Description

Technical Field

[0001] The present invention belongs to the technical field of automobile tire repair, and in particular relates to a tire inspection mode control method and system. Background Art

[0002] The statements in this section merely provide background information related to the present invention and do not necessarily constitute prior art.

[0003] Under the existing technical background, vehicles often encounter foreign objects such as stones and nails stuck in tires, and the driver needs to get off the vehicle for a visual inspection. At this time, there will always be a part of the tire position that is in contact with the ground and cannot be observed. The driver needs to drive the vehicle again and move it a certain distance before getting off the vehicle for observation, or two people are required to cooperate in the operation to achieve observation, which is very inconvenient. Summary of the Invention

[0004] To address the aforementioned issues, the present invention proposes a tire inspection mode control method and system, suitable for vehicles supporting autonomous driving technology. This system cleverly utilizes autonomous driving technology to automatically slow the vehicle's movement, allowing the driver to visually observe the tire's surroundings for foreign objects, simplifying the inspection process and ensuring safety.

[0005] According to some embodiments, the present invention adopts the following technical solutions:

[0006] A tire inspection mode control method comprises the following steps:

[0007] Get tire inspection control instructions;

[0008] Determine the vehicle's operating torque and calculate the number of revolutions required by the vehicle's powertrain;

[0009] Control the vehicle to enter the automatic driving mode, and control the vehicle to run in a predetermined direction with the operating torque until the required number of rotations is met or a certain resistance is encountered;

[0010] Control the vehicle to stop and exit the autonomous driving mode.

[0011] Through the above settings, the automatic driving technology is cleverly utilized, so that inspectors can get off the vehicle to inspect on their own. During the whole process, the vehicle is in a low-speed running state, so that inspectors can observe the specific condition of the wheels.

[0012] As an optional implementation, the specific process of determining the vehicle running torque includes setting the vehicle running speed, the running speed being lower than a predetermined threshold, and calculating the minimum torque for moving the vehicle based on the running speed, which is the vehicle running torque.

[0013] The predetermined threshold is determined based on road conditions, ambient lighting, vehicle conditions and vehicle parameters.

[0014] As an optional embodiment, the specific process of calculating the number of revolutions required by the vehicle power system includes determining a minimum threshold time based on an average time for inspecting all tires of the target vehicle, the minimum threshold time being greater than the average time, and calculating the number of revolutions required for the power system to run for at least the minimum threshold time based on vehicle tire parameters and power system parameters.

[0015] As an alternative embodiment, the resistance encountered is greater than the operating torque.

[0016] Through such a setting, on the one hand, if the inspector has already checked all tires in advance, artificial resistance can be applied to end the inspection process in advance and improve inspection efficiency; on the other hand, if the vehicle encounters an obstacle or emergency during driving, the vehicle can be stopped in time, the process can be stopped, and the safety of the vehicle and personnel can be ensured.

[0017] As an optional embodiment, the predetermined direction includes forward and backward.

[0018] The vehicle can be in reverse or forward driving state, which makes it convenient to determine the specific running direction according to the specific detection environment.

[0019] A tire inspection mode control system comprising:

[0020] a signal switch configured to obtain a tire check control instruction;

[0021] a calculation module configured to determine the vehicle operating torque and calculate the number of revolutions required by the vehicle power system;

[0022] a drive module configured to control the vehicle to enter an automatic driving mode and control the vehicle to move in a predetermined direction with an operating torque until the required number of rotations is met or a certain resistance is encountered;

[0023] The brake module is configured to control the vehicle to stop and exit the autonomous driving mode.

[0024] As an optional implementation, the signal switch is connected to the drive module and the brake module.

[0025] As an optional implementation, the brake module is connected to the power system and the electronic gear shifting system.

[0026] As an optional embodiment, the drive module is connected to the power system and the electronic gear shifting system.

[0027] A terminal device includes a processor and a computer-readable storage medium, wherein the processor is used to implement various instructions; the computer-readable storage medium is used to store multiple instructions, and the instructions are suitable for being loaded by the processor and executing the steps in the described method.

[0028] Compared with the prior art, the present invention has the following beneficial effects:

[0029] The present invention can facilitate the driver to intuitively observe the foreign objects around the entire tire, and the driver can directly check the foreign objects around the tire without having to repeatedly get on and off the vehicle to move the vehicle, thereby improving the convenience of foreign object inspection; at the same time, in this state, the vehicle control power is small, and a slight resistance can stop the vehicle, and the vehicle moves very slowly, without any safety risks.

[0030] The present invention can match and calculate the vehicle operating torque according to the vehicle model to be detected, road conditions, etc., and calculate the number of revolutions required by the vehicle power system, and has a certain degree of adaptability.

[0031] The present invention can artificially apply resistance after the inspector has already inspected each tire in advance to end the inspection process in advance, thereby improving inspection efficiency; and if the vehicle encounters an obstacle or an emergency during driving, the vehicle can be stopped in time, stopping the process and ensuring the safety of the vehicle and personnel.

[0035] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0036] It should be noted that the following detailed descriptions are illustrative and intended to provide further explanation of the present invention. Unless otherwise specified, all technical and scientific terms used herein have the same meaning as commonly understood by those skilled in the art to which the present invention belongs.

[0037] It should be noted that the terms used herein are only for describing specific embodiments and are not intended to limit the exemplary embodiments according to the present invention. As used herein, unless the context clearly indicates otherwise, the singular form is intended to include the plural form. In addition, it should be understood that when the terms "comprise" and / or "include" are used in this specification, they indicate the presence of features, steps, operations, devices, components and / or combinations thereof.

[0038] Example 1

[0039] In order to solve the problems in the prior art, the present invention provides a tire inspection mode control method, which can use the tire inspection mode signal switch to enter the tire inspection mode, so that the foreign matter around the tire can be directly checked without having to repeatedly get on and off the vehicle to move the vehicle. At the same time, in this state, the vehicle control power is small, and a slight resistance can stop the vehicle. The vehicle moves very slowly, and there is no safety risk.

[0040] Of course, the present invention is applicable to vehicles that support autonomous driving mode.

[0041] Specific as Figure 1 As shown, a tire inspection mode control method includes the following steps:

[0042] Get tire inspection control instructions;

[0043] Determine the vehicle's operating torque and calculate the number of revolutions required by the vehicle's powertrain;

[0044] Control the vehicle to enter the automatic driving mode, and control the vehicle to run in a predetermined direction with the operating torque until the required number of rotations is met or a certain resistance is encountered;

[0045] Control the vehicle to stop and exit the autonomous driving mode.

[0046] As a typical embodiment, the specific process of determining the vehicle running torque includes setting the vehicle running speed, the running speed being lower than a predetermined threshold, and calculating the minimum torque for moving the vehicle based on the running speed, which is the vehicle running torque.

[0047] In a typical embodiment, the predetermined threshold is determined based on road conditions, ambient lighting, vehicle condition, and vehicle parameters. For example, during daytime, when the lighting is good, the road is relatively smooth, and there are no obvious obstacles, the predetermined threshold can be set higher. This means that the vehicle can run slightly faster while still ensuring safety and ensuring that inspectors can clearly see the tire condition. Conversely, in poor lighting conditions or other circumstances, the predetermined threshold may need to be set lower to ensure a sufficiently low speed for inspectors to clearly see the tire condition.

[0048] As a typical embodiment, the specific process of calculating the number of revolutions required by the vehicle power system includes determining a minimum threshold time based on the average time of inspecting all tires of the target vehicle, where the minimum threshold time is greater than the average time, and calculating the number of revolutions required for the power system to run for at least the minimum threshold time based on vehicle tire parameters and power system parameters.

[0049] The calculation process can adopt existing technology, which will not be described in detail here.

[0050] The average time for checking all tires of the target vehicle can be determined based on historical data, or based on experiments, etc., and the source is not limited here.

[0051] As a typical embodiment, the resistance encountered needs to be greater than the operating torque to prevent accidental collision with vehicles, etc.

[0052] Through such a setting, on the one hand, if the inspector has already checked all tires in advance, artificial resistance can be applied to end the inspection process in advance and improve inspection efficiency; on the other hand, if the vehicle encounters an obstacle or emergency during driving, the vehicle can be stopped in time, the process can be stopped, and the safety of the vehicle and personnel can be ensured.

[0053] As a typical embodiment, the predetermined direction is forward, that is, the automatic driving is in D gear.

[0054] Of course, the vehicle can also be driven in reverse, depending on whether the front or the rear is more open, or whether the road conditions are better in the front or the rear.

[0055] Example 2

[0056] This embodiment provides a system for implementing the method of embodiment 1, such as Figure 2 As shown, it includes a tire check mode signal switch, a controller, an electronic parking brake system, a power system, a transmission system and an electronic gear shifting system.

[0057] The tire check mode signal switch is manually controlled by the driver.

[0058] The controller receives the tire check mode signal switch signal in real time. When the driver determines that the tire needs to be checked, the controller controls the number of revolutions of the engine or motor calculated based on the transmission ratio of the transmission system, and sends a torque instruction to the power system to ensure that the tire rolls a certain number of revolutions and provides a small torque that can enable the vehicle to move at a low speed; at the same time, the controller controls the transmission system to maintain power transmission; the controller controls the electronic parking brake system to keep the parking brake released; and the controller controls the electronic gear shifting system to remain in the D gear state.

[0059] In a typical embodiment, after the controller controls the tire to roll a certain number of times at a predetermined speed, the inspection is deemed complete and the controller controls the tire inspection mode to automatically exit. The controller controls the tire inspection mode without requiring the driver to operate. At this point, the controller controls the vehicle to engage P gear, apply the parking brake, and output zero torque from the power system.

[0060] In a typical embodiment, if the controller encounters resistance greater than the driving torque during tire check mode, such as an obstacle, the controller will stop sending torque commands and automatically exit tire check mode. At this point, the controller will engage P gear, apply the parking brake, and the controller's power system will output zero torque.

[0061] In summary, the controller enters the inspection mode by receiving the tire inspection mode signal switch signal. It is no longer necessary to repeatedly get on and off the vehicle to directly check for foreign objects around the tires, thereby improving the convenience of foreign object inspection. At the same time, the vehicle control power in this state is small, and a slight resistance can stop the vehicle. The vehicle moves very slowly, and there is no safety risk.
