Vehicle Tilting Lock Control for Low-Speed Sway Stability
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing vehicles with tiltable mechanisms face instability at low speeds, leading to potential rollover and safety risks for drivers due to uncontrolled swaying of the main frame.
Innovation Solution
A tilting device for vehicles incorporating a main frame, a steering mechanism, a detent mechanism, and a control mechanism. The detent mechanism includes electronically controlled hydraulic rods that can lock or unlock to control the tilt angle of the vehicle, and the control mechanism automatically adjusts the tilt angle to maintain balance and prevent swaying.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a tiltable mechanism is provided to improve rollover resistance during turning, then the vehicle can produce sufficient positive pressure against the ground to balance centrifugal force, but the main frame sways side to side at low speeds or when stopped, causing the vehicle to roll over
Solution Approach 1:
The patent applies a dynamic control approach by using a control mechanism that automatically adjusts the tilt angle based on vehicle operating conditions. The detent mechanism is controlled to lock or unlock based on speed and tilt angle parameters, allowing the system to adapt between stable locked state at low speeds and flexible unlocked state during turning, thus resolving the contradiction between rollover resistance and main frame stability
Solution Approach 2:
The control mechanism receives feedback from detection mechanisms (such as speed sensors and tilt angle sensors) to automatically adjust the detent mechanism. This closed-loop control system monitors vehicle state and dynamically adjusts the tilt angle control, enabling the system to maintain stability at low speeds while providing necessary tilt capability during turning operations
2Adaptability or versatility
If the tiltable mechanism is unlocked to allow tilt adjustment, then the vehicle can tilt during turning to balance centrifugal force, but the vehicle becomes unstable at low speeds with poor road surface conditions
Solution Approach 1:
The system dynamically switches between locked and unlocked states of the detent mechanism based on real-time vehicle conditions. At low speeds, the mechanism locks to provide stability, while during turning at higher speeds, it unlocks to allow tilt adjustment for balancing centrifugal force, thus achieving both stability and adaptability
3Stability of the object's composition
If the detent mechanism is locked to prevent swaying, then the main frame remains stable at low speeds, but the vehicle cannot tilt to balance centrifugal force during turning
Solution Approach 1:
The detent mechanism transitions from a static locked state to a dynamic controlled state, where it can switch between locked and unlocked conditions based on vehicle speed and tilt angle. This dynamic behavior allows the system to maintain stability when locked at low speeds and enable tilt functionality when unlocked during turning operations

This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The tilting device effectively prevents the vehicle from swaying left and right, enhancing driver safety by automatically controlling the tilt angle and maintaining the main frame in a balanced state, even at low speeds.
Implementation Method 1
the hydraulic rod body comprises a cylinder body and a piston assembly; the piston is disposed in the cylinder body and comprises a first surface and a second surface opposite to the first surface; the piston divides the cylinder body into a first chamber located on the side of the first surface of the piston and a second chamber located on the side of the second surface of the piston
