Thus, a feature defined as "first" or "second" may explicitly or implicitly include at least one such feature. In addition, technical solutions between the various embodiments can be combined with each other, but must be realized by a person skilled in the art, and when the technical solutions are contradictory or cannot be realized, the combination of the technical solutions should be considered to be absent and not be within the protection scope of the present invention.

Fig. 1 is a flowchart of a control method for a vehicle according to an embodiment of the present invention. Fig. 2 is a schematic structural diagram of a decoupled steering system according to an embodiment of the present invention. As shown in fig. 1 and 2, an embodiment of the present invention provides a control method for an automobile that may include a steering wheel assembly 1, a steering machine 3, and a clutch device 2 for connecting the steering wheel assembly 1 and the steering machine 3, the control method may include:

step S11, the operating mode of the vehicle is detected.

And step S12, decoupling the clutch device under the condition that the automobile is detected to enter the preset mode. The preset mode can be a game mode, an entertainment mode or a simulated driving mode.

Therefore, the clutch device is arranged between the steering wheel assembly and the steering machine, so that the connection between the steering wheel assembly and the steering machine can be disconnected through the decoupling clutch device under the condition that the automobile enters a preset mode, a user can play entertainment activities such as games through controlling the steering wheel, and the game sense of reality is strong. The automobile function is enriched, and meanwhile, potential safety hazards cannot be generated.

Specifically, the steering system of the automobile may include a steering wheel assembly 1 and a steering engine 3, the steering wheel assembly 1 being used for driver control of the automobile steering. The steering gear 3 is used to appropriately convert the steering torque and the steering angle from the steering wheel assembly 1 and output the converted torque to the steering link mechanism, thereby steering the vehicle. In order to enable a user to play games, simulate driving, etc. using the steering wheel assembly 1 for a more realistic game experience or simulated driving experience, the steering system of the car may further comprise a clutch device 2 arranged between the steering wheel assembly 1 and the steering gear 3. Connecting the steering wheel assembly 1 with the steering machine 3 under the condition that the clutch device 2 is coupled, wherein a user can control the steering machine 3 through the steering wheel assembly 1; with the clutch device 2 decoupled, the connection between the steering wheel assembly 1 and the steering gear 3 is broken, and the action of the steering wheel assembly 1 has no effect on the steering gear 3. The steering wheel assembly 1 may comprise a steering wheel 11 and a steering column 12, and the clutch device 2 may be located between the steering column 12 and the steering gear 3. The clutch device 2 may be an electromagnetic clutch, a friction clutch, a hydraulic clutch, or the like.

For example, the preset mode may be a game mode, and the car may include two operation modes, a driving mode and a game mode. In the driving mode, the clutch device 2 may be controlled to be in a coupled state to connect the steering column 12 with the steering engine 3, and the steering wheel 11 may control the steering engine 3 so that the user may normally perform a steering operation of the vehicle. Under the game mode, can control clutch 2 and be in the decoupling zero state to the disconnection steering column 12 with turn to the machine 3 between be connected, thereby the user can use steering wheel 11 to carry out amusement activities such as recreation, with the interdynamic and the authenticity of amusement activities such as reinforcing recreation, make the user produce the amusement experience of being personally on the spot, and can not arouse the safety problem.

In an alternative embodiment of the invention, the operating state of the vehicle can be detected before the decoupling of the clutch device 2, and the decoupling of the clutch device 2 can be rejected if the vehicle is in a driving state. Furthermore, it is also possible to detect whether the vehicle is in the parked state before the decoupling of the clutch device 2 and to reject the decoupling of the clutch device 2 if the vehicle is not in the parked state.

Specifically, as shown in fig. 3, taking the preset mode as the game mode as an example, when the user controls the vehicle to enter the game mode, the control device (e.g., the vehicle controller) of the vehicle may send a decoupling signal to the clutch device 2. After the clutch device 2 receives the decoupling signal, whether the automobile is in a running state is checked, if the automobile is in the running state, the decoupling signal is ignored and a prompt is sent to remind a user that the user cannot enter a game mode in the running state. If the vehicle is not in a driving state, it is continuously checked whether the vehicle is in a parking state. And if the automobile is not in the parking state, ignoring the decoupling signal and reminding a user that the game mode cannot be entered in the non-parking state. If the vehicle is in the parked state, the clutch device 2 is disengaged. That is to say, clutch 2 is when the car is gone the in-process and when not parking, all can not the decoupling zero to can avoid clutch 2 because user's maloperation unexpected decoupling zero when the car is gone the in-process or not parking, and then avoid accident's emergence.

As an alternative embodiment of the present invention, the control method for a vehicle may further include: and in the case that the automobile is detected to enter the preset mode, forbidding starting the automobile and/or forbidding exiting from the parking state.

Specifically, taking the preset mode as the game mode as an example, in the embodiment, the user can control the automobile to freely switch between the game mode and the driving mode. When the automobile is in a game mode, the starting of the automobile and/or the quitting of the parking state can be forbidden by cutting off the functions of a starting button and/or a parking brake (such as an electronic handbrake), so that the safety problems of sudden starting of the automobile and the like caused by misoperation in the process of entertainment activities such as game and the like of a user are avoided. In addition, when the automobile is in a game mode, the original light and entertainment multimedia systems of the automobile can be used, so that in the game mode, the maximum reality of an entertainment scene can be met by combining a plurality of functional components such as a steering wheel, a brake pedal and light, and a user can experience entertainment activities such as games personally on the scene.

In an alternative embodiment of the present invention, the control method for a vehicle may further include: before the automobile is allowed to run, the working mode of the automobile is detected, and under the condition that the automobile is in the preset mode, a user is prompted to exit the preset mode. After the automobile is determined to exit the preset mode, the automobile detects the state of the clutch device, and controls the clutch device to be coupled under the condition that the clutch device is in the decoupling state. Further, after determining that the clutch is coupled, the vehicle detects whether the clutch is locked, and controls the clutch to be locked if the clutch is unlocked, and allows the vehicle to run if the clutch is locked.

Specifically, as shown in fig. 4, taking the preset mode as the game mode as an example, when the user controls the automobile to start, in the checking stage before the automobile starts to prepare for driving, whether the automobile is in the game mode, whether the clutch device 2 is coupled, and whether the locking mechanism is locked after the clutch device 2 is coupled are checked in sequence, and if it is determined that the automobile is in the game mode, a reminding signal is sent to the user to remind the user that the automobile is currently in the game mode, and the user is prompted to start after needing to quit the game mode. After determining that the user exits the game mode, the automobile detects whether the clutch device 2 is coupled, and if the clutch device 2 is determined to be uncoupled, an alarm signal is sent to the user to alarm the user that the clutch device 2 is uncoupled, and the clutch device 2 is controlled to be coupled. After the clutch device 2 is coupled, whether the clutch device 2 is locked is detected, if the locking mechanism of the clutch device 2 is determined to be unlocked, a reminding signal is sent to a user to remind the user that the locking mechanism is unlocked, and the locking mechanism is controlled to be locked. If it is determined that the vehicle is not in the play mode and the clutch device 2 is coupled and locked, the vehicle is allowed to run.

Wherein, in the game mode, it is possible to detect whether the game mode exits, and in the case of detecting the exit from the game mode, detect the first rotation angle of the steering column 12 and the second rotation angle of the steering wheel of the automobile, and control the steering wheel 11 to rotate according to the detected first rotation angle and second rotation angle, so that the angle of the steering column 12 matches the angle of the steering gear 3.

Specifically, the operating mode of the automobile can comprise a game mode and a driving mode, and when a user needs to play entertainment activities such as games, the automobile can be controlled to enter the game mode. After exiting the play mode, the car automatically reverts to the drive mode. In the game mode, the user can play an entertainment event such as a game using the steering wheel 11. Therefore, when the game mode is exited, there is a possibility that an angular deviation may occur between the steering column 12 controlled by the steering wheel 11 and the steering gear 3, and the clutch device 2 may not be coupled or the steering wheel 11 may not be able to control the steering gear 3 correctly after the clutch device 2 is coupled. Therefore, in the present embodiment, if it is detected that the automobile exits the play mode in the play mode, the angles of the steering column 12 and the steered wheels of the automobile are detected. Since the first turning angle of the steering column 12 is related to the angle of the steering wheel 11, the second turning angle of the steered wheels of the car is related to the angle of the steering gear 3. Therefore, after the first rotation angle of the steering column 12 and the second rotation angle of the steering wheel are detected, the steering wheel can be controlled to rotate according to the first rotation angle and the second rotation angle so as to adjust the angle of the steering column 12, so that the angle of the steering column 12 is matched with the angle of the steering engine 3, and the clutch device 2 can be coupled smoothly. In this manner, the clutch device 2 can be smoothly coupled by matching the angle of the steering column 12 with the angle of the steering gear 3 each time the play mode is exited. In addition, after exiting the game mode, the automobile will gradually check whether the functions of the clutch device 2, the accelerator, the parking brake and other related components are recovered, so as to ensure that all the functions can be normally used after the automobile recovers to the driving mode.

In an alternative embodiment of the present invention, the control method for a vehicle may further include: and under the condition that the automobile is in a running state, detecting whether the clutch device 2 is decoupled, and under the condition that the clutch device 2 is decoupled, starting a driving auxiliary system and/or an automatic driving system of the automobile to control the automobile to stop at the side. Further, when the decoupling of the clutch device is detected, the clutch device 2 can be controlled to be coupled in an attempt, when the clutch device 2 is not coupled after the preset times of attempts, a user is reminded to overhaul and the automobile is forbidden to run again after parking, and when the clutch device 2 is coupled within the preset times of attempts, the speed of the automobile is limited.

Specifically, the embodiment discloses a control method for abnormal decoupling of a steering system in the running process of an automobile. As shown in fig. 5, when the vehicle is in a driving state, if it is detected that the clutch device 2 is abnormally decoupled, the vehicle controller of the vehicle may first send a warning message to a user, turn on the double-flashing and right-turning warning light to remind other vehicles on the road of paying attention to safety, and then determine the lane where the vehicle is located through the driving assistance system and/or the automatic driving system. In the case that the vehicle is not in the rightmost lane, the vehicle may be controlled to change lane to the right by the driving assistance system and/or the automatic driving system, and in the case that the vehicle is in the rightmost lane, the vehicle may be controlled to stop alongside. During the process of parking the vehicle alongside, the vehicle attempts to control the coupling device 2 for coupling. If the clutch device 2 cannot be coupled after a preset number of attempts (e.g., 3), the user is alerted to service immediately and the vehicle is prohibited from traveling again after the stop. If the clutch device 2 can be successfully coupled within the preset times of trial, the user is reminded to overhaul as soon as possible, and measures such as speed limitation are taken according to the road condition when the automobile runs again.

As shown in fig. 6, in an embodiment of the present invention, the preset mode may be, for example, a game mode, and the user may control the car to enter the game mode and exit the game mode. The process of entering the game mode is shown in the left part of fig. 6, the automobile is in the driving mode in a normal state, and when a user needs to play an entertainment activity such as a game, the automobile needs to be switched from the driving mode to the game mode. To do this, the user first needs to park and then applies to the car for entering the play mode, for example, to shift the gear selector into the G gear (i.e. play mode). At the moment, the automobile can check whether the parking is successful, if the parking is not successful, a warning is given to remind a user of checking the parking condition, and the user is reminded of parking again. If the parking is successful, the automobile can cut off and inhibit functions such as a hand brake and a start button, and therefore sudden starting of the automobile due to misoperation in the subsequent entertainment activities such as games is avoided. Subsequently, the entertainment system of the automobile can be connected with the electronic shift handle, the throttle, the air conditioner, the lighting, the entertainment multimedia system and the like, and simultaneously the steering wheel 11 is controlled to return to the right, and the initial rotation angle of the steering wheel 11 at the moment can be recorded by the angle sensor. The vehicle control system then triggers an instruction to decouple the clutch 2 to be in the disengaged state, at which point the mechanical connection between the steering column 12 and the steering engine 3 is fully disengaged, the vehicle enters the play mode and the user can begin entertainment activities such as games.

The process of exiting the game mode is shown in the right part of fig. 6, when exiting the game mode, the rotation angle of the steering wheel and the swing angle of the steering wheel can be respectively recorded through two angle sensors, the calculation is carried out through a traveling computer to determine the angle deviation between the steering column 12 and the steering wheel, and the steering wheel 11 is driven to rotate through the rotation assisting motor according to the angle deviation and the initial angle of the steering wheel, so that the angles of the steering column 12 and the steering wheel 3 at the two ends of the clutch device 2 are consistent. The vehicle may then be requested to exit the play mode and the clutch device 2 will be coupled after the angle matching is completed to connect the steering column 12 to the steering engine 3. The car will check whether the coupling was successful. If the coupling is not successful, a warning is given to the user to remind the user, and the clutch device 2 is controlled to be coupled again; if the coupling is successful, the automobile releases the cut-off inhibition of functions such as parking braking, a start button and the like, and releases the control of systems such as an accelerator pedal, a hand brake, illumination, an air conditioner and the like by an entertainment system. Subsequently, the automobile checks whether the functions of the systems such as the accelerator pedal, the handbrake, the lighting system, the air conditioner and the like are recovered, and if the functions are not recovered, the automobile gives a warning to remind a user to perform treatment. Finally, the automobile also checks whether the G gear of the gear shifter releases the cut-off inhibition of the parking brake, and if not, a warning is sent to remind a user; if the automobile is released, the automobile exits the G gear and is switched to a driving mode.

Embodiments of the present invention also provide a control device for a vehicle, which may be used to execute the control method for a vehicle described above. The control device may include, for example, a vehicle controller of an automobile.

As shown in fig. 7, the embodiment of the present invention also provides an automobile, and the automobile 100 may include a steering system and a control device 4, and the steering system may include a steering wheel assembly 1, a steering gear 3, and a clutch device 2. In this case, the clutch device 2 is used to connect the steering wheel assembly 1 to the steering gear 3, and the control device 4 is used to carry out the above-described control method for a motor vehicle.

Accordingly, embodiments of the present invention also provide a machine-readable storage medium having stored thereon instructions for enabling a processor to execute the above-described control method for an automobile when the instructions are executed by the processor.

The technical scheme of the invention provides the automobile capable of carrying out entertainment activities such as simulated driving games, simulated driving training and the like, and provides safety guarantee for the automobile in a driving mode, a preset mode (such as a game mode, an entertainment mode or a simulated driving mode and the like) and switching between the driving mode and the preset mode through a corresponding control strategy. By setting protection strategies of the automobile in various scenes such as before driving, during driving, after an abnormal decoupling accident and the like and matching with a driving auxiliary system and/or an automatic driving system of the automobile, the safety control of the automobile with a steering system decoupling function can be carried out to the maximum extent.
