[0048] In order to make the purpose, technical scheme and advantages of the embodiments of the present disclosure clearer, the technical scheme in the embodiments of the present disclosure will be clearly and completely described below in conjunction with the drawings in the embodiments of the present disclosure. Obviously, the described embodiments are only part of the embodiments of the present disclosure, rather than all of the embodiments. The components of the embodiments of the present disclosure generally described and shown here can be arranged and designed in various different configurations. Therefore, the following detailed description of the embodiments of the present disclosure is not intended to limit the scope of the present disclosure claimed for protection, but merely represents the selected embodiments of the present disclosure. Based on the embodiments of the present disclosure, all other embodiments obtained by those skilled in the art without making creative work belong to the scope of protection of the present disclosure.

[0049] Research has found that since the active air intake grille is usually located at the front of the vehicle, it is easy to inhale foreign matter and cause failure of the active air intake grille. Mechanical jamming and stalling may occur, resulting in the inability to meet the optimal opening requirements of the blades. In more serious cases, the failure to open the blades in time may cause the vehicle to stall and thermal runaway. The active air intake grille needs to be monitored and controlled reasonably.

[0050] Based on the above research, the present disclosure provides a vehicle active air intake grille control method and a vehicle, which can determine the power-off type of the vehicle when it was powered on last time after the vehicle is powered on and started, and judge whether the active air intake grille needs to be reset according to the power-off type. When the opening information of the active air intake grille can be obtained (normal power-off), the active air intake grille is not reset, and when the opening information of the active air intake grille cannot be obtained (forced power-off), the active air intake grille is reset, thereby reducing the reset frequency of the active air intake grille, avoiding frequent active air intake grille reset, and improving the user's riding experience.

[0051] The defects existing in the above solutions are the results obtained by the inventor after practice and careful research. Therefore, the discovery process of the above problems and the solutions proposed by the present disclosure for the above problems below should be the contributions made by the inventor to the present disclosure during the disclosure process.

[0052] It should be noted that similar reference numerals and letters denote similar items in the following drawings, and therefore, once an item is defined in one drawing, further definition and explanation thereof is not required in subsequent drawings.

[0053] To facilitate understanding of this embodiment, the application scenario of the embodiment of the present disclosure is first introduced in detail. The embodiment of the present disclosure can be applied to vehicles. Figure 1 as well as Figure 2 The shown are respectively a schematic diagram of a vehicle provided by some embodiments of the present disclosure, and a functional schematic diagram of a vehicle provided by some embodiments of the present disclosure. Figure 1 The vehicle is equipped with an active air intake grille, which is located at the front of the vehicle, in front of the vehicle engine. The active air intake grille can include components such as a control module, a grille panel, an electric motor, and a drive device. The vehicle can use the information obtained by the sensor to control the active air intake grille, and automatically adjust the opening and closing degree of the grille according to information such as vehicle speed, engine temperature, and air temperature, thereby achieving functions such as improving fuel economy, optimizing aerodynamic performance, engine temperature management, and controlling noise and vibration. Figure 2 Taking the vehicle in the embodiment as an example, the vehicle in the embodiment of the present disclosure may include a body domain controller, a heat pump module, an active air intake grille module (a control module of the active air intake grille), a cockpit domain controller, and a central control console. The body domain controller and the heat pump module may communicate via a controller area network (CAN), the heat pump module and the active air intake grille module may communicate via a local interconnect network (LIN), and the body domain controller and the active air intake grille module and the central control console may also communicate. The body domain controller may issue control instructions to the active air intake grille module via the heat pump module, and may also receive information fed back by the active air intake grille via the heat pump module. The active air intake grille module may also directly send feedback information to the body domain controller, and the body domain controller may display prompt information via the central control console.

[0054] See also Figure 3 FIG. 1 is a flow chart of a method for controlling an active air intake grille of a vehicle provided by an embodiment of the present disclosure, and the method includes:

[0055] S301. In response to a vehicle being powered on and started, determining a power-off type of the vehicle when it was powered off last time; the power-off type includes forced power-off and normal power-off; and recording the opening information of the active air intake grille in the vehicle when the power is normally turned off.

[0056] The vehicle in the embodiments of the present disclosure may refer to a hybrid vehicle, an electric vehicle, a fuel vehicle, etc. The above-mentioned vehicle power-on start may refer to activating the vehicle's electrical system, such as the driver pressing a start button, rotating an ignition switch, swiping a card to unlock, and the like.

[0057] Powering down a vehicle is the process of disconnecting the vehicle's electrical system from power or shutting down the battery. Specifically, it disconnects the vehicle's electrical system from the battery and other power sources to stop the operation of the electrical components. Powering down usually occurs when the vehicle is turned off or shut down, and it is done to save energy, protect the battery, or ensure that the vehicle is no longer consuming electricity.

[0058] The vehicle power-off process may include steps such as shutting down the vehicle power, shutting down the electronic control unit, disconnecting the battery, shutting down the engine and conducting a safety check. The vehicle power-off types may include normal power-off and forced power-off. Normal power-off may refer to power-off performed according to preset steps, and forced power-off may include abnormal power-offs such as plugging in and out a small battery and abnormal power-off.

[0059] In the disclosed embodiment, when the active air intake grille in the vehicle is normally powered off, the opening information of the active air intake grille when powered off can be recorded for use after the vehicle is powered on again. When the vehicle is forcibly powered off, the active air intake grille is usually suddenly powered off and the opening information cannot be recorded. The opening information of the active air intake grille cannot be obtained after the vehicle is powered on again.

[0060] S302: Based on the power-off type, determine whether it is necessary to reset the active air intake grille in the vehicle.

[0061] When the vehicle controls the active air intake grille, it is usually necessary to determine the current opening information of the active air intake grille, and then determine the command signal for controlling the active air intake grille based on the current opening information. If the active air intake grille cannot record the opening information when the power is off, the active air intake grille needs to be reset. Therefore, it can be determined whether a reset command needs to be sent to the active air intake grille in the vehicle based on the power-off type.

[0062] Exemplarily, when the power-off type indicates that the last power-off of the vehicle was forced, and when the power-off type indicates that the last power-off of the vehicle was normal, and the opening information of the active air intake grille in the vehicle recorded at the last power-off is not found, it is determined that the active air intake grille needs to be reset.

[0063] When the vehicle is normally powered off, the active air intake grille will record the opening information when the power is turned off. However, in some cases, the opening information may not be stored correctly, or the opening information may be lost after being successfully stored. At this time, the active air intake grille can be reset to restore the opening of the active air intake grille to its initial state.

[0064] Therefore, when the vehicle is normally powered off, you can first query the opening information of the active air intake grille recorded when the power was last turned off. If the opening information recorded when the power was last turned off is queried, it can be determined that the active air intake grille does not need to be reset; if the opening information recorded when the power was last turned off is not queried, it can be determined that the active air intake grille needs to be reset.

[0065] In a possible implementation, the above step of determining whether the active air intake grille needs to be reset may be performed by a body domain controller in the vehicle, or by an active air intake grille module, or by other control modules or devices independent of the body domain controller and the active air intake grille.

[0066] S303: When the judgment result indicates that the active air intake grille needs to be reset, a reset instruction is sent to the active air intake grille, and reset response information sent by the active air intake grille is obtained.

[0067] After obtaining the judgment result, if the judgment result indicates that the active air intake grille needs to be reset, step S303 can be executed. Specifically, a reset instruction can be sent to the active air intake grille to reset the active air intake grille autonomously and return reset response information.

[0068] In a possible implementation, the reset instruction of the active air intake grille can be sent by the vehicle body domain controller. When the active air intake grille determines that it needs to be reset, it can send a reset request to the vehicle body domain controller. After obtaining the reset request, the vehicle body domain controller can feedback the reset instruction to the active air intake grille. Alternatively, the reset instruction of the active air intake grille can be directly sent by the active air intake grille module to the mechanical structure of the active air intake grille. The mechanical structure of the active air intake grille can respond to the reset instruction of the active air intake grille module to reset and feedback reset response information.

[0069] When the judgment is performed by the body domain controller, the body domain controller can directly send a reset instruction to the active air intake grille.

[0070] After sending a reset instruction to the active air intake grille, the reset response information fed back by the active air intake grille can be obtained. The reset response information can indicate whether the active air intake grille is successfully reset. When the reset response information indicates that the active air intake grille is not successfully reset, the reset instruction can continue to be sent to the active air intake grille, so that the active air intake grille is repeatedly reset until the reset is successful.

[0071] In one possible implementation, reset instructions of different torque levels may be sent to the active air intake grille in sequence until reset response information corresponding to the reset instructions is obtained indicating that the active air intake grille is successfully reset; among the reset instructions of different torque levels, the rotational torque indicated by the reset instruction of the previous torque level is lower than the rotational torque indicated by the reset instruction of the next torque level.

[0072] Normally, if the active air intake grille fails to reset successfully, it may be because foreign matter has been sucked into the active air intake grille and has stuck the grille panel of the active air intake grille. In this case, the rotational torque of the active air intake grille during resetting can usually be increased, thereby increasing the force exerted by the active air intake grille on the foreign matter and expelling the foreign matter.

[0073] In this step, if the active air intake grille fails to be reset successfully, a reset command of the next torque level can be sent to the active air intake grille, so that the active air intake grille is reset using a higher rotation torque to discharge the foreign matter. If the reset is still not completed, a reset command of an even lower torque level can be sent to reset using a higher rotation torque.

[0074] For example, the torque levels may include a first torque level, a second torque level, and a third torque level. The first torque level may correspond to a rotational torque of 1.6 Nm, the second torque level may correspond to a rotational torque of 2.0 Nm, and the third torque level may correspond to a rotational torque of 2.4 Nm.

[0075] In some cases, a reset at a torque level may not be able to expel foreign matter, while frequently increasing the rotational torque may cause damage to the active air intake grille. Therefore, for each of the different torque levels, a reset instruction of the torque level may be sent to the active air intake grille multiple times until the reset response information indicates that the active air intake grille is successfully reset, or the number of times the reset instruction of the torque level is sent to the active air intake grille reaches a preset number threshold corresponding to the torque level.

[0076] Exemplarily, after sending a reset instruction for a certain torque level, if the reset fails, the reset instruction for this torque level can be sent repeatedly. When the number of times the reset instruction for this torque level is sent reaches a preset number threshold corresponding to the torque level, if the reset still fails, the reset instruction for the next torque level is sent to the active air intake grille.

[0077] The preset number thresholds corresponding to different torque levels may be the same or different. For example, the preset number thresholds corresponding to each torque level may be set according to the rotation torque corresponding to the torque level. For example, the preset number threshold corresponding to the first torque level with a lower rotation torque may be 6, the preset number threshold corresponding to the second torque level with a medium rotation torque may be 4, and the preset number threshold corresponding to the third torque level with a higher rotation torque may be 2. For another example, the preset number thresholds for each of the above torque levels may be directly set to 4.

[0078] After sending reset instructions of different torque levels to the active air intake grille in sequence, if the reset response information obtained still indicates that the active air intake grille has not been successfully reset, a warning message may be displayed through the central console of the vehicle.

[0079] The center console refers to the control area between the driver's seat and the front passenger seat. It is usually used to install and operate various functional control devices, such as entertainment systems, air conditioning, driving mode selection, storage space, etc., for the convenience of the driver and front passenger.

[0080] The above-mentioned warning information may include image information indicating that an abnormality has occurred in the position of the active air intake grille in the vehicle, and / or text information indicating that an abnormality has occurred in the active air intake grille.

[0081] For example, the central console can display the body image and highlight the area of ​​the active air intake grille in the body image. It can also be equipped with text messages such as "The active air intake grille is abnormal, please conduct an external check or go to the 4S shop for maintenance."

[0082] Exemplarily, the body domain controller or the active air intake grille (active air intake grille module) can send an alarm instruction or an alarm signal to the cockpit domain controller. After receiving the alarm instruction or the alarm signal, the cockpit domain controller can control the central console to display the alarm information.

[0083] In order to avoid frequent false alarms, alarm conditions can be set for the alarm. After reset instructions of different torque levels are sent to the active air intake grille in sequence, the alarm information will be displayed through the central console of the vehicle only when the reset response information obtained still indicates that the active air intake grille has not been successfully reset and the alarm conditions are met.

[0084] The above alarm conditions may include at least one of the following:

[0085] Acquiring a fault signal indicating that the active air intake grille is blocked;

[0086] Acquiring a fault signal indicating that the active air intake grille has over-traveled;

[0087] A preset time length has passed since the time point when the judgment result is determined to be obtained.

[0088] The above fault signal may be sent by the active air intake grille. The active air intake grille may be blocked and cannot continue to rotate; the active air intake grille may have an overtravel, which may mean that the actual travel of the motor of the active air intake grille is greater than or less than the target travel and cannot be positioned to the target position or opening.

[0089] In a possible implementation, the preset time length may be 170 seconds. When determining whether an alarm condition is met, the alarm information may be displayed only after each alarm condition is met, or the alarm information may be displayed when any alarm condition is met.

[0090] In one possible implementation, the body domain controller may send a reset command only once. After the active air intake control module fails to reset, it may automatically perform a new reset. After the number of reset failures reaches a preset threshold, it may directly use the next torque level of rotational torque for reset until the reset is successful or the cutoff condition is met.

[0091] S304. When the reset response information indicates that the active air intake grille is successfully reset, or when the judgment result indicates that the active air intake grille does not need to be reset, a control instruction for the active air intake grille is determined based on the opening information of the active air intake grille and the operating status information of the vehicle, and the control instruction is sent to the active air intake grille; the control instruction is used to control the rotational torque and opening of the active air intake grille.

[0092] In this step, when the reset response information indicates that the active air intake grille is successfully reset, it can be determined that the function of the active air intake grille is normal, and the initial position of the active air intake grille can be directly used as the opening information of the active air intake grille. Based on the opening information and the operating status information of the vehicle, the control instruction for the active air intake grille can be determined, and the control instruction is sent to the active air intake grille, so that the active air intake grille rotates to the set opening with the set rotational torque.

[0093] If the judgment result indicates that the active air intake grille does not need to be reset, the active air intake grille can be directly controlled by using the queried opening information of the active air intake grille when the power was last turned off and the vehicle's operating status information.

[0094] When the vehicle is driving normally, if a fault signal of the active air intake grille is obtained, a reset command can be directly sent to the active air intake grille. The method of sending the reset command to the active air intake grille at this time can refer to the method of sending the reset command when the vehicle is powered on.

[0095] The above fault signal may include at least one of the following:

[0096] A fault signal indicating that the active air intake grille is blocked;

[0097] A fault signal indicating that the active air intake grille has over-traveled;

[0098] A fault signal indicating an electronic fault of the active grille.

[0099] The vehicle active air intake grille control method provided by the embodiment of the present disclosure can determine the power-off type of the vehicle when it was powered on last time after the vehicle is powered on and start, and judge whether the active air intake grille needs to be reset according to the power-off type. When the opening information of the active air intake grille can be obtained (normal power-off), the active air intake grille is not reset, and when the opening information of the active air intake grille cannot be obtained (forced power-off), the active air intake grille is reset, thereby reducing the resetting frequency of the active air intake grille, avoiding frequent active air intake grille resetting, and improving the user's riding experience.

[0100] See also Figure 4As shown, it is a flow chart of another vehicle active air intake grille control method provided by some embodiments of the present disclosure. In this method, first respond to the vehicle swiping card to unlock and power on, and then press whether the vehicle is in a normal power-on and power-off state. If the vehicle is in a normal state (that is, it is powered on and off normally by swiping a card, key, etc.), the active air intake grille can be controlled to retrieve the opening information (or position information) stored in the last working state; if the vehicle is in an abnormal state of abnormal power on and off such as plugging in and out of a small battery, abnormal power failure, etc., the active air intake grille loses its last working position, and a self-learning (that is, the above-mentioned reset) request can be sent to the control module (such as the active air intake grille module, the body domain controller or other control module). After receiving the self-learning request, the control module can send a self-learning instruction (that is, a reset instruction). When the vehicle is in a normal state, if the position information in the last working state fails to be retrieved, the active air intake grille self-learning can also be triggered. After self-learning is triggered, if the self-learning is successful, the active air intake grille is reset, and the control module can send control instructions to the active air intake grille according to the vehicle's front cabin status after coupling, such as the vehicle's driving speed, fan speed, and water tank temperature, so that the active air intake grille can work normally; if the self-learning fails, a self-learning failure signal can be generated to display an alarm message. After successfully reading the position information of the active air intake grille during the last operation, you can also wait for the control module to send a control signal to make the active air intake grille work normally. When the active air intake grille works normally, the vehicle can enter a normal driving state.

[0101] See also Figure 5 As shown, it is a flow chart of triggering the reset of the active air intake grille when the vehicle is started, provided by some embodiments of the present disclosure. In this process, the active air intake grille receives a self-learning instruction (i.e., a reset instruction) and starts to reset. When the reset attempt fails for four consecutive times, the control module can send a new self-learning instruction to the active air intake grille, and the new self-learning instruction adopts the rotation torque of the next torque level. After the self-learning of each torque level is still unsuccessful, the control module can determine whether the cut-off condition is met. The cut-off condition may include detecting a fault signal of a stall of the active air intake grille, detecting a fault signal of an over-travel of the active air intake grille, and a preset time length from the time when the self-learning starts. When the cut-off condition is met, the alarm information can be displayed through the central console.

[0102] See also Figure 6 The figure shows a flow chart of triggering the reset of the active air intake grille when the vehicle is driving normally provided by some embodiments of the present disclosure. In this flow chart, when the vehicle is driving normally after power-on, if a fault signal indicating that the active air intake grille is blocked, a fault signal indicating that the active air intake grille has overtraveled, or a fault signal indicating that the active air intake grille has an electronic fault is detected, the self-learning of the active air intake grille can be triggered.

[0103] Those skilled in the art will appreciate that, in the above method of specific implementation, the order in which the steps are written does not imply a strict execution order and does not constitute any limitation on the implementation process. The specific execution order of the steps should be determined by their functions and possible internal logic.

[0104] Based on the same inventive concept, the embodiment of the present disclosure also provides a vehicle active air intake grille control device corresponding to the vehicle active air intake grille control method. Since the principle of solving the problem by the device in the embodiment of the present disclosure is similar to the above-mentioned vehicle active air intake grille control method in the embodiment of the present disclosure, the implementation of the device can refer to the implementation of the method, and the repeated parts will not be repeated.
