Unless defined otherwise, all technical terms used in the examples of the present application have the same meaning as commonly understood by one of ordinary skill in the art.
In order to make the technical solutions and advantages of the present application clearer, the following will describe the embodiments of the present application in further detail with reference to the accompanying drawings.
As shown in fig. 1, an embodiment of the present application provides a power-on and power-off control method, which is applied to a vehicle, where 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, and the method includes the following steps 101 to 104:
The first power-on command is used for instructing the storage battery to provide constant power for the rotating electric machine. The normal electricity refers to a positive power supply which is connected from the positive electrode of the storage battery and is not controlled by any switch, relay or other equipment. The vehicle further includes a door lock system, a driver seating detection system, a battery charge detection system, and function switches corresponding to the ARHUD system. The door lock system is used for detecting a door lock state, wherein the door lock state comprises an unlocked state and a locked state, and the door lock system sends the door lock state to the controller. The driver seating detection system is used for detecting and detecting a seating state of a driver and sending the seating state to the controller, wherein the seating state of the driver comprises a seated state and an unseated state. For example, when the driver detection system detects that the duration of the driver sitting on the seat reaches the target time, the driver is determined to be in the seated state, and the target time may be set as needed, and may be 20 seconds, 25 seconds, 30 seconds, or the like. The electric quantity detection system of the storage battery is used for detecting the electric quantity of the storage battery and sending the detected electric quantity of the storage battery to the controller. The function switch corresponding to the ARHUD system is used for responding to the opening operation or the closing operation of a user to be in an opened state or a closed state and sending the opened state or the closed state to the controller. The function switch can be a software switch or a hardware switch corresponding to the ARHUD system arranged on the central control screen. For example, the user may select to turn the function switch on or off by clicking on the software switch. It should be noted that when the function switch is in the turned-on state, the rotation motor in the ARHUD system can rotate, and the image display unit is allowed to be turned on. The controller is used for receiving the door lock state, the driver sitting state, the electric quantity value of the storage battery and the function switch state sent by the door lock system, the driver sitting detection system, the electric quantity detection system of the storage battery and the function switch, and generating a first power-on command based on the received information. It should be noted that the controller includes a vehicle control unit, or the controller includes an audio controller and a power-on/power-off controller. When the controller comprises the sound controller and the power-on and power-off controller, the sound controller is used for receiving the state of the software switch corresponding to the ARHUD system and sent by the central control screen, and sending the switch state to the power-on and power-off controller.
And 102, responding to the storage battery to provide constant power for the rotating motor, and controlling the curved mirror to rotate from the initial position to the first target position by the rotating motor.
In some embodiments, the initial position is the curved mirror position when the ARHUD system is not operating, when the curved mirror is in the initial position, illumination can be avoided, the service life of the curved mirror is prolonged, and therefore the service life of the ARHUD system can be prolonged. In some embodiments, the first target position may be a position of the curved mirror when the ARHUD system was last in operation, and when the curved mirror is in the first target position, the display effect of various types of information seen by the driver on the front windshield is optimal.
And 103, responding to the fact that the electric quantity of the storage battery is larger than the target electric quantity, and generating a second power-on instruction by the controller.
And the second power-on instruction is used for instructing the storage battery to provide constant power for the image display unit. The target electric quantity refers to an electric quantity required for the battery to start the engine. When can understand, because when the electric quantity of battery is greater than the target electric quantity, just provide the normal electricity to the image display element, consequently can avoid extravagant battery's electric quantity, and then avoid appearing the unable condition of going of vehicle that causes of unable engine start.
And step 104, responding to the storage battery to provide normal power for the image display unit, and starting the image display function by the image display unit.
The image display unit is started to allow the backlight module in the image display unit to be lightened and the imaging module to be opened after the image display unit is subsequently provided with ON gear electricity, so that various information is displayed ON the front windshield to assist the driving of a driver.
According to the power-on and power-off control method provided by the embodiment of the application, firstly, the controller generates a first power-on command based on a door lock state, a driver sitting state and a function switch state corresponding to the AHUD system, wherein the first power-on command is used for indicating the storage battery to provide normal power for the rotating motor of the ARHUD system, and at the moment, the rotating motor can control the curved mirror to rotate to a first target position. Because the method can be used for electrifying the rotating motor based on whether the driver sits or not and the requirement of the driver, the phenomenon that the power supply is still provided for the rotating motor under the condition that the driver does not need to use the corresponding function of the ARHUD system is avoided, and the electric quantity is saved. And then the controller generates a second power-on instruction based on the fact that the electric quantity of the storage battery is larger than the target electric quantity, wherein the second power-on instruction is used for indicating the storage battery to supply power to an image display unit of the ARHUD system. The method can determine whether to instruct the power supply unit to supply power to the image display unit or not based on whether the current electric quantity of the storage battery is sufficient or not, so that the phenomenon that power is continuously supplied when the electric quantity of the storage battery is insufficient is avoided, the consequence that the engine cannot be started due to the waste of the electric quantity of the storage battery is further avoided, and the electric quantity of the storage battery is reasonably utilized.
In order to make the technical solutions and advantages of the present application clearer, the following will describe the embodiments of the present application in further detail with reference to the accompanying drawings.
Fig. 2 is a flowchart of a power-on process in a power-on and power-off control method provided in an embodiment of the present application, and referring to fig. 2, the power-on process in the power-on and power-off control method includes steps 201 to 207.
The first power-on command is used for instructing the storage battery to provide constant power for the rotating electric machine. In some embodiments, the controller generates the first power-on command in response to the door lock state being the unlocked state, the driver seated state being the seated state, and the function switch state being the open state. It is understood that the state of the door lock being the unlocked state represents that the driver can enter the vehicle, the seated state represents that the driver is seated at the driving position, and the state of the function switch is determined based on the operation of the driver, and when the state of the function switch being the open state represents that the driver selects the open function switch by a click operation. The method for generating the first power-on command by combining the unlocked state, the seated state and the opened state can more accurately determine and meet the driving requirement of a driver, more reasonably determine the time for providing normal power for the motor, avoid the waste of the electric quantity of the storage battery and save the electric quantity.
The rotary motor is connected with the curved mirror, and the curved mirror is used for reflecting the image projected by the image display unit to the front windshield. In some embodiments, the first power-on command further carries a target number of revolutions corresponding to the rotating electrical machine, so that when the storage battery provides a normal power to the rotating electrical machine, the rotating electrical machine can rotate for a specified number of revolutions based on the target number of revolutions, and then the curved mirror connected to the rotating electrical machine is driven to rotate to the first target position.
And step 203, responding to the electric quantity of the storage battery larger than the target electric quantity, and generating a second power-on instruction by the controller.
And the second power-on instruction is used for instructing the storage battery to provide constant power for the image display unit.
In some embodiments, the charge detection unit of the storage battery is configured to detect the charge of the storage battery and send the detected charge value of the storage battery to the controller.
And step 204, responding to the storage battery to provide normal power for the image display unit, and starting the image display function by the image display unit.
In some embodiments, after the image display unit starts the image display function, the controller generates a target power-down instruction and a prompt instruction in response to the battery power being less than or equal to the target power, wherein the target power-down instruction is used for instructing the battery to disconnect the normal power of the rotating electrical machine and the normal power of the image display unit, and the prompt instruction is used for prompting a user that the information display function of the ARHUD system is unavailable. The prompting instruction can remind a user in a voice mode, for example, the controller sends the prompting instruction to the sound box, and the sound box broadcasts that the ARHUD system is powered off within preset time based on the prompting instruction; or the user is reminded in a text mode, for example, the controller sends a prompt instruction to the central control screen, and the central control screen generates prompt information based on the prompt instruction. Therefore, the electric quantity of the storage battery is avoided being wasted before the engine is not started and under the condition that the electric quantity of the storage battery is not enough to start the engine, and the phenomenon that the engine cannot be started is avoided. That is, by timely disconnecting the normal power of the image display unit and the normal power of the rotating electric machine, the normal start of the engine can be ensured.
And the third power-ON instruction is used for instructing the storage battery to provide ON gear power for the rotating motor and the image display unit. The ON gear power is the power provided by the storage battery to all electronic devices in the vehicle when the vehicle is in the ON gear.
It should be noted that, when the rotating electric machine is supplied with the ON gear, the rotating electric machine may be rotated based ON the adjustment operation by the user. In some embodiments, the controller generates a stop detection charge command in response to the engine state being an ignited state, wherein the stop detection command is to instruct a charge detection system of the battery to stop detecting the charge of the battery. It can be understood that, when the engine is started by ignition and the engine is in normal operation, the engine of the vehicle drives the generator to operate, the generator generates electricity and supplies power to the storage battery, so that the storage battery can be kept in a charged or full-charged state, and the storage battery can continuously supply power to the electrical appliances of the vehicle. By generating the instruction of stopping detecting the electric quantity, the electric quantity detection system of the storage battery can be prevented from directly detecting the electric quantity of the storage battery, and processing resources are saved.
In some embodiments, the rotary motor controls the curved mirror to remain in the first target position in response to the battery providing ON power to the rotary motor when the user does not need to adjust the angle of the curved mirror.
In some embodiments, when a user needs to adjust the angle of the curved mirror, the adjustment angle of the curved mirror is determined based on an adjustment operation of the user on the central control screen, and the controller generates an adjustment instruction in response to the adjustment operation and sends the adjustment instruction to the rotating motor. The rotating motor responds to the storage battery to provide ON gear power for the rotating motor and receives an adjusting instruction, and the rotating motor rotates according to the adjusting turns corresponding to the adjusting angle, so that the curved mirror is driven to rotate from the first target position to the second target position.
And step 207, responding to the storage battery to provide the ON gear power for the image display unit, and the image display unit generates an image and projects the image onto the front windshield.
In some embodiments, the image display unit generates the image by lighting a backlight module in the image display unit and turning on an 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, and various types of information are displayed on the front windshield after being reflected by the curved mirror. It should be noted that the light source may be emitted and then reflected onto the curved mirror via one or more mirrors, for example, the light source may be emitted and then reflected onto the curved mirror via a flat mirror.
It can be understood that, after the steps 201 to 207 are performed, the ARHUD system is powered on, and at this time, on the windshield, the driver can see various information reasonably displayed in a superimposed manner, such as navigation information, driving information, environmental information and the like, in the sight area, and the driving of the driver is assisted by the various information, so that the driver is prevented from delaying normal driving due to looking down at instrument panel information, and the driving safety can be improved. According to the method, the door lock state, the driver state, the function switch body and the electric quantity of the storage battery are combined, and the time for electrifying the rotating motor or the image display unit is determined, so that the electric quantity of the storage battery can be used more reasonably, the user requirements can be met, the electric quantity is saved, and the user experience is improved.
Fig. 3 is a flowchart of a power-down process in a power-down control method according to an embodiment of the present disclosure. Next, referring to fig. 3, a power-down process in the power-up and power-down control method provided in the embodiment of the present application is further described in detail. After step 207 is executed, the power-on and power-off control method further includes the following steps 301 to 307:
301, based on the engine state and the driver sitting state, generating a first power-down instruction by a controller; alternatively, the controller generates a first power-down command based on the engine state and the function switch state.
Wherein the first power-down instruction is for instructing the battery to disconnect an ON-gear of the rotating electrical machine and an ON-gear of the image display unit. The engine states include an un-started state, an ignited state, and a flameout state.
In some embodiments, the controller generating the first downlink command based on the engine state and the driver seated state comprises: the controller generates a first power-down command in response to the engine state being a key-off state and the driver seated state being an unseated state. Therefore, the driver can be accurately judged not to be in the seat, the information display function of the ARHUD system is not needed to be used by the driver at the moment, the ON gear of the rotating motor and the ON gear of the image display unit are timely disconnected, and the electric quantity can be better saved.
In some embodiments, the controller generating the first power down command based on the engine state and the functional switch state comprises: the controller generates a first power-down command in response to the engine state being a shutdown state and the function switch state being an off state. Since the state of the function switch is determined based ON the click operation of the user, when the state of the function switch is the off state, the representative user does not need to use the information display function of the ARHUD at this time, and therefore, the electric power can be saved better by disconnecting the ON-gear of the rotary electric machine and the ON-gear of the image display unit in time.
In some embodiments, in response to the engine state being a shutdown state, the controller generates a recovery power detection instruction for instructing a power detection system of the battery to detect a power of the battery.
In response to the battery de-energizing the rotary motor, the rotary motor controls the curved mirror to remain in the current position, step 302.
It should be noted that the rotating electrical machine cannot be rotated after the ON gear is turned off, that is, the rotating electrical machine can only be kept at the current position and cannot be rotated any more based ON the adjustment operation of the user. For example, if the current position of the rotating electrical machine is the first target position, the rotating electrical machine controls the curved mirror to maintain the first target position in response to the battery disconnecting the ON gear of the rotating electrical machine; and if the current position of the rotating motor is the second target position, the rotating motor controls the curved mirror to be kept at the second target position in response to the fact that the storage battery cuts off the ON gear of the rotating motor.
It should be noted that, after the image display unit is powered off from the ON state, the backlight module in the single image display light is in the unlit state, and the imaging module in the image display unit is in the non-imaging state, that is, the image display unit cannot emit the imaging light source at this time.
It is understood that after steps 302 and 303 are performed, since the normal power of the rotating electrical machine and the normal power of the image display unit are still kept in the ON state, it is necessary to use the information display function of the ARHUD system next time, that is, to newly control the storage battery to supply the ON-range power to the rotating electrical machine and the image display unit, respectively. Therefore, the step of the power-on process can be saved, the time for displaying the information on the front windshield again is prolonged, and the use efficiency of the information display function of the ARHUD system is improved.
And step 304, based on the electric quantity of the storage battery and the driver sitting state, the controller generates a second power-off command, or based on the electric quantity of the storage battery and the functional switch state, the controller generates the second power-off command.
Wherein the second power-off command is used for instructing the storage battery to disconnect the normal power of the image display unit.
In some embodiments, the controller generates a second power-down command in response to the charge of the battery being less than or equal to the target charge and the driver's seated state being an unseated state. In other embodiments, the controller generates the second power-down command in response to the charge of the battery being less than or equal to the target charge and the functional switch being in the off state. It can be understood that, after the engine is shut down, if the electric quantity of the storage battery is less than or equal to the target electric quantity, the storage battery cannot restart the engine, so that the storage battery is timely controlled to be powered off from the normal power of the image display unit, the electric quantity can be saved, and the situation that the engine cannot be restarted is avoided. Meanwhile, the driver can be accurately judged to be in a state of not sitting or the function switch is in a closed state without using the ARHUD system, so that the normal power of the image display unit is timely disconnected, the requirement of the driver can be met while the electric quantity is saved, and the experience of the driver is improved.
It should be noted that turning off the image display function means turning off the enable signal of the image display unit, and the backlight module and the imaging module of the image display unit after the normal power is turned off are in a state of not allowing to be used.
And step 306, responding to the condition that the door lock state is a locking state, the driver sitting state is a non-sitting state and the function switch state is a closing state, and generating a third power-off command by the controller.
Wherein the third power-off command is used for instructing the storage battery to disconnect the normal power of the rotating electric machine.
It should be noted that, when a user gets in front of the vehicle, the door lock is opened in response to an unlocking operation of the vehicle unlocking device, and at this time, the door lock system detects that the door lock state is in the first unlocking state, and in response to the first unlocking state, the controller generates a first power-on instruction. After a user gets on the vehicle and drives the vehicle to normally run for a period of time, the door lock can be locked by self, and the door lock system detects that the door lock is in a first locking state. Based on the user operation, the engine is shut down, the user prepares to get off the vehicle, the door lock is reopened in response to the unlocking operation of the vehicle unlocking device, and the door lock system detects that the door lock is in the second unlocking state.
