The following describes a control method of the intelligent processing system for dealing with sudden tire burst of the automobile:

firstly, an automobile tire pressure monitoring system belongs to the mature prior art and becomes the standard configuration of most automobiles, and China has started to require that a car newly leaves a factory is required to be configured with the tire pressure monitoring system in 2019. In the driving process of an automobile, the ECU controller adopted by the embodiment acquires the tire pressure values of four wheels from the TPMS receiver in real time and monitors the change conditions of the tire pressure values, and the sampling time can be set to be 20ms as the time for tire burst is short and is generally less than 100 ms; the TPMS transmitters arranged on the 4 wheels transmit information such as tire pressure, temperature and the like to the TPMS receiver (in a wireless mode) at fixed time (for reducing power consumption, the time can be set to be 1 minute), and when abnormal conditions (such as overhigh tire pressure, overlow tire pressure or overhigh temperature) are monitored, the information is transmitted immediately, and if the TPMS system originally configured on the vehicle does not meet the requirements, the information needs to be replaced. Under the condition of no tire burst, the monitored numerical value is a normal tire pressure value (2.3-2.5 atmospheres), and when the tire pressure value of a certain tire is monitored continuously twice and is lower than 1.5 local atmospheres, the tire burst is judged.

When the ECU controller monitors that a certain wheel has a flat tire, the following responses are made:

1) the intelligent steering wheel stabilizing system locks the steering wheel, and the steering wheel is unlocked when the torque of the steering wheel controlled by a driver reaches a set value;

when the ECU controller detects that a tire burst occurs on a certain wheel, the steering wheel is locked at the moment of the tire burst, but the control right of the steering wheel by a driver is not completely deprived, when the driver reacts from the accident of the tire burst, the control right of the steering wheel can be obtained at any time, when the driver consciously operates the steering wheel, the steering wheel torque sensor generates an output signal, when the torque reaches a certain value (5 Nm in the embodiment), the locked steering wheel slowly releases the locked state and is controlled by the driver, so that the slow release of the brake state is to prevent the phenomenon of the steering wheel being kicked, the action principle is shown in figure 2, the steering wheel torque sensor and the belt brake for locking the steering wheel are both arranged on the steering shaft of the steering wheel, for a vehicle adopting an electric power steering system (EPAS), the steering wheel torque sensor is already arranged, therefore, only a belt brake is additionally arranged.

As mentioned above in the background art, to solve the problem of sudden tire burst during driving of a car, some manufacturers have reported to adopt a method of instantly locking a steering wheel to improve safety, and the method of completely locking the steering wheel to completely deprive a driver of the right to operate the steering wheel has certain disadvantages. For example, to the sudden tire burst problem in the straight-ahead or turning process, the steering wheel locked up in the twinkling of an eye can only make the car go or turn round along the former lane, and the utility model discloses the steering wheel locked up can prevent at first that the vehicle from turning round or toppling suddenly because of blowing out, makes the car stably go a period of time, and this can win reaction time for the driver, even if the driver has some distraction and panic before and after blowing out, also should have enough reaction time to obtain the right of control to the steering wheel, after obtaining the right of control to the steering wheel, the driver can adjust by oneself according to the circumstances that oneself is located; aiming at the problem that the tire burst happens when the vehicle is ready to turn or the vehicle enters a straight road from a curve, because the driver is in a state of full concentration and the driver is driven by holding the steering wheel tightly with both hands, the driver is unlikely to be distracted, the vehicle speed is not too high under the condition, and the reaction time left for the driver is enough under the normal condition; however, for the car not using the utility model, because it can lose the steady in the twinkling of an eye after taking place the tire burst suddenly, the steering wheel also can be out of control because of the driver's panic completely, the car can turn around even overturn suddenly, also can possibly collide with other objects or vehicles on every side to probably arouse serious traffic accident. But to having used the utility model discloses a car, the condition then probably is different completely, and the dead steering wheel of lock can prevent at least that the vehicle from turning around or toppling suddenly because of blowing out, also can prevent that the driver from taking off the steering wheel out of control because of scaring, and this just can win reaction time for the driver to make the driver probably in time obtain the control right to the steering wheel completely, in time control the vehicle and change the direction of travel. Therefore, in the two most unfavorable situations, the vehicle using the present invention is much safer than the vehicle not using the present invention.

Referring to fig. 2, under the normal running condition of the automobile, the ECU controller outputs no signal, the electromagnet YW1 of the two-position four-way electromagnetic directional valve a12 is not powered, the right position of the two-position four-way electromagnetic directional valve a12 works, the rodless cavity of the locked hydraulic cylinder slowly feeds oil through the speed regulating valve a10, the piston rod is slowly pushed to the limit position, and the steering wheel can freely rotate; when an automobile suddenly blows out, the ECU controller outputs a direction stabilizing signal YW, an electromagnet YW1 of a two-position four-way electromagnetic directional valve A12 in the intelligent steering wheel stabilizing system is electrified, the left position of the two-position four-way electromagnetic directional valve A works, a rod cavity of a locking hydraulic cylinder quickly feeds oil, a piston rod is pushed to quickly move, a brake belt 4 is tensioned through a rotating connecting rod 6, and a steering wheel 1 is quickly locked; when a driver reacts from the accident of sudden tire burst and consciously operates the steering wheel, the steering wheel torque sensor can generate an output signal, when the torque reaches a certain value (set to be 5 Nm), the ECU controller removes a direction stabilizing signal YW, an electromagnet YW1 of a two-position four-way electromagnetic directional valve A12 is de-energized, the right position of the two-position four-way electromagnetic directional valve A works, a rodless cavity of a locking hydraulic cylinder slowly feeds oil through a speed regulating valve A, a piston rod is slowly pushed, the locked steering wheel can slowly release a locking state and is controlled by the driver, and slow unlocking is adopted to prevent the phenomenon of violent driving direction caused by the operation inertia of the driver.

2) The ECU controller sends a signal to an engine ECU of an oil injection control system (comprising the engine ECU and an oil injector) to control the oil injector to stop oil injection, so that the operation is caused by the fact that a driver probably forgets to release an accelerator due to tension after sudden tire burst, and the operation aims at preventing the oil injector from injecting oil no matter whether the driver steps on the accelerator pedal or not, thereby effectively reducing the vehicle speed; until detecting that the throttle position sensor returns to zero, the normal oil injection function can be recovered after the driver completely loosens the accelerator pedal, and if detecting that the opening degree of the throttle is gradually increased from zero, the driver starts to normally control the accelerator, so that the oil injector can normally inject oil;

3) the intelligent braking system starts a snub braking mode to complete the slow braking of the automobile.

When the ECU controller detects that a certain wheel has a tire burst, the engine is cut off oil and the steering wheel is stabilized, and simultaneously the intelligent braking system is automatically started to start the intelligent snubbing mode. In addition, when the throttle position sensor returns to zero and detects a signal that the throttle opening gradually increases from zero, which indicates that the driver can normally control the accelerator and the brake, the ECU controller will remove the intelligent brake signal, and the intelligent brake system stops working, or when the vehicle speed is lower than 5 km/h, the intelligent brake system will also automatically stop working.

The action principle is shown in fig. 3, under the normal running condition of an automobile, an ECU controller has no output signal, an electromagnet YA1 of a two-position four-way electromagnetic directional valve B26 is not electrified, the right position of the two-position four-way electromagnetic directional valve B works, oil is fed into the left side of a brake hydraulic cylinder, a piston rod is pushed to the rightmost end, the piston rod is connected with a brake pedal by adopting a flexible inhaul cable 19, and under the condition that the brake pedal 17 is not trampled, the flexible inhaul cable 19 is adjusted to be in a proper tensioning state but not in a tensioning force state; because the flexible inhaul cable is adopted and no tension force is generated under normal conditions, the brake operation is not influenced, the piston rod is not influenced and is not subjected to any additional blocking force when the brake pedal 17 is stepped, the piston rod cannot be blocked, and the normal brake can be completely realized. When an automobile suddenly blows out, the ECU controller outputs a braking signal YA, an electromagnet YA1 of a two-position four-way electromagnetic reversing valve B26 in an intelligent braking system is electrified, a left position of a two-position four-way electromagnetic reversing valve B26 works, the right cavity of a brake hydraulic cylinder slowly feeds oil through a speed regulating valve B24, a piston rod is pushed to slowly move left, a brake pedal 17 is pulled to slowly rotate clockwise through a flexible inhaul cable 19, after a piston rod baffle iron 22 on the piston rod touches a brake piston rod limit switch 23 (the specific installation position of the brake piston rod is obtained through debugging), the automobile is braked, after 1 second, the ECU controller removes the braking signal YA, an electromagnet YA1 of the two-position four-way electromagnetic reversing valve B26 loses power, the right position of the two-position four-way electromagnetic reversing valve B works, the left cavity of the brake hydraulic cylinder rapidly feeds oil, and the piston rod is rapidly pushed to the rightmost end. This step is the same as the driver slowly applying a light brake pedal and then quickly releasing it to achieve a inching brake effect. After the vehicle runs for 5 seconds, the ECU controller outputs the brake signal YA again, the inching brake process finishes a work cycle again, the ECU controller completely removes the brake signal YA until the throttle position sensor returns to zero and then detects a signal that the throttle opening is gradually increased from zero or when the vehicle speed is lower than 5 kilometers per hour, and the intelligent brake system stops working completely.

Because the car is when static or the speed of a motor vehicle is lower (for example be less than 5 kilometers per hour) state, even if take place the flat tire and also can not have too big danger, consequently the utility model discloses will not respond to the flat tire under the above-mentioned circumstances, ECU controller monitors the speed of a motor vehicle promptly for this purpose.

The above detailed description of the embodiments of the present invention has been provided with reference to the accompanying drawings, but the present invention is not limited to the above embodiments, and those skilled in the art can make several equivalent transformations and substitutions without departing from the principles of the present invention after learning the contents of the present invention.
