Specifically, the engine core controller has different control scenes, different control methods and different data structures, and is more complex to control, so the control methods of the core controller are all customized development at present, and no platform is considered. Therefore, the control method of the vehicle engine provided by the invention has the advantages that the control methods of engine core components such as oil injection, ignition and oil pump are subjected to information collection and induction summary, the data structures of actuators such as oil injection, ignition and oil pump are subjected to abstract and platform design, a set of control logic is used for completing effective control of the oil injection, ignition and oil pump, the control logic and control data are stripped, and the control adaptation of different engines can be completed rapidly through the configuration of oil injection, ignition and oil pump data, so that the degree of multiplexing and the flexibility of transplanting of codes are improved, the stability of the control method is greatly improved, the test workload in the adaptation process of different engines is reduced, the transplanting time of the engine control method is greatly shortened, and the quality of the control method is also effectively ensured.
Specifically, the control of the core controllers such as the fuel injector, the ignition coil, the high-pressure oil pump and the like is based on the control of the starting working angle, the continuous working time length and the ending working angle of the actuator, and the above processes are reflected on the output of the engine controller or the control algorithm, and then the control of a single pulse signal (the following control is called PLUSE control for short). By generalizing the current PULSE control method, as shown in fig. 2, fig. 2 is a schematic diagram of a single PULSE control mode, and 7 control modes are divided:
Mode 1: tb (Time begin) is the start Time, te (Time end) is the end Time, and Am (Angle max) is the maximum Angle. This mode is abbreviated as TT-A (TimeTime-Angle) control mode, i.e. the start point of the PULSE is controlled with the time parameter Tb, the end point is controlled with the time parameter Te, and the protection point is controlled with the Angle parameter Am;
Mode 2: a control mode abbreviated as AA-T (ANGLEANGLE-Time), in which Ab (Angle begin) is a start Angle, ae (Angle end) is an end Angle, and Tm (Time max) is a maximum Time.
Mode 3: ab (Angle begin) is the start Angle, pw (Pulse width) is the duration, and Am (Angle max) is the maximum Angle. This mode is simply referred to as an AP-a (Angle-Pulsewidth) control mode, i.e. the start point of the PULSE is controlled with the Angle parameter Ab, the PULSE width is controlled with the time parameter Pw, and the guard point is controlled with the Angle parameter Am.
Mode 4: this mode is simply referred to as an a-PA-T (Angle-PulsewidthAngle-Time) mode, in which the start point of the PULSE is controlled using an Angle parameter Ab (Ab needs to be converted from the Angle parameter Ae, the PULSE width parameter Pw, the current average engine speed n), the end point is controlled using the Angle parameter Ae, and the guard point is controlled using the Time parameter Tm.
Mode 5: a short T-PA-T mode;
Mode 6: a mode called a-PA-A for short;
mode 7: abbreviated as T-PA-A mode.
And for the 7 control modes, the modes of parameter setting are shown in table 1, and table 1 is a parameter setting mode table of 7 PULSE control modes:
table 17 parameter set pattern table of PULSE control patterns
The corresponding PULSE DATA structure (hereinafter PUL-DATA) is constructed as follows: pulseEnable (Pulse control enabled, flag if this Pulse is performed), pulseMode (Pulse control mode), STARTANGLE (start angle), startTime (start time), stopAngle (end angle), stopTime (end time), DWELLANGLE (Pulse duration angle), DWELLTIME (Pulse duration time), protectAngle (guard angle), protectTime (guard time), INTERVALTIME (minimum time interval between PULSEs, in order to reserve execution time for the actuator), pusleState (Pulse state, divided into in-computation, in-load, in-execution, end etc. states), irqMask (interrupt flag word, pulse start point, end point, guard point can be marked respectively, if the flag bit is set, an interrupt event is generated at the corresponding Pulse point, informing the controller to perform subsequent processing).
Aiming at the control of an oil injector, an ignition coil and a high-pressure oil pump, more complex scenes exist, for example, in order to meet the requirements of power performance and oil consumption, a common vehicle factory also has a control method of multiple oil injection, and 7 PULSE outputs can be continuously controlled under the maximum condition; a high pressure oil pump follows the multiple TT-A mode PULSEs after the primary PULSE output. The above-described sequentially outputted plurality of PULSEs are combined into patten. That is, one patterm contains a plurality of PULSEs. As shown in fig. 3, fig. 3 is a conceptual diagram of patterm and PULSE. When one patten contains 3 PULSEs, denoted as PULSE1, PULSE2, and PULSE3, respectively, the corresponding DATA structure of the patten (hereinafter referred to as PAT-DATA) is constructed as follows: reserved (reserved words for controlling scene expansion), pulseNumber (number of PULSEs contained in PATTERN), PATTERNSTATE (PATTERN state, divided into in-compute, in-load, in-execution, end, etc. states), patternEnable (PATTERN control enabled, marking whether this PATTERN is executed), PUL-DATA1, PUL-DATA2 … …, PUL-DATAn (n equals pulseNumber).
In the embodiment of the invention, layering and modularization design are adopted for controlling the oil injection, ignition and oil pump, the whole frame is shown in fig. 4, fig. 4 is a schematic diagram of the control frame of the oil injection, ignition and oil pump, and a small box represents a PAT-DATA. The three boxes in the first layer in fig. 4 sequentially represent an oil injection data interface, an ignition data interface and an oil pump data interface, the upper small boxes in the second layer form an acquired oil injection data set, the middle small boxes form an acquired ignition data set, the lower small boxes form an acquired oil pump data set, the three independent boxes in the third layer sequentially verify the acquired oil injection data set, the ignition data set and the oil pump data set, the three independent boxes in the fourth layer correspond to the third layer one by one, and the original data (oil injection data set, oil pump data set and oil pump data set) are sequentially verified according to the verification result, Ignition data set, oil pump data set), and the newly set fuel injection data, ignition data, and oil pump data are obtained. In the control process of carrying out the platformization, as shown in fig. 5, the fuel injection DATA interface acquires detailed fuel injection DATA from the application layer interface, corresponds to "acquire fuel injection DATA" in fig. 5, carries out the processes of checking the PATTERN effective area, checking the PATTERN DATA conflict, and the like on the fuel injection PATTERN DATA, corresponds to "PATTERN check" in fig. 5, writes the processed DATA into the PAT-DATA area of the fuel injection, then carries out the checks of the maximum value, the minimum interval, and the like of the fuel injection PULSEs, corresponds to "single PULSE check" in fig. 5, further carries out the adjustment on the original fuel injection PULSEs according to the check result, corresponding to the single PULSE adjustment in fig. 5, the range check is performed on the new patterm 1 data formed by the new fuel injection PULSE after adjustment, corresponding to the 'patterm range check' in fig. 5, further, according to the range check result, the multiple checks such as data overlap check and conflict check between different cylinders are performed on the new adjusted patterm 2 data, corresponding to the 'multiple patterm check' in fig. 5, the check result is obtained, meanwhile, the relative angle corresponding to the check result is converted into an absolute angle, the post-processing of the data is facilitated, corresponding to the 'relative absolute conversion' in fig. 5, and then the processed data is subjected to data programming by comparing with the seven pulse control modes, corresponding to the data programming in the figure 5, so that the programming result is written into a time timer and an angle counter in hardware, pulse output is performed through set level logic, corresponding to the data execution in the figure 5, further, the execution result is subjected to terminal feedback, corresponding to the execution state feedback in the figure 5, and the platform control of the oil injection data is completed. The processed data is written into an angle counter and a time timer in the hardware, and the final PUSLE control is completed by the hardware. Control of ignition data, control of oil pump data and processing logic of oil injection are kept consistent: for the control of the ignition DATA, the ignition DATA interface acquires detailed ignition DATA from the application layer interface, performs the processes of PATTERN effective area verification, PATTERN DATA conflict verification and the like on the ignition PATTERN DATA, writes the processed DATA into the ignition PAT-DATA area, then performs the verification of the maximum value, the minimum interval and the like of the ignition PULSE, writes the processed DATA into an angle counter and a time timer in hardware, and completes the final PUSLE control by the hardware; for the control of oil pump DATA, the oil pump DATA interface acquires detailed oil pump DATA from the application layer interface, after the PATTERN effective area verification, PATTERN DATA conflict verification and the like are carried out on the oil pump PATTERN DATA, the processed DATA are written into the PAT-DATA area of the oil pump, then the verification of the maximum value, the minimum interval and the like of the oil pump pulsE is carried out, the processed DATA are written into an angle counter and a time timer in hardware, and the final PUSLE control is completed by the hardware.
It should be noted that, not all vehicle engines have both fuel injectors and ignition coils, and an exemplary diesel engine does not have ignition, a natural gas engine does not have fuel injection, and the data structures of fuel injection and ignition of the same vehicle may be different, so that the fuel injection data interface, and the fuel pump data interface are different interfaces, different starting modes exist for the engines of different vehicles, for diesel engines, no ignition coil control exists, the engine control can be performed by controlling the fuel injector and the high-pressure fuel pump, and for naturally aspirated engines, no high-pressure fuel pump exists, the engine control is performed by controlling the ignition coil and the fuel injection valve (similar to the fuel injector), wherein the above-mentioned preset data interfaces are in one-to-one correspondence with each core executor, and exemplary data acquisition of the fuel injector can be performed by the fuel injection data interface, data acquisition of the ignition coil can be performed by the ignition data interface, data acquisition of the high-pressure fuel pump can be performed by the fuel pump data interface, and the fuel injection data interface, the fuel injection data interface and the fuel pump data interface can all be obtained by the application layer interface, that is the control the fuel injection data interface, and the fuel pump data interface can be obtained by the application layer interface. Because the oil injection DATA interface, the ignition DATA interface and the oil pump DATA interface of the application layer are inconsistent, the main function of the DATA acquisition module is to reconstruct the acquired DATA according to the PAT-DATA DATA structure. The above raw data can be understood as raw data of fuel injection, ignition, oil pump, etc. acquired through interfaces of the core actuators, and if the engine is controlled by using the raw data, the engine must be checked. Therefore, the collected original data can be verified through preset rules.
Specifically, when the original data is verified, it is required to be clear that the original data corresponding to each cylinder of the target vehicle engine includes a plurality of preset unit data, where the plurality of preset unit data may be understood as patterm data corresponding to each cylinder, where the patterm data corresponds to the number of cylinders of the vehicle one by one, and a single patterm includes a plurality of pulse data as shown in fig. 3 above. Specifically, the preset rules may be subdivided into a first preset rule and a second preset rule, where the first preset rule may be understood to be used for defining a first pattern check, and only includes validity check of the same cylinder, and the second preset rule may be understood to be used for defining pattern check between different cylinders of the same vehicle engine. When the first preset rule is utilized to carry out validity check on the original data such as oil injection, ignition, oil pump and the like of the same cylinder, the original data of the ignition coil can be subjected to validity check on the operation speed of the oil pump by means of an example, and the like, the actual check result of each original data can be compared with a preset check threshold value by means of the comparison, the first check result can be optimally analyzed, namely, the first check result comprises an example ignition time check result, an oil pump operation speed check result and the like, the original data can be adjusted by means of the preset check threshold value, so that a plurality of first preset unit data can be obtained, the example can be adjusted by means of the preset check threshold value, if the preset check threshold value is displayed, the preset ignition time threshold value is a threshold value of 1-2 seconds, if the actual ignition time check result exceeds the preset ignition time threshold value, the first preset unit data can be compared, and the first preset unit data can comprise the first adjusted ignition time, and the first preset unit data can be represented by the pulse data, the first preset data can be represented by the pulse check result, the second data can be represented by the pulse data, and the pulse data can be represented by the pulse check result, and the data can be represented by the pulse data.
Specifically, when the initial verification result is utilized to adjust the original data to obtain a plurality of first preset unit data, specifically, the initial verification result, that is, the result of performing the initial verification on the pattern may be utilized to adjust the original data, and the obtained plurality of initial preset unit data may be characterized as pattern1 obtained after performing the initial validity verification on the original pattern, and further, the preset time rule may be utilized to verify the plurality of pulse data in pattern1, where the preset time rule may be understood as including verifying the maximum time, the minimum time and the minimum interval time of a single pulse, and may obtain a verified time verification result, and further, each pulse data in the initial pattern may be adjusted by utilizing the obtained time verification result, so that the adjusted pulse data accords with the preset time rule, and then the first preset unit data may be understood as pulse data in pattern1 is adjusted, and then updated pattern2 is obtained.
Through the steps, the data of the oil injection, the ignition and the oil pump of the vehicle engine can be accurately checked, so that the control state of the engine is ensured to be optimal.
Further, step S1043 includes:
Checking a plurality of first preset unit data according to a first preset rule to obtain a third checking result;
Adjusting the first preset unit data according to the third verification result to obtain second preset unit data;
Checking the second preset unit data according to a preset conflict rule in the second preset rule to obtain a fourth checking result, wherein the preset conflict rule in the second preset rule is used for representing the correct operation sequence of a plurality of cylinders of the target vehicle engine in the engine operation process;
Checking the second preset unit data according to a preset overlap rule in the second preset rule to obtain a fifth checking result, wherein the preset overlap rule is used for representing an instruction that a plurality of cylinders of the target vehicle engine are forbidden to be executed between different cylinders in the running process of the engine;
and obtaining a verification result according to the fourth verification result and the fifth verification result.
Specifically, as shown in fig. 5, when any pulse data in the pattern data is verified by using the second preset rule, the second pattern verification is defined, including validity verification and conflict verification and overlap verification between different cylinders. Specifically, first, the validity of the pattern2 formed by the new pulse data set may be verified by using a first preset rule, that is, by using the validity verification of the same cylinder, then the third verification result may be characterized as a result obtained by performing validity verification on the pattern2, and by adjusting the pulse data in the pattern2, which does not reach the preset threshold, in the verification result, a plurality of second preset unit data may be obtained, and then the second preset unit data may be characterized as a pattern3 formed by performing adjustment on the pulse data in the pattern2 and then obtaining a new pulse data set. Since the actuator motion and engine phase are very closely related (e.g., injector opening is typically in the intake stroke, ignition coil opening time is typically near compression top dead center), fuel injection, ignition, and oil pump control are typically set to a useful range. The PAT-DATA valid range check is to ensure that the DATA falls within the valid range. For data beyond the effective range, pulse phase or pulse displacement operation is performed according to the configured processing strategy.
More specifically, after the validity check is performed using the first preset rule, the conflict check and the overlap check between different cylinders may be performed using the second preset rule. The overlapping verification can be interpreted as that when the oil injection signals of two cylinders are received simultaneously, signal overlapping occurs, so that hardware cannot determine which cylinder is injected under the overlapping condition; the conflict check may be interpreted as that when the injection sequence of the cylinder is set to 1342 for sequential injection, but the actual injection sequence does not coincide with the set sequence, and a conflict is generated, that is, the above-mentioned conflict check. And carrying out conflict verification on the adjusted pattern3 by utilizing a preset conflict rule to obtain a fourth verification result, wherein the fourth verification result can be characterized as a result obtained by carrying out conflict verification on the pattern3, and the preset conflict rule can be characterized as a correct running sequence of a plurality of cylinders of the target vehicle engine in the running process of the engine. Meanwhile, the adjusted pattern3 is subjected to overlap verification by using a preset overlap rule, so that a fifth verification result can be obtained, the fifth verification result can be characterized as a result obtained by carrying out overlap verification on the pattern3, and the preset overlap rule can be characterized as an instruction that a plurality of cylinders of the target vehicle engine are forbidden to be executed simultaneously among different cylinders in the running process of the engine, namely, the instruction execution needs to be carried out among different cylinders of the engine according to a set sequence. And combining the result obtained by performing conflict verification on the pattern3 and the result obtained by performing overlap verification to obtain the verification result, namely the result obtained after performing the second pattern verification.
Step S106, adjusting the original data based on the verification result to obtain target data;
And S108, controlling target equipment corresponding to each cylinder to execute target data, and obtaining an execution result of the target data.
Wherein, step S108 includes:
Step S1081, converting the angle information in the target data according to the preset position information to obtain the data to be executed;
step S1082, executing the data to be executed to obtain an execution result of the target data;
Step S1083, sending the execution result to the application layer of the target vehicle;
In step S1084, in response to receiving the operation instruction of the terminal, the execution result is transmitted from the application program of the target vehicle to the terminal.
Further, step S1082 includes:
Writing data to be executed into target hardware of a target vehicle according to a preset pulse control mode, wherein the target hardware comprises a time timer and an angle counter;
The target hardware outputs an electric signal corresponding to the target data according to the written target data;
in the process of outputting the electric signal corresponding to the target data, an execution result is generated according to the flag word in the preset pulse control mode.
Specifically, as shown in fig. 5, after performing pattern verification on the original data twice, the original data may be adjusted according to the final verification result, where the target data is a data set that satisfies each preset verification value after adjustment, and then the target device corresponding to each cylinder is controlled to execute the target data, so as to obtain an execution result of the target data, that is, the fuel injection device, the ignition device and the oil pump device corresponding to each cylinder of the vehicle engine execute corresponding data, so as to ensure that the engine is started normally. Specifically, when each device executes the above data, for convenience of processing the data, the above data process generally uses a phase angle for processing, for example, 90 ° generally represents a 90 ° advance relative to the compression top dead center. But the data needs to be converted to absolute angles before it is actually executed. The relative absolute conversion is to convert all the above relative angles into absolute angles, and for an engine, the corresponding angle is 360×2=720, divided into 7200 parts, and each part is 0.1 degree, for example, in one engine working cycle. Assuming that the crankshaft tooth missing position is selected to be absolute 0 degrees (the absolute 0 degrees of the engine can be manually selected through a configuration file), an absolute angle system can be established. The data to be executed is the data which is subjected to relative absolute conversion and needs to be executed by each device, the execution result is further sent to an application layer of the target vehicle, and the execution result is fed back to the terminal by using an application program of the target vehicle.
More specifically, during the process of executing the data to be executed, the data to be executed may be written into target hardware of the target vehicle according to a preset pulse control mode, where the target hardware includes a time counter and an angle counter, in other words, the data to be executed is written into the time counter and the angle counter in the hardware, when the corresponding time point or the angle point arrives, the hardware outputs corresponding high level and low level on corresponding pins according to a set level output logic, so as to complete the output of the pulse. And triggering corresponding interruption when the pulse starting point, the pulse ending point or the pulse protecting point time occurs by hardware according to irqMask set by pattern, and notifying an application layer to perform corresponding data processing such as pulse state, pulse count and the like. irqMask (interrupt flag word, which can respectively flag the start point, the end point and the protection point of the PULSE, if the flag bit is set, an interrupt event is generated at the corresponding PULSE point, and the controller is notified to perform subsequent processing). The preset pulse control modes are the 7 pulse control modes shown in fig. 2.
Through the steps, the code multiplexing degree and the flexibility of transplanting are improved, the stability of the control method is greatly improved, and the control state of the engine is ensured to be optimal.
