving mode to the normal driving mode and execute the processes in S22 and S24 when the vehicle 2 is stopped and the remaining amount of the auxiliary battery 16 exceeds the second predetermined value.

[0075] (Seventh Modification) Control device 18 may also execute S20 before S10. In this modification, if control device 18 determines that the remaining amount of auxiliary battery 16 exceeds a first predetermined value, it executes S10, S22, S24, S30, and S40. On the other hand, if control device 18 determines that the remaining amount of auxiliary battery 16 does not exceed the first predetermined value, it executes charging processing. Then, if the remaining amount of auxiliary battery 16 exceeds a second predetermined value, control device 18 executes processing S10, S22, S24, S30, and S40.

[0076] (Eighth Modification) In various embodiments, the front drive unit 12A and the rear drive unit 12B are so-called single-axis eAxles (electric drive bridges). In a modification, the front drive unit 12A and the rear drive unit 12B may also be three-axis eAxles, etc.

[0077] Furthermore, the technical elements illustrated in this specification or drawings exert their technical usefulness individually or in various combinations, and are not limited to the combinations recited in the claims at the time of application. Additionally, the technology illustrated in this specification or drawings simultaneously achieves multiple objectives, and achieving one of these objectives is itself technically useful.
