These drawings and text descriptions are not intended to limit the scope of the present application in any way, but to illustrate the concept of the present application to those skilled in the art by referring to specific embodiments. DETAILED DESCRIPTION

[0046] The following will be combined with the drawings in the embodiments of the present application to clearly and completely describe the technical solutions in the embodiments of the present application. Obviously, the described embodiments are part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application.

[0047] Unless otherwise defined, all technical terms used in the embodiments of the present application have the same meanings as commonly understood by those skilled in the art.

[0048] In order to make the technical solutions and advantages of the present application more clear, the implementation methods of the present application will be further described in detail below with reference to the accompanying drawings.

[0049] Combination Figure 1 As shown, the embodiment of the present application provides a method for controlling power on and off, the method is applied to a vehicle, the vehicle includes a controller, a battery and an ARHUD system, the ARHUD system includes a rotating motor, a curved mirror and an image display unit, the method includes the following steps 101 to 104:

[0050] Step 101: Based on the door lock state, the driver's seat state and the function switch state corresponding to the ARHUD system, the controller generates a first power-on instruction.

[0051] Among them, the first power-on instruction is used to instruct the battery to provide normal power to the rotating motor. Normal power refers to a positive power source connected from the positive pole of the battery and not controlled by any other device such as a switch or relay. It should be noted that the vehicle also includes a door lock system, a driver seat detection system, a battery, a battery power detection system, and a function switch corresponding to the ARHUD system. The door lock system is used to detect the door lock state, wherein the door lock state includes an unlocked state and a locked state, and the door lock system sends the door lock state to the controller. The driver seat detection system is used to detect the driver's seat state and send the seat state to the controller, wherein the driver's seat state includes a seated state and a non-seated state. For example, if the driver detection system detects that the driver's sitting time on the seat reaches the target time, it is determined that the driver is in a seated state, and the target time can be set as needed, which can be 20 seconds, 25 seconds, 30 seconds, etc. The battery power detection system is used to detect the battery power and send the battery power detected to the controller. The function switch corresponding to the ARHUD system is used to respond to the user's opening or closing operation to be in an open state or a closed state, and send the opened state or closed state to the controller. Among them, the function switch can be a software switch or a hardware switch corresponding to the ARHUD system set on the central control screen. For example, the user can choose to turn on or off the function switch by clicking the software switch. It should be noted that when the function switch is in the turned-on state, the rotating motor in the ARHUD system can rotate and the image display unit is allowed to be turned on. The controller is used to receive the door lock system, the driver's seat detection system, the battery power detection system and the door lock state, the driver's seat state, the battery power value and the function switch state sent by the function switch, and generate a first power-on instruction based on the above-mentioned information received. It should be noted that the controller includes a vehicle controller, or the controller includes an audio controller and an upper and lower power controller. When the controller includes an audio controller and an upper and lower power controller, the audio controller is used to receive the state of the software switch corresponding to the ARHUD system sent by the central control screen, and send the switch state to the upper and lower power controller.

[0052] Step 102: In response to the storage battery providing normal power to the rotating motor, the rotating motor controls the curved mirror to rotate from an initial position to a first target position.

[0053] In some embodiments, the initial position is the position of the curved mirror when the ARHUD system is not working. When the curved mirror is in the initial position, it can avoid light exposure, extend the service life of the curved mirror, and thus improve the service life of the ARHUD system. In some embodiments, the first target position can be the position of the curved mirror when the ARHUD system was last in working condition. When the curved mirror is in the first target position, the display effect of various information seen by the driver on the front windshield is optimal.

[0054] Step 103: In response to the battery power being greater than the target power, the controller generates a second power-on instruction.

[0055] The second power-on instruction is used to instruct the battery to provide normal power to the image display unit. The target power refers to the power required by the battery to start the engine. It can be understood that since the image display unit is provided with normal power only when the power of the battery is greater than the target power, it is possible to avoid wasting the power of the battery, thereby avoiding the situation where the engine cannot be started and the vehicle cannot be driven.

[0056] Step 104 : In response to the storage battery providing normal power to the image display unit, the image display unit starts an image display function.

[0057] Among them, turning on the image display function means that the image display unit allows the backlight module in the image display unit to be lit and the imaging module to be turned on when the image display unit is subsequently provided with ON power, so as to display various types of information on the front windshield to assist the driver in driving.

[0058] The power-on and power-off control method provided in the embodiment of the present application, first, the controller generates a first power-on instruction based on the door lock state, the driver's seat state and the function switch state corresponding to the AHUD system, wherein the first power-on instruction is used to instruct the battery to provide normal power to the rotating motor of the ARHUD system, and the rotating motor can control the curved mirror to rotate to the first target position. Since the method can power on the rotating motor based on whether the driver is seated and the driver's needs, it avoids the phenomenon of still providing power to the rotating motor when the driver does not need to use the corresponding function of the ARHUD system, saving power. Then the controller generates a second power-on instruction based on the battery power being greater than the target power, wherein the second power-on instruction is used to instruct the battery to supply power to the image display unit of the ARHUD system. Since the method can determine whether to instruct the power supply unit to supply power to the image display unit based on whether the current battery power is sufficient, it avoids the phenomenon of continuing to supply power when the battery power is insufficient, thereby avoiding the consequence of being unable to start the engine due to wasting battery power, and reasonably utilizing the battery power.

[0059] In order to make the technical solutions and advantages of the present application more clear, the implementation methods of the present application will be further described in detail below with reference to the accompanying drawings.

[0060] Figure 2 This is a flowchart of the power-on process in a power-on and power-off control method provided in an embodiment of the present application, see Figure 2 The power-on process in the power-on and power-off control method includes steps 201 to 207.

[0061] Step 201: Based on the door lock state, the driver's seat state and the function switch state corresponding to the ARHUD system, the controller generates a first power-on instruction.

[0062] Among them, the first power-on instruction is used to instruct the battery to provide normal power to the rotating motor. In some embodiments, in response to the door lock state being unlocked, the driver's seat state being seated, and the function switch state being turned on, the controller generates the first power-on instruction. It can be understood that the door lock state being unlocked means that the driver can enter the car, the driver's seat state being seated means that the driver is sitting in the driving position, and the function switch state is determined based on the driver's operation. When the function switch is turned on, it means that the driver has chosen to turn on the function switch by clicking. By combining the unlocked state, the seated state, and the turned-on state to generate the first power-on instruction, it is possible to more accurately determine and meet the driver's driving needs, more reasonably determine the timing of providing normal power to the motor, avoid wasting battery power, and save power.

[0063] Step 202: In response to the storage battery providing normal power to the rotating motor, the rotating motor controls the curved mirror to rotate from the initial position to the first target position.

[0064] The rotating motor and the curved mirror are connected together, and the curved mirror is used to reflect the image projected by the image display unit onto the front windshield. In some embodiments, the first power-on instruction also carries a target number of revolutions corresponding to the rotating motor, so that when the battery provides normal power to the rotating motor, the rotating motor can rotate a specified number of revolutions based on the target number of revolutions, thereby driving the curved mirror connected to the rotating motor to rotate to the first target position.

[0065] Step 203: In response to the battery power being greater than the target power, the controller generates a second power-on instruction.

[0066] The second power-on instruction is used to instruct the battery to provide normal power to the image display unit.

[0067] In some embodiments, the battery power detection unit is used to detect the battery power and send the detected battery power value to the controller.

[0068] Step 204 : In response to the storage battery providing normal power to the image display unit, the image display unit starts an image display function.

[0069] In some embodiments, after the image display unit turns on the image display function, in response to the battery power being less than or equal to the target power, the controller generates a target power-off instruction and a prompt instruction, wherein the target power-off instruction is used to instruct the battery to disconnect the normal power of the rotating motor and the normal power of the image display unit, and the prompt instruction is used to prompt the user that the information display function of the ARHUD system cannot be used. The prompt instruction can remind the user by voice, for example, the controller sends the prompt instruction to the audio, and the audio broadcasts that the ARHUD system will be powered off within a preset time based on the prompt instruction; or remind the user by text, for example, the controller sends the prompt instruction to the central control screen, and the central control screen generates prompt information based on the prompt instruction. This avoids wasting the battery power before the engine is started and the battery power is insufficient to start the engine, thereby avoiding the phenomenon of being unable to start the engine. That is, by timely disconnecting the normal power of the image display unit and the normal power of the rotating motor, the normal start of the engine can be ensured.

[0070] Step 205: In response to the engine state being the ignition state, the driver's seat state being the seated state, and the function switch state being the turned-on state, the controller generates a third power-on instruction.

[0071] The third power-on instruction is used to instruct the battery to provide ON-speed power to the rotating motor and the image display unit. The ON-speed power refers to the power provided by the battery to all electronic devices in the vehicle when the vehicle is in the ON gear.

[0072] It should be noted that when the rotating motor is provided with ON gear power, the rotating motor can rotate based on the user's adjustment operation. In some embodiments, in response to the engine state being in the ignition state, the controller generates a stop power detection instruction, wherein the stop detection instruction is used to instruct the battery power detection system to stop detecting the battery power. It is understandable that when the engine is ignited and started, the engine is in normal operation, and the vehicle's engine drives the generator to work, and the generator generates electricity and supplies power to the battery, so the battery can remain charged or fully charged, and the battery can continue to supply power to the vehicle's electrical appliances. By generating a stop power detection instruction, it is possible to avoid the battery power detection system from constantly detecting the battery power, saving processing resources.

[0073] Step 206 : In response to the storage battery providing ON power to the rotating motor, the rotating motor controls the curved mirror to remain at the first target position or rotate to the second target position.

[0074] In some embodiments, when the user does not need to adjust the angle of the curved mirror, in response to the battery providing ON gear power to the rotary motor, the rotary motor controls the curved mirror to remain at the first target position.

[0075] In some embodiments, when the user needs to adjust the angle of the curved mirror, the adjustment angle of the curved mirror is determined based on the user's adjustment operation on the central control screen, and the controller generates an adjustment instruction in response to the adjustment operation and sends it to the rotating motor. In response to the battery providing ON gear power to the rotating motor and receiving the adjustment instruction, the rotating motor rotates according to the number of adjustment circles corresponding to the adjustment angle, thereby driving the curved mirror to rotate from the first target position to the second target position.

[0076] Step 207 : In response to the battery providing ON power to the image display unit, the image display unit generates an image and projects the image onto the front windshield.

[0077] In some embodiments, the image display unit generates an image by lighting up the backlight module in the image display unit and turning on the imaging module, so that the image display unit can emit light sources corresponding to various types of information, and project the light sources onto the curved mirror, so that various types of information are displayed on the front windshield after being reflected by the curved mirror. It should be noted that after being emitted, the light source can pass through one or more reflectors to reach the curved mirror, for example, after being emitted, the light source is reflected by a plane mirror to the curved mirror.

[0078] It is understandable that after executing the above steps 201 to 207, the ARHUD system is powered on. At this time, on the windshield, the driver can see various types of information reasonably superimposed and displayed in the field of vision, such as navigation information, driving information, environmental information, etc. The above types of information assist the driver in driving, avoiding the driver from delaying normal driving due to lowering his head to check the dashboard information, thereby improving driving safety. Since this method determines the timing of powering on the rotating motor or the image display unit by combining the door lock status, the driver status, the function switch status, and the battery power, the battery power can be used more reasonably, while meeting user needs, not only saving power, but also improving the user experience.

[0079] Figure 3 This is a flow chart of the power-off process in a power-on and power-off control method provided in an embodiment of the present application. Figure 3 , the power-off process in the power-on and power-off control method provided in the embodiment of the present application is further described in detail. After executing step 207, the power-on and power-off control method further includes the following steps 301 to 307:

[0080] Step 301: Based on the engine status and the driver's seat status, the controller generates a first power-off instruction; or, based on the engine status and the function switch status, the controller generates a first power-off instruction.

[0081] The first power-off instruction is used to instruct the battery to disconnect the ON power of the rotating electric machine and the ON power of the image display unit. The engine state includes an unstarted state, an ignited state, and an off state.

[0082] In some embodiments, based on the engine state and the driver's seat state, the controller generates the first power-off instruction, including: in response to the engine state being an off state and the driver's seat state being an unseated state, the controller generates the first power-off instruction. Thus, by accurately determining that the driver is not in the seat, and then determining that the driver does not need to use the information display function of the ARHUD system at this time, the ON gear power of the rotating motor and the ON gear power of the image display unit can be disconnected in time, which can better save power.

[0083] In some embodiments, based on the engine state and the function switch state, the controller generates a first power-off instruction, including: in response to the engine state being an ignition-off state and the function switch state being an off state, the controller generates a first power-off instruction. Since the state of the function switch is determined based on a click operation of the user, when the function switch state is an off state, it means that the user does not need to use the information display function of the ARHUD at this time, so by timely disconnecting the ON gear power of the rotating motor and the ON gear power of the image display unit, power can be better saved.

[0084] In some embodiments, in response to the engine being in an off state, the controller generates a recovery power detection instruction, where the recovery power detection instruction is used to instruct a power detection system of the battery to detect the power of the battery.

[0085] Step 302: In response to the battery disconnecting the ON power of the rotary motor, the rotary motor controls the curved mirror to maintain the current position.

[0086] It should be noted that the rotating motor cannot rotate after the ON gear power is disconnected, that is, the rotating motor can only remain at the current position and can no longer rotate based on the user's adjustment operation. For example, if the current position of the rotating motor is the first target position, in response to the battery disconnecting the ON gear power of the rotating motor, the rotating motor controls the curved mirror to remain at the first target position; if the current position of the rotating motor is the second target position, in response to the battery disconnecting the ON gear power of the rotating motor, the rotating motor controls the curved mirror to remain at the second target position.

[0087] Step 303: In response to the battery disconnecting the image display unit from the ON position, the image display unit does not generate an image.

[0088] It should be noted that after the image display unit is disconnected from the ON position, the backlight module in the image display single light is in an unlit state, and the imaging module in the image display unit is in a non-imaging state, that is, the image display unit cannot emit an imaging light source at this time.

[0089] It is understandable that after executing step 302 and step 303, since the permanent power of the rotating motor and the permanent power of the image display unit remain connected, when the information display function of the ARHUD system needs to be used next time, it is necessary to re-control the battery to provide ON power to the rotating motor and the image display unit respectively. This can save the steps of the re-powering process, shorten the time for information display on the front windshield again, and improve the efficiency of the information display function of the ARHUD system.

[0090] Step 304: Based on the battery power and the driver's seat status, the controller generates a second power-off instruction, or based on the battery power and the function switch status, the controller generates a second power-off instruction.

[0091] The second power-off instruction is used to instruct the storage battery to disconnect the normal power of the image display unit.

[0092] In some embodiments, in response to the battery power being less than or equal to the target power and the driver's seated state being an unseated state, the controller generates a second power-off instruction. In other embodiments, in response to the battery power being less than or equal to the target power and the function switch being in the off state, the controller generates a second power-off instruction. It is understandable that when the engine is turned off, if the battery power is less than or equal to the target power, it means that the battery cannot start the engine again. Therefore, timely controlling the battery to disconnect the normal power of the image display unit can save power and avoid the situation where the engine cannot be restarted. At the same time, combined with the situation that the driver is not seated or the function switch is in the off state, it can be accurately determined that the driver does not need to use the information display function of the ARHUD system. Therefore, timely disconnecting the normal power of the image display unit can save power while meeting the driver's needs and improving the driver's experience.

[0093] Step 305 : In response to the battery disconnecting the normal power of the image display unit, the image display unit turns off the image display function.

[0094] It should be noted that turning off the image display function refers to turning off the enable signal of the image display unit, and the backlight module and the imaging module of the image display unit after disconnecting the normal power are in a state that they are not allowed to be used.

[0095] Step 306: In response to the door lock state being the locked state, the driver's seat state being the unseated state, and the function switch state being the off state, the controller generates a third power-off instruction.

[0096] The third power-off instruction is used to instruct the battery to disconnect the normal power of the rotating electrical machine.

[0097] It should be noted that before the user gets on the vehicle, the door lock is opened in response to the unlocking operation of the vehicle unlocking device. At this time, the door lock system detects that the door lock state is in the first unlocking state. In response to the first unlocking state, the controller generates a first power-on instruction. When the user gets on the vehicle and drives the vehicle normally for a period of time, the door lock will lock itself. At this time, the door lock system detects that the door lock is in the first locking state. Based on the user operation, the engine is turned off, and the user is ready to get off the vehicle. In response to the unlocking operation of the vehicle unlocking device, the door lock is reopened. At this time, the door lock system detects that the door lock is in the second unlocking state. After the user gets off the vehicle, the door lock is closed in response to the locking operation of the vehicle unlocking device. At this time, the door lock system detects that the door lock state is the second locking state. In response to the second locking state, the driver's seat state is not seated and the function switch state, the controller generates a third power-off instruction. In this way, by combining the door lock state, the driver's unseated state and the function switch state in the off state, it can be more accurately determined that the driver has left the vehicle and does not need to use the information display function of the ARHUD system for a long time, so as to disconnect the normal power of the rotating motor in time to save power.

[0098] Step 307: In response to the battery disconnecting the normal power of the rotating motor, the rotating motor controls the curved mirror to rotate to the initial position.

[0099] By rotating the curved mirror to the initial position, the curved mirror can be prevented from being exposed to light, thereby extending the service life of the curved mirror, thereby improving the service life of the ARHUD system. It should be noted that after executing step 307, the rotating motor or the image display unit can also be powered on based on the power-on process provided in the embodiment of the present application. The power-on and power-off processes can form a cycle.

[0100] The embodiment of the present application uses this power on and off control method, by combining the battery power, the driver's seat status, the status of the function switch, the door lock status and the engine operating status, to provide power to or disconnect the power to the rotating motor and image display unit of the ARHUD system in a more timely manner, thereby not only saving power and preventing waste of battery power, but also improving the use efficiency of the information display function of the ARHUD system and the user experience.

[0101] An embodiment of the present application also provides a vehicle, which includes a door lock system, a driver seat detection system, a battery power detection system, a controller, a battery and an ARHUD system.

[0102] The door lock system is used to detect the door lock status and send the door lock status to the controller, wherein the door lock status includes an unlocked state and a locked state. The driver seat detection system is used to detect the driver seat status and send the seat status to the controller, wherein the driver seat status includes a seated state and a not seated state. The battery power detection system is used to detect the battery power and send the battery power to the controller. The battery is used to supply power to the rotating motor and the image display unit in the ARHUD system. The controller is used to implement the up and down power control method as described in any of the above items. It should be noted that the functions corresponding to the door lock system, the driver seat detection system, the battery power detection system, the controller, the battery and the ARHUD system are the same as the functions in the up and down power control method provided in the above-mentioned embodiment of the present application, and will not be repeated here.

[0103] If it is necessary to explain, the driver's seat detection system can be a seat gravity detection system, which can be provided with a gravity sensor on the seat. When the gravity on the seat exceeds the preset gravity, the driver's seat status is determined to be a seated state. The driver's seat detection system can also be a DMS system, which can determine the driver's seat status through a face recognition device in the DMS system. For example, the face recognition device is a camera component, and the camera component is used to collect face information on the driver's seat. When the camera component continuously collects face information within a preset time, the driver's seat status is determined to be a seated state. Other driver detection systems can also be used to determine the driver's seat status as needed, which will not be elaborated here.

[0104] It should be noted that the controller in the embodiment of the present application may only include the vehicle controller, or the controller may include the vehicle controller, the audio controller and the upper and lower power controller. When the controller includes the vehicle controller, the audio controller and the upper and lower power controller, the audio controller is electrically connected to the central control screen, the door lock system, the hardware switch and the battery are electrically connected to the vehicle controller, the upper and lower power controller is electrically connected to the vehicle controller, the engine controller, the audio controller, the driver's seat detection system and the ARHUD system, and the electrically connected devices can realize signal transmission.

[0105] The vehicle provided in the embodiment of the present application can promptly provide or disconnect power to the image display unit and the rotating motor in the ARHUD system, which can not only save power, but also improve the utilization efficiency of the information display function of the ARHUD system, and can promptly meet user needs, thereby improving the user experience.

[0106] In the present application, the terms "first" and "second" are used for descriptive purposes only and should not be understood as indicating or implying relative importance. The term "plurality" refers to two or more than two, unless otherwise clearly defined.
