Description

BACKGROUND OF THE INVENTION 1. Field of the Invention [0001] The present invention relates to an apparatus for preventing an automobile from suddenly accelerating,

The present invention relates to an apparatus for preventing sudden stoppage of an automobile, and more particularly, to an apparatus for preventing a sudden stoppage of an automobile by controlling an amount of intake air supplied to an engine in the event of a sudden occurrence of an automobile, and a control method thereof.

BACKGROUND ART [0002] In recent years, an automobile is required to determine a required torque amount in accordance with the power of an accelerator pedal, the number of engine revolutions and the speed change stage, and to drive a DC motor mounted on a throttle body on the basis of a determined required torque amount to control the opening degree of a throttle valve An electronic throttle control (ETC) device is applied.

Such an ETC apparatus may be controlled by an electronic control unit (ECU) or a cruise control unit (CCU) of the vehicle according to the state of the accelerator pedal. do.

Accordingly, the ETC apparatus can precisely control the ignition timing and the fuel injection amount of the engine by correctly opening and closing the throttle valve by the operation of the motor without connecting the accelerator pedal and the throttle valve with cables, so that the response of the engine is made dynamically , The noise generated by existing cables can be greatly reduced.

On the other hand, when the ETC device is applied to an automobile and a malfunction of the ECU for controlling the ETC device occurs, the vehicle often suddenly advances or retreats suddenly in the absence of the accelerator pedal and the shifting operation.

An example of a technique for preventing the sudden development of such a car is disclosed in Korean Patent Publication No. 10-2011-0116689 (published on October 26, 2011, hereinafter referred to as Patent Document 1), Korean Patent Publication No. 10-2001 -0026291 (published on Apr. 6, 2001, hereinafter referred to as Patent Document 2), Korean Patent Registration No. 10-0356065 (published on October 9, 2002, hereinafter referred to as Patent Document 3) Korean Patent Publication No. 10-2012-0017690 (published on February 29, 2012, hereinafter referred to as "Patent Document 4").

In Patent Document 1, the ECU determines the running state of the vehicle based on the vehicle speed, the engine speed, the throttle position value, the gear position value, and the like.

If a brake signal is input in a normal vehicle driving state, the ECU determines that the vehicle is in a sudden acceleration state and controls the engine rotational speed to be kept idle.

In Patent Document 2, when a sudden acceleration occurs, the clutch is forcibly separated from the transmission in a transmission control unit (hereinafter, referred to as "TCU") to prevent a sudden accident.

However, Patent Documents 1 and 2 judge a sudden acceleration by using an ECU or a TCU, and therefore, when a malfunction of the ECU or the TCU itself occurs, the engine speed and the clutch can not be appropriately controlled, there was.

In addition, in Patent Document 3, since the air conditioning device for adjusting the injection amount of air is installed separately from the ETC device in order to prevent the sudden stoppage, the manufacturing cost is increased and the operation is performed according to the switch operation of the driver. There was a problem.

On the other hand, Patent Document 4 discloses that a suddenly stopping prevention unit is attached to a terminal of an on-board diagnostics (OBD) provided in an automobile and a vehicle speed down and engine start off control is performed using a CAN signal do.

The OBD monitors the exhaust gas control component or system of the vehicle, guides the driver when a fault is diagnosed, and provides a stored fault history when an external tester is connected.

However, in Patent Document 4, in order to judge whether or not a sudden acceleration occurs by using the video vehicle speed information and the multi-vehicle speed information in the suddenly-emergence prevention unit, a camera module and a security authentication module, a video vehicle speed signal generator, a vehicle speed signal collection / A control signal generating unit, and the like, the configuration and control procedures are complicated and manufacturing costs are increased.

In Patent Document 4, when a sudden acceleration is sensed, only the vehicle ECU, the TCU, and the cluster controller transmit only the vehicle speed reduction, the engine start off, and the warning light alarm control command, but can not perform the function of preventing sudden emergence there was.

The ETC module 10 includes a throttle valve 11 installed in a throttle body (not shown) for opening and closing a passage inside the throttle body, a motor 12 for generating a driving force for opening and closing the throttle valve 11, And a throttle position sensing unit 13 for sensing the position of the throttle valve 11.

In this embodiment, the motor 12 uses a brushless DC motor, and may be changed to a brush-type DC motor.

The throttle position sensing unit 13 senses the position of the throttle valve 11 and transmits a throttle sensing signal according to the sensed position of the throttle valve to the vehicle controller 30. [

In this way, the throttle detection signal transmitted to the vehicle controller 30 is transmitted to the rapid-motion control unit 40 connected to the OBD terminal 31.

The pedal position sensing unit 20 is installed at an upper portion of the accelerator pedal 21 to sense the displacement of the accelerator pedal 21 and to transmit a pedal sensing signal corresponding to the detected displacement of the accelerator pedal to the vehicle controller 30 and the rapid- 40).

The vehicle control unit 30 is an ECU or other control unit that controls the driving of each device provided in the vehicle, and generates a control signal for controlling the driving of the ETC module 10 based on the detection signals of various sensors installed in the vehicle.

Here, the vehicle control unit 30 generates driving state information of the vehicle in response to a sensing signal transmitted from various sensors installed in the vehicle such as a throttle position sensor, an accelerator pedal sensor, a brake pedal sensor, a vehicle speed sensor, and a water temperature sensor.

The running state information of the vehicle may include a running speed of the vehicle, an RPM, a coolant temperature, an output torque of the engine, brake operation information, a throttle opening amount, pedal position information, and the like.

Here, the engine torque can be divided into the required torque (target torque) and the output torque of the engine, but in this embodiment, the required torque will be described by the engine torque.

The vehicle control unit 30 transmits the generated running state information of the vehicle to the rapid-motion control unit via the OBD terminal 31. [

On the other hand, the OBD terminal 31 includes an OBD2 terminal which has been used in the past, and an OBD2 terminal which has been recently used and is commonly used.

The signal selection unit 50 is connected between the motor 12 and the vehicle control unit 30 and the rapid acceleration control unit 40 and is connected to the signal selection unit 50. The signal selection unit 50 selects one of the control signal of the vehicle control unit 30 and the motor drive control signal of the rapid acceleration control unit 40 And transmits it to the motor 12.

That is, the signal selection unit 50 normally transmits the control signal of the vehicle control unit 30 to the motor 12, and when the motor drive control signal of the interrupt signal type is generated from the rapid acceleration control unit 40, 12).

Such a signal transmitting unit 50 may be provided with a switching element such as a relay.

The rapid-motion control unit 40 is made of one module connectable to the OBD terminal 31. [

The rapid-motion control unit 40 includes a communication unit 41 for receiving the running state information of the vehicle, a determining unit 43 for determining whether or not the sudden driving is generated by analyzing the running state information of the received vehicle, And a signal generator 44 for generating a motor drive control signal in the form of an interrupt signal to the motor 12 so as to adjust the amount of intake air supplied to the motor 12.

The suddenly driving control unit 40 compares the pedal sensing signal and the pedal sensing signal directly received from the pedal position sensing unit 20 among the driving state information received through the OBD terminal 31 in the communication unit 41, And an inspection unit 42 for checking whether a delay has occurred or an error has occurred.

The inspector 42 determines that the vehicle controller 30 is in a malfunction state when the delay time exceeds the preset delay range or the error of the value of each pedal detection signal exceeds a predetermined error range in the signal reception process.

To this end, the communication unit 41 receives the traveling state information of the vehicle transmitted through the OBD terminal 31 and receives the pedal detection signal from the pedal position sensing unit 20. [

The determination unit 43 compares the pedal detection signal, the throttle detection signal, the brake operation signal, and the engine torque among the running state information of the vehicle when the inspection result signal of the inspection unit 42 is delayed or an error occurs, It is judged whether or not it occurs.

For example, the determination unit 43 determines whether abnormality of the engine torque and the throttle detection signal relative to the pedal detection signal occurs, whether an abnormality occurs in the engine torque and the pedal detection signal relative to the brake operation signal, the pedal detection signal in response to the throttle detection signal, It is possible to judge whether or not a sudden occurrence occurs.

The signal generating unit 44 generates a signal indicating that the throttle valve 11 is in the idle state when it is judged that the test result of the inspection unit 42 is delayed or an error occurs, And generates a motor drive control signal for controlling the drive of the motor 12 so as to be opened by the throttle opening amount.

The motor drive control signal generated in the signal generator 44 may be transmitted to the motor 12 through the electric wire connecting the signal generator 44 and the motor 12 of the ETC module 10, Or may be delivered via wireless communication.

For this purpose, the rapid-motion control unit 40 may further include a communication module (not shown) for performing wireless communication in various ways such as WiFi and Bluetooth.

In addition, the rapid-motion control unit 40 may further include a storage unit 45 for storing driving state information from a predetermined set time, for example, about 30 seconds before the sudden emission occurs.

As described above, according to the present invention, it is possible to prevent an accident caused by sudden driving by determining whether or not a sudden occurrence of an automobile occurs by using driving state information of a vehicle transmitted through an OBD terminal, and adjusting an amount of intake air supplied to the engine when a sudden driving is generated .

Particularly, according to the present invention, it is possible to accurately determine whether a sudden occurrence of an automobile occurs or not by determining whether the vehicle suddenly starts using the pedal detection signal, the throttle detection signal, the engine torque, and the brake operation signal.

Further, according to the present invention, a pedal sensing signal received through an OBD terminal is compared with a pedal sensing signal transmitted directly from a pedal position sensing unit to check whether a signal is delayed or an error is generated, Can be determined.

Also, the present invention may provide driving state information from a predetermined set time before a sudden acceleration occurs, in a storage unit, and provide data for analyzing the cause of a sudden accident using stored information.

Next, a control method of the vehicle suddenly stopping device according to a preferred embodiment of the present invention will be described in detail with reference to FIG. 2 to FIG.

FIG. 2 is a flowchart illustrating a method of controlling the suddenly stopping device of an automobile according to a preferred embodiment of the present invention, and FIG. 3 is a flowchart illustrating step S30 of FIG. 2 in detail.

And Fig. 4 is an exemplary diagram of an engine torque graph at the time of a brake operation.

4A is a graph showing measured values of the vehicle speed and the engine torque at the time of the brake operation test using the diesel SUV vehicle and FIG. A graph of measured torque is shown.

As shown in FIG. 2, the control method of the vehicle suddenly stopping device according to the preferred embodiment of the present invention starts driving while the ignition key of the automobile is operated to turn on the engine (S10).

Then, the vehicle control unit 30 receives the sensing signals sensed by various sensors installed in the vehicle, and generates driving state information of the vehicle including the sensing signals.

At this time, the communication unit 41 of the rapid-acceleration control unit 40 receives the traveling state information of the vehicle through the OBD terminal 31 and receives the pedal detection signal from the pedal position sensing unit 20 connected by a separate wire (S20 ).

In step S30, the rapid-motion control unit 40 checks whether the running state information of the vehicle is in the normal range.

Step S30 will be described in detail with reference to FIG.

3, in step S31, the inspector 42 compares the pedal detection signal received through the OBD terminal 31 with the pedal detection signal received from the pedal position sensing unit 20 to generate a signal delay or an error .

If the delay time between the pedal detection signals exceeds the predetermined delay range or the error exceeds the error range, the checking unit 42 determines that the malfunction of the vehicle control unit 30 has occurred and proceeds to step S40.

If it is determined in step S31 that the pedal detection signals are within the normal delay time and error range, the determination unit 43 determines in step S32 that the other signals included in the running state information of the vehicle in response to the pedal detection signal, It is checked whether the value of the detection signal is in the normal range.

That is, when the engine torque included in the running state information of the vehicle is equal to or greater than a preset appropriate range or the value of the throttle position detecting signal relative to the pedal detecting signal is equal to or greater than a preset normal range, .

In step S33, the determination unit 43 determines whether the vehicle speed and the engine torque in comparison with the brake operation signal exceed the limit line L of the graph shown in Figs. 4A and 4B.

That is, when the brake operation signal is input, the determination unit 43 determines that the vehicle is in an abnormal state when the speed of the vehicle and the engine torque are higher than the limit line and the pedal detection signal is not off .

In step S34, the determination unit 43 determines whether the pedal detection signal and the engine torque value in comparison with the throttle detection signal are in a normal range.

That is, the determination unit 43 may determine that the pedal detection signal is out of the preset normal range or the abnormal state when the engine torque value is out of the predetermined normal range with respect to the throttle detection signal.

If it is determined in step S31 to step S34 that any one or more of them is abnormal, the determination unit 43 determines in step S40 of FIG. 2 that there is a malfunction or a sudden onset of the vehicle control unit 30.

Then, in step S50, the signal generating unit 44 of the rapid-acceleration control unit 40 generates a motor drive control signal for driving the throttle valve 11 so as to correspond to the throttle opening amount in the idle state.

As described above, according to the present invention, since the amount of intake air supplied to the engine of the vehicle is adjusted to the idle state by using the motor drive control signal of the rapid acceleration control unit, the vehicle having the sudden acceleration is returned to the idle state, have.

On the other hand, the rapid-motion control unit 40 generates a warning lamp lighting signal to illuminate a warning lamp (not shown) provided on the instrument panel of the vehicle through the communication unit 41 to inform the driver of a malfunction or sudden emergence of the vehicle control unit 30 And transmit it via the OBD terminal 31 to the warning lamp.

In addition, the rapid-acceleration control unit 40 stores the running state information of the vehicle in the storage unit 45 from a predetermined time, for example, about 30 seconds before the instant of occurrence of the sudden acceleration, Data can be provided.

In step S60, the rapid-motion control unit 40 receives the running state information of the vehicle again to check whether the vehicle's engine is maintained in the idle state.

If it is determined in step S60 that the engine is not in the idle state, the sudden-discharge control unit 40 proceeds to step S50 to repeat the process of controlling the intake air amount to the idle state.

On the other hand, if it is determined in step S60 that the engine is maintained in the idle state, the rapid-acceleration control unit 40 checks whether the ignition key is operated to input the start-off signal, and steps S30 to S70 .

If the start-off signal is input in step S70, the sudden-discharge control unit 40 stops the sudden-discharge inspection process and terminates.

According to the above-described process, the present invention determines whether a malfunction or a sudden acceleration of the vehicle control unit occurs or not, by using the driving state information of the vehicle transmitted through the OBD terminal, and adjusts the amount of intake air supplied to the engine to an idle state So that accidents caused by sudden emergence can be prevented.

Although the present invention has been described in detail with reference to the above embodiments, it is needless to say that the present invention is not limited to the above-described embodiments, and various modifications may be made without departing from the spirit of the present invention.

The present invention uses a driving state information of a vehicle transmitted through an OBD terminal to determine whether a malfunction or a sudden acceleration of a vehicle control unit has occurred and adjusts the amount of intake air supplied to the engine to an idle state to prevent accidents Technology.
