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 controlling a vehicle, has been known. Such techniques are also called conformance.
Patent Document 1 proposes a technique for adapting the fuel injection period as a control constant. The fuel injection period is a value used for controlling an engine mounted on a vehicle, and refers to a period during which fuel is injected by a fuel injection valve.

JP-A-2007-71166

Conformity means that, as described above, the control constant is set to the optimum value (hereinafter, the optimum value) so that the electronic control device (hereinafter, the ECU) mounted on the vehicle appropriately controls the control based on the control constant. To be done. ECU is an abbreviation for Electronic Control Unit. Conformance is performed by the conforming operator using the conforming device. The conforming device is a device outside the vehicle and is communicably connected to the ECU.

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

The control constants set to the optimum values by conforming in this way can be adapted again in response to, for example, improvement of vehicle performance or change of country in which the vehicle is used. That is, the control constant can be reset to a new optimum value.

However, in the conventional ECU, it is common that only the control constant as a result of conformity is recorded in the memory provided in the ECU. That is, when performing the matching, it is difficult for the operator to know what kind of matching constant the control constant stored in the memory provided in the ECU is based on.

Therefore, the conforming operator has no idea what kind of new conforming constant should be input to the conforming device to generate a new control constant for the control constant recorded in the memory. There was a problem that it was difficult to attach and fit. That is, it was not easy to set the control constant based on the matching constant.

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

One aspect of the present disclosure is an electronic control device (15) mounted on a vehicle (1), which includes a recording instruction acquisition unit (S110) and a recording execution unit (S130). The recording instruction acquisition unit acquires a recording instruction, which is an instruction for recording at least the control constant and the conforming constant, from the conforming device (60). The recording execution unit causes the vehicle recording unit (55) to record at least the control constant and the conformity constant in association with each other. The conforming device is a device outside the vehicle, is communicably connected to the electronic control device, generates a control constant according to a predetermined generation method using the conforming constant, and outputs a recording instruction. Will be done. The control constant is a value for performing predetermined control in the vehicle. The matching constant is a value input to the matching device. The vehicle recording unit is a rewritable memory mounted on the vehicle.

According to this, the operator can perform the conforming while appropriately referring to the conforming constant recorded in the vehicle recording unit. For this reason, the control constant for controlling the vehicle is based on the conformity constant as compared with the conventional ECU in which the conformity constant is not recorded and it is difficult to guess the conformity constant for generating the control constant. It can be set easily.

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

The conforming device 60 includes an input receiving unit 61, a conforming communication unit 62, a conforming display unit 63, and a conforming control unit 65. The input receiving unit 61 receives the input from the operator and outputs it to the conforming control unit 65. The conforming 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 according to an instruction from the conformity control unit 65. The conformity control unit 65 is mainly composed of a well-known microcomputer including a CPU 71 and a memory 72 having a ROM, RAM, rewritable EEPROM, and the like.

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

Further, when a request for writing the generated control constant to the memory 52 of the vehicle 1 (hereinafter, a write request) is input to the input receiving unit 61 by the operator, the conforming control unit 65 sends the conforming communication unit 62 to the vehicle 1.

The output instruction is output via. The output instruction is an instruction that requests the ECU 15 to output at least a control constant toward the matching device 60. In the present embodiment, the conforming control unit 65 outputs an instruction requesting the ECU 15 to output a control constant toward the conforming device 60 as an output instruction.

Further, the conformity control unit 65 is output from the ECU 15 of the vehicle 1 in response to the conformity constant input to the input reception unit 61, the control constant generated according to the generation method based on the conformity constant, and the output instruction as described later. An image showing the control constant, the conformity constant, and the like is displayed on the conformity display unit 63.

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

In the present embodiment, the maximum allowable torque with respect to the engine speed is set as the first conformity constant A. The maximum allowable torque is a predetermined torque value for each range of engine speed, and is a torque value that can be output from the engine 12. The maximum allowable torque can be set to a different value depending on the country in which the vehicle 1 is shipped.

The maximum allowable torque as the first conformity 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, and P3 or more and less than P4, the allowable maximum torque corresponding to each is set to Q2, Q3, and Q4. It is assumed that each allowable maximum torque is set to Q1 <Q2 <Q3 <Q4.

Further, in the present embodiment, the maximum component protection torque is set as the second conformity constant B. The component protection maximum torque is a torque value set so that the load applied to the mechanical component, the electric component, or the like used to output the torque does not exceed the allowable magnitude of the component. The component protection torque may be a value different depending on the type and grade of the vehicle 1.

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

As a result, in the present embodiment, the smaller value of the first conformity constant A and the second conformity constant B is set as the control constant X.
For example, it is assumed that the worker inputs the above-mentioned first conformity constant A and the value R as the second conformity constant B to the conforming device 60. Here, Q2 <R <Q3.

In this case, in the matching device 60, when the engine speed is less than P1, Q1 is calculated as the control constant X. When the engine speed is P1 or more and less than P2, Q2 is calculated as the control constant X. If the engine speed is P2 or more and less than P3, or P3 or more and less than P4, R is calculated as the control constant X.

For example, the operator performs adaptation while monitoring whether or not the engine 12 is properly controlled so that the torque output from the engine 12 is not insufficient in the vehicle 1. That is, the operator monitors each engine speed while appropriately changing the value of the allowable maximum torque as the first conformity constant A or the component protection maximum torque as the second conformity constant B.

As described above, the matching constant for calculating the control constant may be one or more. Further, the conformity constant may be 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 S130, the ECU 15 records in the EEPROM 55 the content instructed to be recorded in the recording instruction. That is, the ECU 15 associates the control constants acquired in S120 with the conformity constants and records them in the EEPROM 55. Then, the conformity recording process is completed. For example, the ECU 15 records the control constant X, the first conformity constant A, and the second conformance constant B in the EEPROM 55 in association with each other.

As a result, the control constants are recorded in the ECU 15, and the conforming constants used to generate the control constants are also recorded in the ECU 15.
[1-2-2. Conformity output processing]
Next, the matching output process executed by the ECU 15 when the ECU 15 is connected to the matching device 60 will be described with reference to the flowchart of FIG.

In S230, the ECU 15 outputs the control constant and the conforming constant acquired from the EEPROM 55 in S220 to the conforming device 60. Then, this conforming output processing is terminated. For example, the ECU 15 outputs the control constant X, the first conformity constant A, and the second conformance constant B to the conforming device 60.

[1-2-3. Operation]
The ECU 15 configured in this way is communicably connected to the matching device 60 when the fitting is performed by the operator, and operates as follows.

The conforming operator inputs a read request to the conforming device 60 as shown in FIG. Then, an output instruction is output from the matching device 60 to the ECU 15.
The ECU 15 outputs the control constant instructed by the output instruction 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 conforming device 60, an image showing the control constant and the conforming constant recorded in the ECU 15 is displayed on the conforming display unit 63.

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

The operator causes the vehicle 1 to perform control using the generated control constants, and determines whether or not the control based on the control constants is appropriately performed in the vehicle 1. That is, the operator appropriately inputs a plurality of types of conforming constants to the conforming device 60, causes the conforming device 60 to output a recording instruction each time the conforming constant is input, and causes the ECU 15 to write the control constant and the conforming constant. , The conforming is terminated when the most appropriate control result is obtained in the vehicle 1.

As a result, the EEPROM 55 included in the ECU 15 records the control constant when the most appropriate control result is obtained and the conforming constant for generating the control constant.
The control constant set to the optimum value by the conformity can be adjusted again in response to, for example, improvement of the performance of the vehicle or a 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 rematching, the operator can make the matching device 60 output an output instruction and acquire the control constants already recorded in the EEPROM 55 included in the vehicle 1 together with the matching constants. That is, the operator can perform refitting while referring to the control constant and the fitting constant at the time of the previous fitting.

[1-3. effect]
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 acquires a recording instruction, which is an instruction for recording at least a control constant and a conforming constant, from the conforming device 60. In S130, the ECU 15 records at least the control constant and the conformity constant in the EEPROM 55 in association with each other. The conforming device 60 is a device outside the vehicle, is communicably connected to the ECU 15, generates a control constant according to a predetermined generation method using the conforming constant, and is configured to output a recording instruction. ing. The control constant is a value for performing predetermined control in the vehicle. The conforming constant is a value input to the conforming device 60. The EEPROM 55 is a rewritable memory mounted on the vehicle.

According to this, the operator can perform the fitting while appropriately referring to the fitting constant recorded in the EEPROM 55. For this reason, the vehicle is controlled more than the conventional ECU in which the control constant is only recorded but the conformity constant is not recorded, that is, it is difficult to guess the conformity constant for generating the control constant. The control constant for this can be easily set based on the matching constant.

Further, when reconforming the control constant, the operator appropriately sets the conforming constant recorded in the EEPROM 55, for example, setting a value near the conforming constant recorded in the EEPROM 55 as a new conformity constant. While referring to it, it is possible to efficiently reset the control constant based on the conforming constant.

As a result, the operator can easily set the control constant based on the conformity constant while referring to the acquired control constant and the conformity constant.

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

In the first embodiment described above, the ECU 15 records the control constant and the conformity 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 conformity constant, and the generation method are associated and recorded in the EEPROM 55.

[2-2. processing]
[2-2-1. Conformity 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.

The ECU 15 acquires a recording instruction in S110. In the present embodiment, the recording instruction is an instruction to record the control constant, the conforming constant, and the generation method in the EEPROM 55. That is, the recording instruction includes a control constant, a conforming constant, a generation method, and an instruction to record these in the EEPROM 55.

In S121, the ECU 15 acquires the control constant, the conformity constant, and the generation method included in the recording instruction from the recording instruction.
The ECU 15 acquires a comparison value in S123. The comparison value is a value generated according to the generation method instructed by the recording instruction by using the conforming constant indicated by the recording instruction received by the ECU 15. The comparison value is generated by the ECU 15 by a process other than the present 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 and the comparison value match. 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 in the EEPROM 55 the content instructed to be recorded by the recording instruction in S130, which shifts when the instructed control constant and the comparison value match. That is, the ECU 15 causes the EEPROM 55 to record the conformity constant, the control constant, and the generation method instructed by the recording instruction in association with each other. Then, the ECU 15 ends the conformity recording process.

[2-2-2. Conformity output processing]
Next, the conforming output processing in the present embodiment executed by the ECU 15 of the second embodiment in place of the conforming output processing of the first embodiment will be described with reference to the flowchart of FIG. Since the processing of S210 in FIG. 7 is almost the same as the processing of S210 in FIG. 4, the description is partially simplified.

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

In S235, the ECU 15 outputs the control constant, the conforming constant, and the generation method acquired from the EEPROM 55 in S225 to the conforming device 60. Then, this conforming output processing is terminated.

According to this, since the conformity constant and the generation method are recorded in the EEPROM 55 together with the control constant, even if the generation method is not recorded in the conforming device 60, the generation method recorded in the EEPROM 55 is acquired. It is possible to perform conformity 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 conformity constant instructed by the recording instruction. In S125, the ECU 15 determines whether or not the control constant instructed by the recording instruction and the comparison value match. In S130, the ECU 15 causes the EEPROM 55 to record when it is determined by S125 that they match.

According to this, when the control constant included in the recording instruction and the comparison value match, the ECU 15 transmits and receives the recording instruction without a communication error in the communication path between the ECU 15 and the matching device 60. It becomes possible to judge. Further, the ECU 15 records the control constant, the conformity constant, and the generation method in the EEPROM 55 when they match, so that the ECU 15 records the control constant, the conforming constant, and the generation method in the EEPROM 55 after confirming that no communication error has occurred in the communication path. Is possible.

The ECU 15 may record at least the control constant and the conformity constant in the EEPROM 55 in association with each other.
(2c) In S210, the ECU 15 acquires an output instruction from the conforming device 60, which is an instruction to output at least a control constant to the conforming device 60.
