DETAILED DESCRIPTION

[0042] In order to make the purpose, technical solutions and advantages of this application more clearly understood, the present application is further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain this application and are not intended to limit this application.

[0043] In the description of this application, it should be understood that, unless otherwise clearly specified and limited, the terms "upper", "lower", "left", "right", etc. indicating directions or positional relationships are based on the directions or positional relationships shown in the accompanying drawings. This is only for the convenience of describing this application and simplifying the description, and does not indicate or imply that the device or element referred to must have a specific direction, be constructed and operated in a specific direction. Therefore, the terms describing the positional relationship in the drawings are only used for illustrative purposes and cannot be understood as limiting this patent. For ordinary technicians in this field, the specific meanings of the above terms can be understood according to specific circumstances.

[0044] In addition, the terms "first" and "second" are used for descriptive purposes only and should not be understood to imply or suggest relative importance or implicitly indicate the number of technical features indicated. Therefore, a feature defined as "first" or "second" may explicitly or implicitly include one or more of the features. In the description of this application, "plurality" means at least two, such as two, three, etc., unless otherwise specifically defined.

[0045] In the description of this application, unless otherwise expressly specified or limited, terms such as "installed," "connected," "connect," and "fixed" should be understood in a broad sense. For example, they can refer to fixed connections, detachable connections, or integration; mechanical connections or electrical connections; direct connections or indirect connections through an intermediate medium; and internal communication between two components or interaction between two components, unless otherwise expressly limited. Those skilled in the art will understand the specific meanings of the above terms in this application based on specific circumstances.

[0046] At present, vehicles have been widely popularized in ordinary families and integrated into people's daily lives, and people use vehicles to travel more and more frequently.

[0047] When driving a vehicle, people may inevitably encounter inclement weather or unavoidable dangers, which may cause the vehicle doors to become blocked. For example, if the driver mistakenly causes the vehicle to fall into water, the water pressure will seal the door tightly, making it impossible for the driver to open the door. This makes it difficult for people to escape the vehicle in time, which is not conducive to improving driving safety.

[0048] Based on the above problems, the present application proposes a vehicle steering wheel control method and its system, control device, and vehicle, so as to improve the safety of human driving.

[0049] like Figures 1 to 3 As shown, the steering wheel 100 is connected to the steering column 300 via a locking mechanism 200. The vehicle steering wheel control method includes:

[0050] Get the vehicle's current water depth;

[0051] Determine the relationship between the current water depth and the preset depth;

[0052] If the current water depth is greater than or equal to the preset depth, the locking mechanism 200 is controlled to be in an unlocked state so that the steering wheel 100 and the steering column 300 can be separated from each other.

[0053] In this application, the "preset depth" refers to a depth alarm value pre-designated for the vehicle. If the current water depth detected by the water depth sensor is greater than or equal to the preset depth, it indicates that the vehicle has submerged beyond the safe range, and the doors may be trapped by the water and unable to open. If the current water depth detected by the water depth sensor is less than the preset depth, it indicates that the vehicle has not submerged in water, or the water depth is relatively shallow. At this point, personnel can manually determine the vehicle's environment and whether the doors can be opened normally. The preset depth can be flexibly designed based on actual conditions.

[0054] In addition, the connection of the steering wheel 100 to the steering column 300 through the locking mechanism 200 means that the locking mechanism 200 is a limiting structure between the steering wheel 100 and the steering column 300, and by switching the state of the locking mechanism 200, the locking or separation between the steering wheel 100 and the steering column 300 can be achieved. When the locking mechanism 200 is in the unlocked state, that is, when the locking mechanism 200 does not act, the steering wheel 100 can be easily pulled out of the steering column 300 by the personnel, and the connection between the steering wheel 100 and the steering column 300 is a pluggable connection mode. For example, a sliding groove and a sliding block can be arranged between the two to achieve the pluggable connection mode; or a plug-in buckle can be arranged between the two to achieve the pluggable connection mode, and the present application does not limit this. When the locking mechanism 200 is in the locked state, that is, when the locking mechanism 200 acts, the steering wheel 100 and the steering column 300 are in a fixed connection relationship, and the personnel can control the steering wheel 100 to steer without worrying about the steering wheel 100 falling off the steering column 300.

[0055] Preferably, when the locking mechanism 200 is in the unlocked state, the steering wheel 100 can still rotate relative to the steering column 300. In this way, the steering wheel 100 can be pulled out of the steering column 300, but it can still complete the steering function.

[0056] For example, as shown in Figure 2 and Figure 3 The locking mechanism 200 may, for example, include a motor 210 and an execution member 220 connected to the motor 210, and the execution member 220 can directly act on the steering wheel 100 and the steering column 300 to control the locking or separation between the steering wheel 100 and the steering column 300.

[0057] For example, as shown in Figure 3As shown, the embodiment of the invention uses the example of a block 221 as the actuator 220 and a slot 101 and a protrusion 301 as the pluggable connection between the steering wheel 100 and the steering column 300. The steering wheel 100 includes a steering wheel 110 and a connecting post 120 connected to the steering wheel 110. The connecting post 120 is provided with a protrusion 121. The steering column 300 includes a connecting groove 310 for engaging with the connecting post 120. The inner wall of the connecting groove 310 is provided with a slot 311 extending along the length of the connecting post 120. The locking mechanism 200 includes a motor 210 and a block 221 connected to the output end of the motor 210. When the connecting post 120 is inserted into the connecting groove 310, the motor 210 is controlled to drive the block 221, causing it to lock against the protrusion 121. At this point, the locking mechanism 200 is in a locked state. The steering wheel 100 and the steering column 300 are rotatable but fixedly connected axially. If the steering wheel 100 needs to be pulled out, the control motor 210 drives the clamping block 221 again, so that the clamping block 221 releases the protrusion 121. At this time, the locking mechanism 200 is in an unlocked state, and the steering wheel 100 and the steering column 300 can be axially separated from each other.

[0058] It should be noted that the above is an example description of the steering wheel 100 , the steering column 300 and the locking mechanism 200 , and this application does not impose any limitation thereto.

[0059] The vehicle steering wheel control method of the present application can determine the connection relationship between the steering wheel 100 and the steering column 300 based on the relationship between the current depth of the vehicle's entry into the water and the preset depth. Specifically, when the current depth of the vehicle's entry into the water detected is greater than or equal to the preset depth, it indicates that the vehicle's entry into the water is deep and the people inside the vehicle are in an extremely dangerous situation. At this time, the locking mechanism 200 is controlled to be in an unlocked state, so that the steering wheel 100 and the steering column 300 can be separated from each other. In this way, the people inside the vehicle can pull the steering wheel 100 out of the steering column 300 in time, and use the steering wheel 100 as a window-breaking tool to smash the car window, so that the people inside the vehicle can make an emergency escape from the car. This is conducive to improving the safety of people driving the vehicle.

[0060] It is easy to understand that the postures of vehicles when falling into water are diverse. If only the current water depth of the vehicle in a single direction is detected and compared with the preset depth, the judgment of the vehicle's water entry status may be inaccurate. Figure 4 As shown, the steps of obtaining the current water depth of the vehicle include:

[0061] Obtaining a first current water depth of the vehicle along a first direction;

[0062] Obtaining a second current water depth of the vehicle along a second direction;

[0063] Obtaining a third current water depth of the vehicle along a third direction, where the first direction, the second direction, and the third direction are perpendicular to each other;

[0064] The maximum value among the first current water immersion depth, the second current water immersion depth, and the third current water immersion depth is used as the current water immersion depth.

[0065] In this embodiment, the front-to-back direction of the vehicle is used as the first direction, the left-to-right direction of the vehicle is used as the second direction, and the height direction of the vehicle is used as the third direction. This embodiment can obtain the current water depth of the vehicle in three directions. Then, the water depths of the vehicle in the three directions are compared, and the maximum value of the water depths in the three directions is used as the current water depth of the vehicle. For example, if the first current water depth is greater than the second current water depth and the third current water depth, it indicates that the vehicle is deeply immersed in water in the front-to-back direction. At this time, it can be determined that the vehicle is immersed in water in the front or rear direction, and the current water depth of the vehicle is the first current water depth.

[0066] This allows accurate determination of the vehicle's direction of entry and its current depth in that direction. This current depth is then compared with a preset depth to determine the connection between the steering wheel 100 and the steering column 300. This reduces the likelihood of misjudging the vehicle's depth, preventing delays in occupants' escape opportunities and ultimately improving vehicle safety.

[0067] It should be noted that if the first current water entry depth, the second current water entry depth and the third current water entry depth are equal, then all three can be used as the current water entry depth; if two of the first current water entry depth, the second current water entry depth and the third current water entry depth are the same and are both greater than the remaining one, then the same two of the three can be used as the current water entry depth.

[0068] In some embodiments, the preset depth includes a first preset depth set along a first direction, a second preset depth set along a second direction, and a third preset depth set along a third direction. The step of determining the magnitude relationship between the current water entry depth and the preset depth includes:

[0069] Based on the current water depth, selecting one of the first preset depth, the second preset depth, and the third preset depth, with the setting direction being the same as the direction of the vehicle's current water depth as the preset depth;

[0070] Determine the relationship between the current water depth and the preset depth.

[0071] When a vehicle enters water, the first, second, and third current water depths are detected, and the maximum of the three is used as the vehicle's current water depth. Furthermore, the vehicle's entry direction can be determined based on the aforementioned magnitude relationship, e.g., whether the entry direction is the first, second, or third direction. It will be readily understood that the vehicle typically has different lengths in each direction. Therefore, when the vehicle enters the water from different directions, the degree of submergence of the vehicle will also vary.

[0072] Therefore, based on the above situation, this embodiment also divides the preset depth into multiple ones. Specifically, the preset depth includes a first preset depth set along the first direction, a second preset depth set along the second direction, and a third preset depth set along the third direction. Optionally, the values ​​of the first preset depth, the second preset depth, and the third preset depth may not be exactly the same, or may be completely different. After determining the current water depth of the vehicle, the one in the first preset depth, the second preset depth, and the third preset depth that is in the same direction as the current water depth of the vehicle can be selected as the preset depth. In this way, the current water depth of the vehicle and the preset depth can be compared based on the same direction, which is conducive to further improving the accuracy of judging the vehicle's water entry situation, further reducing the probability of misjudging the vehicle's water entry depth, avoiding delays in the escape time of people in the vehicle, and further helping to further improve the safety of people driving the vehicle.

[0073] In some embodiments, as Figure 2 and Figure 5 As shown, the steering wheel 100 is further provided with a first switch 130, and the first switch 130 is used to send a first signal. The method for controlling the vehicle steering wheel also includes:

[0074] If the current water depth is less than the preset depth and the first signal is not received, the locking mechanism 200 is controlled to be in a locked state so that the steering wheel 100 and the steering column 300 can be locked with each other.

[0075] In this embodiment, the first switch 130 can be an operating button provided on the steering wheel 100. By operating the first switch 130, the state of the locking mechanism 200 can also be controlled. If the current water immersion depth is less than the preset depth, it indicates that the vehicle's water immersion condition is within a controllable condition, or the vehicle has not fallen into the water. At this time, the people in the vehicle can operate the first switch 130 according to the actual situation encountered by the vehicle (for example, the vehicle encounters a dangerous situation and the door cannot be opened; or the vehicle is in normal condition and the door cannot be opened; or the vehicle is in normal condition and the door can be opened). When the first signal is not received, it indicates that the people in the vehicle do not need to unlock the steering wheel 100, so that the steering wheel 100 can complete the steering operation of the vehicle and avoid the situation where the steering wheel 100 accidentally falls off. In this way, it is beneficial to further improve the safety of people when driving.

[0076] In some embodiments, the vehicle steering wheel control method further includes:

[0077] If the current immersion depth is less than the preset depth and the first signal is received, determining the relationship between the duration of the first signal and the preset duration;

[0078] If the duration of the first signal is less than the preset duration, the locking mechanism 200 is controlled to be in a locked state.

[0079] In this embodiment, since the current depth of the vehicle submerged in water is less than the preset depth, it indicates that the vehicle's submergence is under control, or that the vehicle has not fallen into the water. In this way, the person inside the vehicle can operate the first switch 130 according to the actual situation, thereby controlling the connection state between the steering wheel 100 and the steering column 300. However, the first switch 130 is easily touched by a person by mistake. Therefore, this embodiment is also provided with an anti-accidental touch function. Specifically, if the duration of the first signal is less than the preset duration, it indicates that there is a possibility that the first switch 130 is touched by a person inside the vehicle by mistake, and the person inside the vehicle does not want the locking mechanism 200 to be unlocked. At this time, the locking mechanism 200 is controlled to be in a locked state. In this way, the accuracy of the determination of the person's intention can be improved, and the steering wheel 100 can be prevented from accidentally detaching from the steering column 300, thereby improving the safety of the person's driving.

[0080] In some embodiments, as Figure 5 As shown, the vehicle steering wheel control method further includes:

[0081] receiving a second signal from a torque sensor of the vehicle;

[0082] If the duration of the first signal is greater than or equal to the preset duration, and the second signal is greater than the preset torque, the locking mechanism 200 is controlled to be in a locked state.

[0083] In the embodiment, the state of the locking mechanism 200 is also controlled by the second signal of the torque sensor. The torque sensor can be an existing sensor on the vehicle, for example. When the duration of the first signal is greater than or equal to the preset duration, there is still a possibility that the first switch 130 is mistakenly touched by a person. Therefore, the second signal of the torque sensor is introduced in the embodiment to make a secondary determination. When the duration of the first signal is greater than or equal to the preset duration, and the second signal of the torque sensor is greater than a preset torque, it indicates that the person in the vehicle is still manually steering the steering wheel 100. In this case, it can be identified that the person in the vehicle does not want the steering wheel 100 to be detached from the steering column 300, thereby facilitating to further improve the accuracy of the determination of the intention of the person, to further reduce the probability of the condition that the steering wheel 100 is accidentally detached from the steering column 300 due to the mistaken touch of the first switch 130, and to further improve the safety of the driving of the person. Alternatively, the preset torque can be 1 Nm, 2 Nm, or the like, which can be flexibly set according to actual conditions.

[0084] In some embodiments, as shown in Figure 5 the control method of the vehicle steering wheel further includes:

[0085] If the duration of the first signal is greater than or equal to the preset duration, and the second signal is less than or equal to the preset torque, the locking mechanism 200 is controlled to be in the unlocked state.

[0086] In the embodiment, when the duration of the first signal is greater than or equal to the preset duration, and the second signal of the torque sensor is less than or equal to the preset torque, it indicates that the person in the vehicle wants to pull the steering wheel 100 out of the steering column 300 to perform a window breaking operation. In this way, it is beneficial to improve the accuracy of the determination of the intention of the person, to timely achieve the unlocking between the steering wheel 100 and the steering column 300, and to further improve the safety of the driving of the person.

[0087] In some embodiments, as shown in Figure 5 the control method of the vehicle steering wheel further includes:

[0088] If the duration of the first signal is greater than or equal to the preset duration, and no second signal is received, the locking mechanism 200 is controlled to be in the unlocked state.

[0089] In the embodiment, the torque sensor of the vehicle is usually electrically connected with the central controller of the vehicle. If no second signal is received, it means that the electrical connection between the torque sensor and the central controller of the vehicle is failed. In this case, it indicates that the central controller of the vehicle can be waterlogged and failed. Therefore, when the duration of the first signal meets the requirement, if no second signal is received, the locking mechanism 200 is directly controlled to be in the unlocked state, thereby timely achieving the unlocking between the steering wheel 100 and the steering column 300, and further improving the safety of the driving of the person.

[0090] In a second aspect, the present application provides a control device 10. As shown in Figure 6 The control device 10 comprises:

[0091] a memory 11 for storing executable program code;

[0092] a processor 12 for calling and running the executable program code from the memory 11, so that the control device 10 performs the control method as described in the first aspect.

[0093] For example, the control device 10 comprises one or more processors 12, which can support the control device 10 to implement the control method of the vehicle steering wheel in the method embodiments. The processor 12 can be a general-purpose processor or a special-purpose processor. For example, the processor can be a central processing unit (CPU), a digital signal processor (DSP), an application specific integrated circuit (ASIC), a field programmable gate array (FPGA), or other programmable logic devices, such as discrete gates, transistor logic, or discrete hardware components.

[0094] For example, the control device 10 can further comprise a communication unit to realize the input (reception) and output (transmission) of signals.

[0095] For example, the control device 10 can comprise one or more memories 11, which have executable program code stored thereon. The executable program code can be run by the processor 12 to generate instructions, so that the processor 12 performs the control method described in the above method embodiments according to the instructions.

[0096] For example, the processor 12 and the memory 11 can be separately arranged or integrated together, for example, integrated on a system on chip (SOC).

[0097] The control device 10 of the present application can implement the control method of the vehicle steering wheel as described in the first aspect, so that the person in the vehicle can timely pull out the steering wheel 100 from the steering column 300 and use the steering wheel 100 as a window breaking tool to break the window, so that the person in the vehicle can perform emergency escape from the vehicle. In this way, the safety of the person driving the vehicle can be improved.

[0098] In a third aspect, the present application provides a control system 1 of a vehicle steering wheel. As shown in Figure 2 and Figure 3As shown, the control system 1 of the vehicle steering wheel includes a steering column 300, a steering wheel 100, a locking mechanism 200, a water depth sensor 400 and a control device 10 as described in the second aspect. The steering wheel 100 is installed on the steering column 300 in a pluggable manner. The locking mechanism 200 is configured to put the steering wheel 100 and the steering column 300 in a locked state or an unlocked state. The water depth sensor 400 is used to detect the current water depth of the vehicle. The control device 10 is electrically connected to the locking mechanism 200 and the water depth sensor 400.

[0099] In this application, the vehicle steering wheel control system 1 can realize the connection or separation between the steering wheel 100 and the steering column 300. In the event of an emergency and the vehicle door cannot be opened, the occupant can promptly pull the steering wheel 100 from the steering column 300 and use it as a window-breaking tool to smash the window, allowing the occupant to escape from the vehicle. This helps improve the safety of the occupant when driving the vehicle.

[0100] In some embodiments, as Figure 2 As shown, the vehicle steering wheel control system 1 further includes a first switch 130, which is disposed on the steering wheel 100 and is configured to emit a first signal. The first switch 130 is electrically connected to the control device 10. In this embodiment, the provision of the first switch 130 improves the accuracy of determining a driver's intention and reduces the probability of the steering wheel 100 accidentally detaching from the steering column 300 due to an inadvertent activation of the first switch 130, thereby further improving driving safety.

[0101] Optionally, in some embodiments, a protective cover (not shown) is provided outside the first switch 130. In this way, the probability of a person accidentally touching the first switch 130 can be effectively reduced through physical protection.

[0102] Optionally, in some embodiments, the end of the connecting column 120 of the steering wheel 100 may be configured to be conical, thereby facilitating improving the efficiency and reliability of window breaking of the steering wheel 100 .

[0103] In a fourth aspect, the present application provides a vehicle comprising the vehicle steering wheel control system 1 described in the third aspect. The vehicle of the present application utilizes the vehicle steering wheel control system 1 described in the third aspect. When the vehicle encounters an emergency and the doors cannot be opened, occupants can promptly pull the steering wheel 100 from the steering column 300 and use it as a window-breaking tool to smash the windows, allowing occupants to escape from the vehicle.
