Description

Technical Field

[0001] The present application relates to the field of electromechanical technology, and in particular to a calibration-based supercharger surge elimination method and system. Background Art

[0002] Superchargers pre-compress the air or combustible mixture entering the engine cylinder to increase its density, thereby improving the engine's power, economy and emission performance. Due to these advantages, superchargers are increasingly used in engines. However, under certain complex operating conditions, superchargers may experience surge problems, causing engine noise, affecting passenger comfort, and in severe cases, reducing engine performance.

[0003] Current supercharger surge control technology mainly relies on adding control devices such as a pressure relief valve, an intake throttle valve, an exhaust throttle valve, a throttle valve, and an EGR (Exhaust Gas Re-circulation) valve to solve the supercharger surge problem. For example, the engine control unit ECU (Electronic Control Unit) outputs different anti-surge control signals to the intake throttle valve, the EGR valve, and the exhaust throttle valve according to different engine combustion modes to control supercharger surge; or obtains the minimum flow value of the gas entering the throttle valve to avoid compressor surge, compares the minimum flow value with the throttle flow value expected by the driving intention, and when the throttle flow value expected by the driving intention is less than the minimum flow value, delays closing the throttle valve according to the minimum flow value.

[0004] However, the method of solving the supercharger surge problem by adding an additional control device has the disadvantages of complex structure and high cost. Summary of the invention

[0005] The present application provides a calibration-based supercharger surge elimination method and system, which can solve the technical problems of complex structure and high cost in the current supercharger surge control technology.

[0006] To achieve the above objectives, in a first aspect, the present application provides a calibration-based supercharger surge elimination method, the method comprising:

[0007] Shift gears in sequence according to the gear sequence of the vehicle. In each gear after shifting, increase the engine speed to the preset speed at full throttle and release the accelerator sharply.

[0008] If surge occurs when you release the throttle suddenly:

[0009] According to the preset speed-torque filter coefficient mapping table, the first torque filter coefficient corresponding to the preset speed when surge occurs is found, and the first torque filter coefficient is gradually reduced according to the preset reduction benchmark. After each reduction, the engine speed is fully accelerated to the preset speed at which the surge occurs and the throttle is suddenly released until the surge is eliminated.

[0010] If surge occurs during a gear shift:

[0011] According to a preset neutral speed-torque filter coefficient mapping table, a second torque filter coefficient corresponding to the neutral speed when surge occurs is found, and the second torque filter coefficient is gradually reduced according to a preset reduction benchmark. After each reduction, the shifting process when surge occurs is repeated until the surge is eliminated.

[0012] Furthermore, in one embodiment, when the first torque filter coefficient is reduced to a preset minimum threshold value of the torque filter coefficient, if surge still exists, the corresponding third torque filter coefficient is found from a preset gear-speed-torque filter coefficient mapping table according to the gear and preset speed when surge occurs.

[0013] The third torque filter coefficient is gradually reduced according to a preset reduction reference. After each reduction, the engine speed is accelerated to a preset speed at which the surge occurs and the throttle is suddenly released until the surge is eliminated.

[0014] Furthermore, in one embodiment, if the speed-torque filter coefficient mapping table does not include a preset speed when surge occurs, a speed that is closest to the preset speed and less than the preset speed is found in the mapping table, and the torque filter coefficient corresponding to the speed is used as the first torque filter coefficient.

[0015] If the gear-speed-torque filter coefficient mapping table does not include the preset speed when surge occurs, the third torque filter coefficient is found in the same way.

[0016] Furthermore, in one embodiment, the speeds in the speed-torque filter coefficient mapping table, the gear-speed-torque filter coefficient mapping table and the neutral speed-torque filter coefficient mapping table are divided into a low speed area and a high speed area, and the speed calibration interval in the low speed area is smaller than the speed calibration interval in the high speed area.

[0017] Furthermore, in one embodiment, the torque filter coefficients in the speed-torque filter coefficient mapping table, the gear-speed-torque filter coefficient mapping table and the neutral speed-torque filter coefficient mapping table have different values ​​corresponding to different altitudes.

[0018] Furthermore, in one embodiment, the gear sequence of the vehicle is to increase gears step by step from low to high, or to decrease gears step by step from high to low.

[0019] Furthermore, in one embodiment, after surging is eliminated, the torque filter coefficient reduced when surging is eliminated is gradually increased according to a preset callback reference, and is determined to be at a maximum value at which surging does not occur.

[0020] Furthermore, in one embodiment, the callback reference is smaller than the reduction reference, and the maximum value without surge is smaller than the value of the torque filter coefficient after the previous reduction that eliminates the surge.

[0021] In a second aspect, based on the calibration-based supercharger surge elimination method, the present application provides a calibration-based supercharger surge elimination system, the supercharger surge elimination system comprising:

[0022] The gear shifting module is used to shift gears in sequence according to the gear sequence of the vehicle.

[0023] The acceleration module is used to accelerate the engine speed to each preset speed at full throttle in sequence after each gear change, and then release the throttle suddenly.

[0024] The elimination module is used to eliminate surge.

[0025] If surge occurs when the accelerator is suddenly released, the elimination module is used to find the first torque filter coefficient corresponding to the preset speed when the surge occurs according to the preset speed-torque filter coefficient mapping table, and gradually reduce the first torque filter coefficient according to a preset reduction benchmark. After each reduction, the speed-up module increases the engine speed at full throttle to the preset speed at which the surge occurs and suddenly releases the accelerator until the surge is eliminated.

[0026] If surge occurs during gear shifting: the elimination module is used to find the second torque filter coefficient corresponding to the neutral speed when surge occurs according to a preset neutral speed-torque filter coefficient mapping table, and gradually reduce the second torque filter coefficient according to a preset reduction benchmark. After each reduction, the gear shifting process when surge occurs is repeated until the surge is eliminated.

[0027] Furthermore, in one embodiment, the supercharger surge elimination system further includes:

[0028] A callback module is used to gradually increase the torque filter coefficient reduced to when the surge is eliminated with a preset callback benchmark after the surge is eliminated, and determine it at a maximum value without surge, the callback benchmark is smaller than the reduction benchmark, and the maximum value without surge is smaller than the value of the torque filter coefficient after the previous reduction when the surge is eliminated.

[0029] The beneficial effects brought by the technical solution provided in the embodiments of the present application include:

[0030] The present application shifts gears in sequence according to the gear sequence of the vehicle. In each gear after the gear shift, the engine speed is accelerated to each preset speed at full throttle in sequence, and the throttle is suddenly released. For the situation that surge occurs when the throttle is suddenly released and during the gear shift, a corresponding relationship mapping table of the preset speed, gear and torque filter coefficient is used to reduce the torque attenuation rate by reducing the torque filter coefficient, thereby eliminating surge. There is no need to add additional control devices, which effectively reduces the complexity and cost of the supercharger surge control technology and improves the driving experience.

[0032] Figure 2 It is a block diagram of a supercharger surge elimination system based on calibration according to an embodiment of the present application. DETAILED DESCRIPTION

[0033] In order to enable those skilled in the art to better understand the solution of the present application, the technical solution in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application.

[0034] In order to make the objectives, technical solutions and advantages of the present application more clear, the implementation methods of the present application will be further described in detail below with reference to the accompanying drawings.

[0035] First of all, it should be noted that when the throttle is released suddenly during driving, especially under the condition of small flow and large pressure ratio, the intake volume will decrease sharply, and the turbine shaft of the turbocharger cannot respond immediately due to inertia, so the turbocharger speed and the boost pressure ratio remain unchanged for a certain period of time, causing the operating point to reach the turbocharger surge line area. In the process of suddenly dropping from full throttle to zero throttle, the airflow angle is smaller than the compressor blade angle, resulting in the actual torque value being higher than the actual torque limit. At this time, the torque drop rate will exceed the rate of decrease of the actual torque limit, thereby increasing the risk of surge.

[0036] In addition, during vehicle gear shifting, the turbocharger turbine speed will change rapidly, causing the engine power response to deteriorate and surging to occur.

[0037] In a first aspect, an embodiment of the present application provides a calibration-based supercharger surge elimination method.

[0038] In one embodiment, see Figure 1 As shown, the above-mentioned supercharger surge elimination method includes:

[0039] S1. Shift gears in sequence according to the gear sequence of the vehicle. At each gear after shifting, increase the engine speed to the preset speed at full throttle and release the throttle quickly.

[0040] S2. Determine the specific circumstances under which the surge occurs. If the surge occurs when the accelerator is suddenly released, enter S3; if the surge occurs during a gear shift, enter S4.

[0041] S3. According to a preset speed-torque filter coefficient mapping table, find the first torque filter coefficient corresponding to the preset speed when surge occurs, gradually reduce the first torque filter coefficient according to a preset reduction benchmark, and after each reduction, increase the engine speed to the preset speed at which the surge occurs at full throttle and release the throttle sharply until the surge is eliminated.

[0042] S4. According to a preset neutral speed-torque filter coefficient mapping table, find the second torque filter coefficient corresponding to the neutral speed when surge occurs, gradually reduce the second torque filter coefficient according to a preset reduction benchmark, and after each reduction, repeat the shifting process when surge occurs until surge is eliminated.

[0043] This embodiment shifts gears in sequence according to the gear sequence of the vehicle. In each gear after the gear shift, the engine speed is accelerated to each preset speed at full throttle in sequence, and the throttle is suddenly released. A corresponding relationship mapping table of preset speed, gear and torque filter coefficient is preset. If the vehicle surges when the throttle is suddenly released or during the gear shift, the torque filter coefficient corresponding to the preset speed when the surge occurs is found in the corresponding relationship mapping table of preset speed, gear and torque filter coefficient, and the torque filter coefficient is gradually reduced according to the preset reduction benchmark until the surge is eliminated. This embodiment does not need to add additional control devices, effectively simplifies the supercharger surge control technology, reduces technical costs, and improves the driving experience.

[0044] Further, in one embodiment, in the above step S3, if surge occurs when the accelerator is suddenly released:

[0045] S311, determine whether the above-mentioned preset speed-torque filter coefficient mapping table contains the preset speed when surge occurs, if so, go to step S312, if not, go to step S313.

[0046] S312, finding the first torque filter coefficient corresponding to the preset speed when surge occurs in the preset speed-torque filter coefficient mapping table, gradually reducing the first torque filter coefficient according to a preset reduction reference, and entering S314.

[0047] S313. In a preset speed-torque filter coefficient mapping table, find a speed that is closest to the preset speed and less than the preset speed, and gradually reduce the first torque filter coefficient corresponding to the speed according to a preset reduction reference.

[0048] S314, after reducing the first torque filter coefficient each time, the engine speed is accelerated to a preset speed at which the surge occurs and the accelerator is quickly released until the surge is eliminated, and the process proceeds to step S315.

[0049] S315, gradually increase the first torque filter coefficient reduced to when eliminating surge with a preset callback reference, and determine it at the maximum value without surge. Wherein, the callback reference is less than the reduction reference, and the maximum value of the first torque filter coefficient without surge is less than the value of the first torque filter coefficient after the previous reduction to eliminate surge. Specifically, if the value of the first torque filter coefficient after the previous reduction to eliminate surge is M, and the maximum value of the first torque filter coefficient without surge after callback is N, then N <M。

[0050] In this embodiment, according to the preset speed-torque filter coefficient mapping table, the surging that occurs when the accelerator is suddenly released is eliminated by gradually reducing the torque filter coefficient and testing it. By calling back the torque filter coefficient, it is avoided to a certain extent that the torque filter coefficient is too small, resulting in the driver's lack of obvious deceleration after releasing the accelerator, causing the driver to frequently step on the brakes, thereby improving the driving experience and enhancing driving comfort.

[0051] Further, in one embodiment, when the first torque filter coefficient in the above step S3 is reduced to a preset minimum threshold value of the torque filter coefficient, if there is still surging in the vehicle, the step of eliminating the surging includes:

[0052] S321. Determine whether the preset gear-speed-torque filter coefficient mapping table contains the preset speed when surge occurs. If so, proceed to step S322; if not, proceed to step S323.

[0053] S322. Find the third torque filter coefficient corresponding to the preset speed when surge occurs in the preset gear-speed-torque filter coefficient mapping table, gradually reduce the third torque filter coefficient according to the preset reduction reference, and enter S324.

[0054] S323. In a preset gear-speed-torque filter coefficient mapping table, find a speed that is closest to the preset speed and less than the preset speed, and gradually reduce the third torque filter coefficient corresponding to the speed according to a preset reduction reference.

[0055] S324, after each reduction of the third torque filter coefficient, the engine speed is accelerated to a preset speed at which the surge occurs and the accelerator is quickly released until the surge is eliminated, and the process proceeds to step S325.

[0056] S325, gradually increase the third torque filter coefficient that is reduced when eliminating surge with a preset callback reference, and determine it to be the maximum value without surge. Wherein, the callback reference is less than the reduction reference, and the maximum value of the third torque filter coefficient without surge is less than the value of the third torque filter coefficient after the previous reduction to eliminate surge. Specifically, if the value of the third torque filter coefficient after the previous reduction to eliminate surge is X, and the maximum value of the third torque filter coefficient without surge after callback is Y, then Y <X。

[0057] Further, in one embodiment, the speeds in the speed-torque filter coefficient mapping table, the gear-speed-torque filter coefficient mapping table, and the neutral speed-torque filter coefficient mapping table are divided into a low speed region and a high speed region, and the speed calibration interval of the low speed region in each mapping table is smaller than the speed calibration interval of the high speed region. Specifically:

[0058] In each mapping table, a partition value is preset, and the speed in the vehicle's speed range that is less than the partition value is classified as a low speed area, and the speed in the vehicle's speed range that is greater than the partition value is classified as a high speed area, wherein the low speed area corresponds to a first speed interval, the high speed area corresponds to a second speed interval, and the first speed interval is smaller than the second speed interval.

[0059] In this embodiment, by dividing the speed area into low speed area and high speed area, the speed-torque filter coefficient mapping table, the gear-speed-torque filter coefficient mapping table, and the neutral speed-torque filter coefficient mapping table are calibrated at different speed intervals, thereby improving the accuracy of the correspondence between the speed and torque filter coefficient.

[0060] Furthermore, in one embodiment, the torque filter coefficients in the speed-torque filter coefficient mapping table, the gear-speed-torque filter coefficient mapping table and the neutral speed-torque filter coefficient mapping table have different values ​​corresponding to different altitudes.

[0061] In this embodiment, by setting different torque filter coefficients at different altitudes, the embodiment of the present application can be used to eliminate surging caused by shifting gears and accelerating the engine speed to full throttle and then suddenly releasing the throttle when the vehicle is traveling at different altitudes, thereby increasing the scope of application of the embodiment of the present application.

[0062] Furthermore, in one embodiment, the gear sequence of the vehicle is gradually increased from low to high, or gradually decreased from high to low. Specifically, the gear can be increased in the order of 0 gear-1 gear, 1 gear-2 gear, 2 gear-3 gear, 3 gear-4 gear, 4 gear-5 gear, 5 gear-6 gear, or decreased in the order of 6 gear-5 gear, 5 gear-4 gear, 4 gear-3 gear, 3 gear-2 gear, 2 gear-1 gear.

[0063] Furthermore, in one embodiment, in order to avoid missing the occurrence of surge, the above-mentioned gear shifting is performed multiple times, and in each gear after the gear shift, the engine speed is accelerated to each preset speed at full throttle in sequence, and the throttle is suddenly released.

[0064] In a second aspect, based on the calibration-based supercharger surge elimination method, an embodiment of a calibration-based supercharger surge elimination system is provided. Figure 2 As shown, the above system includes a shift module, a speed-up module and an elimination module, specifically:

[0065] The gear shifting module is used to shift gears in sequence according to the gear sequence of the vehicle.

[0066] The acceleration module is used to accelerate the engine speed to each preset speed at full throttle in sequence after each gear change, and then release the throttle suddenly.

[0067] The elimination module is used to eliminate surge.

[0068] If surge occurs when the accelerator is suddenly released, the elimination module is used to find the first torque filter coefficient corresponding to the preset speed when the surge occurs according to the preset speed-torque filter coefficient mapping table, and gradually reduce the first torque filter coefficient according to a preset reduction benchmark. After each reduction, the speed-up module increases the engine speed at full throttle to the preset speed at which the surge occurs and suddenly releases the accelerator until the surge is eliminated.

[0069] If surge occurs during gear shifting: the elimination module is used to find the second torque filter coefficient corresponding to the neutral speed when surge occurs according to a preset neutral speed-torque filter coefficient mapping table, and gradually reduce the second torque filter coefficient according to a preset reduction benchmark. After each reduction, the gear shifting process when surge occurs is repeated until the surge is eliminated.

[0070] Furthermore, in one embodiment, the supercharger surge elimination system further includes a callback module, which is used to gradually increase the torque filter coefficient reduced to when the surge is eliminated with a preset callback reference after the surge is eliminated, and determine it at the maximum value without surge, the callback reference is less than the reduction reference, and the maximum value without surge is less than the value of the torque filter coefficient after the previous reduction to eliminate the surge.

[0071] This application divides the surge occurrence scenarios into two scenarios: sudden release of the accelerator during vehicle driving and during gear shifting, which can correspond to two elimination modes respectively. According to the surge occurrence scenario, surge can be eliminated by selecting the corresponding elimination mode. Each elimination mode corresponds to a different mapping table of corresponding speeds, gears, and torque filter coefficients. By reducing the torque filter coefficient corresponding to the speed or gear when surge occurs, or according to the torque filter coefficient corresponding to the speed and gear when surge occurs, the torque attenuation rate is reduced to eliminate surge. For superchargers that are not equipped with throttles and EGR, this application can eliminate surge without adding additional control devices, effectively reducing the cost of surge elimination technology.
