Detailed Description
The present invention will be described in further detail with reference to the accompanying drawings and examples. It is to be understood that the specific embodiments described herein are merely illustrative of the invention and are not limiting of the invention. It should be further noted that, for the convenience of description, only some of the structures related to the present invention are shown in the drawings, not all of the structures.
Example one
Fig. 1 is a flowchart of a method for configuring a drive of an electronic control unit according to an embodiment of the present invention, where the present embodiment is applicable to configuring a drive of any electronic control unit on a vehicle, and the method can be implemented by a device for configuring a drive of an electronic control unit according to an embodiment of the present invention, and the device can be implemented by software and/or hardware and is integrated into an electronic device for implementing the method.
Specifically, referring to fig. 1, the method specifically includes the following steps:
and S110, searching a drive configuration item of the electric control unit to be driven in a predefined configuration mapping layer according to the hardware type of the electric control unit to be driven.
The configuration mapping layer maintains the mapping relation between the hardware type of each electric control unit and the drive configuration items.
Optionally, in the automotive electronic controller conforming to the automotive architecture, the MCAL is an abstraction of underlying hardware, and to implement driving of the ECU, first, the drive configuration parameters of the ECU are acquired, where the drive configuration parameters of the ECU are related to the hardware type of the ECU, and when the hardware types of the ECU are different, the drive configurations supported by the ECU are also different, so that the drive configuration parameters of the ECU are also different. Therefore, when a certain ECU is driven, the hardware type of the ECU to be driven needs to be determined, wherein the hardware type of the ECU to be driven may be: the identification of the ECU to be driven with different driving configuration requirements of the MCAL layer caused by vehicle model adaptation requirements or hardware differences indicates the hardware type of the ECU to be driven by defining a global variable or a standard quantity, and can identify which ECU to be driven at this time according to the information in the global variable or the standard quantity. After the to-be-driven ECU is identified, the drive configuration item of the to-be-driven ECU can be searched in a configuration mapping layer, wherein the drive configuration of the ECU is realized in an MCAL layer, the specific structure of the MCAL layer can be divided into three layers of architectures, namely an MCAL interface layer, a configuration mapping layer and an MCAL drive layer, the MCAL interface layer is mainly used for receiving interface calling information of the to-be-driven ECU, the configuration mapping layer is mainly used for maintaining the mapping relationship between the hardware type of each ECU and the drive configuration item, and the MCAL drive layer is mainly used for realizing the drive of the to-be-driven ECU.
In order to set multiple drive configurations in each electronic control unit, this embodiment additionally sets a configuration mapping layer in the MCAL layer, where a mapping relationship between the hardware type of each ECU and a drive configuration item is maintained, and the drive configuration item may integrate multiple types of configuration parameters, that is, the drive configuration item may be a configuration set name formed by combining multiple types of configuration parameters, and the like.
Specifically, a configuration mapping table may be designed in advance in the configuration mapping layer, where the configuration mapping table includes drive configuration items corresponding to hardware types of the ECUs under different configuration requirements of the MCAL layer, that is, a corresponding mapping relationship exists between the hardware type of each ECU and the drive configuration item in the configuration mapping table, so that the drive configuration item of the ECU to be driven may be found in the configuration mapping table of the configuration mapping layer according to the hardware type of the ECU to be driven, and the drive configuration item may have one or more types, which facilitates subsequent control of the ECU to be driven to perform driving operation.
Optionally, in order to accurately determine the to-be-driven ECU which needs to be driven at this time, before searching for the driving configuration item of the to-be-driven electronic control unit in the predefined configuration mapping layer in this embodiment, the method may further include: and receiving a driving instruction of the electric control unit to be driven.
And the driving instruction carries the hardware type of the electric control unit to be driven.
Specifically, the driving instruction of the to-be-driven ECU refers to a command for driving the to-be-driven ECU, and the driving instruction carries the hardware type of the to-be-driven ECU. After receiving the driving command, some preparation work is performed for the driving of the to-be-driven ECU, for example, the driving configuration item of the to-be-driven ECU is searched. The drive command carries the hardware type of the ECU to be driven, so that the ECU can be known to be driven according to the hardware type, and the smooth process of subsequently searching the drive configuration item of the ECU to be driven is ensured.
And S120, controlling the electric control unit to be driven to drive by adopting the configuration parameters under the drive configuration item.
The configuration parameters in the drive configuration item refer to parameters that the to-be-driven ECU needs to be configured in the corresponding drive configuration item, and may be, for example, a used channel, a channel type, an initial level, a default period, a duty ratio, and the like.
Specifically, after the drive configuration item of the ECU to be driven is found, the drive configuration item corresponding to the ECU to be driven is known, the configuration parameters under the drive configuration item of the ECU to be driven are used as the drive parameters of the ECU to be driven, and the specific drive process is set by the configuration parameters under the drive configuration item, so that the ECU to be driven can be controlled to be driven.
For example, in the present embodiment, the controlling the to-be-driven ECU to drive may be controlling the to-be-driven ECU to initialize, and a specific process is as follows:
1) acquiring the hardware type of an ECU to be driven;
2) calling an initialization interface of an MCAL interface layer;
3) according to the hardware type of the ECU to be driven, searching a drive configuration item of the ECU to be driven in a predefined configuration mapping layer, wherein the drive configuration item can comprise a general configuration item and an individual configuration item;
4) configuring a general configuration item of an ECU to be driven;
5) judging whether the ECU to be driven has an individual configuration item, if so, initializing after configuring the individual configuration item of the ECU to be driven, and if not, initializing;
6) and finishing the driving of the ECU to be driven, namely finishing the initialization of the ECU to be driven.
For example, a driving configuration manner of the ECU to be driven is described with an example of a configuration of Aurix TC297 PWM in MCAL. In this example, it is assumed that there are two types of hardware of the to-be-driven ECU, i.e., the to-be-driven ECU1 and the to-be-driven ECU2, and the PWM channel 0 and the PWM channel 1 are drive configuration items required by both of the to-be-driven ECUs, so that the PWM channel 0 and the PWM channel 1 are used as general configuration items, and the PWM channel 2 is a drive configuration item required only by the to-be-driven ECU2, so that the PWM channel 2 is used as a separate configuration item of the to-be-driven ECU 2. After configuration is completed, firstly, which ECU needs to be driven currently is judged through a predefined global variable or a predefined standard quantity, then a Pwm _17_ Gtm _ Init () interface is called to carry out initialization of Pwm, the hardware type of the ECU to be driven is mapped to a corresponding drive configuration item, and if the ECU is the ECU1, only a general configuration item needs to be initialized; if the configuration is the ECU2, the configuration is mapped to the general configuration item and the single configuration item CONFIG _ A configuration, then the general configuration item is initialized, then the single configuration item CONFIG _ A is initialized, and the initialization of the corresponding PWM is completed.
The following code is the configuration process of the individual configuration items of the ECU 2:
v. PWM channel 2
If(MCAL_CONFIG＝＝CONFIG_A)
#ifndef Pwm_17_GtmConf_PwmChannel_Pwm_P20_11
#define Pwm_17_GtmConf_PwmChannel_Pwm_P20_11((Pwm_17_ChanneType)2)
#endif
According to the technical scheme provided by the embodiment, firstly, the drive configuration items of the electric control units to be driven are searched in a predefined configuration mapping layer according to the hardware types of the electric control units to be driven, and the mapping relation between the hardware types of the electric control units and the drive configuration items is maintained in the configuration mapping layer, so that the decoupling mapping between each electric control unit and various drive configuration items is realized on the configuration mapping layer, the problem that various drive configurations of an ECU (electronic control unit) cannot be realized in the same configuration project is solved, the maintenance cost of the drive configurations of the electric control units is reduced, and the maintainability and the independence of the drive configurations of the electric control units are improved; and then, the configuration parameters under the drive configuration item are adopted to control the electric control unit to be driven to drive, so that the complexity of the electric control unit in the process of additionally carrying out drive configuration before driving is avoided, and the drive efficiency of the electric control unit is improved.
Example two
Fig. 2 is a flowchart of a driving configuration method of an electronic control unit according to a second embodiment of the present invention, which is optimized based on the second embodiment of the present invention. Optionally, this embodiment explains the recording process of configuring the mapping layer in detail.
Specifically, referring to fig. 2, the method of this embodiment may specifically include:
and S210, acquiring a drive configuration code of the electric control unit.
The drive configuration code of the electronic control unit is a section of code containing the mapping relation between the ECU and the drive configuration items of the ECU, and is written by developers according to the specific configuration requirements of each ECU. Therefore, when driving configuration is performed on each ECU, it is first necessary to acquire a driving configuration code of the ECU, and then, by analyzing specific contents configured in the driving configuration code of the ECU, a mapping relationship between each ECU and a driving configuration item is recorded in a configuration mapping layer.
Optionally, the driver configuration code name of the ECU may be searched in the code file by a predefined code name, so as to obtain the driver configuration code of the ECU, or the driver configuration code of each ECU may be stored in a corresponding folder, and the driver configuration code of the ECU may be obtained by searching a related folder. There are many methods of acquiring the drive configuration code of the ECU, and the embodiment is not particularly limited.
S220, analyzing the mapping relation between each electric control unit configured in the drive configuration code and the drive configuration item of the electric control unit, and recording the mapping relation into the configuration mapping layer.
Specifically, after the drive configuration code of the ECU is obtained, since the drive configuration code of the ECU includes the mapping relationship between the ECU and the drive configuration items of the ECU, the specific configuration content for each electronic control unit in the drive configuration code can be analyzed by running the drive configuration code, and the mapping relationship between each ECU and the drive configuration items of the ECU can be obtained through the specific configuration content. For example, by analyzing the mapping relationship between each ECU configured in the drive configuration code and the drive configuration item of the ECU, it can be found that the drive configuration item corresponding to the ECU1 and the ECU2 is configuration a, the drive configuration item corresponding to the ECU3 is configuration B, and so on. After each ECU and the drive configuration items of the ECU are acquired, the mapping relationship between each ECU and the drive configuration items of the ECU can be recorded in a configuration mapping layer, so that the mapping relationship between the ECU and the drive configuration items of the ECU can be maintained conveniently.
Optionally, the recording to the configuration mapping layer may specifically include: and aiming at each electric control unit in the drive configuration codes, searching a drive configuration space which is allocated for a drive configuration item of the electric control unit in advance in the configuration mapping layer, and adding the hardware type of the electric control unit into the drive configuration space.
Specifically, a configuration relationship table is maintained in the configuration mapping layer, and a mapping relationship between the hardware type of each ECU and the drive configuration item of the ECU is recorded in the configuration relationship table. The drive configuration space refers to a storage space allocated to each drive configuration item of the electronic control unit in the configuration relationship table, and may be named as a name of a corresponding drive configuration item, such as MCAL configuration a and MCAL configuration B. Since the drive configuration code may include a plurality of ECUs, for each ECU in the drive configuration code, it needs to search in the configuration mapping layer whether there is a drive configuration space allocated in advance for the drive configuration item of the ECU, and if the drive configuration space allocated in advance for the drive configuration item of the ECU is found in the configuration layer, the hardware type of the ECU belonging to the drive configuration space can be added to the drive configuration space according to the name of the corresponding drive configuration item. For example, if the drive configuration items corresponding to the ECU1 and the ECU2 are configuration a and the drive configuration item corresponding to the ECU3 is configuration B by analyzing the drive configuration codes, the corresponding drive configuration spaces, namely, MCAL configuration a drive configuration space and MCAL configuration B drive configuration space, are allocated to the configuration a and the configuration B in the configuration relationship table in the configuration mapping layer, so that the ECU1 and the ECU2 can be added to the MCAL configuration a drive configuration space, and the ECU3 can be added to the MCAL configuration B drive configuration space.
Optionally, finding out the driving configuration space pre-allocated for the driving configuration item of the electronic control unit in the configuration mapping layer may specifically include: if the configuration mapping layer does not have the drive configuration item of the electric control unit, additionally applying a new drive configuration space in the configuration mapping layer as the drive configuration space which is allocated for the drive configuration item of the electric control unit in advance in the configuration mapping layer.
Specifically, the configuration relationship table in the configuration mapping layer records the mapping relationship between the hardware type of each ECU and the drive configuration item of the ECU, but if the drive configuration item of an ECU cannot be found in the configuration relationship table, it represents that the drive configuration item is not recorded in the configuration relationship table, and the drive configuration item may be a newly added drive configuration item, a new drive configuration space is additionally applied in the configuration relationship table in the configuration mapping layer as the drive configuration space pre-allocated for the drive configuration item of the ECU in the configuration mapping layer, and then the hardware type of the ECU can be added to the new drive configuration space.
Optionally, if the hardware type of a certain ECU does not need to be maintained, the hardware type of the ECU may be deleted in the corresponding drive configuration space in the configuration relation table, and if the hardware type of the ECU is deleted, it is found that there is no corresponding ECU hardware type in the drive configuration space, the hardware types of the ECU in the drive configuration space and the drive configuration space may be deleted at the same time, or the drive configuration space may be reserved for subsequent use.
In this embodiment, the mapping relationship between the hardware type of each ECU and the drive configuration item of the ECU can be conveniently and quickly recorded through the configuration relationship table maintained in the configuration mapping layer, so that the subsequent maintenance of the mapping relationship between the hardware type of each ECU and the drive configuration item of the ECU is facilitated.
And S230, searching a drive configuration item of the electric control unit to be driven in a predefined configuration mapping layer according to the hardware type of the electric control unit to be driven.
And S240, controlling the electric control unit to be driven to drive by adopting the configuration parameters under the drive configuration item.
According to the technical scheme provided by the embodiment, the drive configuration codes of the electric control units are firstly obtained, then the mapping relation between each electric control unit configured in the drive configuration codes and the drive configuration items of the electric control units is analyzed and recorded in the configuration mapping layer, so that decoupling mapping between each electric control unit and various drive configuration items is realized on the configuration mapping layer, the problem that various drive configurations of an ECU (electronic control unit) cannot be realized in the same configuration project is solved, the maintenance cost of the drive configuration of the electric control units is reduced, and the maintainability and the independence of the drive configuration of the electric control units are improved; and then, according to the hardware type of the electric control unit to be driven, searching a drive configuration item of the electric control unit to be driven in a predefined configuration mapping layer, and finally controlling the electric control unit to be driven to drive by adopting configuration parameters under the drive configuration item, so that the complexity of the electric control unit in the process of additionally carrying out drive configuration before driving is avoided, and the drive efficiency of the electric control unit is improved.
EXAMPLE III
Fig. 3 is a flowchart of a driving configuration method of an electronic control unit according to a third embodiment of the present invention, which is optimized based on the third embodiment of the present invention. Optionally, this embodiment explains the parsing process of the driver configuration code in detail.
Specifically, referring to fig. 3, the method of this embodiment may specifically include:
and S310, acquiring a drive configuration code of the electronic control unit.
S320, analyzing the mapping relation between each electric control unit configured in the drive configuration code and the drive configuration item of the electric control unit, and recording the mapping relation into the configuration mapping layer.
S330, analyzing the configuration parameters of each drive configuration item configured in the drive configuration code, and recording the configuration parameters into a preset configuration file.
The preset configuration file is a file for storing a drive configuration item of each to-be-driven ECU and configuration parameters under each drive configuration item.
Specifically, after the drive configuration code of the ECU is acquired, the specific configuration content for each electronic control unit in the drive configuration code can be analyzed by running the drive configuration code, and the drive configuration item of the ECU to be driven and the configuration parameters under each drive configuration item can be acquired through the specific configuration content. For example, it is possible to obtain values of configuration parameters such as the type, initial level, default period, duty ratio, and the like of a channel used in the MCAL layer in the drive configuration item and the configuration a as the drive configuration item of a certain ECU to be driven. After obtaining the values of the configuration parameters, the values of the configuration parameters can be recorded in a preset configuration file, so that the later maintenance and use are facilitated.
Optionally, the drive configuration code may obtain a drive configuration item and configuration parameters of the drive configuration item of the ECU to be driven in the current operation process each time the drive configuration code is operated, and when a new drive configuration item occurs, the new drive configuration item is added to the preset configuration file, a new storage space is added to the new drive configuration item in the preset configuration file, and the configuration parameters of the new drive configuration item are stored in the new storage space; if the drive configuration item of the to-be-driven ECU and the configuration parameters of the drive configuration item obtained in the current operation process already exist in the preset configuration file, the drive configuration item of the to-be-driven ECU and the configuration parameters of the drive configuration item obtained in the current operation process do not need to be recorded.
It should be noted that: s320 and S330 may be executed simultaneously or sequentially, and this embodiment is not limited in particular.
S340, according to the hardware type of the electric control unit to be driven, searching a drive configuration item of the electric control unit to be driven in a predefined configuration mapping layer.
And S350, searching configuration parameters under the drive configuration items of the electric control unit to be driven in the preset configuration file.
Specifically, since the configuration parameters of each drive configuration item are recorded in the preset configuration file, the drive configuration item of the ECU to be driven can be known according to the hardware type of the ECU to be driven, and then the configuration parameters under the drive configuration item of the ECU to be driven can be searched in the preset configuration file. After the configuration parameters under the drive configuration item of the to-be-driven ECU are found, the configuration parameters under the drive configuration item can be adopted to complete the subsequent operation of controlling the to-be-driven ECU to drive.
And S360, controlling the electric control unit to be driven to drive by adopting the configuration parameters under the drive configuration item.
According to the technical scheme provided by the embodiment, firstly, the drive configuration codes of the electric control units are obtained, the mapping relation between each electric control unit configured in the drive configuration codes and the drive configuration items of the electric control units is analyzed and recorded in the configuration mapping layer, so that decoupling mapping between each electric control unit and various drive configuration items is realized on the configuration mapping layer, the problem that multiple drive configurations of an ECU (electronic control unit) cannot be realized in the same configuration project is solved, the maintenance cost of the drive configuration of the electric control units is reduced, and the maintainability and the independence of the drive configuration of the electric control units are improved; and then analyzing the configuration parameters of each drive configuration item configured in the drive configuration code, recording the configuration parameters into a preset configuration file, searching the drive configuration item of the electric control unit to be driven in a predefined configuration mapping layer according to the hardware type of the electric control unit to be driven, searching the configuration parameters under the drive configuration item of the electric control unit to be driven in the preset configuration file, and finally adopting the configuration parameters under the drive configuration item to control the electric control unit to be driven to drive, thereby avoiding the complexity of additionally carrying out a drive configuration process before the electric control unit is driven, and improving the drive efficiency of the electric control unit.
