Description

Technical Field

[0001] This invention relates to the field of vehicle control technology, and more particularly to a vehicle control method, apparatus, electronic device, and computer-readable medium. Background Technology

[0002] The vehicle control method disclosed in CN118182613A proposes that when a malfunction is detected in the multimedia host, and the user cannot turn the vehicle control functions on or off via the virtual switch in the multimedia host, the corresponding control functions can be turned on or off via physical buttons on the steering wheel. For control switches of certain driving control functions related to vehicle driving safety, such as vehicle stability control, traction control, or automatic parking control switches, even if existing products from automakers include virtual switches in the multimedia host display, they tend to retain physical switches as well. The solution in CN118182613A, by retaining physical button switches, ensures the availability of switches when the multimedia host malfunctions, thereby ensuring functional safety.

[0003] However, the method of simultaneously using virtual switches and physical buttons to ensure the safety of driving control functions in case of multimedia head unit failure is not ideal in practical applications. Once users become familiar with and accustomed to one switching method, they may not be able to quickly recall and execute the other switching method in special situations (such as multimedia head unit failure). As a result, the backup physical button switch cannot be used in a timely manner to achieve the desired effect. Especially with the trend of automotive intelligence development, users can operate the virtual switches in the multimedia head unit through touch or more convenient, intuitive, and effortless voice interaction, making it easier to form a strong habitual memory of virtual switch operation. In special situations, it is even more difficult to immediately recall the location of the physical button switch and perform the relevant operation. Summary of the Invention

[0004] In view of this, embodiments of the present invention provide a vehicle control method, apparatus, electronic device, and computer-readable medium to solve the problem that when the display screen exhibits a fault state and is unable to respond to the operation of the virtual switch of the driving control function on the display screen by the driver or passenger, the driving control function cannot be switched to a state that is more conducive to vehicle driving safety in a timely manner.

[0008] The first state is a functional state corresponding to the display state of the virtual switch of the driving control function on the display screen, and the second state is a functional state opposite to the first state.

[0009] Optionally, before switching the driving control function's functional state from the first state to the second state, the method further includes:

[0010] Based on the fault status of the display screen and the functional status of the driving control function, determine whether to switch the functional status of the driving control function.

[0018] Optionally, the driving control function switching unit is used to simultaneously determine whether to switch the function state of the driving control function based on the fault status of the display screen and the function state of the driving control function.

[0022] The computing resources used by the display screen fault judgment module are independent of the computing resources used by the display screen monitoring module and the computing resources used by the display screen control unit for controlling the display screen.

[0029] One embodiment of the above invention has the following advantages or beneficial effects: The present invention provides a vehicle control method different from the prior art. When the display screen shows a fault state and cannot respond to the operation of the virtual switch of the driving control function on the display screen by the driver and passengers, the driving control function is automatically switched to a state that is more conducive to vehicle driving safety, so as to ensure the safety of vehicle driving when the display screen shows a fault state.

[0030] The further effects of the aforementioned unconventional alternative methods will be explained below in conjunction with specific implementation methods. Attached Figure Description

Obviously, the drawings described below are only some embodiments of the present invention. For those skilled in the art, other drawings can be obtained based on these drawings without creative effort. Wherein:

[0036] The following description, in conjunction with the accompanying drawings, illustrates exemplary embodiments of the present invention, including various details to aid understanding. These details should be considered merely exemplary. Therefore, those skilled in the art will recognize that various changes and modifications can be made to the embodiments described herein without departing from the scope and spirit of the invention. Similarly, for clarity and brevity, descriptions of well-known functions and structures are omitted in the following description.

[0037] It should be noted that the collection, analysis, use, transmission, and storage of user personal information involved in the technical solution of this invention all comply with relevant laws and regulations, are used for legitimate and reasonable purposes, and are not shared, disclosed, or sold outside of these legitimate uses, and are subject to supervision and management by regulatory authorities. Necessary measures should be taken to prevent unauthorized access to such personal information data, ensure that personnel authorized to access personal information data comply with relevant laws and regulations, and ensure the security of user personal information. Once this user personal information data is no longer needed, the risk should be minimized by restricting or even prohibiting data collection and / or deleting the data.

[0038] Figure 1 This is a flowchart of a vehicle control method according to an embodiment of the present invention. As an embodiment of the present invention, such as... Figure 1 As shown, the vehicle control method may include:

[0039] Step S101: Detect whether the display screen is in a fault state where it cannot respond to user operations; if yes, proceed to step S102; if no, end. It should be noted that ending means not executing or skipping other steps in this control flow, not that other control flows of the vehicle's driving control function completely stop. Through the detection in step S101, it can be determined whether the display screen is unable to respond to the driver's or passenger's operation of the virtual switch for the driving control function on the display screen due to a fault state. It should be noted that the display screen's fault state refers to all display screen operating states that may cause the display screen to be unable to respond to the driver's or passenger's operation of the virtual switch for the driving control function on the display screen. Unresponsiveness to user operations refers to, but is not limited to, the inability to respond to one or more of the user's interaction methods such as touch, voice recognition, gesture recognition, and / or gaze recognition on the target virtual switch.

[0040] In this step, the display screen fault detection unit detects whether the display screen is in a fault state where it cannot respond to user operations. If so, step S102 is executed; otherwise, the process ends. If the display screen is in a fault state where it cannot respond to user operations, it indicates that the user can no longer operate the virtual switch for the driving control function on the display screen. In order to ensure vehicle driving safety, step S102 is executed to reduce the safety risks of problems such as vehicle instability, loss of control, or collision.

[0041] Optionally, detecting whether the display screen is in a fault state where it cannot respond to user operations includes: receiving a monitoring signal for the display screen, and determining whether the display screen is in a fault state where it cannot respond to user operations based on the received monitoring signal. In embodiments of the present invention, the display screen monitoring module periodically sends a monitoring signal for the display screen to the display screen fault determination module, and the display screen fault determination module accurately determines whether the display screen is in a fault state where it cannot respond to user operations based on the received monitoring signal. For example, if the display screen fault determination module does not receive a monitoring signal within a preset n periods, it indicates that the display screen is in a fault state where it cannot respond to user operations, and then step S102 is executed. Alternatively, if the display screen fault determination module receives a monitoring signal indicating that the display screen is in a fault state where it cannot respond to user operations within a preset n periods, then step S102 is executed.

[0042] Step S102: Switch the driving control function's functional state from a first state to a second state; wherein the first state is the functional state corresponding to the display state of the virtual switch for the driving control function on the display screen, and the second state is the opposite of the first state. Optionally, the vehicle is in a drivable state before and after the state switch.

[0043] Optionally, before step S102, the vehicle control method further includes: determining whether to switch the functional state of the driving control function based on the fault state of the display screen and the functional state of the driving control function. In an example of the present invention, if it is detected that the display screen is in a fault state where it cannot respond to user operations, and the first state, which is the current functional state of the driving control function, is a functional state that is relatively likely to cause driving safety problems, then it is determined to switch the functional state of the driving control function, and then step S102 is executed to switch the functional state of the driving control function from the first state to the second state, so as to reduce the safety risks of problems such as vehicle instability, loss of control, or collision.

[0044] This invention provides a vehicle control method different from the prior art. When the display screen shows a fault state, making it impossible for the driver and passengers to operate the virtual switch of the driving control function on the display screen, the driving control function is automatically switched to a state that is more conducive to vehicle driving safety, so as to ensure the safety of vehicle driving when the display screen shows a fault state.

[0045] Optionally, in embodiments of the present invention, the driving control function is one or more of the following: vehicle driving stability control, steering control, braking force control, driving force control, and suspension control. In the method, when it is detected that the display screen is in a fault state where it cannot respond to user operation, and when it is detected that the first state is a driving control function disabled state, the driving control function's state is automatically switched from the first state to the second state. In an example of the present invention, the first state is a driving control function disabled state, and the second state is the opposite of the first state, a function enabled state. In this embodiment, the driving control function disabled state is a state in which the driving control function is relatively prone to causing driving safety problems.

[0046] Vehicle stability control (VSC) and traction control (RCD) are common active safety technologies, generally enabled by default to prevent skidding or wheel spin during driving. In specific scenarios, drivers may manually disable these functions. For example, when driving on a racetrack, drivers may not want VSC to intervene, preventing them from performing advanced techniques like sliding and drifting; similarly, when stuck in mud, snow, or sand, drivers may not want traction control to intervene, preventing them from fully utilizing wheel spin and prime mover power to extricate themselves. However, when VSC or traction control is disabled, and the virtual switch is inoperable due to a display malfunction, the following safety hazard arises: after completing a racetrack test or traction maneuver, the driver cannot operate the switch to restore the function to a safer state, potentially leading to skidding, instability, and / or wheel spin during subsequent driving. To address this technical problem, this invention proposes that if the display screen is detected to be in a fault state where it cannot respond to user operations, and the current functional state of the driving control function is a function-off state that is relatively likely to cause driving safety problems, then the functional state of the driving control function is switched from the function-off state to the function-on state to reduce the risk of vehicle driving safety problems.

[0047] Optionally, after step S102, the vehicle control method further includes: when the display screen is detected to have returned to a normal state that can respond to user operations, the display state of the virtual switch of the driving control function in the display screen is automatically switched to the display state corresponding to the second state of the driving control function, thereby avoiding the user's misunderstanding of the function state or incorrect operation of the switch due to the inconsistency between the function state of the driving control function and the display state of the virtual switch.

[0048] Figure 2 This is a flowchart of a vehicle control method according to a second embodiment of the present invention. As another embodiment of the present invention, such as... Figure 2 As shown, the vehicle control method may include:

[0049] Step S201: Detect whether the display screen is in a fault state where it cannot respond to user operations; if not, end.

[0050] Step S202: Detect whether the driving control function is in a disabled state; wherein the driving control function is one or more of the functions related to vehicle driving stability control, steering control, braking force control, driving force control, and suspension control. If not, the process ends.

[0051] If both the detection results of step S201 and step S202 are yes, then proceed to step S203. If either the detection result of step S201 or the detection result of step S202 is yes, then the process ends.

[0052] Step S203: Switch the driving control function from the function off state to the function on state.

[0053] The display screen fault detection unit detects whether the display screen is in a fault state where it cannot respond to user operations. If so, it indicates that the user can no longer operate the virtual switch for the driving control function on the display screen. If the driving control function is also detected to be in a disabled state, the unit switches the driving control function from the disabled state to the enabled state to reduce the safety risk of vehicle instability. Optionally, the vehicle is drivable before and after the state switch. In this embodiment, the disabled state of the driving control function is a state in which driving safety problems are relatively likely to occur.

[0054] It should be noted that, Figure 2 This is merely an illustrative embodiment of the present invention. The execution order of steps S201 and S202 is not limited. Step S201 can be executed first, followed by step S202; or step S202 can be executed first, followed by step S201; or steps S201 and S202 can be executed simultaneously. When the display screen is detected to be in a fault state where it cannot respond to user operations, and the driving control function is in a disabled state, the driving control function is switched from the disabled state to the enabled state.

[0055] In another embodiment of the present invention, the driving control function is an automatic parking function. The vehicle control method includes: when it is detected that the display screen is in a fault state where it cannot respond to user operation, and when it is detected that the first state is the driving control function's enabled state, the driving control function's function state is automatically switched from the first state to the second state. In this embodiment of the present invention, the first state corresponding to the display state of the virtual switch for the automatic parking function on the display screen is the enabled state, and the second state is the opposite of the first state, the disabled state. The user activates the automatic parking function by operating the virtual switch for the automatic parking function on the display screen. During the automatic parking process, if the user suddenly discovers that the vehicle may collide with surrounding obstacles, and if the display screen is in a fault state where it cannot respond to user operation, the user will not be able to deactivate the automatic parking function by operating the virtual switch to avoid continuing automatic parking and causing a collision. At this time, the enabled state of the automatic parking function is a function state that is relatively likely to cause driving safety problems. Therefore, the vehicle control method provided by this embodiment of the present invention can automatically switch the automatic parking function to the disabled state to avoid continuing automatic parking and causing a collision. In this embodiment, the enabled state of the driving control function is a function state that is relatively likely to cause driving safety problems.

[0056] Figure 3 This is a schematic diagram of the system architecture of a vehicle according to an embodiment of the present invention. Figure 3 As shown, the vehicle includes a display screen and a control device. The control device includes a display screen control unit, a display screen fault detection unit, a driving control function switching unit, and a driving control function unit.

[0057] A control device is a general term for related functional units or modules. The physical form of the control device includes all forms in the prior art that can achieve the purpose of this invention. The control device can be a single physical entity or it can be composed of multiple logically related physical entities that are distributed in a decentralized manner.

[0058] The display control unit is the control part that manages and controls the display screen through some means (such as programming, hardware connection, etc.). Specifically, it includes, but is not limited to, image processing, display management, screen switching, touch interaction processing, voice interaction processing, and input / output signal processing.

[0059] The display screen fault detection unit is used to detect whether the display screen is in a faulty state where it cannot respond to user operations. The display screen fault detection unit can implement the detection in any manner known in the prior art and generate relevant fault status information for use by other modules.

[0060] The driving control function unit is the part of the control device that implements driving control functions. Driving control functions refer to the functions of comprehensively and / or individually controlling the vehicle's driving actuators to achieve driving objectives. Driving objectives are various goals that the vehicle must achieve during driving, including but not limited to vehicle stability, collision safety, assisted driving, and / or automatic driving. Driving actuators are devices that convert the output of a power source (such as an internal combustion engine, electric motor, or other power system) into mechanical motion that drives the wheels, thereby enabling the vehicle to move forward, backward, stop, turn, or perform other movements. Driving actuators include, but are not limited to, one or more of the following: drive units, power transmission units, steering actuators, braking actuators, suspension systems, energy management devices, and / or auxiliary actuators.

[0061] The driving control function switching unit is a component that, under normal conditions, switches the functional state of the driving control function based on vehicle status information and / or user operation signal events to the virtual switch. In this invention, the driving control function switching unit can also switch the functional state of the driving control function from a first state to a second state when a fault state is detected in which the display screen cannot respond to user operation; wherein the first state is the functional state corresponding to the display state of the virtual switch for the driving control function on the display screen, and the second state is the functional state opposite to the first state. Optionally, the driving control function switching unit is used to determine whether to switch the functional state of the driving control function based on the fault state of the display screen and the functional state of the driving control function.

[0062] like Figure 4 As shown, in another embodiment of the present invention, the display screen fault detection unit includes a display screen monitoring module and a display screen fault judgment module. The display screen monitoring module is used to monitor the working status of the display screen and periodically send monitoring signals. The display screen fault judgment module is used to determine whether the display screen is in a fault state that cannot respond to user operations based on the received monitoring signals.

[0063] The display monitoring module monitors the operating status of the display screen and periodically sends monitoring signals for use by other parts or modules. The monitoring method can be any known method. For example, it can be implemented using a watchdog timer. The watchdog software or hardware periodically sends monitoring signals indicating whether the display screen is normal or faulty, depending on whether it receives a trigger signal from the display screen control unit indicating normal operation (i.e., whether it receives a "feed the watchdog" signal). These monitoring signals are the periodically sent monitoring signals by the display monitoring module. Specifically, when the display screen is working normally, the display screen control unit sends a trigger signal (i.e., "feed the watchdog") to the watchdog software or hardware, and the watchdog software or hardware outputs a corresponding periodic monitoring signal indicating normal operation. When the display screen malfunctions, the display screen control unit cannot send a trigger signal to the watchdog software or hardware, and the watchdog software or hardware outputs a corresponding periodic monitoring signal indicating a display screen malfunction or does not output a monitoring signal. It should be noted that not sending or outputting a signal should also be considered a signal whose meaning can be clearly defined by distinguishing it from signals that are sent or output.

[0064] The display screen fault diagnosis module is used to determine whether the display screen is in a faulty state, unable to respond to user operations, based on received monitoring signals. The judgment method of the display screen fault diagnosis module can be any known method. For example, if a monitoring signal indicating a display screen fault is continuously received within a set number of cycles, it is determined that the display screen has malfunctioned and is unable to respond to user operations. It should be noted that the monitoring signal indicating a display screen fault can be represented by a predefined, meaningful status code, a state where no monitoring signal is received, or a difference compared to the monitoring signals received during the normal operation cycle of the display screen.

[0065] Optionally, the computing resources used by the display screen fault diagnosis module are independent of those used by the display screen monitoring module and the display screen control unit used to control the display screen. When the display screen control unit experiences a crash, freeze, or other malfunction, this independent computing resource allocation allows the display screen fault diagnosis module to continue its judgment process independently and accurately. This ensures that the display screen fault diagnosis module can send display screen fault information to the driving control function switching unit, ultimately ensuring that the driving control function switching unit switches the driving control function to a state more conducive to vehicle driving safety when the display screen fails to respond to user operations. This independence of computing resources can be at the hardware level (such as processor, memory, and / or I / O devices) or at the software level (such as operating system, applications, and / or virtual machines).

[0066] In another aspect, the present invention also provides a computer-readable medium, which may be included in the device described in the above embodiments; or it may exist independently and not assembled into the device. The computer-readable medium carries one or more programs, and when the one or more programs are executed by the device, the device implements the following method: detecting whether the display screen is in a fault state where it cannot respond to user operations; when the display screen is detected to be in a fault state where it cannot respond to user operations, switching the functional state of the driving control function from a first state to a second state; wherein the first state is a functional state corresponding to the display state of the virtual switch of the driving control function on the display screen, and the second state is a functional state opposite to the first state.

[0067] In another aspect, embodiments of the present invention also provide a computer program product, including a computer program that, when executed by a processor, implements the methods described in any of the above embodiments.

[0068] When a display control unit malfunction prevents the driver and passengers from operating the virtual switch for the driving control function on the display screen, this embodiment of the invention can automatically switch the state of the driving control function to a state that is more conducive to vehicle driving safety, so as to ensure vehicle driving safety when the display screen shows a malfunction.

[0069] The specific embodiments described above do not constitute a limitation on the scope of protection of this invention. Those skilled in the art should understand that various modifications, combinations, sub-combinations, and substitutions can occur depending on design requirements and other factors. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of this invention should be included within the scope of protection of this invention.
