Recent developments in vehicles focus on emissions regulations and fuel economy, and vehicle drivers also tend to choose vehicles with higher fuel consumption.

Accordingly, automobile manufacturers use an idle stop and go (ISG) function to stop the engine when idling occurs over a certain period of time or to stop the vehicle when the vehicle is idling and to restart the vehicle at the driver's departure point.

The hydraulic pressure in the automatic transmission can not be formed in the case of the automatic transmission or the oil pump of the continuously variable transmission at the time of stopping the engine, the proper line pressure is not maintained and the clutch or brake that forms the gear in the automatic transmission can not be operated. A shift shock occurs.

That is, in the ISG system according to the related art, an electric oil pump other than a mechanical oil pump is additionally installed to prevent a shift shock due to a sudden supply of hydraulic pressure when the engine is restarted.

In the case of such an electric oil pump, an appropriate line pressure is formed even when the engine is stopped, thereby preventing a shift shock caused by restarting.

However, the ISG system according to the related art requires additional external hydraulic line and exhaust line to additionally install the external electric oil pump and supply the generated hydraulic pressure to the automatic transmission. Therefore, the additional component, structure complexity, and cost increase And the like.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Hereinafter, an ISG control apparatus and method for a vehicle according to the present invention will be described in detail with reference to the accompanying drawings.

1 is a block diagram of an ISG control apparatus for a vehicle according to the present invention.

1, a vehicle ISG control apparatus includes a GPS receiving unit 110, a speed detecting unit 120, a torque detecting unit 130, a turn signal lamp detecting unit 140, a control unit 150, a communication unit 160, A starting device 170, and an electronic parking brake device 180.

The communication unit 160 may include a traffic control center 200 for performing V2I communication wirelessly with the communication unit 160 installed in the vehicle. Here, the traffic control center 200 may be a remote intelligent traffic system.

When the ISG mode is selected by the user, the GPS receiver 110 receives overall information on the road conditions such as vehicle position information, vehicle speed information, and road map information from the GPS according to the control of the controller 150, (150). Here, although not shown in the drawing, a mode selection button may be used for selecting the ISG mode. Various information received through the GPS receiving unit 110 may be received even if the ISG mode is not selected, and information received for application to a navigation system of an existing vehicle system may be used.

The speed detector 120 may detect the current speed of the vehicle using a speed sensor mounted on the vehicle and provide the detected speed information of the vehicle to the controller 150. [ Here, the speed of the vehicle and the vehicle speed information received through the GPS receiver 110 may also be used.

The torque detector 130 detects the torque of the vehicle using various sensors mounted on the vehicle and provides the detected torque information of the vehicle to the controller 150.

When the ISG mode is selected by the driver, the turn signal indicator detector 140 detects whether the turn signal lamp is turned on under the control of the controller 150, and provides the detected signal to the controller 150.

The communication unit 160 is wirelessly connected to the traffic control center through the V2I communication under the control of the control unit 150 according to the ISG mode selection and receives the traffic light information on the traveling road from the traffic control center 200 ), Traffic light change time information, and the like to the control unit 150.

The control unit 150 controls the starting device 170 and the electronic parking brake device 180 according to various information and detection signals provided from the respective devices to perform the ISG function.

Hereinafter, a specific operation of the control unit 150 will be described.

First, it is determined whether or not the ISG mode is selected while the vehicle is running, though it is not shown in the figure.

When the ISG mode is selected, the control unit 150 calculates the distance to the stop line of the intersection using the vehicle position information and the road map information received from the GPS receiving unit 110.

The control unit 150 determines whether the calculated distance to the stop line is less than a predetermined threshold distance and determines whether the direction indicator is turned on when the calculated distance is less than the threshold distance, Signal. Here, the case where the calculated distance is smaller than the critical distance may mean that the distance to the stop line of the intersection is approaching.

When the turn signal lamp is on, the control unit 150 controls the communication unit 160 to transmit the signal lamp information, the signal lamp change time information, such as a stop signal, from the remote traffic control center 200 via the V2I communication Time required until the signal is changed to the signal, time information required for changing from the start signal to the stop signal, and the like.

The communication unit 160 receiving this information provides the corresponding information to the controller 150. [

The control unit 160 determines whether the signal lamp in the current intersection is a stop signal by using the signal lamp information received through the communication unit 160.

If the signal is a stop signal, the control unit 150 changes the stop signal of the signal lamp to the start signal using the signal change time information signal wirelessly received from the traffic control center 200 through the communication unit 160 And compares the required time with the set time.

Meanwhile, when the signal lamp in the intersection is the start signal using the signal lamp information received through the communication unit 160, the time required from the start signal to the stop time is calculated, and the calculated time is compared with the set time.

As a result of the comparison, if the time required until the start signal is changed to the start signal is greater than the set time, that is, the change time from the stop signal to the start signal remains for a predetermined time or more, The control unit 150 can control the driving force from the current position to the stop line using the vehicle speed, torque, and road surface gradient information received through the speed detecting unit 120, the torque detecting unit 130, and the GPS receiving unit 110 Calculate the distance perception.

Meanwhile, when the time required until the start signal is changed from the start signal to the stop signal is shorter than the set time, that is, the control unit 150 changes the signal lamp to the stop signal before passing through the intersection, The control unit 150 calculates the target driving distance from the current position to the stop line using the vehicle speed, torque, and road surface gradient information as described above.

If the calculated distance is a distance at which the engine can be started by turning off the engine, the control unit 150 controls the starting device 170 to turn off the engine and perform driving.

After driving, the controller 150 determines whether the vehicle is stopped using the speed of the vehicle provided by the speed detector 120. If the vehicle is stopped, the controller 150 controls the electronic parking brake device 180, To control the vehicle so that it does not move regardless of the road surface gradient. Here, the reason for turning on the electronic parking brake is to prevent the forward and backward braking due to the environment of the road on which the vehicle is stopped.

On the other hand, after turning on the electronic parking brake, the control unit 150 controls the electronic parking brake to change from the stop signal of the traffic light to the start signal using the traffic light change time information wirelessly received from the traffic control center 200 through the communication unit 160 If the time required to change to the start signal is shorter than the set reference time, that is, if the signal lamp is expected to be changed to the start signal within a short time, the distance from the vehicle to the stop line Thereby calculating the vehicle restart time. Here, the reason for calculating the restart time is that if the vehicle is located in front of the stop line, the vehicle can be immediately restarted, but the vehicle may stop at a position a certain distance from the stop line. In other words, there are cases where other vehicles stop between the car and the stop line.

When the vehicle restart time is calculated according to the distance from the vehicle to the stop line, the controller 150 calculates a sum of the calculated time and the time required to change the start signal according to the signal change time information received through the communication unit 160 The control unit 150 controls the starting device 170 so that the starting time of the starting device 170 is shorter than the predetermined time, And the engine start is turned on.

After turning on the engine, the electronic puck brake device 180 is controlled to release the electronic parking brake to start the vehicle so that the vehicle can be started according to the change to the start signal.

If the sum of the restart time calculated according to the distance from the vehicle to the stop line and the change time required to change the start signal according to the signal change time information received through the communication unit 160 is greater than the preset time, Is changed to the start signal but the other vehicles are located in the front of the vehicle and the distance to the stop line is more than a certain distance, the engine start is kept open for the time required from the departure of the preceding vehicle to the departure of the vehicle .

In summary, when the vehicle is stopped at a position close to the stop line in the state that the engine is turned off, the engine start and the parking brake are released at the same time as the start signal is changed, If the distance to the vehicle is more than a certain distance, that is, if other vehicles are stopped in front of the vehicle, the vehicle must start after the departure of the squad cars. Therefore, even if the signal is changed to the start signal, As shown in FIG.

Hereinafter, an ISG control method for a vehicle according to the present invention, which corresponds to the operation of the ISG control apparatus of the vehicle according to the present invention, will be described step by step with reference to FIGS. 2A to 2C.

FIGS. 2A to 2C are flowcharts of an ISG control method for a vehicle according to the present invention.

First, as shown in FIG. 2A, it is determined whether the ISG mode is selected while the vehicle is running (S101).

When the ISG mode is selected, the vehicle position information, vehicle speed information, and road map information are received from the GPS module (S102).

In step S103, a distance S1 to the stop line of the intersection is calculated using the vehicle position information, the vehicle speed information, and the road map information received from the GPS module (S103). Here, it should be understood that the vehicle speed information can be acquired through the GPS module, but also through the vehicle speed sensor of the vehicle.

Next, it is determined whether the distance S1 to the calculated stop line is smaller than a predetermined threshold distance (S104).

As a result of the determination, if the distance S1 to the calculated stop line is smaller than the critical distance, it is determined whether the turn signal lamp is turned on by the driver (S105). Here, the case where the calculated distance S1 to the stop line is smaller than the critical distance may mean that the distance to the stop line of the intersection is approaching.

As a result of the determination in step S105, if the turn signal lamp is turned on, it is possible to change the signal light information, the signal light change time information, for example, from the stop signal to the start signal wirelessly via the V2I communication from the remote traffic control center (intelligent traffic system) Time required until the signal is changed from the start signal to the stop signal, and the like are received (S106).

Next, as shown in FIG. 2B, in step S106, it is determined whether the traffic light in the current intersection is a stop signal using the traffic light information received wirelessly from the intelligent traffic system (S107).

As a result of the determination, if the corresponding signal is a stop signal, it calculates the time required (T1) from the stop signal of the signal lamp to the start signal using the signal change time information signal wirelessly received from the intelligent traffic system in step S106 (S108).

Then, it is determined whether the time T1 required for changing the calculated stop signal to the start signal is greater than a predetermined reference time T ref1 (S110).

On the other hand, if it is determined in step S107 that the signal of the traffic light is a start signal other than the stop signal, the time T2 from the start signal to the stop time is calculated using the traffic light information received from the intelligent traffic system S109).

Subsequently, it is determined whether the time T2 required for changing the calculated start signal to the stop signal is shorter than a preset reference time T ref2 (S111)

As a result of the comparison in step S110, when the time T1 required for changing from the stop signal to the start signal is larger than the reference time T ref1 , that is, when the change time from the stop signal to the start signal is constant If it is determined that the time required for driving the vehicle is long, it is checked whether the distance from the current position to the stop line is a distance at which the driving force is possible by using the vehicle speed, torque, and road surface gradient information (S112).

On the other hand, if it is determined in step S111 that the time T2 required to change from the start signal to the stop signal is smaller than the reference time T ref2 , that is, not passing the intersection, If the signal lamp is a short time before the stop signal is changed, the driver checks whether the distance from the current position to the stop line is a distance at which the vehicle can travel by using the vehicle speed, torque, and road surface gradient information (S112).

Next, as a result of the check in step S112, it is determined whether the distance from the stop line to the stop line is sufficient to allow the vehicle to travel by the force (S113).

As a result of the determination, when the engine is turned off to the stop line and the distance is not the distance that the vehicle can travel by the force of the vehicle, the vehicle is driven in the state where the engine is maintained as it is. (S114), control is performed so as to perform the driving of the vehicle.

Next, as shown in FIG. 2C, it is determined whether the vehicle is stopped using the speed information of the vehicle after driving the vehicle (S115).

As a result of the determination, if the vehicle is stopped, the electronic parking brake is turned on (S116) to control the vehicle so as not to move regardless of the road surface gradient. Here, the reason for turning on the electronic parking brake is to prevent the forward and backward braking due to the environment of the road on which the vehicle is stopped.

On the other hand, after turning on the electronic parking brake, the time required to change from the stop signal of the traffic light to the start signal is compared with the set reference time using the traffic light change time information wirelessly received from the intelligent traffic system, Is smaller than the set reference time (S117).

As a result of the determination, when the time required until the start signal is changed is smaller than the set reference time, that is, when the signal lamp is expected to be changed into the start signal within a short time, the vehicle restart time according to the distance from the vehicle to the stop line is calculated (S118). Here, the reason for calculating the restart time is that if the vehicle is immediately positioned on the stop line, the vehicle can be immediately restarted, but the vehicle may stop at a position a certain distance from the stop line. In other words, there may be other vehicles parked between the car and the stop line.

When the calculated time is longer than the predetermined time, the time required to change the start signal according to the traffic light change time information received from the intelligent traffic system is smaller than the predetermined time (S119).

As a result of the determination, if the calculated time and the time required for changing the start signal according to the signal change time information received from the intelligent traffic system are less than a predetermined time, i.e., the distance to the stop line is shorter If it is the time to turn on the engine start of the vehicle within the time, the engine starting is controlled by controlling the starter (S120).

After the engine is turned on, the electronic parking brake is released to start the vehicle (S121) so that the vehicle can start in response to the change to the start signal.

If it is determined in step S119 that the sum of the restart time calculated based on the distance from the vehicle to the stop line and the change time to the start signal according to the traffic light change time information received from the intelligent traffic system is less than a predetermined time If the signal light is changed to the start signal but the other vehicles are located in front of the vehicle and the distance to the stop line is more than a certain distance, the engine start is turned off by the time required from the departure of the preceding vehicle to the departure of the vehicle State.

In summary, when the vehicle is stopped at a position close to the stop line while the engine is in the off-state, the engine start and the parking brake are released at the same time as the start signal is changed, If the distance of the vehicle is more than a certain distance, that is, if other vehicles are stopped in front of the vehicle, the vehicle must start after the departure of the preceding vehicles. Therefore, even if the signal is changed to the start signal, Release.
