Background technique

As the basic tool of modern traffic operation, vehicles have increasingly become an indispensable part of modern people's travel and transportation. The safe and orderly operation of vehicles is a prerequisite for transportation efficiency and transportation safety. In order to ensure that the vehicle is in good operation and is safe, the vehicle must provide effective early warning before encountering a failure, and provide a certain system guarantee before the predicted failure occurs, so as to reduce the possibility of actual failures and dangerous accidents , the engine induction system is set up for the above purpose.

The operation of modern engines is controlled by the engine control unit, which collects signals and detects possible specific faults through certain algorithms. When getting a signal that a specific fault may occur or that a specific fault has occurred, the engine control unit sends an instruction to the engine induction system to notify the vehicle manager to perform maintenance or repair to eliminate the fault and reduce the possibility of real danger. Specific faults are predetermined by the vehicle designer based on experience or regulatory requirements. Generally, after the engine induction system is instructed, the timing module in it starts timing. If the vehicle is not effectively managed and the above faults are eliminated after the preset time, the induction system will output the induction result, and the engine control unit will tell the The operation of the engine is subject to certain restrictions, which include, but are not limited to, reducing the operating speed of the engine, reducing the torque of the engine, and providing uninterrupted warning information.

In order to give the vehicle manager enough time to take certain maintenance or repair measures, the time setting may be quite long after the induction system starts to operate and before the restriction measures are taken, which brings inconvenience to the effectiveness test of the engine induction system. Tests take a considerable amount of time to get test results.

Therefore, there is a need to provide techniques that can facilitate the availability of test results when testing the effectiveness of the induction system while ensuring that the induction system operates normally after testing.

Detailed ways

It should be understood that the drawings are only used to illustrate the present application. The natural timekeeping speed mentioned in this application is the running speed of natural time.

Please refer to FIG. 1 , which is a functional block diagram of an embodiment of an engine induction system of the present application. The engine induction system includes a signal receiving module 1 , a timing module 2 and a signal output module 3 . In this embodiment and some other embodiments, the engine induction system is a part of the engine control unit. In other embodiments, the engine induction system may also be a separate system independent of the engine control unit. The engine control unit includes a readable and writable memory for writing commands or reading commands by other functional modules. The above-mentioned modules in this application can be completed using electronic devices, and can also be completed using software functions. The above-mentioned readable and writable memory has an acceleration induction command for the timing module 2 in the engine induction system to run at an acceleration speed, and the signal receiving module 1 can receive the above-mentioned acceleration induction command, and the timing module uses the acceleration speed to count to reach a preset timing result. , the signal output module 3 outputs the induction result. The engine control unit imposes certain restrictions on the operation of the vehicle according to the above-mentioned induction results, such restrictions include, but are not limited to, reducing the running speed of the vehicle, reducing the power of the vehicle, and providing uninterrupted warning information.

Please refer to FIG. 2 , which is a flowchart of an embodiment of the control method of the engine induction system of the present application. The typical usage scenario of the control method of the engine induction system of the present application is to test the effectiveness of the induction system, that is, when a specific scene occurs in the vehicle, generally after the engine control unit receives a fault report, the timing module in the induction system is used for timing, Test whether the induction result can be output normally after timing to the predetermined timing result. In step 001, the engine control unit receives the connection request of the diagnostic instrument. In step 002, the engine control unit verifies whether the diagnostic instrument is a valid diagnostic instrument. If the verification is invalid, it refuses to enter step 003. If the verification is If valid, go to step 003. In step 003, the engine control unit receives an instruction from the verifier, which in this embodiment is a specific coefficient. After receiving the specific coefficient, in step 004, the specific coefficient is stored in the memory of the engine control unit. The specific coefficient is a specific coefficient greater than 1 and less than 601, such as 100, 200, 300 and so on. In addition, in some embodiments including this embodiment, verification is included for whether the specific coefficient is greater than 1 and less than 601. If the specific coefficient does not meet the requirements, the engine control unit does not receive the instruction or does not store it. Next, in step 005, when the engine control unit sends a signal failure report, the signal receiving module 1 receives the failure report, and if the failure belongs to a specific failure of the startup induction system, it sends an acceleration induction command to the induction system. In step 006 , the engine induction system enters the acceleration induction mode. In the acceleration induction mode, the timing module 2 starts timing with the natural timing speed multiplied by the acceleration speed of the specific coefficient. Because the specific coefficient is greater than 1 and less than 601, the acceleration speed is greater than the natural time speed. . When the timing module of the induction system reaches the preset timing result, in this embodiment, the timing is set to 100 hours. If the specific coefficient is set to 100, the actual natural time is 1 hour to reach the preset timing result. At this time, the induction system outputs an induction result, and the induction result includes, but is not limited to, reducing the running speed of the engine, reducing the torque of the engine, providing uninterrupted warning information, and the like. Of course, the induction result issued by the induction system does not change the running state of the engine, which is an induction result.

In other embodiments, the control method of the induction system of the present application can be expressed in other forms, for example, the specific coefficient can be changed to a specific function, and the timer runs according to the specific function with natural time as a parameter. In addition, the specific coefficient or specific function can be stored in the memory of the engine control unit, and the memory is a read-only memory or a read-write memory. The specific coefficient or specific function can also be set in the induction system. After receiving the acceleration induction command from the engine control unit, the timer of the induction system enters the acceleration induction mode, and the timer starts to count at the acceleration speed.

The source of the acceleration induction command can be in different forms. For example, after the induction system receives the fault report, if it is judged to be a specific fault, it will generate the acceleration induction command by itself; or the acceleration induction command comes directly from the diagnostic instrument.

In addition, the inducing system further includes a time counting module, the time counting module counts the times every time the power is turned on and off after the engine control unit of the vehicle receives the specific coefficient or the specific function, and the time counting module counts the times when accumulatively After the predetermined number of times is reached, the timing module of the induction system can only be clocked at the natural timing speed. In this embodiment, the predetermined number of times is directly set in the induction system, and is set to 15 times. Of course, in other possible embodiments, the predetermined number of times can also be set by an external device, such as a diagnostic instrument of the induction system. The method of counting times can also be adjusted to count once every time the induction module runs at an accelerated speed. The setting of the counting module is to prevent the control method of the induction module from being used infinitely, and the counting result is stored in the read-write memory of the engine control unit.

The control method of the engine induction system of the present application can be implemented using software, so the present application also relates to a computer instruction sequence, which can be run on the engine induction system described in the present application and the control method of the engine induction system described above. .

Of course, the present application may also have other implementations, as long as the results do not violate the creative concept of the present application, they all belong to the protection scope of the present application.
