To further clarify the above and other features and advantages of the present application, a further description of the present application is provided below with reference to the appended drawings. It should be understood that the specific embodiments described herein are for illustrative purposes only and are not limiting, as to those skilled in the art.
In the following description, numerous specific details are set forth in order to provide a thorough understanding of the present application. However, it will be apparent to one skilled in the art that the specific details need not be employed to practice the present application. In other instances, well-known steps or operations have not been described in detail in order to avoid obscuring the present application.
In view of the foregoing, the hidden door handle in the prior art has a single mode and cannot cope with complex application scenes, and the application provides an anti-freezing control method and device for the hidden door handle, which aim at solving the technical problems.
Referring to fig. 1, fig. 1 is a flowchart of an anti-freezing control method for a hidden door handle according to an embodiment of the present invention, including:
step S10, acquiring the current state of the vehicle and the accepted control signal;
step S20, determining an operation mode of the hidden door handle according to the current state and the control signal, wherein the operation mode comprises a normal mode, an ice breaking mode and an ice melting mode;
step S30, controlling the hidden door handle to execute the determined operation mode.
Under the normal mode, the hidden door handle pops up normally under the mechanical force of opening the door of normal work numerical value, under the mode of breaking ice, the hidden door handle pops up with the mechanical force of opening the door of predetermineeing, under the mode of melting ice, the heating wire of control hidden door handle department heats hidden door handle.
It is understood that the current state of the vehicle and the accepted control signal are acquired in step S10, and the current state of the vehicle may include an open-close state of a door, a vehicle motion state, a vehicle ambient temperature; the vehicle motion state comprises a static state, a running state, a parking state and a safe mode state. The control signal includes: an unlocking signal and an ice melting control signal of the automobile.
In step S20, the operation mode of the hidden door handle is determined according to the current state and the control signal, that is, the proper operation mode is selected according to the mapping relationship between the current state and the control signal and the operation mode, so that the hidden door handle has higher adaptability.
In summary, the hidden door handle in the general inventive concept has a plurality of different operation modes, can automatically adapt to different situations, and can intelligently judge the proper operation mode by analyzing the current state of the vehicle and the received control signals compared with the single operation mode in the prior art, so that the most proper processing mode can be automatically selected according to different situations, the intelligent and automatic degree of a door handle system is improved, the efficiency of a shutter is improved, the service life of the hidden door handle is prolonged, the user can use the door more efficiently, and the overall user experience is improved.
The present solution is illustrated by a specific example below:
referring to fig. 2, fig. 2 is a flowchart illustrating a step S2 in the anti-freezing control method according to an embodiment of the present invention.
In step S2, determining the operation mode of the hidden door handle according to the current state and the control signal includes:
step S21, after receiving an unlocking signal, determining whether the hidden door handle is normally opened;
and S22, controlling the operation mode of the hidden door handle to be switched to the ice breaking mode under the condition that the hidden door handle is not normally opened.
In the embodiment of the invention, the unlocking signal can be an unlocking signal output by a user through remote control, or can be an unlocking signal sent out by some specific running logics of the vehicle, such as an unlocking signal sent out by safety measures taken by the vehicle to deal with emergency after collision.
In one possible way of determining whether the hidden door handle is normally opened, the opening of the door handle is detected by a sensor, and when the hidden door handle does not reach a preset opening threshold in the opened state, it is determined that the hidden door handle is not normally opened.
In the control logic, as soon as an unlocking signal is received, whether the hidden door handle is normally opened or not is judged, and when the hidden door handle is not normally opened, the operation mode of the hidden door handle is preferentially controlled to be switched to the ice breaking mode.
It will be appreciated that with this control logic, the unlock signal is directly used to control the mode of operation of the door handle without additional operations or intervention. Therefore, a more convenient vehicle door unlocking mode can be provided, the operation steps of a user are reduced, the control logic has the advantages of providing convenience, increasing safety and better protecting the hidden door handle of the vehicle, ensuring that the vehicle door can be smoothly opened when the hidden door handle cannot work normally, simultaneously preventing the user from violently disassembling, and reducing the potential damage risk to the vehicle and the door handle.
In step S2, determining the operation mode of the hidden door handle according to the current state and the control signal includes:
step S23, under the condition that ice breaking is not successful, controlling the operation mode of the hidden door handle to be switched to an ice melting mode;
and step S24, under the condition that the ice breaking is successful, controlling the operation mode of the hidden door handle to be switched to the normal mode.
It will be appreciated that in the control logic updated on the basis of step S22, the following two steps are added: and under the condition that the ice is not broken successfully, controlling the operation mode of the hidden door handle to be switched to the ice melting mode. Namely, when the hidden door handle cannot break ice, the operation mode of the hidden door handle is switched to the ice melting mode. And under the condition that the ice breaking is successful, controlling the operation mode of the hidden door handle to be switched to the normal mode. When the hidden door handle is successfully opened after ice breaking, the system automatically switches the door handle operation mode back to the normal mode. The benefit of these two steps is that the adaptability of the hidden door handle to severe weather or icing conditions is increased. When the door handle cannot be opened through the ice breaking process, an additional solution can be provided through the ice melting mode, so that the door can be opened. Once the door handle is successfully thawed and opened, the system automatically switches back to normal mode to ensure normal use. That is, when it is detected that the hidden door handle cannot be opened normally, the ice breaking mode is adopted to break ice first, so as to accelerate the door handle to be unfolded quickly, and when the hidden door handle cannot be operated in the ice breaking mode, the hidden door handle is switched to the ice melting mode, so that the hidden door handle can be ensured to maintain normal operation.
In a further aspect of the embodiment of the present invention, determining an operation mode of the hidden door handle according to the current state and the control signal includes:
step S21', determining that the ice melting control signal is received, and controlling the operation mode of the hidden door handle to be switched to the ice melting mode.
It can be understood that the user can input the ice melting control signal by himself, the hidden door handle is controlled to enter the ice melting heating mode by operating the central control, and after the central control sends out the ice melting instruction, the hidden door handle receives the instruction and starts to enter the ice melting mode, so that the heating state of the hidden door handle is maintained, and ice is prevented.
Referring to fig. 3, fig. 3 is a flowchart illustrating a step S3 in the anti-freezing control method according to an embodiment of the present invention.
In the embodiment of the invention, the anti-freezing control method further comprises the following steps:
and S31, under the ice breaking mode, applying door opening mechanical force to the hidden door handle, and judging whether the ice breaking is successful or not.
It can be understood that the door opening mechanical force applied to the hidden door handle in the ice breaking mode is larger than the door opening mechanical force of a normal working value, and the purpose of the design is to ensure that the door which is iced can be smoothly opened, provide stronger force to break ice, and improve the success rate of opening the door.
In an optional manner of the present application, for step S31, in the ice breaking mode, applying a door opening mechanical force to the hidden door handle, and determining whether the ice breaking is successful includes:
step S311, applying a preset first value of door opening mechanical force to the hidden door handle;
step S312, according to the order of judging whether the ice breaking is successful, controlling the door opening mechanical force to gradually increase from the first value, and judging whether the ice breaking is successful each time the door opening mechanical force is applied.
It can be appreciated that in one strategy provided in the present application, an initial door opening mechanical force value, i.e., a first value, is initially applied in the ice breaking mode to provide enough force to break ice, and after each application of the door opening mechanical force, it is determined whether the door handle can reach a preset opening threshold, i.e., whether each determination as described above is successful in breaking ice, if not, the control system gradually increases the door opening mechanical force, and if it is determined that the ice breaking is successful, it means that the door handle applies enough force to open the door that is iced, then enters the normal mode, i.e., continues to enter the door opening operation. If the determination is unsuccessful, the system may continue to increase the door opening mechanical force and repeat the determination until successful.
It should be noted that in the process of gradually increasing the door opening mechanical force, an upper limit value is set to ensure that excessive force is not applied to prevent damage to the door or other vehicle body components.
The mode of gradually increasing the door opening mechanical force from the first value can be adopted to gradually increase the duty ratio of the driving motor (namely, the driving device for controlling the hidden door handle to open the door), so that the torque or the rotating speed output by the driving motor is gradually increased, and further, larger force is gradually applied to open the door. Different degrees of icing can be handled. Lighter icing may require less force to break, while more severe icing requires more force. The mechanical force of the door opening is gradually increased, so that the door opening device can be ensured to adapt to different conditions, and the success rate of icebreaking is improved. Avoiding damage to the components caused by the application of excessive force. The design can protect the hidden door handle while guaranteeing effective ice breaking so as to prolong the service life of the hidden door handle.
If the mechanical force reaches the upper limit value, the ice is not broken successfully, the breaking of the ice fails, and the ice melting mode is entered.
Further, in another aspect provided by the embodiment of the present invention, in step S31, in the ice breaking mode, applying a door opening mechanical force to the hidden door handle, and determining whether the ice breaking is successful includes:
step S311', after a preset number of times of door opening mechanical force with a preset second value is applied to the hidden door handle, judging whether the ice breaking is successful.
According to the scheme, the system continuously applies a second numerical door opening mechanical force to try to open, the preset times of ice breaking operation are continuously carried out, and whether ice is successfully broken is judged after the door is continuously opened by keeping the second numerical door opening mechanical force unchanged. For example, when the door opening mechanical force of the second value is continuously adopted three times, whether the ice breaking is successful or not is judged, namely, whether the last opening reaches the opening threshold value or not. If the condition is met, if the condition is not met after three attempts, controlling the hidden door handle to enter the ice melting mode.
In the embodiment of the present invention, the step S30 of controlling the hidden door handle to execute the determined operation mode includes:
step S32, in the ice melting mode, controlling the heating wire to heat the hidden door handle, and judging whether ice melting is successful or not;
step S33, under the condition that ice melting fails, controlling the heating wire to continuously heat the hidden door handle for a preset first time period, and then judging whether ice melting is successful again;
and step S34, under the condition that ice melting is successful, controlling the operation mode of the hidden door handle to be switched to a normal mode.
It will be appreciated that in the ice melting mode, the heating wires are controlled to heat the hidden door handle and the system applies heat to the hidden door handle by activating the heating wires to expedite the melting of ice. Then, whether ice melting is successful or not is determined according to specific judging conditions, and under the condition that the ice melting fails, the system can continuously control the heating wire to continuously heat the hidden door handle, and the hidden door handle is heated according to a preset first time. This step is intended to try to further melt the ice to solve the problem of ice-melting failure, in which case the system will switch the hidden door handle mode of operation to normal mode. This means that the ice has melted completely and the hidden door handle can resume normal operation, allowing the user to smoothly open and close the door.
In an optional mode of the embodiment of the invention, whether the ice melting is successful or not is judged in the ice melting mode, the door opening mechanical force with normal working values can be adopted to try to open the door every preset period, and if the hidden door handle can reach the opening threshold, the ice melting is proved to be successful at the moment, and the operation mode of the hidden door handle is controlled to be switched to the normal mode. If the ice melting fails, the heating wire is controlled to continuously heat the hidden door handle for a preset first time period, and whether the ice melting is successful is judged again.
Further, in step S33, in the case of failure of melting ice, controlling the heating wire to continuously heat the hidden door handle for a preset first period of time, and then judging whether the melting ice is successful again includes:
step S331, along with judging whether the ice melting is successful, the first time period is controlled to be continuously increased.
It will be appreciated that the first time period is not set to a fixed value and that by varying the sequence, the first time period is continually lengthened, thereby achieving a faster ice melting efficiency.
Similarly, in the ice melting mode, the logic control needs to set a time upper limit value, and if the time upper limit value is reached, the ice melting mode is jumped out to prompt abnormality.
It will be appreciated that, first, after the failure of melting ice, a preset first period of time, i.e., an initial heating period of time, is set to attempt melting. Controlling the heating wire to continuously heat: the system continuously heats the hidden door handle by controlling the electric heating wire, and performs heating operation according to a preset first time. After the first time period is over, the system again judges whether the ice melting is successful. If the ice melting is judged to be successful, the process goes to the step S44, and returns to the normal mode; if the judgment fails, the next step is entered: the heating time period is increased along with the order of judging whether the ice melting is successful, and the heating time period can be gradually increased after each judgment of the ice melting failure. The system determines the increment of the heating duration of the next round according to the judgment times which are recorded and the set rules or algorithms. Increasing the heating period step by step helps to increase the probability of successful ice melting until it is determined that ice melting is successful and the process proceeds to step S44, or a preset maximum heating period is reached and ice melting failure is declared.
