Description

Technical Field

[0001] This invention relates to the field of vehicle design technology, and in particular to a vehicle boost control method, electronic device, and readable storage medium. Background Technology

[0002] To meet increasingly stringent regulations on engine fuel consumption and emissions, engines are gradually becoming smaller and more integrated, and turbochargers are being widely used in this process. With the support of turbocharging technology, smaller displacement and smaller engines can achieve performance levels previously only attainable by larger displacement naturally aspirated engines, significantly improving power output per liter and greatly contributing to energy conservation and emission reduction.

[0003] Currently, the most commonly used technology is the exhaust gas turbocharger. Its working principle involves the turbine rotating at high speed under the drive of exhaust gas, which in turn drives a coaxial impeller, forcing more fresh gas into the cylinders to improve engine performance and provide users with a better acceleration driving experience. However, the opening control of the exhaust gas bypass valve in an exhaust gas turbocharger relies on the pressure difference formed by a three-way valve. By changing the pressure in the three channels of the three-way valve, positive and negative pressure control of the control chamber is achieved. The pressure difference pulls the diaphragm, which in turn moves the push rod, thereby controlling the opening of the exhaust gas bypass valve. This technology is limited by the pressure difference formed by the three-way valve, resulting in poor dynamic response of the exhaust gas bypass valve. To solve this dynamic response problem, EWG (Electronic Waste Gate) electronic exhaust gas bypass valve control technology was developed. Using this technology, the time for the exhaust gas bypass valve to go from fully open to fully closed is significantly shortened to the order of 200ms, enabling rapid dynamic response of the valve and providing better power. However, turbochargers driven by exhaust gas energy have a significant problem: turbo lag, especially at low speeds. Because the exhaust gas energy is relatively small, its ability to drive the turbine is limited, resulting in limited low-speed torque gains. In existing technology, the EWG electronic exhaust bypass valve is fully open in the non-boosting region and closes once the turbocharged region begins. This limits the utilization of exhaust gas energy only to the boosting region, leading to significant waste of exhaust gas energy in the non-boosting regions.

[0004] Therefore, how to provide a new vehicle boost control method to overcome the above-mentioned defects in the prior art has become one of the technical problems that urgently need to be solved by those skilled in the art. Summary of the Invention

[0005] The purpose of this invention is to provide a vehicle boost control method, electronic device, and readable storage medium to solve the problems in the prior art where the exhaust bypass valve is fully open in the non-boost region, resulting in low exhaust gas utilization and slow boost dynamic response.

[0006] To achieve the above objectives, the present invention provides a vehicle boost control method for controlling the valve opening of an exhaust gas bypass valve within the vehicle during vehicle operation. The control method includes:

[0007] The vehicle's driving conditions are obtained, and the pressure range of the exhaust bypass valve is determined.

[0008] When the exhaust bypass valve is in the first pressure zone, it is determined whether the vehicle is in the first acceleration state;

[0009] When the vehicle is in the first acceleration state, the exhaust gas bypass valve adjusts the valve opening according to the vehicle driving conditions and the first preset valve opening table.

[0010] The first preset valve opening table is configured as follows: various vehicle driving conditions and the corresponding first valve opening value of the exhaust gas bypass valve; wherein, 0 ≤ first valve opening value ≤ first preset threshold.

[0011] Optionally, the first acceleration state includes: when the accelerator pedal opening is greater than a first preset accelerator pedal opening within a first preset time period, and / or when the accelerator pedal increase gradient is greater than the first preset accelerator pedal increase gradient within the first preset time period.

[0012] Optionally, when the exhaust bypass valve is in the first pressure region and the vehicle is in the first acceleration state, the vehicle boost control method further includes: adjusting the throttle body, ignition angle and / or VVT;

[0014] The ignition angle is adjusted according to the vehicle driving conditions and the preset ignition angle table; the preset ignition angle table is configured to include: multiple vehicle driving conditions and corresponding ignition angle values.

[0015] The VVT ​​opening is adjusted according to the vehicle driving conditions and the VVT ​​preset opening table; the VVT ​​preset opening table is configured with: various vehicle driving conditions and corresponding VVT opening values.

[0016] Optionally, it also includes using a drive motor to control the first valve opening value of the waste gas bypass valve to remain at 0 when the first valve opening value of the waste gas bypass valve is 0.

[0017] Optionally, when the first valve opening value of the exhaust bypass valve controlled by the drive motor is kept at 0, the vehicle boost control method further includes:

[0018] If the output duty cycle of the drive motor within a preset cycle is greater than a preset limit duty cycle, and / or the closing time of the exhaust bypass valve is greater than a preset limit time, then the opening degree of the exhaust bypass valve is adjusted according to the vehicle driving conditions and a second preset valve opening table. The second preset valve opening table is configured with: various vehicle driving conditions and corresponding second valve opening values ​​for the exhaust bypass valve; wherein, the second preset threshold ≤ the second valve opening value ≤ 100%, and the second preset threshold > the first preset threshold.

[0019] If the output duty cycle of the drive motor within a preset cycle is less than a preset limit duty cycle, and the closing time of the exhaust bypass valve is less than a preset limit time, then the opening degree of the exhaust bypass valve is adjusted according to the vehicle driving conditions and the first preset valve opening degree table.

[0020] Optionally, the exhaust bypass valve may adjust its valve opening according to the vehicle's driving conditions and a third preset valve opening table when the exhaust bypass valve is in the first pressure zone and the vehicle is not in the first acceleration state, or when the exhaust bypass valve is in the second pressure zone.

[0021] Wherein, the pressure in the first pressure region is less than the pressure in the second pressure region;

[0022] The third preset valve opening table is configured to: various vehicle driving conditions and the corresponding third valve opening values ​​of the exhaust bypass valve.

[0023] Optionally, when the exhaust gas bypass valve is in the second pressure zone, and the exhaust gas bypass valve adjusts its valve opening according to the vehicle driving conditions and the third preset valve opening table, the vehicle boost control method further includes:

[0024] Determine whether the vehicle is in a second acceleration state;

[0025] If so, obtain the first valve opening of the exhaust bypass valve corresponding to the current vehicle driving condition according to the first preset valve opening table, and obtain the third valve opening of the exhaust bypass valve corresponding to the current vehicle driving condition according to the third preset valve opening table. Compare the first valve opening and the third valve opening, and take the valve opening with the smaller valve opening as the valve opening of the exhaust bypass valve.

[0026] If not, the exhaust bypass valve adjusts its opening according to the current vehicle driving conditions and the third preset valve opening table.

[0027] Optionally, the second acceleration state includes: when the accelerator pedal opening is greater than the second preset accelerator pedal opening within a second preset time period, and / or when the accelerator pedal increase gradient is greater than the second preset accelerator pedal increase gradient within the second preset time period;

[0028] Wherein, the second preset accelerator pedal opening is greater than the first preset accelerator pedal opening, and the second preset accelerator pedal increase gradient is greater than the first preset accelerator pedal increase gradient;

[0029] Alternatively, the second preset accelerator pedal opening is less than the first preset accelerator pedal opening, and the increase gradient of the second preset accelerator pedal is less than the increase gradient of the first preset accelerator pedal.

[0030] To achieve the above objectives, the present invention provides an electronic device, including a processor and a memory, wherein the memory stores a computer program, and when the computer program is executed by the processor, it implements the vehicle boost control method described above.

[0031] To achieve the above objectives, the present invention also provides a readable storage medium storing a computer program, which, when executed by a processor, implements the vehicle boost control method described in any of the preceding claims.

[0032] Compared with the prior art, the vehicle boost control method, electronic device, and readable storage medium provided by the present invention have the following advantages:

[0033] This invention provides a vehicle boost control method for controlling the valve opening of an exhaust gas bypass valve during vehicle operation. The control method first acquires the vehicle's driving conditions and determines the pressure range of the exhaust gas bypass valve. When the exhaust gas bypass valve is in a first pressure range, it determines whether the vehicle is in a first acceleration state. When the vehicle is in the first acceleration state, the exhaust gas bypass valve adjusts its valve opening according to the vehicle's driving conditions and a first preset valve opening table. The first preset valve opening table is configured with multiple vehicle driving conditions and corresponding first valve opening values ​​of the exhaust gas bypass valve, wherein 0 ≤ first valve opening value ≤ first preset threshold. Therefore, the vehicle boost control method provided by the present invention can set the first valve opening value corresponding to various vehicle driving conditions on the first preset valve opening table to a smaller value and / or fully closed. This allows the waste gas bypass valve to have a smaller opening or remain completely closed in the first pressure region (e.g., non-boost region) when the waste gas bypass valve is in the first pressure region and in the first acceleration state. This allows the waste gas bypass valve to reserve a certain amount of waste gas energy in advance for the boost device, so that the turbine speed is kept at a relatively high level, thereby further accelerating the boost dynamic response speed.

[0034] Since the electronic device and readable storage medium provided by this invention belong to the same inventive concept as the vehicle boost control method provided by this invention, they have at least the same technical effects, and will not be described in detail here.

[0038] The specific embodiments of the present invention will now be described in more detail with reference to the accompanying drawings. The advantages and features of the present invention will become clearer from the following description. It should be noted that the drawings are all in a very simplified form and use non-precise proportions, used only to facilitate and clarify the illustration of the embodiments of the present invention. It should be understood that the accompanying drawings do not necessarily show the specific structure of the present invention to scale, and the illustrative features used to illustrate certain principles of the present invention in the accompanying drawings are also drawn in a slightly simplified manner.

Furthermore, in the embodiments described below, the same reference numerals are sometimes used across different drawings to denote the same parts or parts having the same function, omitting repeated descriptions. In this specification, similar reference numerals and letters are used to denote similar items; therefore, once an item is defined in one drawing, it does not need to be further discussed in subsequent drawings.

[0039] Example 1

[0040] This embodiment provides a vehicle boost control method for controlling the valve opening of the exhaust gas bypass valve during vehicle operation. For details, please refer to the appendix. Figure 1 , Figure 1 A flowchart illustrating the vehicle boost control method provided in this embodiment is given. From Figure 1 As can be seen, the vehicle boost control method provided in this embodiment includes:

[0041] S100: Obtain vehicle driving conditions and determine the pressure range of the exhaust bypass valve.

[0042] S200: When the exhaust bypass valve is in the first pressure zone, determine whether the vehicle is in the first acceleration state;

[0043] S300: When the vehicle is in the first acceleration state, the exhaust gas bypass valve adjusts the valve opening according to the vehicle driving conditions and the first preset valve opening table.

[0044] The first preset valve opening table is configured to include: various vehicle driving conditions and the corresponding first valve opening values ​​of the exhaust bypass valve; wherein, 0 ≤ first valve opening value ≤ first preset threshold.

[0045] With this configuration, the vehicle boost control method provided by the present invention can set the first valve opening values ​​corresponding to various vehicle driving conditions on the first preset valve opening table to a smaller value and / or fully closed. This allows the waste gas bypass valve to have a smaller opening or remain completely closed in the first pressure region (e.g., non-boost region) when the waste gas bypass valve is in the first pressure region and in the first acceleration state. This allows the waste gas bypass valve to reserve a certain amount of waste gas energy in advance for the boost device, so that the turbine speed is kept at a relatively high level, thereby further accelerating the boost dynamic response speed.

[0046] It should be noted that the vehicle operating conditions include engine speed and engine load.

[0047] Preferably, the first acceleration state includes: triggering when the accelerator pedal opening is greater than a first preset accelerator pedal opening within a first preset time period, and / or when the accelerator pedal increase gradient is greater than a first preset accelerator pedal increase gradient within the first preset time period. This ensures that during vehicle operation, when an acceleration request is received, the exhaust gas bypass valve can adjust its valve opening according to the first preset valve opening table, pre-storing exhaust gas energy for the turbocharger and maintaining the turbine speed at a relatively high level to accelerate the turbocharger's dynamic response speed, thereby quickly achieving the vehicle's acceleration purpose. It should be noted that accelerator pedal opening and accelerator pedal increase gradient are not the only conditions for determining whether the vehicle is in the first acceleration state. This invention provides conditions including, but not limited to, using torque, load demand, and / or the magnitude of the load increase gradient as conditions for determining whether the vehicle is in the first acceleration state.

[0048] Please continue reading the appendix. Figure 2 , Figure 2 A flowchart illustrating the adjustment of throttle opening, ignition angle, and / or VVT opening in conjunction with the wastegate valve, as provided in this embodiment, is illustrated. From... Figure 2 It can be seen that when the exhaust bypass valve is in the first pressure region and the vehicle is in the first acceleration state, the vehicle boost control method further includes: adjusting the throttle, ignition angle and / or VVT;

[0049] The throttle opening is adjusted according to the vehicle driving conditions and the preset throttle opening table; the preset throttle opening table is configured to include various vehicle driving conditions and corresponding throttle opening values.

[0050] The ignition angle is adjusted according to the vehicle driving conditions and the preset ignition angle table; the preset ignition angle table is configured to include: multiple vehicle driving conditions and corresponding ignition angle values.

[0051] The VVT ​​opening is adjusted according to the vehicle driving conditions and the VVT ​​preset opening table; the VVT ​​preset opening table is configured with: various vehicle driving conditions and corresponding VVT opening values.

[0052] Therefore, by simultaneously adjusting the throttle opening, ignition angle, and / or VVT opening, the boost dynamic response speed can be further accelerated. Furthermore, those skilled in the art will understand that for engines with dual VVT configurations, the valve opening adjustment of dual VVT can be addressed by setting preset intake VVT ​​and exhaust VVT opening gauges.

[0053] Preferably, the vehicle boost control method provided in this embodiment further includes: when the first valve opening value of the exhaust gas bypass valve is 0, using a drive motor to control the first valve opening value of the exhaust gas bypass valve to remain at 0. Thus, the drive motor supplies power to the exhaust gas bypass valve, enabling the exhaust gas bypass valve to remain completely closed in the first pressure region, pre-storing exhaust gas energy for the boost device, thereby further improving the boost dynamic response speed.

[0054] In one preferred embodiment, when the first valve opening value of the exhaust bypass valve controlled by the drive motor is kept at 0, the vehicle boost control method further includes:

[0055] If the output duty cycle of the drive motor within a preset cycle is greater than a preset limit duty cycle, and / or the closing time of the exhaust bypass valve is greater than a preset limit time, then the opening degree of the exhaust bypass valve is adjusted according to the vehicle driving conditions and a second preset valve opening table. The second preset valve opening table is configured with: various vehicle driving conditions and corresponding second valve opening values ​​for the exhaust bypass valve; wherein, the second preset threshold ≤ the second valve opening value ≤ 100%, and the second preset threshold > the first preset threshold.

[0056] If the output duty cycle of the drive motor within a preset cycle is less than a preset limit duty cycle, and the closing time of the exhaust bypass valve is less than a preset limit time, then the opening degree of the exhaust bypass valve is adjusted according to the vehicle driving conditions and the first preset valve opening degree table.

[0057] Therefore, this embodiment can set the second valve opening value corresponding to various vehicle driving conditions on the second preset valve opening table to a larger and / or fully open state, so that when the drive motor supplies power to the exhaust gas bypass valve for a long time, after the exhaust gas bypass valve adjusts its valve opening according to the second preset valve opening table, the exhaust gas bypass valve can maintain a larger opening or fully open state in the first pressure region, thereby reducing the load on the drive motor and achieving overload protection for the drive motor.

[0058] Preferably, the vehicle boost control method provided in this embodiment further includes adjusting the valve opening according to the vehicle driving conditions and a third preset valve opening table when the exhaust gas bypass valve is in a first pressure region and not in the first acceleration state, or when the exhaust gas bypass valve is in a second pressure region; wherein the pressure in the first pressure region is less than the pressure in the second pressure region; the third preset valve opening table is configured to include various vehicle driving conditions and corresponding third valve opening values ​​of the exhaust gas bypass valve. Therefore, when the driver does not request acceleration, i.e., when no additional exhaust gas energy is required, the exhaust gas bypass valve can adjust its opening according to the third preset valve opening table to maintain a suitable valve opening.

[0059] Please continue reading the appendix. Figure 3 , Figure 3 A schematic flowchart illustrating the valve opening switching of the waste gas bypass valve in the second pressure zone provided in this embodiment is given. From Figure 3 It can be seen that when the exhaust gas bypass valve is in the second pressure zone, and the exhaust gas bypass valve adjusts its valve opening according to the vehicle driving conditions and the third preset valve opening table, the vehicle boost control method further includes:

[0060] Determine whether the vehicle is in a second acceleration state; in one preferred embodiment, the second acceleration state includes: triggering when the accelerator pedal opening is greater than a second preset accelerator pedal opening within a second preset time period, and / or when the accelerator pedal increase gradient is greater than a second preset accelerator pedal increase gradient within the second preset time period; wherein, the second preset accelerator pedal opening is greater than the first preset accelerator pedal opening, and the second preset accelerator pedal increase gradient is greater than the first preset accelerator pedal increase gradient; or the second preset accelerator pedal opening is less than the first preset accelerator pedal opening, and the second preset accelerator pedal increase gradient is less than the first preset accelerator pedal increase gradient.

[0061] If so, obtain the first valve opening of the exhaust bypass valve corresponding to the current vehicle driving condition according to the first preset valve opening table, and obtain the second valve opening of the exhaust bypass valve corresponding to the current vehicle driving condition according to the third preset valve opening table. Compare the first valve opening and the second valve opening, and take the valve opening with the smaller valve opening as the valve opening of the exhaust bypass valve.

[0062] If not, the exhaust bypass valve adjusts its opening according to the current vehicle driving conditions and the third preset valve opening table.

[0063] Therefore, when the driver still requests acceleration, a smaller valve opening is used as the valve opening of the exhaust bypass valve by comparison, thereby storing more exhaust gas energy for the booster equipment to further improve the booster dynamic response speed.

[0064] To better illustrate the vehicle boost control method provided by this invention, an experimental comparison was conducted between the vehicle boost control method provided in the above embodiments and a normal boost control strategy. The results showed that when the same 2.0TGDI engine reached 2000 rpm, the normal boost control strategy required 2.5 seconds to reach maximum boost pressure, while the vehicle boost control method provided by this invention only required 2.28 seconds, representing an improvement of approximately 10% in boost dynamic response time. Furthermore, in the 1500 rpm constant speed transient response test of the 2.0TGDI engine, the response time using the vehicle boost control method provided by this invention was close to that at 2000 rpm, also showing an improvement of approximately 10%. Therefore, this further demonstrates that the vehicle boost control method provided by this invention can accelerate the boost dynamic response rate, thereby enhancing the vehicle acceleration experience.
