[0003] In current technology, reversing camera systems capture images of the area behind the vehicle using a camera installed at the rear of the car and display them on an in-car screen. This allows the driver to visually observe the situation behind the vehicle and simultaneously check the side mirrors to determine if there are any obstacles around the vehicle. While reversing, the driver can combine the information displayed in the side mirrors with the image of the area behind the vehicle on the in-car screen to determine the relative position of the vehicle and any obstacles.

[0036] Exemplary embodiments will now be described in detail, examples of which are illustrated in the accompanying drawings. When the following description relates to the drawings, unless otherwise indicated, the same numbers in different drawings represent the same or similar elements. The embodiments described in the following exemplary embodiments do not represent all embodiments consistent with this application.

[0037] Rather, they are merely examples of apparatuses and methods consistent with some aspects of this application as detailed in the appended claims.

[0038] This application discloses a vehicle that, when in reverse gear, displays distance indication information in the exterior rearview mirrors, thereby improving the efficiency of the vehicle's reversing distance display. For ease of understanding, some concepts involved in this application are explained below.

[0039] 1) A rearview mirror is a mirror installed on a vehicle to help the driver observe the situation behind the vehicle. Rearview mirrors are generally divided into two types: interior rearview mirrors and exterior rearview mirrors. The interior rearview mirror is located in the center of the front of the vehicle and can be used to see the situation behind the vehicle through reflection. The exterior rearview mirror is usually installed on the door or the outside of the door, and the driver can observe the situation on both sides of the vehicle through the exterior rearview mirror.

[0040] 2) Radar is a technological system that uses radio waves to detect the position, speed, and other characteristics of objects. Its working principle is to emit electromagnetic waves (usually microwaves) and then receive the reflected signals to determine information such as the target's position, distance, direction, and speed.

[0041] 3) A radar group usually refers to a system consisting of multiple radars used to realize various advanced driver assistance system functions. In this application, the radar can be installed at the front, rear, side or top of the vehicle to monitor the environment around the vehicle and improve driving safety and automation level.

[0042] 4) Reverse gear is a gear in a vehicle's transmission, and its main function is to allow the vehicle to move backward. When the driver shifts the transmission into reverse gear, the vehicle's power transmission system changes its rotation direction, causing the wheels to rotate in the opposite direction, thus moving the vehicle backward.

[0043] Please refer to Figure 1 , Figure 1 This is a schematic diagram of the structure of a vehicle according to one embodiment of this application. Figure 1 As shown, the vehicle 100 includes an exterior rearview mirror 100a, a controller module 100b, and at least one radar 100c;

[0044] The exterior rearview mirror 100a includes an electronic display module 01; the display of the electronic display module 01 is disposed in the mirror surface of the exterior rearview mirror 100a;

[0045] The controller module 100b is electrically connected to the electronic display module 01, and the controller module 100b is electrically connected to at least one radar 100c.

[0046] The controller module 100b is used to control the electronic display module 01 to display distance indication information based on radar data collected by at least one radar 100c when the vehicle 100 is in reverse gear. The distance indication information is used to indicate the distance between obstacles around the vehicle 100 and the vehicle 100.

[0047] Optionally, the controller module 100b is used to control the electronic display module 01 to display distance indication information when the vehicle 100 is in reverse gear, based on radar data collected by at least one radar 100c, and when the distance between the vehicle 100 and obstacles around the vehicle 100 is less than a distance threshold.

[0048] The aforementioned at least one radar may comprise multiple radar groups, with each radar group containing at least two radars. At least one radar can be used to acquire the distance from the vehicle to an obstacle, which is an object that appears in the vehicle's travel path and affects the vehicle's movement. Obstacles may include, but are not limited to, pedestrians, other vehicles, roadblocks, etc.

[0049] The aforementioned electronic display module includes a display, which can be used to display images, video information, or signals generated by the vehicle's controller module or other electronic devices, such as the distance between the vehicle and an obstacle when the vehicle is reversing.

[0050] The aforementioned radar data is data collected from the vehicle's surroundings by at least one radar installed on the vehicle. Specifically, the radar data may be data used to detect obstacles in the environment surrounding the vehicle, and the radar data includes, but is not limited to:

[0051] 1) Distance data: The distance between the obstacle and the vehicle.

[0052] 2) Location information: The position of the obstacle relative to the vehicle, specifically whether the obstacle is currently directly behind or to the side of the vehicle.

[0053] 3) Speed ​​information: Whether the obstacle is moving, and if the obstacle is moving, its current speed.

[0054] 4) Angle information: The angle information of the obstacle relative to the vehicle, that is, the direction of the obstacle.

[0055] Optionally, the controller module 100b may include a radar controller, a gear position controller, and a body controller; the radar controller is electrically connected to the radar, and the body controller is electrically connected to the radar controller, the gear position controller, and the electronic display module respectively.

[0056] Optionally, the controller module 100b described above can be a single controller, which simultaneously functions as a radar controller, gear shift controller, and vehicle body controller. In this example, the controller can implement specified vehicle functions based on its internal signal transmissions.

[0057] The aforementioned radar controller is used to control whether the radar's detection function is turned on or off.

[0058] The aforementioned gear position controller is used to control the gears of the vehicle.

[0059] The aforementioned body controller is used to receive signals sent by the gear position controller and the radar controller, and send specified signals to the vehicle according to the received signals to enable the vehicle to perform specified functions. For example, after receiving the reverse gear signal sent by the gear position controller, the body controller sends a wake-up signal to the radar controller to activate the radar controller.

[0060] In this embodiment of the application, during the driving of the vehicle 100, the driver can manually / automatically switch the gear to reverse. After the gear of the vehicle 100 is switched to reverse, the controller module 100b activates at least one radar 100c and acquires the radar data collected by at least one radar 100c. Based on the radar data, it generates distance indication information and displays it in the control electronic display module 01.

[0061] The aforementioned distance indication information can be displayed in the display of the control electronic display module 01 in the form of numbers or text, and the driver can obtain the distance indication information by observing the mirror surface of the exterior rearview mirror 100a.

[0062] Optionally, in the case where the controller module 100b includes a radar controller, a gear position controller, and a body controller; the radar controller is electrically connected to the radar, and the body controller is electrically connected to the radar controller, the gear position controller, and the electronic display module respectively, when the vehicle 100 is in reverse gear, the gear position controller in the controller module 100b sends a reverse gear signal to the body controller in the controller module 100b. After receiving the reverse gear signal, the body controller sends a wake-up signal to the radar controller in the controller module 100b to activate the radar controller, enabling the radar controller to control at least one radar to enter the working state, collect the distance between the vehicle 100 and obstacles around the vehicle 100, and then send the distance signal containing the distance to the body controller. After receiving the distance signal, the body controller converts the distance signal into a control signal and sends it to the electronic display module 01. After receiving the control signal, the electronic display module 01 displays distance indication information.

[0063] In this embodiment of the application, the above-mentioned electrical connection includes at least one of physical connection and wireless connection, wherein the physical connection may include, but is not limited to, any one of connection via data cable and direct soldering; specifically, for example, when the controller module 100b, the electronic display module 01 and at least one radar 100c communicate using a CAN (Controller Area Network) bus, the controller module 100b can be physically connected to the electronic display module 01 and at least one radar 100c respectively via a CAN cable.

[0064] Wireless connectivity can include, but is not limited to, any one of wireless local area network (WLAN) communication and Bluetooth connectivity. Specifically, for example, if both the vehicle's controller module 100b and electronic display module 01 support Bluetooth communication, the controller module 100b can wirelessly connect to the electronic display module 01 and at least one radar 100c via a wireless network.

[0065] In this embodiment, an electronic display module is provided in the exterior rearview mirror of the vehicle 100. When the vehicle 100 is in reverse gear, the electronic display module can display distance indication information related to obstacles detected by the vehicle's radar. Specifically, the controller module 100b can acquire radar data collected by at least one radar 100c, obtain distance information between the vehicle 100 and obstacles from the radar data, and then display distance indication information on the mirror surface of the exterior rearview mirror 100a of the vehicle 100 based on the distance information. During the reversing process, the driver can obtain the surrounding status of the vehicle and the distance between the vehicle and surrounding obstacles based on the distance indication information. This expands the method for displaying reversing distance, improves the efficiency of reversing distance display, enables the driver to make more accurate driving operation judgments, and improves the accuracy of reversing distance judgment.

[0066] based on Figure 1 Please refer to Figure 2 , Figure 2 This is a schematic diagram of the structure of at least one radar according to an embodiment of this application. Figure 2 As shown, at least one radar package 100c includes at least one group of radars from the following: left radar group 03, right radar group 04, and rear radar group 05.

[0067] Left radar group 03 includes at least one of a left radar and a left rear radar; right radar group 04 includes at least one of a right radar and a right rear radar; rear radar group 05 includes at least one rear radar.

[0068] The controller module 100b is configured to control the electronic display module 01 to display a first distance indicator when the vehicle 100 is in reverse gear, provided that at least one radar 100c includes the left radar group 03. The first distance indicator is used to indicate the distance between the vehicle 100 and an obstacle detected by the radar in the left radar group 03.

[0069] The controller module 100b is configured to control the electronic display module 01 to display a second distance indicator when the vehicle 100 is in reverse gear, provided that at least one radar 100c includes the right radar group 04. The second distance indicator is used to indicate the distance between the vehicle 100 and an obstacle detected by the radar in the right radar group 04.

[0070] The controller module 100b is configured to control the electronic display module 01 to display a third distance indicator when the vehicle 100 is in reverse gear, provided that at least one radar 100c includes a rear radar group; the third distance indicator is used to indicate the distance between the vehicle 100 and an obstacle detected by the radar in the rear radar group 05.

[0071] Among them, the left radar group 03 is the radar group located on the left side of the vehicle with the front of the vehicle as the front direction as the front direction, the left radar is the radar located on the left side of the vehicle with the front of the vehicle as the front direction as the front direction, and the left rear radar is the radar located behind the left radar with the front of the vehicle as the front direction as the rear direction.

[0072] Among them, the right radar group 04 is the radar group located on the right side of the vehicle with the front of the vehicle as the front direction. The right radar is the radar located on the right side of the vehicle with the front of the vehicle as the front direction. The right rear radar is the radar located behind the right radar with the front of the vehicle as the front direction.

[0073] Among them, the rear radar group 05 is a radar group located at the rear of the vehicle body with the front of the vehicle as the direct front direction. The radar group includes at least one rear radar, which is a radar located at the rear of the vehicle body with the front of the vehicle as the direct front direction.

[0074] In this embodiment of the application, when the vehicle 100 is in reverse gear, the controller module 100b can simultaneously activate different radar groups of the vehicle 100 (e.g., left radar group 03, right radar group 04 and rear radar group 05). The activated different radar groups collect data from different locations around the vehicle 100. The data from different locations includes the distance between the vehicle 100 and obstacles at different locations around the vehicle 100.

[0075] In this embodiment, when the vehicle 100 is in reverse gear, the controller module 100b can activate the left radar group 03. The left radar in the left radar group 03 acquires radar data within the left range of the vehicle 100, and the left rear radar acquires radar data within the left rear range of the vehicle 100. After acquiring at least two radar data, the left radar group 03 combines the at least two radar data to obtain comprehensive information. The comprehensive information is used to indicate the distance between the vehicle 100 and the nearest obstacle in a straight line within the left and left rear ranges of the vehicle 100. The left radar group 03 packages the distance value into a CAN signal and sends it to the controller module 100b. After receiving the CAN signal, the controller module 100b acquires the distance value and converts the distance value into a control signal, which is then sent to the electronic display module 01. After receiving the control signal, the electronic display module 01 displays a first distance prompt on the display according to the control signal.

[0076] In this embodiment, when the vehicle 100 is in reverse gear, the controller module 100b can activate the right radar group 04. The right radar in the right radar group 04 acquires radar data within the right range of the vehicle 100, and the right rear radar acquires radar data within the right rear range of the vehicle 100. After acquiring at least two radar data, the right radar group 04 combines the at least two radar data to obtain comprehensive information. The comprehensive information is used to indicate the distance between the vehicle 100 and the nearest obstacle in a straight line within the right and right rear ranges of the vehicle 100. The right radar group 04 packages the distance value into a CAN signal and sends it to the controller module 100b. After receiving the CAN signal, the controller module 100b acquires the distance value in the CAN signal and converts the acquired distance value into a control signal, which is then sent to the electronic display module 01. After receiving the control signal, the electronic display module 01 displays a second distance prompt on the display according to the control signal.

[0077] In this embodiment, when the vehicle 100 is in reverse gear, the controller module 100b can activate the rear radar group 05. At least one rear radar in the rear radar group 05 acquires radar data within the rear range of the vehicle 100. The rear radar group 05 obtains the distance value between the vehicle 100 and the nearest obstacle in a straight line within the rear range of the vehicle 100 from the radar data. The rear radar group 05 packages the distance value into a CAN signal and sends it to the controller module 100b. After receiving the CAN signal, the controller module 100b acquires the distance value in the CAN signal and converts the acquired distance value into a control signal, which is then sent to the electronic display module 01. After receiving the control signal, the electronic display module 01 displays a third distance prompt on the display according to the control signal.

[0078] The first distance indicator is used to indicate the distance in a straight line from the nearest obstacle to the vehicle 100 within the range to the left and left rear of the vehicle 100; the second distance indicator is used to indicate the distance in a straight line from the nearest obstacle to the vehicle 100 within the range to the right and right rear of the vehicle 100; and the third distance indicator is used to indicate the distance in a straight line from the nearest obstacle to the vehicle 100 within the range to the rear of the vehicle 100.

[0079] In this embodiment of the application, the first distance prompt, the second distance prompt, and the third distance prompt may be displayed in the electronic display module 01 in the form of numbers or graphics.

[0080] Optionally, when the first distance prompt, the second distance prompt, and the third distance prompt are displayed, the controller module 100b of the vehicle 100 controls the exterior rearview mirror 100a of the vehicle to emit a prompt sound for a specified duration. In response to the vehicle 100 exiting the reverse gear state, the controller module 100b controls the exterior rearview mirror 100a of the vehicle to cancel emitting the prompt sound.

[0081] In this embodiment, when the first distance indicator, the second distance indicator, and the third distance indicator are displayed, the controller module 100b, in response to receiving the reversing operation, cancels the display of the first distance indicator, the second distance indicator, and the third distance indicator. It should be noted that in this example, the display of the first distance indicator, the second distance indicator, and the third distance indicator can be a single indicator, for example, only the first distance indicator is displayed; or the second distance indicator is displayed; or the third distance indicator is displayed; or at least two distance indicators can be displayed, for example, the first distance indicator and the second distance indicator are displayed simultaneously; or the first distance indicator and the third distance indicator are displayed simultaneously; or the second distance indicator and the third distance indicator are displayed simultaneously. All three distance indicators can also be displayed simultaneously.

[0082] In this embodiment of the application, the vehicle 100 includes multiple radar groups located at different positions on the vehicle body. The radar groups at different positions can obtain the distance values ​​between the vehicle 100 and obstacles around different positions on the vehicle body. Since the radar groups at different positions can capture the distance values ​​between the vehicle 100 and obstacles within a specified range, the obtained distance values ​​are more accurate. Displaying the distance values ​​in the electronic display module 01 can improve the efficiency of the reversing distance display, enabling the driver to make more accurate driving operation judgments and improve the accuracy of the reversing distance judgment.

[0083] based on Figure 2 Please refer to Figure 3 , Figure 3 This is a schematic diagram of the structure of an exterior rearview mirror according to one embodiment of this application. Figure 3 As shown, the exterior rearview mirrors include a left rearview mirror 06 and a right rearview mirror 07;

[0084] The controller module 100b is used to control the electronic display module 01 to display a first distance indicator on the surface of the left rearview mirror 06 when the vehicle 100 is in reverse gear, provided that at least one radar 100c includes the left radar group 03.

[0085] The controller module 100b is used to control the electronic display module 01 to display a second distance indicator on the surface of the right rearview mirror 07 when the vehicle 100 is in reverse gear, provided that at least one radar 100c includes the right radar group 04.

[0086] The controller module 100b is used to control the electronic display module 01 to display a third distance indicator on the mirrors of the left rearview mirror 06 and the right rearview mirror 07 when the vehicle 100 is in reverse gear, provided that at least one radar 100c includes a rear radar group 05.

[0087] Among them, the left rearview mirror 06 is the external rearview mirror on the left side of the vehicle with the front of the car as the front direction; the right rearview mirror 07 is the external rearview mirror on the right side of the vehicle with the front of the car as the front direction.

[0088] In this embodiment, when the vehicle 100 is in reverse gear, the controller module 100b can activate the left radar group 03. The left radar group 03 detects obstacles within the range on the left side of the vehicle 100 and obtains the distance value between the nearest obstacle to the vehicle 100 and the vehicle 100. The left radar group 03 packages the distance value into a CAN signal and sends it to the controller module 100b. After receiving the CAN signal, the controller module 100b obtains the distance value and converts it into a control signal, which is then sent to the electronic display module 01 of the left rearview mirror 06. After receiving the control signal, the electronic display module 01 displays a first distance prompt on the mirror surface of the left rearview mirror 06 according to the control signal.

[0089] In this embodiment, when the vehicle 100 is in reverse gear, the controller module 100b can activate the right radar group 04. The right radar group 04 detects obstacles within the right side of the vehicle 100 and obtains the distance value between the nearest obstacle to the vehicle 100 and the vehicle 100. The right radar group 04 packages the distance value into a CAN signal and sends it to the controller module 100b. After receiving the CAN signal, the controller module 100b obtains the distance value and converts it into a control signal, which is then sent to the electronic display module 01 of the right rearview mirror 07. After receiving the control signal, the electronic display module 01 displays a second distance prompt on the mirror surface of the right rearview mirror 07 according to the control signal.

[0090] In this embodiment, when the vehicle 100 is in reverse gear, the controller module 100b can activate the rear radar group 05. The rear radar group 05 detects obstacles within the range behind the vehicle 100 and obtains the distance value between the nearest obstacle to the vehicle 100 and the vehicle 100. The rear radar group 05 packages the distance value into a CAN signal and sends it to the controller module 100b. After receiving the CAN signal, the controller module 100b obtains the distance value and converts it into a control signal, which is then sent to the electronic display module 01 of the left rearview mirror 06 and the electronic display module 01 of the right rearview mirror 07. After receiving the control signal, the electronic display module 01 displays a third distance prompt on the mirrors of the left rearview mirror 06 and the right rearview mirror 07 according to the control signal.

[0091] In this embodiment, when the vehicle 100 is in reverse gear, the controller module 100b can activate radar groups at different positions on the vehicle. These radar groups can detect the distance between the vehicle 100 and the nearest obstacle in a straight line in different directions centered on the vehicle body. The distance indicators used to show the distance values ​​detected by the radar groups in different directions are displayed in the side mirrors in the same direction as the radar groups. The distance values ​​detected by the rear radar group 05 of the vehicle 100 are displayed in the side mirrors on the left and right sides of the vehicle 100. Since the driver needs to constantly observe the side mirrors on both sides during reversing, by displaying the distance indicator detected by the left radar group 03 on the left side mirror 06 and the distance indicator detected by the right radar group 04 on the right side mirror 07, the distance between the vehicle 100 and the obstacle can be displayed more accurately from a directional perspective. This effectively ensures the accuracy of the reversing distance display, helps the driver make more accurate driving operation judgments, and improves the accuracy of the reversing distance judgment.

[0092] Based on the solutions shown in the above embodiments, in some embodiments, the distance indication information includes at least one of a distance value and a distance indication icon;

[0093] The distance indicator icon has at least one of its shape and color, used to indicate the range of distances between the vehicle and obstacles around it.

[0094] The aforementioned distance values ​​are used to indicate the distance between the vehicle 100 and the nearest obstacle in a straight line.

[0095] Optionally, when the vehicle 100 is in reverse gear, the controller module 100b can control the electronic display module 01 to display distance indicator icons of different shapes based on radar data collected by at least one radar 100c. The distance indicator icons of different shapes are used to indicate the range of distances between obstacles around the vehicle 100 and the vehicle 100.

[0096] For example, when the distance between the obstacle and the vehicle 100 exceeds a specified distance range, the electronic display module 01 displays a circular distance indicator icon; when the distance between the obstacle and the vehicle 100 does not exceed the specified distance range, the electronic display module 01 displays a triangular distance indicator icon.

[0097] For example, when the distance between the obstacle and the vehicle 100 is less than 0.5 meters, the electronic display module 01 displays a triangle as the distance indicator icon; when the distance between the obstacle and the vehicle 100 is greater than 0.5 meters but less than 1 meter, the electronic display module 01 displays a circle as the distance indicator icon; and when the distance between the obstacle and the vehicle 100 is greater than 1 meter, the electronic display module 01 displays a square as the distance indicator icon.

[0098] In some embodiments, the left rearview mirror 06 and the right rearview mirror 07 of the vehicle 100 can display distance indicator icons of different shapes. The shape of the distance indicator icon is determined by the distance value detected by the radar group in the same direction as the rearview mirror. For example, if the left radar group 03 of the vehicle 100 detects an obstacle on the left side of the vehicle 100 and the distance between the obstacle and the vehicle 100 is 30 centimeters, the distance indicator icon displayed in the left rearview mirror 06 is a triangle; if the right radar group 04 of the vehicle 100 detects an obstacle on the right side of the vehicle 100 and the distance between the obstacle and the vehicle 100 is 80 centimeters, the distance indicator icon displayed in the right rearview mirror 07 is a circle.

[0099] Optionally, when the vehicle 100 is in reverse gear, the controller module 100b can control the electronic display module 01 to display the color of the distance indicator icon based on the radar data collected by at least one radar 100c. Different colored distance indicator icons are used to indicate the range of distances between obstacles around the vehicle 100 and the vehicle 100.

[0100] For example, when the distance between the vehicle 100 and the obstacles around the vehicle 100 exceeds a specified distance range, the distance indicator icon displayed by the electronic display module 01 is yellow; when the distance between the vehicle 100 and the obstacles around the vehicle 100 does not exceed the specified distance range, the distance indicator icon displayed by the electronic display module 01 is red.

[0101] For example, when the distance between the obstacle and the vehicle 100 is less than 0.5 meters, the distance indicator icon displayed by the electronic display module 01 is red; when the distance between the obstacle and the vehicle 100 is greater than 0.5 meters but less than 1 meter, the distance indicator icon displayed by the electronic display module 01 is yellow; when the distance between the obstacle and the vehicle 100 is greater than 1 meter, the distance indicator icon displayed by the electronic display module 01 is green.

[0102] In some embodiments, the left rearview mirror 06 and the right rearview mirror 07 of the vehicle 100 may display distance indicator icons of different shapes. The shape of the distance indicator icon is determined by the distance value detected by the radar group in the same direction as the rearview mirror. For example, if the left radar group 03 of the vehicle 100 detects an obstacle on the left side of the vehicle 100 and the distance between the obstacle and the vehicle 100 is 30 centimeters, the distance indicator icon displayed in the left rearview mirror 06 will be red. If the right radar group 04 of the vehicle 100 detects an obstacle on the right side of the vehicle 100 and the distance between the obstacle and the vehicle 100 is 80 centimeters, the distance indicator icon displayed in the right rearview mirror 07 will be yellow.

[0103] In this embodiment, when the vehicle 100 is in reverse gear, the controller module 100b can display distance indicator icons of different shapes or colors on the mirror surface of the vehicle 100's exterior rearview mirror 100a. These icons indicate the distance range between the vehicle 100 and obstacles around it, expanding the display method of reversing distance. The icons are displayed in different shapes and colors, making them more eye-catching. This allows the driver to obtain reversing distance information more quickly, improving the display efficiency of the vehicle 100 for reversing distance. This enables the driver to make more accurate driving operation judgments and improves the accuracy of reversing distance judgment.

[0104] Please refer to Figure 4 The diagram illustrates a flowchart of a reversing distance display method according to an exemplary embodiment of this application, as shown below. Figure 4 As shown, this method can be used in a controller module, which can be as follows: Figure 1 , Figure 2 as well as Figure 3The method includes a controller module 100b in any vehicle; the vehicle includes an exterior rearview mirror, the controller module, and at least one radar; the exterior rearview mirror contains an electronic display module; the display of the electronic display module is disposed in the mirror surface of the exterior rearview mirror. When the vehicle is in reverse gear, the method may include the following steps:

[0105] Step 410: Based on the radar data collected by at least one radar, control the electronic display module to display distance indication information; the distance indication information is used to indicate the distance between the vehicle and obstacles around the vehicle.

[0106] In this embodiment, an electronic display module is installed in the vehicle's exterior rearview mirror. When the vehicle is in reverse gear, the electronic display module can display distance indication information related to obstacles detected by the vehicle's radar. During the reversing process, the driver can obtain the surrounding status of the vehicle and the distance between the vehicle and surrounding obstacles based on the distance indication information. This expands the method for displaying reversing distance, improves the efficiency of reversing distance display, enables the driver to make more accurate driving operation judgments, and improves the accuracy of reversing distance judgment.

[0107] based on Figure 2 as well as Figure 4 The embodiment shown, Figure 4 The method shown includes at least one radar group of: a left radar group, a right radar group, and a rear radar group; the left radar group includes at least one radar group of: a left radar and a left rear radar; the right radar group includes at least one radar group of: a right radar and a right rear radar; and the rear radar group includes at least one rear radar.

[0108] In the case where at least one radar includes the left radar group, when the vehicle is in reverse gear, the controller module controls the electronic display module to display a first distance indicator; the first distance indicator is used to indicate the distance between the vehicle and an obstacle detected by the radar in the left radar group.

[0109] When at least one radar includes the right-side radar group, and the vehicle is in reverse gear, the controller module controls the electronic display module to display a second distance indicator; the second distance indicator is used to indicate the distance between the vehicle and an obstacle detected by the radar in the right-side radar group.

[0110] In cases where at least one radar includes a rear radar group, when the vehicle is in reverse gear, the controller module controls the electronic display module to display a third distance indicator; the third distance indicator is used to indicate the distance between the vehicle and an obstacle detected by the radar in the rear radar group.

[0111] In this embodiment of the application, the vehicle 100 includes multiple radar groups located at different positions on the vehicle body. The radar groups at different positions can obtain the distance values ​​between the vehicle 100 and obstacles around different positions on the vehicle body. Since the radar groups at different positions can capture the distance values ​​between the vehicle 100 and obstacles within a specified range, the obtained distance values ​​are more accurate. Displaying the distance values ​​in the electronic display module 01 can improve the efficiency of the reversing distance display, enabling the driver to make more accurate driving operation judgments and improve the accuracy of the reversing distance judgment.

[0112] based on Figure 3 as well as Figure 4 The embodiment shown, Figure 4 The method shown includes a left rearview mirror and a right rearview mirror; the method also includes:

[0113] In the case where at least one radar includes the left radar group, when the vehicle is in reverse gear, the controller module controls the electronic display module to display a first distance indicator on the mirror surface of the left rearview mirror.

[0114] In the case where at least one radar includes the right-side radar group, when the vehicle is in reverse gear, the controller module controls the electronic display module to display a second distance indicator on the surface of the right rearview mirror.

[0115] When at least one radar includes a rear radar group, and the vehicle is in reverse gear, the controller module controls the electronic display module to display a third distance indicator on the mirrors of the left and right rearview mirrors.

[0116] In this embodiment, when the vehicle is in reverse gear, the controller module can activate radar groups at different locations on the vehicle. These radar groups can detect the nearest obstacles to the vehicle in different directions centered on the vehicle body, and display the distance values ​​between the obstacles and the vehicle. Distance indicators showing the distance values ​​detected by the radar groups in different directions are displayed in the side mirrors in the same direction as the radar groups. For the distance values ​​detected by the rear radar group, the distance values ​​are displayed in the left and right side mirrors. Since the driver needs to constantly observe the left and right side mirrors while reversing, displaying the distance indicators detected by the left radar group on the left side mirror and the distance indicators detected by the right radar group on the right side mirror provides a more accurate view of the distance between the vehicle and obstacles from a directional perspective. This effectively ensures the accuracy of the reversing distance display, helps the driver make more accurate driving judgments, and improves the accuracy of reversing distance assessment.

[0117] Based on the above Figures 1 to 4The embodiments of the above embodiments are applied to specific scenarios. The embodiments of this application illustrate a method for displaying reversing distance based on a rearview mirror.

[0118] Please refer to Figure 5 The diagram illustrates a system framework diagram of a method according to an exemplary embodiment of this application.

[0119] like Figure 5 As shown, the method in this embodiment consists of a reversing radar 51, a radar controller 52, a gear position controller 53, a body control 54, and a rearview mirror display module 55. The reversing radar 51 is responsible for detecting the distance to obstacles. The radar controller 52 is responsible for converting the radar detection signal into a CAN signal and activating the reversing radar 51, and then transmitting the collected CAN signal to the body control 54. The gear position controller 53 is responsible for collecting and transmitting the vehicle's gear position signal. The body control 54 is responsible for analyzing the gear position signal, activating the radar controller 52, and controlling the rearview mirror display module 55. The rearview mirror display module 55 is responsible for displaying the digital reversing distance.

[0120] In this embodiment, by adding a distance display module to the rearview mirror, the problem of not being able to simultaneously observe obstacles and the distance between the vehicle and obstacles in the rearview mirror is solved. With this solution, information about obstacles can be observed using the mirror's lens, while the distance between the vehicle and obstacles can be observed using the display module in the rearview mirror, increasing driving convenience and safety.

[0121] based on Figure 5 Please refer to Figure 6 The diagram illustrates a control flow chart relating to an exemplary embodiment of this application.

[0122] Step S1: Engage reverse gear in the vehicle.

[0123] In this embodiment, when the vehicle is engaged in reverse / R gear, the gear position controller 53 transmits the gear position signal to the body controller 54 via a CAN signal.

[0124] Step S2: The vehicle body controller 54 analyzes the gear position signal and controls the radar controller 52 to activate the radar.

[0125] After receiving the CAN signal, the body controller 54 processes the gear position signal, then wakes up the radar controller 52, which in turn puts the radar into working mode and then collects distance signals.

[0126] Step S3: The radar acquires distance signals.

[0127] After the radar controller 52 acquires the distance signal, it transmits the acquired distance signal to the body controller 54 in the form of a CAN signal.

[0128] Step S4: Controller signal conversion. The radar signal is converted into a digital tube lighting signal, which controls the display module on the rearview mirror to light up and display the distance to the obstacle.

[0129] After the body controller 54 receives the distance signal, it converts the received distance signal into a control signal and sends it to the rearview mirror display module 55 for display. At this time, the driver can see the nearest obstacle to the vehicle and the distance between the obstacle and the vehicle in the mirror lens.

[0130] Step S5: Determine if the reverse gear is effective.

[0131] If the vehicle does not disengage from reverse gear during the above steps, the rearview mirror display module 55 will continuously display the distance between the obstacle and the vehicle; if the gear is disengaged from reverse / R gear, the display process will stop, the rearview mirror display module will turn off, and the entire reversing distance display process will end.

[0132] In the embodiments of this application, the above solution can enable simultaneous observation of obstacles and the distance between the vehicle and the obstacle in the rearview mirror, which can effectively increase the convenience and safety of the driver during the driving process.
