[0055] The accompanying drawings illustrate specific embodiments of this application, which will be described in more detail below. These drawings and descriptions are not intended to limit the scope of the concept in any way, but rather to illustrate the concept of this application to those skilled in the art through reference to particular embodiments. Detailed Implementation

[0056] Exemplary embodiments will now be described in detail, examples of which are illustrated in the accompanying drawings. When the following description relates to the drawings, unless otherwise indicated, the same numbers in different drawings denote the same or similar elements. The embodiments described in the following exemplary embodiments do not represent all embodiments consistent with this application. Rather, they are merely examples of apparatuses and methods consistent with some aspects of this application as detailed in the appended claims.

[0057] First, let me explain the terms used in this application:

[0058] Openable roof components: These are components on the roof of a vehicle that can be opened and closed. When openable roof components are in the open position, they provide occupants with a wide field of vision and good ventilation. Common openable roof components include convertible systems or sunroofs.

[0059] With the rapid development of the automotive industry, in order to meet the rapidly evolving needs of user experience, openable roof components are widely used in vehicles and are gradually becoming popular in the market due to their unique open driving experience and ventilation advantages.

[0060] However, while these vehicles offer convenience, they also pose significant safety hazards. For example, in the event of a collision, rollover, or other sudden dangerous situation, if the convertible top is open or the sunroof is not fully closed, debris such as gravel and obstructions from the external environment can easily enter the vehicle through the opening or gap, directly impacting the occupants and causing secondary injuries. Furthermore, during a collision or rollover, occupants may be thrown outwards due to inertia; an open convertible top or sunroof will lose its effective restraint, significantly increasing the risk of occupants being ejected from the vehicle and thus drastically increasing the probability of injury or death.

[0061] In some embodiments, the openable roof part of the vehicle is generally opened or closed in response to active control by a user. In the related art, there is no control scheme for the openable roof part in an emergency or emergency situation, and the safety of the vehicle is poor.

[0062] The control method for the openable roof part of the vehicle provided in the present application, when the openable roof part of the vehicle is in an open state, if the current state of the vehicle is detected as a dangerous state according to a signal of the vehicle, in order to ensure the personal safety of the driver and passengers in the vehicle, prevent foreign objects from entering the vehicle or the vehicle occupants from leaving the vehicle, the actuator of the openable roof part of the vehicle is controlled by a control signal to drive the openable roof part to close. Through the above technical scheme, the safety of the vehicle occupants can be effectively protected when the vehicle is in a dangerous situation, and the safety of the vehicle is improved.

[0063] The technical scheme of the present application and how the technical scheme of the present application solves the above technical problems will be described in detail in the following specific embodiments. The following specific embodiments can be combined with each other, and the same or similar concepts or processes can not be described in detail in some embodiments. The embodiments of the present application will be described below with reference to the accompanying drawings.

[0064] Figure 1 The flowchart of the control method for the openable roof part of the vehicle provided in the present application is shown in Figure 1 The method comprises:

[0065] Step 101. When the openable roof part of the vehicle is in an open state, at least one signal in the vehicle is obtained.

[0066] Among them, the at least one signal includes an airbag control signal and / or a sensor signal.

[0067] For example, the openable roof part of the vehicle is provided with a position detection sensor. For example, a Hall sensor is installed at both ends of the guide rail of the openable roof part. Specifically, when the openable roof part runs to one end of the guide rail, it is recorded as a fully closed state; when it runs to the other end of the guide rail, it is recorded as a fully open state.

[0068] Optionally, the openable roof part can also stop between the two ends of the guide rail, which is recorded as a partially open state. It can be understood that whether it is a fully open state or a partially open state, it belongs to an open state.

[0069] Therefore, the Hall sensor at one end of the guide rail detects that the openable roof part is not in a fully closed state, i.e. it can be determined that the openable roof part of the vehicle is in an open state.

[0070] In the case that the openable roof part of the vehicle is determined to be in an open state, at least one signal of the vehicle is acquired. The at least one signal can include an airbag control signal and / or a sensor signal.

[0071] It can be appreciated that in one possible case, the airbag control signal of the vehicle is acquired. In another possible case, the sensor signal of the vehicle is acquired. In yet another possible case, the airbag control signal and the sensor signal of the vehicle are acquired.

[0072] Step 102. Determine the vehicle state according to the at least one signal.

[0073] For example, the vehicle state is determined according to the at least one signal acquired above. In combination with the explanation in the foregoing steps, in one possible case, the vehicle state is determined according to the airbag control signal of the vehicle.

[0074] Specifically, if the airbag control signal of the vehicle indicates that the airbag of the vehicle has been deployed, the vehicle state of the vehicle can be determined to be a dangerous state. Otherwise, the vehicle state of the vehicle is determined to be a non-dangerous state.

[0075] In another possible case, the vehicle state is determined according to the sensor signal of the vehicle.

[0076] Specifically, if the sensor signal of the vehicle indicates that the vehicle is currently subjected to a collision, the vehicle state of the vehicle can be determined to be a dangerous state. Otherwise, the vehicle state of the vehicle is determined to be a non-dangerous state.

[0077] Further, the sensor can be a collision sensor deployed outside the vehicle, which can determine whether the vehicle is subjected to a collision by detecting the instantaneous acceleration outside the vehicle body.

[0078] In yet another possible case, the vehicle state is determined according to the airbag control signal and the sensor signal of the vehicle.

[0079] Specifically, if the airbag control signal of the vehicle indicates that the airbag of the vehicle has been deployed, or the sensor signal of the vehicle indicates that the vehicle is currently subjected to a collision, the vehicle state of the vehicle can be determined to be a dangerous state. It can be appreciated that in order to prevent false triggering of a single signal, the vehicle state of the vehicle is determined to be a dangerous state only when both signals meet the conditions at the same time.

[0080] Optionally, on the basis of the foregoing example, the at least one signal of the vehicle can further include an image signal. The image signal is acquired by a camera deployed outside the vehicle.

[0081] Further, in combination with the image signal, if the image signal represents that a potential dangerous object appears in front of the vehicle, the vehicle state of the vehicle is determined as a dangerous state. Wherein, the image signal can be input to a pre-trained image recognition model for detection and recognition, so as to determine whether a potential dangerous object appears in front of the vehicle in the image signal.

[0082] On this basis, in another possible case, if one or more of the following conditions are met, the vehicle state of the vehicle is determined as a dangerous state: if the airbag control signal of the vehicle represents that the airbag of the vehicle has been ejected; the sensor signal of the vehicle indicates that the vehicle is currently subjected to a collision; the image signal represents that a potential dangerous object appears in front of the vehicle.

[0083] Step 103. If it is determined that the vehicle state is a dangerous state, a first control signal is generated; and the first control signal is sent to the actuator of the openable roof part to drive the actuator to drive the openable roof part to close.

[0084] For example, if it is determined that the vehicle state is a dangerous state, a first control signal is generated. Wherein, the first control signal is used to control the actuator of the openable roof part to drive the openable roof part to close. That is, to switch from an open state to a closed state.

[0085] Specifically, the actuator can include a motor and a transmission mechanism. The first control signal is sent to the motor in the actuator, the motor drives the transmission mechanism, and then the transmission mechanism drives the openable roof part to close.

[0086] Optionally, the priority of the above-mentioned first control instruction is higher than that of the daily control instruction. The actuator simultaneously receives the first control instruction and the daily control instruction, and the first control instruction indicated by the first control instruction is preferentially executed to control the closing action of the openable roof part, so as to ensure the response priority in the accident scene.

[0087] The control method of the openable roof part of the vehicle provided by the embodiment of the present application acquires at least one signal in the vehicle when the openable roof part of the vehicle is in an open state. The current vehicle state of the vehicle is determined through the at least one signal. If the current vehicle state is a dangerous state, a control signal is generated. And the openable roof part is driven to close through the driving mechanism of the openable roof part based on the control signal. The openable roof part is automatically controlled and closed when the vehicle is in a dangerous state. The safety of the people in the vehicle is effectively protected, and the safety of the vehicle is improved.

[0088] In addition, the at least one signal can more accurately identify a high-risk scene and avoid false triggering.

[0089] On the basis of the foregoing embodiment, the at least one signal in the vehicle can include an airbag control signal, and a sensor signal. On this basis, a vehicle state is determined according to the at least one signal, including:

[0090] If it is determined that the airbag control signal represents that the airbag has been ejected, or it is determined that the sensor signal meets a preset condition, the vehicle state is determined to be a dangerous state.

[0091] Illustratively, the airbag control signal is used to control the ejection of the airbag when the vehicle is in a dangerous state. By the ejected airbag, the driver and the passenger inside the vehicle can be prevented from being bumped due to the forward inertia.

[0092] Therefore, in combination with the dangerous situation in the driving scene, when the airbag control signal indicates that the airbag is ejected, it can be judged that the vehicle is in a dangerous state.

[0093] Illustratively, the sensor signal can indicate the driving state of the vehicle. For example, the sensor can include a collision sensor disposed outside the vehicle. When the sensor signal collected by the collision sensor meets the preset condition, it can be determined that the vehicle is in a dangerous state.

[0094] In combination with the above two exemplary explanations, it can be understood that the above two cases meet a case, that is, the vehicle state is determined to be a dangerous state.

[0095] The vehicle state can be determined from the driving level of the vehicle through the sensor signal, and the vehicle state can be determined from the hardware execution level of the vehicle through the airbag control signal. Based on the signals of two dimensions, the vehicle state of the vehicle can be more comprehensively determined.

[0096] Further, the sensor signal is collected by at least one sensor configured on the vehicle, and the at least one sensor includes a collision sensor and / or a rollover sensor. The collision sensor is used to collect the instantaneous acceleration of the vehicle, and the rollover sensor is used to collect the inclination angle and angular velocity of the vehicle.

[0097] Illustratively, one or more sensors can be configured on the vehicle. One data collected by the sensor corresponds to one sensor signal.

[0098] For example, a collision sensor is configured on the vehicle, and the collision sensor collects the instantaneous acceleration of the vehicle.

[0099] For another example, a rollover sensor is configured on the vehicle, and the rollover sensor collects the inclination angle and angular velocity of the vehicle.

[0100] For example, the vehicle is provided with a collision sensor and a roll sensor. Correspondingly, the at least one sensor signal includes: the instantaneous acceleration of the vehicle, the inclination angle of the vehicle and the angular velocity of the vehicle.

[0101] Optionally, the collision sensor can be a piezoelectric collision sensor installed at the key positions of the front, rear and side frames of the vehicle, which can detect the change of the instantaneous acceleration of the vehicle. The roll sensor can be a dual-axis inclination sensor installed at the middle of the vehicle body, which can monitor the inclination angle and angular velocity of the vehicle body around the longitudinal axis in real time.

[0102] On this basis, whether the data carried by the sensor signal meets the preset condition can be determined by setting the relevant threshold. Therefore, the determination that the sensor signal meets the preset condition in the above process includes at least one of the following:

[0103] determining that the instantaneous acceleration is greater than or equal to a first threshold value, and the duration that the instantaneous acceleration is greater than or equal to the first threshold value is greater than a preset time;

[0104] determining that the inclination angle is greater than or equal to a second threshold value;

[0105] determining that the angular velocity is greater than or equal to a third threshold value.

[0106] In one example, when the instantaneous acceleration is greater than or equal to the first threshold value and the duration is greater than the preset time, it can be determined that the sensor signal meets the preset condition. Specifically, when the value of the instantaneous acceleration is greater than or equal to 150 m / s², and the duration that is greater than or equal to the threshold value is ≥ 50 ms, it is determined that the sensor signal meets the preset condition.

[0107] In one example, when the inclination angle is greater than or equal to the second threshold value, it can be determined that the sensor signal meets the preset condition. Specifically, when the inclination angle is greater than or equal to 45°, it is determined that the sensor signal meets the preset condition.

[0108] In one example, when the angular velocity is greater than or equal to the third threshold value, it can be determined that the sensor signal meets the preset condition. Specifically, when the angular velocity is greater than or equal to 50° / s, it is determined that the sensor signal meets the preset condition.

[0109] It should be noted that the above three examples can be implemented alone or in combination. In the combined implementation process, any two examples can be combined, or all three examples can be combined.

[0110] By setting different thresholds, different data in the sensor signal can be judged respectively. When any kind of data exceeds the threshold, it is determined that the vehicle state of the vehicle is a dangerous state. Moreover, by combining the duration with the instantaneous acceleration, the real high-risk scene can be more accurately identified. For example, when the vehicle suddenly brakes and the acceleration exceeds the threshold for a short time, the duration does not reach the threshold to avoid false triggering, and in the real collision or rolling scene, the response is fast, which significantly improves the timeliness and accuracy of the emergency shutdown action.

[0111] Further, the instantaneous acceleration includes lateral acceleration and longitudinal acceleration.

[0112] The determination that the instantaneous acceleration is greater than or equal to the first threshold value includes:

[0113] The determination that the lateral acceleration is greater than or equal to the first threshold value or the determination that the longitudinal acceleration is greater than or equal to the first threshold value.

[0114] For example, the instantaneous acceleration includes lateral acceleration and longitudinal acceleration. The longitudinal direction refers to the forward direction or the backward direction of the vehicle during straight driving, and the lateral direction refers to the vertical direction of the longitudinal direction, i.e., the left translation direction or the right translation direction of the vehicle during straight driving. It can be understood that the longitudinal acceleration is the instantaneous acceleration of the vehicle in the above forward direction or backward direction, and the lateral acceleration is the instantaneous acceleration of the vehicle in the above left translation direction or right translation direction.

[0115] On this basis, the value of the lateral acceleration is greater than or equal to 150 m / s², or the value of the longitudinal acceleration is greater than or equal to 150 m / s², which can be determined as the instantaneous acceleration greater than or equal to the first threshold value.

[0116] It should be noted that, whether the lateral acceleration or the longitudinal acceleration exceeds the first threshold value, the duration exceeds the preset time. However, since either the value of the lateral acceleration or the value of the longitudinal acceleration exceeding the first threshold value is counted as the instantaneous acceleration exceeding the first threshold value. Therefore, in one example, the duration of the lateral acceleration exceeding the first threshold value is less than the preset time, but before the lateral acceleration is less than the first threshold value, the longitudinal acceleration exceeds the first threshold value, and the duration needs to be counted. If the sum of the duration of the lateral acceleration exceeding the first threshold value and the duration of the longitudinal acceleration exceeding the first threshold value is greater than or equal to the preset time, it can also be determined that the sensor signal meets the preset condition.

[0117] In the above embodiments, by combining the airbag control signal and the sensor signal, it can be determined whether the vehicle state of the vehicle is a dangerous state, and the vehicle state can be more accurately determined. By setting the threshold values of different data in the sensor signal, the dangerous situation can be more comprehensively identified. Moreover, both the lateral and longitudinal directions of the instantaneous acceleration are determined, and the dangerous state triggered by the front collision of the vehicle and the side collision of the vehicle is included. In summary, the comprehensiveness and accuracy of the identification of the dangerous state of the vehicle can be improved, the false triggering rate can be reduced, and the emergency closing action for the openable roof part can be more reliably triggered.

[0118] On the basis of any of the foregoing embodiments, in a case where the vehicle state of the vehicle is a dangerous state, the openable roof part is controlled to switch from an open state to a closed state. The object outside the vehicle is prevented from entering the vehicle, the person inside the vehicle is prevented from being injured, and the driver and the passenger inside the vehicle are prevented from leaving the vehicle from the openable roof part in the open state.

[0119] In combination with the actual driving scene, in a real collision scenario, the openable roof part has been switched to the closed state. At this time, if the consciousness of the person inside the vehicle is clear, the person needs to escape from the vehicle, and the openable roof part needs to be further opened.

[0120] In an example, after the first control signal is sent to the actuator of the openable roof part to drive the actuator to drive the openable roof part to close, the method further comprises:

[0121] If it is determined that the vehicle state is a non-dangerous state, a second control signal is generated, and the second control signal is sent to the actuator of the openable roof part to drive the actuator to drive the openable roof part to open.

[0122] For example, in combination with the above example, the vehicle is configured with a collision sensor and a roll sensor, which can collect the instantaneous acceleration and angular velocity of the vehicle. If the instantaneous acceleration and angular velocity are less than the preset safety threshold, it can be determined that the vehicle stops after the collision and the vehicle posture is stable. At this time, it can be determined that the vehicle state is a non-dangerous state.

[0123] Further, a second control signal is generated. The second control signal is used to control the actuator of the openable roof to drive the openable roof part to open. That is, to switch from the closed state to the open state.

[0124] Optionally, other sensors can also be configured inside the vehicle. For example, a smoke sensor. If the smoke sensor detects that the concentration of toxic gas inside the vehicle exceeds the preset safety threshold, it is determined that the current vehicle has a fire risk, and a second control signal can also be generated to control the openable roof part to open to allow the person inside the vehicle to escape.

[0125] Optionally, a deformation sensor can also be configured in the roof area of the vehicle. If the deformation sensor detects that the openable roof component of the vehicle has a serious deformation, direct control of opening is not possible at this time, and a third control signal is generated. The third control signal is used to control the unlocking of the vehicle door. In combination with the actual scene, if there is a serious deformation in the roof area of the vehicle after the collision or rollover, it is not suitable to directly open the openable roof component at this time, but in order to escape for the people inside the vehicle, the vehicle door can be controlled to be unlocked, so that the people inside the vehicle can escape from the vehicle door.

[0126] Optionally, the priority of the second control instruction is higher than that of the daily control instruction. In addition, it should be pointed out that since the first control instruction and the second control instruction do not appear at the same time, the priority of the first control instruction and the second control instruction can be the same, but both are higher than the priority of the daily control instruction.

[0127] In the above example, in the case where the vehicle returns to a non-dangerous state, the openable roof component of the vehicle can be automatically opened. In order to facilitate the escape of the people inside the vehicle, the safety of the vehicle is improved. The user does not need to manually open it again, and the intelligence of the control of the vehicle is improved.

[0128] In combination with the foregoing example, it can be seen that the openable roof component is a convertible system of the vehicle, or a sunroof on the roof of the vehicle.

[0129] Illustratively, the openable roof component is a convertible system of the vehicle. The vehicle with the convertible system is a convertible. The convertible system refers to a vehicle system that realizes the opening and closing of the roof through a mechanical structure.

[0130] Further, the convertible system can also include a soft-top convertible and a hard-top convertible. The soft-top convertible includes a folding canvas and a metal frame. The opening and closing of the soft-top convertible are realized by driving the metal frame to drive the folding canvas through a hydraulic mechanism or a motor. The hard-top convertible includes a segmented metal roof and a sliding rail. The opening and closing of the hard-top convertible is realized by driving the segmented metal roof to move in the sliding rail through a motor.

[0131] Illustratively, the openable roof component is a sunroof on the roof of the vehicle. The sunroof can be a sliding sunroof or an outward tilting sunroof. The sliding sunroof can include a single layer of glass, a guide rail and a motor. The opening and closing of the sunroof are realized by driving the single layer of glass to move on the sliding rail through the motor. The outward tilting sunroof can include a single layer of glass, a hinge and a motor. The opening and closing of the sunroof is realized by driving the single layer of glass to tilt upward under the constraint of the hinge through the motor.

[0132] In the above example, through the actuator and the separately established power module, vehicles of different types with different types of openable roof components can be compatible, further improving the reliability.

[0133] The control method of the openable roof part of the vehicle provided in the embodiments of the present application comprises the following steps: obtaining at least one signal in the vehicle when the openable roof part of the vehicle is in an open state; determining a current vehicle state of the vehicle according to the at least one signal; generating a control signal if the current vehicle state is a dangerous state; and driving the openable roof part to close by a driving mechanism of the openable roof part based on the control signal. Thus, the openable roof part can be automatically controlled and closed when the vehicle is in a dangerous state, thereby effectively protecting the safety of the people in the vehicle and improving the safety of the vehicle.

[0134] In addition, the high-risk scene can be more accurately identified by the at least one signal, and false triggering can be avoided. Specifically, the vehicle state is determined to be a dangerous state or not in combination with the airbag control signal and the sensor signal, so that the vehicle state can be more accurately determined. By setting the threshold of different data in the sensor signal, the dangerous scene can be more comprehensively identified. Moreover, both the lateral and longitudinal instantaneous accelerations are determined, so that the dangerous state triggered by the front collision of the vehicle and the side collision of the vehicle is included. The identification comprehensiveness and determination accuracy of the dangerous state of the vehicle are improved, and the emergency closing action of the openable roof part can be more reliably triggered.

[0135] Figure 2 The control device of the openable roof part of the vehicle provided in the present application is shown in a structural schematic diagram as shown in Figure 2 The control device 20 of the openable roof part of the vehicle provided in the embodiments comprises:

[0136] The obtaining module 201 is configured to obtain at least one signal in the vehicle when the openable roof part of the vehicle is in an open state, wherein the at least one signal comprises an airbag control signal and / or a sensor signal.

[0137] The processing module 202 is configured to determine a vehicle state according to the at least one signal.

[0138] The processing module 202 is further configured to generate a first control signal if the vehicle state is determined to be a dangerous state, and send the first control signal to an execution mechanism of the openable roof part, so that the execution mechanism drives the openable roof part to close.

[0139] In a possible implementation, the processing module 202 is configured to determine the vehicle state according to the at least one signal.

[0140] If it is determined that the airbag control signal represents that the airbag has been ejected, or it is determined that the sensor signal meets a preset condition, the vehicle state is determined to be a dangerous state.

[0141] In a possible implementation, the sensor signal is collected by at least one sensor configured on the vehicle, and the at least one sensor includes: a collision sensor and / or a rollover sensor; wherein the collision sensor is configured to collect an instantaneous acceleration of the vehicle, and the rollover sensor is configured to collect an inclination angle and an angular velocity of the vehicle.

[0148] The processing module 202 is configured to determine that the lateral acceleration is greater than or equal to the first threshold value, or determine that the longitudinal acceleration is greater than or equal to the first threshold value.

[0149] In a possible implementation, after the first control signal is sent to the actuator of the openable roof part to drive the actuator to drive the openable roof part to close, the processing module 202 is further configured to:

[0150] If it is determined that the vehicle state is a non-dangerous state, a second control signal is generated, and the second control signal is sent to the actuator of the openable roof part to drive the actuator to drive the openable roof part to open.

[0151] In a possible implementation, the openable roof part is a convertible system of the vehicle, or a sunroof on the roof of the vehicle.

[0152] The control device of the openable roof part of the vehicle provided in this embodiment can perform the method provided in the method embodiments, and has similar implementation principles and technical effects, which will not be described here in detail.

[0153] Figure 3 A structural schematic diagram of the control device provided in this embodiment is shown in FIG. 3. Figure 3 As shown in FIG. 3, the control device 30 provided in this embodiment includes at least one processor 301 and a memory 302. Optionally, the control device 30 further includes a communication component 303. The processor 301, the memory 302 and the communication component 303 are connected through a bus 304.

[0154] In a specific implementation process, the at least one processor 301 executes the computer execution instructions stored in the memory 302, so that the at least one processor 301 executes the above-mentioned method.

[0155] The specific implementation process of the processor 301 can refer to the method embodiments described above, which have similar implementation principles and technical effects, and will not be described here in detail.

[0156] In the above embodiments, it should be understood that the processor can be a central processing unit (English: Central Processing Unit, for short: CPU), and can also be other general-purpose processors, digital signal processors (English: Digital Signal Processor, for short: DSP), application specific integrated circuits (English: Application Specific Integrated Circuit, for short: ASIC), etc. The general-purpose processor can be a microprocessor, or the processor can also be any conventional processor, etc. The steps of the method disclosed in combination with the application can be directly embodied as hardware processor execution, or executed by hardware and software modules in the processor.

[0157] The memory can contain a random access memory (Random Access Memory, RAM), and can also include a non-volatile memory (Non-volatile Memory, NVM), for example, at least one disk memory.

[0158] The bus can be an industry standard architecture (Industry Standard Architecture, ISA) bus, a peripheral component interconnect (Peripheral Component, PCI) bus, or an extended industry standard architecture (Extended Industry Standard Architecture, EISA) bus, etc. The bus can be divided into an address bus, a data bus, a control bus, etc. For the convenience of representation, the bus in the drawings of the present application does not limit only one bus or one type of bus.

[0159] The present application also provides a vehicle. Figure 4 The structure of the vehicle provided in the present application is shown in Figure 1 As shown in Figure 4 , the vehicle 40 includes a control device 30, an actuator 401, and an openable roof part 402.

[0160] The control device 30 is in communication connection with the actuator 401, and the actuator 401 is in mechanical connection with the openable roof part 402.

[0161] The control device 30 is configured to control the actuator 401 to drive the openable roof component 402 to open or close.

[0162] For example, the control device can be a microcontroller unit (MCU) with high computing speed (clock speed not less than 100 MHz) and anti-interference ability, which is suitable for complex electromagnetic environment of vehicles.

[0163] The actuator can be distinguished according to different types of openable roof components. For a soft-top convertible in a convertible system, a double-motor synchronous drive mechanism is adopted, equipped with a reduction gear set (transmission ratio not less than 1:50) to improve driving torque. For a hard-top convertible in a convertible system, a hydraulic drive system is adopted, equipped with a high-pressure oil pump (working pressure ≥ 10 MPa) to ensure fast folding and closing of the hard top.

[0164] For a sunroof, a direct-current brushless motor is adopted, matched with a ball screw transmission structure, and the maximum speed of the motor is ≥ 3000 rpm to ensure that the sunroof completes the action from “complete opening” to “complete closing” within 1 second.

[0165] Specifically, the control device can adjust the motor speed or hydraulic pump flow through pulse width modulation (PWM) technology to make the convertible / sunroof run at the maximum speed.

[0166] Optionally, according to the Hall sensor deployed at the openable roof component, if it is determined that the openable roof component is in a completely closed state, the actuator is immediately controlled to stop action to avoid mechanical damage caused by overdrive.

[0167] Figure 5 Structure of the vehicle provided in the present application Figure 2 As shown in Figure 5 one possible implementation, the vehicle 40 is further configured with at least one sensor 403, and further includes an airbag controller 404. Each sensor 403 and airbag controller 404 is connected to the control device 30.

[0168] For example, on the basis of the foregoing example, the MCU is further configured with a signal conditioning circuit to receive analog signals collected by each sensor, convert them into digital signals, and filter out high-frequency noise interference (such as noise generated by sensor vibration). The control device can receive at least one signal from each sensor and airbag controller to determine the state of the vehicle.

[0169] Further, the vehicle can further include a power guarantee module, comprising: a backup power supply and a power switching circuit. The backup power supply adopts a super capacitor (with a capacity not less than 50F) or a backup lead-acid battery, which is connected in parallel with the main power supply of the vehicle. A voltage monitoring chip monitors the voltage of the main power supply of the vehicle in real time (the normal range is 12V-14V), and when the main power supply voltage is suddenly reduced (such as lower than 9V) or disconnected due to a collision / tumbling, the power switching circuit triggers the action of a relay to switch the power supply source to the backup power supply, so as to ensure that the central control module and the execution driving module can still maintain stable power supply for at least 3 seconds after the accident, which is sufficient to complete the closing action of the convertible roof / sunroof. The stable power supply for at least 3 seconds is sufficient to control the openable roof part of the vehicle to be closed. This is because under the control of the first control signal, the execution mechanism can be driven to realize the complete closing of the openable roof part at a faster speed.
