Description

Technical Field

[0001] The present application relates to the field of vehicle technology, and in particular to a vehicle and a control method, device, electronic device, and storage medium thereof. Background Art

[0002] After the vehicle is parked, the internal oil pressure of the fuel pipeline will decrease as the parking time increases due to leakage of the pressure valve components inside the pipeline, which may cause the vehicle to fail to ignite successfully at one time when it is restarted. For this reason, the relevant technology proposes that when the vehicle receives the ignition command, the low-pressure oil pump is first controlled to run and build pressure for a few seconds to pre-build pressure on the oil pipeline. However, this technology requires the user to wait for a few seconds before starting the vehicle, and the driving experience is not good. In addition, if the user has no driving needs, the pre-pressure building process in the above technology will cause the low-pressure oil pump to operate ineffectively, resulting in unnecessary energy consumption. At the same time, the noise and vibration associated with the operation of the low-pressure oil pump will also bring a bad driving experience. Summary of the Invention

[0031] The following describes in detail embodiments of the present application. Examples of the embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are intended to be used to explain the present application, and should not be construed as limiting the present application.

[0032] As the number of vehicles increases, more and more families own two or more vehicles, and it is inevitable that they will not use their vehicles for a long time. In this case, due to leakage of the internal pressure valve of the fuel line, the internal oil pressure of the pipeline will decrease over time. When the engine is started again, it may not be able to ignite successfully in one go. Therefore, in order to ensure the first successful ignition after the vehicle has been parked for a long time, the relevant technology first controls the low-pressure oil pump to run for a few seconds when the vehicle receives the ignition command to pre-establish sufficient pressure in the low-pressure oil pipeline and fuel rail. The following explains the defects of this technology according to the engine ignition method:

[0033] Ignition method 1: Mechanical key start

[0034] First, insert the mechanical key and turn it to the "ON" position. The low-pressure fuel pump will run for a few seconds to build up oil pressure. Then, turn the mechanical key to the "START" position to start the engine. However, in daily vehicle use, you may encounter scenarios where you need to start the vehicle as soon as possible, such as when you have an emergency. In such scenarios, users do not want to wait these few seconds, so they will turn the mechanical key directly from "ON" to "START". At this time, the vehicle has not been driven for a long time, resulting in insufficient oil pressure in the fuel line. This may cause the engine to fail to start on the first ignition, resulting in a very poor driving experience.

[0035] Ignition method two: one-button start

[0036] When the vehicle is started with one button, it is unlocked and powered on, and the low-pressure fuel pump starts running for a few seconds to build up sufficient pressure. However, in some scenarios where the user does not need to drive, for example, after starting the vehicle with one button, the user simply wants to open the door to retrieve something or just want to take a nap in the seat, etc., the pre-built pressure will cause the low-pressure fuel pump to operate ineffectively, resulting in unnecessary energy consumption. At the same time, the accompanying noise and vibration will also bring a poor driving experience.

[0037] To this end, this application discloses a vehicle control method to achieve successful engine ignition on the first try and reduce ineffective operation of the low-pressure oil pump. Corresponding to this vehicle control method, this application also discloses a vehicle control device, a vehicle control system, a vehicle, a controller, and a computer-readable storage medium.

[0038] Figure 1 This is a flow chart of the vehicle control method of the embodiment of the present application. The method can be implemented by a controller or by Figure 2 The system architecture shown is implemented.

[0039] like Figure 1 As shown, the vehicle control method includes:

[0040] S11 , in response to a vehicle unlocking instruction, obtaining vehicle status information.

[0041] In this embodiment, the vehicle unlocking command can be triggered by the vehicle's remote control key (such as a Bluetooth key, a radio frequency key), a mechanical key, etc., and can be unlocked by the vehicle's door lock switch (such as a Figure 2 The door lock switch-driver, door lock switch-passenger, door lock switch-rear row, door lock switch-trunk) detection shown in the figure, for example, the user can issue a door unlock command through the door unlock button on the remote control key, or issue a vehicle unlock command through the radio frequency signal of the remote control key. For example, the user can issue a vehicle unlock command by opening the door with a mechanical key. If the door lock switch is unlocked according to the vehicle unlock command, the vehicle unlock command is transmitted to the controller that executes the method of the present application, or, after Figure 2 The vehicle body control unit is shown connected to the CAN (Controller Area Network) line so that the information processing module 22 can obtain and process it. It should be understood that the vehicle unlock command is a command different from the engine ignition command. The vehicle unlock command is used to unlock the doors, trunk door, etc., while the engine ignition command is used to start the vehicle engine.

[0042] Vehicle status information can be collected by a detection device (or sensing device) provided on the vehicle, wherein the detection device may include Figure 2One or more of the key detection module, driver's seat belt switch, multimedia system, driver's seat position sensor, driver's backrest angle sensor, driver's seat pressure sensor, driver posture confirmation module, ignition device (button / key), fuel pressure sensor, oil level sensor, and brake pedal sensor shown.

[0043] Exemplarily, the vehicle status information includes: the distance between the remote control key and the vehicle, the oil pressure in the vehicle's fuel line, the vehicle's main driver's door status, the vehicle's main driver's seat position, the vehicle's seat belt status, the vehicle's brake pedal opening, the vehicle's engine ignition command, and at least one of the main driver's seat occupant status, wherein the main driver's seat occupant status may include at least one of the main driver's seat occupant posture, the main driver's seat occupant age, the main driver's seat occupant identity information, and the main driver's seat occupant weight.

[0044] S12, controlling the pressure building of the vehicle's low-pressure oil pump according to the vehicle status information.

[0045] Specifically, vehicle status information can be used to determine driving demand, such as the presence or absence of driving demand, the degree of driving demand, and the level of driving demand. Pressure buildup control can then be implemented on the vehicle's low-pressure fuel pump based on the driving demand. For example, when driving demand is present, pressure buildup control can be implemented on the low-pressure fuel pump based on the driving demand (such as the degree of driving demand, the level of driving demand, etc.) to ensure timely control of the low-pressure fuel pump's pressure buildup. This allows for successful engine ignition upon subsequent receipt of an engine ignition command, reducing waiting time. When driving demand is absent, pressure buildup control on the low-pressure fuel pump can be disabled, thereby reducing ineffective operation of the low-pressure fuel pump.

[0046] In some embodiments of the present application, the vehicle status information includes the oil pressure in the vehicle's fuel line (which may be the oil pressure when the vehicle is unlocked). Controlling the pressure buildup of the vehicle's low-pressure fuel pump based on the vehicle status information includes: controlling the pressure buildup of the vehicle's low-pressure fuel pump based on the oil pressure.

[0047] Specifically, when the oil pressure is high (such as greater than the preset high-pressure threshold), the engine can be ignited successfully in one go. At this time, there is no need to pre-start the low-pressure oil pump to build up pressure, and the vehicle can be controlled in the conventional manner; when the oil pressure is low (such as less than or equal to the preset high-pressure threshold), the low-pressure oil pump needs to be pre-started to build up pressure. At this time, the low-pressure oil pump is controlled to start and build up pressure in the fuel pipeline, so that when the engine is started, the engine can be ignited successfully in one go, reducing the user's waiting time and improving the driving experience.

[0048] In some embodiments of the present application, the vehicle's low-pressure oil pump is pressure-built and controlled according to the vehicle status information, including: determining the driving demand according to the vehicle status information, and controlling the vehicle's low-pressure oil pump pressure-built according to the driving demand.

[0049] Specifically, when there is no driving demand, the low-pressure fuel pump can be disabled from building up pressure to reduce ineffective operation. When there is a driving demand, the low-pressure fuel pump can be activated to build up pressure in the fuel pipeline, ensuring a successful first-time engine ignition when starting the engine, reducing user waiting time and improving the driving experience.

[0050] Exemplarily, the vehicle status information includes the distance between the remote control key and the vehicle; determining the driving demand situation based on the vehicle status information includes: if the distance is greater than a target distance threshold, determining the driving demand situation as no driving demand; if the distance is less than or equal to the target distance threshold, determining the driving demand situation as having a driving demand

[0051] The target distance threshold is determined based on the oil pressure and a preset time margin. The preset time margin is a constant value that can be fixed or customized, calibrated based on experience, or based on the time it takes for the user to open the car door and ignite the engine. Specifically, the lower the oil pressure, the longer it takes to pre-start the low-pressure oil pump to build pressure. The pressure buildup time can be determined based on the oil pressure. To ensure that the pressure is built before the engine ignites, the pressure buildup time should be less than or equal to [(target distance threshold / pace) + preset time margin]. The result is that the target distance threshold ≥ (pressure buildup time - preset time margin) * pace. The pace can be pre-calibrated and is a fixed value.

[0052] Specifically, if the distance is greater than the target distance threshold, it indicates that the user with the remote key is far away from the vehicle. Even if the user intends to drive and the fuel pressure is low, there's still time to pre-prime the low-pressure fuel pump. Therefore, the current driving demand can be defined as no, eliminating the need to pre-prime the low-pressure fuel pump. The vehicle status information can then be used to determine the driving demand. Conversely, if the distance is less than or equal to the target distance threshold, it indicates that the user with the remote key is close to the vehicle and may intend to drive. Therefore, the current driving demand can be defined as present.

[0053] For example, when the distance between the vehicle's remote control key and the vehicle is greater than the target distance threshold, if a vehicle lock command is received, it means that the user has no intention of driving. At this time, the user can exit the vehicle control process of this application and re-enter the vehicle control process of this application when the vehicle unlock command is received again.

[0054] In some embodiments of the present application, the vehicle state also includes the oil pressure in the vehicle fuel line. Figure 3 As shown, the vehicle's low-pressure oil pump is controlled to build pressure according to the vehicle status information, including:

[0055] S121, determining driving demand conditions based on vehicle status information.

[0056] The driving demand situation includes whether there is a driving demand. For details, please refer to the above description of the method of "determining based on the distance between the vehicle's remote control key and the vehicle".

[0057] S122: Control the pressure buildup of the low-pressure oil pump according to the oil pressure and driving demand.

[0058] Controlling the low-pressure fuel pump's pressure buildup based on fuel pressure and driving demand may include: if the driving demand indicates a driving demand, determining a target condition based on the fuel pressure; and if the current vehicle status information meets the target condition, controlling the low-pressure fuel pump to start and build pressure in the fuel pipeline. Correspondingly, if the driving demand indicates no driving demand, controlling the low-pressure fuel pump's pressure buildup may be disabled.

[0059] Specifically, when there is a driving demand, if the oil pressure is high (e.g., greater than a preset high-pressure threshold), the engine can be successfully ignited on the first try. There is no need to pre-start the low-pressure oil pump to build pressure, and the vehicle can be controlled in the usual way. If the oil pressure is low (e.g., less than or equal to the preset high-pressure threshold), the low-pressure oil pump must be pre-started to build pressure so that the engine can be successfully ignited on the first try when starting the engine, reducing user waiting time and improving the driving experience. When there is no driving demand, the low-pressure oil pump can be prohibited from operating and building pressure to reduce ineffective operation of the low-pressure oil pump.

[0060] For example, when there is a driving demand and the oil pressure is low, in order to improve the accuracy of control, after receiving the vehicle unlocking signal, the vehicle status information can be continuously acquired and judged, and it can be determined whether it is necessary to pre-start the low-pressure oil pump to build pressure, and the best time to pre-start the low-pressure oil pump to build pressure (i.e., the target condition) to achieve the pre-pressure building demand and avoid unnecessary low-pressure oil pump operation as much as possible.

[0061] In some embodiments of the present application, determining the target condition based on the oil pressure includes: determining the target condition based on the interval in which the oil pressure is located. The interval can be pre-calibrated, fixed, customizable, or adjustable according to the vehicle state. Two or more intervals can be calibrated, for example, Figure 4 As shown, the calibration range includes no-pressure zone, low-pressure zone, under-pressure zone, and standard zone, and the corresponding oil pressure increases in sequence, that is, the oil pressure in the no-pressure zone is less than the oil pressure in the low-pressure zone, the oil pressure in the low-pressure zone is less than the oil pressure in the under-pressure zone, and the oil pressure in the under-pressure zone is less than the oil pressure in the standard zone. In addition, Figure 4 The figure also shows the change curve of oil pressure over time after the vehicle is parked.

[0062] In this embodiment, exemplarily, the vehicle status information also includes the distance between the vehicle's remote control key and the vehicle; the target condition is determined based on the oil pressure range, including: if the oil pressure is in a no-pressure zone, then the target condition is determined to be that the distance between the vehicle's remote control key and the vehicle is less than or equal to a target distance threshold.

[0063] Specifically, the distance between the remote control key and the vehicle can be Figure 2 The key detection module shown in the figure is detected. If the oil pressure is in the zero-pressure zone, it means that a longer pressure-building time is required. In this case, the target condition can be set more loosely. For example, if the distance is less than or equal to the target distance threshold, the user with the remote key is close to the vehicle and may intend to drive. To achieve timely pressure buildup, the low-pressure oil pump can be controlled to operate and build pressure when the distance is less than or equal to the target distance threshold to meet the subsequent rapid engine start requirement.

[0064] Exemplarily, the vehicle status information also includes the status of the vehicle's main driver's door; the target condition is determined based on the oil pressure range, including: if the oil pressure is in a no-pressure zone, then the target condition is determined to be that the main driver's door is in an open state.

[0065] Specifically, the driver's door status can be detected by an angle sensor installed in the driver's door. For example, if the opening angle of the driver's door is greater than a preset door opening angle threshold (which can be calibrated as needed, such as the minimum door opening angle for the driver to enter the vehicle), the driver's door is determined to be open. If the oil pressure is in the zero-pressure zone, indicating that a longer pressure build-up time is required, the target condition can be set to be more relaxed, such as the driver's door being open.

[0066] It should be noted that for vehicles equipped with a remote control key and the distance between the remote control key and the vehicle can be detected, when the oil pressure is in the no-pressure zone, two target conditions can be set. As long as the vehicle status information reaches one of them, pre-pressure building can be performed. For vehicles that are not equipped with a remote control key or the distance between the remote control key and the vehicle cannot be detected, when the oil pressure is in the no-pressure zone, one target condition and the above-mentioned main driver's door status condition can be set. In addition, if the distance is less than the target distance threshold, or the main driver's door is open, it means that the user may have a need to drive, but may not, such as just to pick up something, take a rest, etc. At this time, if the oil pressure is greater than the pressure in the no-pressure zone, it means that the pressure building time is shorter than that in the no-pressure zone, and the real-time vehicle status information can continue to be judged to reduce or avoid miscontrol of the low-pressure oil pump and reduce the ineffective operation of the low-pressure oil pump.

[0067] Exemplarily, the vehicle status information also includes whether there is a driver sitting in the main driver's seat of the vehicle; the target condition is determined based on the oil pressure range, including: if the oil pressure is in the low pressure zone, then the target condition is determined to be that there is a driver sitting in the main driver's seat.

[0068] Specifically, the main driver's seat occupant situation includes whether there is a driver sitting in the main driver's seat, which can be determined based on the camera device in the car (the collected image can be used to identify the age and identity information of the main driver's seat occupant to determine whether it is the driver, and whether the person is sitting in the main driver's seat) and / or Figure 2 The information collected by the main driver's seat pressure sensor is obtained. For example, if the pressure value collected by the main driver's seat pressure sensor is greater than a preset pressure threshold, or if the distribution of pressure values collected by the main driver's seat pressure sensor conforms to a preset distribution rule, it is determined that a driver is sitting in the main driver's seat. If the oil pressure is in the low pressure zone, the target condition can be determined to be a driver in the main driver's seat. It should be understood that the presence of a driver in the main driver's seat occurs after the remote control key is less than the target distance from the vehicle and the main driver's door is open, which is one step closer to starting the vehicle. Therefore, this target condition is more stringent than the target condition in the no-pressure zone. In addition, the presence of a driver in the main driver's seat indicates that the user may have a desire to drive, and the degree of desire may be higher than that corresponding to the main driver's door being open or the remote control key being less than the target distance threshold, but it may also be absent. When the oil pressure is greater than the oil pressure in the low pressure zone, to improve control accuracy, pre-pressurization can be skipped and real-time vehicle status information can be determined.

[0069] Exemplarily, the posture of the driver in the main driving seat and the posture of the main driving seat; determining the target condition based on the range of the oil pressure, including: if the oil pressure is in the low pressure zone, then determining the target condition as the posture of the main driving seat is in the first preset driving posture, and the posture of the driver in the main driving seat is in the second preset driving posture, wherein the posture of the main driving seat includes the front and rear position of the main driving seat and / or the backrest angle.

[0070] Specifically, the situation of the person in the main driver's seat can be obtained by the image captured by the camera device in the car. For example, the captured image can be recognized to identify the driver's posture; the main driver's seat position can be determined based on the image captured by the camera device in the car. Figure 2The target condition is obtained based on information collected by the driver's seat position sensor (which can detect the fore-and-aft position, height, and other conditions of the driver's seat) and the driver's seat backrest angle sensor. If the oil pressure is in the low pressure zone, the target condition can be set as follows: the difference between the driver's seat position and the target seat position is within a preset difference range (for example, the fore-and-aft position, height, and other conditions of the driver's seat are the same or similar to those under normal driving conditions, and the driver's seat backrest angle is the same or similar to that under normal driving conditions, thus satisfying the first preset driving posture), and the driver's seat occupant is in the second driving posture, meaning both the driver's seat and the driver are in the driving posture. Compared to the aforementioned "target condition of a driver in the driver's seat," this target condition is more stringent. Specifically, if the driver is seated in the driver's seat but in a non-driving posture, such as leaning over the steering wheel or leaning against the center console, the target condition is determined to be unsatisfied. This example provides more accurate driving demand determination, enabling better control over when to activate the low-pressure oil pump and whether to disable the low-pressure oil pump.

[0071] As an implementation method, when determining whether the vehicle status information meets the target conditions based on the situation of the occupant in the main driver's seat, or the situation of the occupant in the main driver's seat and the position of the main driver's seat, it is also necessary to determine that the remote control key (equipped and detectable) is in the vehicle and that all doors and trunks of the vehicle are in a closed state, thereby improving the reliability of control.

[0072] Exemplarily, the vehicle status information also includes the vehicle's seat belt status; determining the target condition based on the oil pressure range includes: if the oil pressure is in an underpressure zone, determining the target condition as at least one seat belt being in a locked state.

[0073] Specifically, the seat belt status can be detected by the seat belt switch. If the oil pressure is in the underpressure zone, the required pressure build-up time is shorter, and the target condition can be stricter to reduce or avoid miscontrol, such as determining that the target condition is that at least one seat belt is in a locked state (for example, the main driver's seat belt is in a locked state). It should be understood that the main driver's seat belt is in a locked state, indicating that the occupants of the vehicle are ready to ride and are likely to need to drive, that is, the degree of driving demand is relatively strong. This condition can be judged based on the above-mentioned distance being less than the target distance threshold, the main driver's door being in an open state, and the main driver's seat driver's condition and the main driver's seat posture being in a driving posture, thereby improving the reliability of control.

[0074] Exemplarily, the vehicle status information also includes the vehicle's brake pedal opening; determining the target condition based on the oil pressure range includes: if the oil pressure is in the underpressure zone, determining the target condition as the brake pedal opening being greater than the target opening threshold.

[0075] Specifically, for vehicles equipped with a push-button start feature, the engine must be started by depressing the brake pedal and pressing the push-button start switch. Therefore, for vehicles equipped with a push-button start feature, the vehicle status information may also include the brake pedal opening, which can be detected by a brake pedal sensor. If the oil pressure is in the underpressure zone, the required pressure build-up time is shorter, and the target condition can be more stringent to reduce or avoid erroneous control. For example, the target condition can be determined as the brake pedal opening being greater than a target opening threshold. It should be understood that when the brake pedal opening is greater than the target opening threshold, it indicates that the driver is ready to start the vehicle and is likely to drive, indicating a strong desire to drive. This condition can be determined based on the aforementioned distance being less than the target distance threshold, the main driver's door being open, and the main driver's seat and the main driver's seat being in the driving position. This can improve control reliability.

[0076] As an implementation method, when the seat belt locking state and the brake pedal opening simultaneously meet the corresponding target conditions, the low-pressure oil pump can be controlled to operate and build pressure, thereby improving the reliability of control and reducing or avoiding miscontrol.

[0077] Exemplarily, the vehicle status information also includes an engine ignition command of the vehicle; determining the target condition according to the interval of the oil pressure includes: if the oil pressure is in the standard area, determining the target condition as receiving the engine ignition command.

[0078] Specifically, the engine ignition command can be Figure 2 Ignition detection is shown. For example, when the driver starts the vehicle using the mechanical key (e.g., turning it to "START") or the push-to-start button (pressing it), the engine ignition command is detected. If the oil pressure is within the standard range, indicating high oil pressure and a short build-up time, even if the user urgently needs the vehicle, the driving experience will not be affected. The target condition is determined to be receipt of the engine ignition command.

[0079] In some examples, whether there is a driving demand can also be determined based on the real-time presence of a driver in the main driver's seat, the main driver's posture and main driver's seat posture, whether the main driver's seat belt is locked, whether the brake pedal opening is greater than the target opening threshold, and the main driver's door status. If there is no driving demand, such as the main driver's seat is not in a driving posture, the driver is not in a driving posture, or the main driver's seat belt is not locked, then even if the current vehicle status information meets the corresponding target conditions, the low-pressure oil pump is still prohibited from operating and building pressure, thereby preventing the low-pressure oil pump from operating effectively and improving vehicle safety. At the same time, a prompt message can also be issued (such as a prompt message issued based on the reason for determining that there is no driving demand) so that the user can correct improper vehicle operation, such as not wearing a seat belt or an inappropriate main driver's seat position.

[0080] The following combination Figure 2 、 Figure 5 The implementation process of the vehicle control method of the embodiment of the present application is explained through a specific embodiment.

[0081] The vehicle control method of the embodiment of the present application can be Figure 2 The system implementation shown is shown in Figure 2 The system includes an information acquisition module 21, an information processing module 22, and a fuel pump execution module 23. The information acquisition module 21 is used to collect sensor status signals (including vehicle unlocking instructions, vehicle status information, etc.) required during system operation and transmit them to the information processing module 22. After receiving the sensor status signals input by the information acquisition module 21, the information processing module 22 performs calculations based on a preset control strategy to generate instructions for controlling fuel pump operation, and transmits these instructions to the fuel pump execution module 23. After receiving the instructions from the information processing module 22, the fuel pump execution module 23 controls the operation of the low-pressure fuel pump, that is, starts to build pressure in the fuel pipeline.

[0082] Specifically, the information processing module 22 can be an independent controller hardware device (such as Figure 2 The oil pump controller shown, or the vehicle control device described below. Figure 2 The information collection module 21 includes: an engine control unit (ECU), a fuel pressure sensor, an oil level sensor, a brake pedal sensor, a vehicle control unit (VCU), a driver's seat position sensor, a driver's seat back angle sensor, a driver's seat pressure sensor, a driver's posture confirmation module, an ignition device (button / key), a body control unit, a driver's door lock switch, a passenger door lock switch, a rear door lock switch, a trunk door lock switch, a driver's seat belt switch, a key detection module, and a multimedia system navigation app module. Of course, the information collection module 21 may also include other devices for collecting vehicle status information, such as on-board radars and infrared sensors. See Figure 2 The oil pump execution module 23 includes: an oil pump controller unit, an oil pump relay, a low-pressure oil pump and other devices, which are used to execute the control command of the low-pressure oil pump.

[0083] Figure 2 The working process of the system shown is:

[0084] The body control unit detects the vehicle unlocking event (i.e., receives the vehicle unlocking command) through the CAN line and immediately sends a signal to the ECU; the ECU immediately sends a command to the fuel pressure sensor to detect the residual fuel pressure (i.e., oil pressure) in the fuel line, and then determines the level of the residual fuel pressure based on the preset threshold; the residual fuel pressure level in the fuel line can be divided into four states: standard zone, underpressure zone, low pressure zone, and no pressure (e.g., Figure 4 The above status information is transmitted to the information acquisition module via the CAN line.

[0085] The information acquisition module 21 also monitors and collects the status of other components and sensors, such as the distance between the remote control key (such as a Bluetooth key) and the vehicle, the main driver's door switch status, the main driver's seat occupant, the main driver's seat position, the main driver's seat back angle, the driver's posture, the brake pedal status, the one-button start command (i.e., the engine ignition command), and other parameters. The status signals of all components are transmitted to the information processing module 22 through the CAN line. After obtaining the above status information, the information processing module 22 can Figure 6 The control flow shown and the control strategy shown in Table 1 determine whether to pre-start the low-pressure fuel pump to pre-build fuel pressure, and if so, control the low-pressure fuel pump to run and build pressure, so that when the engine ignition command is received, the engine can be successfully ignited in a shorter time without affecting the driving experience; and if not, prohibit the control of the low-pressure fuel pump to run and build pressure, so as to reduce the ineffective operation of the low-pressure fuel pump and reduce energy consumption.

[0086] Table 1

[0087]

[0088]

[0089] In Table 1, a is the target distance threshold, which may be expressed in meters. The black circle indicates that there is a corresponding relationship between the oil pressure level and the target condition.

[0090] It should be noted that the vehicle status information collected by the information collection module 21 includes but is not limited to Figure 2 The information shown may also include other information, such as vehicle voice control commands and gesture control commands, and can be increased or decreased as needed. The above oil pressure range division is illustrative only; different oil pressure ranges can be set during actual development based on the actual product characteristics. Furthermore, for cost control reasons, the information processing module 22 can be integrated into other controllers, such as the VCU, ECU, or body control unit.

[0091] The following describes the beneficial effects of the vehicle control method of the embodiment of the present application for a vehicle with a mechanical key rotation start and a vehicle with a one-button start configuration:

[0092] 1) For vehicles with mechanical key rotation start

[0093] It can start working when the vehicle is remotely unlocked. By judging the oil pressure in the fuel line when unlocking, combined with real-time monitoring of parameters such as the distance from the remote control key to the vehicle, the door switch status, the main driver's seat status, and the driver's status, it can determine a reasonable time to pre-start the low-pressure oil pump. Even if the user is in a hurry to use the car (insert the mechanical key and turn it directly to "START"), the low-pressure oil pump can be pre-started in time to build up sufficient pressure to ensure the first successful engine ignition and enhance the user's driving experience. At the same time, it can also predict whether there is a need to drive, so as to reduce the ineffective operation of the low-pressure oil pump when the user has no need to drive.

[0094] 2) For vehicles with one-button start configuration

[0095] It can also start working when the vehicle is remotely unlocked. By determining the oil pressure in the fuel line during unlocking, combined with real-time monitoring of parameters such as the distance from the remote key to the vehicle, the door switch status, the main driver's seat status, and the driver's status, it can more accurately predict the start of the vehicle, greatly reducing the ineffective operation of the low-pressure oil pump when the user does not need to drive the vehicle. For example, if the user simply wants to open the door to take out an item, take a nap on the seat, open the trunk to put in / take out luggage, etc., the system of this technical invention will start the oil pump to avoid ineffective operation of the oil pump, which not only eliminates the noise and vibration of the oil pump during operation, but also reduces power consumption, improving the economy of the entire vehicle to a certain extent. In addition, a reasonable time can be determined to pre-start the low-pressure oil pump so that when the one-button start switch is pressed later, the engine can be successfully ignited in one go.

[0096] It can be seen that the vehicle control method of the embodiment of the present application can not only solve the problem that the key of a vehicle with a mechanical key configuration skips the "ON" position and is directly turned to the "Start" position and the oil pressure cannot be pre-established in time, but also eliminate the invalid starting of the low-pressure oil pump and the accompanying noise and vibration problems caused by unlocking without driving requirements in a vehicle with a one-button start configuration, and can also reduce energy consumption and improve the economy of the entire vehicle to a certain extent.
