Technical Field

[0001] The present invention relates to the technical field of trailer caravans, and in particular to an intelligent interactive UI monitoring system for trailer caravans. Background Art

[0002] At present, trailer RVs are large in size and are prone to swaying due to factors such as road conditions during driving, which affects driving safety. At the same time, the synchronization of the braking system is also crucial to vehicle stability. At present, there is a lack of a user interface specifically for RV anti-sway and braking synchronization control on the market, which makes it difficult for drivers to accurately master and adjust related settings, increasing driving difficulty and safety hazards, and it is difficult to meet the needs of modern RV users for convenience and intelligence. Based on this, we propose an intelligent interactive UI monitoring system for trailer RVs. Summary of the invention

[0003] The intelligent interactive UI monitoring system for trailer RVs proposed in the present invention solves the problem that the user interfaces currently on the market make it difficult for drivers to accurately master and adjust relevant settings, increase driving difficulty and safety hazards, and are difficult to meet the needs of modern RV users for convenience and intelligence.

[0004] In order to achieve the above object, the present invention adopts the following technical solutions:

[0005] A trailer-type RV intelligent interactive UI monitoring system includes a multi-dimensional data monitoring and display module, an intelligent early warning and intervention module, an adaptive control adjustment module, and a personalized setting and memory module. The multi-dimensional data monitoring and display module includes a data monitoring and display module and a function setting display module. The data monitoring and display module includes a braking force size display module for displaying the braking force size of the RV, an acceleration size display module for displaying the acceleration size of the RV body, and a deviation angle size display module for displaying the deviation angle size of the RV body. The braking force size display module is electrically connected to a current sensor through a controller, and the deviation angle size display module is simultaneously connected to a six-axis gyroscope and an angle sensor through the controller. The six-axis gyroscope is also electrically connected to the acceleration size display module through the controller.

[0006] The function setting display module includes an anti-sway level setting module, a brake response speed setting module and a brake mode selection setting module. The anti-sway level setting module, the brake response speed setting module and the brake mode selection setting module are all connected to the personalized setting and memory module.

[0007] Preferably, the current sensor is used to detect the current value of the electromagnetic brake in real time and transmit it to the controller. The controller converts the current value transmitted by the current sensor into braking force through a formula and displays it on the instrument panel of the braking force display module.

[0008] Preferably, the six-axis gyroscope is used to collect real-time acceleration in the lateral and forward directions, and perform moving weighted average filtering on the collected real-time acceleration, and then display the detected acceleration on the acceleration magnitude display module through the controller. When the acceleration in the two directions detected by the six-axis gyroscope exceeds the set threshold, it determines whether the RV body is swaying or braking through the controller.

[0009] Preferably, the six-axis gyroscope and the angle sensor jointly capture the angle between the RV and the horizontal direction of the road surface, and display it on the offset angle display module through the controller. The six-axis gyroscope adopts an attitude solution algorithm and a dynamic Kalman filter algorithm, wherein the six-axis gyroscope first uses the Taylor-Metric expansion for approximation when performing attitude solution, thereby obtaining the Ohm's angle θ(t+Δt)≈θ(t)+ω(t)Δt rotating along the X-axis, θ(t) is the current angle, ω(t) is the angular velocity, and Δt is the time change; similarly, the Ohm's angle γ(t+Δt)≈γ(t)+ω(t)Δt along the Y-axis, γ(t) is the current angle, ω(t) is the angular velocity, and Δt is the time change; similarly, the Ohm's angle ψ(t+Δt)≈ψ(t)+ω(t)Δt along the Z-axis, Ψ(t) is the current angle, ω(t) is the angular velocity, and Δt is the time change;

[0010] When the six-axis gyroscope performs dynamic Kalman filter algorithm calculation, first look at the state equation: represents the state at the previous moment, F is the conversion array, represents the external control quantity, represents a random variable; the next step is to look at the observation equation: H is the transformation matrix, is the measurement error, and It conforms to the Gaussian distribution; the next step is to establish a model under a given measurement state to predict the state at the next moment, and at the same time verify the maximization of the probability. In the process of verifying the maximization probability, the Kalman gain is extracted. The specific formula is as follows:

[0011]

[0012]

[0013]

[0014] The above formulas (1), (2) and (3) are based on the fact that H can be directly measured in the observation equation, and finally the current posture of the RV is obtained.

[0015] Preferably, the anti-sway level setting module is used for the driver to set the anti-sway level of the RV. The anti-sway level setting module displays the anti-sway level parameters set by the driver and sends them to the personalized setting and memory module for storage. The anti-sway level of the RV is divided into high and low. The lateral sway acceleration threshold of the high level anti-sway level exceeds 0.6g / m 2 The lateral sway acceleration threshold of the low-level anti-sway level exceeds 0.4g / m 2 .

[0016] Preferably, the braking response speed setting module is used for the driver to set the braking response speed of the RV. The braking response speed setting module displays the braking response speed parameters set by the driver and sends them to the personalized setting and memory module for storage. The braking response speed is set to high, medium and low. The high-level braking response speed is 50% of the maximum starting output voltage of the electromagnetic brake, the medium-level braking response speed is 30% of the maximum starting output voltage of the electromagnetic brake, and the low-level braking response speed is 10% of the maximum starting output voltage of the electromagnetic brake.

[0017] Preferably, the braking mode selection and setting module is used for the driver to select a braking mode. The braking mode selection and setting module displays the braking mode selected by the driver and sends it to the personalized setting and memory module for storage.

[0018] Preferably, the multidimensional data monitoring and display module is also connected to the intelligent early warning and intervention module, which is used to identify unstable factors. When the intelligent early warning and intervention module identifies that the RV is swaying excessively or the braking is not synchronized, it controls the multidimensional data monitoring and display module to issue a warning; when the intelligent early warning and intervention module identifies that the RV is swaying excessively and the braking system is not intervened, it controls the anti-sway level setting module to lower the anti-sway level and display it; when the intelligent early warning and intervention module identifies that the braking of the RV has not achieved a synchronous effect, it controls the braking response speed setting module to set the braking response speed and display it.

[0019] Preferably, the multidimensional data monitoring and display module is also connected to the adaptive adjustment module, which is used to perform the "one-button balancing" operation in the setting options through the screen. The adaptive adjustment module can also perform the "one-button anti-sway and braking synchronization optimization" operation. After the "one-button anti-sway and braking synchronization optimization" operation, the electromagnetic brake of the RV will be delayed from zero to maximum output to reduce the impact when the braking force is output quickly.

[0020] Compared with the prior art, the present invention greatly improves the RV driver's ability to control vehicle stability and braking performance, reduces driving difficulty, improves driving safety, and also enhances user experience. BRIEF DESCRIPTION OF THE DRAWINGS

[0022] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0023] Reference Figure 1 A trailer-type RV intelligent interactive UI monitoring system includes a multi-dimensional data monitoring and display module, an intelligent early warning and intervention module, an adaptive control adjustment module, and a personalized setting and memory module. The multi-dimensional data monitoring and display module includes a data monitoring display module and a function setting display module. The data monitoring display module includes a braking force display module for displaying the braking force of the RV, an acceleration display module for displaying the acceleration of the RV body, and an offset angle display module for displaying the offset angle of the RV body. The braking force display module is electrically connected to a current sensor through a controller. The current sensor is used to detect the current value of the electromagnetic brake in real time and transmit it. The controller converts the current value transmitted by the current sensor into braking force through a formula, and displays it on the dashboard of the braking force display module for the convenience of observation by the driver. The offset angle display module is connected to the six-axis gyroscope and the angle sensor through the controller at the same time. The six-axis gyroscope is also electrically connected to the acceleration display module through the controller. The six-axis gyroscope is used to collect real-time acceleration in the lateral and forward directions, and performs moving weighted average filtering on the collected real-time acceleration, and then displays the detected acceleration on the acceleration display module through the controller. When the acceleration in the two directions detected by the six-axis gyroscope exceeds the set threshold, it determines whether the RV body is swaying or braking through the controller;

[0024] The function setting display module includes an anti-sway level setting module, a brake response speed setting module and a brake mode selection setting module, and the anti-sway level setting module, the brake response speed setting module and the brake mode selection setting module are all connected to the personalized setting and memory module;

[0025] The multi-dimensional data monitoring and display module is also connected to the intelligent early warning and intervention module. The intelligent early warning and intervention module is used to identify unstable factors. When the intelligent early warning and intervention module identifies that the RV is swaying excessively or the braking is not synchronized, it controls the multi-dimensional data monitoring and display module to issue an early warning; when the intelligent early warning and intervention module identifies that the RV is swaying excessively and the braking system is not intervened, it controls the anti-sway degree setting module to reduce the anti-sway degree and display it; when the intelligent early warning and intervention module identifies that the braking of the RV has not achieved a synchronous effect, it controls the braking response speed setting module to set the braking response speed and display it;

[0026] The multi-dimensional data monitoring and display module is also connected to the adaptive adjustment module. The adaptive adjustment module is used to perform the "one-key balancing" operation in the setting options through the screen. The adaptive adjustment module can also perform the "one-key anti-sway and braking synchronization optimization" operation. After the "one-key anti-sway and braking synchronization optimization" operation, the electromagnetic brake of the RV will be delayed from zero to maximum output to reduce the impact when the braking force is output quickly. The present invention greatly improves the RV driver's ability to control vehicle stability and braking performance, reduces driving difficulty, improves driving safety, and also enhances user experience.

[0027] Specifically, the six-axis gyroscope and the angle sensor jointly capture the angle between the RV and the horizontal direction of the road surface, and display it on the offset angle display module through the controller. The six-axis gyroscope adopts an attitude solution algorithm and a dynamic Kalman filter algorithm. The six-axis gyroscope first uses the Taylor-Metric expansion to approximate the attitude solution, thereby obtaining the Ohm's angle θ(t+Δt)≈θ(t)+ω(t)Δt rotating along the X-axis, where θ(t) is the current angle, ω(t) is the angular velocity, and Δt is the time change; similarly, the Ohm's angle γ(t+Δt)≈γ(t)+ω(t)Δt along the Y-axis, where γ(t) is the current angle, ω(t) is the angular velocity, and Δt is the time change; similarly, the Ohm's angle ψ(t+Δt)≈ψ(t)+ω(t)Δt along the Z-axis, where Ψ(t) is the current angle, ω(t) is the angular velocity, and Δt is the time change;

[0028] When the six-axis gyroscope performs dynamic Kalman filter algorithm calculation, first look at the state equation: represents the state at the previous moment, F is the conversion array, represents the external control quantity, represents a random variable; the next step is to look at the observation equation: H is the transformation matrix, is the measurement error, and It conforms to the Gaussian distribution; the next step is to establish a model under a given measurement state to predict the state at the next moment, and at the same time verify the maximization of the probability. In the process of verifying the maximization probability, the Kalman gain is extracted. The specific formula is as follows:

[0029]

[0030]

[0031]

[0032] The above formulas (1), (2) and (3) are based on the fact that H can be directly measured in the observation equation, and finally the current posture of the RV is obtained.

[0033] Furthermore, the anti-sway level setting module is used for the driver to set the anti-sway level of the RV. The anti-sway level setting module displays the anti-sway level parameters set by the driver and sends them to the personalized setting and memory module for storage. The anti-sway level of the RV is divided into high and low. The lateral sway acceleration threshold of the high level anti-sway level exceeds 0.6g / m 2 The lateral sway acceleration threshold of the low-level anti-sway level exceeds 0.4g / m 2 The braking response speed setting module is used for the driver to set the braking response speed of the RV. The braking response speed setting module displays the braking response speed parameters set by the driver and sends them to the personalized setting and memory module for storage. The braking response speed is set to high, medium and low. The electromagnetic brake starting output voltage of the high-level braking response speed is 50%, the electromagnetic brake starting output voltage of the medium-level braking response speed is 30%, and the electromagnetic brake starting output voltage of the low-level braking response speed is 10%. The braking mode selection setting module is used for the driver to select the braking mode. The braking mode selection setting module displays the braking mode selected by the driver and sends it to the personalized setting and memory module for storage.

[0034] The operating principle of this embodiment is as follows:

[0035] The current sensor is used to detect the current value of the electromagnetic brake in real time and transmit it to the controller. The controller converts the current value transmitted by the current sensor into braking force through a formula and displays it on the instrument panel of the braking force display module.

[0036] The six-axis gyroscope is used to collect the real-time acceleration in the lateral and forward directions, and the collected real-time acceleration is subjected to moving weighted average filtering, and then the detected acceleration is displayed on the acceleration magnitude display module through the controller;

[0037] The six-axis gyroscope and angle sensor are used to capture the horizontal angle between the RV and the road surface, and the offset angle size display module is displayed through the controller;

[0038] The intelligent early warning and intervention module is used to identify unstable factors. When the intelligent early warning and intervention module identifies that the RV is swaying excessively or the braking is not synchronized, it controls the multi-dimensional data monitoring and display module to issue a warning; when the intelligent early warning and intervention module identifies that the RV is swaying excessively and the braking system is not intervened, it controls the anti-sway level setting module to reduce the anti-sway level and display it; when the intelligent early warning and intervention module identifies that the braking of the RV has not achieved a synchronous effect, it controls the braking response speed setting module to set the braking response speed and display it; from the above, it can be seen that the RV driver's ability to control vehicle stability and braking performance has been greatly improved, which also reduces the difficulty of driving, improves driving safety, and also enhances the user experience.
