Description

Technical Field

[0001] The present invention relates to the technical field of head-up display, and in particular to a head-up display memory system and method. Background Art

[0002] Head Up Display (HUD), also known as Head Up Display System or HUD. The three main types of HUD currently used in the market are C-HUD, W-HUD and AR-HUD. Among them, W-HUD (windshield HUD) and AR-HUD (Augmented Reality HUD) both use the front windshield of the car as the imaging medium, and use the windshield as the projection medium to reflect the image, thereby forming a virtual image visible to the naked eye.

[0003] At present, the display image of the head-up display on the market can only be seen in a specific area of ​​the human eye. If it exceeds this area, the image cannot be seen. Figure 1 As shown, the height of the HUD display must be manually adjusted every time to fully see the image. The image area visible to the human eye is very sensitive to the seat height, body height and glasses position. The image cannot be seen beyond this area. Even the same driver needs to manually adjust the height of the HUD when using different seat positions, which brings great inconvenience to the user. The usual head-up display system cannot store multiple positions according to actual conditions, nor can it be automatically called according to different heights and sitting postures, and its versatility and convenience are poor.

[0004] Moreover, HUD usually does not support self-diagnosis of its own faults, image adjustment and motor adjustment, and cannot reflect the functional status of the head-up display. Most of those with diagnostic functions also need to transmit and analyze diagnostic data through the CAN bus, and then use special equipment (such as instruments) to display the diagnostic results. The solution is relatively complex and costly, resulting in high costs for HUD image display and motor adjustment self-diagnosis. Summary of the invention

The position memory button 5 is respectively connected to the HUD position storage unit 21 and the seat position storage unit 12 for storing or retrieving the seat position information and / or the HUD position information.

[0046] When in use, the driver adjusts the seat position through the seat adjustment button 3, adjusts the HUD position through the HUD adjustment button 4, and stores the seat position information and the HUD position information in a corresponding manner through the position memory button 5. After the driver gets on the vehicle, he first calls up the seat position information through the position memory button 5, and at the same time calls up the matching HUD position information. The seat control unit 11 adjusts the seat position based on the seat position information, and the HUD control unit 22 adjusts the HUD position based on the HUD position information, thereby achieving one-touch adjustment of the seat and HUD, so that the positions of the seat and HUD match the driver at the same time.

[0047] The HUD position information and the seat position information can be collected by sensors and transmitted to the HUD position storage unit 21 and the seat position storage unit 12 respectively. The HUD position storage unit 21 can also be connected to the HUD adjustment button 4 to indirectly record the HUD position information based on the rotation and other movements of the HUD adjustment button 4. Similarly, the seat position storage unit 12 can be connected to the seat adjustment button 3 to indirectly record the seat position information based on the rotation and other movements of the seat adjustment button 3. The seat adjustment button 3 is connected to the seat controller 1 through a hard line.

[0048] The seat position storage unit 12 includes a seat default position storage area 120 and a plurality of seat position storage areas. The seat default position storage area 120 is used to store seat position information that does not match the HUD position information, and the seat position storage area is used to store seat position information that matches the HUD position information. The HUD position storage unit 21 includes a HUD default position storage area 210 and a plurality of HUD position storage areas. The HUD default position storage area 210 is used to store HUD position information that does not match the seat position information, and the HUD position storage area is used to store HUD position information that matches the seat position information. The position memory button 5 includes a storage button 50 and a position button. The storage button 50 is used to store the seat position information and / or the HUD position information in the corresponding storage area. There are a plurality of position buttons, which are respectively connected to the seat position storage area and the HUD position storage area.

[0049] like Figure 3 As shown, the seat position storage unit 12 of an embodiment of the present invention has three seat position storage areas, namely, the first seat position storage area 121, the second seat position storage area 122, and the third seat position storage area 123; the HUD position storage unit 21 has three HUD position storage areas, namely, the first HUD position storage area 211, the second HUD position storage area 212, and the third HUD position storage area 213. The seat position information of the first seat position storage area 121 matches the HUD position information of the first HUD position storage area 211, the seat position information of the second seat position storage area 122 matches the HUD position information of the second HUD position storage area 212, and the seat position information of the third seat position storage area 123 matches the HUD position information of the third HUD position storage area 213. The position memory button 5 is provided with three position buttons, namely, the first position button 51, the second position button 52, and the third position button 53. The first position button 51 corresponds to storing or retrieving the seat position information of the first seat position storage area 121 and the HUD position information of the first HUD position storage area 211, the second position button 52 corresponds to storing or retrieving the seat position information of the second seat position storage area 122 and the HUD position information of the second HUD position storage area 212, and the third position button 53 corresponds to storing or retrieving the seat position information of the third seat position storage area 123 and the HUD position information of the third HUD position storage area 213.

[0050] In one embodiment of the present invention, the HUD control unit 22 drives the position adjustment of the HUD by controlling the HUD motor, and the seat control unit 11 drives the position adjustment of the seat by controlling the seat motor. Specifically, when the HUD adjustment button 4 is turned on and off, the head-up display will respond to the corresponding button and turn on and off accordingly. When the head-up display is turned on, the user can adjust the height and / or angle of the image display by adjusting the HUD adjustment button 4, so that people of different heights can see the corresponding output image. When storing the position, press the storage button 50 to activate the memory mode, and the corresponding HUD position storage unit 21 and the seat position storage unit 12 will enter the memory mode in response to the button operation; thereafter, the HUD position storage unit 21 and the seat position storage unit 12 respond to one of the position buttons (for example, the first position button 51), identify and store the current HUD position (image and HUD motor position) and the seat position (or seat motor position) in the corresponding HUD position storage area (for example, the first HUD position storage area 211) and the seat position storage area (for example, the first seat position storage area 121), so as to realize the corresponding storage of the HUD position information and the seat position information. When calling a position, directly pressing a position button (for example, the first position button 51) will activate the position calling mode. The HUD controller 2 and the seat controller 1 enter the position calling mode in response to the button operation, and respectively retrieve the corresponding HUD position information (image and HUD motor position) and the seat position (or seat motor position) from the corresponding HUD position storage area (for example, the first HUD position storage area 211) and the seat position storage area (for example, the first seat position storage area 121); thereafter, the HUD control unit 22 and the seat control unit 11 respectively output motor drive signals to drive the HUD motor and the seat motor to run to the corresponding positions, thereby driving the HUD and the seat to be adjusted to the specified positions.

[0051] In one embodiment of the present invention, the HUD controller 2 and the seat controller 1 are connected via CAN communication to transmit HUD position information and seat position information to each other. When the HUD position is stored, the storage button 50 is pressed to trigger the signal, and the seat controller 1 can transmit the seat position storage area of ​​the seat position information to the HUD controller 2. After receiving the signal, the HUD controller 2 will store the current HUD position information to the corresponding internal HUD position storage area, and return a confirmation signal after the storage is successful. When the HUD position is retrieved, the corresponding position button is pressed to trigger the seat controller 1, and the seat position storage unit 12 transmits the seat position storage area of ​​the seat position information to the HUD controller 2. After receiving the signal, the HUD controller 2 confirms that the HUD adjustment button 4 is turned on, and retrieves the HUD position information from the corresponding HUD position storage area, and drives the HUD motor to adjust the HUD image to the corresponding height and / or angle.

[0052] The position memory button 5 (including the storage button 50 and all the position buttons) of an embodiment of the present invention is respectively connected to the HUD controller 2 and the seat controller 1 through hard wires. Hard wire refers to a type of wire, which means that the metal core wire of the wire is solid, the outside is covered with insulating material, the diameter is usually large, and it has good conductivity and mechanical strength.

[0053] In order to reduce costs and quickly perform fault detection, the HUD controller 2 also includes a self-diagnosis unit 23, which enters the self-diagnosis mode by long pressing the operation to perform self-diagnosis of internal faults. The self-diagnosis unit 23 is used to detect whether there are faults in the HUD motor, PGU, and the input signal of the HUD controller 2. PGU stands for the image generation unit (Power Generation Unit or Image Generation Unit), which is one of the core components in the HUD, responsible for generating graphics and controlling brightness, and directly affects the core performance such as imaging quality, hardware volume, and power consumption. The input signal of the HUD controller 2 refers to the HUD position information, external command signals, etc. The self-diagnosis unit 23 can be connected to the ON / OFF button, and the self-diagnosis mode can be entered by pressing the button.

[0054] The head-up display memory system of an embodiment of the present invention further includes a signal light 6 (LED), which is connected to the HUD controller 2 and the position memory button 5. The signal light 6 indicates the HUD switch state, the position storage mode, the position retrieval mode and / or the self-diagnosis result of the HUD controller 2 through different flashing modes, and flashes in a preset flashing mode to prompt the user that a fault has occurred and can be quickly diagnosed and eliminated. Different faults can be displayed according to different faults.

[0055] The signal light 6 includes a normally-on mode indicating that the HUD is in the on state (i.e., when the HUD is on, the LED is activated and displayed), a normally-off mode indicating that the HUD is in the off state (i.e., when the HUD is off, the LED is off and displayed), a first flashing mode indicating that it is in the position storage mode, a second flashing mode indicating that it is in the position retrieval mode, a third flashing mode indicating that all self-diagnosis results of the HUD controller 2 are normal, a fourth flashing mode indicating a HUD motor failure, a fifth flashing mode indicating a PGU failure (such as PGU overheating), and a sixth flashing mode indicating a HUD controller 2 input signal failure (such as missing HUD controller 2 input signal).

[0056] Specifically, when the storage button 50 is pressed to trigger the position storage mode, the signal light 6 is in the first flashing mode. After the position storage is completed, the signal light 6 returns to the constant light mode indicating the HUD is on or the constant close mode indicating the HUD is off. In the position storage mode, if the storage button 50 is pressed but the corresponding position button is not pressed before the timeout, that is, the position storage is not completed, the signal light 6 will end the first flashing mode in about 10 seconds.

[0057] When the position is retrieved, the position button is pressed to trigger the position retrieval mode, and the signal light 6 is in the second flashing mode. After the HUD is adjusted to the specified position and the position retrieval is completed, the signal light 6 returns to the normally lit mode indicating the HUD is on or the normally closed mode indicating the HUD is off. In the position retrieval mode, if the position button is pressed but a fault occurs or the position retrieval is not completed due to timeout, the signal light 6 will end the first flashing mode in about 10 seconds, enter the self-diagnosis mode for diagnosis, and then switch to the corresponding fault flashing mode.

[0058] If the self-diagnosis mode is entered, if all functions are normal, the signal light 6 will be in the third flashing mode to indicate that the functions are normal; if a function fails, the signal light 6 will be in the corresponding flashing mode, such as if the HUD motor fails, the signal light 6 will be in the fourth flashing mode. If the self-diagnosis mode is exited, the signal light 6 will return to the constant light mode indicating that the HUD is turned on.

[0059] The first flashing mode of an embodiment of the present invention is to light up for half a second and then darken for half a second, that is, one flashing cycle is 1 second, see Figure 4 The second flashing mode is one second on and one second off, that is, one flashing cycle is 2 seconds, see Figure 5 The third flashing mode is four seconds of light and one second of dark, that is, one flashing cycle is 5 seconds, see Figure 6 The fourth flashing mode is three seconds of light and one second of dark, that is, one flashing cycle is 4 seconds, see Figure 7 The fifth flashing mode is two seconds of light and one second of dark, that is, one flashing cycle is 3 seconds, see Figure 8 The sixth flashing mode is one second on and two seconds off, that is, one flashing cycle is 3 seconds, see Fig. 9 Among them, flashing means brightening once and dimming once.

[0060] The signal light 6 of one embodiment of the present invention is connected to the HUD controller 2 via a hard wire.

[0061] The present invention also proposes a head-up display memory method, which is applied to the head-up display memory system as described above, and comprises the following steps:

[0062] Adjust HUD position and / or seat position;

[0063] storing the HUD position information and the seat position information in correspondence with each other;

[0064] When retrieving the seat position information, the corresponding HUD position information is also retrieved;

[0065] The seat and HUD are adjusted to the set position according to the seat position information and the corresponding HUD position information.

[0066] When the seat position information is missing and the HUD position information has no corresponding matching seat position information, it can be stored in the initial default position.

[0067] It should be noted that, in this application, unless otherwise clearly specified and limited, "connection" and other similar terms should be understood in a broad sense. For example, "connection" can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection, an indirect connection through an intermediate medium, or the internal connection of two components. Those skilled in the art can understand the specific meanings of the above terms in this application according to the specific circumstances. In addition, the terms "first", "second", "third", "fourth", "fifth", and "sixth" are used only for descriptive purposes and cannot be understood as indicating or implying relative importance.
