[0043] 1. Automobile rearview mirror device

[0044] In this embodiment, unless otherwise specified, when referring to a "vehicle rearview mirror device", it refers to an integral device that can play the same rearview role as a conventional rearview mirror. Such a vehicle rearview mirror device can be used as a left rearview mirror or a right rearview mirror on a car.

[0045] Reference Figure 1 In this embodiment, the automotive rearview mirror device includes components such as a mirror body, a fixing unit, a height adjustment unit, a sensor, and a control unit. The mirror body includes components such as a housing and a rear view display component. The rear view display component is mounted on the housing, and the sensor and control unit can be integrated within the housing of the mirror body. The mirror body is mounted on the fixing unit via the height adjustment unit. The fixing unit is mounted to the vehicle body (specifically, a location such as a door) by bonding or rivets, thereby securing the entire automotive rearview mirror device to the vehicle body.

[0046] In this embodiment, when the entire rearview mirror device is fixed on the body of the car, the effect is as follows: Figure 2 shown.

[0047] In this embodiment, the rearward-viewing component in the mirror body is an optical component that performs a rearview function, and can display the situation behind the vehicle to the driver and other passengers. Specifically, a glass lens can be used as the rearward-viewing component. In this case, the mirror body acts like a conventional rearview mirror. By pointing the glass lens toward the rear of the vehicle, light from the rear of the vehicle can be reflected by the glass lens toward the passengers, allowing the passengers to observe the situation behind them.

[0048] In this embodiment, a camera can also be used as a rear visual display component. By orienting the camera's field of view toward the rear of the vehicle, the camera can capture the situation behind the vehicle, obtain a rear image, and transmit the rear image to a display for display. The display can be mounted on the housing of the mirror body as part of the mirror body, allowing passengers to observe the rear situation by observing the position of the mirror body. The display can also be mounted on a location such as the center console within the passenger compartment of the vehicle for passengers to observe.

[0049] In this embodiment, when the rearview mirror device is mounted on the vehicle body, the mirror body is located above or below the fixing unit. Figure 1 As shown, the mirror body is located above the fixed unit. The AA axis is established perpendicular to the ground. The distance between a point on the mirror body (specifically, the lowest point or a special location such as the center of mass) and a point on the fixed unit (specifically, the highest point or a special location such as the center of mass) along the AA axis is the relative height H between the mirror body and the fixed unit.

[0050] In this embodiment, refer to Figure 1 and Figure 2 The height adjustment unit connects the lens body and the fixed unit and controllably adjusts or maintains the relative height H between the lens body and the fixed unit. Specifically, the height adjustment unit can receive external control instructions, where the control instructions indicate a specific value of the relative height H. Under the control of the control instructions, the height adjustment unit drives the lens body to move along the AA axis relative to the fixed unit, that is, to move it in the up and down direction, so that the relative height between the lens body and the fixed unit reaches the specific value of H. After the relative height between the lens body and the fixed unit reaches the specific value of H, the height adjustment unit can fix its own shape, so that the relative height between the lens body and the fixed unit is maintained at the specific value of H.

[0051] In this embodiment, the structure of the height adjustment unit is as follows: Figure 3 As shown. Figure 3The height adjustment unit includes connecting parts, screws, steering wheels and motors. The connecting parts are double-tube structures, including an outer tube connected to the mirror body and a guide tube nested inside the outer tube. A part of the guide tube is exposed outside the outer tube, and the part is connected to one end of the screw.

[0052] Reference Figure 3 The steering wheel is sleeved on the lead screw and connected together by threads. The motor can apply driving force to the steering wheel, and the steering wheel transmits the force to the lead screw, causing the lead screw to rotate relative to the steering wheel. Under the action of the threads, the relative rotation of the lead screw and the steering wheel is converted into the up and down movement of the lead screw. The relative rotation direction of the steering wheel and the lead screw can be controlled by controlling the rotation direction of the motor, and the up and down movement of the lead screw can be controlled by controlling the rotation stroke of the motor. Figure 3 Since the lead screw is connected to the connecting component, and the connecting component is connected to the mirror body, the up and down movement of the lead screw drives the up and down movement of the mirror body, thereby adjusting the relative height H between the mirror body and the fixing unit.

[0053] In this embodiment, the control unit can compile a control instruction according to the rotation direction and rotation stroke of the motor to be controlled, and send the control instruction to the motor, thereby enabling the control unit to control the motor.

[0054] In this embodiment, by using Figure 3 The double-tube structure of the outer tube plus the guide tube shown as a connecting component can achieve smooth adjustment of the height of the lens body and reduce the noise generated by adjusting the lens body up and down.

[0055] In this embodiment, refer to Figure 3 The control unit and sensor can be arranged inside the housing of the mirror body, and the sensor is connected to the control unit via a data cable. An electronic control unit (ECU) can be used as the control unit, and a MEMS vibration sensor can be used as the sensor. The sensor can detect the vibration of the mirror body in real time and obtain vibration data. The vibration data can represent the vibration amplitude, frequency, phase, and other data of the mirror body at a certain sampling moment. In this embodiment, the vibration amplitude is mainly used as the vibration data.

[0056] In this embodiment, the control unit controls the height adjustment unit according to the vibration data detected by the sensor. Specifically, the control unit can perform the following steps:

[0057] S1. Detecting the driving condition information of the vehicle;

[0058] S2. When the driving condition information meets the preset conditions, the sensor is called to dynamically collect vibration data in the form of a time series;

[0059] S3. Dynamically control the relative height adjusted or maintained by the height adjustment unit based on the vibration data in the form of a time series, so that the vibration data remains within the minimum vibration value range.

[0060] In this embodiment, the driving condition information of the car to be detected in step S1 represents the driving condition of the car, such as whether the car is started, the current location (surrounding environment type, such as urban road or highway, etc.), the current speed, etc.

[0061] In step S2, the preset condition can be set to a condition that is very easy to meet, such as "the car is started" or "the whole vehicle self-test is passed", so that the control unit can execute steps S2-S3 under almost any circumstances.

[0062] In step S2, the preset condition can be set to "detecting entry into a highway" or "good road conditions ahead", so that steps S2-S3 are only executed when the road conditions are good and easy for the driver to observe, which helps to reduce the impact of the relative height change of the mirror body on the driver's observation.

[0063] In step S2, the control unit can set a series of sampling times t1, t2, t3, ... t n At sampling time t1, the sensor is called to detect the vibration of the mirror body, thereby obtaining vibration data v1; at sampling time t2, the sensor is called to detect the vibration of the mirror body, thereby obtaining vibration data v2; at sampling time t3, the sensor is called to detect the vibration of the mirror body, thereby obtaining vibration data v3... At sampling time t n Call the sensor to detect the vibration of the mirror body to obtain vibration data v n , thus obtaining vibration data v1, v2, v3...v in the form of a sequence n .

[0064] In this embodiment, it is not necessary to wait until a sufficient number (for example, a specific n) of vibration data v1, v2, v3, ..., v n Instead of starting to execute step S3, step S3 can be executed when vibration data is collected, and step S2 can also be executed to continuously collect vibration data at each sampling moment.

[0065] In this embodiment, when executing step S3, the control unit may i (i is an arbitrary integer) The vibration data v collected i and the next sampling time t i+1 The collected vibration data v i+1 , judge the vibration data v i+1 Relative vibration data v iTo increase or decrease, and according to the magnitude of the increase or decrease, determine the next moment t i+2 To control the relative height between the mirror body and the fixed unit, the value H i+2 , H i+2 The size of the mirror body can make the mirror body at the sampling time t i+2 The vibration data that can be detected v i+2 Relative v i+1 Since the relative height between the mirror body and the fixed unit is mapped to the travel of the steering wheel, the control unit can adjust the relative height between the fixed units to the value H i+2 Generate a control command for the corresponding stroke, send the control command to the motor, and trigger the motor to drive the steering wheel, so that the relative height between the mirror body and the fixed unit is at the sampling time t i+2 Reach H i+2 .

[0066] In this embodiment, the principle of the control unit executing steps S1-S3 is that the vibration of the rearview mirror device is mainly caused by the interaction between the mirror body and the wind. The generated vibration data v is related to multiple parameters, the most significant of which are the relative height H between the mirror body and the fixing unit and the wind speed w (which can be considered to be equal to the driving speed of the car), which can be expressed as v = f(H, w). Therefore, when the vibration data v1, v2, v3, ..., v3 in the form of a time series are detected, n In the case of vibration data, the relative height H between the mirror body and the fixed unit can be negatively feedback controlled according to the change trend of the vibration data, so that the relative height H is adjusted to the target height value, so that the vibration data v1, v2, v3...v n It can converge to the target vibration value. In this embodiment, the target vibration value is the minimum value that the vibration data can reach. Since v = f (H, w) indicates that the vibration data v is also related to the wind speed w, when the wind speed w remains unchanged, the target vibration value can be obtained in the vibration data v1, v2, v3 ... v n After converging to the target vibration value, the relative height H is kept unchanged, so that the vibration data v of the automobile rearview mirror device is maintained near the target vibration value. When the wind speed w changes, the vibration data v will also change instantaneously. If the vibration data v is to be maintained near the same target vibration value, the control unit needs to change the value of the relative height H and find other specific values ​​of the relative height H. This process is a re-executed negative feedback control process. By changing the value of the relative height H, the influence of the change in wind speed w is overcome, so that the vibration data v is always maintained near the same target vibration value.

[0067] In this embodiment, the target vibration value that the vibration data v of the automobile rearview mirror device needs to maintain is the minimum value v that the vibration data can reach. min; In actual control, taking into account the influence of errors, the minimum value v min It is generally not a fixed value, but is within a fixed range, that is, the minimum vibration value range, for example [v min -ε v ,v min +ε v ], where ε v Indicates a very small error value. In this embodiment, the minimum value v min A fixed value is used as an example for explanation.

[0068] Accordingly, when the wind speed w is fixed, in order to keep the vibration data v at the minimum value v min , the relative height H between the mirror body and the fixed unit will reach a specific value H0. Similarly, in actual control, the relative height H between the mirror body and the fixed unit is generally not a fixed value H0 but is within a fixed range, that is, the height value range, for example [H0-ε H ,H0+ε H ], where ε H In this embodiment, the relative height H between the mirror body and the fixing unit is a fixed value H0 as an example for description.

[0069] In this embodiment, f may not be a linear function, and can be determined through calibration experiments, so that the vibration data v1, v2, v3...v n The change trend of H0 can be used to determine the required value more quickly. There is no need to conduct a calibration experiment, that is, there is no need to determine f in advance, and the vibration data v1, v2, v3...v n The change trend of H0 needs to be determined. However, the vibration data v1, v2, v3, etc. are needed to determine the size of H0. n The sequence may be longer.

[0070] The automobile rearview mirror device in this embodiment is provided with a sensor to detect the vibration of the mirror body to obtain vibration data, and a control unit is provided to control the height adjustment unit according to the vibration data, so that the relative height between the mirror body and the fixed unit (car body) can reach a specific position, thereby making the vibration of the mirror body reach a specific degree (set to the minimum degree in this embodiment). Therefore, the vibration degree of the automobile rearview mirror device can be dynamically adjusted by dynamically adjusting the relative height between the mirror body and the fixed unit, which can effectively reduce the vibration of the automobile rearview mirror device, thereby reducing the driving experience degradation caused by the wind noise of the automobile rearview mirror device, and can adjust the shape of the automobile rearview mirror device by adjusting the relative height between the mirror body and the fixed unit, thereby adjusting the overall starting shape of the automobile, reducing the wind resistance of the automobile rearview mirror device, reducing the possibility of turbulence, eddy currents, etc., and ensuring the driving safety of the automobile.

[0071] 2. Car rearview mirror system

[0072] In this embodiment, the automobile rearview mirror system includes a first automobile rearview mirror device and a second automobile rearview mirror device, both of which are Figure 1 、 Figure 2 or Figure 3 The vehicle rearview mirror device shown in the figure includes two vehicle rearview mirror devices, one of which is a first vehicle rearview mirror device installed on the left side of the vehicle body as a left rearview mirror, and the other is a second vehicle rearview mirror device installed on the right side of the vehicle body as a right rearview mirror.

[0073] In this embodiment, refer to Figure 4 The vehicle rearview mirror system also includes a master control unit, a first tire pressure monitoring unit, and a second tire pressure monitoring unit. In this embodiment, the master control unit can be the vehicle's electronic control unit (ECU), or the control unit in the first or second vehicle rearview mirror device can serve as the master control unit. The first tire pressure monitoring unit is installed on the left front wheel and is used to monitor the tire pressure of the left front wheel; the second tire pressure monitoring unit is installed on the right front wheel and is used to monitor the tire pressure of the right front wheel.

[0074] The master control unit can set a series of sampling times t1, t2, t3...t n For example, at sampling time t1, the height value range H output by the first rearview mirror device is received. 0L1 (represents the relative height between the mirror body and the fixing unit in the first rearview mirror device that can minimize the vibration of the first rearview mirror device at time t1), the height value range H output by the second rearview mirror device 0R1 (representing the relative height between the mirror body and the fixing unit in the first rearview mirror device that can minimize the vibration of the second rearview mirror device at time t1), the left tire pressure information P detected by the first tire pressure detection unit L1 (representing the tire pressure of the left front wheel at time t1) and the right tire pressure information P detected by the second tire pressure detection unit R1 (represents the tire pressure of the right front wheel at time t1); similarly, at sampling time t1, the height value range H output by the first rearview mirror device is received 0L2 , the height value range H output by the second automobile rearview mirror device 0R2 , the left tire pressure information P detected by the first tire pressure detection unit L2 and the right tire pressure information P detected by the second tire pressure detection unit R2 ...Thus, we obtain the multiple time series shown in Table 1.

[0075] Table 1

[0076]

[0077] In Table 1, the height difference information ΔH1, ΔH2, ΔH3...ΔH n Indicates that at sampling time t1, t2, t3...t n The difference between the relative height (range) of the first rearview mirror device to minimize vibration and the relative height (range) of the second rearview mirror device to minimize vibration, tire pressure difference information ΔP1, ΔP2, ΔP3...ΔP n Indicates that at sampling time t1, t2, t3...t n The actual air pressure difference between the left and right tires.

[0078] In this embodiment, when the master control unit performs the step of safety monitoring based on the tire pressure difference information and the height difference information, the master control unit can specifically monitor the tire pressure difference information ΔP1, ΔP2, ΔP3, ..., ΔP n and height difference information ΔH1, ΔH2, ΔH3...ΔH n Perform dynamic tracking and detect tire pressure difference information ΔP1, ΔP2, ΔP3...ΔP n and height difference information ΔH1, ΔH2, ΔH3...ΔH n The change correlation of .

[0079] In this embodiment, the tire pressure difference information ΔP1, ΔP2, ΔP3 ... ΔP can be calculated. n and height difference information ΔH1, ΔH2, ΔH3...ΔH n Quantitative indicators such as the cross-correlation coefficient, Pearson correlation coefficient, waveform similarity, and dynamic time warping between the two time series are used as the change correlation (positive numbers indicate positive correlation, negative numbers indicate negative correlation, and the absolute value can be taken as the change correlation). The change correlation indicates the degree of correlation between the two time series over time. Since tire pressure affects tire shape, which in turn affects the ground clearance of the first and second rearview mirror devices, the tire pressure difference information will affect the height difference information. The change correlation can also indicate the extent of the impact of the tire pressure difference information on the height difference information.

[0080] In this embodiment, when n is large enough (for example, a threshold N is set, and when n≥N, it is determined that n is large enough), that is, the tire pressure difference information ΔP1, ΔP2, ΔP3...ΔP n and height difference information ΔH1, ΔH2, ΔH3...ΔH n When the time interval is long enough, the correlation between the tire pressure difference information and the height difference information is calculated.

[0081] In this embodiment, a threshold value may be set to indicate the magnitude of the change correlation. When the calculated change correlation is less than the threshold value, the tire pressure difference information ΔP1, ΔP2, ΔP3, ... ΔP is determined. n and height difference information ΔH1, ΔH2, ΔH3...ΔH n The correlation between these two time series is small, thus generating safety warning information.

[0082] In this embodiment, the principle of the master control unit generating a safety reminder message when the change correlation is small is that under ideal conditions (for example, the vehicle body is normal and balanced, the tire pressure is normal and balanced, etc.), the air pressure of the left and right tires is the same, and the tire pressure difference information ΔP1, ΔP2, ΔP3...ΔP n is an all-zero sequence (constant sequence), the first rearview mirror device and the second rearview mirror device on both sides have the same working conditions and are in a balanced state (for example, the initial setting height of each mirror body from the ground is the same, and the height difference information corresponding to each mirror body when the vibration is minimum is also the same), the height difference information ΔH1, ΔH2, ΔH3...ΔH nIt is also an all-zero sequence (constant sequence), and the correlation between the two time series is very large (greater than a threshold value); in the case of deviation from the ideal situation (for example, the overall heights of the first automobile rearview mirror device and the second automobile rearview mirror device are different), the two sequences may each change over time; among them, if the correlation between the two time series is still at a large level (greater than a threshold value), it indicates that the overall heights of the first automobile rearview mirror device and the second automobile rearview mirror device are different, resulting in the deviation of the height difference information from the ideal situation over time, which is mainly caused by the change of tire pressure difference information over time, such as the uneven leakage rate of the tires on both sides. These abnormal situations themselves are safely monitored by the tire pressure monitoring system, so there is no need for the automobile rearview mirror system to generate safety reminder information; on the contrary, if the correlation between the two time series is at a small level (less than a threshold value), then it indicates that the overall heights of the first automobile rearview mirror device and the second automobile rearview mirror device are different, resulting in the deviation of the height difference information from the ideal situation over time, which may be caused by the tire pressure difference information Caused by factors other than changes over time, such as failure of components such as the height adjustment unit of the first automobile rearview mirror device or the second automobile rearview mirror device, resulting in imbalance of the mirror bodies of the first automobile rearview mirror device and the second automobile rearview mirror device (for example, the initial settings of the respective mirror bodies are at different heights above the ground, resulting in the need to adjust both mirror bodies to a specific and identical height above the ground in order to put their respective mirror bodies in a state of minimum vibration, which results in different height difference information corresponding to the first automobile rearview mirror device and the second automobile rearview mirror device at the same time), damage to the vehicle body resulting in imbalance of the mirror bodies of the first automobile rearview mirror device and the second automobile rearview mirror device, suspension system failure resulting in imbalance of the mirror bodies of the first automobile rearview mirror device and the second automobile rearview mirror device, etc. These abnormal conditions are relatively more hidden, so the automobile rearview mirror system generates a safety reminder message, and can send the safety reminder message to the vehicle display screen, or push it to the vehicle user's mobile phone or other terminal, so as to remind the user to check the vehicle, etc., which is conducive to discovering and troubleshooting and ensuring traffic safety.
