Description

Driving control method for vehicle display

Technical Field

The present disclosure relates to a driving control method of a vehicle display.

Background

The display of the vehicle provides content according to the driving situation.

Recently, with the development of autonomous driving technology, an infotainment function in a vehicle is actively being developed, and thus a large-sized display should be driven in a separate manner to secure a visual field.

Thus, a method of selectively exposing the display may be applied, but when the method is applied, the device is likely to be damaged or malfunction when external force is applied to the display, for example, when the display is forcibly pressed, during the operation of the display.

In addition, when the user's hand is caught in the slit forming the movement path of the display, the user may be injured, and thus additional measures are required.

Disclosure of Invention

In order to solve the above-described problems, the present disclosure is directed to providing a driving control method for a display of a vehicle for driving and controlling the display of the vehicle according to a current value and/or an operation time with respect to external resistance (external force).

Aspects of the present disclosure are not limited thereto, and other aspects not mentioned herein will be apparent to those of ordinary skill in the art from the following description.

According to one aspect of the present disclosure, a driving control method of a vehicle display includes: receiving an input signal selected for an on mode or an off mode of a display of the vehicle, operating a driving motor of the display to move the display to a preset target position according to the input signal for each mode, and stopping the driving motor after the display reaches the preset target position, wherein the driving control method further includes detecting external resistance by measuring a current value of the driving motor between operating the driving motor and stopping the driving motor.

Detecting the external resistance includes detecting whether the current value of the driving motor is abnormal by comparing the measured current value of the driving motor with a preset reference current value, and determining that the external resistance is generated and urgently stopping the driving motor when the measured current value of the driving motor is greater than the preset reference current value.

Operating the driving motor may further include a reset operation for operating the driving motor that is emergency stopped when external resistance is detected, to receive a preset initial position input signal of the display, and to move the display to the initial position.

In the reset operation, the preset initial position may be a start position in the open mode or the closed mode.

The emergency stop driving motor may include: the emergency stop driving motor is preset for a time and transmits a warning notification message to an occupant in the vehicle of the current situation in the form of a screen and/or voice, and transmits the warning notification message to the server to store the warning notification message in the server.

Stopping the driving motor may include: the target position in each mode is detected by detecting the target position of the display via an open switch or a close switch located at an end point in each mode, and the driving motor is stopped after the target position of the display is detected by the open switch or the close switch.

According to another aspect of the present disclosure, a driving control method of a vehicle display includes: receiving an input signal selected for an on mode or an off mode of a display of the vehicle, operating a driving motor of the display to move the display to a preset target position according to the input signal for each mode, and stopping the driving motor after the display reaches the preset target position, wherein the driving control method further includes detecting external resistance by measuring the number of revolutions of a gear of the driving motor between operating the driving motor and stopping the driving motor.

According to another aspect of the present disclosure, a driving control method of a vehicle display includes receiving an input signal selected for one of an on mode and an off mode of the vehicle display, operating a driving motor of the display to move the display to a preset target position according to the input signal for each mode, and stopping the driving motor after the display reaches the preset target position, wherein the driving control method further includes detecting external resistance by measuring a current value of the driving motor and/or a number of revolutions of a gear of the driving motor between operating the driving motor and stopping the driving motor.

First embodiment (basic Structure)

Fig. 1 is a front view schematically illustrating a display device for a vehicle according to a first embodiment of the present disclosure.

Referring to fig. 1, a display device 1000 for a vehicle according to a first embodiment of the present disclosure includes a screen unit 1100, a driving unit 1200, and a control unit 1300.

The screen unit 1100 outputs vehicle operation information and images of respective functions. The screen unit 1100 is a large screen display whose basic size and performance exceeds those of an existing display (not shown) that provides only vehicle operation information.

That is, when the autonomous mode widely used due to the development of technology is used, the screen unit 1100 may provide more comfortable and convenient information (e.g., infotainment information, etc.) in the form of an image to the occupant.

However, when the occupant does not use autonomous driving but has to drive the vehicle by himself, the large screen of the screen unit 1100 may obstruct the view of the occupant, thereby posing a risk of a safety accident.

Accordingly, the screen unit 1100 of the present disclosure may provide convenience of a large screen in an autonomous driving mode (an on mode), and control the exposure of the screen in a driving mode (an off mode) to secure a driver's view.

Accordingly, the position of the screen unit 1100 is adjusted by the driving unit 1200 to selectively control the exposure range of the display area, and a predetermined image may be output according to the exposure range of the display area.

The driving unit 1200 adjusts the position of the screen unit 1100 by rotating the pop-up.

The control unit 1300 may control driving of the driving unit 1200 by a predetermined command or manipulation of a switch. The control unit 1300 may have control logic limited to a corresponding function or may be an Electronic Control Unit (ECU) of the vehicle.

First embodiment (operating mechanism)

Fig. 2 to 11 illustrate the relationship between the components of the display device for a vehicle according to the first embodiment of the present disclosure and the operations of the components.

Referring to fig. 2 and 3, the position of the screen unit 1100 above the second rack 1270 may be adjusted by the driving unit 1200. Here, when the screen unit 1100 moves in the positive Y-axis direction between the first rack 1250 of fig. 1 and the second rack 1270 of fig. 2 and 3, the screen unit 1100 may enter the open mode.

In contrast, when the screen unit 1100 moves in the negative Y-axis direction between the first rack 1250 of fig. 1 and the second rack 1270 of fig. 2 and 3, the screen unit 1100 may enter the off mode.

Referring to fig. 4, as a basic function, the driving unit 1200 transmits driving force to the rotating shaft 1230 through the actuator 1210 such that the first pinion 1240 connected to one end of the rotating shaft 1230 is engaged with the first rack 1250 while rotating together with the rotating shaft 1230.

Accordingly, the rotation shaft 1230 rotates in a direction of transmitting the driving force from the actuator 1210, so that the first pinion 1240 rotated together with the rotation shaft 120 moves while being engaged with the first rack 1250.

When the first pinion 1240 rotates in the positive Y-axis direction, the cover 1220 connected to the screen unit 1100 of fig. 1 to 3 moves in the positive Y-axis direction along the path of the first rack 1250.

Referring to fig. 5 and 6, the actuator 1210 includes a housing 1211, a drive motor 1212, a bevel gear 1214, a spur gear 1215, an open switch 1216, and a close switch 1217.

The case 1211 is located above the rotation shaft 1230 while being connected to the rear surface of the screen unit 1100.

The drive motor 1212 is located within a housing 1211, having a drive shaft 1213.

The bevel gear 1214 is connected to the drive shaft 1213 for rotation with the drive shaft 1213.

The spur gear 1215 includes a first serration 1215a that rotates with the helical gear 1214 and a second serration 1215b that rotates with the first serration 1215a and is connected to the rotating shaft 1230.

An open switch 1216 is located at an upper end of the housing 1211, and detects an open position of the screen unit 1100.

The closing switch 1217 is located at a lower end of the housing 1211, and detects a closing position of the screen unit 1100.

The actuator 1210 may detect the current position of the screen unit 1100 through a magnet 1218 connected to the second saw tooth 1215b and a magnet sensor 1219 located in the region of the housing 1211 and detecting the number of rotations of the magnet 1218.

As another example, as shown in fig. 7, the actuator 1210' may include an on switch 1216, an off switch 1217, a magnet 1218, and a magnet sensor 1219 so as to be stably driven.

When the reset is activated by a user through a separate switch (not shown) and/or a predetermined command, the driving unit 1200 moves the screen unit 1100 in the direction of the off mode or the on mode.

Accordingly, the opening switch 1216, the closing switch 1217, the magnet 1218, and the magnet sensor 1219 can detect the current reset position of the screen unit 1100.

In fig. 8, the screen unit 1100 is in the off mode, and thus only images of relatively simple information about the vehicle speed, the operation direction, and the sound source are output.

On the other hand, in fig. 9, the screen unit 1100 is in an open mode and thus outputs an image of a combination of vehicle operation information and entertainment information through a plurality of Graphical User Interfaces (GUIs).

In fig. 10 and 11, the display device 1000' for a vehicle includes a first hook 1110 and a second hook 1120 to ensure rigidity.

The first and second hooks 1110 and 1120 may be provided at front and rear sides of the screen unit 1100, respectively, and the first and second hooks 1110 and 1120 are snap-fastened with the cockpit module 10 when the screen unit 1100 is switched to the open state.

For example, the first hook 1110 may be fixed on the lower fixed end 12 of the cockpit module 10, and the second hook 1120 may be fixed on the upper fixed end 11 of the cockpit module 10.

Second embodiment (basic Structure and operating mechanism)

Fig. 12 to 15 illustrate the relationship between the components of the display device for a vehicle according to the second embodiment of the present disclosure and the operations of the components.

First, referring to fig. 12 and 13, the display device 200 for a vehicle according to the second embodiment includes a screen unit 2100 and a driving unit 2200.

The screen unit 2100 outputs a corresponding image according to a closed mode in which some areas of the screen unit 2100 are exposed on the cockpit module 10 or an open mode in which all areas of the screen unit 2100 are exposed on the cockpit module 10.

In this case, the position of the screen unit 1100 is adjusted by the driving unit 2200 to selectively control the exposure range of the display area, and a predetermined image may be output according to the exposure range of the display area.

The driving unit 2200 may adjust the position of the screen unit 2100 according to a pattern while rotating in the cockpit module 10 according to a predetermined logic.

The driving unit 2200 includes an actuator 2210, a connection bar 2220, and a hinge shaft 2230.

The actuator 2210 has a drive shaft (not shown).

The connection lever 2220 is connected between the driving shaft and the screen unit 2100.

The hinge shaft 2230 connects the driving shaft of the actuator 2210 and the connection bar 2220.

The hinge shaft 2230 may be fixed at a predetermined angle to adjust the position of the screen unit 2100.

The screen unit 2100 may further include first and second hooks 2110 and 2120 at front and rear sides thereof to be snap-fastened with the cockpit module 10 in an open mode, thereby securing rigidity.

According to the present disclosure, the display apparatus for a vehicle can selectively control the exposure of the display area of the screen unit, thereby ensuring convenience and safety.

In particular, according to the present disclosure, different operation information and infotainment information may be provided according to the exposure degree of the display area of the screen unit.

In addition, according to the present disclosure, durability can be maintained by using the reinforcing structure of the hook portion when shaking occurs due to an external force.

The present disclosure is not limited to the above-described embodiments and may be implemented in various forms within the allowable scope of the technical idea of the present disclosure.

Driving control method for vehicle display

Fig. 16 and 17 are flowcharts of a driving control method of a vehicle display according to an embodiment of the present disclosure.

In fig. 16 and 17, the driving control method of the vehicle display mainly includes receiving an on/off mode input signal (S110), operating a driving motor (S120), detecting external resistance by measuring a current value (S130), and stopping the driving motor (S140).

Receiving an on/off mode input signal (S110) includes receiving an input signal selected for one of an on mode (e.g., autonomous driving mode) and an off mode (e.g., normal driving mode) of a vehicle display.

The operation of the drive motor (S120) includes: the drive motor of the display is operated to move the display to a preset target position according to the input signal for each mode.

Detecting the external resistance (S130) may include detecting the external resistance by measuring whether a current value of the driving motor is abnormal.

Stopping the driving motor (S140) may include stopping the driving motor after the display reaches a preset target position.

The above operation will be described in detail in terms of time with reference to fig. 17.

The basic concept of this embodiment is as follows. When the display is ejected according to the open or closed mode, when a load is applied to the driving motor due to an external force (external resistance), a current value of the driving motor is measured. Thereafter, when the measured current value does not fall within the range of the reference current value, it is determined that the load is applied (external resistance occurs) and thus the operation of the driving motor is stopped. After the operation of the drive motor is stopped, the drive motor is operated to move the display to the initial position in accordance with a reset input value (input) of a driver (including an occupant) of the vehicle.

As shown in fig. 17, when the driver sets the display to the on mode or the off mode according to the purpose, an input signal selected for the set mode is received (S110). For example, in operation S110, an input signal for the on mode is received when it is assumed that the driver sets the display to the on mode, and an input signal for the off mode is received when it is assumed that the driver sets the display to the off mode.

The driving motor is initially operated according to input signals for respective modes (S121). Next, a current value of the driving motor is measured to detect external resistance (S130). Detecting the external resistance (S130) may include detecting whether a current value of the driving motor is abnormal (S131) and emergency stopping the driving motor (S132).

Whether the current value of the driving motor is abnormal is detected by comparing the measured current value of the driving motor with a reference current value (S131). For example, in operation S131, when it is assumed that the driving motor has a problem (e.g., an over specification) at 250mA (reference current value) or more, the occurrence of external resistance is detected when the measured current value of the driving motor is greater than 250 mA.

When a situation that causes external resistance to occur is detected, that is, when the measured current value of the driving motor is greater than the reference current value, it is determined that external resistance occurs, and the driving motor is stopped urgently (S132).

In this case, the emergency stop driving motor (S132) may include transmitting a warning notification message and storing the warning notification message.

When the warning notification message is transmitted, the warning notification message is transmitted to the occupant in the vehicle of the present situation in the form of a screen and/or voice after the drive motor is emergently stopped for a preset time.

Storing the alert notification message includes sending the alert notification message to a server for storage in the server. This operation may be significant because the alert notification message may be used as big data in the future.

Immediately after the emergency stop of the driving motor (S132), the driving motor is operated twice (S122), and the display is moved to a preset initial position according to a preset initial position input signal of the display, so that the display is reset (S123).

As another example, when a certain time elapses or when the measured current value falls within the range of the reference current value, the drive motor that has been stopped urgently may be operated secondarily (S122).

The preset initial position of the reset display may be a starting position in an open or closed mode. This is because the display is reset to any one of the modes, and thus the driver can set the display to the on or off mode again to receive the corresponding operation signal (S110') or can end the drive control method.

For example, while the display is reset to the off mode, the driver wants to enter the on mode, and the driver should select the on mode to operate the drive motor again. That is, when an operation signal is received after one of the driver re-selection modes (S110'), the driving motor is operated a third time (S124).

After that, the current value of the driving motor is measured again to determine whether the current value is abnormal (S131'), and when it is determined that the current value is not abnormal, the driving motor moves to the target position, and the display reaching the target position is detected by opening or closing the switch (S141). When the position of the display is not detected by opening or closing the switch in operation S141, the driving motor is operated until the position of the display is detected. As a result, when the display reaches the target position, the driving motor is stopped (S142).

When the current value of the re-measured driving motor is abnormal, it is determined that the driving motor is still affected by the external force, and thus the driving motor is stopped urgently (S132), and the subsequent operation is performed.

Fig. 18 and 19 are flowcharts of a driving control method of a vehicle display according to another embodiment of the present disclosure.

In fig. 18 and 19, the driving control method of the vehicle display mainly includes receiving an on/off mode input signal (S210), operating a driving motor (S220), detecting external resistance using the number of rotations of a gear (S230), and stopping the driving motor (S240).

Receiving an on/off mode input signal (S210) includes receiving an input signal selected for one of an on mode (e.g., autonomous driving mode) and an off mode (e.g., normal driving mode) of the vehicle.

Operating the drive motor (S220) includes operating the drive motor of the display to move the display to a preset target position according to input signals for respective modes.

Detecting the external resistance (S230) may include detecting the external resistance by measuring whether the number of gear revolutions of the driving motor is abnormal.

Stopping the driving motor (S240) may include stopping the driving motor after the display reaches a preset target position.

The above operation will be described in detail in terms of time with reference to fig. 19.

The basic concept of this embodiment is as follows. When the display is ejected according to the open or closed mode, the number of revolutions per second of the gear of the drive motor is measured when a load is applied to the drive motor due to an external force (external resistance). Thereafter, when the revolution per second is less than the preset reference value, it is determined that the load is applied (external resistance is generated), and thus the operation of the driving motor is stopped. After stopping the operation of the drive motor, the drive motor is operated according to a reset input value (input) from a driver (including an occupant) of the vehicle to move the display to the initial position.

Referring to fig. 19, when the driver sets the display to an on or off mode according to the purpose, an input signal selected for the set mode is received (S210). For example, in operation S210, an input signal for the on mode is received when it is assumed that the driver sets the display to the on mode, and an input signal for the off mode is received when it is assumed that the driver sets the display to the off mode.

The driving motor is initially operated according to the input signals for the respective modes (S221). Next, the number of revolutions per second of the gear of the driving motor is measured to detect the external resistance (S230). Detecting the external resistance (S230) may include detecting whether the number of rotations of the gear of the driving motor is abnormal (S231) and emergency stopping the driving motor (S232).

The rotation number of the gear of the driving motor is compared with a preset reference value (reference rotation number) to detect whether the rotation number of the gear of the driving motor is abnormal (S231). For example, in operation S231, it is determined that external resistance occurs when the preset reference revolution per second of the driving motor is 10 and the measured revolution per second of the gear is 7 or less.

When a situation that causes the generation of external resistance is detected, that is, when the number of revolutions per second of the gear of the driving motor is less than the preset reference number of revolutions, it is determined that external resistance is generated and thus the driving motor is stopped urgently (S232).

In this case, the emergency stop driving motor (S232) may include transmitting a warning notification message and storing the warning notification message.

When the warning notification message is transmitted, the warning notification message is transmitted to the passenger in the vehicle of the current situation in the form of a screen and/or voice after the driving motor is emergently stopped for a preset time.

Storing the alert notification message includes sending the alert notification message to the server for storage in the server. This operation may be significant because the alert notification message may be used as big data in the future.

Immediately after the driving motor is stopped (S232), the driving motor is operated twice (S222), and the display is moved to a preset initial position according to a preset initial position input signal of the display, and the display is reset (S223).

As another example, when a certain time has elapsed or when the measured number of rotations of the gear is less than the reference value, the drive motor that has been stopped urgently may be operated secondarily (S222).

The preset initial position of the display in the reset state may be a starting position in the open mode or in the closed mode. This is because the display is reset to one of the on mode and the off mode, and thus the driver can set the display to the other mode again to receive the corresponding operation signal (S210') or can end the drive control method.

For example, when the driver wants to enter the on mode while the display is reset to the off mode, the driver should select the on mode again to operate the drive motor. That is, when an operation signal is received after the driver reselects one of the modes (S210'), the driving motor is operated a third time (S224).

After that, the number of revolutions per second of the gear of the driving motor is measured again to determine whether the number of revolutions of the gear is abnormal (S231'), and when it is determined that the number of revolutions is not abnormal, the driving motor moves to the target position and the display is detected to reach the target position by opening or closing the switch (S241). When the position of the display is not detected by opening or closing the switch in operation S241, the driving motor is operated until the position of the display is detected. When the display reaches the target position, the driving motor is stopped (S242).

When the re-measured revolution per second of the gear of the driving motor is abnormal, it is determined that the driving motor is still affected by the external force, and thus the driving motor is stopped urgently (S232) and a subsequent operation is performed.

Fig. 20 and 21 are flowcharts of a driving control method of a vehicle display according to another embodiment of the present disclosure.

In fig. 20 and 21, the driving control method of the vehicle display mainly includes receiving an on/off mode input signal (S310), operating a driving motor (S320), detecting external resistance by measuring a current value and/or the number of rotations of a gear (S330), and stopping the driving motor (S340).

Receiving an on/off mode input signal (S310) includes receiving an input signal selected for one of an on mode (e.g., autonomous driving mode) and an off mode (e.g., normal driving mode) of a vehicle display.

Operating the drive motor (S320) includes operating the drive motor of the display to move the display to a preset target position according to input signals for respective modes.

Detecting the external resistance (S330) may include detecting the external resistance by checking whether the measured current value of the driving motor and/or the number of revolutions of the gear of the driving motor are abnormal.

Stopping the driving motor (S340) may include stopping the driving motor after the display reaches a preset target position.

The above-described operation will be described in detail in terms of time with reference to fig. 21.

The basic concept of this embodiment is as follows. When the display is ejected according to the open or close mode, the current value of the drive motor and the number of revolutions per second of the gear of the drive motor are measured when a load is applied to the drive motor due to an external force (external resistance). Thereafter, when the measured current value does not fall within the range of the reference current value or the revolution per second of the gear is less than the preset reference value, it is determined that a load is applied (external resistance occurs), thereby stopping the operation of the driving motor. After stopping the operation of the drive motor, the drive motor is operated according to a reset input value (input) from a driver (including an occupant) of the vehicle to move the display to the initial position.

As shown in fig. 21, when the driver sets the display to the on or off mode according to the use, an input signal selected for the set mode is received (S310). For example, in operation S310, an input signal for an on mode is received when it is assumed that the driver sets the display to an on mode, and an input signal for an off mode is received when it is assumed that the driver sets the display to an off mode.

The driving motor is initially operated according to the input signals for the respective modes (S321). Next, a current value of the driving motor and/or the number of rotations of the gear is measured to detect external resistance (S330). Detecting the external resistance (S330) may include detecting whether a current value of the driving motor and/or the number of rotations of the gear is abnormal (S331) and emergency stopping the driving motor (S332).

Whether the current value of the driving motor and/or the number of rotations of the gear is abnormal is detected by comparing the measured current value of the driving motor with a reference current value and/or comparing the number of rotations of the gear with a parameter value (reference number of rotations) (S331). For example, in operation S331, when a problem (e.g., an out-of-specification) occurs on the assumption that the driving motor is at 250mA (reference current value) or more, the occurrence of external resistance is detected when the measured current value of the driving motor is greater than 250 mA. In addition, when the reference revolution per second of the drive motor is 10 and the measured revolution per second of the gear is 7 or less, the occurrence of external resistance is detected.

When a situation causing external resistance to occur is detected, that is, when the measured current value of the driving motor is greater than the reference current value or when the number of revolutions per second of the gear is less than the preset reference number of revolutions, it is determined that external resistance occurs, and thus the driving motor is stopped urgently (S332).

In this case, the emergency stop driving motor (S332) may include transmitting a warning notification message and storing the warning notification message.

Further, immediately after the driving motor is stopped in an emergency (S332), the driving motor is operated twice (S322), and the display is moved to a preset initial position according to a preset initial position input signal of the display to reset the display (S323).

As another example, when a certain time has elapsed, when the measured current value is greater than the reference current value, or when the revolution per second of the gear is less than the reference value (S322), the drive motor having been stopped urgently may be operated twice.

The preset initial position of the display after reset may be a starting position in an open or closed mode. This is because the display is reset to one of the on mode and the off mode, and thus the driver can set the display to the other mode again to receive the corresponding operation signal (S310') or can end the drive control method itself.

For example, when the driver wants to enter the open mode when the display is reset to the closed mode, the driver should reselect the open mode to operate the drive motor again. That is, when an operation signal is received after the driver reselects one of the modes (S310'), the motor is driven for a third operation (S324).

After that, the current value of the driving motor and/or the number of revolutions per second of the gear are measured again to determine whether the current value and/or the number of revolutions of the gear are abnormal (S331'), and when it is determined that the current value and/or the number of revolutions of the gear are normal, the driving motor moves to the target position and the display reaches the target position by opening or closing the switch (S341). When the position of the display is not detected by opening or closing the switch in operation S341, the driving motor is operated until the position of the display is detected. As a result, when the display reaches the target position, the driving motor is stopped (S342).

When the re-measured current value of the driving motor and/or the revolution per second of the gear is abnormal, it is determined that the driving motor is still affected by the external force, and thus the driving motor is emergently stopped (S332) and a subsequent operation is performed.
