[0040] The present application is further described in detail below in conjunction with the accompanying drawings and specific embodiments. It should be noted that the technical features involved in the various embodiments of the present application described below can be combined with each other as long as they do not conflict with each other. The embodiments described below with reference to the accompanying drawings are exemplary and are intended to be used to explain the present application, and should not be understood as limiting the present application.
[0041] like Figures 1 to 4 As shown, this embodiment provides an electric back door controller for controlling the automatic opening of the back door of a car, including: a control module 2, for example, the control module 2 is a microcontroller unit (MCU), also known as a single chip microcomputer (Single Chip Microcomputer) or a single chip microcomputer, which appropriately reduces the frequency and specifications of the central processing unit (CPU), and integrates memory, timer, USB, A / D conversion, UART, PLC, DMA and other peripheral interfaces, and even LCD drive circuits on a single chip to form a chip-level computer, and perform different combination controls for different application occasions. MCU can be seen in mobile phones, PC peripherals, remote controls, automotive electronics, industrial stepper motors, robot arm control, etc.
[0042] The sensing module is connected to the control module 2 by a signal. The sensing module is used to detect whether the distance between the target terminal and the sensing module is less than a preset distance, and send the detection information to the control module 2. It should be understood that the target terminal can be a car key or a mobile phone. The sensing module is used to detect whether the target terminal is within a preset range. When the target terminal is within the preset distance of the sensing module, the sensing module sends the detection information to the control module 2, so that the control module 2 can perform unlocking control of the back door lock according to the position of the target terminal.
[0043] For example, the sensing module uses Radio Frequency Identification (RFI), the principle of which is to perform contactless data communication between a reader and a target terminal to achieve the purpose of identifying the target.
[0044] The camera module 8 is connected to the control module 2 by signal. The camera module 8 is used to monitor whether the user completes the preset action in the target area and sends the monitoring information to the control module 2. It should be understood that the camera module 8 can be an infrared camera, which is used to record and monitor the target area. When the preset action occurs in the target area, the monitoring information is sent to the control module 2, and the control module 2 controls the unlocking of the back door lock.
[0045] For example, the preset action may include three steps: 1. the foot enters the target area, 2. the foot steps on the projected image of the target area, and 3. the foot exits the target area. If the three steps are complete, it is judged to be valid, and if the three steps are incomplete, it is judged to be invalid.
[0046] The first projection module 5 is connected to the control module by signal and is used to project an image indicating that the back door is closed to the target area; the second projection module 6 is connected to the control module by signal and is used to project an image indicating that the back door is open to the target area; the third projection module 7 is connected to the control module by signal and is used to project a charging status image indicating an image during charging or an image of charging completion to the target area.
[0047] The first projection module 5 is used to project an image indicating that the back door is closed to the target area, and the second projection module 6 is used to project an image indicating that the back door is open to the target area. For example, when the user approaches the vehicle with the target terminal and is less than the preset distance, the sensing module senses the target terminal signal and sends it to the control module 2 through the CAN signal. The control module 2 controls the first projection module 5 to project the projection image of the back door closed, so as to prompt the user to step into the target area where the projection image is located through the projection image.
[0048] Specifically, when a user approaches the vehicle with the car key, the sensing module senses the car key signal and sends it to the control module 2 via the CAN signal. The control module 2 controls the first projection module 5 to project the back door closed image, indicating that the back door is in a closed state at this time. When the back door is opened, the control module 2 controls the second projection module 6 to project the back door open image, indicating that the back door is in an open state at this time. When the user moves away from the vehicle with the car key, the sensing module senses that the car key signal disappears and sends it to the control module 2 via the CAN signal. The control module 2 controls the electric back door controller to close the projection.
[0049] When the user steps on the projected image of the back door closed, the camera module 8 records the entire stepping process: the foot enters the projection area, steps on the projected image of the back door closed, and the foot exits the projection area. The control module 2 determines whether the step is valid. If the three processes are complete, it is judged to be valid; if the three processes are incomplete, it is judged to be invalid.
[0050] If the process is complete, the control module 2 determines that the foot pedal is valid and feeds back to the body control module BCM. The BCM controls the back door lock controller to open the back door. At the same time, the control module 2 controls the first projection module 5 to close the projection image of the back door closed, and controls the second projection module 6 to project the projection image of the back door opened to prompt the user that the back door is opened.
[0051] The user steps on the projected image of the back door opening, and the camera module 8 records the entire process: the foot enters the projection area, steps on the projected image of the back door opening, and the foot exits the projection area. The control module 2 determines whether the footstep is effective; if the three processes are complete, it is judged to be effective, and if the three processes are incomplete, it is judged to be invalid. The control module 2 feeds back to the BCM, and the BCM controls the back door lock controller to close the back door. At the same time, the control module 2 controls the second projection module 6 to close the projected image of the back door opening, and controls the first projection module 5 to project the projected image of the back door closing. The user can quickly determine the switch status of the back door based on the images projected by the first projection module 5 and the second projection module 6, and perform footstepping operations in the projection area, which significantly improves the user's convenience.
[0052] At the same time, the third projection module 7 is used to project an image indicating the charging process or the charging completion image to the target area to remind the user of the charging progress, which is convenient for the user to judge the battery charging status of the vehicle, greatly improving the user's experience. In addition, the present application sets three projection modules, and the projected images are diverse and the switching is smoother.
[0053] In some embodiments, the first projection module 5 includes a first optical-mechanical lens 501 and a first optical-mechanical circuit board 502, the first optical-mechanical circuit board 502 is provided with a first LED lamp, and the first optical-mechanical circuit board 502 is signal-connected to the control module 2. It should be understood that the control module 2 controls the first optical circuit board to control the first LED lamp to project an image indicating that the back door is open. Similarly, the control module 2 controls the first optical circuit board to control the first LED lamp to turn off the projected image.
[0054] In some embodiments, the second projection module 6 includes a second optical-mechanical lens 601 and a second optical-mechanical circuit board 602, the second optical-mechanical circuit board 602 is provided with a second LED light, and the second optical-mechanical circuit board 602 is signal-connected to the control module 2. It should be understood that the control module 2 controls the second optical circuit board to control the second LED light to project an image indicating that the back door is closed. Similarly, the control module 2 controls the second optical circuit board to control the second LED light to turn off the projected image.
[0055] In some embodiments, the third projection module 7 includes a third optical-mechanical lens and a third optical-mechanical circuit board, the third optical-mechanical circuit board is provided with a third LED light, and the third optical-mechanical circuit board is connected to the control module signal. The charging image is a red flashing image projected by the third LED light to the target area, and the charging completion image is a green light image projected by the third LED light to the target area.
[0056] It should be understood that the control module 2 controls the third optical circuit board to control the third LED light to project an image representing the charging process or the charging completion image. Similarly, the control module 2 controls the third optical circuit board to control the third LED light to turn off the projected image.
[0057] For example, when the vehicle is charging, the battery system EMS detects the charging status and transmits a charging signal to the BCM via the CAN bus. The BCM signal is fed back to the control module 2, and the control module 2 controls the third projection module 7 to project an image to indicate the charging process or the charging completion image. For example, red flashing indicates charging, and green stops flashing to indicate charging is complete and charging stops. The battery system EMS detects that there is no charging, and transmits a signal to the BCM via the CAN bus. The BCM controls the control module 2 to turn off the third projection module and stop displaying.
[0058] In some embodiments, the camera module 8 includes an infrared camera lens 801 and a sensor circuit board 802. The infrared camera lens 801 is used to monitor the target area and transmit the monitoring information to the sensor circuit board 802. The sensor circuit board 802 is connected to the control module 2 by signal. It should be understood that the infrared camera image lens recognizes the pedaling action in the target area and transmits it to the sensor circuit board 802 to realize the recognition of the pedal control function.
[0059] In some embodiments, considering the specific setting of the preset distance, the preset distance is 0.5-2 meters, and the specific preset distance is 1 meter or 0.8 meters.
[0060] In some embodiments, the shell includes an upper shell 1 and a lower shell 3, the upper shell 1 is provided with a first mounting hole for installing the sensing module, a second mounting hole for installing the camera module 8, a third mounting hole for installing the first projection module 5, a fourth mounting hole for installing the second projection module 6, and a fifth mounting hole for installing the third projection module 7, the lower shell 3 is provided with a mounting slot for installing the control module 2, and the upper shell 1 and the lower shell 3 are snap-fitted and connected to achieve fixed installation of the sensing module, the camera module 8 and the projection module.
[0061] For example, the lower housing 3 is provided with a positioning column 302 for pressing the control module 2, that is, the control module 2 is positioned by the positioning column 302 of the lower housing 3, and the top block 303 limits the position of the control module 2 to prevent the circuit board from collapsing. The lower housing 3 is then fixed to the upper housing 1 by four bolts 4. The lower housing 3 and the upper housing 1 are provided with mounting holes 301 for passing the bolts 4.
