Description

CONTROL APPARATUS FOR VEHICLE {CONTROL APPARATUS FOR VEHICLE}

The present invention relates to a control device for a vehicle, and more particularly, to a technique for protecting an infant inside a vehicle in a runner state.

In the case of using a vehicle, there are often situations in which infants are left in the vehicle due to the lack of personality or attention, or inevitability or circumstances of the parents. This situation can cause big problems, especially in summer.

The human body is fragile enough to die when the temperature rises above 40 degrees, causing cells to die by heat.

By the way, the temperature inside the vehicle in the middle of summer may rise to 90 degrees in a short time (for example, 5 minutes). In such a situation, if the infant is prevented in the vehicle, death or brain function due to heat stroke may progress, and when the infant is about to get out of the car seat, the neck may be wound around the fixing strap and asphyxia may occur. There are also cases of obstructive phobia as well as heat pain. In addition, if the infant is left in the vehicle for a long time, it may be impossible to breathe due to the gradual increase of carbon dioxide concentration.

Many techniques have been proposed to deal with dangerous accidents in parked vehicles. For example, technologies such as measuring the temperature of the room to open the window of the door, operating the air conditioner, or generating an alarm.

On the other hand, in recent years, the development of electric vehicles rather than the vehicle for the internal combustion engine has been developed, the sale is beginning, and in consideration of environmental issues, the spread of electric vehicles is in a hurry. However, to date, the operating capacity of electric vehicles driven by storage batteries is lower than that of an internal combustion engine vehicle, and there is a shortage of electric charging stations compared to gas stations.

Therefore, the techniques for accidents in the vehicle mentioned above also need to minimize the energy consumption of the electric vehicle.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Preferred embodiments according to the present invention will be described with reference to the accompanying drawings, for the sake of brevity of description, descriptions of overlapping or substantially identical configurations are omitted or compressed as much as possible.

<Description of Configuration of Vehicle Control Device>

1 is a block diagram of a vehicle control apparatus 100 according to an embodiment of the present invention.

The vehicle control apparatus 100 according to the present invention includes a first sensor unit 110, a second sensor unit 120, and a controller 130.

The first sensor unit 110 is provided to detect the existence of a living object inside the vehicle. For this purpose, the first sensor unit 110 may include a weight sensor 111 and a motion detection sensor 112.

The weight sensor 111 is provided to detect the weight of an object placed on a seat inside the vehicle, and may be provided for each seat of the vehicle.

Motion detection sensor 112 is provided to detect the movement of the object inside the vehicle to determine the vitality of the object. The motion detection sensor 112 may be provided as a piezoelectric sensor or an impact detection sensor. In addition, the motion detection sensor 112 may be provided as a camera that can capture the image to detect the movement of the object through the change of the image over time.

The second sensor unit 120 detects a state inside the vehicle when it is detected that a living object exists inside the vehicle through the first sensor unit 110. To this end, the second sensor unit 120 includes a concentration sensor 121 and a temperature sensor 122.

The concentration sensor 121 detects the oxygen concentration in the vehicle. Of course, depending on the implementation, the concentration sensor 121 may be provided to detect the concentration of carbon dioxide in the vehicle.

The temperature sensor 122 detects a temperature inside the vehicle.

The controller 130 operates the second sensor unit by operating at least one of the operation means DM provided in the vehicle in the parking state through the information from the first sensor unit 110 and the second sensor unit 120. Control or raise an alert so that the information value coming from 120 is within an acceptable range. That is, when the presence of the object is detected through the weight sensor 111, the controller 130 determines the vitality of the object through the motion sensor 112, and then the concentration sensor 121 and the temperature sensor 122. The vehicle operating means DMs or generates a warning when any of the information from the information has a deviation value that is outside the acceptable range. For example, when the oxygen concentration in the air inside the vehicle becomes less than 18.5%, which is a value just before the oxygen deficiency concentration reaches 18%, or when the temperature inside the vehicle parked is 10 degrees to 39 degrees, the controller 130 ) Determines that the information is out of the allowable range, and operates the operation means DM of the vehicle or generates an alarm.

Meanwhile, the operation means DM described above may be a lamp, a speaker, a window switch, an air conditioner, a heater, or the like existing inside or outside the vehicle.

The lamp may be a fog light outside the car, a turn signal, a headlight or a light in the car, and the controller may operate one or more of them. Of course, it may be preferable to operate the lamp outside the car rather than the lamp in the car as it may attract the attention of outsiders around the car, and consider other flashing methods with better alertness or visibility than the flashing method of the existing vehicle. Can be.

The speaker generates the alarm as an audible sound. At this time, the sound of the speaker may be implemented such that the sound out of the car rather than in the car, such as a horn.

The window switch is operated to lower or raise the temperature in order to prevent the necessity of indoor ventilation due to lack of oxygen, to prevent burns due to high temperature, to prevent fire or asphyxiation, and to hypothermia due to low temperature.

The air conditioner is operated to reduce the temperature in the room during the summer.

The heater is operated to increase the temperature of the room in winter.

For reference, it is preferable that the above-described operating means DM be operated even when the vehicle is turned off.

Subsequently, a control method by the vehicle control apparatus 100 having the above configuration will be described.

<Control method made in the vehicle control device>

2 is a flowchart illustrating a control method performed in the vehicle control apparatus 100 according to the present invention.

According to the present exemplary embodiment, the controller 130 determines whether the parking state has been started by determining that the time is set at the time when the vehicle is switched to the parked state (for example, turning off all of the vehicle's startup or determining that the occupants are all lowered). Minutes) to determine the presence of a living object inside the parked vehicle through the information detected by the first sensor unit 110, and to control the first mode to the third mode according to the result of the determination.

First, the controller 130 recognizes that the parking state has started <S100>. For example, the controller 130 may recognize that the parking state is started through the opening and closing information of the door in a state in which the start of the vehicle is turned off or the start of the vehicle is not turned off but the gear device is placed in the parking. At this time, when the start of the vehicle is turned off, it may be desirable to wait for a certain time (for example, 10 seconds) required for the getting off of the occupants and to recognize that the parking state has started when the predetermined time is reached.

If it is recognized that the parking state has been started, there is a vitality inside the vehicle parked through the weight sensor 111 and the motion sensor 112 in the first sensor unit 11 for a set time (for example, 3 minutes). Determine the presence of an object <S200>. The controller 130 controls the components required in the first mode, the second mode, or the third mode through the grasp in the step S200. In the following description, the respective modes are divided.

1. First Mode

When the weight of an object is detected by the weight sensor 111 in the seat and the motion of the object is detected by the motion sensor 112, the controller 130 controls the first mode.

In the first mode, the controller 130 is determined to be necessary while periodically operating the second sensor unit 120 according to a set first period (for example, 10 seconds) while continuously monitoring the state of the vehicle interior. It is an active mode for operating <S212> the operation means DM for which operation is required at the time.

That is, in the first mode, when at least one of the information detected by the concentration sensor 121 or the information detected by the temperature sensor 122 has a deviation value that deviates from the allowable range, the controller 130 may open a window. Operate the switch to open or close the window of the vehicle door by the set value, or turn on the ignition and run the air conditioner or heater. And the operation of these operating means (DM) is appropriately controlled to the extent necessary through the information periodically coming through the second sensor unit 120.

For reference, when the first mode is started, it is preferable to turn off the weight sensor 111 to reduce power consumption.

1. Second Mode

If the weight of an object (for example, a heavy bag placed on a vehicle seat) is detected by the weight sensor 111, but the motion of the object is not detected by the motion sensor 112, the controller 130. ) First determines that the object is not a creature and controls the second mode.

In the second mode, the controller 130 turns off the temperature sensor 122, turns on the concentration sensor 121, and periodically adjusts the concentration according to the second cycle (for example, 1 minute). By operating the detection sensor 121 is a standby mode for periodically detecting only the concentration of oxygen or carbon dioxide <S221>.

In this second mode, after detecting whether there is a change in the gas concentration using the information detected in step S221, the controller switches to the first mode if there is a change in the gas concentration, and returns the second mode if there is no change. Keep it.

Wherein the second period is longer than the first period. This is because if it is not determined as the first mode, there is no living object in the vehicle. Nevertheless, in order to take into account the existence of life that may be present in the bay, to monitor the change in gas concentration, it is to minimize the waste of power by performing a long period of sensing rather than a short period of sensing. This is because it is necessary to consider the fact that it is necessary to keep the parking state for a long time without using the vehicle after returning home.

On the other hand, even when the second mode is selected, the motion detection sensor 112 needs to be implemented to switch to the first mode when motion of the object is detected by periodically operating. Similarly, the detection period of the motion detection sensor 112 in the second mode is preferably longer than the detection period of the motion detection sensor 112 in the first mode.

In addition, the controller 130 controls in advance to open the window of the vehicle door by the set value at the start of the second mode when the external temperature value from the external temperature sensor is equal to or greater than the set value (for example, 30 degrees). It is desirable to. In other words, it is necessary to consider that the object present in the second mode, although it is determined as the second mode, may have vitality, and also it is necessary to make sure that the temperature of the room is not too high at the time when the driver or the like later boards. to be.

Similarly, in the second mode, when the presence of the object is detected by the weight sensor 111, it may be considered to turn off the weight sensor 111.

1. The third mode

The third mode is selected when the weight sensor 111 determines that there is no other object inside the vehicle. For example, if the information coming through the weight sensor 111 is equal to the previously set value (the value when there is no object in the vehicle seat) it can be determined that there is no other object inside the vehicle, the controller 130 By controlling in the third mode, both the first sensor unit 110 and the second sensor unit 120 are turned off to eliminate waste of power.

<References>

Parking in the above embodiment means that the vehicle has been stopped for a long time similarly to the parked state as well as the parked state with the vehicle completely turned off. For example, it may include a case where the vehicle is stopped for 5 minutes or more or for a time set in the controller. That is, it covers the case where the car stays in a certain place regardless of whether the ignition is on or off. In addition, for example, the five minutes mentioned above are arbitrarily illustrated to explain the present invention, and may sometimes go to a mart or other business for a considerable time while the ignition is turned on. In consideration of this, the setting can be made in units of 5 minutes or less. In most cases, it can be considered that there is no problem if the air conditioner is turned on in the summer and the heater is turned on in the winter regardless of whether the vehicle is started, but this can be a very dangerous idea. The present invention with the invention is a very important invention. Not only the discharge of the battery but also a fire due to overheating, and if the parking and stopping place is a closed place may be a choking by smoke. This situation should be monitored to enable real-time response using reserve power regardless of whether the vehicle is started or not. Therefore, the meaning of parking described in the embodiments or claims of the present specification should be interpreted to mean not only normal parking but also a stop over a set time.

<Additional matter>

In addition to the above embodiment, as further referred to in FIG. 1, the communication unit 140 may be mounted on the vehicle, and the communication unit 140 and the mobile terminals M1 and M2 of the user (driver or other designated person) may be mounted. It may be implemented to communicate. The communication here may be a short range communication such as Bluetooth, but depending on the implementation may be a communication using a Wi-Fi or a mobile communication network.

 In this case, the controller 140 may periodically send information to the mobile terminals M1 and M2 of the driver or the designated person through the communication module 140.

At this time, the information sent to the driver's or designated person's mobile terminals M1 and M2 is estimated how long has passed since leaving the vehicle, the gas concentration or temperature in the vehicle is expected to exceed the allowable range, and Information such as whether actions were taken.

In addition, the position of the communication unit 140 and the mobile terminals M1 and M2 can be tracked, and the information is sent to the drivers or mobile terminals M1 and M2 of the designated person through the communication unit 140. Information about how far is the vehicle from the vehicle and whether it is possible to reach the vehicle within a certain time on the current distance.

In addition, it may be considered to implement to send the image taken through the camera to the mobile terminal (M1, M2) of the driver or designee, the camera at this time may be provided separately or may utilize the existing camera for the black box.

In addition, the present invention is to prepare for the extreme situation such as suicide through the setting of the controller 140. In other words, when detecting the temperature and gas concentration in the vehicle, it is possible to immediately set the notification to transmit the ventilation and alarm situation to a designated person other than the driver can be extended to prevent the driver's own accident in advance.

In some cases, the information may be transferred to the drivers and the mobile terminals M1 and M2 of the driver and the designated person to be able to take action. That is, the vehicle itself must determine the emergency situation and notify the driver or designee.

When such a communication is possible, a process of providing a notification through the communication unit 140 may be added in the flowchart of FIG. 2.

Further, the driver or designator may further transmit a command for controlling the vehicle from the mobile terminals M1 and M2 to the control unit 140, and the control unit 140 having received the command may change the vehicle according to the command. There is also a need to implement to control the operation means to operate. In this case, the control according to the self-determination of the control unit 140 mentioned in the above embodiment may be omitted, but it is more preferable that the control according to the self-determination of the control unit 140 or the control according to the command is possible. something to do.
