Here, as is well known, the LPI system refers to a technique of liquefying LPG fuel at high pressure and injecting the LPG fuel liquefied at high pressure by cylinder using an injector. In addition, the LPi lamp 60 is a lamp that is turned on when the LPG fuel in the fuel line is in the gaseous state and is turned off in the liquid state (or vice versa). In other words, LPG vehicles equipped with LPI systems can be started at initial start-up after a period of time for fuel pressure to build up in the fuel line (i.e., the time for the fuel to convert from gas to liquid).

In addition, the vehicle control apparatus according to the present invention may be connected to the pressure sensor 65 for detecting the bus negative pressure (air brake pressure) when installed in the bus.

In addition, the vehicle control apparatus according to the present invention, when installed in a manual gear shift vehicle, may be connected to the clutch sensor 70 for detecting whether the clutch pedal is stepped on.

In addition, the ST wire connects the battery and the starter motor when the car key is in the third stage (START).

The solenoid valve 90 prevents the vehicle from slipping by maintaining the pressure applied to the wheel cylinders when the vehicle is stopped on an incline or the like, regardless of whether the brake pedal is stepped on. It will be described in detail.

2 is a block diagram of a hydraulic control system using a solenoid valve.

As shown in FIG. 2, a hydraulic control system using a solenoid valve includes a master cylinder 460 for generating hydraulic pressure by the operation of a brake pedal, and a wheel cylinder 410 installed at each wheel to brake each wheel by hydraulic pressure. ), Two hydraulic lines 440 and 450 connecting the master cylinder 460 and the wheel cylinder 410, and are installed in the hydraulic lines 440 and 450 between the master cylinder 460 and the wheel cylinder 410. ABS control unit 420 to collectively control the operation of the ABS actuator 430, ABS actuator 430 to intermittently control the pressure transmitted to the wheel cylinder 410 to prevent slip (slip) during the braking of the vehicle, It may include a solenoid valve 90 installed in each hydraulic line (440, 450) between the ABS actuator 430 and the master cylinder 460 and the vehicle control device 100 of the present invention.

On the other hand, the vehicle control apparatus 100 according to an embodiment of the present invention includes a drive module 110, a control module 120, a collection module 130, a storage module 140 and the RF module 150. Can be done.

In the above-described configuration, the driving module 110 is controlled by the control module 120, the switching unit 75, the door 80, the brake lamp 85, the solenoid valve 90, the buzzer (95), The head lamp 96, the generator 40, and the air conditioner 97 are driven.

The control module 120 inspects a signal input from the sensors and controls the driving module 110 based on the test result. In addition, the RF module 150 controls the driving module 110 based on the radio frequency signal received from the remote controller 200.

For example, the control module 120 controls the driving module 110 to start the engine when the RF module 150 wirelessly receives the start signal from the remote controller 200. That is, the control module 120 controls the driving module 110 to connect the ST wire and the IG1 wire to the battery so that the starting motor operates, and the fuel and air are supplied to the engine. Then, when the generator 40 is driven (that is, when a high signal is input from the generator 40), the driving module 110 is controlled to disconnect the ST wire from the battery and to disconnect the IG2 wire. To the battery.

In addition, when the control module 120 checks the signals input from the sensors, when it is determined that the user intends to start the vehicle with the steering wheel locked, that is, the car key is not or is not inserted into the key box. Even if the car key is not located at the first stage ACC, the driving module 110 is controlled to stop the engine driving. That is, the control module 120 controls the driving module 110 to turn off the start by disconnecting the connection between the battery and the IG1 wire and the connection between the battery and the IG2 wire. Furthermore, the control module 120 controls the driving module 100 to ring the buzzer 95. Here, ringing the buzzer 95 is to guide the user to unlock the steering wheel with the car key and start again.

In addition, the control module 120 is a signal input from the sensors after a predetermined warm-up time (for example, 3 minutes to 5 minutes) after the initial start-up (user refers to the first gun start to drive the vehicle) As a result of the test, when the vehicle is stopped and the voltage of the battery is greater than or equal to a predetermined reference value (for example, 12V), the driving module 110 is controlled to stop driving of the engine (Idle Stop). In this state, when a signal input from the sensors is inspected, when the voltage of the battery is equal to or less than a predetermined reference value or when the user determines that the user presses the accelerator pedal or after the engine is stopped by the driving module 110 in advance, When a predetermined time (for example, 4 minutes) has passed, the engine is controlled to start the engine by controlling the driving module 110 (Idle Start).

In addition, the control module 120 to perform the ISS as described above, when the user initially started the engine using the remote controller 200, while not performing when the engine is initially started using the car key. Can be programmed. The reason is to allow the user to choose whether or not to use the ISS. Furthermore, the control module 120 may be programmed to perform the ISS only when the RF module 150 wirelessly receives the ISS operation signal from the remote controller 200. To this end, the remote controller 200 may be provided with an ISS button for selecting whether to operate the ISS, so that the user can operate the ISS button to select whether to use the ISS while driving the vehicle. Of course, the ISS button as described above may also be provided in the vehicle. However, since the wiring work for connecting the vehicle control device 100 and the ISS button and the cost thereof are additionally required, the remote controller 200 may be used to select whether to operate the ISS.

In addition, the control module 120 may be programmed to perform the ISS even if the user does not initially start the engine using the remote controller 200. For example, the control module 120, when the user presses the brake pedal in a state in which the car key is located in the first stage (ACC) or the second stage (ON), and controls the drive module 110 to initially start the engine, as described above Perform the ISS. However, when the car key is located in the first stage to perform the ISS, while the car key is located in the second stage can be programmed not to perform the ISS. The reason is to allow the user to select whether or not to use the ISS as in the initial startup using the remote controller 200.

In addition, the control module 120 resumes driving of the engine, that is, stops driving of the engine within a predetermined time (for example, 20 seconds) after the engine starts the idle start, that is, the engine stops the idle. Shall not be made. The reason is that frequent ISS due to congestion causes the engine and battery to be overwhelmed, so it is advisable not to perform idle stop for at least 20 seconds after the engine restarts.

In addition, the control module 120 controls the driving module 110 when it is determined that the vehicle is traveling uphill by a predetermined angle (for example, 5 degrees) as a result of examining the signals input from the sensors. By stopping the driving of the generator 40 and the air conditioner 97, the fuel is saved. In this state, the driving of the generator 40 and the air conditioner 97 is resumed when a predetermined stop time (for example, two minutes) has elapsed after the driving of the generator and the air conditioner has stopped, or the vehicle has moved out of an uphill of a predetermined angle or more. Let's do it.

In addition, when the vehicle control apparatus 100 of the present invention is installed in a manual gear shifting vehicle, the control module 120 checks the signals input from the sensors, and as a result, the RPM is set to a predetermined reference value (eg, , 3000RPM) or more, the buzzer 95 is sounded by controlling the driving module 110. Here, the ringing of the buzzer 95 is to guide the user to shift the gear.

In addition, the control module 120 controls the driving module 110 to turn on the brake lamp 85 to guide the vehicle driver behind the vehicle that the vehicle is stopped at the idle stop.

In addition, the control module 120 controls the driving module 110 to turn off the head lamp 96 in order to reduce the consumption of battery power during idle stop.

In addition, the control module 120 controls the driving module 110 when the vehicle is stopped in the driving state, particularly when the vehicle is stopped at an uphill or higher than a predetermined angle as a result of the detection of the tilt sensor 35 to control the solenoid valve 90. Excitation of the coil (not shown) maintains the braking force regardless of whether the brake pedal is stepped on (this function is called 'auto brake'). In this state, when the intention of starting the vehicle is sensed, for example, when the accelerator pedal is pressed as a result of the sensing of the accelerator sensor 30, the driving module 110 is controlled to demagnetize the coil of the solenoid valve 90 to thereby activate the auto brake function. Release it.

The collection module 130 collects the number of times that the driving of the engine is resumed by the control module 120, that is, the number of ISS operations, and collects the mileage, travel time and fuel economy information from the sensors.

The storage module 140 stores the ISS data collected by the collection module.

The RF module 150 communicates wirelessly with the remote controller 200. Here, as shown in FIG. 1, the remote controller 200 may receive the ISS data received from the vehicle control apparatus 100 by the RF module 120 and the RF module 120 that are in wireless communication with the vehicle control apparatus 100. It includes a storage module 230 for storing, a display module 240 for displaying the ISS data, a key input module 250 for receiving a user's command, and a control module 210 for collectively controlling the remote controller. Can be.

When the start signal is wirelessly received from the remote controller 200 (step S11), the engine is started (step S13). Even if 10 seconds have passed since the start-up, the buzzer 95 sounds when the battery voltage is less than 12V. Here, the buzzer 95 sounds to inform the user that there is a problem with the battery.

Next, the signals input from the sensors are inspected to determine whether the user intends to start the vehicle and whether the steering wheel is locked (steps S15 and S17).

As a result of the determination in step S15 and step S17, when it is determined that the user intends to start the vehicle in the locked state, the engine is stopped (step S19) and the buzzer 95 is sounded. On the other hand, if it is determined that the user intends to start the vehicle while the steering wheel is released, the driving of the engine is not stopped.

When the engine is not stopped, that is, when the vehicle is in operation, the signals input from the sensors are examined to determine whether the brake pedal is stepped on, whether the vehicle is stopped, and the warm-up time (for example, 3 to 5 minutes). It is judged whether or not (step S21, step S23 and step S25). In addition, it is determined whether other idle stop conditions are satisfied (step S27). For example, whether the voltage of the battery is above a predetermined reference value (e.g., 12V), is driving downhill above a predetermined angle (e.g., 5 degrees), whether the accelerator pedal is stepped, whether the gear is in the N state, and after restarting the engine It is determined whether a predetermined time (eg, 20 seconds) has elapsed.

As a result of the determination in steps S21 to S27, the brake pedal is in a depressed state, the vehicle is stopped, the warm-up time has elapsed, the battery voltage is 12V or more, no driving downhill of 5 degrees or more, and the accelerator pedal is not depressed. If the gear is in the N state and 20 seconds have elapsed since the engine was restarted, the engine is stopped (step S29).

Next, it is determined whether the idle start condition is satisfied in the idle stop state (step S31). For example, it is determined whether the voltage of the battery is less than or equal to a predetermined reference value (eg, 12V), whether the accelerator pedal is pressed, whether the clutch pedal is pressed, or whether a predetermined time (eg, 4 minutes) has passed after the idle stop.

As a result of the determination in step S31, when the battery voltage is 12V or less, the accelerator pedal or the clutch pedal is stepped on, or four minutes have elapsed after the idle stop, the engine driving is resumed (step S33). If the battery voltage is less than 12V even after 10 seconds after the engine restarts, the buzzer 95 sounds.

4 is a flowchart illustrating a vehicle control method according to another exemplary embodiment of the present disclosure, and unless otherwise described, the vehicle control apparatus 100 performs the subject.

When the start signal is wirelessly received from the remote controller 200 (step S41), the engine is started (step S43). Even if 10 seconds have passed since the start-up, the buzzer 95 sounds when the battery voltage is less than 12V.

Next, the signals input from the sensors are examined to determine whether the user intends to start the vehicle and whether the steering wheel is locked (steps S45 and S47).

As a result of the determination in steps S45 and S47, when it is determined that the user is about to start the vehicle in the state where the steering wheel is locked, the engine is stopped (step S49) and the buzzer 95 is sounded. On the other hand, if it is determined that the user intends to start the vehicle while the steering wheel is released, the ISS is performed without stopping the engine.

Next, the ISS data including the idle stop / start count, travel distance / time and fuel economy is collected (step S51), and the collected ISS data is stored (step S53).

On the other hand, when there is a request for ISS data from the remote controller 200 (step S55), the stored ISS data is wirelessly transmitted to the remote controller 200 (step S57). Then, the remote controller 200 wirelessly transmits, for example, the ISS data received from the vehicle control apparatus 100 to a management server (not shown) that manages bus operation. In addition, the vehicle control apparatus 100 of the present invention may transmit ISS data to an SD card (flash memory card) 300 or the like, as shown in FIG. 1. For example, when the SD card 300 is connected to the USB terminal provided in the vehicle, the vehicle control apparatus 100 recognizes this and transmits the ISS data to the SD card 300.

FIG. 5 is a flowchart illustrating a vehicle control method according to another exemplary embodiment of the present invention. Unless otherwise described, the vehicle control apparatus 100 performs the subject.

When the start signal is wirelessly received from the remote controller 200 (step S61), the engine is started (step S63).

Next, the signals input from the sensors are inspected to determine whether the user intends to start the vehicle and whether the steering wheel is locked (steps S65 and S67).

As a result of the determination in steps S65 and S67, when it is determined that the user is about to start the vehicle in the state where the steering wheel is locked, the engine is stopped (step S69) and the buzzer 95 is sounded. On the other hand, if it is determined that the user intends to start the vehicle while the steering wheel is released, the engine is not stopped.

It is determined whether the vehicle travels uphill by a predetermined angle (for example, 5 degrees) by checking signals input from the tilt sensors while the engine is not stopped, that is, while the vehicle is running (step S71). .

As a result of the determination in step S71, when it is confirmed that the vehicle is traveling uphill of 5 degrees or more, the driving of the generator 40 and the air conditioner 94 is stopped (step S73).

In this state, after stopping the driving of the generator 40 and the air conditioner 94, it is determined whether a predetermined stop time (for example, two minutes) has elapsed and whether the vehicle has left the uphill of 5 degrees or more (step S75). .

As a result of the determination in step S75, when two minutes have elapsed or have climbed 5 degrees or more, the driving of the generator 40 and the air conditioner 94 is resumed (step S77).

Next, after restarting the drive of the generator 40 and the air conditioner 94, it is determined whether the regenerative braking time (for example, 2 minutes) has elapsed (step S79).

As a result of the determination in step S79, when 2 minutes of the regenerative braking time elapses, the process returns to step S71.
