Description

BACKGROUND OF THE INVENTION 1. Field of the Invention [0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a vehicle control apparatus and method, and more particularly, to a vehicle control apparatus and method capable of protecting a power train when a driver operates a shift lever in a P-stage during driving.

As is known, an automatic transmission is a transmission that automatically implements an appropriate gear stage (speed change stage) based on variables related to vehicle driving such as vehicle speed and throttle opening amount.

A shift lever for specifying a gear shift range such as P (parking), R (reverse), N (neutral), D (running), +, -, etc. is connected to the automatic transmission for a vehicle , The shift lever is a rod that connects the transmission with the driver's operation for gear shifting and is also referred to as a transmission gear shift lever (TGS).

The position of the manual valve of the automatic transmission is determined by the operation of the shift lever, and an appropriate hydraulic pressure supply line is formed according to the position of the shift lever. The position of the manual valve is detected by an inhibitor switch, A transmission control unit (hereinafter referred to as " TCU ").

Therefore, the TCU controls the hydraulic system of the automatic transmission so that an appropriate gear is established in the driving mode designated by the driver.

When the automatic shift control is provided with a manual up (+) / down (-) function, the shift position of the shift lever is controlled by the CAN And transmitted to the TCU through communication to control the shifting to the corresponding target gear stage.

The shift lever of the automatic transmission usually displays the position of the shift lever, such as P, R, N, D, in the character portion of the PRND indicator with the light to visually inform the driver of the position of the shift lever.

1 shows an example of a straight type in which the shift lever can be moved to any one of the positions P, R, N, and D by operating only the front and rear straight lines without operating the left and right shifts of the shift lever 1 as one of the shift types of the shift lever. Giving.

In this straight type shift lever structure, shifting is possible when the driver operates the button (not shown) of the shift lever 1 without operating the brake pedal while the vehicle is running.

In particular, it is possible for the driver to move the position of the shift lever 1 from the driving end (D-stage or R-end) to the P-end during driving of the vehicle. Normally, the driver depresses the brake pedal to decelerate the vehicle, It should be moved.

However, before the vehicle is decelerated, the shift lever 1 can be operated to the P-stage position. Thus, during the forced P-stage assembly during running of the vehicle, noise and shock may be generated in the gear portion of the transmission. The driver may feel anxiety.

Particularly, when the vehicle moves from a state in which the speed of the vehicle is high to the P stage, a shock is applied to a power train (PT) such as an engine and a transmission.

SUMMARY OF THE INVENTION Accordingly, the present invention has been made in view of the above problems, and it is an object of the present invention to provide a control apparatus and a control method thereof, which are capable of protecting a power train when a driver operates a shift lever in a P stage before a vehicle is stopped, And to provide a vehicle control apparatus and method capable of solving the problem of the vehicle.

2 is a block diagram showing a configuration of a vehicle control apparatus according to an embodiment of the present invention.
3 is a flowchart showing a vehicle control method according to an embodiment of the present invention.

Hereinafter, exemplary embodiments of the present invention will be described in detail with reference to the accompanying drawings, which will be readily apparent to those skilled in the art to which the present invention pertains.

The present invention protects the power train when the driver manipulates the shift lever in the P-stage at the input of the P-speed change by the driver during the driving of the vehicle, that is, before the vehicle is stopped. In addition, the problem of noise and shock generation, The present invention relates to a vehicle control apparatus and method capable of solving the above problems.

2 is a block diagram showing the configuration of a vehicle control apparatus according to an embodiment of the present invention. As shown in the figure, the shift lever detection section 11, the vehicle speed detection section 12, the brake pedal detection section 13, the shift control unit TCU ) 21, a braking control unit 22, a transmission 31, and a braking device 32.

In the present invention, the shift control unit 21 and the braking control unit 22 perform the vehicle control for protecting the power train during the P-step shift input during the running of the vehicle through the cooperative control.

In the above configuration, the shift lever detecting portion 11 is for detecting the position of the shift lever (1 in Fig. 1) operated by the driver, that is, the range selection position of the shift lever, Can be a switch.

The shift lever detector 11 detects the position of the shift lever operated by the driver when the driver operates the shift lever and outputs an electric signal indicating the position of the shift lever, that is, the shift lever position signal to the shift control unit 21, .

For example, when the shift lever is operated and moved to the P-stage by the driver when the shift lever is located at the D-stage or R-stage, which is the travel stage, the shift lever detection portion 11 indicates the shift lever P- The transmission control unit 21 outputs an electric signal to the shift control unit 21 so that the shift control unit 21 recognizes the P shift operation by the driver.

At this time, although not shown, the shift control unit 21 transmits a P-stage input signal, that is, a shift lever position signal indicating that the shift lever is operated to the P-stage, to the braking control unit 22 through communication.

The vehicle speed detector 12 detects a running vehicle speed of the vehicle and can be a wheel speed sensor and transmits a vehicle speed signal indicative of the current vehicle speed to the braking control unit 22 through communication.

The brake pedal detection unit 13 detects the brake pedal operation state when the driver depresses the brake pedal, and transmits a brake pedal operation signal to the braking control unit 22 through communication.

The brake pedal detecting unit 13 may be a brake pedal switch (BLS) provided to detect a brake pedal operation in a normal vehicle.

The transmission control unit 21 outputs a control signal for controlling the transmission 31 on the basis of the signal from the shift lever detector 11 and the braking control unit 22 transmits the control signal to the transmission control unit 21, And outputs a control signal for controlling the braking device 32 on the basis of the input P-phase input signal and the vehicle speed signal of the vehicle speed detector 12. [

In the present invention, the braking control unit 22 determines the deceleration (D) for braking the vehicle from the vehicle speed information detected by the vehicle speed detector 12, determines the target braking force according to the determined deceleration , And outputs a control signal for generating the target braking force.

Accordingly, the braking device 32 generates the braking force in accordance with the control signal output from the braking control unit 22, thereby decelerating and braking the vehicle.

Here, the braking control unit 22 and the braking device 32 may be a known electronic braking system or an ESC (Electronic Stability Control) system.

In the ESC system, the ESC controller corresponds to a braking control unit. The braking device includes a hydraulic circuit that generates a hydraulic pressure required for generating a braking force in accordance with a control signal output from the ESC controller, and a hydraulic circuit And a wheel brake that generates a braking force to the vehicle wheel.

The braking control unit 22 determines a target braking force in accordance with the deceleration and outputs a control signal for controlling the hydraulic circuit so that the hydraulic pressure satisfying the determined target braking force is generated.

Further, in the braking device 32, the components in the hydraulic circuit operate according to the control signal output from the braking control unit 22 to generate the hydraulic pressure, and the braking force is generated by the generated hydraulic pressure.

Since the process of determining the target braking force from the deceleration and the process of generating the hydraulic pressure to generate the target braking force when the deceleration is determined in this way are not different from each other in comparison with the normal braking control process, It will be omitted.

FIG. 3 is a flowchart showing a vehicle control method according to an embodiment of the present invention. Referring to FIG. 3, a control process for protecting a power train during a P-step shift input by a driver while driving the vehicle will be described.

First, after the IG on, the shift control unit 21 determines whether or not the position of the shift lever detected by the shift lever detector 11, that is, the current gear position (shift position) of the transmission 31 as the shift lever is operated (S11, S12). If the current gear position is the D-stage or the R-position, the shift lever position signal corresponding to the D-stage or R-stage is determined To the braking control unit (22).

Of course, the gear stage of the transmission 31 at this time is a D-stage or R-stage.

Following the braking control unit 22 is D-range or the received R-stage inputs the vehicle speed signal from the vehicle speed detector 12 in a state the vehicle speed detector 12, the current travel speed (V 0) of the detection by the set vehicle speed 1 ( (S13), and monitors whether the brake pedal operation signal indicating that the brake pedal is operated by the driver is input from the brake pedal detection unit 13 in a state where the set vehicle speed is 1 or more (S14 ).

Then, when the driver operates the shift lever to the P-stage position in a state where the set vehicle speed is 1 or more and the brake pedal operation signal is not inputted, the shift control unit 21 detects this through the shift lever detecting portion 11 (S15). Further, a shift lever position signal indicating that the shift lever is operated in the P-stage, that is, a P-stage input signal, is transmitted to the braking control unit 22. [

The braking control unit 22 requests the shift control unit 21 to change to the Nth stage and the shift control unit 21 sets the gear stage of the transmission 31 in response to the request of the braking control unit 22. [ To the N stage (neutral) (S16).

Following the braking control unit 22 is a vehicle speed detecting section 12 and (S17), the current vehicle speed (V 0) of the current travel speed (V 0) of the detection compared with the set vehicle speed 2 by the set vehicle speed 2 (for example, per hour 30 km / h), a control signal for generating a braking force corresponding to a predetermined deceleration (for example, 0.4 g) is output (S18).

Accordingly, the braking device 32 generates the braking hydraulic pressure in accordance with the control signal output from the braking control unit 22, and the braking force is generated by the braking hydraulic pressure, thereby decelerating the vehicle.

In the state where the vehicle speed exceeds the set vehicle speed 2 after the P-stage input as described above, the vehicle is controlled to be decelerated at a predetermined deceleration to shorten the braking distance and the braking time.

Thereafter, when the vehicle decelerates and decelerates at a set deceleration, the braking control unit 22 performs braking control for each vehicle speed for vehicle deceleration in order to prevent driver discomfort due to braking (S19).

That is, the deceleration is calculated using the current running vehicle speed detected by the vehicle speed detector 12 in real time, and the braking force is generated to generate the braking force in accordance with the calculated deceleration.

At this time, the deceleration can be obtained from the current vehicle speed and the target vehicle speed, and the target vehicle speed can be obtained from the current vehicle speed.

For example, the target vehicle speed can be set to be determined as the vehicle speed corresponding to 50% of the current vehicle speed (target vehicle speed = current vehicle speed x 0.5).

At this time, it can be set to be obtained from the following equation (1) using the arrival time preset to the current vehicle speed and the target vehicle speed together with the current vehicle speed and the target vehicle speed.

[Equation 1]

D = (V t - V 0 ) / t

Here, D represents deceleration, V t represents the target vehicle speed, V 0 represents the current vehicle speed, and t represents the arrival time, and the arrival time may be set to, for example, 1 second.

When the current running vehicle speed becomes equal to or lower than the set speed 3 (for example, 4 km / h) by performing the braking control according to the vehicle speed as described above, the braking control for decelerating the vehicle is terminated so that the vehicle can stop by itself without generating braking force S20, S21).

When the vehicle reaches the stop state, that is, when the vehicle is fully braked (V 0 = 0 km / h), the braking control unit 22 causes the shift control unit 21 to stop the transmission 31 Control is performed to change the gear position from the N-stage (neutral) to the P-stage (S22, S23).

As described above, according to the present invention, even if the driver moves the shift lever to the P-stage position before the vehicle stops, the gear stage is changed to the P-stage desired by the driver after the vehicle is stopped. It is possible to protect the power train components such as the engine and the transmission as well as the shock.

The present invention is not limited to this, and one integrated control unit for performing the shift control and the braking control of the vehicle may be applied to the shift lever of the shift lever detecting unit, The brake pedal operation signal of the brake pedal detecting unit, and the vehicle speed signal of the vehicle speed detecting unit, and performs the control process described above.

While the present invention has been particularly shown and described with reference to exemplary embodiments thereof, it is to be understood that the scope of the present invention is not limited to the disclosed exemplary embodiments. Forms are also included within the scope of the present invention.
