[0029] Embodiments of the present invention are described in detail below, examples of which are illustrated in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain the present invention, and should not be construed as limiting the present invention.

[0030] The electric air outlet control method, electric air outlet control device, and vehicle proposed in the embodiments of the present invention are described below with reference to the accompanying drawings.

[0031] Figure 1 This is a flowchart of an electric air outlet control method according to an embodiment of the present invention.

[0032] In one embodiment of the present invention, the electric air outlet includes a drive motor.

[0033] Specifically, the drive motor in the electric air vent can be a LIN stepper motor to rotate the air vent blades. Taking the application of electric air vents in vehicles as an example, such as... Figure 2As shown, the vehicle has 4 electric air outlets in common, each of which is divided into left and right blades and upper and lower blades, and a total of 8 drive motors (outlet motor 1, outlet motor 2, outlet motor 3, outlet motor 4, outlet motor 5, outlet motor 6, outlet motor 7, outlet motor 8). The CEM (Central Electronic Module) in the vehicle controls the operation of the drive motor through the LIN (Local Interconnect Network) communication mode, and reads the operating state of the drive motor in real time.

[0034] Next, taking the CEM of the vehicle as an example, the electric air outlet control method of the present application is described in detail in combination with the drawings.

[0035] As shown in the drawings, Figure 1 The electric air outlet control method of the embodiment of the present application can include:

[0036] S1, in response to the power-on instruction, the drive motor is monitored online;

[0037] S2, in the case where the drive motor is in an online state, the starting position of the drive motor is determined;

[0038] S3, in the case where the target start instruction is received, the drive motor is driven based on the starting position to control the electric air outlet.

[0039] Specifically, the power supply of the electric air outlet is KL30, and is controlled by the CEM through a high-side switch or a relay, and is supplied to the electric air outlet after filtering. The power-on and working process of the electric air outlet is as shown in the drawings. Figure 3 Among them, t0: CEM initialization time; t1: relay attraction through filter, voltage rise time; t2: drive motor initialization time, t1+t2 is recommended to reserve 100ms, that is, CEM controls the relay attraction for 100ms, and then sends LIN control to drive the motor to operate; t3: outlet working; t4: relay disconnection to motor complete power-off end.

[0040] After the electric air outlet is powered on, the CEM (Continuous Engine Management) performs online monitoring of the drive motors. For example, it determines the online status of the drive motors based on the acquisition of flag bits. When it is confirmed that all drive motors are online, the starting position of the drive motors is determined, thereby completing the initialization control of the drive motors. Then, upon receiving the target start command, the drive motors are driven according to their starting positions, thereby controlling the electric air outlet to ensure that the target air outlet control effect can be achieved based on the preset control program. The power-on command can be detected when the electric air outlet is powered on, or it can be detected when the user triggers the power-on button, based on button settings. The starting position of the drive motor is the initial position at which the drive motor starts running. This starting position can be the current position of the drive motor detected when the electric air outlet is powered on, or it can be a preset reference position. That is, after the electric air outlet is powered on, the drive motor is controlled to run to the preset reference position, which is used as the starting position of the drive motor. Specifically, the position can be represented by the rotor angle of the drive motor.

[0041] Therefore, upon power-on, this embodiment first performs initial control of the drive motor based on online monitoring and initial position confirmation to ensure effective control of the electric air outlet. Confirming the initial position of the drive motor can involve obtaining its current position or adjusting it to a default position; the specific method is not limited.

[0042] In one embodiment of the present invention, online monitoring of the drive motor includes: sending first target information to the drive motor so that the drive motor can adjust its state based on the first target information; obtaining the current flag information of the state flag bit of the drive motor, and determining that the drive motor is in an online state when the current flag information is consistent with the target flag information.

[0043] Specifically, the status flag is used to characterize the online status of the drive motor. Taking the reset flag as an example, after the drive motor is initially powered on, it sets the reset flag to 1. The motor can only operate normally after the flag is cleared to 0. That is, when the reset flag is 1, the drive motor is not online; when the reset flag is 0, the drive motor is online. Therefore, after the CEM is initially powered on, it sends the first target information to the drive motor so that the drive motor clears the 1d reset flag to 0 based on the first target information. After a preset time after sending the first target information, the CEM retrieves the reset flag of the drive motor. When the reset flag is 0, the drive motor is online; when the reset flag is 1, the drive motor is still offline. The example of the target flag being 0 is only one possible implementation method in this application; the specific implementation can be set according to the actual situation.

[0044] It should be noted that in addition to the above state flag bit including the reset flag bit, a stall flag bit, an emergency flag bit, etc. can also be included, and the specific implementation is not limited. It should be further noted that the reset flag bit refers to setting a specific flag bit to determine whether the reset operation of the driving motor needs to be performed. For example, when the reset flag bit is 1, the CEM sends the first target information, so that the motor driver resets the position parameter of the driving motor to the initial value based on the first target information, thereby realizing the function of resetting and finding the zero point, to ensure that the driving motor can be accurately positioned and controlled when performing the task, and the required accuracy is realized. The stall flag bit refers to setting a specific flag bit to determine whether the driving motor is stalled. For example, if the driving motor still outputs torque when the speed of the driving motor is 0 revolutions, it is determined that the driving motor is in a stall state, and the stall flag bit is set to 1. At this time, the CEM sends the first target information, so that the motor driver can perform stall processing based on the first target information, so that the stall flag bit is 0. The emergency flag bit can be used to indicate specific operations or states in an emergency, such as emergency stop protection state, the position parameter of the motor driver is reset to the initial value in an emergency, etc. The specific implementation can be set according to the actual situation.

[0045] The driving motor can adjust the state flag bit based on the first target information to complete the online of the driving motor.

[0046] In an embodiment of the present application, before the first target information is sent to the driving motor, the electric air outlet control method further comprises: obtaining initial flag information of the state flag bit of the driving motor, and when the initial flag information is consistent with the target flag information, determining that the driving motor is in an online state, and when the initial flag information is inconsistent with the target flag information, sending the first target information to the driving motor.

[0047] Specifically, the online monitoring of the driving motor can include two ways of calibration method and detection method.

[0048] For example, when the calibration method is used to monitor the driving motor online, the specific implementation is as follows: after the CEM controls the relay to be attracted and power is supplied to the driving motor, the CEM starts to send the first target information after the driving motor is powered on for 100 ms, so that the driving motor adjusts the state based on the first target information, so that the driving motor is in an online state. After detecting that the reset flag bit, the stall flag bit and the emergency flag bit are all equal to 0, the CEM determines that the driving motor is in an online state.

[0049] In the on-line monitoring of the driving motor by using the detection method, specifically, the CEM controls the relay to be attracted and to supply power to the driving motor. After the driving motor is powered on for 100 ms, the CEM starts to read the initial flag information of the state flag bit of the driving motor. When the CEM detects that the reset flag bit, the stall flag bit and the emergency flag bit of the motor are equal to 1 (or any one flag bit is equal to 1), the first target information is sent to clear the three flag bits synchronously. After detecting that the reset flag bit, the stall flag bit and the emergency flag bit are all equal to 0, the CEM determines that the driving motor is in the on-line state.

[0050] It can be understood that the sending of the first target information and the on-line state detection of the driving motor can be performed multiple times to realize redundant control, and the upper limit of the number of times is set. If the driving motor is still not on-line when the upper limit of the number of times is reached, a fault reminder is sent.

[0051] In an embodiment of the present application, the current flag information of the state flag bit of the driving motor is obtained, and the method further comprises: in the case that the feedback information sent by the driving motor is received within the preset time, determining the current flag information of the state flag bit of the driving motor based on the feedback information; in the case that the feedback information sent by the driving motor is not received within the preset time, determining that the driving motor communication is lost.

[0052] In an embodiment of the present application, the electric air outlet control method further comprises: in the case that the current flag information is inconsistent with the target flag information, determining that the driving motor communication is abnormal.

[0053] That is, the timing starts after the first target information is sent. If the feedback information of the driving motor is received within the preset time, the feedback information is valid, and the current flag information of the state flag bit of the driving motor is determined based on the feedback information. If the feedback information sent by the driving motor is not received within the preset time, it is determined that the driving motor communication is lost.

[0054] After the current flag information is determined based on the feedback information received within the preset time, if the current flag information is consistent with the target flag information, it is determined that the driving motor is on-line; if the current flag information is inconsistent with the target flag information, it is determined that the driving motor communication is abnormal.

[0055] In the case that the driving motor communication is abnormal or the driving motor communication is lost, the first target information can be sent to the driving motor again. If the current flag information consistent with the target flag information is not obtained after the first target information is sent multiple times, it is considered that the driving motor is not on-line, and a fault reminder is sent. The specific number of times of sending can be set based on the actual situation.

[0056] In the case that the driving motor is on-line, the determination of the initial position of the driving motor is performed. In the case that the driving motor is on-line, the determination of the initial position of the driving motor is performed.

[0057] In one embodiment of the present application, determining the starting position of the driving motor comprises: when the driving motor is powered on for the first time or when the driving motor is powered on for the second time and the pre-stored position corresponding to the driving motor is invalid, controlling the driving motor to perform a position zeroing and taking the current position of the driving motor after the position zeroing as the starting position of the driving motor; when the driving motor is powered on for the second time and the pre-stored position of the driving motor is valid, taking the pre-stored position as the starting position of the driving motor.

[0058] That is, when the driving motor is powered on for the first time, the position of the driving motor may deviate from the blade position of the electric air outlet, i.e., deviate from the zero position set in the preset air outlet control program, so the driving motor is controlled to perform a position zeroing when the driving motor is powered on for the first time, and the current position of the driving motor after the position zeroing is taken as the starting position of the driving motor.

[0059] When the driving motor is powered on for the second time and the pre-stored position of the driving motor is valid, the pre-stored position is directly taken as the starting position of the driving motor. The pre-stored position is the stop position of the driving motor at the end of the last operation.

[0060] When the driving motor is powered on for the second time but the pre-stored position corresponding to the driving motor is invalid, the driving motor also needs to be controlled to perform a position zeroing, and the current position of the driving motor after the position zeroing is taken as the starting position of the driving motor.

[0061] The position zeroing refers to moving the rotor of the driving motor to a specific starting position, which is usually taken as the reference zero position of the driving motor and used for subsequent position control and measurement to ensure that the motor can accurately respond to the control signal and achieve precise position control. In addition, the reference zero position of the driving motor corresponds to the position of the air outlet blade to ensure that the driving motor is controlled to achieve precise control of the air outlet blade during the operation of the electric air outlet and improve the control effect.

[0062] In one embodiment of the present application, the electric air outlet control method further comprises: when the driving motor is powered on for the first time and the position zeroing is completed, increasing the number of power-on operations of the driving motor by one.

[0063] That is, since the driving motor can be directly determined the starting position based on the pre-stored position when the driving motor is powered on for the first time, the number of power-on operations of the driving motor is incremented by one in the case that the driving motor is powered on for the first time and the position zeroing is completed, so as to prevent the driving motor from being mistaken as powered on for the first time when powered on next time and triggering the zeroing action. The power-on operation refers to the power-on of the electric air outlet and the receiving of the air outlet opening operation instruction. When the electric air outlet is powered on and the air outlet opening operation instruction is received, the number of power-on operations is incremented by one, and whether it is powered on for the first time can be determined based on the number of power-on operations.

[0064] If the driving motor is powered on for the first time and the position zeroing fails, the number of power-on operations of the driving motor is kept as 0, so as to ensure that the zeroing operation is continued to be performed when powered on next time and the control effect of the electric air outlet is ensured. For example, in the case of a hardware failure of the driving motor, the driving motor cannot perform the zeroing operation according to the zeroing control instruction, so that the driving motor fails to zero. Alternatively, the driving motor has a communication failure, so that the driving motor cannot receive the zeroing control instruction, and thus the driving motor fails to zero.

[0065] In addition, the zeroing result of the driving motor can also be indicated by a corresponding state bit, and the zeroing result can be identified by reading the zeroing state bit. For example, when the zeroing state bit of the driving motor is 0, it is determined that the zeroing is successful; when the zeroing state bit of the driving motor is 1, it is determined that the zeroing fails; and when the zeroing state bit of the driving motor cannot be identified, it is considered that the driving motor fails to zero.

[0066] In an embodiment of the present application, during the driving of the driving motor based on the starting position, the electric air outlet control method further comprises: in response to a target stop instruction, controlling the driving motor to stop running and obtaining the current position of the driving motor, taking the current position of the driving motor as the pre-stored position of the driving motor when powered on next time; or in response to a stop instruction, controlling the driving motor to stop running after running to a target stop position, and taking the target stop position as the pre-stored position of the driving motor when powered on next time.

[0067] Specifically, before the driving motor is powered off and stopped after receiving the target stop instruction, the driving motor can be directly controlled to stop running completely when the target stop instruction is received, and the current position of the driving motor is recorded, so as to facilitate the current position to be directly assigned to the starting position of the driving motor next time the driving motor is powered on. Alternatively, the driving motor can be uniformly driven to the target stop position and then stopped running after receiving the target stop instruction, so as to facilitate the target stop position to be directly assigned to the starting position of the driving motor next time the driving motor is powered on. The target stop position can be set based on the air outlet angle, for example, the target stop position can be determined based on the air outlet angle in the closed state.

[0068] As a specific embodiment of the present application, as shown in Figure 4 the electric air outlet control method can include the following steps:

[0069] S101, power on the electric air outlet.

[0070] S102, after delaying 100 ms, perform online monitoring on the driving motor.

[0071] S103, determine whether the driving motor is in an online state. If yes, execute step S104; if no, execute step S113.

[0072] S104, determine whether the number of power-on operations of the driving motor is 0. If yes, execute step S105; if no, execute step S106.

[0073] S105, perform position zero-finding on the electric air outlet, and take the current position of the driving motor after successful zero-finding as the starting position of the driving motor. Execute step S108.

[0074] S106, determine whether the pre-stored position is valid. If yes, execute step S107; if no, execute step S105.

[0075] S107, take the pre-stored position as the starting position of the driving motor.

[0076] S108, the number of power-on operations + 1.

[0077] S109, receive a target start instruction, and drive the driving motor based on the starting position to control the electric air outlet.

[0078] S110, determine whether a target stop instruction is received. If yes, execute step S111; if no, execute step S109.

[0079] S111, control the driving motor to stop running, and save the current position of the driving motor as the pre-stored position for the next power-on operation.

[0080] S112, control the electric air outlet to power off.

[0081] S113, issue a fault reminder.

[0082] For example, when the target flag information is 0, the online monitoring on the driving motor can include the following steps as shown in Figure 5

[0083] S201, obtain the initial flag information of the state flag bit of the driving motor.

[0084] ​S202, determine whether the initial flag information is all 0. If yes, execute step S203; if no, execute step S204.

[0085] S203, determine that the driving motor is in an online state.

[0086] S204, send first target information to the driving motor, so that the driving motor adjusts the state based on the first target information.

[0087] S205, obtain the current flag information of the state flag bit of the driving motor.

[0088] S206, determine whether the current flag information is all 0. If yes, execute step S203; if no, execute step S207.

[0089] S207, determine that the driving motor is not in an online state, and generate a fault signal.

[0090] In summary, according to the electric air outlet control method of the embodiment of the present application, in response to the power-on instruction, the driving motor is monitored online, and in the case that the driving motor is in an online state, the starting position of the driving motor is determined, and in the case that a target start instruction is received, the driving motor is driven based on the starting position to control the electric air outlet. Thus, when the power is turned on, the initialization control of the driving motor is realized through the online monitoring of the driving motor and the determination of the starting position of the driving motor, so as to ensure the control effect of the electric air outlet.

[0091] Corresponding to the above embodiment, the present application also provides an electric air outlet control device.

[0092] In an embodiment of the present application, the electric air outlet comprises a driving motor.

[0093] As shown in Figure 6 , the electric air outlet control device of the embodiment of the present application comprises a monitoring module 10, a determination module 20 and a control module 30.

[0094] The monitoring module 10 is used to monitor the driving motor online in response to the power-on instruction. The determination module 20 is used to determine the starting position of the driving motor in the case that the driving motor is in an online state. The control module 30 is used to drive the driving motor to operate based on the starting position of the driving motor in the case that a target start instruction is received, so as to control the electric air outlet.

[0095] According to one of the embodiments of the present application, the monitoring module 10 performs online monitoring on the driving motor, and specifically sends first target information to the driving motor, so that the driving motor adjusts its state based on the first target information; obtains current flag information of the state flag bit of the driving motor, and determines that the driving motor is in an online state when the current flag information is consistent with the target flag information.

[0096] According to one of the embodiments of the present application, before sending the first target information to the driving motor, the monitoring module 10 further obtains initial flag information of the state flag bit of the driving motor, and determines that the driving motor is in an online state when the initial flag information is consistent with the target flag information, and sends the first target information to the driving motor when the initial flag information is inconsistent with the target flag information.

[0097] According to one of the embodiments of the present application, the monitoring module 10 obtains the current flag information of the state flag bit of the driving motor, and specifically, in the case that feedback information sent by the driving motor is received within a preset time, determines the current flag information of the state flag bit of the driving motor based on the feedback information; in the case that the feedback information sent by the driving motor is not received within the preset time, determines that the driving motor loses communication.

[0098] According to one of the embodiments of the present application, the monitoring module 10 further determines that the driving motor has communication exception when the current flag information is inconsistent with the target flag information.

[0099] According to one of the embodiments of the present application, the determining module 20 determines the starting position of the driving motor, and specifically, in the case that the driving motor is powered on for the first time or in the case that the driving motor is powered on for the non-first time and the pre-stored position corresponding to the driving motor is invalid, controls the driving motor to perform position zero finding, and takes the current position of the driving motor after the position zero finding as the starting position of the driving motor; in the case that the driving motor is powered on for the non-first time and the pre-stored position of the driving motor is valid, takes the pre-stored position as the starting position of the driving motor.
