Description

Technical Field

[0001] This invention relates to the field of towable caravan technology, and more particularly to an intelligent interactive UI monitoring system for towable caravans. Background Technology

[0002] Currently, towable caravans, due to their large size, are prone to swaying during operation due to road conditions and other factors, affecting driving safety. Simultaneously, the synchronicity of the braking system is crucial for vehicle stability. The market currently lacks a user interface specifically designed for anti-swaying and braking synchronization control in caravans. This makes it difficult for drivers to accurately grasp and adjust related settings, increasing driving difficulty and safety hazards, and failing to meet the modern caravan users' demands for convenience and intelligence. Therefore, we propose an intelligent interactive UI monitoring system for towable caravans. Summary of the Invention

[0003] The present invention proposes an intelligent interactive UI monitoring system for towable RVs, which solves the problem that the user interfaces on the market make it difficult for drivers to accurately grasp and adjust relevant settings, increasing driving difficulty and safety hazards, and failing to meet the needs of modern RV users for convenience and intelligence.

[0004] To achieve the above objectives, the present invention adopts the following technical solution:

[0005] A smart interactive UI monitoring system for a towable RV 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 display module for displaying the magnitude of the RV's braking force, an acceleration display module for displaying the magnitude of the RV's body acceleration, and an offset angle display module for displaying the magnitude of the RV's body offset angle. The braking force display module is electrically connected to a current sensor via a controller. The offset angle display module is simultaneously connected to a six-axis gyroscope and an angle sensor via the controller. The six-axis gyroscope is also electrically connected to the acceleration display module via the controller.

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

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

[0008] Preferably, the six-axis gyroscope is used to collect 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 size display module through the controller. When the detected acceleration in the two directions exceeds the set threshold, the motor home body sway or braking is judged through the controller.

[0009] Preferably, the six-axis gyroscope and the angle sensor jointly capture the included angle between the motor home and the horizontal direction of the road, and display it on the offset angle size display module through the controller. The six-axis gyroscope adopts a pose solving algorithm and a dynamic Kalman filtering algorithm. When the six-axis gyroscope performs pose solving, it first uses Taylor's expansion for approximation, thereby obtaining the Euler angle θ(t+Δt)≈θ(t)+ω(t)Δt along the X-axis, θ(t) is the current angle, ω(t) is the angular velocity, and Δt is the time change amount; similarly, the Euler 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 amount; similarly, the Euler 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 amount.

[0010] When the six-axis gyroscope performs dynamic Kalman filtering algorithm operation, first look at the state equation: represents the state at the last time, F is the conversion array, represents the external control amount, represents a random variable; next look at the observation equation: H is the conversion matrix, is the measurement error, and obeys the Gaussian distribution; the next step is to establish a model under the given measurement state, thereby predicting the state at the next time, and verifying the maximum probability, and extracting the Kalman gain in the process of verifying the maximum probability, and the specific formula is as follows:

[0011]

[0012]

[0013]

[0014] The above formula (1), (2) and (3) can directly measure the basis of the observation equation H, and finally obtain the current attitude of the house car.

[0015] Preferably, the anti-rolling degree level setting module is used for the driver to set the anti-rolling degree level of the house car, and the anti-rolling degree level setting module displays the anti-rolling degree level parameter set by the driver and sends it to the personalized setting and memory module for saving. The anti-rolling degree level of the house car is divided into high and low. The lateral rolling acceleration threshold of the high-level anti-rolling degree exceeds 0.6g / m 2 , and the lateral rolling acceleration threshold of the low-level anti-rolling degree exceeds 0.4g / m 2 .

[0016] Preferably, the brake response speed setting module is used for the driver to set the brake response speed of the house car, and the brake response speed setting module displays the brake response speed parameter set by the driver and sends it to the personalized setting and memory module for saving. The brake response speed is set to high, medium and low. The electromagnetic brake of the high-level brake response speed outputs 50% of the maximum voltage, the electromagnetic brake of the medium-level brake response speed outputs 30% of the maximum voltage, and the electromagnetic brake of the low-level brake response speed outputs 10% of the maximum voltage.

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

[0018] Preferably, the multi-dimensional data monitoring and display module is also connected with 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 house car is excessively rolling or the brake is out of synchronization, 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 house car is excessively rolling and the brake system has not intervened, it controls the anti-rolling degree level setting module to reduce the anti-rolling degree level and display it. When the intelligent early warning and intervention module identifies that the brake of the house car does not achieve synchronization, it controls the brake response speed setting module to set the brake response speed and display it.

[0019] Preferably, the multi-dimensional data monitoring and display module is also connected with the adaptive adjustment module. The adaptive adjustment module is used to set the "one-key alignment" operation in the options through the screen. The adaptive adjustment module can also perform "one-key anti-rolling and brake synchronization optimization" operation. After the "one-key anti-rolling and brake synchronization optimization" operation, the electromagnetic brake of the house car will be delayed from zero to maximum output, reducing the impact when the brake force is quickly output.

[0020] Compared with the prior art, the application greatly improves the control ability of the driver of the house car on the stability and braking performance of the vehicle, reduces the driving difficulty, improves the driving safety, and enhances the user experience.
