Description

FIELD OF THE INVENTION [0001] The present invention relates to a power steering operation based fuel compensation system,

[0001] The present invention relates to a fuel compensation method for a vehicle engine, and more particularly, to a fuel compensation method for a vehicle engine, in which a power steering input signal repeatedly repeated due to slight handling by a driver is discriminated, And more particularly, to a power steering operation based fuel compensation system and method thereof for performing fuel compensation.

When an input signal corresponding to the driver's power steering operation is received among a plurality of input signals that determine the driving speed of the engine, the engine driving speed is artificially increased by additionally compensating the fuel as much as the load due to the power steering operation, Thereby preventing collision and stopping of the vehicle.

However, the power steering input signal may be input incorrectly depending on the degree of assembly and completion or aging of the vehicle. In the related art, it is difficult to discriminate whether the incorrect input is caused by the fine handling of the driver or the assembling problem of the vehicle itself, so that the input data is judged as noise and the fuel compensation is not performed.

Accordingly, in the case of the power steering input signal due to the fine handling, the steering wheel is excluded from the fuel compensation logic, so that there is a problem in that the steering and steering motions of the engine occur due to the load of power steering in the idle state of the engine.

SUMMARY OF THE INVENTION The object of the present invention is to provide a steering angle sensor that senses whether an input signal is received from a power steering of a vehicle according to a set period, And determines whether or not the power steering input signal is normal based on the result of the check. If the power steering input signal is determined to be normal, the amount of air flowing into the engine for compensating the fuel amount is set In the idle state of the vehicle by providing a power steering operation based fuel compensation system and a method of increasing the power steering operation based fuel compensation system and method.

According to an aspect of the present invention, there is provided a power steering operation based fuel compensation system comprising: a signal sensing unit for sensing whether an input signal is received from a power steering of a vehicle according to a set period; A signal discrimination unit for checking whether the input signal is maintained in the sensing state for a predetermined filtering time when the reception of the input signal is detected and determining whether the signal is a normal signal for the power steering input signal based on a result of the checking; And an air amount controller for increasing the amount of air flowing into the engine by a predetermined value to compensate the fuel amount when the power steering input signal is determined to be normal.

Preferably, the signal discrimination unit discriminates the power steering input signal as a normal signal when the sensing state of the input signal is maintained during the filtering time.

Preferably, the signal discrimination unit discriminates the power steering input signal as an abnormal signal when the filtering time elapses or the sensing state of the input signal is not maintained during the filtering time.

According to another aspect of the present invention, there is provided a power steering operation based fuel compensation method, comprising: a signal sensing step of sensing whether an input signal is received from a power steering of a vehicle according to a set period; A state checking step of checking whether the input state of the input signal is maintained for a predetermined filtering time period when the input signal is received; Determining whether the power steering input signal is a normal signal based on the check result; And an air amount control step of increasing the amount of air flowing into the engine by a set value in order to compensate the fuel amount when the power steering input signal is determined to be normal.

Preferably, the signal discriminating step discriminates the power steering input signal as a normal signal when the sensing state of the input signal is maintained during the filtering time.

Preferably, the signal discriminating step discriminates the power steering input signal as an abnormal signal when the filtering time has elapsed or the sensing state for the input signal is not maintained during the filtering time.

Accordingly, according to the power steering operation-based fuel compensation system and method of the present invention, as in the case of a normal power steering input corresponding to the power steering input signal due to the slight handling of the driver, By performing the compensation, it is possible to prevent the occurrence of engine stopping and stopping in the idle state of the vehicle.

1 is a schematic configuration diagram of a power steering operation based fuel compensation system according to an embodiment of the present invention;
FIG. 2 is a schematic flow chart for explaining a power steering operation-based fuel compensation method according to an embodiment of the present invention; FIG.

Hereinafter, preferred embodiments of the present invention will be described with reference to the accompanying drawings.

FIG. 1 shows a schematic diagram of a power steering operation based fuel compensation system according to an embodiment of the present invention.

As shown in FIG. 1, the system includes a signal sensing unit 100 for sensing whether an input signal is received from power steering, a signal determining unit 200 for determining whether the signal is a normal signal for the power steering input signal, And an air amount control unit 300 for increasing the amount of air flowing into the engine for compensation.

The signal sensing unit 100 senses whether an input signal is received from the power steering of the vehicle. More specifically, the signal sensing unit 100 senses an input signal received from a power steering of the vehicle according to a set period. At this time, the input signal may be classified into a power steering input signal according to a normal steering operation, a power steering input signal due to a slight handling of the driver, and a noise due to a relief of a power steering pressure.

When the reception of the input signal is detected, the signal determination unit 200 determines whether the input state of the input signal is maintained for a predetermined filtering time, and determines whether a normal state of the power steering input signal . More specifically, when the sensing state of the input signal is maintained during the filtering time, the signal discrimination unit 200 outputs the power steering input signal as a normal signal, that is, a power steering input signal according to a normal steering operation, It is determined as a power steering input signal due to fine handling. On the other hand, when the filtering time has elapsed or the sensing state of the input signal is not maintained during the filtering time, the signal determining unit 200 determines that the power steering input signal is an abnormal signal, that is, As shown in FIG.

The air amount control unit 300 increases the amount of air flowing into the engine to compensate the fuel amount. More specifically, when the power steering input signal is determined to be normal, the air amount control unit 300 increases the amount of air flowing into the engine to compensate for the fuel amount by a set value, so that additional fuel flows into the engine So that the driving speed (rpm) of the engine is increased to prevent the occurrence of stagnation and stoppage of the engine.

As described above, according to the power steering operation-based fuel compensation system according to the embodiment of the present invention, the power steering input signal repeatedly repeated due to the slight handling of the driver is discriminated as a normal signal, Air amount compensation is performed to perform a certain amount of fuel compensation, thereby preventing the engine from being stalled and stopped.

Hereinafter, a power steering operation based fuel compensation method according to an embodiment of the present invention will be described with reference to FIG. In addition, for convenience of description, the components shown in FIG. 1 will be described with reference to corresponding reference numerals.

First, it is detected whether an input signal is received from the power steering of the vehicle according to the set period (S100). Preferably, the signal sensing unit 100 senses an input signal received from a power steering of the vehicle according to a set period. At this time, the input signal may be classified into a power steering input signal according to a normal steering operation, a power steering input signal due to a slight handling of the driver, and a noise due to a relief of a power steering pressure.

Then, it is checked whether the input state of the input signal is maintained (S200). Preferably, when the signal discrimination unit 200 detects the reception of the input signal, the signal discrimination unit 200 confirms whether the sensed state of the input signal is maintained for a predetermined filtering time.

Then, it is determined whether the power steering input signal is a normal signal based on the check result (S300). Preferably, when the signal determining unit 200 maintains the sensing state for the input signal during the filtering time, the power steering input signal is converted into a normal signal, that is, a power steering input signal according to a normal steering operation, It is determined as a power steering input signal due to fine handling. On the other hand, when the filtering time has elapsed or the sensing state of the input signal is not maintained during the filtering time, the signal determining unit 200 determines that the power steering input signal is an abnormal signal, that is, As shown in FIG.

Thereafter, when the power steering input signal is determined to be normal, the amount of air flowing into the engine for compensating the fuel amount is increased by a set value (S400). Preferably, when the power steering input signal is determined to be normal, the air amount control unit 300 increases the amount of air flowing into the engine to compensate for the amount of fuel by a set value, so that additional fuel flows into the engine corresponding to the increased amount of air. So that the driving speed (rpm) of the engine is increased to prevent the occurrence of stagnation and stoppage of the engine.

As described above, according to the power steering operation based fuel compensation method according to the embodiment of the present invention, the power steering input signal repeatedly repeated due to the slight handling of the driver is discriminated as a normal signal, Air amount compensation is performed to perform a certain amount of fuel compensation, thereby preventing the engine from being stalled and stopped.

While the present invention has been particularly shown and described with reference to exemplary embodiments thereof, it is to be understood that the invention is not limited to the disclosed exemplary embodiments, but, on the contrary, It will be understood by those skilled in the art that various changes in form and details may be made therein without departing from the spirit and scope of the invention as defined by the appended claims.
