Description

Technical Field

[0001] This invention relates to the field of vehicle control technology, and in particular to a vehicle assistance method and vehicle for getting out of trouble. Background Technology

[0002] With the development of the automotive industry, more and more cars are entering the fields of production and daily life, providing great convenience for people's transportation. However, in rainy weather, when driving on muddy rural roads, vehicles are often prone to getting stuck in the mud, causing wheel slippage. At this time, most people will follow inertia and increase the throttle to increase the wheel speed in an attempt to get out of trouble. However, this operation often causes the ground attachments (mud, sand, etc.) that originally supported the weight and friction of the wheels to be thrown out, causing the wheels to sink deeper and deeper. At the same time, more mud and sand will adhere to the gaps in the wheels, resulting in a decrease in the coefficient of friction, which will actually exacerbate the difficulty of getting the vehicle out of trouble.

[0003] Therefore, a vehicle-assisted extrication method and vehicle are needed to solve the above-mentioned technical problems. Summary of the Invention

[0004] The purpose of this invention is to provide a vehicle assistance method and vehicle that can assist the driver in getting out of trouble, enabling the vehicle to get out of trouble as quickly as possible.

[0005] To achieve this objective, the present invention adopts the following technical solution:

[0006] A method for assisting a vehicle in getting out of trouble includes the following steps:

[0007] S1. Real-time monitoring of vehicle driving status;

[0008] S2. Determine if the vehicle is in a slippery state. If yes, proceed to the next step; otherwise, return to step S1.

[0009] S3. The driver determines the location of the vehicle's escape route and marks the location on the vehicle's control system.

[0010] S4. The control system prompts the driver to turn the steering wheel within a set angle range, and the driver controls the vehicle to reverse and move forward within a set distance until the vehicle moves to the position where it can get out of trouble.

[0011] S5. The control system controls the vehicle to travel at a set speed at a constant speed to complete the escape from the predicament.

[0012] Furthermore, in step S2, when the difference between the vehicle's driving speed and the speed of the drive wheels is within a set range, the vehicle is considered to be in a slipping state.

[0013] Furthermore, the rotational speed of the drive wheels is detected using speed sensors installed on the vehicle.

[0014] Furthermore, the set difference range can be calibrated.

[0015] Furthermore, an alarm system is installed in the driver's cab of the vehicle. The alarm system is connected to the control system and will alert the driver when the vehicle is determined to be in a skidding state.

[0016] Furthermore, the alarm system includes a voice broadcast system, a light prompt system, and / or a text prompt system.

[0017] Furthermore, in step S4, when the angle at which the driver turns the steering wheel is not within the set angle range, the control system alerts the driver through the alarm system.

[0018] Furthermore, in step S4, when the vehicle reverses to a set distance, the control system prompts the driver to brake through the alarm system.

[0019] Furthermore, in step S4, when the vehicle travels to a set distance, the control system prompts the driver to brake through the alarm system.

[0020] A vehicle includes a control system that uses the vehicle assistance method described above to assist the vehicle in getting out of trouble.

[0021] The beneficial effects of this invention are:

[0022] This invention provides a vehicle assisted extrication method that monitors the vehicle's status in real time. When the vehicle is determined to be slipping, the driver exits the vehicle to locate the extrication point. This location is then marked on the vehicle's control system. The control system plans and prompts the driver to turn the steering wheel within a set angle range and controls the vehicle to move backward and forward within a set distance until the vehicle reaches the extrication point. Finally, the control system maintains the vehicle at a set speed to complete the extrication. This method avoids the driver blindly operating based on inertia. By prompting and instructing the driver through the control system, it assists the driver in extricating the vehicle from the predicament as quickly as possible.

[0023] The present invention provides a vehicle including a control system, which employs the vehicle assisted extrication method described above to assist the vehicle in extricating itself from difficult situations. This assists the driver in extricating the vehicle from trouble, enabling it to do so as quickly as possible. Attached Figure Description

[0025] The technical solution of the present invention will be further described below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the invention and not intended to limit it. Furthermore, it should be noted that, for ease of description, only the parts relevant to the present invention are shown in the accompanying drawings, not all of them.

[0026] In the description of this invention, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "linking" should be interpreted broadly. For example, they can refer to fixed connections or detachable connections; mechanical connections or electrical connections; direct connections or indirect connections through an intermediate medium; and internal connections between two components. Those skilled in the art can understand the specific meaning of these terms in this invention based on the specific circumstances.

[0027] In this invention, unless otherwise explicitly specified and limited, "above" or "below" the second feature can include direct contact between the first and second features, or contact between the first and second features through another feature between them. Furthermore, "above," "over," and "on top" of the second feature includes the first feature directly above or diagonally above the second feature, or simply indicates that the first feature is at a higher horizontal level than the second feature. "Below," "below," and "under" the second feature includes the first feature directly below or diagonally below the second feature, or simply indicates that the first feature is at a lower horizontal level than the second feature.

[0028] When encountering rainy weather, vehicles often get stuck in muddy rural roads, causing wheel slippage. Most people instinctively increase the throttle to speed up the wheels and try to get out. However, this often causes the wheels to spin too fast, throwing off the ground debris (mud, sand, etc.) that was supporting the wheels' weight and friction, causing the wheels to sink even deeper. At the same time, more mud and sand accumulate in the wheel wells, reducing the coefficient of friction and actually making it harder to get out.

[0029] To address these issues, the vehicle's control system assists the driver in extricating the vehicle from trouble, enabling it to do so as quickly as possible. Figure 1 As shown, the present invention provides a vehicle assisted extrication method. The vehicle assisted extrication method includes the following steps:

[0030] S1. Real-time monitoring of vehicle driving status;

[0031] S2. Determine if the vehicle is in a slippery state. If yes, proceed to the next step; otherwise, return to step S1.

[0032] S3. The driver determines the location of the vehicle's escape route and marks the location on the vehicle's control system.

[0033] S4. The control system prompts the driver to turn the steering wheel within a set angle range. The driver controls the vehicle to move backward and forward within a set distance until the vehicle moves to the position to get out of trouble.

[0034] S5. The control system controls the vehicle to travel at a set speed at a constant speed to complete the extrication.

[0035] The above methods can prevent drivers from blindly operating based on inertia. By reminding and instructing the driver through the control system, the driver can be assisted in getting out of trouble, enabling the vehicle to get out of trouble as soon as possible.

[0036] Furthermore, in step S2, when the difference between the vehicle's travel speed and the speed corresponding to the drive wheel rotation speed is within a set difference range, the vehicle is considered to be in a slipping state. Since the vehicle's drive wheels determine its travel speed, when the difference between the vehicle's travel speed and the speed corresponding to the drive wheel rotation speed is within the set difference range, it is determined that the travel speed and the speed corresponding to the drive wheel rotation speed are severely mismatched, therefore, it can be determined that the vehicle is in a slipping state. In this embodiment, to improve the accuracy of the judgment, the set difference range is obtained through testing the vehicle in actual road conditions, and then the set difference range is calibrated. Moreover, different set difference range parameters can be manually calibrated according to different vehicle models.

[0037] Furthermore, speed sensors installed on the vehicle are used to detect the rotational speed of the drive wheels. These speed sensors can collect the rotational speed of the drive wheels in real time and transmit the data to the control system, allowing the control system to analyze whether the vehicle is slipping.

[0038] Furthermore, an alarm system is installed in the vehicle's cab. This alarm system is communicatively connected to the control system. When the vehicle is determined to be in a skidding state, the alarm system alerts the driver. Specifically, the alarm system can be a voice broadcast system, a light warning system, and / or a text warning system. By providing text, voice, or light warnings through the alarm system, the driver can promptly understand the vehicle's driving status and take appropriate actions based on whether the vehicle is skidding. In this embodiment, guidance text is played through a HUB (Head-Up Display) to alert the driver.

[0039] Furthermore, in step S4, when the driver turns the steering wheel at an angle outside the set angle range, the control system alerts the driver via an alarm system. Because drivers can easily turn the steering wheel according to their own intentions while driving, this can lead to over- or under-adjustment. By setting the angle range, the control system can provide real-time guidance to the driver, ensuring they can correctly operate the steering wheel. In this embodiment, data collected during the vehicle's traction test is stored in the control system to guide the driver in overcoming difficulties.

[0040] Furthermore, in step S4, when the vehicle reverses to a set distance, the control system prompts the driver to brake via an alarm system. This real-time alarm system guides the driver to maneuver the vehicle within a suitable distance, facilitating a quick adjustment to the extrication position and reducing the time required to escape the predicament.

[0041] Furthermore, in step S4, when the vehicle travels to the set distance, the control system prompts the driver to brake via an alarm system. This real-time alarm system guides the driver to maneuver the vehicle within a suitable distance, facilitating a quick adjustment to the extrication position and reducing the time required to escape the predicament.

[0042] In this embodiment, the set distance can be obtained through actual traction tests, thereby ensuring that the set distance can effectively guide actual vehicles to get out of trouble.

[0043] Furthermore, in this embodiment, the control system consists of a vehicle controller and an in-vehicle display screen. The driver can input the location of the vehicle to get out of trouble through the in-vehicle display screen, and the vehicle controller will match the stored data and patterns to guide the vehicle to get out of trouble.

[0044] A vehicle includes a control system that uses the vehicle assistance method described above to help the vehicle get out of trouble.

[0045] Obviously, the above embodiments of the present invention are merely examples for clearly illustrating the present invention, and are not intended to limit the implementation of the present invention. Those skilled in the art can make other variations or modifications based on the above description. It is neither necessary nor possible to exhaustively describe all embodiments here.
