[Field of Invention]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an overtaking acceleration control apparatus and a control method thereof for an automatic transmission-mounted vehicle, and more particularly, to increase and decrease the speed of the shift control unit by turning on the acceleration switch so that the transmission control unit recognizes an electrical signal. The present invention relates to an automatic transmission-mounted vehicle overtaking acceleration control device for controlling the overtaking acceleration of a vehicle and a control method thereof.

[Private Technology]

In general, in order to accelerate the vehicle in the vehicle equipped with an automatic transmission, when the accelerator pedal is accelerated at the fourth speed in the D range, the transmission unit automatically shifts to the lower speed by three speeds or accelerates. (Operation), the overdrive switch is turned off in the D range or downshifted in the second range, and the accelerator pedal is opened by pressing the accelerator pedal to accelerate and pass.

In the prior art, the overtaking acceleration method of a vehicle equipped with an automatic transmission is designed for a shifting feeling (smooth shifting feeling) at the time of shifting rather than the responsiveness of the shifting, so that the rapid overtaking, that is, the rapid overtaking acceleration is not performed at the time when the rapid acceleration is required. There is a problem.

In addition, it is troublesome to return the shift lever to the D range again after passing.

Further, in addition to the above method, the method of accelerating overtaking after the downshift is automatically performed by the transmission control unit from the fourth speed to the third speed travel has a problem that the response is slow as in the downshift operation by the shift lever.

In addition, there is a problem in that a shift of the shift feeling and a shift lever operation miss may occur during the acceleration of overtaking due to the driver's operation of the uniform shift or the manual shift by the shift lever according to the prior art.

In step conversely, if greater, proceeding to the next mode step;

EXAMPLE

Hereinafter, with reference to the accompanying drawings a preferred embodiment of the present invention will be described in more detail.

1 is a diagram schematically showing that the overtaking acceleration switch according to the present invention is connected and installed, wherein reference numeral 1 denotes an acceleration switch.

The acceleration switch 1 is connected to the transmission control unit 2 that controls the automatic transmission so that the driver can operate the driver when the driver wants to pass while driving.

The transmission control unit 2 detects the operation of the acceleration switch 1 by an electrical signal, and detects the driving speed of the vehicle by the vehicle speed sensor 3 and the throttle position sensor (TPS) 4. By detecting the opening degree of the throttle valve by.

Then, when the vehicle speed sensor 3 and the throttle position sensor 4 detect the driving state of the vehicle and detect the signal of the acceleration switch 1, the transmission control unit 2 shifts to the lower stage. This is done first, and then the electric pressure control solenoid valve (PSCV) (5) and the shift control solenoid valve-A (6) or the shift control solenoid valve-B (7) related to the shifting are carried out so that the shift is performed in the normal shift mode. It operates by applying a positive signal.

Referring to the flow chart illustrating a method for accelerating the overtaking of a vehicle with an automatic transmission according to the present invention, an acceleration switch operated when a driver attempts to overtake while driving in a start step S10 of driving a vehicle equipped with an automatic transmission is driven. The transmission control unit (2) detects the operation.

Accordingly, when the transmission control unit 2 detects the non-operation of the acceleration switch 1, the transmission control unit 2 proceeds to the start step S10, and when determining the operation (S20), proceeds to the next step.

After determining the operation of the acceleration switch 1 (S20) and then detecting the current shift stage and the current vehicle speed, if the opening angle of the throttle valve is not large, it is determined as the start step (S10), and the largeness (S30). I'm going to go through the steps.

Accordingly, when the opening angle of the throttle valve is larger than a predetermined value set as a function of the current shift stage and the vehicle speed, the shift from the current shift stage to the low stage is made in step S40.

In addition, when the shift is made from the current shift stage to the lower stage, the sum of the vehicle speeds at the start of the shift, which is added to the opening angle of the throttle valve, the increment of the vehicle speed set by the current shift stage and the current vehicle speed, is greater than the current vehicle speed. If it is determined in step S50 that it is not large, the process shifts to the next step of maintaining the current speed change stage (S40).

If it is determined in step S50 that the current vehicle speed is large, the process returns to the normal shift mode step S60 in which shifting is performed by the shift path to proceed.

As described above, the step of completing the overtaking acceleration control method for driving in the state in which the overtaking acceleration is returned to the normal shift mode step S60 is completed (S70).

According to the operation of the present invention as described above, when the driver operates only the acceleration switch 1 when the vehicle is equipped with the automatic transmission, the transmission control unit 2 detects the current vehicle speed and the current gear stage. When the operation signal of the acceleration switch 1 is detected, the pressure control solenoid valve (PSCV) (5) and the shift control solenoid valve-A (6) or the shift control solenoid valve-B (7), etc. Will be activated.

At this time, if the current throttle valve opening angle is smaller than the preset throttle valve opening angle to reflect the driver's intention to accelerate at the current shift stage and the vehicle speed, the process proceeds to the first step S10 again.

After the transmission control unit 2 detects the current vehicle speed and the current shift stage, the current throttle valve opening angle is set to a predetermined throttle valve opening angle that reflects the driver's intention to accelerate at the current shift stage and the vehicle speed. If it is determined that the greater (S30), that is, the transmission control unit (2) is determined that the driver wants a sudden acceleration, the speed is shifted to the lower stage so that the overtaking acceleration is made. (S40)

The shift to the lower stage by the transmission control unit 2 is performed by the pressure control solenoid valve (PSCV) 5 and the shift control solenoid valve-A (6) or the shift control solenoid valve-B ( 7) is carried out because the transmission control unit 2 operates.

Accordingly, when overtaking acceleration is performed while driving the vehicle, the transmission control unit 2 detects the current throttle valve opening angle, the shift stage, and the vehicle speed, and adds it to the vehicle speed at the start of the shift and the increment value required in this state. If the current vehicle speed is not large, maintain the current shift speed.

Otherwise, if the current vehicle speed is large, the transmission control unit 2 operates the valves related to the shift, thereby shifting by the shift path, that is, returning to the normal shift mode (S60), thereby completing the overtaking acceleration control method. (S70).

The present invention has an effect of obtaining a rapid overtaking acceleration because the overtaking acceleration is made by the pressing operation of the acceleration switch, and the shift at this time is designed to give priority to the response.

In addition, if the vehicle speed increases by a certain amount when downshifting the shift lever due to the overtaking acceleration, the vehicle shifts back to the normal shift mode, thereby eliminating the need to reposition the shift lever.
