DETAILED DESCRIPTION OF THE EMBODIMENTS

[0030] Now, various exemplary embodiments of the present disclosure will be described in detail with reference to the accompanying drawings. The description of the exemplary embodiments is merely illustrative and in no way limits the present disclosure and its application or use. The present disclosure can be implemented in many different forms and is not limited to the embodiments described herein. These embodiments are provided to make the present disclosure thorough and complete, and to fully convey the scope of the present disclosure to those skilled in the art. It should be noted that: unless otherwise specifically stated, the relative arrangements of components and steps, the components of materials, numerical expressions and values set forth in these embodiments should be construed as merely exemplary and not as limitations.

[0032] In this disclosure, when it is described that a specific component is located between a first component and a second component, there may or may not be an intermediate component between the specific component and the first component or the second component. When it is described that a specific component is connected to other components, the specific component may be directly connected to the other components without an intermediate component, or may not be directly connected to the other components and have an intermediate component.

[0033] All terms used in this disclosure (including technical terms or scientific terms) have the same meaning as understood by those of ordinary skill in the art to which this disclosure pertains, unless otherwise specifically defined. It should also be understood that terms defined in a general dictionary, for example, should be interpreted as having a meaning consistent with their meaning in the context of the relevant art, and should not be interpreted in an idealized or overly formal sense, unless specifically defined as such here.

[0034] Technologies, methods, and devices known to those of ordinary skill in the relevant art may not be discussed in detail, but where appropriate, the technologies, methods, and devices should be regarded as part of the specification.

[0035] The inventors found in the process of practice that if the existing automotive braking system is modified and a decoupling device is installed on the braking system, the master cylinder and the brake can be decoupled, so that the vehicle enters the game mode. If not decoupled, since the engine does not start in the parked state, the vacuum booster will cause the brake pedal to be unable to be depressed due to lack of vacuum, and the pedal displacement sensor will not be able to output a signal, and the vehicle's brake pedal cannot be used as a game pedal simulator. Figure 1Shown is the structure of a common automotive braking system in the prior art, including a brake pedal 1, a power assist device 2, a master cylinder 3, a hydraulic control valve 4, front brakes 5, rear brakes 6, a brake fluid container 7, a vacuum pump 8, a vacuum tank 9, and a brake hose 10. The power assist device 2 includes a vacuum booster. The master cylinder 3 serves as the brake master cylinder. The hydraulic control valve 4 includes various control valves. The front brakes 5 and the rear brakes 6 include wheel cylinders. The brake fluid container 7 includes an oil reservoir cup. The brake hose 10 is made of synthetic rubber. After the driver operates the brake pedal 1, high-pressure brake fluid is generated through the power assist device 2 and the master cylinder 3, and is transmitted through the brake hose 10 to the brakes of the four wheels (front brakes 5 and rear brakes 6) for vehicle braking. When the power assist device 2 (vacuum booster) fails, only manual force can be used to push the master cylinder 3. Since only manual force can build a pressure of 2 - 3 mpa, the piston stroke of the master cylinder 3 is very short. Therefore, the displacement sensor of the pedal cannot be used as a game simulator after the assist fails.

[0036] The prior art solution uses a decoupled electronic booster. When the vehicle is powered on, the brake pedal can still be normally depressed, and the pedal displacement sensor can still output a voltage signal for use in game manipulation control. Due to the limited stroke of the booster decoupling structure, if the displacement sensor is to have an output signal, the vehicle must be in a powered-on state, and the booster motor still operates during the depression process, resulting in a large power consumption. Moreover, the brake cylinder still moves every time the brake is depressed, accelerating the wear and tear of the brakes.

[0037] As Figure 2 and Figure 3 As shown, the vehicle game simulator provided in this embodiment includes: a decoupling device connected to the brake master cylinder 15. The decoupling device includes a motor 11, a lead screw 13, and a piston 14 arranged in sequence. The piston 14 is connected to the brake master cylinder 15. The brake master cylinder 15 contains brake fluid inside. The piston 14 is provided with a liquid outlet hole 16 on the side close to the brake master cylinder 15 to communicate the piston 14 with the brake master cylinder 15. A lead screw nut 12 that mates with the lead screw 13 is arranged on the lead screw 13. The motor 11 is used to drive the lead screw nut 12 to rotate. In the normal driving state, the piston 14 is fixed through the lead screw nut 12. In the game mode, the motor 11 is used to drive the lead screw nut 12 to rotate, thereby driving the lead screw 13 and the piston 14 to move in the direction of the motor 11, and the brake fluid in the brake master cylinder 15 enters the piston 14 through the liquid outlet hole 16.

[0038] Wherein, the lead screw nut 12 is arranged between the motor 11 and the lead screw 13.

[0039] Further, the vehicle game simulator further includes a brake pedal connected to the brake master cylinder 15.

[0040] During operation, under normal driving conditions, the piston 14 is fixed by the lead screw nut 12. In this state, the working mode of the master cylinder is the same as that of a traditional master cylinder. Due to the self-locking property of the lead screw nut 12, even when the motor 11 is not powered, the piston 14 of the decoupling device can still be maintained at its current position, ensuring the safety of braking. When it is necessary to enter the game mode, the motor 11 drives the lead screw nut 12 to rotate, driving the lead screw 13 and the piston 14 to move towards the motor 11. The brake fluid in the brake master cylinder 15 can enter the piston 14 through the liquid outlet hole 16 at the bottom of the piston 14, enabling a large pedal stroke to be achieved even in the absence of vacuum, which is used for the game simulator.

[0041] After starting the game mode, when the driver steps on the brake pedal, the brake fluid in the brake master cylinder 15 can enter the decoupling device through the liquid outlet hole 16 at the bottom of the piston 14. The feel of the brake pedal is achieved through the internal spring of the brake master cylinder 15 and the internal spring of the decoupling device, thus simulating a real braking feeling.

[0042] Furthermore, the decoupling device is arranged at the rear end of the brake master cylinder 15. Specifically, in some embodiments of the present invention, the decoupling device is arranged in the front chamber and / or the rear chamber of the master cylinder of the brake master cylinder 15. Preferably, the front chamber and the rear chamber of the master cylinder of the brake master cylinder 15 are simultaneously connected to two independent liquid storage chambers through the pipelines in the cylinder body of the brake master cylinder 15, which can achieve a greater stroke and complete decoupling.

[0043] As Figure 3 shown, in some embodiments of the present invention, the decoupling device is connected to the brake pipeline through a three-way joint. It should be noted that the present invention does not specifically limit the installation position of the decoupling device.

[0044] The vehicle game simulator provided by the embodiment of the present invention adopts the structure of a lead screw nut type decoupling master cylinder, and can conveniently enter and exit the game mode through motor control, and can control at any time whether to enter the game mode. The reliability in the non-game mode is no different from that of a traditional master cylinder; after entering the game mode, the master cylinder part no longer consumes energy, effectively saving energy; most of the structures can use the existing master cylinder components, and the development cost is relatively low.

[0045] As Figure 4 shown, during the actual execution process of the control method of the vehicle game simulator provided by this embodiment, it specifically includes:

[0046] Step S1, obtaining the current game mode control signal.

[0047] Step S2, judging whether the current game mode state is the power-on state according to the current game mode control signal.

[0048] Step S3: If so, control the motor 11 to contract the lead screw nut 12, so that the brake fluid can enter the decoupling device.

[0049] Specifically, drive the lead screw nut 12 to rotate through the motor 11; under the rotation of the lead screw nut 12, drive the lead screw 13 and the piston 14 to move towards the motor 11, so that the brake fluid in the master cylinder 15 enters the piston 14 through the liquid outlet hole 16.

[0050] Step S4: If not, control the motor 11 to open the lead screw nut 12, so that the brake fluid cannot enter the decoupling device.

[0051] Specifically, the piston 14 is fixed through the lead screw nut 12, and the brake fluid in the master cylinder 15 enters the piston 14 through the liquid outlet hole 16.

[0052] The control method of the vehicle game simulator provided by the embodiment of the present invention adopts the structure of a lead screw nut type decoupling master cylinder, and can conveniently enter and exit the game mode through motor control, and can control whether to enter the game mode at any time. The reliability in the non-game mode is no different from that of the traditional master cylinder; after entering the game mode, the master cylinder part no longer consumes energy, effectively saving energy; most of the structures can use the existing master cylinder components, and the development cost is relatively low.
