BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a head-up display of a vehicle. In particular, the present invention provides a shortest driving route to a vehicle's destination and an estimated time of arrival when the vehicle is driven, and informs a situation about a traffic accident on the driving route to arrive at the destination quickly. The present invention relates to a vehicle driving information notification device and method using a head-up display.

Nowadays, more and more people are driving their own cars to get to their destinations due to the increasing number of vehicles, and because of the complicated road conditions and the increasing number of vehicles, many vehicles coming from behind do not move quickly and accurately to their destinations. It hindered progress.

If the driver is embarrassed because the driver does not know the route to the destination in the case of a first-time or crowded city, the operation of the vehicle is further delayed and it is difficult to find the destination.

In particular, if you can't quickly decide whether you want to turn left, turn right, or make a U-turn at an intersection, you'll miss the opportunity to change lanes and have to change directions sharply, or you'll just have to go past and use a distant road to get back.

Therefore, the data of each map is subdivided and input using CD-ROM (Compact Disk Read Only Memory) for vehicle navigation system, and then GPS (Global Positioning System) using a satellite, gyro sensor, geomagnetic sensor, vehicle speed sensor, etc. By matching the current vehicle location with the map data, it is easy to search the road or select the route.                         

In this case, when the road information is provided through a separate monitor, the driver needs to watch the monitor in order to observe the provided information, thereby reducing the concentration of driving.

In order to solve this problem, a head up display (HUD) technology for projecting road information onto a front windshield of a vehicle so that a driver may look at the front of the vehicle and obtain road information is disclosed.

In the case of the above technology, although the optimal route from the current position of the vehicle to the target position and the current vehicle information can be displayed, it cannot be notified when a traffic accident occurs on the optimal route, and the vehicle is delayed even when entering the optimal route. There was a problem.

In addition, there is a problem that the arrival time to the vehicle destination is unknown.

The present invention has been made to solve the above problems, by using the head-up display device of the vehicle tells the driving time when using the optimal route and the optimal route to the destination when driving the vehicle and when the accident occurs on the optimal route to the driver An object of the present invention is to provide an apparatus and method for notifying vehicle driving information using a head-up display.

1 is a block diagram showing a configuration of a vehicle driving information notification device using a head-up display according to the present invention. In the head-up display device of a vehicle, a GPS receiver for receiving coordinate data and visual data transmitted from a GPS satellite ( 10), the vehicle speed sensor 20 for measuring a driving speed of the vehicle and outputting a corresponding signal, a gyro sensor 30 for detecting whether the vehicle is being driven and outputting a corresponding signal, the GPS receiver 10, Inputs the mapping signal output from the telematics module 40 and the telematics module 40 to map the current vehicle position and output the corresponding signal using the signals output from the vehicle speed sensor 20 and the gyro sensor 30. The controller 50 outputs the driving information and the control signal for the driving state of the vehicle, and the driving information of the vehicle is controlled by the control signal output from the controller 50. Display shows that it is composed of a display device 100.

The display device 100 is a head-up display 110 for displaying a direction signal according to the driving information output from the control unit 50, a display for displaying the position of the vehicle and the surrounding road conditions output from the control unit 50 The panel 120 and the speaker 130 may output a driving direction indication sound by voice based on driving information and a control signal output from the controller 50.

2 is a flowchart illustrating a configuration of a vehicle driving information notification method using a head-up display according to the present invention, and illustrates operations of the GPS receiver 10, the vehicle speed sensor 20, the gyro sensor 30, and the telematics module 40. Turning on (ST100), turning on the operation of the head-up display 110 and the display panel 120 of the vehicle (ST200), vehicle information such as driving speed, engine speed and fuel amount of the vehicle Displaying using the display (ST300), searching for the shortest route to the destination to display and select the display panel 120 (ST400), the driving direction while driving the display and the selected path in the step (ST400) It is preferable that the step of displaying through the head-up display (ST500), and the guidance broadcast when the path deviates (ST600).

The displaying of the shortest route (ST400) may include displaying first, second and third routes to a destination (ST410), selecting a first route (ST420), and selecting a second route ( ST430), and selecting the third path (ST440).

The displaying of the driving route (ST500) may include displaying an estimated driving time (ST510), displaying the shortest driving route selected by the controller 50 on the head-up display (ST520), and driving a traffic accident on the driving route. It is preferable that the operation (ST 530) is notified to the driver (ST 540), and a step (ST 550) for displaying a new route at the current position.

When explaining the embodiment of the present invention configured as described above with reference to the drawings as follows.

When the engine is started to drive the vehicle, a generator (not shown) is operated by the operation of the engine, and at the same time, the GPS receiver 10, the vehicle speed sensor 20, the gyro sensor 30, and the telematics module 40 are operated. The head-up display 110 and the display panel 120 of the vehicle are sequentially turned on (ST100, ST200).

Various sensors installed in the vehicle measure the operation state of each component of the vehicle and output a signal indicating the measured state, and the output signal is input to the telematics module 40 to calculate mapping information of the vehicle. The information is converted into necessary information and then input to the controller 50.

The controller 50 converts and outputs the input information so that the driver can know, and the output information is input to the display device 100 and displayed to the driver (ST300).

That is, when the driver is notified of the state such as the driving speed, the engine speed, the fuel amount, and the coolant temperature of the vehicle through the head-up display 110, the driver may obtain vehicle information without leaving the vehicle front gaze state.

In addition, at the same time as the engine operates, the GPS receiver 10 receives geographic information around the vehicle and displays the received information on the display panel 120.

The driver inputs his / her destination (ST410), and when the destination is input, the controller 50 displays a path connecting the current vehicle location and the input destination (ST400). Since there are several paths from the location where the vehicle is located to the destination, all of the first, second, and third paths connecting the current location and the destination are displayed (ST420).

The controller 50 notifies the driver that there are several routes, searches for the shortest route in consideration of a situation such as a driving distance and a traffic situation, and selects one of the displayed routes (ST430, ST440, ST450). It is desirable to inform the driver.

In this case, when there are a plurality of routes having similar distances to the destination, it is desirable to display all of them so that the driver can select them.                     

When driving of the vehicle starts, the estimated driving time when the vehicle travels the route selected by the controller 50 using the average road speed is calculated and notified to the driver (ST510). In this case, the average road speed used to calculate the estimated driving time is an average speed of traffic flow observed in a certain road section, and is a value calculated by dividing the sum of the driving distances of the vehicles traveling in the certain road section by the sum of the driving time. It is desirable to calculate using traffic information received using a receiver.

When driving of the vehicle starts, the driving route selected by the controller 50 is displayed on the head-up display 110 to instruct the driver to know the driving route (ST520). That is, when the vehicle needs to travel in a straight line, a straight driving mark is displayed. When the vehicle turns left or right at an intersection, a left turn instruction or a right turn instruction is displayed on the head-up display before arriving at the intersection (eg, 50m).

If a traffic accident occurs on the selected driving route while driving toward the destination by using the information displayed by the head-up display 110, a traffic jam occurs due to the traffic jam, so that information related to the traffic accident is obtained (ST530). The controller 50 may notify the driver of the driver through the head-up display 110 (ST540) and inform the new shortest path in the situation (ST550). In the event of a traffic accident, the driver should drive on a new route.

When the vehicle deviates from the driving path due to the driver's carelessness while driving through the selected driving path, the controller 50 detects the deviation of the path and outputs a control signal by using the signal output from the gyro sensor 30. Output the exit signal through (ST600).

As described above, according to the present invention, after selecting the driving route of the vehicle, the head-up display of the vehicle informs the driving route and the estimated time, and if a traffic accident occurs on the driving route, the driver is notified and the new route is informed. It has the effect of being able to arrive at the destination quickly.
