Hybrid Balancing Control for Motorized Vehicle Stability
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing light motorized vehicles with balancing means require either fully manual control, which is inconvenient at low speeds and on uneven ground, or fully automatic systems that are costly and power-intensive, limiting their accessibility and safety.
Innovation Solution
A hybrid balancing system that switches between manual and automatic control based on vehicle speed and sensors, ensuring the vehicle remains upright at stops even on non-horizontal ground, using a clutch or electronic means to activate automatic balancing when necessary and allowing manual control at higher speeds.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Speed
If fully manual balancing control is used, then the vehicle can be operated at higher speeds with simple control, but the driver cannot maintain stability at low speeds and on uneven ground
Solution Approach 1:
The patent implements a dynamic control system that automatically switches between manual and automatic balancing modes based on vehicle speed. At high speeds, manual control is sufficient and preferred. At low speeds and during stops, the system transitions to automatic control to maintain stability. This dynamic adaptation resolves the contradiction by optimizing the control mode according to operating conditions.
2Reliability
If fully automatic balancing means are used, then the vehicle maintains stability at low speeds and stops, but the system requires high power and increases cost
Solution Approach 1:
The patent employs periodic or conditional activation of the automatic balancing system rather than continuous operation. The automatic system is activated only when sensors detect low-speed conditions or instability, and deactivated when manual control is sufficient. This periodic action maintains reliability when needed while significantly reducing average power consumption and cost.
3Reliability
If fully automatic balancing means are used, then the vehicle maintains stability at low speeds and stops, but the system complexity and cost increase
Solution Approach 1:
The patent segments the balancing system into two distinct modes: manual balancing control and automatic balancing control. Each mode is optimized for specific operating conditions. The system includes a switching mechanism that divides the control function between driver input and automatic sensor-based control, reducing overall system complexity compared to a fully automatic system while maintaining stability when needed.
4Device complexity
If manual balancing control is used, then the system is simpler and cheaper, but the driver must continuously control equilibrium which is difficult at low speeds and stops
Solution Approach 1:
The patent introduces sensors as an intermediary between the driver and the balancing control system. These sensors detect vehicle inclination, speed, and stability conditions, providing information that triggers automatic intervention when needed. This intermediary layer reduces the driver's control effort at critical moments while maintaining overall system simplicity through selective automatic activation.

AI summary
The motor vehicle of the invention is provided with at least three wheels and includes a driving cab capable of accommodating a single person in the width direction. The motor vehicle comprises a bend-balancing means that acts by the inclination of at least the portion of the chassis that bears the driving cab. According to the invention, the vehicle is also provided with speed, acceleration and/or inclination sensors, and the balancing means are automatically controlled when the information supplied by the sensors is lower than a main predetermined threshold. The invention also provides that the automatic control of the balancing means is deactivated when the information provided by the sensors is higher than said main threshold.
