Abstract

An on-board head up display (HUD) includes a housing, a support member rotatably connected to the housing, a display screen being transparent and flat, and a side of the display screen is fixed to the support member, and a control device located in the housing and configured to obtain traveling information from an on-board automatic diagnostic system, and the control device is further connected to the display screen and configured to display the traveling information on the display screen, and the control device is connected to the support member and configured to drive the support member to rotate with respect to the housing.

Claims

1. An on-board head up display (HUD), comprising:

a housing;

a support member rotatably connected to the housing;

a display screen being transparent and flat, wherein a side of the display screen is fixed to the support member, such that the display screen is rotatable relative to the housing into any of a range of orientations between an open status and a closed status, the open status corresponding to a front surface of the display screen having a largest intersection angle with an upper surface of the housing, and the closed status corresponding to the front surface of the display screen being in contact with the upper surface of the housing; and

a control device located in the housing and connected to the display screen, and configured to communicatively connect with an on-board automatic diagnostic system, such that;

responsive to the control device not being communicatively connected to the on-board automatic diagnostic system, the control device is configured to automatically drive the support member to rotate the display screen with respect to the housing to the closed status; and

responsive to the control device being communicatively connected to the on-board automatic diagnostic system, the control device is configured to display the traveling information on the display screen and automatically drive the support member to rotate the display screen with respect to the housing to one of the range of orientations other than the closed status.

2. The on-board HUD of claim 1, wherein the display screen is a transparent organic light-emitting display (TOLED) screen.

3. The on-board HUD of claim 1, further comprising a pivot formed on the support member, wherein the pivot is rotatably connected to the housing, and the support member and the display screen are capable of rotating with respect to the housing about an axis of the pivot.

4. The on-board HUD of claim 1, wherein the control device comprises a main control unit (MCU) and a driver motor connected to the MCU, and the driver motor is connected to the support member to drive the support member to rotate.

5. The on-board HUD of claim 1 wherein:

the control device further comprises a rotation rheostat and a voltage detecting device connected to the rotation rheostat;

the rotation rheostat is connected to, and rotates along with, a pivot formed on the support member and rotatably connected to the housing; and

the voltage detecting device detects a voltage applied to both ends of the rotation rheostat and stores a detection result.

6. The on-board HUD of claim 5, wherein:

a first value of the voltage detected by the voltage detecting device corresponds to the closed status;

a second value of the voltage detected by the voltage detecting device corresponds to the open status.

7. The on-board HUD of claim 6, wherein:

responsive to the control device not being communicatively connected to the on-board automatic diagnostic system at a first time, the voltage detecting device is further configured to store a third value of the voltage as the detection result, the third value of the voltage being between the first value and the second value and corresponding to a target position achieved by manual rotation of the display screen to one of the range of orientations prior to the control device automatically driving the support member to rotate the display screen with respect to the housing to the closed status; and

responsive to the control device being communicatively connected to the on-board automatic diagnostic system at a second time subsequent to the first time, the control device is configured to automatically rotate the display screen to the target position in accordance with the stored detection result.

8. The on-board HUD of claim 7, wherein the control device is configured to drive rotation of the display screen so as to stop rotation when the voltage detecting device detects that a voltage applied to both ends of the rotation rheostat is equal to the third value.

9. The on-board HUD of claim 1, wherein the control device comprises a MCU and a tire pressure detecting and receiving unit (TPDRU), the TPDRU comprises a main board and a wireless data transmission card integrated on the main board, the wireless data transmission card is in wireless connection with a tire pressure sensor mounted on a tire, and both of the main board and the display screen are connected to the MCU.

10. The on-board HUD of claim 9, wherein the tire pressure detecting and receiving device is removably connected to the MCU, the housing defines a receiving slot configured to receive the tire pressure detecting and receiving device.

11. The on-board HUD of claim 1, wherein the control device is in wireless connection with the on-board automatic diagnostic system.

12. The on-board HUD of claim 1, wherein the on-board automatic diagnostic system has an output interface, the control device is connected to the output interface through a data transmission cable.

13. The on-board HUD of claim 1, wherein:

there are a plurality of pieces of the traveling information; and

the control device is configured to display the traveling information on the display screen in a form of a plurality of information blocks, wherein each information block corresponds to one of the plurality of pieces of the traveling information.

14. The on-board HUD of claim 13 wherein the display screen is divided into a plurality of display regions, each display region for display of at least one of the information blocks, and displaying colors of two adjacent display regions are different.

15. The on-board HUD of claim 1, wherein:

there are a plurality of pieces of the traveling information; and

the control device is configured to display the traveling information on the display screen in a form of a plurality of information blocks, wherein each information block corresponds to a combination of the plurality of pieces of the traveling information.

16. The on-board HUD of claim 15, wherein the display screen is divided into a plurality of display regions, each display region for display of at least one of the information blocks, and displaying colors of two adjacent display regions are different.

17. The on-board HUD of claim 1, wherein, responsive to the control device being communicatively connected to the on-board automatic diagnostic system, the control device is automatically to rotate the display screen to the open status.

18. The on-board HUD of claim 1, wherein:

responsive to the control device not being communicatively connected to the on-board automatic diagnostic system at a first time, the control device is further configured to record a target positionachieved by manual rotation of the display screen to one of the range of orientations prior to the control device automatically driving the support member to rotate the display screen with respect to the housing to the closed status; and

responsive to the control device being communicatively connected to the on-board automatic diagnostic system at a second time subsequent to the first time, the control device is configured to automatically rotate the display screen to the target position.
