Description

Technical Field [0001] The present invention relates to an automotive quick braking indication device,

More particularly, the present invention relates to a vehicular emergency braking display apparatus and, more particularly, to a vehicular emergency braking display apparatus, To a vehicle speed controller.

On the road where the vehicle is running at high speed like a highway, the driver turns on the emergency light provided in the vehicle in case of an emergency in front of the driver, for example, in case of a sudden decline due to entry of the congestion section, Since the vehicle in the rear has an emergency ahead, it sends a signal to operate the vehicle carefully. However, in the case where a vehicle collision can not be turned on due to insufficient driving, or a collision accident occurs in the state where the emergency light is not turned on, the possibility of a rear-end collision or a secondary collision accident is greatly increased. Many suggestions have been made to reduce these accidents.

Japanese Patent Application Laid-Open No. 10-2005-0068949 discloses a system and method for preventing collision using telematics and Bluetooth. The present invention relates to a vehicle collision avoidance system, a collision avoidance system, and a collision avoidance system. In the collision avoidance system, The vehicle traveling in the same direction as that of the vehicle causing the collision among other vehicles suddenly bounces when it receives such a notice within the effective distance of the Bluetooth communication and carries the vehicle running in the opposite direction to the vehicle that caused the collision among the other vehicles When it receives such a notification within the effective range of the Bluetooth communication, it turns on the emergency warning light and proceeds slowly.

Japanese Patent Application Laid-Open No. 10-2008-0014372 (published on Feb. 14, 2008) discloses a communication system and method for a safety tripod and a vehicle BCM. This invention adds a function of mutual communication with rear vehicles to a safety tripod displayed on the road in order to draw attention to the rear vehicles in the event of a malfunction or an accident of the vehicle. The rear-end vehicles that receive signals from the safety tripod blink the vehicle's emergency lights and draw attention to the vehicles behind them.

In addition, proposals have been made to prevent the occurrence of a secondary collision accident by allowing the police to notify the police of the occurrence of an emergency in the event of a vehicle accident, Japanese Patent Application Laid-Open No. 2000-0019921 (published Apr. 15, 2000), Japanese Patent Application Laid-Open No. 10-2007-0031640 (published on Mar. 20, 2007), Japanese Patent Application Laid-open No. 10-2007-0060570 (Jun. Patent Registration No. 10-0835385 (Registered on May 29, 2008), Patent Publication No. 10-2010-0005361 (Published on Jan. 15, 2010), Patent Publication No. 10-2011-0113379 (2011 (Published on Dec. 17, 2012), Patent Publication No. 10-2012-0060511 (published on June 12, 2012), Patent Publication No. 10-2012-0095540 (published on Aug. 29, 2012) 1998-050273 (published on October 10, 1998).

In the above prior arts, the collision avoidance system is installed so as to be interlocked with the devices that operate the vehicle, for example, the ECU, the accelerator, and the brake device. If such a collision avoidance system malfunctions, it may prevent the collision, thereby contradicting the object of improving the safety of the vehicle, that is, causing a serious deterioration of the safety of the vehicle. Therefore, in order to secure the safety of the vehicle, such a collision avoidance system has a disadvantage that it must pay a higher cost than the additional performance, since the vehicle must be tested after the vehicle is tested with sufficient safety. In addition, if the collision avoidance system receives power from the battery of the vehicle at the time of a collision or a collision of the vehicle, the collision avoidance system can operate normally. However, if the power supply is interrupted due to an accidental impact, the collision avoidance system can not operate normally. The system may become obsolete.

SUMMARY OF THE INVENTION The present invention has been made in order to solve the problems of the prior art. Accordingly, it is an object of the present invention to provide a vehicle emergency braking system for a vehicle, which is mounted on a vehicle to operate independently of the devices that operate the vehicle, that is, the ECU, the accelerator and the braking device, The present invention is to provide a vehicle emergency braking display device that operates normally even when an accident occurs in a vehicle without worrying about the safety of the vehicle by constituting the display device.

2 is a part of a flowchart showing an operation example of the vehicle rapid braking display device of the present invention.
3 is a part of a flowchart showing an example of operation of the vehicular rapid braking display device of the present invention, which follows the flowchart of Fig.

Hereinafter, the present invention will be described in detail with reference to the drawings.

BRIEF DESCRIPTION OF THE DRAWINGS FIG. 1 is a schematic view of a vehicle rapid braking display device according to an embodiment of the present invention; FIG. 1, a vehicle speed control display device 10 according to the present invention includes a sensor unit 100, a control unit 200, a display unit 300, a battery unit 400, a charging terminal 500, (600) and may also include an input unit (900).

The sensor unit 100 detects any one of the position, velocity, and acceleration of the vehicle. The sensor unit 100 is most preferably composed of a GPS receiver, and may be constituted by a speed sensor or an acceleration sensor. The sensor unit 100 may further include a crash sensor that operates separately from the GPS receiver, as described below. In this case, as described below, if an impact amount exceeding the reference value is detected by the collision sensor, it can be considered that the vehicle caused the collision.

The control unit 200 receives the position, velocity, or acceleration data from the sensor unit 100 and calculates the acceleration of the vehicle. When the vehicle is decelerating and the acceleration magnitude of the vehicle is larger than the reference acceleration magnitude, the control unit 200 generates an LED lamp flashing command and sends it to the display unit 300.

The display unit 300 is composed of LED lamps blinking in response to the LED lamp flashing command of the control unit 300. The LED lamp used in the display portion is preferably a high-latitude LED.

The battery unit 400 supplies power to the sensor unit 100, the control unit 200, and the display unit 300. The battery unit 400 is provided separately from the battery of the vehicle and operates independently of the battery of the vehicle. The battery unit 400 may be configured as a primary battery, such as a dry battery, but is preferably configured as a secondary battery.

When the battery unit 400 is configured as a secondary battery, a charging terminal 500 is formed. The battery unit 400 may be charged by the battery of the vehicle, but is preferably charged by the solar cell 600. Since the battery unit 400 is charged by the solar cell 600, the vehicle rapid-motion-indicating device 10 of the present invention can be mounted on the outer wall of the ceiling or other part of the vehicle with a magnet or double- It is possible to always operate by generating electricity by the solar cell 600 in the daytime and charging the battery unit 400 without a driver's operation. The vehicular rapid braking display device 10 of the present invention is designed in the shape of a shark antenna and attached to a ceiling or other outer wall so that it does not significantly affect the traveling of the vehicle and can provide decorative beauty to the vehicle.

Meanwhile, the vehicle bust control display device 10 of the present invention may further include an input unit 900. The input unit 900 may be a power switch or an initialization switch that first turns off the power. The input unit 900 is not necessarily required. As will be described below, the vehicular rapid dispenser display 10 of the present invention is completely free from operation even when the input unit 900 is not provided. However, if there is no input unit 900, if the control unit 200 malfunctions and the power supply to the battery unit 400 is not cut off even after a predetermined period of time while the speed of the vehicle is 0, the power of the battery unit 400 is completely discharged, And the battery unit 400 can not supply power, the vehicle rapid dispenser display 10 of the present invention can prevent the solar cell 600 from being electrically powered And is incapable of operating until the battery unit 400 is charged. If there is a malfunction of the control unit, this inconvenience may be followed. However, the inconvenience is not fatal, and it is not necessary to place the input unit because it is more convenient that the user does not care about the power supply. Whether or not the input unit is installed, the driver is convenient because it is not necessary to perform any operation such as turning on / off the vehicle acceleration display device 10 of the present invention at all.

In addition, it is not excluded to place an input button or a switch for other functions as the input unit 900. However, it is useful in terms of simplification of structure and reduction of cost to place only a power switch or an initialization switch.

The vehicle bust control display device 10 of the present invention having such a configuration is mounted in the vehicle independently of the devices that operate the vehicle, that is, the ECU, the acceleration device, and the braking device. Also, the battery unit 400 is separately provided for the battery of the vehicle and operates independently, and the display unit 300 is separately provided for the emergency light of the vehicle and operates independently.

According to such a configuration, in order to always operate the vehicle rapid dispenser display apparatus 10 of the present invention when the vehicle is running without the user intervention, the battery unit 400 must always supply power to the control unit 200, ) Must always be in an operational state. This is because the control unit 200 must be able to determine whether the vehicle is being driven or parked. Further, the controller 200 may be operated by an additional sensor for providing information for determining whether the vehicle is being driven or parked, or the GPS receiver must be operated. If the power supply to the operation of the additional sensor or the operation of the GPS receiver is continued, the vehicle speed controller 10 of the present invention can not operate substantially with a small capacity battery. Therefore, as a further configuration for efficient power management, the vehicle rapid braking display device 10 of the present invention further includes a power control unit 700 and a mini wind power generator or a piezoelectric element 800. [

The power control unit 700 is connected between the battery unit 400 and a component to be supplied with power such as the sensor unit 100, the control unit 200 and the display unit 300, and is also connected to the mini wind power generator or the piezoelectric element 800, Lt; / RTI > The mini wind power generator 800 is mounted on the outer wall of the vehicle as a small size wind power generator. When the vehicle travels, the mini wind power generator 800 produces electricity as the wing of the mini wind power generator 800 turns. A current is supplied to the power supply control unit 700 by the electricity generated by the mini wind power generator 800 and the power supply control unit 700 conducts electricity between the component to be supplied with power and the battery unit 400 So that the power of the battery unit 400 is supplied to the sensor unit 100, the control unit 200, and the display unit 300. In the vehicle rapid braking display device of the present invention, a piezoelectric element can be used instead of a mini wind power generator. The piezoelectric element generates electricity when pressure or vibration is applied. In the state where the vehicle is stopped, there is no electricity generated because no pressure or vibration is input to the piezoelectric element. However, when the vehicle starts to travel, Such vibration of the vehicle is input to the piezoelectric element to produce electricity. The electricity thus produced, that is, the electric current, is supplied to the power control unit 700. Therefore, the piezoelectric element has the same function as the mini wind power generator in the vehicle rapid braking display device of the present invention.

The power control unit 700 includes a thyristor 710 and a relay 720. The relay 720 is connected to the battery unit 400 and also to the thyristor 710 and is also connected to the control unit 200. The relay 720 is in the contact B without being controlled by the controller 200, and in this state, the battery unit 400 and the thyristor 710 are connected. On the other hand, as will be described later, in the case of being controlled by the control unit 200, the battery unit 400 is moved to the contact point A so that the battery unit 400 is disconnected from the thyristor 710, .

The thyristor 710 is connected to the relay 720 at the anode terminal and is connected to the mini wind power generator or the piezoelectric element 800 at the gate terminal and is connected to the sensor unit 100, the control unit 200, and the display unit 300 at the cathode terminal, Lt; / RTI >

Fig. 2 and Fig. 3 are flowcharts showing an example of operation of the vehicle rapid braking display device of the present invention. Now, with reference to Figs. 2 and 3, the operation of the vehicle rapid braking display apparatus of the present invention will be described.

First, in the vehicle rapid braking display device 10 of the present invention, power supply is not performed in the initial state, and power supply is not performed even by switch operation of the user. When the vehicle rapid braking display device 10 of the present invention is driven on the outer wall of the vehicle, for example, on the ceiling of the vehicle, the mini wind power generator or the piezoelectric element 800 starts to produce electricity. Current is supplied to the gate terminal of the thyristor 710 by the mini wind power generator or the piezoelectric element 800. When the magnitude of the current exceeds the threshold value, the anode terminal and the cathode terminal of the thyristor 710 are made conductive do. Thus, the power source of the battery unit 400 is supplied to the sensor unit 100, the control unit 200, and the display unit 300, respectively (step S100). After the thyristor 710 is turned on, the thyristor 710 is kept in a continuously conductive state even if no current is supplied to its gate terminal.

Next, the position of the vehicle is continuously received from the GPS receiver with respect to time (step S110), and the speed and acceleration of the vehicle are calculated from the position of the received vehicle (step S120). The speed of the vehicle can be obtained by differentiating the position of the continuously received vehicle with respect to time, and the acceleration of the vehicle can be obtained by differentiating the speed of the vehicle with respect to time.

The control unit determines whether the vehicle speed is greater than zero (step S130). At this time, if the vehicle speed is not greater than 0, that is, if the vehicle speed is zero, it is determined whether the elapsed time is equal to or greater than the reference value (step S140). If the time exceeds the reference value in the state where the vehicle speed is zero, the control unit finishes the running of the vehicle and regards the vehicle as parked, thereby completing the operation of the vehicle rapid braking display apparatus of the present invention. That is, the supply of power to the vehicle speed controller is stopped. To this end, the control unit controls the relay so that the relay moves from the contact B to the contact A (step S150). When the contact of the relay is adjusted from B to A, the relay disconnects the connection between the battery unit 400 and the thyristor 710, and eventually the power supply to the battery unit 400 is stopped. Since the power supply from the battery unit 400 is cut off, the control unit no longer operates, so that the contact of the relay can not be maintained at A continuously, and the relay becomes the contact B state. The reference value for the elapsed time in the state where the vehicle speed is zero can be set to a time such that the vehicle can be recognized as a parking state, for example, 10 minutes. Normally, if the vehicle is not moving for about 10 minutes, there may be a case where the vehicle is stopped for a long time. It is rather reasonable to terminate the operation of the vehicle rapid braking display device of the present invention even when the vehicle is stopped for a long period of time.

On the other hand, if the time duration in which the speed of the vehicle is zero is less than the reference value, the procedure returns to step S130 and continues.

Next, the control unit judges whether the acceleration of the vehicle thus obtained is less than or equal to the reference acceleration (step S160). At this time, the reference acceleration has a negative value. Therefore, the control unit is to determine whether the vehicle is decelerating and the acceleration magnitude of the vehicle is greater than or equal to the reference acceleration magnitude. In other words, the control unit judges the degree of deceleration of the vehicle.

If the degree of deceleration of the vehicle is not equal to or greater than the reference value, it means that the emergency situation has not occurred in the front of the vehicle, so the procedure returns to step S110 and continues. However, if the degree of deceleration of the vehicle is equal to or greater than the reference value, it means that an emergency has occurred in front of the vehicle, so that the control unit generates an LED lamp flashing command of the display unit 300 and transmits it to the display unit (step S170). Then, the display unit 300 blinks the LED lamp. In order to blink the LED lamp of the display unit 300, the control unit may set the flashing speed and the brightness of the display unit 300 to increase as the size of the deceleration of the vehicle is increased. For example, the first reference value, the second reference value, the third reference value and the like are set according to the deceleration magnitude of the vehicle, and when it is equal to or greater than the first reference value, the LED lamp starts blinking, And the second flash rate and the second flash rate are increased. When the second reference value is reached, the flashing speed and the brightness are increased. 3 and the third light intensity.

In this situation, the control unit continuously receives the position of the vehicle from the GPS receiver continuously in time (step S180) to determine whether the emergency situation continues in the front of the vehicle again or if the emergency situation is released (step S180) The vehicle speed and the acceleration are calculated (step S190). Then, the control unit determines whether the vehicle speed is greater than zero (step S200).

If the speed of the vehicle is not greater than 0, that is, if the speed of the vehicle is 0, the emergency situation should be maintained since the vehicle may be stopped by a collision or collision with the preceding vehicle or a roadside facility It is determined that the LED lamp of the display unit 300 is continuously blinking.

In order to more clearly determine whether or not an accident occurred in which the vehicle collided with the front vehicle or the facility, the vehicle acceleration display device of the present invention may further include a crash sensor have. The collision sensor detects the amount of impact received by the vehicle and transmits it to the control unit 200. The control unit compares the collision signal received from the collision sensor with a reference value. If the value of such a collision signal is greater than or equal to a reference value, the control unit regards that the vehicle has caused a collision and determines that the collision has occurred at a maximum flashing speed and a maximum brightness, for example, 4 and the fourth light intensity display unit.

If the vehicle speed is zero, the control unit measures the elapsed time of such a state and compares the elapsed time with the reference value (step S210). If the elapsed time does not meet the reference value, the procedure returns to step S200 to determine whether the speed continues to be zero. When the elapsed time has reached the reference value, as described above, the control unit controls the relay to move the relay from the contact B to the contact A in order to terminate the operation of the vehicle rapid braking display apparatus of the present invention (step S220). In this case, however, the reference value for the elapsed time should be appropriately set to the time required for the accident handling after occurrence of the collision accident, and therefore, it is desirable to set the reference value longer than the above case. For example from 30 minutes to 1 hour.

On the other hand, when the vehicle speed is greater than zero, that is, when the vehicle is moving, it is determined whether or not the vehicle is decelerating or accelerating (step S230).

If the acceleration of the vehicle is less than 0, that is, if the vehicle is continuously decelerating, it means that the emergency is continuing in front of the vehicle. Therefore, it is determined that the emergency should be maintained and the LED lamp of the display unit 300 As the state continues to blink, the procedure returns to step S180 to continuously receive the position of the vehicle from the GPS receiver. On the other hand, when the acceleration of the vehicle is 0 or more, it is determined that the emergency in the front is released and the LED lamp of the display unit 300 is turned off (step S240).

In FIG. 4, the determination as to whether or not the acceleration of the vehicle is equal to or greater than 0 is made at any one time. However, it is preferable to determine whether the vehicle speed is kept the same or increases in the non-zero state for a predetermined time. Here, the predetermined time may be appropriately selected, but may be, for example, 0.01 second to 0.1 second.

In fact, a seasoned driver is likely to repeat the braking step in order to ensure the safety of the vehicle, even if the driver suddenly brakes suddenly in the face of an emergency. In addition, in the vehicle employing the ABS (Anti-Brake System), even if the driver continuously applies the brakes, the brakes are repeatedly operated and non-operated by the operation of the ABS. According to this operation, the moment the foot is released from the brake while the brake pedal is depressed, the speed may slightly increase momentarily. Therefore, if it is determined in step S230 that the instantaneous acceleration is equal to or greater than 0, an error may occur. Therefore, in step S230, it is preferable to determine the average acceleration for a time interval of, for example, 0.01 second to 0.1 second, rather than determining the instantaneous acceleration as an object.

Next, the control unit judges whether or not a request for power-off is input (step S250). In such a case, the procedure is ended. If there is no request for power-off, the procedure returns to step S110 and continues. The input unit 900 may not be installed, and in such a case, step S250 is not performed.

This procedure is performed in a state in which the vehicle rapid dispensing indicator 10 of the present invention is attached to the ceiling or other outer wall of the vehicle and the vehicle rapid dispensing indicator 10 of the present invention is mounted on the battery pack 10, And is automatically performed by the control unit by issuing an alarm by its own display unit 300 regardless of the emergency light of the vehicle. Therefore, the vehicle speed control display device of the present invention does not have a fatal effect on the vehicle even if a malfunction occurs, so that it can be used without a strict test on the safety of the vehicle, so that the ratio of cost to performance is high, Even if the power supply system by the battery is damaged, it can be operated normally, so that the emergency warning function of the vehicle can be reliably performed. Also, the safety of the vehicle can be taken even if the driver is inexperienced. .

Further, the vehicle rapid dispenser display device of the present invention can supply power only when the vehicle is running, and when the vehicle is being parked, the power supply is cut off, so that the battery power management can be efficiently achieved and the battery can be stably used even with a small capacity battery. In particular, when the battery is continuously charged by the solar battery, the battery can be continuously used without user intervention to charge the battery.
