Description

Starting control system of vehicle {Start control system of vehicle}

The present invention relates to a sudden start prevention device for a vehicle, and more particularly to a sudden start prevention device for a vehicle to prevent a sudden start occurring when the vehicle is started.

In general, in order to shift gears according to the speed of a vehicle, a manual shift method shifted by a stick operation and an automatic shift method in which gears are automatically shifted by a speed of a vehicle without a clutch are used.

According to the prior art, the automatic transmission type vehicle is located in the "D" state of the transmission, and when the accelerator is an accelerator, the vehicle starts to run, thereby causing misoperation of the clutch generated in the manual transmission type vehicle. Since malfunctions such as engine stoppage are not generated, it is possible to provide the driver with safety and convenience of driving a vehicle.

However, the above-described conventional automatic transmission vehicle starts at the "P (parking)" or "N (neutral) state and starts the vehicle by the gear shift of the" D (driving) "state. The engine is suddenly started while the engine speed is rapidly increased due to the electromagnetic wave or the driver's driving mistake, and thus the vehicle is out of the driver's control, causing an accident.

Therefore, an object of the present invention for solving the above problems, when the sudden start state of the vehicle due to the instantaneous rise of the engine is detected, the fuel supplied to the engine is cut off and at the same time the electricity supplied to the spark plug and brake It is to provide a sudden start prevention device of the vehicle to prevent the accident by the sudden start of the vehicle by operating the.

An apparatus for preventing sudden start and departure of a vehicle according to the present invention for achieving the above object, the detection means for detecting a signal applied from each sensor for detecting the operation degree of the throttle valve and the accelerator, the number of revolutions of the engine and the speed of the vehicle ; A control means for inputting a signal detected by the sensing means, and detecting sudden start of the vehicle by comparing the input signal with a set signal; Fuel blocking means for cutting off fuel supplied to the engine of the vehicle by the output of the control means; And a power cut-off means for cutting off the power supplied to the plug of the engine by the output of the control means.

Hereinafter, the configuration and operation of the present invention will be described in more detail with reference to the accompanying drawings.

1 is a block diagram showing a sudden start prevention device for a vehicle according to the present invention.

As shown, the vehicle sudden start prevention device according to the present invention, the sensing unit 10 as a sensing means, the control unit 11 as a control means, the fuel cut-off unit 12 as a fuel cutoff means, the power cut-off unit as a power cutoff means (13), a storage unit 14 as a storage means and a stop unit 15 as a stop means.

The detection unit 10 detects a signal applied from each sensor for detecting an operation degree of an accelerator, an opening degree of a throttle valve, an engine speed (RP M), and a speed of a vehicle. Preferably it is an electronic circuit comprising a micom.

The controller 11 is an electronic circuit capable of determining whether the vehicle is suddenly started by inputting a signal detected by the detector 10 and comparing the input signal with a set signal.

The fuel cutoff unit 12 cuts off the amount of fuel supplied to the engine of the vehicle by the output of the control unit 11.

The power cutoff unit 13 cuts off the power supplied to the plug of the engine by the output of the control unit 11.

The storage unit 14 is a condition of the suddenly started vehicle processed by the control unit 11, for example, the accelerator detected by the sensing unit 10 from the car, the operation degree of the brake, the engine speed, the throttle valve The opening degree and the like are recorded, and preferably include a storage device for storing information such as a hard disk, an optical disk or a memory.

The stop unit 15 is operated by the output of the control unit 11 that detects that the vehicle is suddenly started because the signal applied through the detection unit 10 is above the set level, thereby operating the brake system of the vehicle. To stop the suddenly started car.

Hereinafter, the operation of the sudden start prevention device of the vehicle according to the present invention is configured as described above.

That is, when the vehicle is started, the sensors equipped with the accelerators, brakes, engine speeds, throttle valves open, and the like are detected by the sensors, and the detected signals are applied to the sensing unit 10. .

In this way, the signal applied to the control unit 11 through the sensing unit 10 is applied to the instrument panel of the vehicle for displaying the driver so that the information corresponding to the applied signal can be identified, the engine speed, the position of the gear And output information from the instrument cluster so that the driver can know information about the state of the hand brake. For example, information about the engine speed can be obtained by using a speed meter or an RPM meter.

However, when the vehicle does not operate normally, i.e., when an abnormal sudden oscillation of the car, which is estimated to be caused by electromagnetic waves or poor driving operation, occurs immediately after starting, the detection unit 10 may operate the accelerator and rotate the engine. The number and the degree of opening of the throttle valve are identified, and the identified signal is applied to the controller 11. At this time, the control unit 11 compares the input signal with the preset information such as the accelerator operation required at the start, the engine speed and the opening degree of the throttle valve, and the like, and when the comparison result is determined to be abnormal sudden start, By controlling the fuel cutoff unit 12, the power cutoff unit 13, and the stopper unit 15, sudden start and stop of the vehicle is prevented.

In addition, when the control unit 11 determines that the start of the car is an abnormal sudden start, the information used for the determination is stored in the storage unit 14 including the hard disk or the memory, so that the accident can be analyzed later. Can be used as data.

FIG. 2 is a view showing an engine controlled by the output of FIG. 1, wherein the vehicle fuel applied into the engine by opening and closing of the intake valve 21 is exploded in accordance with the electric discharge of the plug 23, and accordingly, the piston ( 24, the exploded fuel is discharged by opening and closing the exhaust valve (22).

That is, the fuel cut-off part 12 controlled by the control unit 11 locks the valve of the solenoid 20 provided at the fuel input end of the intake valve 21 by the output of (A), so that the fuel It prevents the fuel explosion in the engine by blocking the application to the inside of the engine.

In addition, the power cut-off part 13 controlled by the control unit 11 cuts off the power applied to the spark plug 23 of the engine by the output of (B) of the fuel generated by ignition of the plug 23 in the engine. Will stop the explosion.

Therefore, the driver of the vehicle is safe because the sudden start and stop of the vehicle abnormally generated by the fuel cutoff by the valve of the solenoid 20 and the interruption of the power applied to the plug 23 are momentarily stopped.

On the other hand, Figure 3 is a view showing the operation of the brake system controlled by the output of Figure 1, when the operation of the engine is stopped by the control of the fuel cutout 12 and the power cutoff unit 13 is a car is suddenly started Although it is prevented, it is necessary to stop that the vehicle has already started suddenly by the operation of the engine generated before the control.

That is, when the valve of the solenoid 34 is opened by the output of the stopper 15 controlled by the control unit 11, the compressed air stored in the air storage unit 36 is applied to the air cylinder 32. As a result, the piston 31 protrudes, and accordingly, the brake pedal 30 is operated to stop the suddenly started vehicle, thereby preventing the sudden start of the vehicle.

On the other hand, the vacuum state of the brake booster generated by the initial operation of the engine can operate the brake booster at least once even when the engine is turned off, but when the engine is turned off, the rear end operated by pressing the brake pedal 30 The brake booster may not be operated. To prevent this, the brake booster may include a vacuum pump.

In addition, the air storage unit 36 receives air by the compressor 38 and compresses the air. The air storage unit 36 includes a pressure sensor to maintain a constant air pressure at all times, and when the pressure drops, the air storage unit 36 operates by operating the compressor 38. Compressed air. At this time, it is obvious that the compressor 38 operates by being supplied with power from an automobile.
