[0030] Embodiments of the present invention are described in detail below. The embodiments described with reference to the accompanying drawings are exemplary. Embodiments of the present invention are described in detail below.

[0031] In the related art, due to the structural setting of the step device, it is impossible to control the first and second steps of the step control device to unfold according to different passengers getting on the vehicle, and it is impossible to adjust the height of the step relative to the ground, which affects the convenience of passengers getting on and off the vehicle.

[0032] Therefore, the step control device of the vehicle using the embodiment of the present invention adjusts the usage status of the step according to the different step control signals triggered, controls the first-level step and the second-level step, that is, controls the first-level step to be unfolded, or controls the first-level step and the second-level step to be unfolded, so that when different users use the step device, the step can be controlled to unfold asynchronously and the height of the step relative to the ground can be adjusted, making it more convenient for special groups such as the elderly or children to get on and off the vehicle, and the control of the step device can be more intelligent.

[0033] The following describes a stepping device according to an embodiment of the present invention.

[0034] like Figure 1 As shown, the stepping device 200 includes: a first step 210, a second step 220, a first driving mechanism 230, a second driving mechanism 240 and a controller (not shown in the figure).

[0035] In one embodiment of the present invention, the first step 210 is adapted to be connected to the vehicle and configured to be opened or closed according to a step control signal.

[0036] It should be noted that in the vehicle coordinate system, the height direction of the vehicle is the Z-axis direction, the width direction is the Y-axis direction, and the length direction is the X-axis direction. In the width direction, the space inside the vehicle is the inner side of the vehicle width direction, and the space outside the vehicle is the outer side of the vehicle width direction. Figure 1 As shown, when the user gets on or off the vehicle, the first-level step 210 is unfolded relative to the outer side in the width direction of the vehicle body to facilitate the user to get on or off the vehicle. Before the vehicle moves, the first-level step 210 is closed relative to the outer side in the width direction of the vehicle body to prevent the first-level step 210 from being damaged by external forces.

[0037] In one embodiment of the present invention, Figure 1 As shown, the secondary step 220 can be movably connected below the primary step 210 to be opened or closed according to a step control signal.

[0038] Specifically, Figure 1 As shown, the secondary step 220 can be expanded and closed relative to the primary step 210. When in the closed position, the secondary step 210 is located below the primary step 210, that is, the secondary step 220 does not need to be used; when in the expanded position, the secondary step 220 rotates toward the outside of the primary step 210 to the lower side of the primary step 210, that is, in the width direction of the vehicle, the secondary step 220 rotates toward the side of the primary step 210 away from the vehicle body to the lower side of the primary step 210, making it convenient for children to get on and off the vehicle, so that the step device 200 satisfies the convenience of getting on and off the vehicle for both adults and children.

[0039] Moreover, the first step 210 and the second step 220 are independent of each other. In other words, when the second step 220 is not needed, the second step 220 is located below the first step 210 and is opened or closed with the first step 210. At this time, the step device 200 of the vehicle has only one step for the user to step on. When children get on and off the vehicle, not only the first step 210 but also the second step 220 needs to be opened. At this time, the step device 200 of the vehicle has two steps for the user to step on, so as to facilitate children to get on and off the vehicle.

[0040] In one embodiment of the present invention, Figure 1 As shown, the step device 200 of the vehicle further includes a first driving mechanism 230 , which is disposed below the primary step 210 and is drivingly connected to the secondary step 220 , and is used for driving the secondary step 220 to be opened or closed.

[0041] Specifically, Figure 1As shown, the first driving mechanism 230 is installed below the first step 210 and is drivingly connected to the second step 220, so that the first driving mechanism 230 can drive the second step 220 to rotate and swing toward the outside of the first step 210 to achieve an expanded state, or drive the second step 220 to rotate and swing toward the inside of the first step 210 to achieve a closed state.

[0042] In one embodiment of the present invention, Figure 1 As shown, the second driving mechanism 240 is drivingly connected to the first step 210 and is used to drive the second step 220 to expand or close.

[0043] Specifically, Figure 1 As shown, the second driving device 240 is suitable for being installed on the vehicle body, and the second driving device 240 is drivingly connected to the first step 210 so that the second driving device 240 drives the first step 210 to expand toward the outside of the vehicle body or close toward the inside of the vehicle body.

[0044] In one embodiment of the present invention, Figure 1 As shown, the controller is used to control the expansion of the first step 210 in response to the control signal of the first step 210, or to control the expansion of the first step 210 and the second step 220 in response to the control signal of the second step 220.

[0045] Specifically, Figure 1 As shown, the controller controls the deployment of the first-stage step 210 according to the step control signal, or controls the deployment of the first-stage step 210 and the second-stage step 220. When the controller receives the deployment signal of the first-stage step 210, the first-stage step 210 is controlled to be deployed toward the outside of the vehicle body; when the controller receives the deployment signal of the first-stage step 210 and the second-stage step 220, the first-stage step 210 is controlled to be deployed toward the outside of the vehicle body, and the second-stage step 220 is controlled to be deployed.

[0046] Based on the structure of the stepping device of the above-mentioned vehicle, the signal interaction method of the stepping control method of the vehicle according to the embodiment of the present invention is described below by way of example.

[0047] In an embodiment, Figure 2 FIG. 1 is a schematic diagram of information interaction of a step control device for a vehicle according to an embodiment of the present invention. The power mode, step mode and step state are set, and the step is automatically opened / closed according to different users using the step device, so as to realize the control of the step device.

[0048] The following uses the adult mode and the child mode as examples to illustrate the step control method of the vehicle of the present invention. Figure 3The figure shows a hardware interaction diagram of a stepping control device in an adult mode according to an embodiment of the present invention. The power mode is turned on by the central controller, and the user is identified by the camera, and the body control module is set to transmit signals with the controller. When the signal received by the controller is a first-level stepping control signal, the controller will control the first driving mechanism 230 to expand / close and prohibit the second driving mechanism 240 from starting; if the stepping motion is blocked, the controller controls the head-up display system to display the blocked stepping motion.

[0049] like Figure 4 The figure is a hardware interaction diagram of a stepping control device according to another embodiment of the present invention. The power mode is turned on by the central controller, the user is identified by the camera, the body control module is set, and the signal is transmitted with the controller. When the signal received by the controller is a secondary stepping control signal, the controller controls the first driving mechanism 230 and the second driving mechanism 240 to expand / close; if the stepping motion is blocked, the head-up display system is controlled to display the blocked stepping motion.

[0050] Based on the above step control device, the following Figure 5 The step control method of a vehicle according to an embodiment of the present invention is described as follows: Figure 5 As shown, the step control method of a vehicle in the embodiment of the present invention at least includes steps S1 and S2.

[0051] Step S1: responding to a primary step control signal or a secondary step control signal.

[0052] The step control signal is a control signal sent by the vehicle body control module and is used to control the primary step and the secondary step of the step device.

[0053] In a specific embodiment, different users are identified by a camera, and based on the user's characteristics, it is determined whether the user currently getting on or off the vehicle is an adult, a child, or an elderly person. After the current required user is determined, the corresponding step control signal is determined based on the current required user. For example, if the current user is determined to be an adult, the body control module will issue a first-level step control signal, and the controller receives and responds to the first-level step control signal, and when receiving the first-level step control signal, it responds to the first-level step control signal to enable adults to get on and off the vehicle normally.

[0054] The remote control key can also be used to select functions. The corresponding step control mode is triggered by the remote control key. The body control module receives the corresponding first-level step control signal in this mode, so that the controller can control the first-level step accordingly according to the first-level step control signal.

[0055] Step S2: correspondingly controlling the first-level step to unfold, or controlling the first-level step and the second-level step to unfold.

[0056] In an embodiment, in response to a primary step control signal, the expansion / closing of the primary step is controlled according to the primary step control signal, or in response to a secondary step control signal, the expansion and closing of the primary step and / or the secondary step is controlled according to the secondary step control signal. For example, after receiving a secondary step expansion signal, the controller can control the expansion of the primary step and the secondary step, so that when different users use the stepping device, the height of the step relative to the ground can be adjusted by controlling the steps to expand asynchronously, making it more convenient for special groups such as the elderly or children to get on and off the vehicle, and the control of the stepping device is more intelligent.

[0057] Therefore, the above-mentioned vehicle step control method adjusts the use status of the step according to the different step control signals triggered, controls the first-level step and the second-level step, that is, controls the first-level step to be unfolded, or controls the first-level step and the second-level step to be unfolded, so that when different users use the step device, the step can be controlled to unfold asynchronously and the height of the step relative to the ground can be adjusted, making it more convenient for special groups such as the elderly or children to get on and off the vehicle, and the control of the step device is more intelligent.

[0058] In one embodiment of the present invention, controlling the expansion of the first step and the second step includes: controlling the expansion of the first step, and when the expansion time of the first step reaches a first preset interval time, controlling the second step to expand until the expansion time of the second step reaches a first preset time, wherein the first preset time is less than a preset time threshold.

[0059] In an embodiment, when controlling the first step and the second step to unfold, the first step is controlled to unfold, and after the first step is unfolded, for example, the unfolding time of the first step is t1, and the first preset interval time is, for example, t2, that is, the delay time after the first step is unfolded, so that the first step and the second step are unfolded at different times and are in the set position. Since the second step is closer to the ground, after the second step is unfolded, for example, the height of the second step from the ground is at a comfortable height for users, such as children. Therefore, by controlling the second step and the first step to unfold at different times, it is more convenient for users to get on or off the vehicle.

[0060] For example, when the user is a child and the child is in the state of getting on / off the vehicle, the first-level step and the second-level step can be controlled to unfold according to the step control signal, the time t1 for a single unfolding of the first-level step is less than 2S, and then the second-level step is unfolded after a delay of t2, and the time for a single unfolding of the second-level step is t3, and t3 is less than 2S, wherein the delay time t2 is less than 2S. Thus, the first-level step and the second-level step can be unfolded, and by controlling the steps to unfold asynchronously and adjusting the height of the steps relative to the ground, it is more convenient for special groups such as the elderly or children to get on and off the vehicle, and the control of the step device is more intelligent.

[0061] In one embodiment of the present invention, controlling the expansion of the first step and the second step includes: controlling the expansion of the second step, and when the expansion time of the second step reaches a second preset interval time, controlling the first step to expand until the expansion time of the first step reaches the second preset time, wherein the second preset time is less than a preset time threshold.

[0062] In an embodiment, the first step and the second step are controlled to be unfolded. Specifically, when it is identified that the user is a child and the child is in the state of getting on / off the vehicle, the second step can be controlled to be unfolded according to the step control signal, and when the unfolding time of the second step reaches the second preset interval time, the first step can be controlled to be unfolded until the unfolding time of the first step reaches the second preset time. For example, the time for a single unfolding of the second step is t3, the second preset interval time is t4, and the time for a single unfolding of the first step is t1, that is, the second preset time for the first step to be unfolded is controlled to be t5.

[0063] Specifically, when the child is in the state of getting on / off the vehicle, when the vehicle's step control is performed, the second step is controlled to be unfolded, and when the single unfolding time t3 of the second step reaches the second preset interval time t4, the first step is controlled to be unfolded, and the first step is unfolded to the second preset time t5, wherein the second preset time t5 is less than the preset time threshold, for example, the preset time threshold is 2S, which can be understood as the single unfolding time t3 of the second step is within the second preset interval time t4, that is, the delay time after the single unfolding of the second step is less than 2S, and after t3 reaches t4, the first step is unfolded, and the single time t1 of the first step is also less than 2S. By controlling the unfolding of the first and second steps, the height of the step relative to the ground can be adjusted, making it more convenient for special groups such as the elderly or children to get on and off the vehicle, and the control of the stepping device is more intelligent.

[0064] In one embodiment of the present invention, controlling the expansion of the first step and the second step includes: controlling the expansion of the first step and the second step synchronously until the expansion time of the first step and the second step reaches a third preset time, wherein the third preset time is less than a preset time threshold.

[0065] In an embodiment, when controlling the first-stage pedal and the second-stage pedal to unfold, the first-stage pedal and the second-stage pedal can be controlled to unfold synchronously, wherein the preset time threshold can be a set time, and when the first-stage pedal and the second-stage pedal are unfolded to a set height, the first-stage pedal and the second-stage pedal can be controlled to unfold according to a third preset time, and the third preset time is less than the preset time threshold. By controlling the pedals to unfold synchronously, the height of the step relative to the ground can be adjusted according to the user, making it more convenient for special groups such as the elderly or children to get on and off the vehicle, and the control of the stepping device is more intelligent.

[0066] In one embodiment of the present invention, controlling the first step to unfold includes: controlling the first step to unfold, and controlling the second step to close, until the unfolding time of the first step reaches a fourth preset time, wherein the fourth preset time is less than a preset time threshold.

[0067] In the embodiment, the first step is controlled to be unfolded according to the step control signal, that is, the first step is controlled to be unfolded for a preset time, and the second step is controlled to be closed, wherein the fourth preset time is less than the preset time threshold. It can be understood that when the controller receives the first step unfolding signal, the first step can be controlled to be unfolded, and its single unfolding time is the fourth preset time t6, and the second step is controlled to be in a closed state, that is, in the first step control mode, the first step is unfolded according to the fourth preset time t6, and the second step is in a closed state, wherein the fourth preset time t6 is less than the preset time threshold, for example, if the preset time threshold is 2S, then t6 is less than 2S.

[0068] In one embodiment of the present invention, before responding to the first-level step control signal or responding to the second-level step control signal, it also includes: acquiring image information of the identification area; determining a personnel feature signal based on the image information; and issuing a first-level step control signal or issuing a second-level step control signal based on the personnel feature signal.

[0069] In an embodiment, image information of the identification area is obtained by a camera, and based on the image information, a person feature signal is obtained, for example, based on the facial features of the person, to determine whether the person is an adult, a child, or an elderly person. Based on the person feature signal, a first-level step control signal or a second-level step control signal is controlled to be sent, and different step control strategies are implemented through the person features to adjust the height of the step relative to the ground according to the user, so that special groups such as the elderly or children can get on and off the vehicle more conveniently, and the control of the step device is more intelligent.

[0070] In one embodiment of the present invention, the process of controlling the deployment of the first step and / or the second step also includes: determining whether the first step touches an obstacle; if so, triggering the anti-pinch protection strategy of the first step; determining whether the second step touches an obstacle, and if so, triggering the anti-pinch protection strategy of the second step.

[0071] In an embodiment, during the deployment of the first-level step and / or the second-level step, it can be determined whether the first-level step and / or the second-level step touches an obstacle. If an obstacle is touched during this process, the anti-pinch protection strategy of the first-level step and / or the second-level step will be triggered. The obstacles include, for example, people, foreign objects, etc. By triggering the anti-pinch protection strategy of the first-level step and / or the second-level step, the user can be prevented from being pinched during the process of getting on and off the vehicle, thereby improving the safety of the user getting on and off the vehicle.

[0072] In one embodiment of the present invention, responding to a step control signal includes: responding to a primary step control signal when a primary step control signal is received; and responding to a secondary step control signal when a secondary step control signal is received.

[0073] In an embodiment, the step control signal may include a primary step control signal and a secondary step control signal. If the controller receives a primary step control signal, it responds to the primary step control signal; if the control signal received by the controller is a secondary step control signal, it responds to the secondary step control signal. Specifically, when performing the step control of the vehicle, according to the user information recognized by the face recognition camera, if the user is an adult, the primary step control mode will be turned on, that is, the primary step will be controlled to be expanded or closed; if the user is a child, the secondary step control mode will be turned on, that is, the secondary step will be controlled to be expanded or closed.

[0074] Furthermore, the first-level step control mode can be understood as a single-step mode, and the second-level step control mode can be understood as a double-step mode. When the user is an adult and is in the state of getting on the vehicle, the first-level step is controlled according to the first-level step control signal received by the controller, so that the current first-level step is in an expanded state, and the single expansion time of the first-level step is controlled to be t, for example, 2S. After the single expansion time of the first-level step reaches 2S, the first-level step is controlled to be closed to facilitate the user to get on the vehicle; when the user is a child and is in the state of getting on the vehicle, the second-level step is controlled according to the second-level step control signal received by the controller, so that the current second-level step is in a closed state, and when the single expansion time of the second-level step is reached, the second-level step is controlled to be closed. Thus, by controlling the first-level step and / or the second-level step according to the control signal received by the controller, the height of the step relative to the ground can be adjusted, making it more convenient for special groups such as the elderly or children to get on and off the vehicle, and the control of the stepping device is more intelligent.

[0075] In one embodiment of the present invention, the vehicle step control method further includes: controlling the first-stage step and the second-stage step to be closed in response to a step closing control signal.

[0076] In the embodiment, when the controller receives a step closing signal, that is, the electric step of the vehicle receives a closing signal of the first step and the second step, the first step and the second step are controlled to close. For example, the preset interval time after the first step and the second step are both 2S, when the user gets on and off the vehicle through the first step and the second step within 2S, the vehicle will send a step closing signal to control the first step and the second step to close.

[0077] In one embodiment of the present invention, controlling the first step and the second step to close includes: controlling the first step and the second step to close simultaneously, or controlling the first step and the second step to close in sequence according to a preset interval time.

[0078] In an embodiment, according to the user's getting on and off the vehicle, the first step and the second step can be controlled to be closed at the same time, or the first step and the second step can be controlled to be closed in sequence according to a preset interval time.

[0079] For example, when the user identified by the camera is a child and is in the state of getting on / off the vehicle, the first and second steps are controlled to unfold according to the user's getting on / off the vehicle, that is, two steps for getting off the vehicle are provided for the user to step on. When the user gets off the vehicle by using the first and second steps, the first and second steps will be controlled according to the received step control signal, and the first and second steps will be controlled to be closed in sequence according to the preset interval time. By controlling the asynchronous unfolding of the steps, the height of the steps relative to the ground can be adjusted, making it more convenient for special groups such as the elderly or children to get on and off the vehicle, and the control of the step device is more intelligent. In addition, if the user is in the state of getting off the vehicle after the door is opened, but the user does not get off the vehicle within the preset time, and the vehicle continues to drive after the door is closed, at this time, the first and second steps will be controlled to be closed at the same time.

[0080] In summary, the step control method of a vehicle according to the embodiment of the present invention can control the asynchronous expansion of the steps and adjust the height of the steps relative to the ground when different users use the step device, making it more convenient for special groups such as the elderly or children to get on and off the vehicle, and making the control of the step device more intelligent.

[0081] Next, a vehicle according to an embodiment of the present invention will be described.
