Description

  The present disclosure relates to an electronic control device mounted on a vehicle.

Conventionally, a technique for finding an optimum value of a control constant, which is a value used for vehicle control, is known. Such a technique is also called adaptation.
Patent Document 1 proposes a technique for adapting a fuel injection period as a control constant. The fuel injection period is a value used for controlling an engine mounted on the vehicle, and refers to a period during which fuel is injected by the fuel injection valve.

JP 2007-71166 A

  As described above, “adaptation” means that the control constant is set to an optimal value (hereinafter referred to as the optimal value) so that the electronic control device (hereinafter referred to as ECU) mounted on the vehicle can appropriately perform control based on the control constant. To be done. ECU is an abbreviation for Electronic Control Unit. The adaptation is performed by the operator performing the adaptation using an adaptation device. The adaptive device is a device outside the vehicle and is connected to the ECU so as to be communicable.

  The control constant can be a value generated according to a predetermined generation method using the adaptation constant. The operator appropriately inputs a plurality of types of adaptation constants to the adaptation device, and causes the adaptation device to generate control constants according to the generation method for each input adaptation constant. The worker causes the vehicle to perform control using the generated control constant, and determines whether or not control based on the control constant is appropriately performed in the vehicle. Then, when the most suitable control result is obtained, the worker uses the adaptation device to record the control constant at this time in a memory provided in the ECU of the vehicle, and finishes the adaptation.

  Thus, the control constant set to the optimum value by the adaptation can be adapted again according to, for example, improvement of the performance of the vehicle, change of the country in which the vehicle is used, or the like. That is, the control constant can be reset to a new optimum value.

  However, in the conventional ECU, it is general that only a control constant as a result of the adaptation is recorded in a memory provided in the ECU. That is, when performing the adjustment, it is difficult for the operator to know what adjustment constant is calculated based on the control constant stored in the memory included in the ECU.

  For this reason, the operator who performs the calibration has an idea of what new calibration constants should be input to the calibration device to generate new control constants for the control constants recorded in the memory. There was a problem that it was difficult to adapt and difficult to adapt. That is, it is not easy to set the control constant based on the adaptation constant.

  One aspect of the present disclosure provides a technique for easily setting a control constant for controlling a vehicle based on a matching constant.

  One aspect of the present disclosure is an electronic control device (15) mounted on the vehicle (1), and includes a recording instruction acquisition unit (S110) and a recording execution unit (S130). The recording instruction acquisition unit acquires a recording instruction that is an instruction to record at least a control constant and a compatible constant from the compatible device (60). The recording execution unit records at least the control constant and the compatible constant in the vehicle recording unit (55) in association with each other. The adaptive device is a device outside the vehicle, and is communicably connected to the electronic control device, and is configured to generate a control constant according to a predetermined generation method using the adaptive constant and output a recording instruction. Is done. The control constant is a value for performing predetermined control in the vehicle. The adaptation constant is a value input to the adaptation device. The vehicle recording unit is a rewritable memory mounted on the vehicle.

  According to this, the worker can perform the adaptation while referring to the adaptation constant recorded in the vehicle recording unit as appropriate. For this reason, the control constant for controlling the vehicle is based on the conformance constant rather than the conventional ECU, which is not recorded with the conformance constant and it is difficult to determine the conformance constant for generating the control constant. It can be set easily.

  Note that the reference numerals in parentheses described in this column and in the claims indicate the correspondence with the specific means described in the embodiment described later as one aspect, and the technical scope of the present disclosure It is not limited.

The control here may include various controls executed by the ECU 15. The adaptation constant is input to the adaptation device 60 by the operator. The adaptation device 60 calculates a control constant according to a predetermined generation method using the adaptation constant input to the adaptation device 60 by the operator.

The generation method here may include various arithmetic expressions for calculating the control constant using the adaptation constant. Specific examples of the control constant, the adaptation constant, and the generation method will be described later.
The adaptation device 60 includes an input reception unit 61, an adaptation communication unit 62, an adaptation display unit 63, and an adaptation control unit 65. The input receiving unit 61 receives an input from the worker and outputs it to the adaptation control unit 65. The suitable communication unit 62 is connected to the vehicle communication unit 13 in the vehicle 1 and communicates with the vehicle communication unit 13. The conformity display unit 63 displays an image in accordance with an instruction from the conformance control unit 65. The adaptation control unit 65 is configured around a known microcomputer including a CPU 71 and a memory 72 having a ROM, a RAM, a rewritable EEPROM, and the like.

  When the adaptation constant is input to the input receiving unit 61 by the operator, the adaptation control unit 65 generates a control constant according to a generation method determined in advance according to the adaptation constant. The generation method corresponding to the adaptation constant is recorded in the memory 72 of the adaptation control unit 65 in advance.

  Further, when a request for writing the generated control constant into the memory 52 of the vehicle 1 (hereinafter, a write request) is input to the input receiving unit 61 by the operator, the matching control unit 65 sends the matching communication unit 62 to the vehicle 1. To output a recording instruction. The recording instruction is an instruction that records at least the control constant and the compatible constant in the memory 52 provided in the vehicle 1 in association with each other.

  In the present embodiment, the matching control unit 65 includes a control constant, a matching constant used when the control constant is generated, and an instruction to be recorded in the EEPROM 55 included in the vehicle 1 in association with each other. Output instructions.

  In addition, when a request for reading a control constant recorded in a memory included in the vehicle 1 (hereinafter referred to as a read request) is input to the input receiving unit 61 by an operator, the matching control unit 65 sends the matching communication unit 62 to the vehicle 1. The output instruction is output via. The output instruction is an instruction for requesting the ECU 15 to output at least a control constant to the adaptive device 60. In the present embodiment, the adaptation control unit 65 outputs an instruction that requests the ECU 15 to output a control constant to the adaptation device 60 as an output instruction.

  Further, the adaptation control unit 65 is output from the ECU 15 of the vehicle 1 in accordance with an adaptation constant input to the input receiving unit 61, a control constant generated according to the generation method based on the adaptation constant, and an output instruction as will be described later. An image showing the control constant, the adaptation constant, etc. is displayed on the adaptation display unit 63.

[Control constant]
Here, an example of control constants to be matched will be described. In the present embodiment, for example, as shown in FIG. 2, the maximum value of torque output from the engine 12 in accordance with the engine speed (hereinafter, designated maximum torque) is set as a control constant X.

  In the present embodiment, the maximum allowable torque with respect to the engine speed is set as the first adaptation constant A. The allowable maximum torque is a torque value determined in advance for each engine speed range, and is a torque value allowed to be output from the engine 12. The allowable maximum torque can be set to a different value for each country where the vehicle 1 is shipped.

  The allowable maximum torque as the first adaptation constant A is set to Q1 when the engine speed is 0 or more and less than P1. Further, when the engine speed is P1 or more and less than P2, P2 or more and less than P3, or P3 or more and less than P4, the allowable maximum torque corresponding to each is set to Q2, Q3, and Q4. Each allowable maximum torque is assumed to be set to Q1 <Q2 <Q3 <Q4.

  In the present embodiment, the component protection maximum torque is set as the second matching constant B. The component protection maximum torque is a torque value that is set so that a load applied to a mechanical component, an electrical component, or the like used to output the torque does not exceed a magnitude allowed for the component. The component protection torque can be a different value depending on the type or grade of the vehicle 1.

  In the present embodiment, an arithmetic expression represented by Expression (1) is set in advance as a generation method.

Thereby, in this embodiment, a small value is set as the control constant X among the first adaptation constant A and the second adaptation constant B.
For example, it is assumed that a value R as the first adaptation constant A and the second adaptation constant B is input to the adaptation device 60 by the operator. Here, Q2 <R <Q3.

  In this case, the adaptation device 60 calculates Q1 as the control constant X when the engine speed is less than P1. Further, when the engine speed is P1 or more and less than P2, Q2 is calculated as the control constant X. Further, when the engine speed is P2 or more and less than P3, or when it is P3 or more and less than P4, R is calculated as the control constant X.

  For example, the worker performs adaptation while monitoring whether or not the engine 12 is appropriately controlled so that the torque output from the engine 12 in the vehicle 1 is not insufficient. That is, the operator monitors the torque shortage and appropriately changes the value of the allowable maximum torque as the first adaptation constant A or the component protection maximum torque as the second adaptation constant B, and changes each engine rotation. Find the optimal value of the control constant X in the number.

  As described above, the matching constant for calculating the control constant may be one or more. Further, the adaptation constant is a value for performing predetermined control in the vehicle 1 and may be a value indicating the operating state of the vehicle 1 and the characteristics of the vehicle 1.

  In this embodiment, the control constant X and the first adaptation constant A are recorded in the EEPROM 55 in a table format, and the second adaptation constant B is recorded in the EEPROM 55 as one predetermined value. However, the present invention is not limited to this. The control constant and the adaptation constant can be recorded in the EEPROM 55 in an arbitrary recording manner such as a table format, a map format, a predetermined value, or the like.

[1-2-1. Conformance record processing]
Next, the adaptation recording process executed by the ECU 15 when the ECU 15 is connected to the adaptation device 60 will be described with reference to the flowchart of FIG. The conforming recording process is started when the recording instruction is received from the conforming device 60 via the vehicle communication unit 13.

  In S110, the ECU 15 acquires a recording instruction. The recording instruction includes, for example, a control constant X as shown in FIG. 2, conformance constants such as a first conformance constant A and a second conformance constant B, and an instruction for requesting these to be recorded in the EEPROM 55. It is.

  In S120, the ECU 15 acquires a control constant and a compatible constant included in the recording instruction from the recording instruction. For example, the ECU 15 acquires the control constant X, the first adaptive constant A, and the second adaptive constant B from the above-described recording instruction.

  In S130, the ECU 15 records the content instructed to be recorded in the recording instruction in the EEPROM 55. That is, the ECU 15 associates the control constant and the adaptation constant acquired in S120 with each other and records them in the EEPROM 55. And this conformity recording process is complete | finished. For example, the ECU 15 records the control constant X, the first adaptation constant A, and the second adaptation constant B in the EEPROM 55 in association with each other.

As a result, the control constant is recorded in the ECU 15, and the matching constant used for generating the control constant is also recorded in the ECU 15.
[1-2-2. Conformity output processing]
Next, the adaptation output process executed by the ECU 15 when the ECU 15 is connected to the adaptation device 60 will be described with reference to the flowchart of FIG. The adaptive output process is started when the output instruction is received from the adaptive device 60 via the vehicle communication unit 13.

In S210, the ECU 15 obtains an output instruction. The output instruction can be, for example, an instruction requesting that the control constant X described above be output to the adaptation device 60.
In S220, the ECU 15 acquires from the EEPROM 55 the control constant instructed by the output instruction and the compatible constant recorded in the EEPROM 55 in association with the control constant. For example, after the adaptation is performed by the operator as described above, the EEPROM 55 has a control constant X, a first adaptation constant A and a second adaptation constant B associated with the control constant X, and Is recorded. For example, the ECU 15 acquires the control constant X, the first adaptation constant A, and the second adaptation constant B from the EEPROM 55 according to the output instruction.

  In S230, the ECU 15 outputs the control constant and the adaptation constant acquired from the EEPROM 55 in S220 to the adaptation device 60. Then, the conforming output process ends. For example, the ECU 15 outputs the control constant X, the first adaptation constant A, and the second adaptation constant B to the adaptation device 60.

[1-2-3. Operation]
The ECU 15 configured as described above is communicably connected to the adapting device 60 and is operated as follows when the adapting is performed by the worker.

As shown in FIG. 5, the worker who performs matching inputs a read request to the matching device 60. Then, an output instruction is output from the matching device 60 to the ECU 15.
The ECU 15 outputs the control constant recorded by the output instruction, which is recorded in the EEPROM 55, and the matching constant recorded in the EEPROM 55 in association with the control constant to the matching device 60. In the adaptation device 60, an image indicating the control constant and the adaptation constant recorded in the ECU 15 is displayed on the adaptation display unit 63.

  The worker inputs a new compatible constant to the input receiving unit 61 while referring to the compatible constant output from the ECU 15. The input new matching constant is displayed on the matching display unit 63. The adaptation device 60 generates the control constant according to the generation method using the input adaptation constant.

  The worker causes the vehicle 1 to perform control using the generated control constant, and determines whether the vehicle 1 is appropriately controlled based on the control constant. That is, the operator appropriately inputs a plurality of types of compatible constants to the adaptive device 60, and causes the adaptive device 60 to output a recording instruction each time the adaptive constants are input so that the ECU 15 writes the control constant and the adaptive constant. The adaptation ends when the most appropriate control result is obtained in the vehicle 1.

As a result, the EEPROM 55 provided in the ECU 15 records the control constant when the most appropriate control result is obtained and the adaptation constant for generating the control constant.
It should be noted that the control constant set to the optimum value by the adaptation can be adapted again according to, for example, the improvement of the vehicle performance or the change of the country in which the vehicle is used, and can be reset to a new optimum value. In the present embodiment, when performing re-adaptation, the operator can output an output instruction to the adapting device 60 and obtain a control constant already recorded in the EEPROM 55 included in the vehicle 1 together with the adapting constant. That is, the operator can perform re-adaptation while referring to the control constant and the adaptation constant at the previous adaptation.

According to the first embodiment described in detail above, the following effects are obtained.
(1a) The ECU 15 is mounted on the vehicle 1. In S110, the ECU 15 obtains a recording instruction that is an instruction for recording at least the control constant and the adaptive constant from the adaptive device 60. In S130, the ECU 15 records at least the control constant and the compatible constant in the EEPROM 55 in association with each other. The adapting device 60 is a device outside the vehicle, is communicably connected to the ECU 15, and is configured to generate a control constant according to a predetermined generation method using the adapting constant and output a recording instruction. ing. The control constant is a value for performing predetermined control in the vehicle. The adaptation constant is a value input to the adaptation device 60. The EEPROM 55 is a rewritable memory mounted on the vehicle.

  According to this, the operator can perform the adaptation while referring to the adaptation constant recorded in the EEPROM 55 as appropriate. For this reason, the control constant is not recorded, that is, the control constant is recorded, that is, the vehicle is controlled more than the conventional ECU that is difficult to determine the suitable constant for generating the control constant. Therefore, the control constant can be easily set based on the adaptation constant.

  Further, when re-adapting the control constant, the operator appropriately sets the adaptation constant recorded in the EEPROM 55, for example, by setting a value near the adaptation constant recorded in the EEPROM 55 as a new adaptation constant. While referring, it becomes possible to efficiently reset the control constant based on the adaptation constant.

  (1b) In S210, the ECU 15 obtains an output instruction that is an instruction to output at least a control constant from the adaptation device 60 to the adaptation device 60. In S230, the ECU 15 acquires the control constant instructed in the output instruction and the compatible constant recorded in the EEPROM 55 in association with the control constant from the EEPROM 55, and outputs the control constant and the compatible constant to the adaptive device 60. To do.

  According to this, when there is an instruction to output the control constant from the adaptation device 60, the ECU 15 outputs the control constant and the adaptation constant to the adaptation device 60, so that the adaptation device 60 acquires the control constant and the adaptation constant. be able to. As a result, the operator can easily set the control constant based on the adaptation constant while referring to the acquired control constant and the adaptation constant.

[2. Second Embodiment]
[2-1. Difference from the first embodiment]
Since the basic configuration of the second embodiment is the same as that of the first embodiment, differences will be described below. Note that the same reference numerals as those in the first embodiment indicate the same configuration, and the preceding description is referred to.

  In the first embodiment described above, the ECU 15 records the control constant and the compatible constant in the EEPROM 55 in association with each other. On the other hand, the second embodiment is different from the first embodiment in that the control constant, the adaptation constant, and the generation method are recorded in the EEPROM 55 in association with each other.

[2-2. processing]
[2-2-1. Conformance record processing]
Next, the conformity recording process in the present embodiment executed by the ECU 15 of the second embodiment instead of the conformity recording process of the first embodiment will be described with reference to the flowchart of FIG.

  In S110, the ECU 15 acquires a recording instruction. In the present embodiment, the recording instruction is an instruction for recording the control constant, the adaptive constant, and the generation method in the EEPROM 55. That is, the control constant, the compatible constant, the generation method, and the instruction for recording these in the EEPROM 55 are included in the recording instruction.

In S121, the ECU 15 acquires a control constant, a compatible constant, and a generation method included in the recording instruction from the recording instruction.
In S123, the ECU 15 acquires a comparison value. The comparison value is a value generated in accordance with the generation method instructed by the recording instruction using the adaptation constant instructed by the recording instruction received by the ECU 15. The comparison value is generated by the ECU 15 by a process other than the conformity recording process, and the ECU 15 acquires the comparison value in this step. However, it is not limited to this. In this step, the ECU 15 may be configured to generate a comparison value.

  In S125, the ECU 15 determines whether or not the control constant instructed by the recording instruction matches the comparison value. The ECU 15 shifts the process to S130 when the instructed control constant and the comparison value match, and ends the conformity recording process when they do not match.

  The ECU 15 records the contents instructed to be recorded in the recording instruction in the EEPROM 55 in S130 which is shifted when the instructed control constant and the comparison value match. That is, the ECU 15 records the adaptive constant, the control constant, and the generation method instructed by the recording instruction in the EEPROM 55 in association with each other. Then, the ECU 15 ends the conformity recording process.

[2-2-2. Conformity output processing]
Next, the adaptive output process in the present embodiment that is executed by the ECU 15 of the second embodiment instead of the adaptive output process of the first embodiment will be described with reference to the flowchart of FIG. Note that the processing of S210 in FIG. 7 is substantially the same as the processing of S210 in FIG.

In S210, the ECU 15 obtains an output instruction.
In S225, the ECU 15 acquires from the EEPROM 55 the control constant instructed by the output instruction and the compatible constant and generation method recorded in the EEPROM 55 in association with the control constant.

  In S235, the ECU 15 outputs the control constant, the matching constant, and the generation method acquired from the EEPROM 55 in S225 to the matching device 60. Then, the conforming output process ends.

In S130, the ECU 15 causes the EEPROM 55 to record the matching constant, the control constant, and the generation method specified by the recording instruction in association with each other.

  According to this, since the adaptive constant and the generation method are recorded together with the control constant in the EEPROM 55, even if the generation method is not recorded in the adaptation device 60, the generation method recorded in the EEPROM 55 is acquired. Adaptation can be performed based on the generation method.

  (2b) In S123, the ECU 15 acquires a comparison value, which is a value generated according to the generation method instructed by the recording instruction, using the adaptation constant instructed by the recording instruction. In S125, the ECU 15 determines whether or not the control constant instructed by the recording instruction matches the comparison value. In S130, the ECU 15 causes the EEPROM 55 to record in the case where it is determined in S125 that they match.

  According to this, when the control constant included in the recording instruction and the comparison value match, the ECU 15 has transmitted and received the recording instruction without a communication error in the communication path between the ECU 15 and the adapting device 60. It becomes possible to judge. In addition, the ECU 15 records the control constant, the compatible constant, and the generation method in the EEPROM 55 when they match, so that it is recorded in the EEPROM 55 after confirming that no communication error has occurred in the communication path. Is possible.

Note that the ECU 15 may record at least the control constant and the compatible constant in the EEPROM 55 in association with each other.
(2c) In S210, the ECU 15 obtains an output instruction, which is an instruction for causing the adaptive device 60 to output at least a control constant, from the adaptive device 60. In S235, the ECU 15 acquires from the EEPROM 55 the control constant instructed in the output instruction and the compatible constant and the generation method recorded in the EEPROM 55 in association with the control constant. Is output to the adapting device 60.
