For the purpose of explanation rather than limitation, specific details such as specific system structures and technologies are provided to facilitate a thorough understanding of the embodiments of the present application. However, it should be clear to those skilled in the art that the present application can also be implemented in other embodiments without these specific details.
[0030] The phrases such as "one embodiment" or "some embodiments" described in the present application mean that the specific features, structures or characteristics described in the embodiment are included in one or more embodiments of the present application. Therefore, the phrases such as "in one embodiment", "in some embodiments", "in some other embodiments", "in some other embodiments" etc. that appear in different places in the present application do not necessarily refer to the same embodiment, but mean "one or more but not all embodiments", unless otherwise specifically emphasized in other ways.
[0031] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.
[0032] See also Figure 1 The figure is a flow chart of a method for controlling a vehicle door and an electronic rearview mirror in linkage with each other in a specific embodiment. As an implementation method of this embodiment, the following steps are included: S101: receiving an exterior door opening control signal sent by a remote control key.
[0033] In some embodiments, the remote control key is provided with a door opening button, and when the owner presses the button, the remote control key will emit a wireless signal. The vehicle controller or door controller of the vehicle will capture the wireless signal sent by the remote control key and decode it into an external door opening control signal.
[0034] This embodiment then sends this control signal to the vehicle controller or door controller for processing.
[0035] S102: The door controller sends an exterior door opening control signal to the electronic rearview mirror.
[0036] In some embodiments, after receiving the door opening control signal from outside the vehicle, the door controller will perform signal verification and processing. After the verification is passed, the door controller will send the control signal to the electronic rearview mirror through the CAN bus inside the vehicle.
[0037] The electronic rearview mirror of this embodiment is equipped with a control unit, which can control the operation of the display unit of the electronic rearview mirror according to a control signal.
[0038] Specifically, after receiving the signal, the control unit of the electronic rearview mirror is ready to control the display unit to perform the display operation. The linkage between the door switch lock control and the electronic rearview mirror is realized, which enhances the integrity and intelligence of the vehicle system. The reliability and real-time performance of signal transmission are improved, ensuring that the electronic rearview mirror can respond in time.
[0039] S103: The electronic rearview mirror responds to the door opening control signal outside the vehicle and opens after a preset time period to display video information of the left, right and rear sides of the vehicle.
[0040] In some embodiments, after receiving the door opening control signal, the control unit of the electronic rearview mirror starts an internal timer. When the timer reaches a preset time, which can be 2 to 5 seconds or longer, to ensure that the door is fully opened and the driver is ready to view the video information, the control unit activates the camera and display unit of the electronic rearview mirror. The camera starts to capture video information from the left and right sides and rear of the vehicle, and transmits the video information to the display unit of the electronic rearview mirror in real time for display. It helps the driver to better understand the surrounding environment before opening the door and improves driving safety. It reduces the visual blind spot, allowing the driver to more easily grasp the situation around the vehicle.
[0041] The vehicle door control and electronic rearview mirror linkage control method provided in the embodiment of the present application also involves the door opening process and the electronic rearview mirror linkage control.
[0042] The specific steps include: Figure 2 As shown: S201: Receive a door opening control signal from inside the vehicle.
[0043] In some embodiments, door control switches or buttons are usually provided near the doors inside the vehicle. When the driver or passenger presses these switches or buttons, an electrical signal to open or close the door is triggered. The electrical signal is then transmitted to the door controller through the vehicle's electrical system. The door controller is a key component inside the vehicle and is responsible for processing various signals and control instructions related to the door.
[0044] The door controller of this embodiment may include a left door controller and a right door controller. After receiving the door opening control signal in the vehicle, the door controller performs preliminary verification and processing to ensure the legitimacy and accuracy of the signal.
[0045] S202: The door controller sends an interior door opening control signal to the electronic rearview mirror.
[0046] In this embodiment, after verifying and processing the in-vehicle door opening control signal, the door controller will send it to the control unit of the electronic rearview mirror through the vehicle CAN bus.
[0047] The CAN bus in this embodiment is a channel for transmitting data and information between various systems inside the vehicle, ensuring efficient and accurate data transmission. After receiving the door opening control signal inside the vehicle, the control unit of the electronic rearview mirror will process and prepare to respond to the door opening control signal. The linkage between the door control and the electronic rearview mirror is realized, and the integrity and intelligence level of the vehicle system are improved. It can also enhance the collaborative working ability between various systems inside the vehicle.
[0048] S203: The electronic rearview mirror responds to the door opening control signal from inside the vehicle and turns on after a preset time period to display video information of the left, right and rear sides of the vehicle.
[0049] After receiving the door opening control signal from the vehicle, the control unit of the electronic rearview mirror of this embodiment starts the internal timer. After the timer reaches the preset time, the control unit activates the camera and video display function of the electronic rearview mirror. The preset time can be 2 seconds to 5 seconds or longer.
[0050] The camera of the electronic rearview mirror of this embodiment starts to capture video information of the left and right sides and rear of the vehicle, and transmits the information to the display unit of the electronic rearview mirror in real time for display. In this way, the driver or passenger can clearly see the environment around the vehicle before opening the door. The risk of traffic accidents caused by obstructed vision is reduced. The safety awareness and vigilance of the driver or passenger before opening the door are enhanced, and driving safety is improved.
[0051] As for this embodiment, the following several methods of linkage control between vehicle door control and electronic rearview mirror are also involved.
[0052] During the linkage process of the main driver's seat scene, the signal is sent at the main driver's seat. When the driver presses the one-touch wake-up button on the left door switch, the left door switch will immediately generate a one-touch wake-up signal.
[0053] The one-button wake-up signal is then sent to the left door controller. As a communication bridge between the door and other vehicle systems, the left door controller is responsible for receiving and processing signals from the door switch. After receiving the one-button wake-up signal, the left door controller will perform signal verification and format conversion on the one-button wake-up signal, and then send the processed wake-up unlock signal to the electronic rearview mirror via the CAN bus.
[0054] After receiving the wake-up unlock signal from the left door controller, the electronic rearview mirror of this embodiment will light up within a predetermined time (such as within 3 seconds), providing the driver with a clear view of the left, right and rear sides of the vehicle.
[0055] This allows the driver to start the vehicle or observe the rear view without having to manually adjust the rearview mirror, improving driving safety and convenience. In addition, through the linkage control of the door switch and the electronic rearview mirror, the intelligent control of the vehicle system is realized, which enhances the vehicle's sense of technology and user experience.
[0056] This embodiment also involves a linkage scenario in the sleeper area. Specifically, in the sleeper area, when a passenger or driver presses the one-touch wake-up button on the sleeper switch, the sleeper switch generates a one-touch wake-up signal. The one-touch wake-up signal is then sent to the right door controller through the wiring harness. Similar to the left door controller, the right door controller is also responsible for receiving and processing signals from the door switch. After receiving the one-touch wake-up signal, the right door controller will process it and send the processed wake-up unlock signal to the electronic rearview mirror via the CAN line.
[0057] After receiving the wake-up unlock signal from the right door controller, the electronic rearview mirror will also light up within a predetermined time (such as 3 seconds), providing passengers or drivers with a clear view of the left, right and rear sides of the vehicle. This scenario allows passengers or drivers to easily wake up the electronic rearview mirror in the sleeping area and observe the situation behind the vehicle without moving to the main driving seat.
[0058] This embodiment also involves the use scenario of the front passenger seat area. The implementation steps include: In the passenger seat area, when the passenger presses the one-touch wake-up button on the right door switch 8, the switch immediately generates a one-touch wake-up signal. The one-touch wake-up signal is sent to the right door controller 7 through the wiring harness.
[0059] After receiving the signal, the right door controller 7 processes it, such as signal verification, format conversion, etc., to ensure the reliability of the signal. The processed wake-up unlock signal is sent to the electronic rearview mirror 1 through the CAN bus.
[0060] After receiving the wake-up unlocking signal from the right door controller 7, the electronic rearview mirror 1 will light up within a predetermined time (such as within 3 seconds) to provide the driver and passengers with a clear view of the left, right and rear sides of the vehicle.
[0061] In this way, the electronic rearview mirror can be easily awakened in the passenger seat area, which helps the driver and passengers to quickly observe the surrounding conditions of the vehicle when needed and improve driving safety. In addition, the intelligent control of the vehicle system is realized through the linkage control of the door switch and the electronic rearview mirror.
[0062] This embodiment also involves the implementation process of waking up the electronic rearview mirror by opening the door when the door is not locked. The specific implementation steps include: When the vehicle door is not locked and the passenger opens the door to get in, the door lock switch 5 or the door lock switch 9 will be triggered to generate an action signal.
[0063] The action signal is transmitted to the corresponding left door controller 4 or right door controller 7 .
[0064] After receiving the signal, the left door controller 4 or the right door controller 7 will process it and generate a wake-up unlock signal, which is then sent to the electronic rearview mirror 1 via the CAN line.
[0065] After the electronic rearview mirror 1 receives the wake-up unlock signal, it will light up within 3 seconds.
[0066] It can be seen that in this embodiment, when the door is opened, the state of the door lock switch changes, thereby generating an electrical signal. The electrical signal is transmitted to the door controller, which determines whether the door is opened based on the change in the signal. If the vehicle is not locked and the door is opened, the door controller generates a wake-up unlock signal and sends it to the control unit of the electronic rearview mirror through the CAN bus. After receiving the signal, the control unit of the electronic rearview mirror controls the electronic rearview mirror to light up.
[0067] In this way, the automatically lit electronic rearview mirror helps the driver and passengers observe the surrounding conditions of the vehicle when opening the door and getting in the car, avoiding potential safety hazards.
[0068] In some specific embodiments, in order to ensure the communication reliability between the electronic rearview mirror, the left door switch, the left door controller, the door lock switch, the right door controller, the right door switch and the sleeper switch, the specific implementation process of the CAN line communication of this embodiment is as follows: in the above scenario, both the left door controller and the right door controller send the processed wake-up unlock signal to the electronic rearview mirror through the CAN line.
[0069] like Figure 3 As shown in the figure, the specific implementation process of CAN line communication is as follows: S301: The controller encodes the processed wake-up unlock signal according to the CAN communication protocol to generate a CAN message.
[0070] S302: The controller sends the encoded CAN message to the CAN bus via the CAN transceiver.
[0071] CAN messages are transmitted on the CAN bus, and the controller monitors and receives these messages.
[0072] S303: After receiving the CAN message, the control unit of the electronic rearview mirror decodes it and extracts the wake-up unlocking signal.
[0073] S304: The control unit of the electronic rearview mirror controls the electronic rearview mirror to light up according to the decoded wake-up unlocking signal.
[0074] Through CAN line communication, fast and reliable information exchange between vehicle systems is achieved, providing a solid technical foundation for the linkage control of door control and electronic rearview mirrors.
[0075] Furthermore, as a refinement and expansion of the specific implementation of the above embodiment, in order to further illustrate an implementation process in this embodiment, it can ensure that the electronic rearview mirror is activated at any time, and the electronic rearview mirror system can enter a dormant state at an appropriate time to reduce the consumption of the vehicle battery. The method also includes the following specific steps: When the driver presses the lock button of the remote control key, a remote lock signal is generated, and the remote lock signal is transmitted to a receiving device inside the vehicle via a wireless method (such as radio frequency communication).
[0076] The controller inside the vehicle processes the signal after receiving the remote control vehicle locking signal.
[0077] Specifically, the left door controller serves as a key node for signal processing and is used to transmit the vehicle locking signal to the electronic rearview mirror through the CAN bus.
[0078] After the electronic rearview mirror receives the car locking signal from the left door controller, it turns off the screen and enters the standby state.
[0079] If there is no other action, the electronic rearview mirror system will automatically enter the dormant state after another 5 minutes. At this time, the vehicle current consumption will be reduced to a very low level (less than 2mA) to reduce the consumption of the vehicle battery.
[0080] In sleep mode, the electronic rearview mirror system will maintain low power operation, but can still respond to wake-up signals, such as restarting the vehicle, long pressing the power button, etc.
[0081] When receiving the wake-up signal, the electronic rearview mirror system will exit the sleep state and return to normal working mode.
[0082] This embodiment uses the automatic sleep function to enable the electronic rearview mirror to enter a low-power state when not in use, thereby reducing the consumption of the vehicle battery. The driver does not need to manually turn off the electronic rearview mirror, but only needs to press the lock button of the remote control key, and the electronic rearview mirror will automatically turn off the screen and enter a sleep state, thereby improving the convenience and comfort of the user.
[0083] In some specific embodiments, when the lock button on the left door switch is pressed, the lock signal is transmitted to the left door controller, and the left door controller transmits the lock signal to the electronic rearview mirror through CAN. The electronic rearview mirror immediately turns off the screen and enters the standby state. If there is no other action, the system enters the sleep state after a few minutes, and the sleep current is less than 2mA.
[0084] In this embodiment, when the lock button on the right door switch is pressed, the lock signal is transmitted to the right door controller 7, and the right door controller transmits the lock signal to the electronic rearview mirror through CAN. The electronic rearview mirror immediately turns off the screen and enters the standby state. If there is no other action, the system will enter the sleep state after 5 minutes, and the sleep current is less than 2mA.
[0085] When the driver turns off the vehicle and gets off, if there is no other action within 2 minutes, the electronic rearview mirror 1 will automatically enter the standby state. If there is no other action, the system will enter the sleep state after another 5 minutes, and the sleep current is less than 2mA.
[0086] It can be seen that when the driver presses the lock button on the right door switch or gets off the vehicle after the vehicle is turned off and does not take any other action within a certain period of time, the electronic rearview mirror will automatically enter the standby state and then enter the dormant state. In the dormant state, the battery consumption is reduced. The automatic dormancy function eliminates the need for the driver to manually turn off the electronic rearview mirror, which improves the convenience of use. When the driver approaches the vehicle again or needs to use it, the electronic rearview mirror can respond quickly and return to normal working state, improving the user experience.
[0087] It should be understood that the order of execution of the steps in the above embodiment does not necessarily mean the order of execution. The execution order of each process should be determined by its function and internal logic, and should not constitute any limitation on the implementation process of the embodiment of the present invention.

[0093] For the device of the present application, the operation process and technical implementation of sending a signal through a remote control key to unlock the car door and light up the electronic rearview mirror inside the car. First, the user carries a paired remote control key 3, and when approaching the vehicle but not entering the vehicle, presses the unlock button on the remote control key 3. This action triggers the signal transmitting device inside the remote control key 3, which immediately sends out a wireless signal containing a specific identification code and an unlocking instruction.
[0094] The left door controller 4, as a key component in the vehicle responsible for receiving and processing the signal, has a built-in signal receiving module that decodes and verifies the signal after receiving the wireless signal sent by the remote control key 3. Once it is confirmed that the identification code in the signal matches the preset one of the vehicle and the command is a valid unlocking command, the left door controller 4 processes the signal.
[0095] During the processing, the left door controller 4 first sends an unlocking command to the door locking mechanism to unlock the door. Then, the left door controller 4 sends a signal including a wake-up and lighting command to the electronic rearview mirror 1 via the CAN bus inside the vehicle.
[0096] After receiving the signal through the CAN line, the electronic rearview mirror 1 parses and executes the command. According to the preset program logic, the electronic rearview mirror 1 will complete the lighting operation within 3 seconds after receiving the command and enter the working state.
[0097] In this embodiment, when the user opens the door and enters the vehicle, he can clearly observe the video information displayed on the electronic rearview mirror 1. The video information includes real-time images of the left and right sides and the rear of the vehicle, or other information related to the vehicle status, navigation, etc., so as to help the user quickly and comprehensively understand the environmental conditions around the vehicle after getting in the vehicle, thereby improving driving safety.
[0098] It should be noted that during the entire process, the signal transmission and processing between the various components are completed automatically, and any abnormalities that occur during the signal transmission or processing of the device can be handled in a timely manner, thereby ensuring the stability and reliability of the system.
[0099] The components described in this embodiment, such as the remote control key 3 , the left door controller 4 and the electronic rearview mirror 1 , are all standard configurations already on the vehicle or functional modules that can be realized through simple modification.
[0100] Before getting into the car, users can unlock the doors and light up the electronic rearview mirrors through simple remote control operations, thereby improving the user experience and driving safety.
[0101] The device of this embodiment can also meet the linkage use of various scenarios, such as waking up the electronic rearview mirror with one button in the main driver's seat.
[0102] When the user approaches the vehicle and is ready to enter the main driver's seat, he can press the one-touch wake-up button on the left door switch 2. After pressing the wake-up button, the left door switch 2 will immediately generate a one-touch wake-up signal. This signal is quickly transmitted to the left door controller 4 through the internal wiring harness. As an important signal processing unit in this system, the left door controller 4 is responsible for receiving and processing signals from various switches.
[0103] After receiving the one-key wake-up signal, the left door controller 4 processes it and generates a corresponding wake-up unlock signal. This signal is not only used to unlock the door, but also used to activate the electronic rearview mirror 1. Through the built-in CAN line communication interface, the left door controller 4 sends the processed wake-up unlock signal to the electronic rearview mirror 1.
[0104] After receiving the wake-up unlocking signal from the left door controller 4, the electronic rearview mirror 1 will complete the lighting process within 3 seconds, so as to ensure that the user has enough time to observe and understand the environment around the vehicle, especially the left, right and rear sides, after getting in the vehicle.
[0105] It should be noted that the lighting of the electronic rearview mirror 1 not only provides visual convenience, but also enhances the safety of the user in the process of getting on the vehicle. Through the electronic rearview mirror 1, the user can clearly see obstacles, other vehicles or pedestrians around the vehicle.
[0106] As a preferred implementation method of this embodiment, the left door controller will send a door unlocking signal to the display only after receiving three signals and judging the relevant logic: the unlocking signal of the remote control key, the unlocking signal of the door control switch, and the unlocking signal of the door lock body. The state of the door needs to be judged, and the door needs to be in a locked state.
[0107] The right door controller will send a door unlocking signal to the display only after receiving three signals and judging the relevant logic: the unlocking signal of the berth switch, the unlocking signal of the door control switch, and the unlocking signal of the door lock body. The state of the door needs to be judged and the door needs to be in a locked state.
