Abstract
The invention relates to a method for controlling front flat tyre smoothly, which is characterized by comprising the following steps: obtaining the linear speed of a wheel by multiplying the wheel diameter which is converted from the tyre pressure measured by a tyre pressure monitoring unit by the wheel rotating speed measured by a wheel rotating speed sensor through a microcomputer; making a real-time comparison between the linear speed of a flat tyre wheel and the linear speeds of other normal wheels; and controlling the wheel brake by applying a variable braking pressure to the normal wheels through a method for controlling the braking pressure so that the linear speed of the wheels is kept equal so as to achieve the smooth control of a vehicle. The technique for controlling the front flat tyre smoothly can solve the problems that once a motor vehicle has a tyre which bursts in the driving process, the vehicle goes round, rolls over, and deflects the driving direction, and cannot brake to stop in time, thus the method can greatly reduce the occurrence of terrible traffic accidents.
Description
Technical field
After the present invention relates to vehicle front-wheel one side and blowing out, realize vehicle steadily being controlled system, particularly a kind of method for controlling front flat tyre smoothly with the method for control wheel brake pressure.
Background technology
In case power actuated vehicle front-wheel is in the process of moving blown out, because the back tire pressure of blowing out descends rapidly, resistance wheel is increased, diameter diminishes, and linear velocity reduces.Because vehicle both sides wheel linear velocity difference, the travel direction of vehicle can be to the right deflection of wheel one pleurapophysis of blowing out, travel direction is difficult to control, the torsion of bearing circle deflection tends to control greater than the driver its strength, will automaticly depress brake pedal at this clutch chaufeur brakes, the resistance of the wheel of blowing out is further strengthened, make vehicle spin, roll, cause the generation of pernicious traffic accident.
Summary of the invention
The present invention has overcome the defective of above-mentioned existence, purpose is that the tire pressure signal by wheel converts wheel diameter to, and wheel diameter and vehicle wheel rotational speed by Computing, are drawn the wheel linear velocity, one-tenth provides a kind of method for controlling front flat tyre smoothly in order to reduce the generation of pernicious traffic accident.
Method for controlling front flat tyre smoothly content Description of the present invention:
Method for controlling front flat tyre smoothly of the present invention is characterized in that: be to constitute front-wheel tyre-burst trim control system for tree device by the tyre pressure monitoring measurement unit, wheel speed sensor, ECU (Electrical Control Unit), braking pressure control unit, the reset switch that are installed in the car; Be installed in 4 wheel speed sensors in the wheel respectively, the wheel cylinder that is provided with in wheel is connected with the braking pressure control electromagnetic valve by oil pipe, the braking pressure control electromagnetic valve is connected with liquid reserve tank, master control electromagnetic valve, master cylinder by oil pipe, and the master control electromagnetic valve is connected with pressure accumulator, motor-drive pump by oil pipe; Adopt microcomputer that the tire pressure that the tyre pressure monitoring measurement unit records is converted to wheel diameter, the vehicle wheel rotational speed product that records with wheel speed sensor draws the wheel linear velocity, the linear velocity of the wheel of blowing out and the linear velocity of other normal wheels are done real-time comparison, and the automatic pressure control wheel braking that normal wheels is applied variation with the method for control brake pressure makes the linear velocity of each wheel keep equating to reach steady control to vehicle;
The tyre pressure monitoring measurement unit: the actual measured amount tire pressure is transmitted into and monitors on the receptor during by the tire air pressure sensor producer of direct-type, receive monitoring device and show tire pressure and pass to the gradual braking system that blows out, or will pass to the gradual braking system that blows out by the tire pressure that the wheel speed information translation becomes by indirect type [TPMS];
Microcomputer carries out operational analysis according to tire pressure signal and vehicle wheel rotational speed signal, and output command is given control circuit, and the control circuit control electromagnetic valve is moved, and each wheel is applied the brake-pressure of variation.
In case the steady control technology of front-wheel tyre-burst of the present invention can solve power actuated vehicle in the process of moving wheel blow out can make that vehicle spins, rolls, travel direction deflection, the timely problem of stopping-down, can significantly reduce the generation of pernicious traffic accident.
The specific embodiment
Method for controlling front flat tyre smoothly of the present invention is to realize like this, vehicle in motion, when a certain wheel is blown out suddenly or gas leakage fast, when tire pressure drops to predetermined early warning value, tire pressure Pressure monitoring unit sends alerting signal, and the tire pressure signal is passed to the ECU (Electrical Control Unit) arithmetical circuit of the steady control technology of front-wheel tyre-burst system, the linear velocity that calculates front-wheel according to the tire pressure and the vehicle wheel rotational speed of both sides front-wheel, compare in real time, when the linear velocity of the normal side front-wheel of tire pressure is crossed low wheel and is promptly blown out wheel greater than tire pressure, output command control circuit outgoing current starts the master control electromagnetic valve of 4 wheels, with motor-drive pump, oil circuit between pressure accumulator and the master cylinder is connected, close motor-drive pump and lead to the oil return circuit of liquid reserve tank, for system provides continuous high hydraulic brake fluid, and light stoplight stop lamp and the Warning light of meeting an urgent need, export big electric current simultaneously and give the braking pressure control electromagnetic valve of the wheel of blowing out, oil circuit between master cylinder and the wheel cylinder is closed, the brakes on wheel cylinder leads to the oil circuit of liquid reserve tank, makes the brake system of the wheel of blowing out be in decompression state.
After the wheel of not blowing out is subjected to formulation power, linear velocity begins to descend, when the linear velocity of certain wheel equals to blow out the wheel linear velocity, the computing machine output command starts this wheel brake pressure control electromagnetic valve action, close the oil circuit between wheel cylinder and the master cylinder, make this wheel gradual braking system that blows out be in braking and press from hold mode.
When the linear velocity of certain wheel is lower than when blowing out the wheel linear velocity, computing machine output command control circuit is exported big electric current, controls this wheel brake pressure control electromagnetic valve action, the oil circuit between brakes on wheel cylinder and the liquid reserve tank.
Make the linear velocity of 4 wheels of vehicle keep equating by cycle control, therefore eliminated the phenomenon that travel direction deflection appears in the back vehicle of blowing out, reach steady parking the wheel brake pressure of not blowing out.Press reset switch and remove the gradual braking system that blows out, the control system of vehicle can be recovered normal condition.
