Description

Technical Field

[0001] The present invention relates to the technical field of vehicle rearview mirror control, and in particular to a control method, system, medium, electronic equipment and vehicle for a folding rearview mirror. Background Art

[0002] The statements in this section merely provide background art related to the present invention and do not necessarily constitute prior art.

[0003] As the most prominent component on the side of a vehicle, the rearview mirror is at high risk of damage from scratches. Most existing vehicles use an automatic folding rearview mirror method, that is, when the vehicle is parked, the controller will control the rearview mirror drive motor to operate, causing the rearview mirror to fold toward the side of the vehicle body. When the vehicle starts, the controller will also control the drive motor to drive the rearview mirror to the memory position.

[0004] The inventors found that the functions implemented by existing rearview mirror control strategies are relatively simple. Most of them can only realize the automatic folding and restoration of the rearview mirror when parking or starting. Under complex road conditions, the folding control of the rearview mirror is generally only based on the distance detection results of the obstacles on the side of the vehicle body, without considering the safety of actual vehicle driving. Summary of the Invention

[0005] In order to address the deficiencies of the prior art, the present invention provides a control method, system, medium, electronic device and vehicle for folding rearview mirrors. When the vehicle speed is less than a set value and the distance between the rearview mirror and the side object is between a safe distance and a dangerous distance, the driver is reminded of the risk of scratching through a first-level warning on the central control display module and a first-level vibration on the steering wheel. At this time, the rearview mirror is not folded; when the vehicle speed is less than a set value and the distance between the rearview mirror and the side object is less than a safe distance, the rearview mirror is folded, and a second-level warning on the central control display module and a second-level vibration on the steering wheel are used to remind the driver that the rearview mirror has been folded. The present invention refines the response measures for different situations, can better remind and assist the driver in driving, and improves the safety of vehicle driving.

[0006] In order to achieve the above object, the present invention adopts the following technical solutions:

At this time, the rearview mirror will not fold; when the distance between the rearview mirror and the object on the side of the vehicle is less than or equal to the danger distance, the central control display module will give a level two warning and the steering wheel will vibrate at level two. At this time, the rearview mirror will fold.

[0012] As an optional implementation method, when the vehicle speed is less than a set value and the lateral distance between the rearview mirror and the object on the side of the vehicle is greater than or equal to the safe distance, the steering wheel does not vibrate and the central control display module does not feedback information.

[0027] The vehicle speed is detected in real time by the vehicle speed detection unit of the body domain control and transmitted to the rearview mirror intelligent detection module. When the vehicle speed is less than or equal to the set value, the rearview mirror intelligent detection module turns on the low-speed distance detection unit; when the vehicle speed is greater than the set value, the rearview mirror intelligent detection module turns off the low-speed distance detection unit.

[0028] After the low-speed distance detection unit is turned on, it detects the lateral distance between the rearview mirror and the object on the side of the vehicle in real time, and transmits the detection result to the rearview mirror control unit of the body domain control module;

[0029] When it is detected that the lateral distance between the rearview mirror and the object on the side of the vehicle is less than the dangerous distance, the rearview mirror control unit controls sending a control signal to the rearview mirror module, and the rearview mirror module controls the rearview mirror to fold. When it is detected that the lateral distance between the rearview mirror and the object on the side of the vehicle is between the safe distance and the dangerous distance or greater than the safe distance, the rearview mirror control unit controls sending a control signal to the rearview mirror module, and the rearview mirror module controls the rearview mirror to remain in the open state.

[0034] As an optional implementation, the control system further includes a central control display module;

[0035] The low-speed distance detection unit transmits the detection results to the central control display module. When it detects that the lateral distance between the rearview mirror and the object on the side of the vehicle is greater than the safe distance, the central control display module does not feedback information;

[0036] When it is detected that the lateral distance between the rearview mirror and the object on the side of the vehicle is between the safe distance and the dangerous distance, the central control display module will provide first-level feedback;

[0037] When it is detected that the lateral distance between the rearview mirror and the object on the side of the vehicle is less than the danger distance, the central control display module will provide secondary feedback; among which, the feedback level of the secondary feedback is greater than the feedback level of the primary feedback.

[0038] As an optional implementation, the lateral distance between the rearview mirror and the object on the side of the vehicle is the lateral distance between the farthest end of the rearview mirror away from the vehicle body and the object on the side of the vehicle.

[0039] As an optional implementation method, data transmission adopts CAN signal transmission.

[0040] A fourth aspect of the present invention provides a computer-readable storage medium having a program stored thereon, which, when executed by a processor, implements the steps in the method for controlling a folding rearview mirror as described in the first aspect of the present invention.

[0041] The fifth aspect of the present invention provides an electronic device, comprising a memory, a processor, and a program stored in the memory and executable on the processor, wherein when the processor executes the program, the steps in the method for controlling a folding rearview mirror as described in the first aspect of the present invention are implemented.

[0042] The sixth aspect of the present invention provides a vehicle, utilizing the control method of the folding rearview mirror described in the first aspect of the present invention; or, including the control system of the folding rearview mirror described in the second aspect of the present invention; or, including the control system of the folding rearview mirror described in the third aspect of the present invention; or, including the computer-readable storage medium described in the fourth aspect of the present invention; or, including the electronic device described in the fifth aspect.

[0043] Compared with the prior art, the present invention has the following beneficial effects:

[0044] 1. The control method, system, medium, electronic device, and vehicle for the folding rearview mirrors of the present invention provide a first-level warning on the central control display module and a first-level vibration on the steering wheel to remind the driver of the risk of a scratch when the vehicle speed is less than a set value and the distance between the rearview mirror and the side object is between a safe distance and a dangerous distance. The rearview mirror does not fold at this time. When the vehicle speed is less than a set value and the distance between the rearview mirror and the side object is less than a safe distance, the rearview mirror folds, and a second-level warning on the central control display module and a second-level vibration on the steering wheel remind the driver that the rearview mirror has been folded. The present invention refines the response measures for different situations, can better remind and assist the driver in driving, and improves vehicle driving safety.

[0045] 2. The control method, system, medium, electronic device and vehicle for the folding rearview mirrors of the present invention, through a combination of multiple signals, enables the rearview mirrors to be folded while the car is driving, thereby reducing the chance of the rearview mirrors being scratched and improving practicality. Moreover, the car only has the function of folding the rearview mirrors when it detects that the vehicle speed is lower than a set value, thereby reducing the chance of the rearview mirrors being folded when the car is driving at high speeds, thereby improving the safety of the present invention.

[0046] 3. Compared with conventional central control display modules that remind drivers, the control method, system, medium, electronic device, and vehicle for the folding rearview mirrors of the present invention have an additional steering wheel vibration reminder method, which can more effectively remind the driver when there is a risk of scratches and when the rearview mirrors are folded. Multiple vibration modes are implemented through multiple signal definitions. When the rearview mirrors are folded, the steering wheel vibrates more strongly, allowing the driver to more effectively understand the vehicle body condition.

[0047] 4. The control method, system, medium, electronic device and vehicle of the folding rearview mirror described in the present invention transmit signals between the rearview mirror intelligent detection module, the body domain control module, the rearview mirror module, the steering wheel module and the central control display module through CAN transmission. Compared with the traditional transmission method using LIN signals in the body domain control module, the signal can be transmitted faster, thereby reducing the risk of damage to the rearview mirror.

[0048] Advantages of additional aspects of the present invention will be given in part in the following description and in part will be obvious from the following description, or will be learned through practice of the present invention. BRIEF DESCRIPTION OF THE DRAWINGS

[0051] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0052] It should be noted that the following detailed descriptions are exemplary and intended to provide further explanation of the present invention. Unless otherwise specified, all technical and scientific terms used herein have the same meaning as commonly understood by those skilled in the art to which the present invention belongs.

[0053] It should be noted that the terms used herein are only for describing specific embodiments and are not intended to limit the exemplary embodiments according to the present invention. As used herein, unless the context clearly indicates otherwise, the singular form is intended to include the plural form. In addition, it should be understood that when the terms "comprise" and / or "include" are used in this specification, they indicate the presence of features, steps, operations, devices, components and / or combinations thereof.

[0054] In the absence of conflict, the embodiments of the present invention and the features thereof may be combined with each other.

[0055] Example 1:

[0056] like Figure 1 As shown, embodiment 1 of the present invention provides a control system for a folding rearview mirror, comprising: a rearview mirror intelligent detection module, a vehicle body domain control module, a rearview mirror module, a steering wheel module, and a central control display module;

[0057] The rearview mirror intelligent detection module includes a low-speed distance measurement unit;

[0058] The body domain control module includes a vehicle speed detection unit, a rearview mirror control unit and a steering wheel control unit.

[0059] First, this embodiment provides parameters defining the CAN signal, as shown in Table 1.

[0060] Table 1: CAN signal parameters

[0061]

[0062]

[0063] In this embodiment, the vehicle speed is detected in real time by the vehicle speed detection unit of the body domain control, and the vehicle speed is transmitted to the rearview mirror intelligent detection module through the CAN signal. When the vehicle speed is lower than 10KM / H, the vehicle speed detection unit sends the parameter "01: Active" in the speed detection signal to the rearview mirror intelligent detection module, and the rearview mirror intelligent detection module turns on the low-speed distance detection unit; when the vehicle speed is greater than 10KM / H, the vehicle speed detection unit sends the parameter "00: NotActive" in the speed detection signal to the rearview mirror intelligent detection module, and the rearview mirror intelligent detection module turns off the low-speed distance detection unit.

[0064] It is understandable that in some other embodiments, the vehicle speed limit can also be set to other values ​​such as 5KM / H, 8KM / H, etc. Those skilled in the art can choose within the range of 0-20KM / H according to specific working conditions, which will not be repeated here.

[0065] When the low-speed distance detection unit is turned on, it detects the lateral distance between the rearview mirror and objects on the side of the car in real time. There are three ranges for distance detection: greater than the safe distance, less than the dangerous distance, and between the safe distance and the dangerous distance.

[0066] The low-speed distance detection unit transmits detection results in real time via CAN signals to the rearview mirror control unit in the vehicle body domain control module. If the distance between the rearview mirror and an object to the side of the vehicle is less than the dangerous distance, the low-speed distance detection unit sends the parameter "10: Dangerous" in the low-speed distance detection signal to the rearview mirror control unit. The rearview mirror control unit then sends the parameter "01: Fold" in the rearview mirror control signal to the rearview mirror module, thereby controlling the mirror to fold.

[0067] When it is detected that the distance between the rearview mirror and the object on the side of the vehicle body is between the safe distance and the dangerous distance, the low-speed distance detection unit sends the parameter "01: Warning" in the low-speed distance detection signal to the rearview mirror control unit, and the rearview mirror control unit sends the parameter "00: Not Fold" in the rearview mirror control signal to the rearview mirror module, and the rearview mirror module controls the rearview mirror to remain in the open state. When it is detected that the distance between the rearview mirror and the object on the side of the vehicle body is greater than the safe distance, the low-speed distance detection unit sends the parameter "00: Safe" in the low-speed distance detection signal to the rearview mirror control unit, and the rearview mirror control unit sends the parameter "00: Not Fold" in the rearview mirror control signal to the rearview mirror module, and the rearview mirror module controls the rearview mirror to remain in the open state.

[0068] The low-speed distance detection unit transmits the detection results to the steering wheel control unit in real time via CAN signals. When it detects that the distance between the rearview mirror and the object on the side of the vehicle body is greater than the safe distance, the low-speed distance detection unit sends the parameter "00: Safe" in the low-speed distance detection signal to the steering wheel control unit, and the steering wheel control unit sends the parameter "00: Not Shake" in the steering wheel vibration signal to the steering wheel module. At this time, the steering wheel does not vibrate;

[0069] When the distance between the rearview mirror and the object on the side of the vehicle body is detected to be between the safe distance and the dangerous distance, the low-speed state distance detection unit sends the parameter "01: Warning" in the low-speed state distance detection signal to the steering wheel control unit, and the steering wheel control unit sends the parameter "01: Level 1 Shake" in the steering wheel vibration signal to the steering wheel module. At this time, the steering wheel vibrates at the first level to remind the driver that the rearview mirror is at risk of being scratched; when the distance is detected to be less than the dangerous distance, when the distance between the rearview mirror and the object on the side of the vehicle body is less than the dangerous distance, the low-speed state distance detection unit sends the parameter "10: Dangerous" in the low-speed state distance detection signal to the steering wheel control unit, and the steering wheel control unit sends the parameter "10: Level 2 Shake" in the steering wheel vibration signal to the steering wheel module. At this time, the steering wheel vibrates at the second level to remind the driver that the rearview mirror has been folded;

[0070] The low-speed distance detection unit transmits the detection results to the central control display module in real time via CAN signals. When it detects that the distance between the rearview mirror and the object on the side of the vehicle is greater than the safe distance, the low-speed distance detection unit sends the parameter "00: Safe" in the low-speed distance detection signal to the central control display module. At this time, the central control display module does not provide any feedback.

[0071] When the distance between the rearview mirror and an object on the side of the vehicle is detected to be between the safe distance and the dangerous distance, the low-speed distance detection unit sends the parameter "01: Warning" in the low-speed distance detection signal to the central control display module. At this time, the central control display module issues a first-level feedback, and the central control display module reminds the driver through text, images and sound that there is a risk of scratching the rearview mirror at this time;

[0072] When it is detected that the distance between the rearview mirror and the object on the side of the vehicle body is less than the dangerous distance, the low-speed distance detection unit sends the parameter "10: Dangerous" in the low-speed distance detection signal to the central control display module. At this time, the central control display module issues a secondary feedback. The central control display module reminds the driver through text images and sounds that are larger than the primary feedback. The rearview mirror and the object on the side of the vehicle body are less than the dangerous distance, and the rearview mirror has been folded.

[0073] It is understandable that in some other embodiments, because the rearview mirror intelligent detection module detects the distance between the farthest end of the rearview mirror and the obstacle, therefore, on the premise that the optimal use angle of the rearview mirror can be obtained according to the driver's driving habits (including sitting posture, height, etc.), the angle range between the optimal use angle and the fully folded angle is divided into multiple sub-angle intervals. Starting from the optimal angle, one sub-angle interval is folded each time. After folding a sub-angle interval, the rearview mirror intelligent detection module detects the distance to the obstacle. When it is still a level 2 alarm and level 2 feedback, it continues to fold a sub-angle interval until it enters a level 1 alarm and level 1 feedback. At this time, the rearview mirror is no longer folded. This can effectively avoid the rearview mirror from being scratched, and at the same time can effectively ensure a certain rearview function to avoid safety hazards during low-speed driving.

[0074] It is understandable that in some other embodiments, because the rearview mirror intelligent detection module detects the distance between the farthest end of the rearview mirror and the obstacle, therefore, under the premise of being able to obtain the optimal use angle of the rearview mirror according to the driver's driving habits (including sitting posture, height, etc.), the sub-angle interval is not set. From the beginning of folding of the rearview mirror, the distance between the farthest end of the rearview mirror and the obstacle is detected in real time. When there is still a second-level alarm and a second-level feedback, the folding continues until it enters a first-level alarm and a first-level feedback. At this time, the rearview mirror is no longer folded. This can effectively avoid the rearview mirror from being scratched, and at the same time can effectively ensure a certain rearview function, avoiding safety hazards during low-speed driving.

[0075] Example 2:

[0076] Embodiment 2 of the present invention provides a method for controlling a folding rearview mirror, comprising the following steps:

[0077] Get the current real-time vehicle speed and the lateral distance between the rearview mirror and objects on the side of the vehicle;

[0078] When the current vehicle speed is greater than a set value (the set value is 5 km / h, 8 km / h, 10 km / h or other values. Those skilled in the art can select it within the range of 0-20 km / h according to the specific working conditions, which will not be repeated here), the low-speed state distance detection function is turned off; otherwise, the low-speed state distance detection function is turned on and the following process is performed:

[0079] When the distance between the rearview mirror and the object on the side of the vehicle is greater than the danger distance and less than the safety distance, the central control display module will give a level one warning and the steering wheel will vibrate at level one. At this time, the rearview mirror will not fold; when the distance between the rearview mirror and the object on the side of the vehicle is less than or equal to the danger distance, the central control display module will give a level two warning and the steering wheel will vibrate at level two. At this time, the rearview mirror will fold.

[0080] When the vehicle speed is less than the set value and the lateral distance between the rearview mirror and the object on the side of the vehicle is greater than or equal to the safe distance, the steering wheel does not vibrate and the central control display module does not feedback information.

[0081] The vibration level of the secondary vibration is greater than that of the primary vibration, and the feedback level of the secondary feedback is greater than that of the primary feedback.

[0082] The lateral distance between the rearview mirror and the object on the side of the vehicle is the lateral distance from the farthest end of the rearview mirror away from the vehicle body to the object on the side of the vehicle.

[0083] It is understandable that in some other embodiments, because the rearview mirror intelligent detection module detects the distance between the farthest end of the rearview mirror and the obstacle, therefore, on the premise that the optimal use angle of the rearview mirror can be obtained according to the driver's driving habits (including sitting posture, height, etc.), the angle range between the optimal use angle and the fully folded angle is divided into multiple sub-angle intervals. Starting from the optimal angle, one sub-angle interval is folded each time. After folding a sub-angle interval, the rearview mirror intelligent detection module detects the distance to the obstacle. When it is still a level 2 alarm and level 2 feedback, it continues to fold a sub-angle interval until it enters a level 1 alarm and level 1 feedback. At this time, the rearview mirror is no longer folded. This can effectively avoid the rearview mirror from being scratched, and at the same time can effectively ensure a certain rearview function to avoid safety hazards during low-speed driving.

[0084] It is understandable that in some other embodiments, because the rearview mirror intelligent detection module detects the distance between the farthest end of the rearview mirror and the obstacle, therefore, under the premise of being able to obtain the optimal use angle of the rearview mirror according to the driver's driving habits (including sitting posture, height, etc.), the sub-angle interval is not set. From the beginning of folding of the rearview mirror, the distance between the farthest end of the rearview mirror and the obstacle is detected in real time. When there is still a second-level alarm and a second-level feedback, the folding continues until it enters a first-level alarm and a first-level feedback. At this time, the rearview mirror is no longer folded. This can effectively avoid the rearview mirror from being scratched, and at the same time can effectively ensure a certain rearview function, avoiding safety hazards during low-speed driving.

[0087] The data acquisition module is configured to: obtain the current real-time vehicle speed and the lateral distance between the rearview mirror and the object on the side of the vehicle;

[0088] The distance detection and judgment module is configured to: when the current vehicle speed is greater than a set value (the set value is 5 km / h, 8 km / h, 10 km / h, or other values. Those skilled in the art can select a value within the range of 0-20 km / h according to specific working conditions, which will not be repeated here), turn off the low-speed distance detection function; otherwise, turn on the low-speed distance detection function and execute the function of the rearview mirror folding control module;

[0089] The rearview mirror folding control module is configured as follows: when the distance between the rearview mirror and the object on the side of the vehicle is greater than the danger distance and less than the safety distance, the central control display module will issue a level one warning, and the steering wheel will vibrate at level one, and the rearview mirror will not fold; when the distance between the rearview mirror and the object on the side of the vehicle is less than or equal to the danger distance, the central control display module will issue a level two warning, and the steering wheel will vibrate at level two, and the rearview mirror will fold.

[0090] When the vehicle speed is less than the set value and the lateral distance between the rearview mirror and the object on the side of the vehicle is greater than or equal to the safe distance, the steering wheel does not vibrate and the central control display module does not feedback information.

[0091] The vibration level of the secondary vibration is greater than that of the primary vibration, and the feedback level of the secondary feedback is greater than that of the primary feedback.

[0092] The lateral distance between the rearview mirror and the object on the side of the vehicle is the lateral distance from the farthest end of the rearview mirror away from the vehicle body to the object on the side of the vehicle.
