DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Hereinafter, a simulation system and its simulation method for determining the operation possibility according to the present invention will be described in detail with reference to the drawings.

1 is a vehicle interior view schematically showing a simulation system for judging the operation possibility according to the present invention.

A simulation system for determining the likelihood of motion according to the present invention comprises a vehicle running control device (10); A head-up display (20) arranged on a driver's main sight line for displaying a selected simulation mode among a plurality of predetermined simulation modes and an execution result for the corresponding simulation mode; And a simulator controller 30 for determining whether or not the operation is possible and controlling the corresponding simulation mode displayed on the head-up display 20 in conjunction with the operating device 10. [

The vehicle running manipulation apparatus 10 according to the present invention is an apparatus that is required when the driver actually operates the vehicle and is operated by the user. The manipulation apparatus 10 includes a key insertion port 11 or a button for turning on / off the starting of the vehicle, A tilt sensor 12 for measuring an inclination degree of the vehicle, a hand brake 13, a turn signal light manipulator 14, a steering wheel 15 or a steering wheel, an accelerator pedal 16, a brake pedal 17, A light manipulator, a gear transmission, and the like.

A sensor or a sensing unit that can be detected when the driver operates the vehicle may be provided inside or outside the vehicle, and the signal detected by the sensor or the sensing unit may be applied to the simulator controller 30 .

The head-up display 20 is generally referred to as a head-up display (HUD), and is a device that is disposed in a range not exceeding the driver's front view of the driver or the driver, such as a vehicle or an aircraft, . At the time of driving, the driver confirms the objects in sight and at the same time confirms the driving condition of the vehicle without looking at the instrument panel, thereby preventing accidents caused by dispersion of attention.

The head-up display 20 generally displays a speed during driving, an abnormality in a vehicle, and the like. In the present invention, a plurality of predetermined simulation modes are selected according to the control of a simulator controller 30 to be described later, The results are also displayed. The plurality of preset simulation modes may preferably include a reaction time test mode, a lane change mode, and a scenario execution mode, and each simulation mode is preferably stored in a memory in a simulator controller 30 to be described later. Such a simulation mode can be continuously developed and updated to determine the optimum operation possibility, and a detailed description of each simulation mode will be described later.

The head-up display 20 can be driven using various known methods. When the driving method of the head-up display 20 is determined, the head-up display 20 can be controlled using the driving method determined by the simulator controller 30 to be described later.

The simulator controller 30 judges whether or not the simulation system according to the present invention is operable. It is preferable that the simulator controller 30 judges that starting from the signal of the key insertion port 11 in the operating device 10 or that the signal from the tilt sensor 12 or the hand brake 13 is stuck, It is possible to control the simulation system according to the present invention not to operate. In addition, when the start-up is already performed, the simulator controller 30 can send a signal that the present invention can not be started. This is the first priority on the simulation system according to the present invention for the safety of the driver, and it can indicate that the current vehicle environment in the head-up display 20 described above can not operate the simulation system.

The simulator controller 30 operates in conjunction with the above-described vehicle running control device 10, and can receive signals sensed by a sensor or a sensor installed in the control device 10 in a wired or wireless manner. Of course, a signal may be sent from the simulator controller 30 to the operation device 10. For example, if a light is operated while the simulation system for determining the motion possibility is operating, it may cause inconvenience to a nearby vehicle or a citizen. The light may not actually be operated by the signal received by the light manipulator. Or the simulator controller 30 can send a signal to prevent the instrument panel of the vehicle from operating.

The simulator controller 30 controls the corresponding simulation mode displayed on the head-up display 20 in conjunction with the operating device 10. [ As described above, the head-up display 20 displays a selected simulation mode among a plurality of predetermined simulation modes. When the respective operating device 10 is operated by the driver, the simulator controller 30 displays the change Can be processed and analyzed so that they can be reflected instantaneously or with a certain time delay. In addition, the simulator controller 30 may control the head-up display 20 to display a sign for safety when the selected simulation mode ends. The sign is indicative of the current position of the operating device 10 and is returned to the initial position. The initial position may be indicated by a dotted line, and may be displayed accompanied by an explanation with an arrow or a letter.

Hereinafter, a plurality of preset simulation modes will be described in detail with reference to Figs. 2, 3 and 4. Fig. The method of selecting one of the plurality of predetermined simulation modes is not limited, and the display portion embedded in the front interi of the vehicle may be directly selected by using a button disposed near the touch or display portion, .

Reaction time test mode

2 is a diagram illustrating an embodiment of a reaction time test mode in a simulation system for determining the operation possibility according to the present invention.

In the reaction time test mode, the above-described head-up display 20 displays one or more marks associated with the running of the vehicle, and the simulator controller 30 can analyze the time the driver reacted to the marked mark.

At this time, the marks related to the vehicle driving may be a traffic light, a sudden stop, a lane change, a U-turn, an emergency light, a turn signal operation, a weather, a road surface condition, a road congestion, May be displayed.

As shown in FIG. 2, the mark 21 related to the sudden stop can be instantaneously displayed on the head-up display 20, and at this time, how fast the driver reacts and whether or not the emergency flashing button is pressed is performed in the response time test mode Can be reflected in the results. Or how fast the driver has reacted when the mark 22 related to the lane change is displayed on the head-up display 20, etc., may be reflected in the result of the operation, and the operation mode of the lane change mode described later may be applied .

The other marks indicate that the driver will be able to see the results of the operation in a positive manner. In addition, in the case of the weather, when a rain or snow related mark is displayed, the wiper is operated, the speed is reduced, and the speed of the vehicle is changed. The mark related to the movement of the opponent vehicle may include a mark where the opponent vehicle is suddenly stopped, a mark by which the opponent vehicle changes lanes, an engaging mark, and the like.

In addition, in the reaction time test mode, the head-up display 20 can display the time when the average driver reacted to the driver actually riding on the marked mark. It is preferable that the average time of the driver's response is previously set in the memory of the simulator controller 30 while being divided by age and each mark.

The reaction time comparison table 23 in the reaction time test mode can be displayed together with the result of the reaction after the end of the reaction time test mode in the head-up display 20, and can be displayed after the evaluation for each mark is completed have. The reaction time comparison table (23) is not limited to a bar graph, and can be applied if the response time of the actual boarding driver and the average driver are clearly distinguishable. In addition, performance results can be numerically expressed and displayed as a score. If the result is below a certain score, it can be indicated that the current operation is dangerous.

By using the simulation system for determining the operation possibility according to the present invention, it is possible to determine how much the difference in the reaction time of the actual driver is compared with the response time of the average driver, It is possible to judge the possibility of operation.

Change lane mode

3 is a diagram illustrating an embodiment of a lane-changing mode in a simulation system for determining operationality according to the present invention.

In the lane change mode, the head-up display 20 described above can display the driver's vehicle position 25, the relative vehicle position 26 and the lane 27 as shown in Fig. At this time, the lane 27 is displayed in a moving form so that the driver's vehicle and the opponent vehicle are running.

Also, in the lane change mode, the simulator controller 30 can recognize the start of lane change when there is an operation on the turn signal lamp 14 and recognize the lane change end when the turn signal 14 returns to the initial position. The lane change arrow 24 can be displayed when the operation of the turn signal lamp 14 is made.

Further, when the handle 15 rotates more than a predetermined angle with respect to the initial position, the vehicle position 25 of the driver can be gradually moved in the rotational direction of the handle 15. [ When the lane change mode is applied, the simulation system for determining the operation possibility according to the present invention may not be started according to the precondition for operation, and the operation of the steering wheel 15 may be difficult. Therefore, the simulator controller 30 recognizes the initial position of the steering wheel 15, and when the steering wheel 15 is rotated over a predetermined angle on the basis of the initial position, the driver can recognize the lane change by the simulator controller 30 . In addition, a tilt sensor may be provided on the handle 15 to recognize the lane change.

After completion of the lane change mode, the result of the lane change is displayed. Whether the lane change is complete, whether the lane change is sufficiently secured with respect to the relative vehicle position 26, and the like can be reflected and displayed in the performance result. In addition, these lane change modes can be used together in the reaction time test mode or the scenario execution mode, and the result of the performance can be numerically expressed and displayed as a score.

Accordingly, it is possible to determine how accurately the driver who is actually on the lane can perform the lane change under various conditions by using the simulation system for judging the possibility of operation according to the present invention, so that the possibility of operation of the actually riding driver can be determined.

Perform the scenario mode

4 is a view showing an embodiment of a scenario execution mode in a simulation system for determining the operation possibility according to the present invention.

In the scenario execution mode, the above-described simulator controller 30 controls the number of lane departure times, the number of times of collision, the running time, the number of violation of the rule, the reaction time, and the number of times of instruction failure while completing to the destination according to the scenario displayed on the head- You can analyze the completeness capabilities that you include.

The head-up display 20 of FIG. 4 displays a screen such as an actual road running, and shows a scenario in which the virtual vehicle 28 travels with the driver's vehicle. At the lower end of the head-up display 20, vehicle running information such as the driver's vehicle speed, whether the vehicle is abnormal or not is displayed.

After completion of the scenario execution mode, the execution result is displayed, and the completion capability evaluation indexes shown above can be reflected and displayed in the execution result. In addition, performance results can be numerically expressed and displayed as a score. If the result is below a certain score, it can be indicated that the current operation is dangerous.

Accordingly, by using the simulation system for judging the operation possibility according to the present invention, it is possible to grasp how accurately the driver who is actually on board can perform a scenario in which various situations are presented, so that it is possible to determine the operation possibility of the actual boarding driver.

A simulation method for determining the operation possibility according to the present invention will be described with reference to FIG. 5 is a flowchart showing a simulation method for determining the operation possibility according to the present invention.

A simulation method for determining an operation possibility according to the present invention includes: a first step of determining whether an operation of a simulation system is enabled in a simulator controller; A second step of displaying a selected simulation mode among a plurality of predetermined simulation modes in the head-up display when the simulator system is operable, and controlling the simulation mode in association with the vehicle running manipulator in the simulator controller; And a third step of displaying a result of the simulation mode in the head-up display when the selected simulation mode ends.

Each simulation mode can be started and ended with voice or button, and the driver can be forcibly terminated during execution of the simulation mode. In the entire operation process, a guidance message for the driver who is unfamiliar with the simulation method according to the present invention can be displayed in the head-up display, and the simulator controller can provide guidance voice in connection with in-vehicle sound equipment.

First of all, the simulator controller judges whether the simulation system is operable. Specifically, it checks whether the engine is started or not and analyzes the signal received from the tilt sensor to determine whether the vehicle is on a sloping road and whether a hand brake is applied It can be judged. In other words, it is preferable that the above-described judgment process is performed in the simulator controller so that the simulation system can operate in safety or optimum condition of the driver.

When it is determined that the operation of the simulator system is possible, the head-up display displays the selected simulation mode among a plurality of predetermined simulation modes, and the simulator controller controls the corresponding simulation mode in conjunction with the vehicle-running operation device. In this case, a plurality of predetermined simulation modes may include a reaction time test mode, a lane change mode, and a scenario execution mode, and may continuously update to provide more various modes.

Specifically, in the reaction time test mode, the head-up display displays one or more marks associated with vehicle driving. The driver who has seen the marked mark shows the corresponding response. The reaction time of the driver can be analyzed by the simulator controller to grasp the current state of the driver. For example, if the head-up display shows a mark related to the U-turn, the driver manipulates the steering wheel while controlling the speed to turn on the vehicle. At this time, the simulator controller comprehensively analyzes the response time of the steering wheel operation, the reaction to reduce the speed, etc., to find out the operation possibility of the driver. The head-up display can be displayed either immediately or at a later time. It is preferable to display the time at which the driver and the average driver react to the displayed mark at the same time. Thereafter, the results of the reaction time test mode analyzed based on the driver's reaction time with respect to a plurality of mark displays are displayed in various forms so that the driver can confirm the results.

The lane change mode first displays the driver's vehicle position, opponent vehicle position, and lane through the head-up display. If there is an operation on the turn signal lamp in this state, the simulator controller recognizes the start of the lane change and judges whether there is any operation on the steering wheel, the accelerator pedal or the brake pedal, and displays the result on the head-up display. That is, when the steering wheel is not started, the handle operability may deteriorate. Therefore, when the steering wheel rotates more than a predetermined angle with respect to the initial position, the simulator controller recognizes that the driver is performing the lane change. The position of the driver's vehicle gradually moves in the direction of rotation of the handle. By operating the accelerator pedal or the brake pedal together, the distance between the opponent's vehicle position and the driver's vehicle position can be appropriately maintained. When the turn signal lamp returns to the initial position, the simulator controller recognizes the end of the lane change. Then, the result of the lane change mode is displayed in various forms so that the driver can check it.

The scenario execution mode is a mode in which the driver must finish to the destination according to the scenario displayed on the head-up display. During running, the simulator controller analyzes the ability to complete lane departure times, number of collisions, completion time, number of violations, response time, and number of instructions failures. After completion of the process to the destination, the execution result of the scenario execution mode is displayed in various forms so that the driver can check it.

At this time, when the selected simulation mode ends, the head-up display displays a sign indicating the current position of the operating device and returning to the initial position, thereby preventing an abnormal operation of the vehicle.

Although the present invention has been shown and described with respect to certain embodiments thereof, it will be understood by those of ordinary skill in the art that various changes in form and details may be made therein without departing from the spirit and scope of the invention as defined by the following claims. It will be possible.
