Vehicle Oscillation Stabilization via Braking and Torque Control
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Vehicles, particularly motorcycles, are susceptible to speed-induced oscillations such as high-speed shimmy or wobble, which can lead to loss of control and accidents if not addressed effectively by existing stabilization systems.
Innovation Solution
A system comprising a sensor to detect oscillations and an electronic processor that compares the oscillation signal to a detection threshold, activating the braking system and reducing engine torque to stabilize the vehicle.

Engineering Contradiction Analysis
1Productivity
If the vehicle operates at high speed, then productivity is improved, but speed-induced oscillation occurs causing loss of control
Solution Approach 1:
The sensor continuously monitors oscillation parameters before they reach dangerous levels. The electronic processor compares oscillation signals against predetermined thresholds and activates the braking system in advance, before complete loss of control occurs. This preliminary detection and intervention allows the vehicle to maintain high speed operation while preventing oscillation from escalating to unsafe levels.
2Reliability
If oscillation detection and correction systems are added, then vehicle stability is improved, but device complexity increases
Solution Approach 1:
The system employs a feedback mechanism where the sensor continuously monitors oscillation parameters, the electronic processor compares these parameters against predetermined thresholds, and the braking system is activated based on the comparison results. This closed-loop feedback control stabilizes the vehicle by automatically responding to oscillation conditions while maintaining relatively simple system architecture through direct threshold-based control logic.
3Reliability
If braking system is activated to stop oscillation, then vehicle stability is improved, but loss of time occurs during stabilization
Solution Approach 1:
The system activates the braking system as soon as oscillation parameters exceed the predetermined threshold, rather than waiting for oscillation to fully develop. This preliminary intervention stops oscillation in its early stages, minimizing the time the vehicle spends in an unstable condition while still achieving effective stabilization.

AI summary
Systems and methods for detecting an oscillation of a vehicle. The system comprises a sensor configured to detect an oscillation of the vehicle, and an electronic controller configured to receive an oscillation signal from the sensor, compare the oscillation signal to a detection threshold, and in response to the comparison of the oscillation signal to the detection threshold, generate a signal to activate a braking system of the vehicle and generate a request to reduce torque in an engine of the vehicle.
