Description

[0002] With the rapid development of my country's economy, the number of cars is increasing, and there are more and more vehicles on the highway at a faster speed. It is inevitable that vehicles on high-speed roads will have flat tires. The immediate response to a flat tire is different. If the operation is improper, the vehicle with a flat tire may roll over or hit the vehicle in the next lane or hit the highway guardrail, causing a traffic accident with serious consequences. Therefore, there are often some braking mechanisms. The current practice is that after a flat tire occurs, the warning light is generally manually activated, the steering wheel is tightly held with both hands, the accelerator is released, and the vehicle is braked, while gradually approaching the roadside to stop the vehicle. However, due to the differences in the vehicles and the psychological qualities of the drivers, the braking process is less controllable. Many drivers and passengers do not respond correctly to a tire blowout. They often forget to activate the warning lights, brake suddenly and too hard, or rush to change gears without holding the steering wheel tightly with both hands.

[0047] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0048] A first aspect of an embodiment of the present invention provides a vehicle control system, such as Figure 1 The vehicle control system includes a vehicle control device 101, a tire pressure monitoring system 102, a vehicle braking system 103, a torque compensation system 104 and a tire deflation system 105, wherein the vehicle control device is connected to the tire pressure monitoring system, the vehicle braking system, the torque compensation system and the tire deflation system respectively. The vehicle control process of the above vehicle control system is described in detail below;

[0049] The tire pressure monitoring system is used to obtain the tire pressure of the vehicle tire in real time and send it to the vehicle control device. It can be understood that the tire pressure monitoring system is a system for obtaining the tire pressure of the vehicle tire in real time. The tire pressure monitoring system can obtain the tire pressure change of the vehicle tire in real time. Exemplarily, the above tire pressure monitoring system is also called a tire pressure monitoring system (TPMS), which can be implemented in the following ways: one is an indirect tire pressure monitoring system, which refers to determining whether the tire is abnormal by obtaining the speed difference of the tire. If the speed difference is not within the preset normal range, it is determined that the tire is abnormal, and thus the tire pressure is abnormal. The indirect tire pressure monitoring system can be an indirect tire pressure monitoring system (Wheel-Speed ​​Based TPMS, WSBTPMS), which needs to compare the speed difference between the tires through the wheel speed sensor of the vehicle's anti-lock braking system to achieve the purpose of detecting the tire pressure, and the vehicle control device feeds back the monitoring results. The other is a direct tire pressure monitoring system, which is to install multiple tire pressure monitoring sensors in the tires of the vehicle, and automatically monitor the vehicle tires in real time when the vehicle is stationary or driving, so as to obtain the changes in the tire pressure of the wheel tires. The direct tire pressure monitoring system is also called the direct tire pressure monitoring system (Pressure-SensorBased TPMS, PSBTPMS). PSBTPMS uses a pressure sensor installed on the tire to measure the tire pressure and temperature, and uses a wireless transmitter to send the pressure information from the inside of the tire to the vehicle control device.

[0050] The vehicle control device is used to determine whether the difference between the tire pressure values ​​of the vehicle tire at the first moment and the second moment sent in real time by the tire pressure monitoring system is greater than or equal to a preset threshold value, the first moment is after the second moment, and the duration between the first moment and the second moment is within the preset duration. If it is determined that the difference between the tire pressure values ​​of the vehicle tire at the first moment and the second moment is greater than or equal to the preset threshold value, it is determined that the vehicle tire has a tire burst; if it is determined that the vehicle tire has a tire burst, a first start command is sent to the vehicle braking system, a second start command is sent to the torque compensation system, and a third start command is sent to the tire deflation system.

[0051] In this step, the vehicle control device can obtain the monitoring results of the tire pressure monitoring system in real time, and make corresponding actions according to the monitoring results. Specifically, the vehicle control device is used to determine whether the difference between the tire pressure of the vehicle tire sent in real time by the tire pressure monitoring system at the first moment and the second moment is greater than or equal to the preset threshold value, the first moment is after the second moment, and the duration between the first moment and the second moment is within the preset duration. Among them, generally speaking, the change in tire pressure value before and after the tire burst is obvious and knowable, so the above-mentioned preset threshold value and preset duration are preset values. In order to improve the effectiveness of braking, reasonable values ​​can be set, as long as effective braking can be achieved to increase the probability of safe braking. It is not limited here. For example, it is determined in real time whether the tire pressure of tire A changes sharply within a preset duration (such as within 2 seconds), which indicates that tire A changes sharply and the possibility of a tire burst is very high, then it can be determined that the vehicle tire has a tire burst. If it is determined that the vehicle tire has a flat tire, a first start-up instruction is sent to the vehicle braking system to instruct the vehicle braking system to brake, a second start-up instruction is sent to the torque compensation system to instruct the torque compensation system to apply an anti-rotational torque to the steering wheel, and a third start-up instruction is sent to the tire deflation system to instruct the tire deflation system to deflate the coaxial tire corresponding to the vehicle tire.

[0052] The vehicle braking system is used to receive the first start instruction and brake the vehicle according to the first start instruction. Among them, the vehicle braking system refers to a system for braking the wheels of the vehicle. The vehicle braking system is connected to the vehicle processing device and can communicate with the vehicle processing device. The vehicle processing device can send a control command to the vehicle braking system to control the operation of the vehicle braking system. The vehicle braking system refers to a series of special devices that apply a certain force to certain parts of the car, mainly the wheels, so as to force them to brake to a certain extent. The function of the vehicle braking system is to enable a moving vehicle to be forced to slow down or even stop. Specifically, for example, the vehicle braking system can mainly be the following types of braking systems: according to the energy transmission method, it can be divided into mechanical, hydraulic, pneumatic, electromagnetic and other braking systems, or a braking system that uses more than two energy transmission methods at the same time is called a combined braking system, or it can be other servo braking systems, which are not limited here.

[0053] Optionally, the first start instruction is used to instruct the vehicle braking system to brake all wheels of the vehicle, and the vehicle braking system is used to brake the vehicle according to the first start instruction, including: the vehicle braking system is used to brake all wheels of the vehicle according to the first start instruction.

[0054] Optionally, the first start instruction is also used to instruct the vehicle braking system to change the braking force from large to small when braking all the wheels of the vehicle, and the vehicle braking system is used to brake all the wheels of the vehicle according to the first start instruction, including: the vehicle braking system is used to brake all the wheels of the vehicle at the same time according to the first start instruction, so as to reduce the braking instability caused by sudden braking and make the braking process smoother. Among them, the above braking force is an empirical value, and a suitable braking force variation range can be obtained according to the vehicle braking system and the type and weight of the vehicle. There is no specific limitation here, as long as the braking process is smoother.

[0055] The torque compensation system is used to receive the second start instruction and apply a reverse torque to the steering wheel of the vehicle according to the second start instruction. The torque compensation system refers to a system for applying a reverse torque to the steering wheel of the vehicle when a tire blows out. The torque compensation system is connected to a vehicle processing device and can communicate with the vehicle processing device. The vehicle processing device can send a control command to the torque compensation system to control the operation of the torque compensation system.

[0056] Optionally, before the vehicle control device sends the second start instruction to the torque compensation system, the vehicle control device is further used to: determine the tire position of the vehicle tire; determine the direction of the anti-rotation torque of the steering wheel according to the tire position; generate the second start instruction according to the direction of the anti-rotation torque, and the second start instruction is used to instruct the torque compensation system to apply the anti-rotation torque in the same direction as the anti-rotation torque to the steering wheel of the vehicle;

[0057] The torque compensation system is used to apply an anti-rotational torque to the steering wheel of the vehicle according to the second start-up instruction, including: the torque compensation system is used to apply the anti-rotational torque in the same direction as the anti-rotational torque to the steering wheel of the vehicle according to the second start-up instruction.

[0058] When a vehicle is driving on a highway, a tire blowout is one of the important factors that cause serious traffic accidents. After a tire blowout, the driving resistance of the tire wheel increases sharply, the rolling radius decreases, and the adhesion to the ground decreases sharply. A large steering wheel angle can easily cause the rim to touch the ground, resulting in the separation of the tire rim. After a tire blowout, the vehicle body shakes, causing the driving direction to deviate from the original direction. At this time, the driver often turns the steering wheel greatly and slams on the brakes due to panic. These improper operations cause the high-speed vehicle to skid or roll over sharply under the action of inertia, and the driving direction loses control, causing serious traffic accidents. Therefore, in order to avoid causing the driving direction to deviate from the original direction, the embodiment of the present invention also adds a torque compensation system, so that when the driving direction deviates from the original direction, the anti-rotation torque is applied to the steering wheel of the vehicle to prevent the tire rim from separating due to the large ground braking force, causing the vehicle to lose control. Specifically, the vehicle control device can determine the tire position of the vehicle tires; determine the direction of the anti-rotation torque of the steering wheel according to the tire position. Taking a four-wheeled vehicle as an example, when a tire bursts at wheels in different positions, the vehicle loses balance in different situations, which will cause the vehicle to deviate in different directions, causing the driving direction to deviate from the original direction, and also causing the steering wheel to deviate from the direction. At this time, the direction of the anti-rotation torque of the steering wheel can be determined according to the tire position, and a signal is sent to the torque compensation system to instruct the torque compensation system to apply the anti-rotation torque in the same direction as the anti-rotation torque to the steering wheel of the vehicle. In this way, the torque compensation system can apply the anti-rotation torque in the same direction as the anti-rotation torque to the steering wheel of the vehicle. In addition, specifically, in an embodiment of the present invention, the torque compensation system can also limit the steering wheel angle within a plurality of preset safe angle ranges according to different driving speeds after a tire blowout. The torque compensation system can send control information to the angle sensor and torque sensor corresponding to the steering wheel according to the determined safe angle range. The steering wheel angle range is controlled by the angle sensor and torque sensor, and the steering wheel is locked within the safe angle range, thereby effectively avoiding the situation where the driving direction deviates from the original direction when a tire blowout occurs, and further effectively reducing the danger after a tire blowout accident occurs.

[0059] The tire deflation system is used to receive the third start instruction, and according to the third start instruction, the coaxial tire corresponding to the vehicle tire is deflated. The tire deflation system refers to a system for deflating the coaxial tire corresponding to the vehicle tire with a blowout when the vehicle has a blowout. The tire deflation system is connected to the vehicle processing device and can communicate with the vehicle processing device. The vehicle processing device can send a control command to the tire deflation system to operate the tire deflation system. In a specific implementation, the tire position relationship of all tires of the vehicle can be pre-identified. After determining the tire with a blowout, the coaxial tire of the blowout tire can be determined according to the tire position relationship, thereby implementing the deflation operation of the coaxial tire. Through the above-mentioned deflation operation, the two coaxial tires can be in a parallel state. For example, if the front left tire blows out, the front right tire is deflated, so that the front left and right tires are balanced, the vehicle is prevented from tilting to the left, the overall tilt of the vehicle is reduced, and the danger after the blowout occurs is effectively reduced. Specifically, the tire deflation system can adopt a central tire deflation system, etc., which is not limited here.

[0060] It can be seen that in the above scheme, when a tire blowout occurs, the three processing mechanisms of the vehicle braking system, the torque compensation system, and the tire deflation system can work together to control the vehicle to stop smoothly, avoid the occurrence of traffic accidents such as rollover, reduce the danger after the tire blowout accident, and improve safety.

[0061] Alternatively, if Figure 2 As shown, the vehicle control system also includes a vehicle alarm system 106, and the vehicle alarm system is connected to the vehicle control device; the vehicle control device is also used to send a fourth start-up instruction to the vehicle alarm system after determining that the vehicle tire has a flat tire; the vehicle alarm system is used to receive the fourth start-up instruction and issue an alarm indication according to the fourth start-up instruction. That is to say, the vehicle control system provided in the embodiment of the present invention also includes a vehicle alarm system, and the vehicle alarm system is connected to the vehicle control device and can communicate with the vehicle control device. The vehicle control device can send a control command to the vehicle alarm system to control the operation of the vehicle alarm system. Specifically, optionally, the vehicle alarm system includes a vehicle alarm light, and the fourth start-up instruction is used to instruct the vehicle alarm system to turn on the flashing of the vehicle alarm light. By automatically turning on and flashing the vehicle alarm light, surrounding vehicles can be prompted to pay attention to avoid, thereby further reducing the danger.

[0062] Optionally, if it is determined that the vehicle tire has a flat tire, the first, second, third and fourth start-up instructions are sent simultaneously. In this way, by initiating the above four instructions at the same time, the above four mechanisms are made to work together and at the same time, further reducing the danger after a flat tire.

[0063] like Figure 3 As shown, based on the above vehicle control system, the present invention implements a corresponding vehicle control method, which is applied to a vehicle control device in the vehicle control system, wherein the vehicle control system also includes a tire pressure monitoring system, a vehicle braking system, a torque compensation system and a tire deflation system, wherein the vehicle control device is connected to the tire pressure monitoring system, the vehicle braking system, the torque compensation system and the tire deflation system respectively, and the method includes the following steps:

[0065] S20: Determine whether the difference between the tire pressure values ​​of the vehicle tire at the first moment and the second moment is greater than or equal to a preset threshold, the first moment is after the second moment, and the time between the first moment and the second moment is within the preset time;

[0066] S30: If it is determined that the difference between the tire pressure values ​​of the vehicle tire at the first moment and the tire pressure value at the second moment is greater than or equal to a preset threshold, it is determined that the vehicle tire is punctured;

[0069] S60: Sending a third start instruction to the tire deflation system, so that the tire deflation system performs a deflation operation on the coaxial tire corresponding to the vehicle tire.

[0070] Alternatively, if Figure 4 As shown, the vehicle control system also includes a vehicle alarm system, and the method further includes the following steps:

[0071] S70: If it is determined that the vehicle tire has a flat tire, a fourth start instruction is sent to the vehicle alarm system, so that the vehicle alarm system issues an alarm indication according to the fourth start instruction.

[0072] It should be noted that it should be understood that the size of the serial numbers of the steps in the above embodiments does not mean the order of execution. The execution order of each process should be determined by its function and internal logic, and should not constitute any limitation on the implementation process of the embodiments of the present invention. Figure 3 and Figure 4There is no execution order relationship among steps S40-S60 or S40-S70, and no limitation is made here. Optionally, if it is determined that the vehicle tire has a flat tire, the first, second, third and fourth start instructions are sent simultaneously.

[0073] Optionally, before sending the first start instruction to the vehicle braking system, a first start instruction is generated to instruct the vehicle braking system to brake all wheels of the vehicle.

[0074] Optionally, the first start instruction is also used to instruct the vehicle braking system to brake all wheels of the vehicle with the braking force changing from large to small.

[0075] Optionally, before sending a second start-up instruction to the torque compensation system, the tire position of the vehicle tire is determined; the direction of the anti-rotation torque of the steering wheel is determined based on the tire position; and the second start-up instruction is generated based on the direction of the anti-rotation torque, wherein the second start-up instruction is used to instruct the torque compensation system to apply the anti-rotation torque in the same direction as the anti-rotation torque to the steering wheel of the vehicle.
