[0052] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this application. All other embodiments obtained by those skilled in the art based on the embodiments of this application without creative effort are within the scope of protection of this application.

[0053] Electric running boards are door sills installed below the vehicle doors that can be extended or adjusted in height, commonly found in SUVs and SUVs. An electric running board typically includes a motor, an adjustment mechanism connected to the motor's output shaft, and a pedal connected to the adjustment mechanism. When the electric running board is needed, the motor drives the adjustment mechanism, changing the position or posture of the pedal, thus switching between extended / retractable states or adjusting its height.

[0054] Off-road vehicles and SUVs are often used for travel or adventure, where users typically carry a lot of equipment or luggage, requiring them to place some items on roof racks. In related technologies, an electric step extends outward at a fixed height to elevate the user when they need to retrieve items from the roof. However, due to significant height differences among people, some shorter users, even with the fixed-height electric step, still cannot easily retrieve items from the roof.

[0055] Based on this, to address the problem of how to help shorter users retrieve items from the roof of a vehicle, this application provides a method, system, storage medium, and vehicle for adjusting the height of an electric pedal. When a user needs to retrieve or place an item from the roof, the system collects the height of the user's body at the highest point when their hand is raised, thus obtaining the user's height. Subsequently, based on the user's height and the vehicle's height, a target height for the electric pedal is determined, allowing the electric pedal height to be adjusted to suit different user heights. The electric pedal height in this application can adapt to different user heights when users need to retrieve or place items from the roof, enabling shorter users to easily complete the action of retrieving or placing items from the roof, thereby achieving the effect of helping users of different heights retrieve items from the roof. The specific method is as follows:

[0056] The first aspect of this application provides an embodiment, such as... Figure 1 The diagram illustrates a method for adjusting the height of an electric pedal. The method is implemented in a vehicle-mounted controller and includes the following main steps:

[0057] Step S101: In response to the triggering of the target mode, the electric pedal is deployed.

[0058] The target mode can be the roof mode, or the mode the vehicle needs to enter when the user needs to retrieve items from the top of the vehicle. When the user needs to retrieve items from the top of the vehicle, they can enter the target mode via the mode selection button located on the dashboard or center console. After the vehicle enters the target mode, the vehicle controller sends a corresponding control signal to the motor of the electric pedal (here and below, "electric pedal" should specifically refer to the "pedal" in the electric pedal device), so that the motor, upon receiving the control signal, drives the adjustment mechanism to unfold the electric pedal.

[0059] In this mode, the electric pedals will not extend or retract as the doors are closed or opened; that is, the electric pedals will remain extended until the vehicle exits the target mode.

[0060] Step S102: When the user is on the electric pedal, the vehicle height is acquired, and the height of the highest point of the user's body when in a preset posture is collected to obtain the user height. The preset posture is the user's hand raised away from the lower limbs, and the user height represents the vertical distance between the highest point of the body and the ground.

[0061] The vehicle's height is the vertical distance between the top of the vehicle and the ground. In vehicles with a fixed suspension height, the vehicle height can be obtained through a preset height in the onboard controller. In vehicles with a variable suspension height, the vehicle height can be determined based on the suspension height.

[0062] The preset posture refers to the user's hand position, which is raised away from the lower limbs; simply put, it's the posture when the user's hand is raised upwards. Since the highest point of the user's body when their hand is raised is at the raised hand, the height of the highest point of the user's body in the preset posture is the same as the height of their raised hand, and also the highest point the user can reach. Therefore, based on common sense, when determining the target height of an electric pedal, the height of the user's highest point in the preset posture should be used as the benchmark.

[0063] The height of a user's highest point in a preset posture can be captured in various ways. In one optional implementation, it can be captured using a camera mounted on the exterior of the vehicle. When capturing the user's height in the preset posture using the camera, the camera's capture action can be automatically triggered based on the user's posture. For example, image recognition can be performed on the image captured by the camera to determine whether the user is currently in the preset posture. If the image recognition indicates that the user is currently in the preset posture, height capture is automatically triggered to obtain the user's height.

[0064] In an alternative implementation, determining whether a user is on the electric pedal can be done using pressure sensors installed on the electric pedal. Two pressure sensors, corresponding to the user's left and right feet respectively, are installed at specific locations on the electric pedal, such as between the front and rear doors. When the user is located at the position of the pressure sensor, the pressure sensor senses pressure and sends a pressure signal to the vehicle controller. Upon receiving the pressure signal, the vehicle controller can then determine that the user is currently on the electric pedal.

[0065] Step S103: Based on the user's height and the vehicle body height, determine the target height of the electric pedal. The target height represents the vertical distance between the electric pedal and the ground.

[0066] After obtaining the vehicle's height and the user's height, the target height of the electric pedal is determined based on these measurements. In one optional implementation, the target height can be obtained by looking up a preset correspondence table between the user's height, vehicle height, and target height.

[0067] Step S104: Adjust the height of the electric pedal to the target height.

[0068] After determining the target height of the electric pedal, the vehicle controller determines the target position of the motor output shaft corresponding to the target height, and controls the motor output shaft to rotate to the target position, so that the adjustment mechanism drives the electric pedal to move to the target height.

[0069] This application collects the height of the user's body at the highest point when their hand is raised, when the user needs to retrieve or place items on the roof of the vehicle, thus obtaining the user's height. Subsequently, based on the user's height and the vehicle's height, a target height for the electric step is determined, allowing the electric step height to be adjusted to suit different user heights. The electric step height in this application can adapt to different user heights when users need to retrieve or place items from the roof, enabling even shorter users to easily complete the action of retrieving or placing items from the roof, thereby achieving the effect of helping users of different heights to access items from the roof.

[0070] In another embodiment of this application, in addition to including the steps in the embodiments described above, it further includes:

[0071] Optionally, such as Figure 2 The diagram illustrates a height acquisition method. Step S102, which involves acquiring the height of the user's highest body point when the user is in a preset posture, includes:

[0072] Step S1021: In response to the first acquisition command sent by the first component, determine whether a second acquisition command sent by the second component has been received within a preset time period. Here, the first component and the second component are different components configured in the vehicle.

[0073] To prevent accidental height adjustments when the user is on the electric pedal, two trigger conditions can be set for the height acquisition action of the vehicle controller. Specifically, the vehicle controller is connected to both the first and second components. When the vehicle controller receives the first acquisition command sent by the first component, it starts timing under the trigger of the first acquisition command, and during the timing process, it determines whether the second acquisition command has been received within a preset time period.

[0074] Step S1022: If a second acquisition command is received from the second component within the preset time period, the height of the highest point of the user's body when the user is in a preset posture is acquired.

[0075] If a second acquisition command is received from the second component within a preset time period, it indicates that the user does indeed intend to adjust the height of the electric pedal, and the height of the user in the preset posture will be collected. If a second acquisition command is not received from the second component within a preset time period, it indicates that the first acquisition command may have been falsely triggered, and height collection should not be performed to prevent accidental safety accidents from occurring during the user's electric pedal height adjustment process.

[0076] In one optional implementation, the first component can be a smart key or a Bluetooth key. The user triggers the key to send a first acquisition command to the vehicle controller by pressing and holding the lock button on the smart key or Bluetooth key for a certain duration. Simultaneously, the second component can be a pressure sensor mounted on the electric pedal, and the second acquisition command can be the pressure signal acquired by the pressure sensor. For example, when the user raises their leg, the pressure sensor switches from a pressurized state to a depressurized state and sends a pressure change signal to the vehicle controller; when the user lowers their leg, the pressure sensor switches from a depressurized state back to a pressurized state and sends another pressure change signal to the vehicle controller. The second acquisition command is then the two consecutive pressure change signals sent by the pressure sensor to the vehicle controller. Upon receiving the second acquisition command, the vehicle controller begins to acquire the height of the user's highest point in a preset posture.

[0077] Optionally, such as Figure 3 The diagram illustrates a method for determining a user's height using a target terminal. Step S102 involves collecting the height of the user's highest point when in a preset posture to obtain the user's height. This includes:

[0078] Step S1023: In response to the triggering of the altitude calibration command sent by the target terminal, obtain the field strength information corresponding to the signal sent by the target terminal.

[0079] To improve the accuracy of the height data collected by the vehicle controller, the height of the user's highest point in a preset posture can be collected through height calibration. Specifically, the vehicle controller connects to a target terminal, which can be a Bluetooth key, or a mobile phone, tablet, wearable device, or personal computer connected to the vehicle controller. The user's height is determined by the target location of the target terminal.

[0080] Taking a Bluetooth key as an example, to enable the user's altitude measurement function, the vehicle should also have a Bluetooth antenna installed below the electric pedal for receiving Bluetooth signals. When the user triggers the Bluetooth key to send an altitude calibration command to the vehicle controller, the vehicle controller, triggered by the altitude calibration command, controls the Bluetooth antenna to send a signal to locate the Bluetooth key. After receiving this signal, the Bluetooth key replies to the Bluetooth antenna with a corresponding signal carrying the Bluetooth key's field strength information, and finally transmits the field strength information to the vehicle controller.

[0081] Step S1024: Based on the field strength information, determine the target location of the target terminal.

[0082] Since the field strength information contains information about the strength of the signal field, and the strength of the signal field decreases as the distance between the transmitting and receiving ends increases, the target location of the target terminal can be determined by the strength of the signal field in the field strength information.

[0083] Step S1025: Determine the user height based on the target location and the preset location.

[0084] The preset location should be a location with a fixed or measurable distance from the ground. Similar to step S1023, taking a Bluetooth key as the target terminal as an example, when the vehicle controller receives the field strength information emitted by the Bluetooth key via the Bluetooth antenna, the vehicle controller can determine the target location of the Bluetooth key based on the strength information of the Bluetooth signal field carried in the field strength information. Therefore, when the user holds the Bluetooth key and raises their hand upwards, the target location of the Bluetooth key is the location of the user's hand, which is the highest point of the user's body.

[0085] Furthermore, the preset location can be the location of the Bluetooth antenna or the ground. If the preset location is the location of the Bluetooth antenna, then the user's height should be the distance between the Bluetooth antenna and the target terminal, plus the distance between the Bluetooth antenna and the ground.

[0086] Optionally, such as Figure 4 The diagram illustrates a method for determining a target height. Step S103, which involves determining the target height of the electric pedal based on the user's height and the vehicle body height, includes:

[0087] Step S1031: Determine the height difference between the user's height and the vehicle body height.

[0088] refer to Figure 5 The diagram illustrates a scenario for determining a target height. The user height is the vertical distance between the highest point of the user's body and the ground when the user raises their hand away from their lower limbs, and the vehicle height is the vertical distance between the top of the vehicle and the ground. Therefore, the height difference between the user height and the vehicle height is the distance between the user's raised hand and the vehicle height.

[0089] Step S1032: Determine the target height based on the height difference and the height adjustment coefficient of the electric pedal.

[0090] After determining the distance between the user's raised hand and the vehicle's height, and considering the impact of ergonomics on user behavior, to reduce the difficulty for users to reach items, the target height of the electric pedal can be determined by combining the height difference between the user's height and the vehicle's height with a height adjustment coefficient.

[0091] In one alternative implementation, the height adjustment factor can be a fixed value. For example, based on ergonomics, it is most convenient for the user to pick up items when their hand height, i.e., the user's height, is higher than the vehicle height by a preset length. Therefore, this preset length can be used as the height adjustment factor to adjust the target height of the electric pedal.

[0092] Optionally, such as Figure 6 The diagram illustrates a method for adjusting the height of an electric pedal. Step S104, adjusting the height of the electric pedal to the target height, includes:

[0093] Step S1041: Based on the target height and the initial height of the electric pedal, determine the height adjustment direction and height adjustment value of the electric pedal.

[0094] The target height is the height at which the electric pedal allows the user to easily retrieve or place items from the roof by pressing it. The initial height is the height of the electric pedal when the vehicle enters the target mode. In one optional implementation, the height adjustment direction and value of the electric pedal can be determined by the difference between the target height and the initial height. If the target height is higher than the initial height, the difference is positive, indicating that the electric pedal should be adjusted upwards, and the height adjustment value is this positive number. If the target height is lower than the initial height, the difference is negative, indicating that the electric pedal should be adjusted downwards, and the height adjustment value is the absolute value of this negative number.

[0095] Step S1042: Control the electric pedal to move the height adjustment value in the height adjustment direction.

[0096] After determining the height adjustment direction and height adjustment value of the electric pedal, the vehicle controller sends a rotation command corresponding to the height adjustment direction to the motor of the electric pedal. The rotation command includes the target direction of the motor output shaft rotation and the target number of rotations of the output shaft, so as to control the motor output shaft to rotate in the target direction and the adjustment device to move the electric pedal to the target height after rotating the target number of rotations.

[0097] Optionally, such as Figure 7 The diagram illustrates a method for obtaining a target height through a mapping relationship. The method includes:

[0098] Step S201: In response to the triggering of the target mode, the electric pedal is deployed.

[0099] The specific implementation of step S201 is the same as that of step S101, as described above.

[0100] Step S202: When the user is on the electric pedal, the vehicle height is acquired, and the height of the highest point of the user's body when in a preset posture is collected to obtain the user height. The preset posture is the user's hand raised away from the lower limbs, and the user height represents the vertical distance between the highest point of the body and the ground.

[0101] The specific implementation of step S202 is the same as that of step S102, as described above.

[0102] Step S203: Based on the user's height and the vehicle body height, determine the target height of the electric pedal. The target height represents the vertical distance between the electric pedal and the ground.

[0103] The specific implementation method of step S203 is the same as that of step S103, and refer to the description of step S103 above.

[0104] Step S204: Obtain the user's identity identifier.

[0105] Identification can be biometric features such as a user's facial image, voice, or fingerprint, or information such as the key code of the Bluetooth key used by the user.

[0106] Step S205: Establish a mapping relationship between the identity identifier and the target height, and store the mapping relationship.

[0107] After determining the target height of the electric pedal based on the user's height, the user's identification is mapped to the target height to establish a mapping relationship between the identification and the target height, and this mapping relationship is stored in the storage module in the vehicle controller.

[0108] Step S206: When the target mode is triggered again, the target height corresponding to the user is obtained from the mapping relationship based on the user's identity identifier.

[0109] When the user triggers the vehicle to enter the target mode again, the target height corresponding to the identity identifier can be determined directly through the stored mapping relationship, thereby reducing the number of calculations by the vehicle controller and speeding up the adjustment speed of the electric pedal height.

[0110] For example, a user's identity is identified by the key code of the Bluetooth key they use. After determining the target altitude, the key code of the Bluetooth key is bound to the target altitude, thus establishing a mapping relationship between the key code of the Bluetooth key and the target altitude, and this mapping relationship is stored. When the user re-enters the target mode, they can determine the target altitude corresponding to the key code by sending the key code to the vehicle controller via the Bluetooth key.

[0111] Optionally, such as Figure 8 The diagram illustrates a method for adjusting the height of an electric pedal based on load. The method includes:

[0112] Step S301: In response to the triggering of the target mode, the electric pedal is deployed.

[0113] The specific implementation of step S301 is the same as that of step S101, as described above.

[0114] Step S302: When the user is on the electric pedal, the vehicle height is obtained, and the height of the highest point of the user's body when in a preset posture is collected to obtain the user height; wherein, the preset posture is the posture in which the user's hands are raised away from the lower limbs, and the user height is used to represent the vertical distance between the highest point of the body and the ground.

[0115] The specific implementation of step S302 is the same as that of step S102, as described above.

[0116] Step S303: Determine the target height of the electric pedal based on the user's height and the vehicle body height; wherein the target height represents the vertical distance between the electric pedal and the ground.

[0117] The specific implementation method of step S303 is the same as that of step S103, and refer to the description of step S103 above.

[0118] Step S304: Adjust the height of the electric pedal to the target height.

[0119] The specific implementation of step S304 is the same as that of step S104, as described above.

[0120] Step S305: Obtain the variation range of the load borne by the electric pedal.

[0121] The load borne by the electric pedal can be collected by a pressure sensor installed on the electric pedal. The variation range of the load borne by the electric pedal refers to the difference between the maximum load and the minimum load borne by the electric pedal.

[0122] Considering that the method described in this application applies to scenarios where users retrieve items from the roof of a vehicle, the load on the electric pedal will change after the user removes the item from the roof or places it on the roof. Therefore, the magnitude of the change in load on the electric pedal can be used to determine whether the user has completed the action of retrieving the item.

[0123] Step S306: When the change amplitude is greater than a preset threshold, adjust the electric pedal from the target height to the initial height.

[0124] When the load variation on the electric pedal exceeds a preset threshold, it indicates that the user has completed the action of retrieving the item. At this point, to accommodate the user's movement when stepping off the pedal and to avoid potential safety hazards due to the electric pedal being too high, the electric pedal should be adjusted from the target height to its initial height.

[0125] A third aspect of this application provides an embodiment, such as... Figure 9 A flowchart illustrating a method for adjusting the height of an electric pedal is shown. The method is applied to an onboard controller, which is connected to a first component, a second component, and a target terminal. The method includes:

[0126] When the user is on the electric pedal, the vehicle's height is acquired. Simultaneously, in response to a first acquisition command sent by a first component, it is determined whether a second acquisition command sent by a second component has been received within a preset time period; wherein the first and second components are different components configured in the vehicle. If the second acquisition command sent by the second component is received within the preset time period, in response to the triggering of a height calibration command sent by the target terminal, the field strength information corresponding to the signal emitted by the target terminal is acquired. Based on the field strength information, the target location of the target terminal is determined; based on the target location and a preset location, the user's height is determined; wherein the preset posture is the user's hand raised away from the lower limbs, and the user height is used to characterize the vertical distance between the highest point of the body and the ground.

[0127] Determine the height difference between the user's height and the vehicle's height; based on this height difference and the height adjustment coefficient of the electric pedal, determine the target height. The target height represents the vertical distance between the electric pedal and the ground.

[0128] After determining the target height, based on the target height and the initial height of the electric pedal, the height adjustment direction and height adjustment value of the electric pedal are determined; the electric pedal is then controlled to move in the height adjustment direction by the height adjustment value.

[0129] The system acquires the variation range of the load borne by the electric pedal; when the variation range exceeds a preset threshold, the electric pedal is adjusted from the target height to the initial height.

[0130] In addition, after determining the target height, the user's identity can be obtained; a mapping relationship between the identity and the target height can be established and stored; when the target mode is triggered again, the target height corresponding to the user can be obtained from the mapping relationship based on the user's identity.

[0131] Furthermore, the method described in this embodiment will be illustrated using a real-world scenario as an example, with reference to... Figure 10 A schematic diagram of a vehicle structure for adjusting the height of an electric pedal is shown, and Figure 11 This is a schematic diagram showing an initial height, a reference height, and a vehicle height.

[0132] refer to Figure 10 The vehicle includes an onboard controller, a smart key module, a multimedia host, and an electric pedal module, all connected to the onboard controller. The smart key module includes a low-frequency antenna connected to the onboard controller and a smart key connected to the low-frequency antenna. The electric pedal module includes a pedal controller connected to the onboard controller, and pressure sensors and pedal actuators connected to the pedal controller. Two pressure sensors are located under the user's left and right feet, respectively.

[0133] The user triggers the vehicle to enter the target mode via the mode selection button on the multimedia host. When the vehicle enters the target mode, the electric pedal is at its initial height H1. At this time, the user, carrying a valid smart key, stands with their left and right feet respectively above the pressure sensors. Under pressure, the pressure sensors send a pressure signal to the vehicle controller, allowing the vehicle controller to determine that the user is currently on the electric pedal.

[0134] The user stands on the electric footrest, holds the smart key, raises their hand away from their lower limbs, and simultaneously presses and holds the lock button T1 on the smart key for one second. This triggers the smart key to send a height calibration command and a first data acquisition command to the vehicle controller. Subsequently, within a preset time, the user lifts and lowers either foot, causing the pressure sensor to switch from a pressurized state to a depressurized state, thus triggering the footrest controller to send a second data acquisition command to the vehicle controller.

[0135] Upon receiving the second acquisition command, the vehicle controller drives the low-frequency antenna installed under the electric pedal to transmit a 125kHz LF (Low Frequency) signal to locate the smart key. After receiving the 125kHz LF signal, the smart key replies with a 433.92MHz RF (Radio Frequency) signal carrying RSSI (Received Signal Strength Indication) field strength information. After receiving the 433.92MHz RF signal, the vehicle controller calculates the distance H2 between the smart key and the low-frequency antenna based on the RSSI field strength information, and further determines the user height as H1 + H2. Simultaneously, the vehicle height H3 is obtained from the data pre-written into the vehicle controller, thus determining the height difference H4 between the user height and the vehicle height as H1 + H2 - H3. Since it is most convenient for the user to reach items from the top of the vehicle when their hand height exceeds the vehicle height by a length X when standing on the electric pedal, the height adjustment factor is determined to be X based on ergonomics. Therefore, based on the height difference H4 and the height adjustment coefficient X, the target height M of the electric pedal can be determined as X-H4+H1.

[0136] Furthermore, since the height of the electric pedal when the vehicle enters the target mode is H1, the height adjustment value Y of the electric pedal is M-H1, i.e., X-H4. After calculating the height adjustment value of the electric pedal, the vehicle controller notifies the pedal controller via the CAN (Controller Area Network) line, and the pedal controller drives the pedal actuator to raise or lower the electric pedal.

[0137] At the same time, the vehicle controller binds the target height M with the smart key ID (IdentityDocument) that participated in the electric pedal height calibration and stores it in the storage module of the multimedia host. Then, the next time the target mode is entered, the target height bound to the smart key is automatically retrieved from the storage module of the multimedia host through the smart key ID, so that the electric pedal automatically rises to the pre-calibrated position.
