[0040] In order to make the purposes, technical solutions and advantages of the present application clearer, the present application will be further described in detail below with reference to the drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present application and not to limit the present application.
[0041] In an embodiment, as shown in Figure 1 a door handle opening method of a vehicle is provided, and the present embodiment takes the method applied to a controller of the vehicle as an example. In the present embodiment, the method comprises the following steps:
[0042] Step 102, receiving a touch sensing signal sent by an elastic wave sensor, the touch sensing signal being generated when the elastic wave sensor detects a user touch operation;
[0043] In the present embodiment, the elastic wave sensor is a kind of skin sensor, whose principle is to monitor the tiny deformation caused by hitting or pressing the surface of an object. When the elastic wave sensor senses a user touch operation, a frequency signal is generated based on the sensed signal, the frequency signal being taken as a touch sensing signal, and the touch sensing signal being sent to the controller of the vehicle. The controller can analyze the touch sensing signal and extract useful information.
[0044] The elastic wave sensor can be installed in the door handle of the vehicle or other areas of the vehicle.
[0045] When the elastic wave sensor is installed in the door handle of the vehicle, the user touch operation can be specifically: the user presses the door handle of the vehicle, and the pressing duration exceeds a preset pressing duration threshold, or the user slides on the door handle of the vehicle, and the sliding duration exceeds a preset sliding duration threshold.
[0046] In the embodiment, the vehicle door handle can be a hidden handle, which is embedded in the door panel or designed in a way of reverse slope, gutter, etc. to make the vehicle look simple and neat.
[0047] In the embodiment, the elastic wave sensor is obviously different from the traditional pressure sensor. The elastic wave sensor mainly converts the sensed user operation signal into a frequency spectrum signal and outputs frequency spectrum data. After sensing the user operation, the pressure sensor usually outputs a direct electric signal, which can be directly read and converted into a pressure value to determine the pressure change.
[0048] In step 104, the door handle of the vehicle is controlled to be opened based on the touch sensing signal.
[0049] The controller controls the door handle of the vehicle to be opened based on the useful information in the extracted touch sensing signal.
[0050] It should be noted that in the case that the ambient temperature of the vehicle is lower than the temperature threshold, the hidden door handle can be frozen and cannot be opened. Therefore, after the door handle of the vehicle is controlled to be opened, the door handle of the vehicle can fail to be opened.
[0051] In step 106, in the case that the door handle fails to be opened, it is determined whether the number of received touch sensing signals exceeds a preset first number threshold.
[0052] The elastic wave sensor can detect the user touch operation one or more times and generate touch sensing signals and send them to the elastic wave sensor before the controller receives the current touch sensing signal. Therefore, the number of received touch sensing signals refers to the total number of the current touch sensing signal and one or more touch sensing signals received by the elastic wave sensor before the time when the current touch sensing signal is received.
[0053] For example, the elastic wave sensor receives 5 touch sensing signals before the time when the current touch sensing signal is received, and then the current touch sensing signal is received. Therefore, the number of received touch sensing signals is 6.
[0054] In step 108, in the case that the first number threshold is exceeded, the door handle is heated for a preset heating duration, and the door handle is controlled to be opened after the heating of the door handle is completed.
[0055] In the embodiment, one of the preset heating durations can be selected based on the number of received touch sensing signals, and the door handle is heated for the selected preset heating duration.
[0056] The selected preset heating duration can be different when the number of received touch sensing signals is different.
[0057] In the embodiment, a heating wire can be installed in the door handle of the vehicle, and the controller controls the heating wire to generate heat to heat the door handle when the number of received touch sensing signals exceeds a first number threshold.
[0058] The controller can interactively communicate with the drive motor controller, and the controller sends a signal to open the door handle to the drive motor controller, and the drive motor controller sends the signal to the drive motor, and the drive motor controls the door handle to expand laterally to a specified expansion angle.
[0059] Of course, in the scenario of closing the door handle, the drive motor can also control the door handle to contract to a specified contraction angle.
[0060] The application can receive the touch sensing signals sent by the elastic wave sensor, and the touch sensing signals are generated when the elastic wave sensor detects a user touch operation, so as to control the door handle of the vehicle to open based on the touch sensing signals. In the case that the door handle fails to open, it is considered that there is a situation that the hidden door handle cannot be opened in a low temperature environment, and then it can be judged whether the number of received touch sensing signals exceeds a preset first number threshold. In the case that the first number threshold is exceeded, the door handle is heated for a preset heating time, and the door handle is controlled to open after the heating of the door handle is completed. The door handle is heated in a low temperature environment, so that the door handle can be controlled to open after heating, and the problem of how to open the hidden door handle in a low temperature environment is solved.
[0061] In one of the embodiments, the heating operation of the door handle for the preset heating time includes: judging whether the number of received touch sensing signals exceeds a preset second number threshold; in the case that the second number threshold is exceeded, the door handle is heated for a preset first heating time; in the case that the second number threshold is not exceeded, the environmental parameter of the environment where the vehicle is located is obtained, the target heating time is selected from the preset second heating time based on the environmental parameter, and the door handle is heated for the target heating time.
[0062] The second number threshold is greater than the first number threshold. In the case that the number of received touch sensing signals exceeds the preset first number threshold, it is further judged whether the number of received touch sensing signals exceeds the preset second number threshold. In the case that the second number threshold is exceeded, the door handle (or the door handle touched by the user) in the vehicle is directly heated for a preset first heating time, and the corresponding door handle is controlled to open after the heating of the door handle is completed.
[0063] In a case where the number of received touch sensing signals does not exceed a second quantity threshold, an environment parameter of an environment in which the vehicle is located is acquired. In this embodiment, the environment parameter of the environment in which the vehicle is located includes an environment temperature and / or an environment humidity.
[0064] The second preset heating duration includes at least two heating durations, and specifically includes a first heating duration. A target heating duration corresponding to the environment parameter can be selected from the second preset heating duration based on the environment parameter, so that the door handle is heated for the target heating duration.
[0065] The target heating duration corresponding to the environment parameter can be the first heating duration.
[0066] In this embodiment, the target heating duration corresponding to different environment parameters can be different. Specifically,
[0067] When the environment temperature belongs to a range of T1 to T2 and the environment humidity belongs to a range of RH1 to RH2, the first heating duration is selected from the second preset heating duration. For example, T1 to T2 can be -1℃ to 2℃, RH1 to RH2 can be 60% to 80%, and the first heating duration is 5min.
[0068] When the environment temperature belongs to a range of T2 to T3 and the environment humidity belongs to a range of RH2 to RH3, the third heating duration is selected from the second preset heating duration, and the third heating duration is greater than the first heating duration. For example, T2 to T3 can be -15℃ to -1℃, RH2 to RH3 can be 80% to 100%, and the third heating duration is 10min.
[0069] It can be seen that, based on the number of received touch sensing signals and the environment parameter, the corresponding preset heating duration can be determined, so that the door handle is heated according to different preset heating durations, and accurate control of the door handle heating duration is achieved.
[0070] In existing vehicles using hidden door handles, based on the Internet of Vehicles state and the environment parameter, whether the door handle needs to be heated to ensure that the hidden door handle automatically pops out is monitored, but this scheme acquires the environment parameter through an information platform and heats the door handle before the user approaches the vehicle, which requires high network connection resources, and cannot monitor the environment parameter based on the actual vehicle scene, so the environment parameter is not accurate enough.
[0071] In one of the embodiments, the acquiring the environment parameter of the environment in which the vehicle is located includes: receiving an environment temperature of the environment in which the vehicle is located sent by a temperature sensor; receiving an environment humidity of the environment in which the vehicle is located sent by a humidity sensor; and taking the environment temperature and the environment humidity as the environment parameter.
[0072] The application can install a temperature (T) sensor and an environment humidity (RH) sensor on the vehicle, sense the environment temperature of the environment where the vehicle is located in real time through the temperature sensor, sense the environment humidity of the environment where the vehicle is located in real time through the humidity sensor, send the sensed environment temperature to the controller by the temperature sensor, send the sensed environment humidity to the controller by the humidity sensor, and take the environment temperature and the environment humidity as the environment parameters by the controller.
[0073] It can be seen that the application can monitor the real-time environment parameters through the temperature sensor and the humidity sensor, can detect the environment parameters of the actual vehicle scene, improves the accuracy of the environment parameter detection, and thus the heating time length of the door handle determined is more accurate. Meanwhile, the environment parameters can be directly detected by the sensors installed on the vehicle, without the need of high network connection resources to obtain the environment parameters from the information platform, and the requirement for network connection is reduced.
[0074] As described above, in the case that the number of received touch sensing signals does not exceed the preset first number threshold, the touch sensing signals sent by the elastic wave sensor can be received repeatedly for multiple times until the preset first number threshold is exceeded, and the door handle is heated to open the door handle. Specifically, the method comprises the following steps:
[0075] In one of the embodiments, the receiving of the touch sensing signals sent by the elastic wave sensor comprises: detecting an unlocking signal of the vehicle; and in the case that the unlocking signal is detected, receiving the touch sensing signals sent by the elastic wave sensor.
[0076] In one of the embodiments, the method further comprises: in the case that the number of received touch sensing signals does not exceed the first number threshold, returning to the step of detecting the unlocking signal of the vehicle and continuing to execute until the number of received touch sensing signals exceeds the preset first number threshold.
[0077] The controller detects the unlocking signal of the vehicle, specifically comprising: a door lock controller sensing a key signal, controlling whether the vehicle is unlocked or locked, and sending the unlocking signal of the vehicle to the controller after the door lock controller detects the unlocking of the vehicle.
[0078] The unlocking signal of the vehicle is detected, the touch sensing signal sent by the elastic wave sensor is received in the case that the unlocking signal is detected, the door handle of the vehicle is controlled to be opened based on the touch sensing signal, it is judged whether the door handle is successfully opened, in the case that the door handle is failed to be opened, it is judged whether the number of the received touch sensing signals exceeds a preset first number threshold, in the case that the first number threshold is not exceeded, the following steps are returned to the cycle: the unlocking signal of the vehicle is detected, the touch sensing signal sent by the elastic wave sensor is received in the case that the unlocking signal is detected, the door handle of the vehicle is controlled to be opened based on the touch sensing signal, it is judged whether the door handle is successfully opened, in the case that the door handle is failed to be opened, it is judged whether the number of the received touch sensing signals exceeds a preset first number threshold, until the number of the received touch sensing signals exceeds the preset first number threshold or the door handle is successfully opened; in the case that the first number threshold is exceeded, the door handle is heated for a preset heating time, and the door handle is controlled to be opened after the heating of the door handle is completed.
[0079] It can be seen that, in the case that the number of the received touch sensing signals does not exceed the preset first number threshold, the touch sensing signal sent by the elastic wave sensor can be repeatedly received multiple times, so that the door handle is opened after being heated, and the error opening of the door handle caused by the user's accidental touch of the door handle is avoided.
[0080] Meanwhile, the unlocking signal of the vehicle needs to be detected every cycle, and the touch sensing signal sent by the elastic wave sensor is received in the case that the unlocking signal is detected, so that the door handle is prevented from being erroneously opened in the case that the vehicle is not unlocked, and the driving safety is ensured.
[0081] In the present application, after the door handle is heated for a preset heating time, the door handle may still be unable to be opened after being heated, and the door handle can be heated again to be opened, specifically:
[0082] In one of the embodiments, after the door handle is controlled to be opened after the heating of the door handle is completed, the method comprises: in the case that the door handle is still failed to be opened, returning to the step of judging whether the number of the received touch sensing signals exceeds a preset first number threshold, until the door handle is successfully opened.
[0083] It is judged whether the door handle is successfully opened, and the cycle is ended in the case that the door handle is still successfully opened;
[0084] In the case that the door handle is still failed to open, the following steps are cyclically executed: judging whether the number of received touch sensing signals exceeds a preset first number threshold; in the case that the first number threshold is exceeded, performing a heating operation on the door handle according to a preset heating duration, and controlling the door handle to open after the heating of the door handle is completed until the door handle is successfully opened.
[0085] In the embodiment, in the case that the number of received touch sensing signals exceeds the preset first number threshold, the number of received touch sensing signals does not change, i.e., the number of received touch sensing signals does not change in each cycle, and still exceeds the first number threshold.
[0086] Similarly, the specific implementation of the heating operation on the door handle according to the preset heating duration is referred to the corresponding description in the above embodiment, and will not be described here.
[0087] It can be seen that, after the door handle is heated according to the preset heating duration for the first time, if the door handle is still failed to open, the step of judging whether the number of received touch sensing signals exceeds the preset first number threshold is cyclically executed, so that the door handle is heated according to the preset heating duration again or multiple times, thereby ensuring that the door handle is normally opened.
[0088] Reference Figure 2 The figure is a structure diagram of the vehicle, which includes a door lock controller, a temperature and humidity sensor, a skin sensor controller (also called a skin wave controller), a driving motor controller, a driving motor, four skin sensors (i.e., skin wave sensors), a heating wire, and a display screen. The four skin sensors, the heating wire, and the display screen are integrally installed on the door handle.
[0089] The skin sensor is installed on the door handle and is used to sense the pressure change of the door handle and transmit the sliding sensing signal to the skin controller. The heating wire is installed on the door handle and heats the door handle after receiving the heating signal. The driving motor controls the door handle to expand or contract horizontally after receiving the driving motor control signal. The driving motor controller and the skin sensor controller interact with the expansion state of the door handle. The temperature and humidity sensor detects the temperature and humidity of the environment where the vehicle is located in real time and transmits the signal to the skin sensor controller. The door lock controller senses the key signal and controls whether the vehicle is unlocked or locked. The skin sensor controller controls whether the door handle expands and the heating requirement based on the expansion state of the door handle, the temperature and humidity of the environment, the door lock state, and the skin sensor signal state. The display screen reminds whether the door handle is being heated.
[0090] The skin sensor controller is used for logical processing after collecting all skin sensor signals, and outputs corresponding electrical signal functions; the door lock controller is used for monitoring vehicle key signals, judging whether there is a door opening demand, and making the vehicle unlock or enter an unlockable state.
[0091] As shown in the flowchart of the overall scheme of the present application, the overall scheme is as follows: Figure 3
[0092] The controller detects the key unlocking signal, and if no key unlocking signal is detected, the cycle process of sensing finger sliding is ended.
[0093] If the key unlocking signal is detected, the skin sensor senses the door handle pressure or senses the finger sliding, and if no door handle pressure or finger sliding is sensed, the cycle process of sensing finger sliding is ended.
[0094] If the door handle pressure or finger sliding is sensed, it is judged whether the driving motor drives the handle door to the specified door opening angle, and if the driving motor drives the handle door to the specified door opening angle, the cycle process of sensing finger sliding is ended.
[0095] If the driving motor does not drive the handle door to the specified door opening angle, it is judged whether the user sliding times are one or two times of sliding.
[0096] If the user sliding times are one or two times of sliding, the cycle process of finger sliding is executed, which specifically includes the steps of detecting the key unlocking signal, if no key unlocking signal is detected, ending the cycle process of sensing finger sliding, if the key unlocking signal is detected, the skin sensor senses the door handle pressure or senses the finger sliding, if no door handle pressure or finger sliding is sensed, ending the cycle process of sensing finger sliding, if the door handle pressure or finger sliding is sensed, it is judged whether the driving motor drives the handle door to the specified door opening angle, if the driving motor drives the handle door to the specified door opening angle, ending the cycle process of sensing finger sliding, and if the driving motor does not drive the handle door to the specified door opening angle, it is judged whether the user sliding times are one or two times of sliding, until the result of the judgment is that the user sliding times exceed two times.
[0097] After the user sliding times exceed two times, it is judged whether the user sliding times are three or more times of sliding, and if the user sliding times are three or more times of sliding, the four door handles are heated according to the heating time length time1, and the display screen displays that the door handle is heating, please wait.
[0098] If the number of user swipes is three, the ambient temperature is acquired by the temperature sensor, the ambient humidity is acquired by the humidity sensor, and it is determined whether the ambient temperature meets the heating requirement. If yes, when the ambient temperature belongs to the range of T2 to T3 and the ambient humidity belongs to the range of RH2 to RH3, the four door handles are heated according to the heating duration time2, and when the ambient temperature belongs to the range of T1 to T2 and the ambient humidity belongs to the range of RH1 to RH2, the four door handles are heated according to the heating duration time1, and the display screen displays that the door handle is being heated, please wait.
[0099] No matter whether the four door handles are heated according to the heating duration time1, or the heating duration time2 when the ambient temperature belongs to the range of T2 to T3 and the ambient humidity belongs to the range of RH2 to RH3, or the heating duration time1 when the ambient temperature belongs to the range of T1 to T2 and the ambient humidity belongs to the range of RH1 to RH2, after the heating is completed, it is necessary to return to determine whether the driving motor drives the door handle to the specified opening angle. If the door handle has reached the specified opening angle, the heating cycle is ended, and if the door handle has not reached the specified opening angle, the heating cycle is performed. The heating cycle specifically includes the following steps: it is determined whether the number of user swipes is more than three times; if the number of user swipes is more than three times, the four door handles are heated according to the heating duration time1, and the display screen displays that the door handle is being heated, please wait; if the number of user swipes is three, the ambient temperature is acquired by the temperature sensor, the ambient humidity is acquired by the humidity sensor, and it is determined whether the ambient temperature meets the heating requirement. If yes, when the ambient temperature belongs to the range of T2 to T3 and the ambient humidity belongs to the range of RH2 to RH3, the four door handles are heated according to the heating duration time2, and when the ambient temperature belongs to the range of T1 to T2 and the ambient humidity belongs to the range of RH1 to RH2, the four door handles are heated according to the heating duration time1, and the display screen displays that the door handle is being heated, please wait.
[0100] For example, if the number of received touch sensing signals is 4, which exceeds the preset first number threshold 2 and the preset second number threshold 3, the four door handles are heated according to the heating duration time1. After the heating is completed, if the door handle has not been opened to the specified opening angle, the heating cycle is returned. At this time, the number of received touch sensing signals is still 4, which exceeds the preset first number threshold 2 and the preset second number threshold 3. Therefore, the four door handles are still heated according to the heating duration time1. After the heating is completed, it is determined that the door handle has been opened to the specified opening angle. Therefore, the total heating duration of the door handle is time1+time1.
[0101] In the embodiment, T1 to T2 can be -1℃ to 2℃, T2 to T3 can be -15℃ to -1℃, RH1 to RH2 can be 60% to 80%, RH3 to RH2 can be 100% to 80%, Timer1 can be 5 minutes, and Timer2 can be 10 minutes.
[0102] It can be seen that the application can more compactly and efficiently complete the door handle opening and low-temperature heating function by adopting four small aircraft skin sensors and a controller integrated on an existing vehicle, without the need for a high network environment, and can solve the problem of how to open a hidden door handle in a low-temperature environment for a driver or passenger.
[0103] The application can determine the door handle heating duration based on the real-time collected ambient temperature and ambient humidity, can collect the ambient temperature and ambient humidity of the actual scene of the vehicle, and the collected environmental parameters are more accurate, so that the determined heating duration is also more accurate.
[0104] The application can monitor the door handle pressure change through the aircraft skin sensor sliding technology, can slide once or multiple times, and customize the door handle opening and heating requirements; meanwhile, the application does not need to additionally drill holes or design buttons on the door handle, does not need to increase the size of the door handle, and does not affect the appearance.
[0105] Compared with opening the door handle by password or mechanical button or remote network, the application opens the door handle after detecting the user's touch operation by the elastic wave sensor, which is more convenient; compared with opening the door handle by voice recognition or non-contact radio frequency identification (near field communication, NFC) key, the application installs the elastic wave sensor on the door handle, which is lower in cost,
[0106] It should be understood that, although each step in the flowchart involved in each embodiment as described above is displayed in sequence according to the arrow indication, these steps are not necessarily executed in sequence according to the arrow indication. Unless explicitly stated herein, the execution of these steps is not strictly limited in sequence, and these steps can be executed in other sequences. Moreover, at least part of the steps in the flowchart involved in each embodiment as described above can include multiple steps or stages, which are not necessarily executed at the same time, but can be executed at different times, and the execution sequence of these steps or stages is not necessarily sequential, but can be executed in rotation or alternation with at least part of other steps or steps or stages in other steps.
