In addition, the angle of the combiner panel 510 in the pop-up mode can be set according to the driver's preference by using the combiner angle adjusting unit 60.

The switching from the pop-up mode to the sleep mode is the reverse order of the above-described procedure, so a detailed description will be omitted.

The swing arm driving motor 301 is rotated by the first swing arm stoppers 203a and 203b against the first guide surface stoppers 103a and 103b while the swing arm 20 is moving in the other direction And the swing arm drive motor 301 stops rotating the swing arm drive gear 302. As a result,

In addition, in response to a signal generated by pressing the position sensor 107 while the panel holder 520 is in the sleep mode, the combinational driving motor 401 rotates the first combinational driving gear 402 And the combiner unit 50 stops rotating to be placed in the sleep mode.

Hereinafter, a control method of the head-up display device for a vehicle according to the embodiment of the present invention will be described.

13 is a block diagram showing a control configuration of a head-up display device for a vehicle according to an embodiment of the present invention.

13, the head-up display device for a vehicle according to the embodiment of the present invention includes a swing arm driving motor 301, a combiner driving motor 401 and a position sensor 107, A control unit 702, and a storage unit 703.

The current value measuring unit 701, the control unit 702 and the storage unit 703 are preferably provided inside the mounting unit 10.

The current value measuring unit 701 is electrically connected to the swing arm driving motor 301 and the combinator driving motor 401 to measure current values of the swing arm driving motor 301 and the combinator driving motor 401 .

The storage unit 703 stores the swing arm stall current value and the combiner stall current value. The swing arm stall current value and the combiner stall current value may be preset values according to specifications of the swing arm drive motor 301 and the combiner drive motor 401. [

The control unit 702 is electrically connected to the swing arm drive motor 301, the combinational drive motor 401, the current value measurement unit 701, the storage unit 703, and the position sensor 107.

The control unit 702 compares the measurement result of the current value measuring unit 701 with the swing arm stall current value and the combiner stall current value stored in the storage unit 703, And the motor 401, respectively.

More specific functions that the current value measuring unit 701 and the control unit 702 take in the control of the head-up display apparatus for a vehicle according to the embodiment of the present invention will be described later.

A control method of a head-up display apparatus for a vehicle according to an embodiment of the present invention includes a combinator pop-up control method and a combiner slip control method.

14 is a flowchart showing a combiner pop-up control method in a method of controlling a head-up display device for a vehicle according to an embodiment of the present invention.

As shown in FIG. 14, the method for controlling the combinator pop-up includes the steps of receiving a driving start signal (S10), sliding the swing arm in one direction (S20), rotating the combiner unit in one direction And placing the combiner unit in a pop-up mode (S40).

14 shows that the swing arm is slid in one direction (S20) and the combiner unit is rotated in one direction (S30) in parallel as an example of the combiner pop-up control method, Steps S20 and S30 may be sequentially performed in a manner that the operation precedes the step S30 or the operation S30 is preceded by the operation S20.

In the step S10 of receiving the drive start signal, the control unit 702 receives the drive start signal. The drive start signal may be a signal that turns on the vehicle or a signal that turns on a separate head-up display operation switch (not shown) provided in the vehicle.

The control unit 702 applies a voltage to the swing arm driving motor 301 to rotate the swing arm driving motor 301 in one direction so as to move the swing arm 20 to the mounting unit (See Fig. 11).

In the step S30 of rotating the combiner unit in one direction, the control unit 702 applies a voltage to the combiner driving motor 401 to rotate the combiner driving motor 401 in one direction, (See Fig. 11).

Hereinafter, for convenience of explanation, the direction in which the swing arm drive motor 301 and the combiner drive motor 401 rotate in the pop-up mode is referred to as forward rotation or forward direction.

The step S40 of placing the combiner unit in the pop-up mode is performed by the control unit 702 and the current value measuring unit 701 so that the combiner unit stops in the pop-up mode. And includes the steps as shown in Figs. 15A and 15B as a step in which the binar drive motor 401 is controlled.

15A and 15B are flowcharts showing in detail the step (S40) of placing the combiner unit in the pop-up mode.

As shown in FIGS. 15A and 15B, the step (S40) of placing the combiner unit in the pop-up mode includes a step S41 of rotating the swing arm driving motor S, a step of collecting a current value of the swing arm driving motor (S42), comparing the current value of the swing arm drive motor with the swing arm stall current value (S43), stopping the swing arm drive motor (S44), rotating the combiner drive motor (S45) A step S46 of collecting a current value of the motor drive motor, a step S47 of comparing the current value of the motor drive motor with a motor stall current value, and a step of stopping the motor drive motor S48).

The steps S41 to S44 shown in FIG. 15A may be performed in parallel with the steps S45 to S48 shown in FIG. 15B.

If steps S20 and S30 are sequentially performed, steps S41 to S44 shown in FIG. 15A and steps S45 to S48 shown in FIG. 15B may be sequentially performed.

The step S41 of forward rotating the swing arm drive motor is a step performed continuously in connection with the step S20 of sliding the swing arm in one direction.

FIG. 16 is a flowchart showing details of step S41 of forward rotation of the swing arm drive motor, and FIG. 17 is a graph representation of the steps shown in FIG.

As shown in Fig. 16, the step S41 of forward rotation of the swing arm driving motor includes a step S41a of raising the motor rotational speed, a step S41b of keeping the motor rotational speed constant, (S41c).

The step S41a of raising the motor rotational speed corresponds to the acceleration period of Fig. 17, and the step S41b of maintaining the motor rotational speed at a constant level corresponds to the constant velocity section of Fig. 17, S41c correspond to the deceleration section of Fig.

The control unit 702 starts to swing the swing arm 20 after the time t1 to rotate the swing arm driving motor 301 in the step S20 of sliding the swing arm in one direction, The rotational speed of the swing arm driving motor 301 is raised by the time t2 when the rotational speed of the swing arm driving motor 301 reaches the predetermined rotational speed RMP1 (S41a)

The acceleration interval may be set in such a manner that the time interval between t2 and t1 is set in advance or RMP1 is set in advance.

After the step S41a of raising the motor rotational speed is completed, the control unit 702 maintains the rotational speed of the swing arm driving motor 301 constant for a predetermined time (t2 to t3) (S41b).

After reaching the time t3, the control unit 702 decreases the rotation speed of the swing arm driving motor 301. [

The time t2-t1 of the acceleration section, the time t3-t2 of the constant velocity section and the time t4-t3 of the deceleration section are converted from the sleep mode to the pop-up mode, Can be set in advance.

The swing arm driving motor 301 is controlled in the order of acceleration, constant speed and deceleration to drive the swing arm 20 and the swing arm driving unit 30 The durability of each component can be increased and the noise caused by friction or collision between components can be reduced.

When a DC motor is used as the swing arm driving motor 301, the controller 702 can adjust the rotational speed of the swing arm driving motor 301 through a pulse width modulation (PWM) control method. This can shorten the combiner's pop-up time and reduce the noise generated during the pop-up process.

FIG. 18 is a view showing a PWM control method for the swing arm driving motor in the acceleration section of FIG. 17, FIG. 19 is a view showing a PWM control method for the swing arm driving motor in the constant speed section of FIG. 17, 17 is a diagram showing a PWM control method for the swing arm drive motor in the deceleration section of Fig.

18 to 20, the control unit 702 controls the rotation speed of the swing arm driving motor 301 by applying a pulse voltage of a predetermined period T to the swing arm driving motor 301.

In step S41a of raising the motor rotational speed, the controller 702 applies a pulse voltage gradually increasing in the order of the pulse widths t _a1 , t _a2 and t _a3 to the swing arm driving motor 301, 301 can be gradually increased.

Rotation of the step (S41b) The control unit 702 is arm swing by applying a pulse voltage is held to the pulse width constant at t _b to a swing arm drive motor 301, drive motor 301 to maintain the motor speed constant, The speed can be kept constant.

In step S41c of reducing the motor rotational speed, the controller 702 applies a pulse voltage whose pulse width gradually decreases in the order of t _c1 , t _c2 , t _c3 to the swing arm drive motor 301, 301 can be gradually reduced. The controller 702 may control the rotation speed to be gradually decreased by the rotational inertia and the friction of the swing arm driving motor 301 by applying a pulse voltage whose pulse width gradually decreases for a predetermined time and interrupting the voltage supply.

The time t2-t1 of the acceleration section, the time t3-t2 of the constant velocity section and the time t4 of the deceleration section are calculated by accurately estimating the moving distance of the swing arm 20 according to the rotational speed of the swing arm driving motor 301 the second swing arm stoppers 204a and 204b formed on the sliding surface 201 of the swing arm 20 are also rotated at the same time that the step S41c of reducing the motor rotational speed is finished, 5) and the second guide surface stoppers 104a and 104b (see FIG. 3) formed on the arc-shaped guide surface 102 are in contact with each other and the swing arm can be placed in the pop-up mode.

However, since such control is considerably difficult in reality, it is sensed that the second swing arm stoppers 204a and 204b and the second guide surface stoppers 104a and 104b are in contact with each other while the swing arm 20 is moving in one direction The swing arm driving motor 301 must be stopped.

To this end, the method for controlling a head-up display apparatus for a vehicle according to an embodiment of the present invention uses the current value of the swing arm driving motor 301 to control the movement of the second swing arm stoppers 204a and 204b and the second guide surface stoppers 104a and 104b, The contact state is detected by the method of detection.

21 is a graph showing a current value according to a load state of the swing arm driving motor.

As shown in FIG. 21, while the swing arm driving motor 301 moves the swing arm 20 in one direction, the current value of A1 is measured by the swing arm driving motor 301. However, from moment t2 when the second swing arm stoppers 204a and 204b contact the second guide surface stoppers 104a and 104b, a load is applied to the swing arm driving motor 301 and the current of the swing arm driving motor 301 When the swing arm 20 is in a stall state until the second swing arm stoppers 204a and 204b and the second guide surface stoppers 104a and 104b are pressed against each other, The current value of the arm drive motor 301 rises sharply to A2.

In the method of controlling a head-up display apparatus for a vehicle according to the present invention, the value A2 is referred to as a stall current value of the swing arm driving motor 301, and controls the swing arm 20 to be positioned in a pop-up mode.

15A, in the step S42 of collecting the current value of the swing arm driving motor, the current value measuring unit 701 measures the current value of the swing arm driving motor 301 during the forward rotation of the swing arm driving motor 301, Is measured and collected.

In the step S43 of comparing the current value of the swing arm drive motor with the current value of the swing arm stall current, the control unit 702 compares the current value of the swing arm drive motor 301 collected by the current value measurement unit 701 in real time And compares it with the swing arm stall current value (A2). The swing arm stall current value A2 may be input to the storage unit 703 in advance.

When the current value of the swing arm driving motor 301 collected by the current value measuring unit 701 is lower than the swing arm stall current value A2, the control unit 702 sets the rotating speed of the swing arm driving motor 301 to The control is performed in the order of acceleration, constant speed, and deceleration according to a predetermined procedure. Alternatively, the deceleration step may be omitted and controlled in the order of acceleration and constant velocity. Alternatively, the acceleration step can be omitted and controlled in the order of constant speed and deceleration. Or, the acceleration and deceleration steps may be omitted and the constant velocity control may be performed.

However, when the current value of the swing arm driving motor 301 collected by the current value measuring unit 701 reaches the swing arm stall current value A2 or is larger than the swing arm stall current value A2, the controller 702 Stops applying the pulse voltage to the swing arm driving motor 301 and stops the swing arm driving motor 301 (S44). As the control unit 702 stops the swing arm driving motor 301, the one-way sliding of the swing arm 20 also stops.

In order to minimize the impact between the swing arm 20 and the mounting unit 10 and the impact acting on the swing arm driving unit 30, the current value of the swing arm driving motor 301 is equal to or greater than the swing arm stall current value A2 Is preferably generated when the swing arm drive motor 301 is in the deceleration stage.

By the above-described control, the swing arm 20 is stably positioned in the pop-up mode. Further, since the swing arm driving motor 301 is controlled using the current value of the swing arm driving motor 301, it can be detected that the swing arm 20 is stalled before the swing arm 20 is placed in the pop-up mode.

On the other hand, the step S45 of rotating the combiner drive motor shown in FIG. 15B is similar to the step S41 of rotating the swingarm drive motor in the forward direction.

16 and 17, the control unit 702 includes a step (S45a) of raising the motor rotation speed of the combiner drive motor, a step (S45b) of keeping the motor rotation speed constant and a step (Step S45c).

The method of controlling the speed of the combinational driving motor 401 may also be performed by the method shown in FIGS. 18 to 20, similarly to the method of controlling the speed of the swing arm driving motor 301. That is, a DC motor may be used as the combiner driving motor 401, and the controller 702 may control the rotation speed of the combiner driving motor 401 through a pulse width modulation (PWM) . A detailed description thereof will be omitted in order to omit redundant description.

In addition, the combiner drive motor 401 can also be stopped based on the current value of the combiner drive motor 401. [ That is, when the combiner unit 50 is rotated in one direction by using the current value of the combiner driving motor 401, the end of the pressing terminal 602 is in contact with one surface of the panel holder 520 .

Will be described with reference to FIG. 21 for convenience of explanation.

The current value of A1 is measured in the combiner drive motor 401 while the combiner drive motor 401 rotates the combiner unit 50 in one direction. However, from moment t2 when the end of the pressing end 602 contacts one side of the panel holder 520, a load is applied to the combinational driving motor 401 and the current value of the combinational driving motor 401 rises And the current value of the combiner driving motor 401 is set to A2 (t3) when the pressing terminal 602 and the panel holder 520 are pressed against each other and the combiner unit 50 is stalled . 21 for convenience of explanation, the current values of A1 and A2 may be different from those of the swing arm driving motor 301. [

In the step S46 of collecting the current value of the combinational driving motor shown in Fig. 15B, the current value measuring unit 701 measures the current value of the combinator driving motor 401) is measured and collected.

In the step S47 of comparing the current value of the combiner drive motor with the value of the combiner stall current shown in Fig. 15B, the control unit 702 controls the combiner drive motor 701, which is collected by the current value measuring unit 701, The current value of the stator 401 is compared with the stator current value A2 in real time. The combiner stall current value A2 may be input to the storage unit 703 in advance.

When the current value of the combinational drive motor 401 collected by the current value measurement unit 701 is lower than the combinator stall current value A2, The rotation speed is controlled in the order of acceleration, constant speed, and deceleration according to a predetermined procedure. Alternatively, the deceleration step may be omitted and controlled in the order of acceleration and constant velocity. Alternatively, the acceleration step can be omitted and controlled in the order of constant speed and deceleration. Or, the acceleration and deceleration steps may be omitted and the constant velocity control may be performed.

However, when the current value of the combiner drive motor 401 collected by the current value measuring unit 701 reaches the combiner stall current value A2 or is larger than the combiner stall current value A2, The control unit 702 stops applying the pulse voltage to the combinational driving motor 401 to stop the combinational driving motor 401 (S48). As the control unit 702 stops the combinational driving motor 401, the unidirectional rotation of the combinator unit 50 also stops.

In order to minimize the impact between the combiner unit 50 and the combiner angle adjusting unit 60 and the impact acting on the combiner driving unit 40, It is preferable that the timing at which the binner stall current value A2 becomes equal to or higher than the binener stall current value A2 occurs when the combiner drive motor 401 is in the deceleration stage.

By the above-described control, the combiner unit 50 is stably placed in the pop-up mode. In addition, since the combiner driving motor 401 is controlled by using the current value of the combiner driving motor 401, it is also possible to detect that the combiner unit 50 is stalled before the combiner unit 50 is placed in the pop-up mode .

Hereinafter, a method for controlling a subscriber slip of a method for controlling a head-up display apparatus for a vehicle according to an embodiment of the present invention will be described.

FIG. 22 is a flowchart illustrating a method of controlling a controller sleep in a method of controlling a head-up display device for a vehicle according to an embodiment of the present invention.

As shown in FIG. 22, the method for controlling the slip of the combiner includes a step of receiving a drive stop signal (S50), a step of sliding the swing arm in the other direction (S60), a step of rotating the combiner unit (S70) and placing the combiner unit in the sleep mode (S80).

22, the swing arm is slid in the other direction (S60) and the combiner unit is rotated in the other direction (S70). However, in S60 The steps S70 and S70 may be sequentially performed in such a manner that the step precedes the step S70 or the step S70 precedes the step S60.

In the step S50 of receiving the drive stop signal, the controller 702 receives the drive stop signal. The driving stop signal may be a signal for turning off the vehicle or a signal for turning off a separate head-up display operation switch (not shown) provided in the vehicle.

The control unit 702 applies a voltage to the swing arm driving motor 301 to rotate the swing arm driving motor 301 in the other direction so as to swing the swing arm 20 in the opposite direction And slides in a downward direction with respect to the mounting unit 10. [

The voltage applied to the swing arm driving motor 301 by the control unit 702 in the case where the swing arm driving motor 301 is a motor capable of normal / The reverse voltage may be a reverse voltage of the voltage applied to the gate electrode 301.

Therefore, in the combiner slip control method, the swing arm driving motor 301 rotates in the opposite direction to the swing arm driving motor 301 in the combinator pop-up control method.

The control unit 702 applies a voltage to the combiner driving motor 401 to rotate the combiner driving motor 401 in the other direction so as to rotate the combiner driving motor 401 in the opposite direction, And rotates the knurled unit 50 toward the mounting unit 10.

The voltage applied to the combiner driving motor 401 by the control unit 702 is the same as the voltage applied to the combiner driving motor 401 in the step S30 of rotating the combiner unit in one direction And may be a reverse voltage of the voltage applied to the combiner drive motor 401. [

Therefore, in the combiner slip control method, the rotation direction of the combinational drive motor 401 is opposite to the rotation direction of the combinational drive motor 401 in the combinator pop-up control method.

Hereinafter, for the convenience of explanation, the direction in which the swing arm drive motor 301 and the combinator drive motor 401 rotate in the sleep mode is referred to as reverse rotation or reverse direction.

The step S80 of placing the combiner unit in the sleep mode is performed by the control unit 702 and the current value measuring unit 701 so that the combiner unit stops in the sleep mode. And includes the steps as shown in Figs. 23A and 23B as a step in which the binar drive motor 401 is controlled.

23A and 23B are flowcharts showing in detail the step (S80) of placing the combiner unit in the sleep mode.

As shown in FIGS. 23A and 23B, the step S80 of placing the combiner unit in the sleep mode includes a step S81 of reversing the swing arm driving motor, a step of collecting a current value of the swing arm driving motor (S82), comparing the current value of the swing arm driving motor with the swing arm stall current value (S83), stopping the swing arm driving motor (S84), reversing the combinator driving motor (S85) A step S86 of collecting a current value of the combinational driving motor, a step S87 of comparing the current value of the combinational driving motor with a value of the combinational stoichiometric current, and a step of stopping the combinational driving motor S88).

A step S82 of reversing the swing arm driving motor S81, a step S82 of collecting a current value of the swing arm driving motor, a step S83 of comparing the swing arm stall current value with the current value of the swing arm driving motor, A step S84 of stopping the arm driving motor, a step S85 of reversing the combinational driving motor, a step S86 of collecting a current value of the combinational driving motor, Step S87 of comparing the stator current values of the combiners and step S88 of stopping the combinational driving motor include steps S41 to Sw4 of the swingarm driving motor of the above-described combinator pop-up control method, A step S42 of comparing the current value of the arm drive motor with a current value of the swing arm drive motor, a step S44 of stopping the swing arm drive motor, (S45) of forward rotation of the drive motor, the current (S46), comparing the current value of the combiner drive motor with the value of the combiner stall current (S47), and stopping the combiner drive motor (S48) The voltage applied to the swing arm driving motor 301 by the control unit 702 and the voltage applied to the combinational driving motor 401 are compared with each other, In the case of the pop-up control method, it is distinguished in that it is the reverse voltage of the applied voltage.

When the stator current value is generated in the swing arm driving motor 301 in the combinational slip control method, the first swing arm stoppers 203a and 203b and the first guide surface stoppers 103a and 103b are pressed against each other, And is distinguished in that the arm 20 is in a stall state.

When the stator current value is generated in the combiner driving motor 401 in the combiner slip control method, the panel holder 520 is pressed against the mounting unit 10 to cause the combiner unit 50 to be stalled It is distinguished in that it is when it comes.

On the other hand, the position sensor 107 detects that the combiner unit 50 is positioned in the sleep mode.

The controller 702 electrically connected to the position sensor 107 controls the operation of the combiner unit 50 in the sleep mode through the electrical signal output from the position sensor 107 by pressing the position sensor 107 by the panel holder 520. [ As shown in FIG.

Therefore, the controller 702 controls the combiner unit 50 to operate in a state where both the factors of generating the stall current value in the combiner driving motor 401 and detecting the output value of the position sensor 107 It can be determined that it is located in the sleep mode.

If the stator current value is generated in the motor drive motor 401 but the output value of the position sensor 107 is not sensed, the controller 702 determines that the combiner unit 50 is normally in the sleep mode It can be judged that it has failed.

For example, in a state where a foreign substance is interposed between the mounting unit 10 and the combiner unit 50, a stall current value is generated in the combiner driving motor 401 due to the foreign substance, but the position sensor 107 And is not pressed by the panel holder 520.

Accordingly, when the stator current value is generated in the combiner driving motor 401 but the output value of the position sensor 107 is not detected, the control unit 702 can send a warning signal to the vehicle driver. The warning signal may be simply an audible beep sound, a signal indicating the presence of a foreign object or a sleep mode failure using a character image.

It will be understood by those skilled in the art that the present invention may be embodied in other specific forms without departing from the spirit or essential characteristics thereof. It is therefore to be understood that the above-described embodiments are illustrative in all aspects and not restrictive.
