Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of automobile accessories, in particular to a hand leaving early warning device, a vehicle and a control method of the hand leaving early warning device. BACKGROUND

[0002] Nowadays, automobiles have become necessities of people's life. When the automobile is running at high speed on the road, the driver must correctly control the steering wheel with both hands to ensure the safety of driving. However, for some new drivers who just learn to drive, they often cannot correctly hold the steering wheel due to nervousness or negligence, which will bring great safety hazards to the driving process. In addition, some skilled drivers make or receive phone calls while driving, and only use one hand to drive, or even some drivers directly release both hands, which is easy to cause safety accidents.

[0003] In the prior art, when it is detected that the driver's hands are about to leave the steering wheel, the driver is mainly prompted by vibration or beeping. The existing prompting method cannot effectively prompt the driver to place the hands on the steering wheel, and is not soft enough, which is easy to cause interference to the driver. SUMMARY

[0004] The embodiments of the present application provide a hand leaving early warning device, a vehicle and a control method of the hand leaving early warning device, which are used to improve the driving safety.

[0005] In a first aspect, a hand leaving early warning device is provided, comprising: a steering wheel, comprising: a disc body and an elastic conduit, a flexible material surface layer is arranged on the disc body, and the elastic conduit is arranged below the flexible material surface layer; a water pump, which is in communication with the elastic conduit; a pressure sensor, which is arranged between the flexible material surface layer and the elastic conduit and is used to detect a pressure value on the flexible material surface layer; and a controller, which is electrically connected with the water pump and the pressure sensor and is configured to: acquire a first pressure value on the flexible material surface layer through the pressure sensor; and control the water pump to pump out liquid in the elastic conduit to make the flexible material surface layer of the steering wheel concave in a case where it is detected that the first pressure value is less than a first pressure threshold.

[0006] According to the above, in the case that the first pressure value on the flexible material surface layer is detected to be less than the first pressure threshold, it is possible that the driver's hand is not tightly holding the steering wheel, at which time the water pump is controlled to pump the liquid in the elastic conduit out, so that the flexible material surface layer of the steering wheel is concave. It should be understood that the concave flexible material surface layer of the steering wheel will generate an adsorption feeling on the driver's hand, so that the driver's hand can be automatically adsorbed on the steering wheel by the hand leaving warning device in the case that the driver's hand is not tightly holding the steering wheel, so as to improve the driving safety. The adsorption feeling generated by the concave flexible material surface layer of the steering wheel on the driver's hand can make the driver know that the current hand may not be tightly holding the steering wheel, that is, the driver is reminded to tightly hold the steering wheel by making the flexible material surface layer of the steering wheel concave, which improves the driving safety. There is no need to use vibration or buzzer to remind the driver, which avoids the interference on the driver caused by the vibration or buzzer, and further improves the driving safety.

[0007] In some embodiments, the hand leaving warning device further includes: a containing cavity in communication with the water pump, configured to contain the liquid in the elastic conduit; and the controller, when configured to control the water pump to pump the liquid in the elastic conduit out, is specifically configured to: control the water pump to pump the liquid in the elastic conduit out to the containing cavity.

[0008] According to the above, by adding the containing cavity, the pumped liquid in the elastic conduit can be stored, so that the liquid can be quickly injected into the elastic conduit when the driver restores the safe driving state, so that the flexible material surface layer of the steering wheel becomes full, and the safe driving of the driver is further ensured.

[0009] In some embodiments, the controller is further configured to: after controlling the water pump to pump the liquid in the containing cavity into the elastic conduit, acquire a second pressure value of the flexible material surface layer through the pressure sensor; and in the case that the second pressure value is detected to be greater than or equal to the first pressure threshold, control the water pump to pump the liquid in the containing cavity into the elastic conduit, so that the flexible material surface layer enters the full state.

[0010] According to the above, in the case that the second pressure value is detected to be greater than or equal to the first pressure threshold, that is, the driver repositions the hand on the steering wheel, the water pump is controlled to pump the liquid in the containing cavity into the elastic conduit, so that the flexible material surface layer of the steering wheel returns to the full state, which avoids the influence on the driving safety caused by the uneven surface of the steering wheel.

[0011] In some embodiments, the device further comprises a voice prompt device electrically connected to the controller; and the controller is further configured to: after controlling the water pump to pump the liquid in the elastic conduit out, acquire a third pressure value of the flexible material surface layer by the pressure sensor; and if the third pressure value is not detected to be greater than the second pressure threshold within a preset time length, control the voice prompt device to play a prompt information, the prompt information being used to prompt the user to drive safely.

[0012] According to the above, the voice prompt device is added, and the prompt information is played to remind the driver to drive safely if the third pressure value is not detected to be greater than the second preset threshold, so that the driving safety performance is further enhanced.

[0013] In a second aspect, a vehicle is provided, comprising the hand-off early warning device of the first aspect.

[0014] In a third aspect, a control method of a hand-off early warning device is provided, comprising: acquiring a first pressure value on a flexible material surface layer of a steering wheel by a pressure sensor; and in a case where the first pressure value is detected to be less than a first pressure threshold, controlling a water pump to pump liquid in an elastic conduit of the steering wheel out, so that the flexible material surface layer of the steering wheel is concave.

[0015] In some embodiments, the controlling the water pump to pump the liquid in the elastic conduit of the steering wheel out comprises: controlling the water pump to pump the liquid in the elastic conduit to a containing cavity.

[0016] In some embodiments, after the water pump is controlled to pump the liquid in the elastic conduit to the containing cavity, a second pressure value of the flexible material surface layer is acquired by the pressure sensor; and in a case where the second pressure value is detected to be greater than or equal to the first pressure threshold, the water pump is controlled to pump the liquid in the containing cavity into the elastic conduit, so that the flexible material surface layer enters a full state.

[0017] In some embodiments, after the water pump is controlled to pump the liquid in the elastic conduit out, a third pressure value of the flexible material surface layer is acquired; and in a case where the third pressure value is not detected to be greater than a second pressure threshold within a preset time length, a prompt information is sent, the prompt information being used to prompt the user to drive safely.

[0018] In a fourth aspect, a computer readable storage medium is provided, when instructions in the computer readable storage medium are executed by a processor of a vehicle, the vehicle is enabled to perform the method of the third aspect and any of its embodiments.

[0019] In a fifth aspect, a computer program product is provided, the computer program product comprising computer instructions, when the computer instructions are run on a vehicle, the vehicle is enabled to perform the method of the third aspect and any of its embodiments.

[0020] Therefore, the above technical features of the present application have the following beneficial effects:

[0021] (1) In the case that the first pressure value on the flexible material surface layer is less than the first pressure threshold, it is possible that the driver's hand is not tightly holding the steering wheel. At this time, the water pump is controlled to pump the liquid in the elastic conduit out, so that the flexible material surface layer of the steering wheel is concave. It should be understood that the concave of the flexible material surface layer of the steering wheel will generate an adsorption feeling to the driver's hand, so that the driver's hand can be automatically adsorbed on the steering wheel in the case that the driver's hand is not tightly holding the steering wheel, so as to improve the driving safety. And the adsorption feeling generated by the concave of the flexible material surface layer of the steering wheel to the driver's hand can make the driver know that the current hand may not be tightly holding the steering wheel, that is, the driver is reminded to tightly hold the steering wheel by making the flexible material surface layer of the steering wheel concave, which improves the driving safety. Without using vibration or beeping to remind the driver, the interference to the driver caused by the vibration or beeping is avoided, and the driving safety is further improved.

[0022] (2) By increasing the accommodating cavity, the pumped liquid in the elastic conduit can be stored, so that the liquid can be quickly injected into the elastic conduit when the driver restores the safe driving state, so that the flexible material surface layer of the steering wheel becomes full, and the safe driving of the driver is further ensured.

[0023] (3) In the case that the second pressure value is greater than or equal to the first pressure threshold, the liquid in the accommodating cavity is pumped into the elastic conduit by controlling the water pump, so that the flexible material surface layer of the steering wheel returns to the full state, and the influence of the uneven surface of the steering wheel on the driving safety is avoided.

[0024] (4) The voice prompting device is increased, which can play the prompt information to remind the driver to drive safely in the case that the third pressure value is not detected to be above the second preset threshold, and the driving safety performance is further enhanced.

[0025] It should be noted that the technical effects brought by any one of the implementation manners of the second aspect to the fifth aspect can be referred to the technical effects brought by the corresponding embodiments in the first aspect, which will not be repeated here.

[0026] It should be understood that the above general description and the following detailed description are only exemplary and explanatory, and cannot limit the present application. BRIEF DESCRIPTION OF DRAWINGS

[0036] In order to make the ordinary person skilled in the art better understand the technical solutions of the present application, the technical solutions in the embodiments of the present application will be described clearly and completely below with reference to the drawings.

[0037] It should be noted that the terms "first", "second", etc. in the specification and claims of the present application and the above-mentioned drawings are used to distinguish similar objects, and do not necessarily describe a specific order or sequence. It should be understood that the data used in this way can be interchanged under appropriate circumstances, so that the embodiments of the present application described herein can be implemented in an order other than those illustrated or described herein. The embodiments described in the following exemplary embodiments do not represent all embodiments consistent with the present application. Rather, they are merely examples of devices and methods consistent with some aspects of the present application as detailed in the appended claims.

[0038] Nowadays, cars have become a necessity in people's lives. When a car is traveling at high speed on the road, the driver must properly control the steering wheel to ensure driving safety. However, some novice drivers often fail to hold the steering wheel correctly due to nervousness or negligence, which can create significant safety hazards. Furthermore, some skilled drivers use their phones while driving, drive with only one hand, or even completely let go of the steering wheel; a moment's inattention can lead to a fatal accident, bringing disaster to the family.

[0039] In existing technologies, when a driver's hands are detected to have left the steering wheel, vibration, beeping, or voice prompts are primarily used to alert the driver. However, these existing methods are not effective in encouraging the driver to place their hands back on the steering wheel, and are not gentle enough, potentially causing driver distraction.

[0040] The hands-off warning device provided in this application embodiment may include: a steering wheel 101.

[0041] In some embodiments, see Figure 1 As shown, the steering wheel 101 includes: a disc body 1011 and an elastic conduit 1012. A flexible material surface layer 1013 is provided on the disc body, and the elastic conduit 1012 is placed under the flexible material surface layer 1013.

[0042] In some embodiments, see Figure 1 As shown, the steering wheel 101 also includes a pressure sensor 1014; the pressure sensor 1014 is disposed between the elastic conduit 1012 and the flexible material surface layer 1013; the pressure sensor 1014 is used to detect the pressure value on the flexible material surface layer 1013.

[0043] See Figure 2 As shown, the off-hand warning device provided in this application embodiment further includes: a water pump 102; the water pump 102 and the elastic conduit 1012 are connected.

[0044] See Figure 2 As shown, the off-hand warning device provided in this application embodiment further includes: a receiving cavity 103; the receiving cavity 103 may be a water storage device such as a water bladder or water tank, and this application does not make specific limitations on it; the receiving cavity 103 is connected to the water pump 102.

[0045] See Figure 3 As shown in the embodiment of this application, the off-hand warning device also includes a voice prompt device 104.

[0046] See Figure 3 As shown, the off-hand warning device provided in this application embodiment further includes: a controller 105, which is electrically connected to a pressure sensor 1014, a water pump 102 and a voice prompt device 104.

[0047] In some embodiments, the controller 105 refers to a device that can generate operation control signals according to instruction operation codes and timing signals, instructing the hand-off early warning device to execute control instructions. Exemplarily, the controller 105 can be a central processing unit (CPU), a general processor network processor (NP), a digital signal processing (DSP), a microprocessor, a microcontroller, a programmable logic device (PLD), or any combination thereof. The controller 105 can also be other devices with processing functions, such as a circuit, a device, or a software module, and the embodiments of the present application do not make any limitation thereto.

[0048] In some embodiments, the controller 105 is configured to: acquire, by the pressure sensor 1014, a first pressure value on the flexible material surface layer 1013; and control the water pump 102 to pump out the liquid in the elastic conduit 1012 to make the flexible material surface layer 1013 of the steering wheel 101 concave, in a case where it is detected that the first pressure value is less than a first pressure threshold.

[0049] According to the above, in a case where the first pressure value acquired by the pressure sensor is less than the first preset threshold, the flexible material surface layer of the steering wheel is made to concave by pumping out the liquid in the elastic conduit, the driver's hand is attracted when the flexible material surface layer is concave, that is, the driver is prompted to place the hand on the steering wheel, and the vibration, buzzer, or voice prompt mode is avoided to cause interference to the driver.

[0050] In some embodiments, when the controller 105 is configured to control the water pump 102 to pump out the liquid in the elastic conduit 1012, the controller 105 is specifically configured to: control the water pump 102 to pump out the liquid in the elastic conduit 1012 to the containing cavity 103.

[0051] According to the above, the liquid in the elastic conduit is pumped out to the containing cavity, and the liquid in the elastic conduit is stored, so that the driver can quickly inject the liquid into the elastic conduit when the driver recovers to the safe driving state, the flexible material surface layer of the steering wheel becomes full, and the safe driving of the driver is further ensured.

[0052] In some embodiments, the controller 105 is further configured to: after controlling the water pump 102 to pump the liquid in the elastic conduit 1012 out to the containing cavity 103, acquire a second pressure value of the flexible material surface layer 1013 by the pressure sensor 1014; and in a case where the second pressure value is greater than or equal to a first pressure threshold, control the water pump 102 to pump the liquid in the containing cavity 103 into the elastic conduit 1012, so that the flexible material surface layer 1013 enters a full state.

[0053] According to the above, in a case where the second pressure value is greater than or equal to the first pressure threshold, the water pump is controlled to pump the liquid in the containing cavity into the elastic conduit, so that the flexible material surface layer of the steering wheel returns to the full state, and the uneven surface of the steering wheel does not affect the driving safety.

[0054] In some embodiments, the controller 105 is further configured to: after controlling the water pump 102 to pump the liquid in the elastic conduit 1012 out, acquire a third pressure value of the flexible material surface layer 1013 by the pressure sensor 1014; and if the third pressure value is not detected to be above a second pressure threshold within a preset time length, control the voice prompt device 104 to play prompt information, the prompt information being used to prompt the user to drive safely.

[0055] According to the above, the voice prompt device is added, and in a case where the third pressure value is not detected to be above the second preset threshold, the prompt information is played to remind the driver to drive safely, and the driving safety performance is further enhanced.

[0056] Based on the above hand-off early warning device, as shown in Figure 4 The embodiment of the present application provides a control method of a hand-off early warning device, and the method comprises the following steps:

[0057] S101, acquiring a first pressure value on a flexible material surface layer of a steering wheel.

[0058] In some embodiments, the first pressure value on the flexible material surface layer of the steering wheel is acquired during driving of the vehicle, so as to determine whether the hand of the driver is on the steering wheel.

[0059] S102, in a case where the first pressure value is less than a first pressure threshold, controlling a water pump to pump liquid in an elastic conduit of the steering wheel out, so that the flexible material surface layer of the steering wheel is recessed.

[0060] The first pressure threshold can be preset when the vehicle is manufactured, for example, the first pressure threshold is a pressure value when the hand of the driver is about to leave the flexible material surface layer of the steering wheel.

[0061] In some embodiments, the control of the water pump to pump out the liquid in the elastic conduit of the steering wheel can be specifically implemented as pumping out the liquid in the elastic conduit to the containing cavity.

[0062] It should be understood that the pumping of the elastic conduit into the containing cavity can store the liquid in the elastic conduit by the containing cavity, so as to ensure that the liquid in the containing cavity can be quickly pumped into the elastic conduit when the driver restores the safe driving state, so that the flexible material surface layer of the steering wheel is full, and the safe driving of the driver is further ensured.

[0063] From the above, in the above method provided by the embodiments of the present application, in the case where the first pressure value on the flexible material surface layer is less than the first pressure threshold, it is represented that the hand of the driver can not be tightly gripped on the steering wheel, at this time, the water pump is controlled to pump out the liquid in the elastic conduit, so that the flexible material surface layer of the steering wheel is recessed. It should be understood that the recess of the flexible material surface layer of the steering wheel will generate an adsorption feeling to the hand of the driver, so that the hand of the driver can be automatically adsorbed on the steering wheel by the hand pre-warning device in the case where the hand is not tightly gripped on the steering wheel, so as to improve the driving safety. And the adsorption feeling generated by the recess of the flexible material surface layer of the steering wheel to the hand of the driver can make the driver know that the hand can not be tightly gripped on the steering wheel at present, that is, the driver is reminded to tightly grip the hand on the steering wheel by making the flexible material surface layer of the steering wheel recess, so as to improve the driving safety; without using the vibration or the buzzer to remind the driver, the interference to the driver caused by the vibration or the buzzer is avoided, and the driving safety is further improved.

[0064] In some embodiments, referring to Figure 5 It is shown that in the case where the driver normally drives, the flexible material surface layer of the steering wheel is in a full state; if the first pressure value is less than the first pressure threshold, it is determined that the hand of the driver can be leaving the steering wheel; at this time, the water pump is controlled to pump out the liquid in the elastic conduit of the steering wheel, so that the flexible material surface layer of the steering wheel is recessed, and the flexible material surface layer of the steering wheel generates an adsorption feeling to the hand of the driver, so as to remind the driver to place the hand on the steering wheel.

[0065] In some embodiments, if the target vehicle is in an automatic driving state, in the case where the first pressure value is less than the first pressure threshold, the water pump is controlled to pump out the liquid in the elastic conduit of the steering wheel to the containing cavity, so that the flexible material surface layer of the steering wheel generates an adsorption feeling to the hand of the driver, and the target vehicle is controlled to slow down at the same time.

[0066] It can be known from the above that, in the method provided in the embodiment of the application, in the process of automatic driving of the vehicle, if the first pressure is less than the first pressure threshold, that is, the driver's hand is away from the steering wheel, the vehicle is controlled to slow down while reminding the driver to drive safely, and the driving safety is further improved.

[0067] Referring to Figure 6 As shown in the figure, the control method of the hand-off early warning device provided in the embodiment of the application further includes the following steps:

[0068] S201, after controlling the water pump to pump the liquid in the elastic conduit to the containing cavity, a second pressure value of the flexible material surface layer is acquired.

[0069] In some embodiments, after pumping the liquid in the elastic conduit to the containing cavity, in order to detect whether the driver places the hand on the steering wheel again, a second pressure value of the flexible material surface layer of the steering wheel is acquired; and whether the driver places the hand on the steering wheel again is judged according to the second pressure value.

[0070] S202, in the case that the second pressure value is greater than or equal to the first pressure threshold, the water pump is controlled to pump the liquid in the containing cavity into the elastic conduit, so that the flexible material surface layer enters the full state.

[0071] In some embodiments, referring to Figure 7 As shown in the figure, after the flexible material surface of the steering wheel is concave, in the case that the driver holds the steering wheel tightly again and the pressure sensor detects that the second pressure value is greater than or equal to the first pressure threshold, the water pump is controlled to pump the liquid in the containing cavity into the elastic conduit, so that the flexible material surface layer enters the full state.

[0072] It should be understood that, in the case that the second pressure value is greater than or equal to the first pressure threshold, that is, the driver places the hand on the steering wheel again, the water pump can be controlled to pump the liquid in the containing cavity into the elastic conduit of the steering wheel, so that the flexible material surface layer of the steering wheel is full, and the driving safety is improved.

[0073] It should be explained that, if the driver places the hand on the steering wheel again, if the flexible material surface layer of the steering wheel does not recover to the full state, the surface of the steering wheel can be uneven, and thus the driving safety can be affected.

[0074] In some embodiments, as Figure 8 As shown in the figure, the hand-off early warning method provided in the embodiment of the application can further include the following steps after step S201:

[0075] S203, after controlling the water pump to pump the liquid in the elastic conduit, a third pressure value of the flexible material surface layer is acquired.

[0076] It should be understood that, after the water pump is controlled to pump the liquid in the elastic conduit out, the third pressure value of the flexible material surface layer is acquired to detect whether the user places the hand on the steering wheel.

[0077] S204, in a case where the third pressure value is not detected to be greater than the second pressure threshold within a preset time length, issuing a prompt information.

[0078] In some embodiments, the preset time length and the second pressure threshold can be preset when the vehicle is manufactured.

[0079] It should be understood that, if the third pressure value is not detected to be greater than the second pressure threshold within the preset time length, it indicates that the driver does not place the hand on the steering wheel for a long time.

[0080] In some embodiments, in a case where the third pressure value is not detected to be greater than the second pressure threshold within the preset time length, i.e., the driver does not place the hand on the steering wheel within the preset time length, the prompt information is issued by using a voice prompt device.

[0081] It should be understood that the prompt information can be voice content such as "please drive safely", and the present application does not make a specific limitation.

[0082] It can be seen that the above mainly introduces the scheme provided by the embodiments of the present application from the perspective of the method.
