[0070] The intelligent switching unit automatically switches the control mode according to the operation signal.

[0071] Control method:

[0072] Intelligent multi-modal control: The dual-mode control unit adopts an intelligent multi-modal control strategy, which can select the most appropriate control algorithm in real time according to the actual operating status of the system. By executing different control algorithms under different operating conditions, adjusting parameters, and choosing the right time to switch, the optimal combination of performance indicators reflecting system stability, accuracy and speed can be achieved.

[0073] Multi-mode switching control technology: Specific application methods include variable gain control, sliding mode control and artificial intelligence control. Variable gain control makes full use of the existing linear control design method, requiring that the system state must be slowly time-varying and additional gain variables must be defined; sliding mode control provides an effective method for robust control of uncertain systems, but still needs to overcome the jitter problem existing in actual systems.

[0074] Control methods based on artificial intelligence: Artificial intelligence technology has obvious advantages in modal identification, simulation of human brain reasoning and control. Therefore, more and more multimodal control systems choose intelligent control methods as the control strategy under each mode to cope with complex controlled objects and processes and achieve more ideal automatic control.

[0075] Specific control algorithm:

[0076] Fuzzy control method and lag-lead correction method: The dual-mode control unit uses a dual-mode control technology that combines fuzzy control method and lag-lead correction method to improve the response speed, anti-interference performance and reduce overshoot of the electric power stroller. Fuzzy control starts from human experience and implements control based on fuzzy set theory, fuzzy language variables and fuzzy reasoning, solving the description and reasoning problems of human language in intelligent control.

[0077] Switch control and ripple-free minimum beat control: When the deviation is large at the beginning of control, switch control (bangbang control) is used to achieve fast coarse positioning; when the control is nearing the end and the deviation is small, ripple-free minimum beat control is used to achieve time-limited fine positioning, thereby achieving the purpose of fast and accurate positioning.

[0078] Dual-mode Smith predictive control algorithm with gain and phase compensation: To address the possible object model mismatch problem, a dual-mode Smith predictive control algorithm with gain and phase compensation is proposed, which can effectively improve the effect of Smith predictive control and enhance the system's adaptability.

[0079] Sensors and signal monitoring

[0080] Sensor integration: In order to perceive the environment and operation intention, the intelligent switching mechanism uses slope sensors, distance sensors, etc. to monitor the environment of the stroller and the user's control intention in real time. These sensors can detect information such as slope and obstacles, providing a basis for intelligent switching.

[0081] Signal monitoring: The system constantly monitors the signal strength and stability of the wireless remote control module. When the signal is weak or interrupted, the mechanism will automatically switch to the manual module to prevent loss of control.

[0082] Algorithms and Logic

[0083] Intelligent algorithms: Intelligent switching mechanisms use advanced algorithms, such as fuzzy logic control or artificial intelligence algorithms, to achieve more accurate mode identification and control. These algorithms can quickly make correct switching decisions based on complex sensor data.

[0084] Logic preset: The system is designed with a variety of logic conditions to ensure that the most appropriate control mode can be selected in various situations. For example, when the wireless remote control module signal is strong and stable, the wireless remote control mode is selected; when the signal is weak or the manual operation force is greater than the set value, it switches to the manual control mode.

[0085] Security and stability

[0086] Emergency response: In emergency situations, such as accidental release or rapid downhill movement, the intelligent switching mechanism will immediately initiate automatic braking measures to prevent the stroller from losing control.

[0087] Stability guarantee: The mechanism maintains a smooth transition during the switching process to avoid instability caused by sudden switching. At the same time, the system will continue to monitor sensor data before and after the switch to ensure the stable operation of the control mode.

[0088] Battery life and power management

[0089] Battery design: The intelligent switching mechanism is equipped with a rechargeable battery and provides long-lasting battery life. At the same time, the system will intelligently adjust the working mode according to the current power level to extend the use time.

[0090] Power management: The mechanism dynamically distributes power between the wireless remote control module and the manual operation module to ensure that all parts can operate efficiently. At the same time, the system will periodically enter low-power mode to reduce energy consumption.

[0091] User experience and scalability

[0092] Improved convenience: The intelligent switching mechanism greatly improves the convenience and adaptability of the stroller. Users do not need to manually switch control modes, the system will automatically select the best solution, making operation simpler and more natural.

[0093] Expansion compatibility: The mechanism is designed with standardized interfaces and modular structures to facilitate future upgrades and expansions. Users can add new sensors or control modules according to their needs to enhance the functions of the stroller.

[0094] Application cases and actual results

[0095] Closed scenes in shopping malls: In closed scenes such as shopping malls, users may face signal blockage or interference. The intelligent switching mechanism will automatically detect and switch to manual mode to ensure that the stroller can still operate smoothly.

[0096] Complex outdoor environments: In complex outdoor environments, such as hillsides or crowded streets, the mechanism will automatically adjust the control mode based on the slope and obstacle information, so that the stroller can maintain stable movement under different road conditions.

[0097] When the safety protection unit detects emergency situations such as rapid descent or accidental loosening, the emergency braking system will be activated immediately. In addition to automatic triggering, the emergency braking system is also equipped with a manual control button, which allows users to quickly brake when needed. The integrated anti-rollover sensor can monitor the tilt angle of the stroller in real time. When the angle exceeds the safe range, the electric power stroller's built-in drive system will automatically adjust to maintain balance.

[0098] Among them, the intelligent switching mechanism:

[0099] Signal monitoring and automatic switching: The system constantly monitors the signal strength and stability of the wireless remote control module. When the signal is weak or interrupted, the mechanism will automatically switch to the manual operation module to avoid loss of control due to signal problems.

[0100] Theoretical support: This step is based on signal processing and communication theory. By real-time monitoring of signal parameters such as signal-to-noise ratio and bit error rate, the quality and stability of the signal can be judged to determine whether to switch modes.

[0101] Emergency Braking:

[0102] Quick response mechanism: When emergency situations such as rapid downhill or accidental release are detected, the emergency brake system will be activated immediately to prevent the stroller from losing control.

[0103] Theoretical support: This step relies on the principles of mechanics and dynamic models. By analyzing data such as the acceleration and tilt angle of the stroller, it can determine whether there is a risk of tipping over or losing control and respond quickly.

[0104] Anti-tip sensor:

[0105] Tilt Angle Monitoring: The integrated anti-tip sensor can monitor the tilt angle of the stroller in real time. When the angle exceeds the safe range, the system will automatically adjust to maintain balance.

[0106] Theoretical support: This function is based on gravity sensing technology and geometric stability theory. It monitors the posture and tilt angle of the stroller in real time and combines the principles of geometry and physics to determine and prevent the risk of tipping over.
